I was just trying to get a baseline number on what my 2008 Corvette should lay down at the wheels. The mods of my 2008 ls3 corvette are a comp cam 228/236 114 Lsa with comp 821 springs with titanium retainers. It has the cnc ls3 ported head castings and a full texas speed exhaust with high flow cats and stock npp mufflers. It also has a vararam cold air intake. What numbers should I be able to get out of My car. It's 6 speed manual z51 package.

Over 475 at the wheels. I'd say closer to 500 if you had an O/R X pipe.

JakeC6Racing

I'd guess around 480. Headers are 1 3/4?

LsPowa

Nope 1 7/8 headers to a high flow catted 3 inch x pipe to a 2.5 inch axle back

ProEFI

closer to 500 if you have a good head work.

For less than 100 more ponies, what's the cost?

LsPowa

they are cnc ls3 castings i got the from jegs

irok

440 to 450rwhp

smurfkiller

kinda of a more mild cam but still should be right near 500 rwhp

dyno numbers truly dont matter, every dyno reads different

but track numbers dont lie, take it to a strip your 60 ft time & mph will tell you right where the car is power wise.

LsPowa

I was going to go offroad but the gas fumes i cant really handle and ive seen a car with a little bit bigger cam and all of my same mods without ported heads and he laid down 497 at the wheel

TerryL

Embarrassing huh?

LsPowa

I agree with that 100%. I would just like to possibly get a ballpark range of where my numbers should be.

ruxvette

If you're thinking less than 100 hp as in from 430 to 500 then yes, it is embarassing...to you. You're talking apples and kumquats, here.

TerryL

Nope, all I'm talking about is dollars per horsepower and no one seems to want to say how much, including you.

walleyejack

whats the cost matter to you ? just nosey ? the op is happy, and that is all that matters.

ruxvette

I'll bite...at a guesstimate initial price of $65,000 for the first 430hp and a guesstimate of $6500 for the next 100hp it looks like about half the cost...$150/hp vs $65/hp...
However...430hp is NOT at the rear wheels.

Before my mods - 370 RWHP on the dyno ........ with what you have should be 460 - 480 ish..........
