- HOW CAN I ADD 100+HP TO MY SUPERCHARGED LS? SHOULD I RUN AN INTERCOOLER ON MY SUPERCHARGED LS? HOW MUCH POWER IS AN INTERCOOLER WORTH? HOW MUCH POWER IS E85 WORTH? HOW MUCH POWER IS A CAM SWAP WORTH ON A SUPERCHARGED LS? HOW WELL DOES THE FACTORY LS9 CAM WORK UNDER BOOST? IS THERE A BETTER SUPERCHARGED CAM THAN THE FACTORY LS9? HOW MUCH POWER IS A VORTECH SUPERCHARGER WORTH? CHECK OUT THIS VIDEO WHERE I RAN A 5.3L LS TRUCK MOTOR FIRST NATURALLY ASPIRATED WITH A FACTORY LS9 CAM. I THEN ADDED A VORTECH SUPERCHARGER. THIS VIDEO IS ABOUT HOW I INCREASED THE POWER OUTPUT OF THE ALREADY SUPERCHARGED 5.3L BY OVER 100 HP, ALL WITHOUT RESORTING TO INCREASING THE BOOST WITH A PULLEY CHANGE!

That's what I'm talking about making HP with making more boost....that's hot rod stuff. Thanks Richard.
I’m going way out in left field here. I realize Chevy is king, do you ever Dyno any old school Mopar stuff? I would love to see an honest ol school 70 426 Hemi 425hp engine build and Dyno. This way you can control all aspects like you do with your regular builds. No BS, build a stock replica 426 HEMI from 1970 as te The factory would have built and Dyno it. Too many way over exaggerated numbers in typical Dyno utube exaggeration. This is why I watch your videos, no BS, real results.
Ran this back and forth through my head Mr Holdener. Hp and TQ increased, so mass air flow had to increase given the fixed blower ratio. My theory will be that gauge pressure(boost) increased because of reversion/overlap/ fighting intake pressure with the 222/244 cam
Man I got a new phone and it logged me into an old UA-cam account. It wasn’t subscribed to your channel. Was just thinking where has Richard been. Lucky for me I get to binge some fresh content.
The lobe separation on the blower cam was the reason for increase power and boost.
Very cool as usual, thank you! turbo magnum! turbo magnum! turbo magnum!
Based on the theory that no pump ever delivers pressure, only flow and you only get pressure if you introduce a restriction to that flow; the BTR inlet lobe must have less area under the curve than the LS9 profile, but makes the extra power on the exhaust side by reducing pumping losses.
PD blowers deliver flow, centrifugal air pumps (whatever the power source) care a lot about pressure - they will deliver more air if pressure is reduced.
Maybe with the upgraded cam and more air flow, the compressor operated at it's more effective region.
Predator is here.
Guess BTR has been watching your videos to prove you wrong and produce a real blower cam! lol
I’m thinking the cam had the proper over lap along with valve timing and it wasn’t bleeding off boost.
I totally expected the boost to drop about 1psi based on some of your previous tests. Maybe BTR pulled a rabbit out of their hat?
Question on head gaskets.... 6.0 liter LS for example... head gaskets are avail with various bore diameters. You can get MLS type gaskets at 4.100 bore or 4.200 bore etc etc. Should you always choose a gasket closest to the actual bore size? Does it matter that much?
4.100 for a 6.0l
Richard I would like to see you so some ls stock intake and nitrous setups
For ls engines
lots of nitrous videos up with stock intakes
This is cool. A lot of work. Very expensive. So I gotta stick with the easy and cheaper version of the 100 shot of NOS.
As far as the cams go ... is that not just open and closing timing of the valves?
I bet you know the answer. LOL
Now for the magic question, where does the reliability start to be affected? With being a daily driver around town and occasional strip trip, how will the aluminum block late model LS 5.3 hold up? I want to go with good heads, valvetrain, cam and Procharger on my 2022 Z71 5.3. Where will the power be and will the transmission hold up also?
the 5.3l alum block has been run over 1500 hp
OMG , Richard said choose the right cam . . . . . . .
and yet
Richard, this is a little off-topic, but are you ever going to do the retest on the L78 Chevy? If yes, when? Me and a lot of people out there are still interested.
YES
How to add 250 horsepower with no extra boost? 🤔 easy nitro methane 🔥🔥
I would think the engine became more efficent over the cam swap. And it is a no brainer on cooler air always makes more power. But i cant help to wonder if the timing was left at 21 then ran and bump to 23 what was the hp per timing increase. I mean yes you want to take adavantge of the cooler air and better fuel but how much did timing contribute?
Also we just did a ls 6.0 turbo motor nothing fancy ring gap gen 4 rods. nice cam btr intake. In the car with out the turbo hooked up, running through foward facing mainfolds. th400 3200 stall 3.90 gear promax 245 heads e85. made 458 to the wheels at max 28* afr mid 11 e85 scale. Im wondering this the motor didnt make any more power na so is it safe to say its a 450 hp motor ? Im thinking once i put the 98mm turbo on and run it up to atmospheric pressure 14.5 psi will it almost double in hp? I mean im not changing the tune at all as far as timing , afr might need adjusting but other than that nothing else i should make 900 hp or close to it at just 1 bar 14,5 psi right?
as always richard great info great vid learning alot finally catching up on the vids i dident see.
on e95 with an intercooler and a good exhaust-it should double at 14.7 psi
Richard, is that the eBay Vortech/Powerdyne bracket?! I am currently putting together a very similar setup using that bracket and having trouble figuring out what to use for the lower idler pulley. I pictured exactly what you have done, but unsure what idler to buy
we used a Vortech bracket from Vortech
Can we get a Howard's Rattler cam test?
