Got the car running good, new turbo TA-62.(009) injectors,walbro 340,heads P&P 1.77in 1.50ex, RJC power plate, adjustable fuel pressure regulator,3200 9/11 converter, trans just rebuilt and all new sensors. Have a Testa chip 18* Timing 93 Octane. How much more power would I get from running a 100 Octane chip with maybe 24* of timing?
boost and timing plus the appropriate fuel will always make more timing than either alone.
A 100 octane chip won't buy you much with 24 degs of timing, but, a 110 octane chip will.
Power increase with boost does not seem to be linear. With that turbo you need to run around 24-26# of boost to get into the part of the compressor map where that turbo really works. That will probably give you a second over what you can run on 93/18 or a half second over 93.18 plus alky IF you run timing and fuel to match.
