Injectors for 800+ whp

[Drazga]

My car made around 700whp on a very rich 93 octane tune with about 17.5* of timing and 20-21psi no nitrous. Full exhaust, stock heads, stock cams, stock motor. 2.8LC Mammoth Kenne Bell. I currently have 80lb injectors. I'm going E85 now and shooting for 26psi 20*+ and around 800whp (stock motor for now) with a small shot maybe a 50 or 75 shot.

Would 105lb injectors be enough?
What about ID1000s? What is needed to run IDs? Are they that much better?
I'm assuming I need a 30% larger fuel jet for the nitrous as well?


I can't wait to post up the numbers after I get it tuned :beer:

What type of fuel system do you have? It can be done with FRPP 80s, ID1000 (95lbs), or 105lbs. Just depends how good your tuner truly is. Not sure how long your engine will last though.

If the motor goes, it goes. I'm surprised it lasted this long with how hard I drive the car. I have a return setup 2x 340s, 10 feed 10 return, aeromotive regulator, rails, 80s, etc

Dude on 26psi and a small shot your gonna be way over 800! 105's atleast, good tuner or not it's safer.

We went from Siemens 83 lbs injectors to ID2000s. The Aeromotive A1000 pump ran out of fuel at 969 ish. 1111 foot pounds of torque is interesting. We are at 23 psi with a 4.0 liter Whipple. I think it was the nitrous that maxed everything out.

Thanks. ID1ks are similar to 105lbs right? How do you like the ID2000s compared to a bigger injector (60lb, 80, 105 etc)?

The ID2000 injectors are rated at around 221 lbs per hr. They were incredibly easy to scale and phenomenally easy to tune. I had a lot of concern going to that level but the ID2000s may be by far my best Mod. I could not go to E85 with my 83 lbs Siemens injectors
