- WHAT IS THE BEST WAY TO MAKE POWER WITH YOUR 4.6L OR 5.4L 2-VALVE FORD? EASY, JUST ADD BOOST, BUT WHAT KIND OF BOOST? WHAT MAKLE MORE POWER, A VORTECH CENTRIFUGAL SUPERCHARGER OR A KENNE BELL TWIN-SCREW SUPERCHARGER? HOW MUCH BOOST CAN I RUN? HOW MUCH POWER CAN I MAKE? WILL MY 4.6L MOTOR BREAK? WHAT CAMS SHOULD I RUN FOR BOOST? WILL PORTED CYLINDER HEADS HELP? CHECK OUT THIS VIDEO WHERE I COVER THE NA BUILD UP OF THE 1998 NON-PI MOTOR WITH PORTED PI HEADS, COMP CAMS AND A PI INTAKE, THE ADD BOOST FROM A KENN BELL TWIN-SCREW BLOWER AND FROM A VORTECH CENTRIFUGAL SUPERCHARGER. WHICH WOULD YOU CHOOSE?
The legend himself makes a 2v video in 2023 what a guy
I'm a loyal 2v guy n yes, he's the man.. Not many ppl care to build a 2v anymore, fuck them..
@@P71ScrewHeadYea, I think I'm going to go with the vortech supercharger.
@@hotrodlincoln7186 Gonna be a fun car.. Let me know how it goes..
@@P71ScrewHead will do
Just need to save up for the build
@@P71ScrewHead I want at least 500 to 600 to the wheel and 450 to 550 for tq
I always liked roots/twin screw blowers. Instant power and linear power band.
The vortech would be good on a stroker motor since it would already have good low end torque, Root style on a small cuin motor to make up for the lower torque curve.
Slip a ice water to air intercooler between the Kenne bell supercharger and watch the magic happen ;)
And I'd choose the Kenne bell supercharger on the street..especially since my car is kinda heavy.
I installed the vortech supercharger on my 99 gt with a bunch of other mods and I was very happy with it! After a little while I went to a 3.33 pulley and 42 lb injectors and it went from about 8 lbs to 12 lbs of boost but racing is a bad addiction because no matter how fast your car is you always want it to be faster. I was so happy when I was running 13s with just a few bolt ons then I was happy when I broke into the 12s and then I was happy when I broke into the 11s..... you get the point, it's never enough
It’s cool how that twin screw makes that 281 act like a big motor! It’s hard to make that sweet low end torque!
Yeah ≈480 lb⋅ft of torque at ≈2500 rpm is pretty nice
I’d definitely like to see more tests on the 4.6 4V! Such as header comparisons, different cam setups, etc. Great videos as always, Richard!
Torque please. , low. Pavement cracking torque please. Kenne bell
I like the.KB power curve best. Unless I missed something this a stock bottom end correct? I already have drag radicals so, the traction with.the.torque numbers could managed? Excellent work!! Thank you!
stock 1998 bottom end
I love turbos and how the power comes on and how they drive, but the on demand tq from that KB has to be extreemly fun and impressive feeling.
Oh, I'm bias'd on this one. I still have KB, in Rancho Cucamonga, on my speed dial.
Kenne Bell for drag.
NA for daily or rally.
Vortech for anything else.
That rising torque curve would hook up so good coming out of a tight corner on the touge. Unwind the steering as the revs rise and just slingshot out of there. Superbikes do that all the time - use the lack of low-end to gain control on the side of the tire and then ride the wave as you straighten out. That kind of thing becomes important with 600+ hp and RWD. A PD blower or pair of turbos could really blow the tires off at the apex.
Never could understand why anyone would run a centrifugal blower. Why would you not want a big, flat torque curve?
They must live at 8k rpm..lol No way i'd ever prefer a snail over a pd blower, never been a turbo person either..
I have a kenne bell 3.6 liter on my Pontiac g8. Picking it up next week to take it and get tuned. Can’t wait. Only g8 out that I know of with a kenne bell.
Really depends I’m usually deciding on how to build power while considering the purpose of the build. A lot depends like the rest of car combo but let’s give it a shot.
