I figure you might be able to get in the 1.7x range with the 20" drag radials, but not much better.

No, it's going to take more power than that to get into the 10's. These are not light cars and the things that might have worked for folks with 4th Gen cars will not necessarily hold true with the Gen5. You should not be trying to compare what 530rwhp would accomplish in a 4th Gen to what the same power is capable of in the new car.
it takes more than 530rwhp to get into the 10's?? are you joking? 450 rwhp would get 10's on a 4th gen (M6). I bet 530 rwhp and 18" DR's will easily get in the 10's in good weather

i apologize, i missed the 20" DR's. I thought they looked smaller in the video.

obviously its all relative... a 5th gen on 20's isn't going to lay down impressive ET vs rwhp. its just comical to see people j i z z over something that is nothing more than expected.

anyone that spends 1500 on a cat-back or headers is a freaking moron. You can get a set of mufflers for $100 and have them welded in/installed and get the same or better sound/hp for 1/10th the price. you could also probalby go to home depot and make a CAI for $50. the aftermarket companies are going to rape people until there is a decent supply of aftermarket parts for the 5th gen.

How bout you spend a bit more time explaining the situation instead of LOLing at enthusiastic members.

How's that sound?

Maybe on a mustang dyno those %'s will hold up, but not on a Dynojet. For reference, look at all the SAE Certified engines and see what they dyno at the wheels. You will see that the typical set up loses ~12% for a manual, ~15% for the auto on a dynojet.

To be losing 20+% at the wheels, you must be running a 9" rear end + an inefficient transmission, such as a C6 or maybe even a TH400.

I guess you missed the part about trying to compare a Gen4 Camaro to a Gen5 Camaro. If I had the rwhp my GT500 makes in a '03-'04 Cobra, I could runs faster times, too. How about you get yourself a Gen5 Camaro, and see what you can do with it, stock weight and suspension, and get back with us. It's obvious from your posts that the rest of us lack your John Force-level skill set when it comes to getting the maximum times out of this car, so we'll just let you set the standard.

You are spot on Evil .... about 12% for manual and 15% for auto on the dynojet ..

Right the point is there is no way that 5th gen has only 12% loss .. Not even close . For instance Engine dynoed 402 ls motor made 607 at the crank on a superflow engine dyno . Installed in Corvette C5 [ I'm sure all who know whould agree 18% dr loss for 6spd car ] It made 514 whp on our mustang dyno .. that
We have done a large amount of testing as well as baseline runs on SAE Certed motors . Also back to my first post The 6l80e takes more power to turn like a 4l80e so less then a 4l60e

John at Hennessey,
I have a question about the HP gains. You show that you had a 14 hp gain with the CAI. What was the gain with the Corsa exhaust and did you try any others or is that the only brand you use?

superflow dyno's read quite high from what I've seen.

as an example, here is a superflow dyno of an 03 Cobra motor with a pulley only (basically, my set up)

thats 583 HP and 574 TQ. And that equals out ~450-460 rwhp. BS. That would mean a GT500, that makes 500 SAE certified hp and makes ~440 rwhp, really makes 550+ HP? I don't think so, otherwise there wouldn't be an SAE Certification program. Same goes with the LS3, LS9, LSeverything. EVERY engine that has been certified.

I will agree with you that an engine loses 20-20+% when going from a superflow dyno to chassis dyno, but a superflow dyno is not what is used to rate HP in the SAE Certification program and also is not the dyno used to calculate factory engine HP's.

At this time, we have not had a chance to test Corsa or any other exhaust systems on a Camaro without the blower. Hopefully we will soon.

Using your gt500 example [ solid axle less loss ] 500hp crank = I have stock graphs from 410-430 but I have 2 at 422 whp.. so 422 X 1.18 = 497 Why is this wrong ?

As for the superflow engine dyno they do have an SAE setting and we request it is used and our results seem to be within 1-2% ..

Also keep in mind a 3000lb roller can't create an equal a load esp on a 4000lb car .

dude, how are you going to compare a 4th gen to a 5th gen when the previous generation is like 450-500 lbs lighter.

Those are a little on the low side, but either way, your math is wrong. To correctly find the HP would be to DIVIDE 422 by .8x to find the loss. EXA) 422 / .85 (15% loss) would be ~497 hp.
