Its not a 3.8 pulley it's a 3.6 and they said 8lbs. Did u get a dyno with your 90hp and 50lbft.. I got one with mine

 

I gained 350hp and 550tq on 16psi

Lol, it needs a retune, man. There's probably another 100hp/tq left in it. The 6.2s are no joke, and monsters on boost.

 

Ya but it doesn't mean anything now, Ive made a bunch of changes. I won't have a time slip till may now because the track is closed for the winter.

 

Here are some pics snapped off just now.

 

Looks clean

 

Tall tires, mustang dyno....numbers should be expected to be low. Look at the gains. 90rw/58tq. Not bad for 8psi w/ a conservative tune. I wouldn't be discouraged, but I would be looking for a retune; for both WOT and drive-ability. If fuel trims are off, you could greatly increase MPG, especially once you get away from the SD tune.

Best of luck to you!! Looks great by the way!

 

Damn, that's a LOOONG air intake path....

 

Thanks for pics.

 

Thats a busy engine bay.


Dont get frustrated bud, more boost, cam, headers, custom tune you will have a 500 + rwhp monster!!!!!

 

i have a 2.3l whipple kit with a 3.625 pulley. I am making 6lbs of boost and hit 425rwhp and 440ftlbs on a dynojet so your numbers seem low for 8lbs.
