How Much Nitrous Can a Stock Engine Take? - Engine Masters Ep. 13
Вставка
- Опубліковано 4 вер 2016
- The 13th episode of Engine Masters, presented by AMSOIL, is an unlucky one for a poor little 305ci Chevy small-block. It was the victim of our test of how much nitrous oxide power boost can be tolerated by a completely stock short-block with the original cast crank, rods, and pistons. Yeah, it ends badly, but before the engine's demise we learn a lot, showing you how nitrous oxide increases horsepower and giving you tips on how to use it safely on any engine. You'll also learn a pretty good power combo for a 305 Chevy! Engine Masters is supported by Mr. Gasket and Earl's Vapor Guard.

..now me and the mad scientist have to rip apart the block to replace the piston rings you fried
they killed marty vito!!!! XD
you got that from the fast and furious
+bryan j Jones no shit there buddy
+bryan j Jones your some special kind of stupid
+Victor Barajas (onedesire1392) really
Here we have a bone stock engine........ but.. we upgraded, this, this, this, this, this, and that...
they specifically said stock short block.
Did you even watch the video?
yes, watched the whole thing it was interesting.... 1:18 "we have hopped it up a little bit it's got..." I liked the video, I just thought it was funny that he said it was bone stock, and then detailed a few things they upgraded on it.
+jesondag those upgrades effect the horsepower and torque figures, but they don't, in any way, effect how durable it will be in nitrous.
***** it is a stock bottom end...as stated in the video...and the bottom end parts are what nitrous breaks. That's the point of this video, in case you didn't actually watch it.
"Nirous does not blow up engines. PEOPLE blow up engines."
I officially love this channel.
Motor trend does have some of the best car enthusiast shows out there
This is my favorite EM episode, I wish they would do the same test with nothing more than the stock rings gapped to .030”. With rings gapped properly, 118 gas, and the progressive controller, I bet it would safely handle a 400 shot.
I was thinking the same thing
Yea.. it's all brand new... but put a few passes on it with that kinda spray, and you will see what the rods look like hanging out the side of it.. the rod bolts won't take the stress very long and they will stretch and when that happens its Katie bar the door cause the rods are leaving home... lol
Now me and the mad scientist gotta pull apart the block, and replace the piston rings you fried!
Love that movie
dude I almost had u ....no u never had me u never had your car
i live my life a 1/4 mile at a time.
pop the hood. pop the hood? pop the hood!
2ZJ ENGINE THATS BEEN IN A FIRE? ERMAGERD!
So next episode lets see the 305 prepped for nitrous!!! Lets see what you can get out of it.
I hope so too
I agree ! Build it and see what it will take !
Maybe do a budget style build for the 305
I agree. my thoughts exactly.
Yeah that would be nice to see in the next episode but the next episode is already filmed and out... on FUCKING motortrend on demand...
I wish i could have a “junk engine” like that
305s aren't a bad engine at all. With a 3k budget a 305 is peppy .. not fast in a 3500lb street car but just a fun little efficient engine that can be had for cheap. Those heads are only like 1200 bucks.. that cam is only 279 bucks from jegs. 350 dollar intake and 500 dollar carb. That nitrous kit is the starter kit for any real racer and can be had for around 750 bucks. For under 5k you can have a reliable 450hp 305. People make fun of them but look at the abuse the Ford 302 takes..... Short stroke, big bore, same as 305. Not bad for any engine you can obtain for 350 bucks at any junkyard in the nation.
@Dave Micolichek never did I say the bores were the same.. I stated both engines work off the same principal with bore vs stroke... Junior...
Ya 305 engines are real impressive lmao🙄🙄
@Dave Micolichek umm yeah okay?? Not hard to achieve an engine like THAT?? Obviously its not hard, the O.P is talking $$ wise...
What i was thinking lol
3:27 might be the most important part of this lesson for all of the viewers that are new to motor sports
That lil 305 was making some decent power. Im sure that engine with the 150 shot would have made a decent weekend warrior setup.
No doubt...500 hp 305 could really hurt some feelings! lol
Landon I agree. 350+hp NA is stout for a 305 and over 500 on a 150 shot it gets my vote.
@@craigjohnson8217 What does the 150 in "150 shot" mean?
@@pieterveenders9793 150 hp nitrous
@@craigjohnson8217 So if I understand correctly that engine will produce an additional 150 hp when nitrous is applied, making a total of around 500 hp?
Too much Nitrous and the engine will begin to laugh.
😆
You're a diver haaaaaa
The guy that really gets to laugh is the one at the parts counter..."You're gonna need one of these, one of these, one more of these, and a whole bunch of those!!!" Parts Guys love people playing with nitrous!! ;^)
I'm a bit of a geek and have looked up tests of Amsoil against other oils, I would say that using Amsoil contributed to that engines ability to hold together as long as it did and make the power it was making.
Unfortunately it is hideously expensive here in the UK, Castrol Edge is probably the best I've used, it burned less and the engine ran better while feeling more responsive and powerful. Edge costs over twice as much as a normal fully synthetic oil but is around half the price of Amsoil.
