Default 408 dyno predictions

Ok Im going back to the dyno on sat. To see what she will do on the bottle and on motor.

Here is the thread that I started last time it was dynoed:

https://ls1tech.com/forums/showthrea...067&highlight=

The only changes for the n/a tune were cut-outs installed, a little more efficient converter, Race gas, 30* of timing, 13:1 a/f.

After the motor tune is dialed all the way in I have the direct port pilled for 300 at the tire. So we shall see what she will do.

What do you guys think?

Well with 431/369 before on the Mustang dyno...I am guessing that you are gonna be up to 465/440 and 773/792 with the 300 shot. Just be sure you turn down your timing and for your shot (I am sure you know this, but would hate to see you forget). I bet your tranny is eating at least a 100hp if not more. Good luck
