It’s mostly due to cubic inch, the more cubic inch the less boost it will make. If this blower were on a smaller inch LS it would probably make 10 psi.
There is something to that. I'm almost 600hp with a turbo Coyote on 5-6psi with the stock cams and heads. Even dropped compression to 9/1. I think a lot of it has to do with nearly 300cfm from those 4 valve heads.
I'm from a GM Family. My late dad plus he was a WW2 Navy vet, my late brother, and my late brother- n- law he was a Vietnam Veteran. My dad worked at Delco Battery, Muncie Indiana, my brother and brother- n- law worked at Fisher Guide, in Anderson Indiana. They would be proud of those awesome new Chevrolet power plants.
Pulley swap away from 900hp if you get 9psi out of that supercharger. It can easily go up if need be. High hp with the lower boost is nice though, probably last longer and be more street friendly.
It’s not impossible to do though. My families backyard mechanic has only one functional hand. With the occasional assistance, he does everything automotive. Mind over matter.
For real. As cool as it is to see the big numbers, knowing they're using a really high octane race fuel makes the point moot. Most people aren't using race fuel in their builds unless it's a full on track car.
@@michaelbannan9972 trying to build high hp with low octane fuel just isn't smart. That is a quick way to blow shit up trying to push things on low octane.
"After the AMC fans brought out their pitchforks and torches, Detroit Muscle wisely decided to use the 304." Damn straight! Far too many, "went with a LS engine," builds. Even if it's a LSX, putting a GM engine in an AMC heresy. From my vantage point, only AMC should go in an AMC. And I would be totally behind a punched-out and/or stroked 401. Because AMC was the "little car company that could," and to use anything but AMC is disrespecting the legacy. AMC fans are a loyal crowd and will always pull for the underdog.
They aren't the best engines out there but whatever lol. Coyotes and condor/trinity v8 4v fords and 03-04 cobra 4.6 4v motors all can make big power with just boost on a stock long block with way less cubic inches than the 7 liters shown here. Doing it with 4.6, 5.0, 5.4 or 5.8 liters max is dope. Dohc + boost is like a cheat code. This thing is a built highly modified 7 liter lsx.
Tire fryer would be an understatement. Would be more like tire vaporizer. If you manage to get even a fraction of that power down, that motor in an XJ would absolutely destroy everything from Chrysler. More power at literally half the weight.
🥺 O' now I want one in my TJ or XJ... but...😱 it cost more than both of them together 🥴... 🤔 That's going to be quite the sleeper XJ you all have got in the works over there 😁👍 😊 Can't wait to see it hit the track for the first time
Now it’s time to beef up the trucks frame, suspension and drive line to take all of that torque and horsepower. That engine makes enough to tear it apart.
one thing I don't remember you people ever really discussing is what type of oil do you use in these high horsepower builds. Do you use just a normal oil like a Pennzoil that's rated for high hp or do you use a synthetic oil such as amsoil?
Looks like the smaller pulley gave it belt slip or couldn't keep up...the first run didn't have that power dip from 6500-7000.... It may have been in the springs as well but looked like slip...
Need some larger diameter headers I believe, them glowing makes me think there to much back pressure. Not completely sure because of I’m basing from a turbo engine but to me it makes sense still with this being a boosted application
You should have gone full party pulley, I wanted to see the coyote you all built versus this with the same boost to see if the two liters or four valves was worth more power!
the biggest issue here is that no one makes "new" products for AMC engines. All the product lines have not been updated or re-engineered for the last 30 years. Powernation works off manufacturers giving them parts to hype. There is just no money in AMC. And this is coming from a real AMC fan. I've owned and raced Javelins, Rebels, Matadors, the works. I've built AMC engines that do go fast. But the reality is that engineering for ICE's has come so far from AMC that it is crude and limited. A lot of engineering advances have been "backported" to the Chevy 350 (the classic small block) and GM continues to build newer and better engines.
I think this proves two senerios. First, if you are building this for racing, go with a turbo charger. Second, the supercharged engine would be great in a street car, and there are different pulley combos to fine tune your engine.
As my ole Boss always said, "Ain't nothin that money can't fix" ! Why would anybody do this much for a 100 plus HP!? Funny thing is, I beat the crap out of supercharged vettes, in an LS1 powered RX7 that was stock! So, "THINK" about your bank role, and think about how to use it, because this ain't the best way! First worry HP to weight! Whatever you think, will kill your car before you even build it!
I mean at the end of the day cylinder pressures are about the same either way weather it's higher boost lower compression or visa versa. It might keep iat down and make recovery time better and be easier to cool the blower but I don't think it's really much better on the engine itself but at the same time some blowers don't like to be ran at such low boost and perform more optimally at a higher boost level. Each blower has an efficiency island that you should try to stay within for best results and not go under or over that.
Yes rock auto parts store is awesome AF and u can get ur parts really cheap but the shipping is where it will unalive ur wallet I bought a grill 4 an Oldsmobile paid 75ish 4 the grill but paid 61 bux just 4 shipping now know this I am NOT throwing any shade at rock auto cause they r awesome AF just need 2 figure out how to lower shipping costs
Can someone explain the 900 pens 🖊, cell phone, and glasses in his shirt pockets. Oh and don’t forget the tap measure to complete the Bob the Builder outfit 🥸
@@fairlanemuscle my rule is: LS swap anything and everything. If hotrodding is all about speed, an LS will get you there and its inexpensive and lightweight.
Amazing when you consider 376ci puts out 707hp and you lose 400hp on other boost. You hit the target tho and it only cost a small fortune. Good infomercial never the less.
It would make about 875hp. It adds 22.5 hp/pound, with 650 as it’s normally aspirated base line. 650+225=875. All this considering the blower could even move that much air in the first place.
They said the motor made 647hp all motor 19:05 min into this video. Then they bought a $7k supercharger not including accessories and only added about 140hp? Seems Waste of money. The dollars don't make cents.
It's a 427 that's built up from a previous episode, adding Octane booster to 93 and with the 2650 supercharger they should be hitting 950-1K Horsepower. They could hit 785HP with a built 6.2 IMO. Race Proven Motorsports does this all day on their channel.
I agree if that supercharger was any smaller it would be a restriction. That 427 is breathing some air naturally and needs something adequate to take advantage of what that engine has to offer. 4 to 6 lbs for the price of a magnuson, just not worth it, not much over NA. That SC would be more at home on a 6.0,6.2.

I'm just amazed that 6 rib belt isn't slipping hardcore. That factory tensioner is the true hero of this story.
I just had one of these added to my 6.2 LS. 200 HP addition.
I love how Pat thinks of the details in real-time by adding 2 psi of boost and using a smaller pulley to milk some extra ponies outta the LSX!
Nearly 800hp on just 6lbs of boost! Big power that's going to last.
It’s mostly due to cubic inch, the more cubic inch the less boost it will make. If this blower were on a smaller inch LS it would probably make 10 psi.
@@ReroyBrown not only that, but it has high flow heads and a big cam
This is a built 427 it should make that much power, Raceprovenmotorsports has a video with a 6.2 on 8lbs of boost making this much power.
How about not ruining the video in the first comment. Jackass
