My 04 Cobra runs great.....of course, although just like most of the Cobra owners on this site they want more. So do I, so I started checking into some things and decided that I want to put on a 2.81 upper with a 4lb lower. Ill be using billetflow pulley's as well as their idler kit. I currently have only a magnaflow cat-back. I also want to put on Magnaflow's x-pipe and a K&N air filter system. Maybe a heat exchanger as well??? Well down to the point. I want it done right, not only safley but also carefully...I love my Cobra very much and have decided to take the risk of voiding my warrenty :??: Im not sure if thats the smartest thing since my car has only 6k miles on it but..........Thats what my little inner devil tells me to do :rockon: So I checked into and contacted some speed shops in my area and the best choice for me seems to be Blood Enterprises in Auburn Washington. I spoke with Chad there and he was extremely helpful. They were working on an 03 when I talked to him and he said that the car was running everything I was talking about and turning the dyno at 462rwhp. I would be throughly happy with that number. I only plan on spending about $2000-$2500 give or take. I figured they would put the pulley's on throw it on the dyno burn me a chip and on I happily go. Thats a perfect world. I really enjoyed their courtsey and I think I would feel comfortable letting them work on my car. I was just wondering if anyone here has dealed with them or if any one has any other advice for me? Thank You so very much for your time reading this thread and any help or advice would be greatly appreicated. epper: Sincerely Preston Moffet
