Is it true these injectors are basically useless since they dont offer injector data charts with them?

I have created data that work pretty good with the Fast 65 lb injectors since we have used them in many of our builds.

Even with that they will never run as good as the Injector Dynamics, ID-850s.

I experience it Daily.

ya i understand that. I have a customer that brought me these for his maggie and cam 2010 Camaro. We just installed the lingenfelter twin pumps kit and am unsure if i should put these in or if i should just see if the stock maggie ls9 injectors will be enuf.

LS9 injectors will support it, but they'll be maxed out. The FAST injectors will never function as good as injectors that have had true characterization done.

I wasn't sure if LS9 injectors will support 600whp...which is probably right around where this car will be. Thanks for your help DSX. I think your the one helping me on hptuners as well.

DSX · 06-22-2011, 01:29 AM

Yes, that's me. They won't go up to 600whp. I usually see them run out at 500whp on return style fuel systems.

You can jack the fuel pressure way down at low demands by copying the FPCM settings from a CTS-V, but that's a cheap trick to get around the issue, and they still don't have the correct voltage offsets to work perfectly clean.

ls9 injectors are at 100% at 6k rpm. ted do u have any data that i could use. I'm sending you a pm.

52# at what fuel pressure?

The FAST 65s are rated at 4 bar.

What is your fuel pressure doing?

I have run them to a little over 600 RWHP on LS3 with 58 PSI to redline with an MSD Voltage booster.

Email is Best.

I was asking because adding my cam to my SCed build I was thinking I needed bigger injectors.
