KB 1.7 9-psi Kit Owners...Performance Stats Please

[saleen556]

I have the full kit. I have dynoed the car 3 times on 3 different dynos and got the following results:

KB tune. 401 hp 411 tq.
SCT tune: 416hp 428 tq.
SCT tune 2: 417 hp 434 tq.

Mods are in sig. I was running very lean on the kb tune (13.5:1 at 4k rpm when we let go) so I decided to get s custom dyno tune. Now I am planning on getting a smaller pulley... 10, 12 and 14 psi ones.... I will let you know what the AF etc is like and when the engine gave up.....I have a new engine being built as we speek so I just want to see how much abuse the stocker can take... I don't believe in the 9 psi being the limit.

Congrats on those numbers.Mine is getting tuned now and I hope I do as well.

There's nothing wrong with his car, you have the big tube option and a full exhaust. without it, you would have likely made about 15-20hp less.....which is about right on the money for a stock Auto equiped Stang with a base 9psi KB kit.

I still need a high flow catted x-pipe and headers. I hope to break 400 hp with does mods one day.

I got 376 hp and 404 tq at the wheels with a automatic . It was done with crappy california gas to .

Wow, that's good #s for an auto. A lot higher hp/tq #s than mine. How's the A/F? Just curious.

I thought there was a problem with yours that you were only seeing 6psi? Did you find out what it was, or were you mistaken?
