If you are doing a wet shot you should have a seperate pump and lines for it.

Dry shot=50

You can spray a 100hp shot on a stock fuel system fine. After that you need to up grade your fuel pump in the tank or add a boost pump.

The car has a boost pump, but its bad. I asked around on here and the only thing people told me was get a new in tank. They said the inline wont help with the flow.

You should look into a Racetronix setup.

Would deff. recommend doing atleast a racetronix kit for more than 100-125. I have been safely running a 125 shot for 3.5 years with a racetronix kit and injectors..

It all boils down to fuel pressure and the AFR. I recommend a fuel pressure gauge and a dyno session to not only check AFR under load but to monitor the fuel pressure drop under load through out the RPM range of the dyno runs.

Jet the shot for the max you want to spray, then check the AFR as the Dyno run progresses, watch the fuel pressure gauge for maximum drop. As long as the two are in acceptable parameters you are golden.

I'm currently spraying a 100rwhp shot (Dave's 78mm dual stage wet plate) that is actually netting me 124rwhp on the dyno with a stock pump. My stock fuel pump is pushing 64lbs at idle, I've been told it should be 58lbs.

Good luck!
