After driving the 2011 Mustang & being disappointed in the normal driveability (guess I expected more due to the hype) I searched for some dyno sheets. I don"t know how true (claim to be stock) any of these dyno #s are but here"s what I have for the 2010 & 2011 Mustangs GT.


2010 GT


2011 5.0 Manual


2011 5.0 Auto

Wow quite a large power difference between the auto/manual

RAMAIR

Well that is because the manual is a very high above avg dyno and the auto dyno is very low below avg.

I would say the norm is more like 375 rwhp is avg for manual and 360 rwhp is avg for the auto.

Alec

That's still a pretty good difference

RAMAIR

It's a difference but nothing like 340 rwhp vs 395 rwhp. Also the auto does not have a 1 to 1 gear ratio so that cause the auto to read hp a bit lower than a manual. Even with a 1 to 1 the auto would read lower maybe by 10 HP which isn't much imo. In stock form from what I seen the auto has put out the best track times which imo is what counts most.

6+6 Stang

All I know is I had a 2010 GT 5 spd for 14 months, and now I have had my 2011 V6 6 spd manual for 2 1/2 weeks and when they make a procharger for this baby it will probably stomp a stock, 5.0. I did not say for a fact I said probably, but the 6 can almost take the 4.6 now, supercharge the 6 and the stock 4.6 won't even come close. Maybe I can go from this stock look to this in time LOL.

3.8 front engine noise on start up like a bearing is failing with the belt off. After a while it kind of goes away any thoughts of what it could be

Looks like the results are from two different dyno's? Maybe that would account for such a large difference. An automatic transmission wouldn't eat up an extra 45 HP.

Your already supercharged?

6+6 Stang

no, that's why I said. "when they make a procharger ", I photoshoped that as my future dream mod lol
