Need recipe for 500 rwhp
I'm looking for a recipe to get a C5 to 500 rwhp with the following restrictions:
Emissions legal
No NOS
Stock bottom end
Anyone done this? Is this goal reasonable? I was thinking mild cam, p&p heads, FLP longtubes, Magnuson blower at 6-8#. Will that put me there? :skep:

Re: Need recipe for 500 rwhp (LT1LS1)
I'm looking for DIY mods, not a turnkey service. So if you could list the mods you people have done to reach the 500rwhp mark I would appreciate it! I just want to see if this goal is realistic for me or if I will disappoint myself. I made 524 rwhp on my LT1 but it failed emissions like the gas guzzling horse it was. Definitely need to make this LS1 project street legal, but I would really like the same power levels!!!

500 rwhp I would think that would be pushing it with a stock bottom end but that's just MHO.
The main ingriedant though is cash, mucho denero $$$$
mix together some good intake stuff like a good air induction system, Z06 intake, and maybe a 80mm TB.
complement that with a set of LT headers, X pipe, cat back exhaust, and maybe some hi-flow cats.
Now the serious stuff...a good stage II heads & cam package.
while your in there put an under-drive pull on.
Add the supercharger and your ready to get your PCM re-programmed.
You will need a new clutch, flywheel, M/C and slave to handle the power also
That should net 500 rwhp pretty easy.

edit: nevermind. I had mentioned to look up No Mercy, but you're looking to go the blower route, so that won't help much. Sorry. :)

Re: Need recipe for 500 rwhp (DsC5)
It is doable for about 6-7k doing the work yourself. See my sig. That is about what I have spent. The reliability is questionable though, I’m still working on the tune and a few other issues. The roots style blowers will most likely not get you there, you probably need to go centrifugal. I started out with a goal of 500hp for 5k, but I've pretty much given up on keeping it cheap now. You’re just going to end up breaking things and needing more stuff than you ever imagined when you get that much HP. I've pretty much accepted the fact that I'll probably end up doing forged internals before it is all said and done. I never thought I would actually be thinking about getting a spare motor for this car. It's almost like a sickness, be careful, you will probably end up spending way more than you originally planned.

Re: Need recipe for 500 rwhp (tshac)
Like I said... don't want NOS. And a 200hp shot is a little much for stock pistons!! :eek:
ChrisNJC5 - you really think I could reach my goal without p&p heads? If so that would be great! $1500+ for smoothing out some metal has never sat right with me before... :U

It seems to me that if you want 500 at the wheels, you should plan on CNC heads at minimum...then a s/c. I think with the right planning you could get 500 with the magnuson setup on CNC heads and it would have great driveability. HOWEVER, remember that 500 is defined as the limit of what's reliable on a stock bottom, so you'll likely end up messing it up. IE< PLAN ON SPENDING MORE MONEY DOWN THE ROAD.

Re: Need recipe for 500 rwhp (PaceThis)
oh yeah, and while you're doing the heads, I should have mentioned, you should switch to the LS6 Heads with 02 Valves, Dual Springs, Tit. Retainers, a full set of LT Headers, X pipe, no cats, catback exhaust, new air intake, LS6 Intake Manifold, S/C cam, and a blower (magnuson or ati; note magnuson will not need LS6 intake manifold).
Note, LS6's with Headers, Air intake, and magnuson are hitting 460 reliably. Add a set of ported heads, a slightly more aggressive cam, etc and you should be pretty good...

Re: Need recipe for 500 rwhp (PaceThis)
Sounds sweet guys! Thanks for the input. I think I'll do the items PaceThis mentioned except for the LS6 heads (poor $/hp ratio IMHO), and no cats (emission ****'s). Hopefully I can go 2-3 years with that setup without blowing the stock bottom end. I squeaked by on my S/C LT1 for a year before it went boom, maybe I will have better luck this time around. :hurray:

Could be done. . .but without the CNC heads, you'll end up with more boost, which seems like it'd wear the engine out quicker...maybe not...

Re: Need recipe for 500 rwhp (jcobz28)
Have you considered procharger at all?
There are guys running 322 rwhp on stock V6 mustang bottom ends, 11# Procharger kit with a '99+ V6 Mustang engine (stock HP ~190 at the flywheel). Here is what that particular car had.
11# ProCharger kit (we saw 13# at 6000)
42#s injectors
Pro-M 75mm
255 pump
JBA shorties
MAC high flow cats
Flowmasters
5 spd
I think the procharger site claims about 540 hp (crank I assume) for the LS1 setup. Do some more work with exhaust, cam, etc. and I bet you see over 500 rwhp for around 6K.
Good Luck!

Although this isn't 500 rwhp, it's a heck of a start and the TQ is large. http://forums.corvetteforum.com/zerothread?id=452488
