WOW. I'm thinking crank HP might be a little more than 480hp. Not losing much at all to the rear wheels otherwise. We could be looking at 500hp at the crank. :like:

Are the A10's about the same loss from Crank to wheels as the Manuals these days?

We need it done on the same dyno with same air temps to see accurate comparison.

Steeda's was not done properly. They didn't run it up to redline.. Think it was 1000rpm short

You didn't get peak but you still got the plot of the numbers, there wasn't going to be a random MASSIVE jump at the end.

That could be right. 18+ are right around 430/396 on the a10 and 6 speed.

Steeda's dyno stopped at ~6300 rpm and they only got 403whp
That's not right
Should be more than 18+

They were short, give the 350 intake I don’t know how much the would have picked up but had they taken it another 1000 rpm it isn’t unrealistic given that intake they could have picked up another 40rwhp.

Look at a Bullitt dyno, identical engine. Even with an 93oct ECU tune from Lund or James you're barely getting another 20-25WHP, and OEM tuning can't go that aggressive due to the standards they have to meet. So you're not going to suddenly have the same WHP as a tuned car with the same engine.

There are vids of shops trying to say the Bullitt made over 450whp too, but those are WAY the out lyer. (example saying 461whp: 2019 Bullitt Stock Dyno Run - YouTube )

MOST accurate dynos are in the ~430 range, give or take 5, with an occasional push out near 440.
