Now info: I have chosen to run E85 fuel. Easy to get here, and cheaper. While I have to now nickel plate or anodize the fuel rail (aluminum), I already bought High Imp. 72lb injectors because I didn't like the issues with low impedance.
Well, now that I will run ethanol, and will need up to 40% more fuel, I may need even more than the 72lb injectors at high boost and high rpm, since sequential, per A. Graham Bell's "Four Stroke Performance tuning" book must be run down to 65-70% duty cycle, or there is no real advantage in power. There are 160lb metahnol compatible injectors which would be better for the ethanol, but they are always low imp. Q: I suppose I can just order the unit with the low imp. option, but will that then limit me in the future? Q: Will I have enough control to run the 16olb injectors at idle? |