Street- screw blower, man trans, 3.55:1’s
Track- centri, auto 3 spd,5000 rpm stall, 4.11:1-4.56
I still like the screw the truck would only win at the track maybe. There’s actually a huge
Disparity in the power in the screw blowers favor even though the centri peaks higher. If they were both e85 (pump gas) then the screw would probably be safe on even real hot days. It’s very hard to beat the screw blower on this one.
For the track a centrifugal makes the most sense because you're gearing the car to stay in the higher (peak) power band.
Either way, Vortech and KB really are street use brands.
Kenne Bell 100% .. I daily drive, so all that torque down there below 5000 rpm would be too fun on the surface roads (and getting on the freeway) .. Just go turbo if you want a vortech ..
The appeal of a KB or Vortech kit is the ease of installation and readily available parts (kinda....KB is weird with "parts")
I dont know shredding tires doesn't sound like a daily driver activity
@@WarriorOfEden3033 Self control saves tires :) ..
@@67comet have you seen the car community 😂 what’s the point of having it if you aren’t using it
In this case, Kenne Belle street car but there are versions of that that essentially push so much air that you're basically making a V8 into a V8 with a V8 on top... It also depends on whether you drag race from a dig or drag race at like 60 miles an hour...
YAY 2v LOVE! Always a great day when we get a 2V video!
A blower that comes on with boost at the top end would make it easier to launch. You also tend to suprize the competition coming up on them at end of the run. On the street the screw type just sounds cooler and a harder launch looks impressive.
Very true. Stickier tires alleviate that problem.
If the redline was something like 7200rpm, what would the difference in power/torque be?
I have a thick Crown Vic with a very healthy 2v at 79k original miles. I was planning on using it to build a 600hp - 800hp setup. The KB would be nice for low end torque, but the VT seems to be able to produce more peak hp. If I'm being honest, I get goofy over that KB whine.
PD blower hands down on a street car, ESPECIALLY with a heavy basterd like a Vic!
Also taller gears help get the two and half tons of fun out of the gate a bit better!
(I have a Vic with 4.10s and a manual trans.... Faster with the auto but so much more fun with the stick! .... I have a KB kit and other goodies sitting around for it but current project is the suspension and audio portion 😏)
Oh and it really doesn't matter how healthy the current engine is, when you're looking at 600+ hp then you need to build a lower end anyway!
Also the KB also takes care of the intake manifold issue with 2v's when looking at that power level considering there isn't much out there and what is, is ridiculously priced!
Then comes the heads which honestly if you want to keep it "budget" then rods and pistons, 4v head swap and turbo would be the way to go! Then your limiting factor becomes the transmission!
600+ HP isn't as cheap as people seem to think, just in hardware I had over a grand alone! It is much cheaper nowadays with the flood of Chinese products being readily available (for instance turbos, an line and fittings, tools to fabricate, etc...... )
I've always wanted a KB for my 04 gt. What size is this blower? Is it the 2.1 liter?
I’ll take torque all day if we are talking drag racing. You will be ahead in the 1/8 and hold that lead through the 1/4
Can you not buy kenne bell superchargers anymore for the 4.6
I would take the Kenne Bell setup given these two options. Street and track.
My nigga!! (in Denzel Washington voice..lol) i too prefer the pd blower for any case, fuck traction..
I've always felt that when comparing forced induction a centrifugal supercharger takes all the disadvantages of supercharging and turbocharging and puts it all in one neat package.
What if the vehicle already has traction issues? Something to think about.
@DillonAuto then you need to upgrade your suspension
Yes and no, in a street car the linear power curve of the centrifugal is actually really nice in terms of giving you nice usable power delivery, and the way that blower just keeps on building as the revs increase is actually very potent when racing, especially from a roll
What's the disadvantages of turbo that a centrifugal makes up for?
TFS needs to give you a set of Twisted Wedge for modular. Be nice test with Ford Racing 5.3 stroker short block.
Why use a Vortech when a turbo will have the same shape power curve without the parasitic loss. I'll take the instant torque all day long from the supercharger.
Because the vortech is a cheaper, easier set it and forget it setup.
KB all day. Better average numbers and sound is unrivaled.
No comparison, Kenne Bell averages more hp and torque than the Vortech,
Id take the kenny bell all day, that 20hp isn't worth all that torque
I auto cross and I would go with the Kennebell for the torque curve
Do you use the 8 thread spark plug heads Richard or? Have you ever blew the spark plugs out on the 4 thread heads.?
