Decided to do a little dyno testing today. I had planned on doing 91 octane + alky testing, but wimped out at the last moment and added a couple gallons of 104. So closer to 94 octane + alky. Using a 75% mix of denatured alcohol from home depot and 25% water. Ran in to the usual problems at this power level. Spark blowing out, boost leaks from somewhere (wastegate opening?), etc. But all in all was happy with the results.
Boost around 18psi! Probably a few more HP in there with better nozzle placement, etc... Tuning continues...
