How big of a dryshot can I run on my car with my fuel system? I have a walbro 255 fuel pump with stock injectors with mods in signature.

 

well the 99 has 26# injectors so with that engine im guessing 100-125ish whats the duty cycle on the injectos

 

With 26# injectors on a H/C car you have got to be leaning on them hard already. I think if you used some 42# injectors a 100-125shot would be safe with your setup. If your going to drop the $$$ for upgraded injectors I would get some 60#'s and a Casper electronics Voltage booster for your fuel pump since you already running a 100shot wet....your walbro could use the extra juice to help it meet that demand.

 

You are probably already pushing them pretty hard...definately need bigger injectors to put any decent size dry shot on.

also +1 on What's the DC is already?

 

Im not running the wet shot anymore. Its just going to be a dry shot. Not big either. 150 at most.

 

I would go with nothing smaller than 42#' ers......but if your going to have to buy new injectors get some 60#'s cause you never know what future mods you may add to the car, there is no tuning problems with the 60's from what I have heard/read.

 

Would the injectors be maxed out with a wet kit?

Wet shot doesnt use the injectors for the extra fuel.

The dry shot does.

 

I was just double checking. Thanks

 

You could go up to 200 on the stock injectors if you go boost referenced and drill the nozzle out with that fuel pump..Anymore and Id say upgrade the injectors. This would ask for upgraded rails, boost referenced regulator with a 1:1 spiker.