I just picked up a Vortech innerccoled kit for a 10th gen f150..VERY HARD TO FIND!
I have not blown plugs out
Centrifugal blowers are way more drivetrain friendly. Twin screws give you all that low end but tear things up so much faster. Throw a set of gears in the back and just get to that power band a little faster!
When you swapped cams in this 2v did you just put them in as / is, or did you degree them in with adjustable cam sprockets. Pretty amazing difference going from the Comp cams back to the truck cams with boost from the centrifugal
just installed the cams-later we degreed
I think you should do a China copy cam video. Do like four of them. The reason I say this is I have one and it runs pretty good. I thought I was ordering an Elgin. All through the ad it said Elgin. Then at the end, after I ordered, in tiny print, it said the dreaded three words…”made in China”.
Well, I’m a single dad so no money to swap this out so I gotta run it. I did, and it does make good power and sound good.
My question is, material longevity, and accuracy of grind, and probably most important is how does it affect performance.
Anyway, haven’t ever seen you do a China copy mistake purchase video.
Maybe I missed it.
Love your stuff, hope all is well.
I had an 02 gt with ported trickflow heads, comp stage 2 cams(don't ask me specs because I have no idea anymore), jessel folowers (those mf'rs were like $100 each) BBK long tubes, dual gt supercharger pumps, and a vortech v2 with a billet impeller upgrade made by some company (supposedly when spun harder would outflow a t trim) even after I put the nitto drag radials on I barely got traction after I heatedthe tires up. I can only imagine how terrible it would have been with the Kenne Belle with all the extra low speed torque. The centrifugal setup is definitely the way to go. All the horsepower in the world does you no good if you can't transplant it to the ground.
Tire bro, you need a sick grippy tire.. i personally prefer all the torque for a street car, centri for a drag car, but i've never been a fan of the centri..
@P71ScrewHead when i used to run a centri blower i could still blow mickey Thompson rock throwers off the car with a vortech.. the kenne bell would have been a headache to be honest. I ran 9 lbs centri and cams with 4.10s and put a bus length on my buddies 12 lb kenne bell with 3.27s
@@01Snorky that math isn't mathing......
You're talking same cars but the supercharger style and gears were the only difference?
Obviously the other difference is driver and evidently your buddy can't drive worth a 💩! He should have waxed you all day!
Just bought a kenne bell I wanted to have the super charger whine.
I’d say going with a procharger/Vortech/Paxton would be easier for a daily, I have a v1 s trim on my 2002 mustang GT, intercooled, not water cooled or after cooled however they say it, but I would say for fuel economy, centrifugal all the way.
That kb would be a monster anytime you hit the throttle. Who would not live that!
Twin screw rules....from someone who's used em all. I have direct comparison on two S197s with Coyote. The VorPax was great to install but, the car felt like a slightly soggy stocker running around and you needed to wring its neck to get anything out of it. The 2.3 TVS on a mild tune just rips everywhere and helps cut the 60 foot at the track, too. Just gotta mind keeping it cool between runs. That installation was WAY more complex than VorPax, to be honest. I'd add I chased false knock for a good while tuning the VorPax, no such issues with the TVS. I'll also add that the 2.3 TVS adds more weight to the car but, makes more than enough to compensate, My loaded automatic 2014 weighs in at just under 4000 pounds with me in it and a tank of gas. runs 121 mph in the 1/4 on 8 pounds boost. Obviously not tuned max but, runs pump 91 no problem and is lots of fun.
Without knowing the cost your questions are not easy to answer.
Twin screw all day every day on the street or strip.
either boost gadget would be fine with me ill leave it to you to install it in my 911 tho lmao
PD all the way. More power under the curve.
Positive Displacement all day.
What size injectors do I need for a 1000 horsepower on 06 4.8, and who makes a reliable injector?
80 pounds will just get you there on gas, you need 100+ pounders for e85
Kenny bell
Kenne Bell all the way. The lower HP and torque at the higher RPM's is worth the difference on the bottom end. I have an Edelbrock E-Force on my 3V Mustang, and love the instance torque when I stab the throttle. It doesn't matter what RPM you happen to have the motor at, it always happens.
Kenny Bell for the Win! Awesome Video Richard! Thanks!
Twin screw for good short track times on drag car with prep surface. Vortec street car possibly less likely to brake traction on the low end, maybe a slightly better mpg when not on full throttle.