Great video, I would have like to have seen what the increase would be of just doing the E85 would have been then the intercooler, in the sequence that you did them in they produced similar gains, do you think the E85 would have shown a larger gain if done first?
Richard, i have a quick question did you ever run into the issue of blowing the belt off on this set up? I had one on my truck and could not keep the belt on at high rpm.
never had a belt come off, but did have slippage at high rpm
I have a 2005 Chevrolet Silverado with a 5.3 Would it be possible to run this supercharger On stock heads and stock Bottom end and with stock injectors Or would it be better to upgrade the injectors to the £80 injectors , And where can I get this setup and does it come complete with everything in the kit To do the changes ?
You could definitely run everything here on a stock engine, BUT definitely not with stock injectors. Not safely anyway. The pwm would be beyond maxed out and idk if that would even work, so like I said, not safely. You'd just need everything here, and injectors and a VERY GOOD TUNE. Your weak points of course are going to be the pistons/ring gap, then pins/rods. If you kept it turned moderately down on a lower boost level like this it would run on a good tune for a long time if it wasn't abused.
Can you please do a ls 5.3 compound turbo build 64mm over 88 or 90 mm??
see the compound ls videos-but it is not those two turbos-just what I had laying around
E85 is the wonder fuel for boost.
@@DillonAuto Compromise is always a consideration. Building a pump gas freindly turbo rig is a compromise in ultimate output on a power per dollar basis, with the trade off being fuel up anywhere. But if E85 exists nearby, or you have a flex fuel sensor, and enough injector, E85 offers cooler, slower burning fuel mixtures, which allow more aggressive timing, and more power, and E85 is 2.85 a gallon by me, now you use 30%+ more because it has less energy density, but it's under $3 a gallon.
@@jamesgeorge4874 You're way off where I was going. E85 has a very low BTU output compared to gas. I'm guessing didn't use C16 because many can't get their hands on it and wanted to show another way.
@@DillonAuto I have no idea what you are rambling about, I do know how to make more power with boost , and E85, because I've done it, and Richard has proven it, (right here, in fact !) I don't understand why you're arguing with _results posted in this video_ bro, *they speak for themselves* ........
@@DillonAuto This whole vid is about making more power, with boost, and how E85 makes bigger numbers, than pump gas, and absolutely I understand how it works, *I HAVE DONE IT* !!! Boost my freind. Boost. This is a video about boost. I said E85 is the wonder fuel for boost. You are rambling on about "I said nothing about boost" well, I did.........bye now.
The BTR cam you said was a blower cam? If memory serves, aren’t blower cams reduced overlap?
Less overlap and early ex valve opening, I would think.
the cam specs were provided-use them and go to summit racing cam calculator
woodpecker is right
Watch out scat packs and he’ll kittys 😂
Nah
@@vortech3453exactly lol there easy work
Most, definitely not all, I see or run into around my area are 100% stock, except maybe a catback. And beat on and treated like crap. Typically with bald stock tires, and a moronic driver. It's the quiet ones with their windows up that I worry about lol. I'm about to do two cam swaps for a coworker (scared to work on his own car 🤷🏼♂️) on his Cat and his wife's 5.7 Durango and it's taken everything I have to not smack him trying to explain camshafts and getting one (for both vehicles) that are actually drivable and usable. Meanwhile the tires are 5yo and hardly any tread, stock gear, no converter, stock ds, and he wants me to pull the blower and go TT or one big single.....
Where can I find the mounting bracket for my vortech supercharger to fit on my 5.3 vortec
from Vortech
Back to the start, an engine should have the proper opening and closing points
Put a m90 on a 4.3
It was breathing better, boost went down, and hp went up.
boost went up and power went up with the cam swap
Less overlap??? Must have missed that...
Exhaust duration ?
BT Camshaft has bigger lift and more duration.
Whats a good 6.0 cam ? I have a sloppy mechanics stage 1 "low lift" cam in it now, that I bought for my 5.3. But I'm on 10lbs of boost "turbo" and the truck just isn't making power I think it should. I'm on 93 tune
Don't Get a TSP Chopacabra or BTR Truck Norris, they are fine for a 4.8 and 5.3, but larger, nope
@@shadowopsairman1583 yeah. I want a little sound at idle. But like I say, I know I'm way down on power. And I think the cam is a big part of it.
What is the rest of the combination? Hard to make a recommendation based on 6.0, 10 psi, SS1 cam, 93 octane. What vehicle is it in? Drivetrain? What kind of power does it make now? 10 psi on even a stock 6.0L should make around 500RWHP. And another important question - what are your goals?
@@bluecollarhotrods9781 it's got Cali rods, forged pistons. I used a good adjustable timing chain that I actually set -2 degrees to try to get just a hair more top end out of it. But it's in a OBS Ford. Air to air intercooled. As far as horsepower, Idk what it's making. Our local track hasn't been open for me to make a hit, to use mph vs weight to calculate true power. I'm assuming it is making close to that 500#, but feel like it's still not making what it could on 10lbs
@@darenwinckler7027 What gear? Converter? Transmission? Tire size? Vehicle weight?
What about nitromethane ? 😂
planned
