550 Primaries enough for e85?
Shooting for 400whp on e85 with a gt35.
550 primaries 1680 secondaries. Will the 550s get me to the staging bar? |

30% more fuel.
So whats the Duty Cycle of the 550s with normal fuel at 2psi? Basically i need to figure out what my duty cycle is right here: https://cimg8.ibsrv.net/gimg/www.rx7...00acb9829e.png |

I know they are expensive, but ID1000s would be your best bet for safety and tuning. They are far more precise than the 550s are, since they are much newer. I get that the point of the thread is to stay with the 550s, so I went and found a nifty calculator that states that at that PW at that RPM, you are at 57-61% duty cycle. In the first calculator, I input 7.6 at 9000 rpm. Later on in the charts, I saw around 61% at 7000 rpm in the third calculator. Stealth 316 - Injector Duty Cycle Calculation If you then shoot to 30% more duty cycle, that would put your injectors uncomfortably maxed out at 87-91% DC. |

Looks like I'm buying new injectors. Thanks for the input.

Yeah decided to go meth injection instead. E85 doesn't fit my needs for this car. |
