Injector Recommendation
With my head and cam package about to go on, I'm pretty sure I'm going to be on the high side of duty cycle of the injectors. What do y'all think would be a good injector to go with? Keep in mind I want some wiggle room. In the near future I'm going to install a ported fast and a 150 shot

I'm looking to do just the injectors right now, and when I put the nitrous kit on that's when I'll replace the fuel pump.... Unless when I get the car on the dyno am I'm still running out of fuel. I guess we will have to see.
IPS what kind of duty cycles are you usually seeing on a car that has 500 rear wheel horse power? Are you seeing any idle quality issues with the bigger injectors?

What are the size of the stock injectors on a 07 vette? Will the stock injectors handle roughly 500RWHP?
I plan on putting a set of TF225s on my car.
Would it be better to get the FAST 46# Injectors (LS2) or the FAST 57# Injectors (LS2) ?
Do I need to get this too?: MSD Fuel Pump Booster
See sig for the other mods already done to my car.

With the 42 lbers at 4 bar and 500 horse power I would bet your in the 75% range and above. We prefer to stay under 80-85% for safety measures.
I know this is somewhat vague, but that is the nature of the beast. If you would like to really calculate injector sizing, us RC engineering's injector calculator to get you your target size and duty cycles based on fuel pressure and other inputs.
If you would like anyone is welcome to call in give me as much information as possible and I can spec out your injector sizes on each case by case. No charge

I'll take care of the injectors when we swap out your heads. Its a tuning issue too and not just physically putting them in.
The manners of the motron 60's are awesome and they are easy to tune.
Let me know when you're back home.
Hope all is well in the desert.

Hopefully I will be back around Jan 2010.
All is well here in the desert so far. It's getting old very quick here though.
