CANADA GUY Posted July 23, 2009 Report Share Posted July 23, 2009 Just wondering since a few cars are out there( with more coming daily ); if you have dyno'd yours and the results. The only 2 results I HAVE SEEN SO FAR ARE : EDMUNDS TEST- 511 EVO - 448 ( BOTH RWHP OF COURSE). MR. ARNING told me the 540 adverised( at the flywheel ) is the minmum - suggesting they are under- rated. Please chime in if you have info . Thanks !

I saw the edmunds test as well and I think either the car was non-stock or like you mentioned, underated by the factory. If underated, that is one powerful stock mustang. Hell, I got a cold air kit, 2.6 pulley and a tune and am only making 509 rwhp on a hot engine...low for a GT 500 with those mods...that's why I want to know the real deal on the rwhp of the 2010 GT 500. I think evolution's numbers are probably on target. Link to comment Share on other sites More sharing options...
OneTrickPony Posted July 23, 2009 Report Share Posted July 23, 2009 I can beleive that, Ford/Shelby did it in 1970 with the GT500. They were rated somewhere around 395 and produced something like 425. Tried to find the exact numbers in one of my Mustang/Shelby books, had to guess from memory. It will be interesting to see what kind of numbers guys post. Link to comment Share on other sites More sharing options...
GAFSoldier Posted July 23, 2009 Report Share Posted July 23, 2009 Forget the edmunds test and look at the numbers from evolution's there are the right ones. Link to comment Share on other sites More sharing options...
svt boost Posted July 23, 2009 Report Share Posted July 23, 2009 Forget the edmunds test and look at the numbers from evolution's there are the right ones. evolution uses a mustang dyno I believe, which rates low...the "standard" is dynojet Link to comment Share on other sites More sharing options...

goldgus Posted July 24, 2009 Report Share Posted July 24, 2009 Does anyone know what "best practice" is as far as waiting to dyno a car. Like, should I have XXXX number of miles on it before I dyno it? And will I void any part of MFG Warranty if something goes wrong while on a dyno? Sorry if these sound like stupid questions...
