That may be.(the flywheel claim) And I can run 11's with 390rwhp(agressive build). However. with the weight and needed supporting mods you may only cut 12's. If you do better then great. But it is a 3.0L. It should make amazing power.(especially for the cost of the unit) And I'm not shitting on anyone. I am just stating that they have not put down power.
And jim jr last time I heard made 530something with the built motor. But it may be different now. I will dig up the modded thread so you can see where I am comming from. And again I'M not trying to shit on anyone. I'm just saying What I have seen and heard.