Belt driven turbo superchargers are only good if you want easy. Actual superchargers and turbos are better
superchargers are usually belt driven
Thanks for the 2v love!
Street car , Kenny bell all the way , can’t beat that twin screw wine at wide open throttle
does anyone think a centrifugal S/C will be more forgiving on a driveline opposed to a top mount S/C? even if theyre similar peak power?
On a stock motor, torque kills em, so i've heard..
KeeneBell all day. I want that low end power to get things moving.
I would take the Kenne Bell because I like that flat torque curve.
I swapped from a Vortech Non intercooled blower to a zex wet setup and was super happy.
Kenne hands down.......IMO.
KB all day
That low end torque on a street strip car would eat the Vortec for lunch, especially in a light to light scenario, or 1/8th mile. The Kenne Bell on a truck that's pulling something might need a water/methanol system. In a light car with low gears, the Vortec might work ok, but it's all going to come down to setup. Just wondering how long a 281" motor holds it's guts at 500+ hp and torque.
Another killer video! Really appreciate the time spent on the camshaft comparisons too. Especially on these motors -- double the aggravation. Lol
Kenne Bell all day.
The twin screw operates kind of like turbo with electronic boost control and the huge difference in area under the curves is hard to ignore. It will not make as much power as turbo with same boost due to supercharge losses but it is a really good choice when under hood packaging is a factor. For every day driving, I have always liked centrifugal and roots style superchargers. It is not easy to put an instant 500lb/ft of torque to the ground. T-5s will also hold up under that level power (in daily driving) behind a centirfugal or roots supercharger but kind of sketchy with a turbo or Kenne Bell.
Think that's the first time I've heard a PD blower operates like a turbo (considering a centrifugal is literally a belt driven turbo....)
"It will not make as much power... with the same boost"
That's not how it works! It's also too vague.
You say that it will hold up to a "roots" but not a "Kenne Bell"? Roots is a PD supercharger just the same as a KB..... Also a PD supercharger is harder on a transmissions than turbo for sure!
Stop putting drop-down menus over the power curves and it won't be hard to discern at all. O_o
Hard to argue all that torque
I'm running a kenne bell on my cobra
I love Kenny bell, but that company is practically dead. They’re not innovating anymore. They barely answer the phone. Covid shut them down for months. Mike seemed like the only good thing there.
they are coming back
@@richardholdener1727bring on the TwinScrew wars! Whipple vs KB! I’m all for some healthy competition 😄👍
I'm still waiting for roots blower with a clutch like Mad Max had...
That's been done. The Mercedes M271 had an electromagnetic clutch to stop the Eaton blower from turning when boost was not demanded. Plus, the Eaton blower had a bypass valve.
@@andyharman3022 Not sure it's trivial for a electro clutch to hold an over 100hp load?
The Mercedes 55 AMGs have a clutched pulley but I guess technically that doesn't count because they are twin screw and not roots.
@@theinsaneshecklador6598 I went down the "rabbit hole" before searching for higher power electro clutches before and couldn't find much. Let me know if you figure it out. Would be ultimate cool with on demand supercharging and bypass.
@@theinsaneshecklador6598 Screw compressors and Roots blowers are both positive-displacement machines.
Lightning motor 5.4 Kenny Bell 2.3 chassis Dyno. Race? Gas around 19 lb of boost. 500 horsepower 605 lb of torque.👍
PD on a street car and Centrifugal on a strip car hands down!
HOWEVER Whipple is starting to change the game on modern engines!
I'd go the KB every day. It drops the torque in the sweet spot. 👍🇭🇲
Whipple has the 2.9 out for the 5.4 2V with the 01-04 Lightning intake manifold and I/C. 6-700 RWTQ on 93 pump
Kenne Bell torque curve is flatter than flat! Impressive!
I own a 2002 C5 corvette manual. It was previously owned by a employee at Kenne Bell. Love this car its a torque monster. It also has 243 heads, a mild comp cam and 90mm T body. 600 plus at the wheels on 93. Yaaaaaaaaa
I would say at first I'd go with the kennebell.
But, more than likely, I'd go with the vortech. For a few reasons.
1. Like you mentioned, the traction. You see all that tq is going to be putting alot of abuse on your rear-end. Plus, not only that, if you don't have traction, you ain't going no were.
