(02/10/06) I got a printout from Coleman Racing Engines and I turned it into a page so that everyone can see the numbers that were produced on the dyno. The numbers look great to me and I can't wait to test this out from the seat of my pants viewpoint.

I was very happy with the setup of the dyno and hearing it run was just a great experience. A lot of time and effort went into making this engine. I planned poorly on a few things and that cost time and extra diesel to get up and back to the place. The shop is about 20 miles away from me, so 40 miles round trip is not something you want to keep doing in the days of the high gas prices!

The next page will detail out all the things I wish I had done in a different way or planned accordingly. I will also be putting up pages of the engine going back into the Jeep as well as the cost for the entire heart transplant. The prices aren't going to be pretty, but with the work done the correct way by guys who know what they are doing, hopefully this is the last time I will ever have to sink money into the engine of this Jeep. Hear me knocking on that wood?