i know a million people have said this.....so it's not stock...just pull an engine out of say a v6 camry and boost it until it explodes...don't say stock when it's not stock
When they said stock engine, they likely meant stock guts as the amount of nitrous in a V6 Camry probably couldn't handle much of anything considering it's not built for high energy output.
The bottom end, which is what nitrous breaks, is indeed stock.
@@coreyfryer2712 I don't know Toyota over build there motors the amount of power a 1uz 4.0litre V8 can handle bone stock is insane
Rewatch the beginning and you’ll catch that they said bone stock short block.
@@flubdreload2818 what they say and what they do are two different things
I was always disappointed that they didn't properly gap the rings to see how far they could really go with cast internals
With rings gapped properly, 118 gas, and the progressive controller I bet it would safely handle a 350 shot, maybe 400.
Yea but that was the point
well, since it is the expanding nitrogen that does most of the work. I.E. the burning fuel and oxigen heats the nitrogen and causes it to expand. since there are formulas to figgure out how much air you can force in with a blower, it would be close to the same, cause thats all you are realy doing with a shot of nos more oxigen and more nitrogen, same as a blower but without the moving parts.
Keep in mind, stock bottom ends don't have piston rings with extra gap for nitrous.
@@lenabeeman9041 right but If you are gonna build a cheap nitrous motor, might as well do it right
So stock BLOCK, not stock engine.
stock shortblock*
Well except for the cam... so almost stock.
exactly what i was thinking lmao just clickbait
He said short block, not engine. Pay attention and ignorance will be less of a problem.
anonymous 1:16
Come on man! Stock 305 is a honest motor that deserves respect! SBC is a tough stand up guy under the hood and this episode proves that! A Cadillac HT4100 - now that's THE BIG TIME JUNK!
I like them both. How much do you actually know about the 4100?
13:27 thank me later
Thanks
And the MVP award goes to.... @1000subsnovideos
Hero
It's people like you that make youtube a better place. Good lookin' out.
You rock my guy, thank you
Pretty impressive numbers on that stock 305...
Agreed. That was the most impressive part of the video. 358HP!! Table top flat torque curve... all with a stock short block.
Yea i was shocked when he said the numbers lol.
stock internals do not represent horsepower, just durability, the impressive numbers were because of the upgraded cam, roller rockers, vortec heads, bigger intake and an 850 double pump carb, put forged internals in the short block and it would make the same numbers. but still was impressed with 358hp and that torque curve.
jokertokerfourtwozer agree completely
jokertokerfourtwozer you do realize you just restated what he said in the video
I'm just sitting here, in Europe and the guy says "just a small Chevy engine, 3.5".
WUUUUUUUUUUUUUTTTTTTTTTTTTT, that's huge xD We drive some fucking 1.0 EcoThreePistonEngines >.>
305, as in 305ci, which is closer to 5.0L
they hilariuosly poor power for the size though.
We get big engines from euro manufacturers. You've let your governments run your lives.
You can reverse it.
billybobjoe198 That's kind of true, many people in Europe are stupid and they think that socialism/communism is the best system in the world, and the European Union began... with it's shitty rules, and tells you what your country must do. Sad.
Ahh, but Euro engines arent cast iron pushrod stuff from the 70s. They actually have some finesse
I had a high performance 305 and it was great. You can actually bolt in a 350 cam and it works great, giving you more power.
wow that's cool.
MT: "How Much Nitrous Can a Stock Engine Take?"
Me: "I don't know, BUT I KNOW HOW MUCH I'M GONNA USE!"
DANGER to manifold ... (floor panel drops)
Damn cast aluminum floor panels.
lol
shut up !!!! stage 2
I had you bro
+Ultra Sound you never had me. you never had your car
How many pulls at 600 h.p. would she have made! Now we will never know. Guess I'll have to build one now......stupid show makes me spend money, lol. Love it!
84/89 Bell-Brand
Maybe a couple hard pulls, but sooner or later that piston would've gone.
2, maybe 2 and a half passes! lol
Guess it really depends on if we're talking 1/4 or 1/8 mile? 3 to 3 1/2 in the 1/8th and prolly 1 1/2 to 2 full passes in a 1/4 if I was a gambler!! Personally, I would've stuck with the (quite impressive might I add) 150 shot at 550hp total and made 10-20 good passes and cashed in on the little 305 while gambling!! 💵😂
Oops, my bad...I jumped the gun there thinking of what I would've done versus wasting the "Little Engine that Could" on dyno pulls 🤷♂️
this "chingadera" blows up 😂
Gotta love how he bowdlerizes in English by using a Mexican Spanish curse word that every Latino instantly recognizes. Multi cultural knowledge. Now say int in Brazilian Portuguese.....Russian.......German......Arabic
#13
This show could not be any better.
You said "chingadera" and as a mexican and As a Spanish speaker I can attest and I feel obliged to say that you used the word to its fullest. I'm still laughing 🤣🤣🤣
monono monono bro I heard that and had to rewind to hear it again 😂😂
after i heard that i had a sudden urge to go to Taco Bell
@@richeyvalentine i became a taco reading this
monono monono as soon is I heard it I went straight to the comments
monono monono he’s said it for years on roadkill lol
You're lucky you didn't blow the welds on the intake

