Gen1 Injector HP

[TexasPettey]

Anyone have an idea of how much RWHP the stock Gen1 fuel injectors can handle, with and without a fuel pump booster?

MSD pump booster is for GEN 2. I dont think they make one for GEN 1...

I have an MSD booster on my Gen1. I didn't do the install, so I'm not sure how it's connected.

The Gen 1 injectors are only good for about 520hp at 55psi. If you change your cam, add performance heads and headers. You will need the larger Gen 2 injectors and a better computer calibration. Gen 1 cars tend to run lean on the top end and get worse with modifications.

Thanks, Dan. Is that a RWHP estimate or a FW HP estimate?

Use gen2 injectors and you'll be safe at 600Hp

Dan do you mean 600rwhp. I'm running a 100% stock fuel system on my 01 and it's fine at 565rwhp.

gen 2 injectors will fit a gen 1 and flow enough to support 600 Rwhp

I would agree with everyone get a set of used Gen II injectors. Gen I injectors are 25 # injectors and Gen II are 29# injectors.

I changed mine on my car and it is only making 469 RWHP NA. It was running pretty lean on the top, after the injector change it has been fine.

Usually can pick up a set for $100 to $150 from someone who modified and has them laying around.

All used injectors should be flow checked and cleaned !!!
