Flywheel HP * .55 /.8 /8 = recommended injector size.

If your 1200HP is flywheel, then you need an approx 103# injector.
Feel free to call if I can help you out on a set for your application.

You didn't take into account fuel type?

I take into account the info that I have.
That was for gasoline.

If it was for E85, they should have said so....

Lonnie buddy what do you think I need? I don't know how much power the car is making but it weighs 3600-3650lbs and run's 8.8-8.9's at 160 and some change.

My SMP 120's are showing 110%DC with meth. I don't think there working to well, Mightymouse here found his 120's to be overated and found his 96's actually flowed more.

When I was running 9.0@155 i was hitting 84%DC with the 95's.

I have an F1X coming to replace my YSi and i'm hoping to run mid's@165+.

I'm still waiting on that paypal to get another pump!

BTW-my car runs faster on the fat side-hi 10's AFR.