that's a good fast and the furious quote... God I love how stupid they were
Your lucky stupid isn't fatal.

They were fine. The danger to manifold light didn't come on.
I watched this 5 years after it’s first showing and it’s hilarious
Impressed by cast crank and rod strength.
"This ChinGaDERA"....CLASSIC!
always thought it was chingadera
chingadera
A wonderfully suggestive word for "thing". Safe to use at work or in the bedroom.
"Are you done playing with that chingadera?"
"I can't seem to get that chingadera to work!"
LMao i was about to say that too!
+cheeriomartinez well i been cussin in spanish since childhood and I swear its chingadera or dang been saying it wrong all my life haha

Engine Masters is without a doubt the most informative and entertaining thing I have ever come across concerning performance engines. Please keep this show alive. I enjoy it more than anything else on UA-cam by far. I fooled around installing expensive parts on piles of rusted steel and bondo starting in 1968. I ended up fading from the scene when computers come along. I guess I was intimidated Here I am at 64 years old and an old 66 Chevy II dragster fell into my lap about a month ago. A week later an L98 TPI and the rest of the drive train from an 89 pontiac Formula ended up in my ownership. I didn't plan it but now that I am slightly computer savvy I'm getting an itch!
I have an old abused 305 in my demolition derby car and that thing is an absolute animal
Next time I need a stock engine I am coming to these guys for sure.
wait can we see the dyno chart of the blow up
yeah!
I was curious of that myself!
It blew up before reaching peak hp/tq looks like. Wouldnt see anything but 400-500hp then drop off.
+Taylor Jenkins were you there?
just watch the video and pay attention dude
if nos doesn't blow up engines
people blow up engines
.
.

