I am trying to diagnose my car. Its a fresh build, and was running strong at 24psi boost, good clean logs.
My dumb ass forgot to torque down the caps that hold the drive shaft to the pinion, so when I was about to launch the car the bolts had eventually walked out enough wear the u-joints tore...
I just put one on my new "max effort" 109 build.
1. It looks bad ass.
2. It mates up to the 3" intercooler pipe
3. I had a bone stock throttle body and im building a mid 9 second car, so it made since.
No regrets, nice piece. I called him up and I had it two days later.
what did you notice about the 104 vs the 103s? How did it like it better?
My stock longblock @ 35psi on e85 ran best with stock heat range plugs too. no knock. I tried colder plugs and it ran noticeably rougher and I fouled a couple of them in short time.
thanks. Still wondering about the spacer. I have to go to my shop this weekend and look at it again, but I was sold a valve cover spacer, saying I needed it to clear the rockers. So wondering if I need two sets of gaskets or RTV one side of the spacer, etc.
