for a fact? then where is the dyno sheet? The seller might have fooled you but can't fool me. It is impossible to make that much torque on 14 psi unless your KA is a 3.4L or it was dynoed on 30+ psi. The hp # isn't impossible but without cams and plenum I have my doubts. I will make you a deal, bring it down to the shop to dyno if it makes what you claim I will pay for your dyno and Martin will give you a $100. If it doesn't then you have to pay for your dyno.
My buddy Paquel that owns Godzilla (RB30 S12) and Mad Kat (KA-T 510) both can give me a full second head start when we bracket race at Lakeland and still walk the Punisher. You can find the videos on Rabule Pistón Vs Rotor