dose that mean toaster doesn't toast toast
toast toast toast
xD
that made my day
No, people toast toast
Actually, people toast *bread.
It isnt toast until it comes out of the toaster. :)
seems legit.
YEAH TOAST!
Thank you for creating this vid. You delivered exactly what I wanted to see.
Whenever I saw NOS it will remind me to Brian O'Connor green eclipse 😂
"Bone stock" *proceeds to point out various different aftermarket parts*
mario None of wich Will make a difference
he clearly says "bone stock short block" u prob dont know what a short block is huh lol
Bone stock short block not the cylinder heads
mario literally just commented this you beat me to it great minds think alike
This is a "bolt on" which is something added to the engine. The engine is still in its "stock" form as they didn't replace any of the internals. You can consider NOS as an air mixture
This show needs to come back to UA-cam! !
Dude, it 4.99 a month and u get all the shows
It's very useful because there had more cases about NOS Accidents【Street Racing, D1(Drift), Drag Race(0-400/0-1000)】!!
This was very impressive! I have no experience with nitrous and have never watched someone tune an engine with it. Really interesting.
I've seen things get blown on your show, I've seen Hookers get beat up badly, next think we know you guys will be PowerStroking in front of all of us. You guys need to get it together. 😜
But the Hookers at least go payed..
They weren't any less effective after the beating though.
Paid*
jonnyjb69 I wasn't talking to you, dicknose.
Lets all be nice... and pass around the Hookers.
At 6:17 when u said "chingadera", that made me crack the eff up! I was not expecting that. I enjoyed the video FYI.
I was about to write the same thing
Lol
Yeah me too I was like wtf did he just said this chingadera... he must be working with lots of raza
Lol yup got me too
Honestly
Thanks. I know nothing about cars and you explained this in a very simple way for someone like me to understand. Now feel confident putting a NOS into my VW Beetle. Bout to shame some muscle cars!
That was pretty good fellas. Fun to see that old horse blow an aneurism.
I have a crappy 305 sitting around.
This video makes me want to throw some money at it...
JeepCollector91 Not Worth It. Get A 350. i Made The 305 Mistake Once.
240mph UGR Gallardo Same. lots of money on a depressing result
I do the same thing with strippers
It's not worth it.a 350 would be better.more power.tourqe.more pulling power.305 will drink as much gas when pulling a load, often bogs down,more rpms, decrease gas mileage.the 350 with higher rpms, power will pull that load,less bogging.305 is only good for fuel economy
snoop furlow um not absolutely true
world's greatest drag race 6?
Coming soon!
+Motor Trend Channel but not until they spam it up with a commercial about how it's on no demand first.
There will be plenty of teasers for it first lol you will see them soon
+Motor Trend Channel better have the shelby gt350r and focus rs in it
So what was the dyno numbers before she suffered the melted piston blues
I’m glad I found this channel. Very helpful & very interesting!!🍻💯💯

Love learning new stuff thanks for putting this out six years ago, but I'm barely seeing it now lol
What a great video. I learning a lot about using NOS. Great job guys. Thank.....Barry
anyone else watch this just to watch an engine blowup, and was disappointed.
I wanted to see that thing turn into confetti.
And Harry, I need it by tonight
Blew up many stock engines in my life, was always disappointing... You need lots of boost to make it exciting~
Yes... but at lest no one or thing is killed
I once had a piston disintegrate, and the rod goes up and down in the cylinder until it pokes thru the side of the engine. I wanted to see something like that.
So by stock you mean not stock.
lmao
Basically . . .
He said "bone stock short block" A short block is an engine sub-assembly comprising the portion of the cylinder block below the head gasket but above the oil pan.
Actually, he said "bone stock SMALL block." The rotating components are stock in the engine which is what would typically fail on an over-nitroused engine.
No, He clearly said "Bone stock SHORT BLOCK"(and its also in the description section) which is what is effected in a nitrous application as there are rarely failures of the valve train contributed to the application of nitrous.
Really enjoy the videos, they're so well done. Thanks you.
Best episode I’ve watched yet. lol. So proud of that little 305. Good boy!!
This was actually awesome and informative. ive seen people run stock caste iron V8's on spray and they last. makes me want to run it now
Richard Arcuri
On race gas and a 250shot on a stock 355 it ran for 3yrs and only thing went wrong is my head gasket. I think it would've been good if I had head studs instead of head bolts.
lol it was informative how other than showing us that you can run nitrous on an engine upgraded for it since he was nice enough to list all the upgrades on it. Still waiting to see that "bone stock" engine he was referring to.
Always use FelPro blue head gaskets....won't blow stock or cheapies Always will
Aj Johns well the test was the bottom end
aj johns+, he didnt claim it was bone stock and no this engine is not upgraded for nitrous use. its a mild street engine that RUNS ON PUMP GAS and uses pretty much all stock parts besides the cam/lifters. Obviously you know nothing about nitrous which is ok we all gotta learn but you didnt even care to watch the video and learn anything about it either. he talks about the benefits of forged internals in the vid so whats up with that. Properly upgrading an engine for nitrous would have included forged pistons, connecting rods, and crankshaft. along with a wider than stock piston ring gap. please think before you speak. thanks.
It's funny how we car people can care so much for an engine.
We have to. Most of us ain't got money.
It's a living "thing" to us.
Being a PMD guy, Chevy is my mortal enemy, but it's still sad to see one "sent to the chair".
I only care about things that belong to me, if someone destroys an item worth thousands it don't matter. However if anything of mine, even if it's only worth a penny gets damaged I'll fucking kill whoever is responsible.
Um they care because it took money to build. Do you not care about your things that cost thousands..
Mike Morrison
I know some punk ass kids on here who do. Completely lost it when one fool in the comments below another video made the claim that a Grand for a PC is cheap.
Really awesome info and a lot of fun to watch! Thanks guys!
His face @13:11 is like “yessssss my precious, more powaaaaa”
"with this chingadera" lmao
Enrique Cruz Lmao he says that often. When I first heard it I was like wtf.
Eduardo Fraire never expected him to say "chingadera" haha hilarious
lmao mexican chingaderas
That got Me too
That was funny
Iv done this with a 350 it did really well with a 200 shot for about a year and probably ran well over a 100 bottles threw it. When I pulled it out it was still running. 😎 Great Job guys👍
GreenBoy at GA Farms you did 100 bottles of nos in a year?
@@DannySystem well there is 365 days in a year and I was a avid Street racer so yeah it's not hard to go through a Hundred Bottles if you spray a lot
@@DannySystem that's a rough idea also so roughly A Hundred Bottles if he did the math it was probably more like 95 92 96 somewhere in that area still I ran a shitload of nitrous through it.
The funniest, and ironic thing about this whole video was him saying "Dont call it NOS/NOZ, cause that's a rookie movie" and 30 seconds later a commercial for NOS comes on and thats exactly what the guy in the commerical called it. 🤣🤣🤣
Surprising!!! Im pretty amazed at what it held up to
13:48 that piano track made me tear up a little..
I think that's "When Everything Dies" by God is an Astronaught
WOW free Motortrend content ? WTF?

