Ported & upper pulley only dyno numbers.

[Logan2003Cobra]

I recently bought a stage IV with a 2.8 pulley on it and I don't plan on running a lower (don't want the extra torque). I'm curious what people are putting down with their ported blowers and upper pulleys. Thanks,

Logan

i put down 486hp/480tq with a conservative tune, 2.76 upper only, stage 4, catback, and FIPK, with the stock midpipe. with a more aggressive tune, i put down 505hp/490tq

Those are pretty good numbers... what was changed with the tune?

I put down 508rwhp and 498ft/lbs of torque! Mods are in my sig!

i was going lean at high rpms due to my injectors being maxxed out--just over 12.0 a/f ratio. got bigger injectors, and 11.6 a/f ratio gave the final #'s. with the stock midpipe in place, i was seeing just over 15lbs boost.

sonic how much psi were you seeing through the longtubes and o/r midpipe?? I didnt need injectors...just a BAP and MAFia
