You do understand the difference between crank and wheel hp numbers right?

The reason no one has posted a dyno with over 400 hp, is because dynos report wheel hp numbers, which are about 20% less than crank numbers - due to drivetrain loss. (Depending on who you ask, they may say 19% or 18%) To get a dyno of 400, you'd have to have 500 crank hp. No one is there yet, and I don't know if anyone will with this car.

Alternatively, it's not hard to push 350 crank hp up to 400. As far as a dyno is concerned that would be pushing 280 up to 320. Here's a dyno of one:

The blue line is stock, the red is with SC pulley, the green is with intake and pulley. Note the 322 peak hp. Convert that to crank hp and that's 402.5.

Or here's another one from the Code3 product page: 324 whp.

If you take Code3's data and go to this website (which I found the conversions to be really accurate - having run on three different dynos and compared) and enter 324 in the hp column and 6,000 in the RPM column then press "calc" and scroll down to if your figures are on a dynojet dyno: you will see it converts to 381 Crank HP. (about +18% above whp)

I know for a fact that Code3 posts dyno charts that are converted to DynoJet numbers from pulls on a Superflow Chassis Dyno - (which is a very accurate conversion I might add) - obviously bigger numbers always look better when your trying to sell performance mods.

I laid down 362 whp on the very same dyno using the very same conversion Code3 used, which converts to 426 crank hp.

 

Very Nice!