Well it was obviously sponsored !
Thank you for the class. Great video. Keep up the grate work.
This is an excellent video. Thank you for the great topic.
I really don't understand the hate given towards 305 SBC's, they run smooth, can produce a decent amount of power even if it's a little low, but the real talents are how much fuel economy and mileage 305 cast iron small blocks are blessed with. 263,000 miles on my '92 Camaro's bone stock 305, runs like it's brand new, just warm her up a little and she's ready to rip!
..thats all a joke right? decent power, fuel economy, runs like new after warming up...That thing is only getting good fuel economy if you are comparing it to a say a 74 deville...
Those and the 307 have always been boat anchors, I'm impressed that it made that much power on it's own, as well as took the lower levels of nitrous........as well as how much money and what parts they dumped into it before it blew!
well.....it's because they're turds. They weren't even up to the task when they were new, as anybody with a 5.0 Ford of the same era would have demonstrated to you at every available opportunity.
You didn't even need a 5.0 Mustang, I could take them down with a 4dr Hatch Lebaron with their early 2.2l Turbo 4 that only good for just shy of 150hp.
GreenJeep1998 True. Those turbo Mopars were nasty little sleepers.
I find it funny that on the 13th episode, you guys kill an engine.

Very informative channel. Great job guys👌🏻👌🏻👌🏻
I like the production of the video. It legitimately felt like a TV show or something. You guys also are very user friendly most, if not all, of the terms you used to describe things was simple and not stand-offish. Yeah sure idk what some of the things in the engine were that you upgraded but for the most part you were very user friendly. Are you a shop professor ? Lol
They sell energy drinks that big?!
Steve-O’s favorite
Lol
A lot to comment on here, but pulling the engine apart and adding turbo pistons, main and head studs with HP valve springs and better head gaskets would give this little hot rod some life on the street with around 600 hp. Great video, looks like fun for sure
Probably my favorite episode!
i dont know about a short block, but my h22a took over a 100 dry shot every friday night for over a year.
Dry lol doesn't count
@@boostjunkie2320 its still a shot fam, technically, it does...
Just like my wife
How does dry not count ? That’s harder than a wet hit
I woulda killed for that 305
Orlando Aspericueta buy one
You need a better paying job then.
Then you need to raise your standards lol
Killed what?
This particular 305 was quite impressive (for what it is) but you'd be insane to spend a single dime really trying to build one. Hence the reason they grenaded this one instead of a 350!
That hand held controller is GODHEAD !
Thank you so much for what you do, David
The fast and furious has a red button to push. Movies are real.
Good God, you mean the same 1st movie that made under glow and body kits "Cool"? lol
+Jackie chan_WTF i wish they didnt... Ricers are annoying
Ricers are just about gone now.
It was a quick rise and fall of them, I knew that back when that BS started, no way was this going to "trend" for long.
This "trend" is here to stay, I'm afraid because rice appeals to the stupid and there has always been plenty of those around.
I still see ricers on the streets. Maybe not as many of them as in the early 2000s but they are around.
I just think that movie is funny. Because they are seen to be the best of the best street racers. Yet their cars are only running 10 second 1/4s...... And his Rx7 is like the unbeatable car when 10 second rx7s are sooooooo common.
So it's salvageable? Guess that means a revisit with built bottom end.
I want a budget NOS build!
This WAS the budget NOS build.
+cracklingice no it wasn't, they said this was a stock engine not meant for NOS at all.
Short block does not equal budget build. Therefore this was the budget build.
And it wasn't a stock engine, it was just a stock short block. The cam and short block up are all aftermarket.

