Well the temps outside just haven't been that warm so no turbo compound verses single turbo ABA results yet.
I built my new nitrous setup this Saturday and its a three stage system.
1st stage is a 75 shot dry direct port to ramp up boost at a stop to launch the car at the drags.
2nd stage is a upper rpm 30 shot dry that feeds into the turbo compressor.
3rd is for FE. Its a extremely small amount of nitrous that will be used to test in combination with lean burn. I did some testing on this a couple years ago. I found out that a small amount nitrous accelerates the flame speed so I can run less ignition timing while in lean burn. This should help to lower BSFC and increase FE.
I know this will not be cost effective because the cost of the nitrous, so its more for experimentation purposes.
