Here is my situation, I hope JDM will finish my truck in 2 weeks.
Ford aluminum GT-40 aluminum engine,
Ported heads,
Moster box transmission, 2500 stall converter.

I will remove the Whipple and i am planning to install Twins 66mm turbos 1400max power (want 1000RWHP). Twin turbosmart wastegates and a single
tial 50 bov. This package will most likely have twin 3" downpipes. Air to water intercooler.
The problem is that i will need at least 80lbs injectors to support 1000RWHP but i can't find them with HIGH IMPEDANCE. In order to keep my stock computer the injectors must be high impedance and if i don't find them i will have to scrap my stock computer and install an aftermarket PCM able to use high or low impedance injectors.
If you have any idea let know, any comment will be trully appreciated.
Thanks,
Rafael.

 

what about the gt40 fuel rail, has i think 16 injectors

 

I heard something about using "injector drive",
That's what i read:

"Have you checked into getting a low impedence injector driver? It would allows you to run low impedence injectors with the stock ECU."

 

They make high imp 72s now, and I think you can use those with a little higher fuel pressure and you should be good. I was running the 60s with higher base fuel pressure and it was fine for over 800rwhp.

 

For 1000RWHP i was thinking about 80lbs.
But if you say 73lbs i go with that.

One last question if you don't mind Sal, what do you think about injector driver module like this :

If you want to run low imp, then you will need a driver module. I was running 160lb injectors on my truck with a drive module, but I wasn't too thrilled with how it was working so I did the 60s instead.

 

RC engineering makes 75's, don't know if they're worth the $$$ though.

 

Thanks Incogneto.

If someone knows this brand RC Engineering, please let us know.
Thanks.

 

Why not just up your fuel pressure? either by modding your FPR or going with a regulated return line system.

I know on my DD srt-4 I uped my 58psi fuel pressure to 80psi with a simple 70$ mod that went into my FPR.

Go with 60's and get a return line and up the pressure.

 

I want a safer route dude and i got good news today, i talked to Alan Injectordude.com (this guy sells injectors for the mustang community more than any company) and he said 85lbs high-impedance injectors were just released and will ship in 2 weeks.

 

160# high impedence injectors are also out. They are advertised in Race Pages magazine for around 399.00.

 

They are not high impedance dude. They are low.

 

Hey dude, try listening to the guys that have built their rides and not bought them.

Will call Venon right now dude.
Thanks for the post, i let you know what they said.

 

I'd bet that all the Venom injectors over 83lbs are low imp.
