Wow you guys are funny. Being a V8 person it was hard to make the change, but iam glad I never gave up. I came on this site to ask a few questions because I had been hearing some whispers about the 4.0 liter & its potential .read for yourself how I was treated.there's a link below to my topic. So I didn't bother asking any more question. So I started asking around the traps for someone who new a little about turbo's. To cut a long story short engine is built we dynod it, made just over 1400 rwhp.that's in the car 2 speed glide 9 inch. So I was going through some car forums & thought I would post up on this forum what had happened in the last 6 months no big deal. I didn't think it would cause this much of a fuss being quite a large forum I would of thought some one on here would know the numbers that are being made. Obviously you guys don't know & 1400 rwhp is not that hard to achieve. like I said watch the drag racing scene, wait to you see there numbers. bye http://www.fordxr6turbo.com/forum/topic/76094-how-to-achieve-over-1000-rwhp/