You should consider this one fact we got our love for this guy from road kill speaking to his success before today and which brings him into destiny before our tread
"Completely Stock"
...Continues to list like 30 mods...
intake,carb,cam and vortec heads. that's 4. you can't count
Reminds me of my co-worker saying he had a "Stock" Firebird with full bolt-ons and $2,000 in suspension bits. lol
And heads, intake, carb, cam, balancer etc.
the only changes were the heads,cam, intake and carb. the short block is stock. these are typical changes. i would even say the heads are stock since they are vortec castings.
It is still basically stock my good man...completely stock short block with stock Chevrolet heads decent cam and intake isn't very much. The point of the video is how much a stock bottom end can take, period. Point well proven!
Wow that was Awesome Guys .. I own a 305ci and was good to see how much Power stock mod set up . and Really interesting on No2 .. Over 600hp amazing ..
You guys make the absolute best videos
225k miles Honda V6 J-Series J30A5 Engine, ran 100k miles on 100 shot, 30+ 10lb bottle and never an issue! Tune it Right, set it up right and you'll never have issues. Only issue, finding a place to fill the bottle
Revisit this and add upgraded pistons/rings only and go full send on a 2 shot...Ramp it up 30%~75% over 3 seconds and bet you hit 800. If it survives, go full 50%~100% and tickle 900 and make a 4 piece crank 😂
😂😂😂😂

they'll just make you pay for motor trend to see it or give you commercials every 30 seconds

🤣😂👍🏼
Hurt it real good...
I'd like to see what 305 with forged pistons with proper ring gaps, good rods, cast crank and those new edelbrock 305 heads can do.
I want a little 305 like that! I was impressed by the power it made even without nitrous. But I think the 150 shot was a great match for it. Makes me want to build it one! I have a friend with an old S10 I could throw it in.
I love all testing this channel provided 💌
You should do a video of how much horsepower ur car losses over time, say like when u buy a new car it has 700hp and 9 years later how much horsepower do u have still, what can 9 or so years do to ur hp rating
Well one huge figured difference between a motor loosing horsepower and a car losing horsepower is that the motor's energy is being pushed through a transmission, and axles, and wheels. The other parts that stop rolling so nicely tend to fight the motor and cause it to break down faster. Bearings start losing polish, cams start getting a little flat, wires corrode, rings thin... Eventually the parts that solidly transfered energy from the piston head to the rear wheels get so much slop that the power actually ends up working at breaking parts down till they just don't work no more.
My 92 explorer used to get 17mpg, now it's down to 12 and the radiator leaks. But the ac works great!
Or you could just do a compression test and compare it to factory which would show you how bad valves, cam and rings are wearing.
I don't think you caught the drift of what I was saying, the comment was more of an answer as to why vehicles lose horsepower over time. As for your comment, a compression test does nothing but show compression, doesn't tell you if a valve is stuck open or of a gasket blown or a piston melted through. No way could it give you an idea of the nature of several components in a system as far as wear goes. I also fail to see any linkage between a cam being flat and compression. Unless of course your talking about an exhaust valve not lifting, and giving too much compression. But that would be cam failure, and even then that could be valve failure, or blockage, so yeah... Compression is just compression..
I answered your question precisely. Not my fault you can't grasp it.
I am pretty sure a compression test can tell you if a valve is open, blown gasket, or a melted piston because if you had any of these you would not have compression.. right? And if your intake valves aren't opening enough or at all to let air in because you have a wiped lobe you will have 0 compression. Compression tests are one of the most helpful of diagnostics you can do .
