It will be a few weeks before I can finish getting everything together and get it to the dyno. Just wanted to see what some people thought it would make at the wheels.

If built correctly you should have no trouble exceeding 400rwhp.

^^^^Agreed. But my five year old girl might be able to put that together and make a minumum of 400+rwhp

. Let us know when it's done.

Mark.

I am hoping for a little more than 400 at the wheels before I spray it. I would like to see around 430 plus.
