  • Yea I agree No way the GT500 is putting down 404whp. What kind of gas r u using? Cuz that makes a big difference. My boys GT500 Bone stock. Maybe 2500 miles put down 446whp. Now I know all dyno's r different But down that seems way to low!

  • Richard said I had bad gas. I put 5 gal on 104 in and spanked a red GTO.

  • looks like it says 404?

  • yup 404RWHP. I drove an hour to the dyno and strapped it on.  Richard said I had bad gas and it was detonating a little

  • sounds great!

  • Yea 104 is a much better octane. But u really don't need that high of a Octane to get good #'s. Don't get me wrong it helps. But that could get very expansive. My boy had 91 octane when he dyno his. Now if ur not tuned for a higher octane. u could have detonating problems and start bogging out.

  • probably on regular unleaded. That thing should dyno from 425 and possibly up to 440 on a good day and more break in miles.

  • not all dynos are created equal, theres no way that thing only puts out 404 to the wheels.

  • what was the horse power i choulndt reallly tell???
