[QUOTE="98 Saleen Cobra, post: 16843434, member: 52734"] Well nothing good to report here.. Did head gaskets in the car and got to Modnationals.. still chasing a misfire and it torched the new set of head gaskets in less than 3 passes.. Head and block has damage now.. The YSI-B blower made 29psi in .6 seconds off the brake though.. so i'll have a runner here soon. Pretty bummed though. Good news is the 10rib belt is holding perfectly Lots of lessons learned here I need to pass to anyone who carrs. 1. The YSI-B blower at this power level is nuts.. It has bent 2 different crank keys. Even with the crank bolt tqed to 125ftlbs. So at this power level you 100% have to have a double key'd crank 2. Highly recommend you stud the crank like the 03/04 cobra's do. The Fix and upcoming mods to be planned: Double Key the Crank Stud the Crank Repair block and heads O ring heads and block Copper head gaskets (Prepare the motor to hold 40-50psi) Refreshed the engine, bearings, rings etc Kooks 1-7/8" headers with 3.5" collector and custom 3.5" exhaust Holley EGT bungs in every primary Coolant pressure sensor crank case pressure sensor I was going to sell the blower setup but my builder and tuner wants to see this through. This thing is gonna fly when it's all figured out. Kooks 1-3/4" with 3" collectors and EGR provision will be forsale soon if anyone is interested. Motor is already out of the car etc. I have lots of pics on my phone I'll try post up.. [/QUOTE]
