If the dyno is right, that's more like a 65-70% power gain in RWHP.

me thinks you are going to pop your motor. the TPC guys recommend removing any and all intake / exhaust mods prior to installing their kits. also, i seem to remember stock boost on a TPC setup being around 4.5psi. if you're running 7.5psi, you have a different pulley on your supercharger. be particularly careful running the car hard if it's cold. trent carter blew his supercharged 2.5 almost immediately after swapping the pulley to increase boost.

i'd talk with the manufacturer of the unit before you do anything at all.

I agree...7.5 is ALOT....all of the kits sold here are in the 4-4.5 lbs range and the turbo isin the 6ish but it had an intercooler. I am of the opinion a 7.5 lbs will blow the engine.

My iA supercharger is running 4.5lbs.

But..hey run with 7.5 if it doesn't blow your in a year I may do up mine
