RE: Why do autos dyno low?
Well why didn't you tell us about that stuff before? lol. That will make a slight difference in it. It's nothing but a pure guess, but I'm probably bump my estimate to 275ish ( with the auto still eating up some HP.)
Hey, I got an auto too so I know the feeling

+1 along with the 95mm MAF as well. But who knows, maybe he's planning on boosting it...

30lb injectors = overkill IMO

RE: Why do autos dyno low?
I've been told that an automatic trans will use about 20% of the engines power while a stick will use about 17%.
This is a percentage thru the whole drive line.
The 'U' joints sure do use some but I've never seen anything but " a minimum of 2% each" and that was from a Mopar book, written by Mopar over 20 years ago. Bunch of poer gets used in rear axle also.
I've also seen in print, that a C-4 uses 25HP to operate........
The C-4 will use less power to operate than any other Ford automatic.
Also, even the finest convertor will slip about 2% on the top end anyway, thats why you see trans coolers on real race cars.

The "Top End Kit" is that H/C/I or just an intake?
