400 hp stock but that's at the engine maybe 350-360 to the wheels headers intake and a tune will get you there

Living in CA, I would not of gutted the cats because of emissions inspection. They no longer preform the sniffer test here, but the smell will be a give away. Gutting the cats will net you a few HP and not worth the risk of major fines and failing emissions testing. Let alone a smelly exhaust.

To get to Z06 level I would add: Z06 exhaust and mild cam with smooth idle, so not to be detected by emissions testing. Car will need to be re-tuned. That will get you close. The other option, which is more expensive, a CARB certified supercharger, i.e. A&A kit. However, at 17 yrs. old I do not recommend this route even if you had the money.

As far as RWHP, I agree with "napp e roots" 350 - 360 RWHP.

400 rwhp with a cheap budget will be hard to get. Run name brand headers, vararam and a tune. That will get you close. Remember a vararam will not show any horsepower on the dyno. The vararam is one of the best intakes. The fastest C5 and C6's non FI run vararam.

Yes, auto's will have a little less HP. Other reasons, different dynos, ambient temperatures, C6 with LS2 or LS3, etc.

17% parasetic loss is pretty normal. A ls2 corvette likely puts somewhere closer to 330~340 to the tire. (source: https://www.corvetteforum.com/forums...q-for-ls2.html) In order to get 70HP at the tires on the dyno you are going to need headers, cam, and a tune.


Also, every dyno is different, calibration, weather, SAE vs STD corrected numbers, etc. will all play a factor in what a dyno reads.

Finally, why is your thread name CammedC6 if all you have is gutted cats & no mufflers (does that even sound good? Loud isn't good, loud is just loud)

Cam will come later in time and I love it and sounds great you get the old geysers who get mad and say it's to loud then you get the rest 90% jumping up excited telling me this thing sounds bad *** and sounds like a race car and looks

If your looking to run with a stock Z06....you will need to be around 475-480 whp as the ls7 puts down some nasty torque. The car Z is about 300lbs lighter as well...lighter is faster in most equally powered comparisons. Not sure of your budget,but If you could swing LT headers and tune....that would be your best bet.GL

Unless you are running from a standing start, you have to remember the wider rear tire will also play a factor.

400 rhp will cost more budget, I agree with above thread, there's some very informative conversation and research about this
