Dynapack testing - Mustang
Discussion
A very interesting morning with the 'Stang today; went to a sound session recording the Mustang for an up and coming game designed by my employers, EA (www.pistonheads.com/news/default.asp?storyId=13813). Dynapack was attached to car with rear wheels off, and a variety of rev ranges recorded.
What surprised me were the results - using the US SAE readings, we took app 265bhp at the wheel, which I was told should have app 40 bhp added to it to give an "engine" bhp. This represents app 300 bhp, or 40 above US stock SAE readings. Has anyone else experienced this (car is 6 yrs old, 85k mile on clock)?
Generally an interesting experience all around, although I did get a little concerned at times when the revs were at 5k rpm and we were in a small enclosed room!

Any modifications to the car? I am considering one of those plug in programmers myself, here that they help drive ability.
None whatsoever apart from a pair of flowmaster mufflers which may liberate a few horses. Think it actually helps that it has 85k miles under its belt and has always been serviced timely and appropriately. A pleasant surprise it has to be said.
Japan an amazing country - am sure you are enjoying it.

It's hard to believe anything the Americans claim about power outputs.
As a few examples, the Americans claimed 345bhp for the 1998 C5 Corvette and 305bhp for the 1998 Trans Am and the TA put out more rwhp than the Vette (TA was 292bhp).
Muscle Mustags and Fast Fords tested a Mustang Cobra which claimed 390bhp and got something pretty near to that at the rear wheels. A 325bhp Camaro SS put out 317bhp to the rear wheels.
They reckon the 405bhp C5 Z06 would have to put out 425bhp to achieve the quarter mile times it gets.
Some claim the 300bhp of the 2005 GT Mustang is conservative. My view is that the Americans are so anal about power claims that you can safly assume that the power output means "not less than", in other words they guarantee their power outputs because everyone has a rolling road near them and some suggest for insurance reasons.
Dynos aren't that accurate however as it's always a calculation from what I understand. They are good for comparative readings between cars in the same conditions though.
