Any one know whats up with such the big drop?

Your torque is a relation to your hp. The SR isn't a torque monster but it makes more torque then other dohc motors. Also depending on the turbo and response and tune tq #'s will lay out differently
The actual # don't mean anything its the powerband and keeping the torque as flat as possible minimizing drop

470 on 93 is a VERY good number, especially out of a 5558 .63.

Haven’t seen any other precision threads and thought it may be ok to bump this old thread to see if any more guys out there want to provide input? Debating on a 5558 or 5858 setup at the moment myself

*anti tyler* · 10-01-2017, 10:24 PM

I had a 5431 once, bolted onto my insane KA.

Made 375HP on 7lbs of boost. I wish I would have gotten to swap all of my hardware to a straight chassis.