2. Vortech tends not to overheat as much as a kenne bell would.
3. Unless it's going to be a track only car, then yea the kenne all day.
But, if it's a daily, then the vortech is better. It's better because you can have just a regular car when just daily driving it normally, but when you want that power, it's there.
4. The amount of gas you're going to be spending with a kennebell supercharger. I've seen some videos on here where you will only be getting 8mpg 10mpg if you baby it. You see with a vortech supercharger as long as you drive normal it's never in boost, and if it's not in boost, then it's not being so hard on your gas.
5. Oh, and for all those that say well the vortech takes longer to rev up in rpms. Well, I got something for that. It's called jmschip by pedalmax. The jmschip does not mess with any tunes, nor is a tune required. Basically, what it does is depending on how you have the dial set on. But like with me, I tend to have mine between 75% and 100%, and man, you barely have to tap the gas, and it just goes. It even down shifts easily even if you're already doing like 75mph. Just look at my videos and see for yourself.
Oh by the way the website is called
www.Jmschip.com
Just sure you choose the pedalmax option as they have many options.
I want the KB for my street car for sure! At the track I’d take the Vortech. Great video!
I had the vortecc with the vortech intercooler system on my 02. 4:10s plus more other stuff than I care to remember made 450 rear wheel…. I had subframe connectors and a lot of maximum Motorsports H&R and tokico suspension parts, and 03 Cobra Brakes. 450 rear wheel doesn’t sound like a lot, but when you can rip around the streets on a car that stops and turns on a dime much more power wouldn’t have helped the car…. It never broke, EVER!! I could drive thousands of miles at a time with the AC blowing and it would run and drive like stock.
On that note, I’d try the Kenny Bell to replace that junk plastic intake and to keep the battery under the hood.
yes big bang 2v!!!! lets do it!!!
Let's do it then!! I'm actually attempting to do that on my 09 P71..
I think packaging makes a big difference ,for as much room the centrifugal takes up you could do a single turbo set up and make more power
The single turbo kit is far more cramped.. the centri blower has all the room in the world to play with it. Single turbo.. not so much
@RAllen then your a garbage fabricator
@@01Snorkytrue but that single turbo is half the price.
If someone gave me a 4.6l 2v for my bucket I would have to go with the Roots style blower over the gutless at low RPM centrifugal blower, because what I use the bucket for rewards a flat torque curve and instant throttle response over peak power at high RPM.
Commenting before watching. I currently have a vortech and considering a 2.1 and I come across this video.. cant wait!
I would of liked to know boost temps after some runs kenne is known to be hotter after a few runs remember low speed torque is for first gear after that you don’t drop very low so hp is your friend
a twin screw is actually much better for parasitic loss and air temp than a roots
I think vortech superchargers are better for traction limited cars like fwd Hondas. At this point, it's about putting the power down. Most car that are not awd simply can't handle huge power without slicks.
Rather have the torque down low for the track, 3000 converter
What a nugget of a motor…
Wondering out loud here, what will some pulley swapping on the Kenne Bell do for this combo? Got any guesses? Great video! Now I know what to look for during the junkyard crawl. Keep 'em coming!
more blower speed equals more power-e85 would help
I'd go KB for everything. That torque difference is way too big.
I don't think it was valve float. The kenne bell run was continuing to gain at 6500 with the same springs. Seems to be a fuel issue but I wasn't in the cell that day so...
twin screw.... : )
Great video boss! I want a Kenne Bell next year for sure! Gotta get the cams and heads and long tubes first. Thanks for the video!
Also about the power jump anomaly on the 2.2 dodge. I think the exhaust was 2 big. Just has to have a certain velocity before it will start scavenging
MOD MOTOR CONTENNNNNTTTTTTTT!!!!!!!!!!
30 seconds into the video, twin screw fro both scenarios. Not necessarily the Ken belle in the video
Love the 2v stuff thank you
It is interesting to compare this against the terminator you tested in June 2021. Which costs less? Which weighs less?
yay mod motor
RPM wise
PD for the street , Vortec for Race only. before.
PD for street PD for racing too , methanol , bigger lower pulley & smaller top puilley to race.
Lots of mods available to put the m112 on the 3.8l. I’d love to see this testing on the v6. There’s just not near enough information out there.
