-UPDATED APRIL 2011-

From what I understand, from everything I've read and seen mostly in the "Dynamometer results and comparisons" section of LS1TECH, 500RWHP is possible on a stock bottom end, hydraulic roller, manual LS1/LS6 Camaro or Corvette without nitrous, forced induction or race gas. Tell me what you guys think and maybe share some heads and cam experience as well. I know this setup is on the extreme side but it has been proven to make the power. I would even go as far to say that its guaranteed to make 500RWHP.

This can only be done with manual 6-speed Tremec T-56 car.
EDIT: I stand corrected, Chris1313 with his 4-speed is making 522RWHP(INSANE!)

Certain parts should remain stock to help with power including:

-Aluminum driveshaft
-10-bolt rear-end
-3.42 gears
-Rims
-Tires

Guaranteed recipe for 500RWHP, stock bottom end, hydraulic roller, M6 LS1/LS6:

-Chris1313 ram air mod
-K&N oiled cotton filter
-104mm FastToys airlid
-No MAF/4" straight hollow pipe (Speed Density tune)
-FAST 102mm throttle body
-Tony Mamo ported FAST 102mm intake manifold
-Tony Mamo ported AFR 230cc V2 heads with XXcc chambers for XX.X:1 compression
-Cosmetic gaskets 0.0XX" MLS gaskets for 12:1 compression
-PatG spec'ed cam OR TSP Tsunami camshaft or some other all top end cam
-KOOKS offroad headers with 1 7/8" primaries and 3" out
-KOOKS offroad 3" true dual exhaust
-No AC
-No power steering
-Mezeire electric water pump
-ATI harmonic balancer with 25% underdrive
-Star Machine belt driven crankcase vacuum pump
-7000RPM OR + redline
-93/94 octane gasoline
-Razor shap professional tune done on a dyno

and voilą...500RWHP and maybe, just maybe, a little more

lol

*Also, the torque should be at around 425 to the wheels

remove the a/c and power steering? no thanks lol.. You could get 500hp with a cam heads and nitrous and keep that ****. I think at that point I would just do work to the bottom end. Plus, the stock 10 bolt isn't going to hold that much power for more than 1 pass lmfao..

Have you read Pat Gs recipe for 500rwhp?

garygnu

I would get a custom cam.a vacuum pump would help also.

Who hasn't, the guy has some cool tricks up his sleeve. His 2000 M6 Trans-Am has 508RWHP and 445RWTQ on stock cubes! I believe he has forged pistons in his setup but that kind of power on stock cubes is simply amazing.

eray

I am getting ready for my 500+ na streetable build as well. I'll start with a 383 though. It can be done just not cheap.

Anybody else have any ideas?

Yep, .040 gasket, TFS 215 heads, larger cam than the tsunami, lower intake lift, and 2" primaries are for max effort 427s, keep it 1 7/8"

I think you really need to ditch 3/4 of your idea's and if you are serious talk to a sponsor about doing it. It definately isnt easy..... And you dont need 2" Headers on a 346 ci motor, I have 1 7/8" on mine, and Im at 500rwhp on a 346, My rev limiter is set to 7800 rpm, and I shift at 7700, so they flow plenty.

I dont think PRC will be in your mod list, no offense, and to do it reliably with hydraulic roller you are going to be precise with your lifter preload, and running GREAT valvesprings. Cam is going to be custom too...

Just a little food for thought....

Turn some truck manifolds backwards, single 70mm turbo, monster injectors
on E85........done

Sweet another 500rwhp thread!

i am running 500+ with a fast 90 ported and port matched to a 93 to amtch my new tb with a 224 114 cam .
the intake manifold usually restricts the best of heads that flow 290 or 300 since a stock fast is 270or 280 cfm . ls6 intakes flow like 260 if memeory serves . non ported of course .

all my port work from heads to intake etc.. are self done .
course have some experience doing this but i am certainly not the best i just learned from the best on this board .

proper size pushrods , gaskets , a lot of variables come in to play . free up as much power as you can cheat from the engine then research and put in the right kind of parts down to claying the pistons to make the most out of what cam to use .

for power a 114 cam makes more power and runs a higher mph when a 112 makes more down low and is good for the track . of course this is cam to cam . even valve lift of the cam comes to play when shaving , decking , gaskets then pushrods .

kind of like cooking , everything has to go together and a lot of reading and trying other things goes a long way .
just my .02

I'm gonna get in on this
I got a 98 ss camaro ls1 s/c head work cam etc just had it on the dyno and it made 460 rwhp but I have a stock rear end how long you guys think that's gonna last at 4000 rpm on a m/t slick

+1 on Pat G's 500whp. recipe. He has thoroughly covered this topic. However, your combo sounds like a definite winner!

Yes sir! Its definitely possible and people on this thread like Pat G and Tony Mamo have achieved.

I updated the list to include the new AFR 230cc V2 heads which are basically upgraded 225s.

I also mentioned that they have to be fully hand ported to further maximize their gains.

When the LS1 came out in 1997 in the Corvette and 1998 in the Camaro, people dreamed of pushing 425-450RWHP and only a handful of knowledgeable people could pull it off similar to PAT G and Tony. These days, it is common place and everybody can do it. Automatics are doing it for crying out loud!

The dream is now 500RWHP.

Will it some day become common place? Will it stop there?

++ 1 On Pat G RECIPE !Also check out Chris1313 setup his car has gone 10.08Fast 102 setup .H/C with rod bolts.
You will need some good work on your heads & intake by Mamo or someone close to his level of talent ,Chris did his own work on his Fast 102 setup.

The ingredients to that recipe have improved since he wrote that article. 4 years have since gone by and important improvements have been made making it possible for us regular folks to obtain similar numbers.

After reading through the parts list of his "recipe" I have taken note of the parts that improved like...

-90MM MTI airlid VS 104MM FAST TOYS airlid

-102mm speed density VS 100MM TexasSpeed MAF

-FAST 90MM VS FAST 102MM

-FAST 90MM throttle body VS FAST 102MM throttle body

-AFR 205cc VS AFR 230 V.2

-Custom cam VS More potent off the shelf cams like the TSP TSUNAMI for example

-KOOKS 1 3/4" headers VS KOOKS 1 7/8" headers

-Y pipe with 4" merge VS KOOKS OFFROAD 3" true duals catback exhaust system

So many new advancements since 2007!

I believe our car(4th generation f-bodies) have received an larger than usual push from the aftermarket forming an incredible list of aftermarket parts simply because there was no real successor except the GTO from 2004-2006.

What can we expect for the future say 2015?
