Can we talk about the 1,000 hp elephant in the room?

1' is how far your foot/pound wrench is from the center of the shaft. So spin it all around, about 2'. So 2x3.14159 is about 6.28. Guessing that's what he's saying without looking at the problem or the math. Just made me laugh.

Honestly not sure. I was curious about the 5252 as well, so when I Googled it that info and article came up. So since it was on the innerwebs it had to be right...right?

Apparently not.

My cammed and tuned lq4 made 458hp at the crank. I might make 500 with heads and bigger injectors. I was pretty pleased with it. One day I might make a stroker out of it to get around 575-600 at crank

How do you make 128-158HP with a cam alone? I assume it isn't a radical cam that needs a 3500 - 4k stall.

Btr stage 2 and my injectors are maxed out. I will see if my tuner has the sheet on it still. Have a 2800 stall. I'm no engine builder or expert on them by any means. I had never installed a cam till I built this buggy. I just know what it showed on the computer screen

Data given to me by a very reputable ultra4 tuner is that ~460hp is the limit for reliable and driveable HP on these (Gen III) 6.0s before you start needing injectors and head work. But that its pretty easy to get there with a cam and tune, and you can actually get a surprising amount of power out of a completely stock motor on tune alone, but you run into hard part limits that you just cant get around no matter how you slice it around a certain HP line...but beyond there the HP/$ line starts getting a lot flatter. The guys with the 600hp 6.0 by cam and tune are full of the steamiest, liquidiest, smelliest **** possible

Here is what is possible with deeeeeeeep pockets.
Koenigsegg Agrea RS is an over the top engineered automobile. Here are the engine specs alone as to what is possible.
Koenigsegg twin turbo aluminum 5,0L V8,
4 valves per cylinder, double overhead
camshafts, dry sump lubrication
Compression: 9.3:1
Bore: 3.62" Stroke: 3.75"
Total engine weight: 189 kg (416 lb)
Power output – gasoline – 865 kW (1160Hp)
at 7800 rpm – redline at 8250 rpm
Torque: 1000 Nm (737 ft-lbf) from 2700 to 6170 rpm
Max torque – 1280 Nm (944 ft-lbf) at 4100 rpm
3.8 HP per cubic inch !!
The car only weighs 3075 lbs
3075 lbs at 1160hp = a power to weight ratio of 2.65 hp per pound.
That is impressive!

There are mid 80s turbo BUICKS that have made 6 horsepower per cubic inch with 1 turbo, just saying....

But forced induction really is whole different animal

That is true. My LQ4 had hydro locked and bent a rod. I didn't trust the crank afterwards. I used the bare block and built the engine with new LS3 heads. Mine is supposed to be 565 and dynoed at 315 at the rear wheels. I can't imagine what 1000hp would feel like. I am having to learn to drive all over again with the increase that I have.

lq4, TSP heads, custom cam, maxed injectors and dyno'd 300 on my 43s/h1s. feels fairly strong to me and has enough whapow to get in trouble quickly. like mentioned, hard to imagine another 100 or more on top of that.

Im into the corvette world quite a bit. One of the biggest part suppliers is east coast superchargers. With a basically stock ls3 and supercharger with meth injection they are hitting 800rwhp with ease. Giving thats a corvette and not a buggy. RPM in garner, NC who built my vette had a stock ls2 with supercharger that they pushed to the max and it made 881rwhp i believe. Ill look for it and see if i can find it. Remember thats a unopened engine, no cam, i take, throttle body..etc

highrolrcustoms · Dec 18, 2018

Correction. It did have a cam but made 821rwhp. Thats crazy numbers for a LS2

That blows my mind if it is accurate. I have just never heard of gains like that. Insane dollar per HP.

I may throw a mid range cam and springs at my LS2 at some point. Not sure where it would be. I already have a intake and the stock 243 heads would love some more air. It is funny how it goes from so quiet and tame to serious now.

Most LS motors will make some crazy power with boost if the rings are filed so they don't close the gap an break the piston. Something like a LS2 or 3 that already flows well make it under lower boost for sure.

Texas Speed told me that a stroker kit would only add about 15 hp with my stage 1 cam and LS3 heads but a much flatter and usable torque curve.

HP is over rated. Torque makes such a big difference in our application.

I would for sure think the money for a LS stroker is worth it, if you can swing it.

Or go big block if you can fit one in your chassis.

Supercharged is the way to go in the offroad world, but anything boosted brings a lot of complications, added components and stress to the whole drivetrain.

I would LOVE to see some dyno sheets...

Mega truck and big (LEGITIMATE) hp mud truck guys laugh so hard at some of these bouncer guys. Like...they are the butt of non-stop jokes in that community based on their absolutely 100% false claims of hp numbers. This whole thing is as old as motorsports...everyone always puffing up the numbers a little bit. But its gotten to a comical point now where someone just looks at a shiny set of valve covers and reads the part description in the summit catalog and boom "that there is 5000hp"

I've never heard a mega truck guy make fun of any bouncers and I've stood at the bottom of many hills with a bunch of them on multiple occasions. Just saying.

I'm sure it varies between folks, but the ones that I've been around all had the same thoughts about it

Granted, there are just as many HP liars in probably every side of motorsports....but they all get made fun of in one way or another by people who just dont buy into the hype

People roll their eyes at me when I say my 22r makes triple digits.

True. I got made fun of because of my poor choice of engine for the last 4 years. Stupid diesels.

I know firsthand that an engine that makes big torque numbers but mediocre hp numbers will hurt alot of feelings. Build 400lb/ft at 3,000rpm and you'll have people swearing youre making 600hp.

This right here. Add 100 shot of spray to that and people start calling it an ls motor :****:

I was watching the buggies on cable hill video this weekend,, Watch the contact patch on the stickies go from 11" to 3-4 inches when the wheel speed gets high.. like a top fuel car these bias tires just get taller and narrower. That is why lower tire pressure light power rigs do so good on some stuff. tread contact .. on the 43's the center at high speed is almost a 4 inch slick , on wet rock. Hey if you can get that 4 inches dry and hot.. It works.
