I will be running a 99 C5 with a stock shortblock with a G5X3 cam and stage 2 ported heads. It will also be running a FAST LSX 90 intake and 90 mm TB... Car has ALL boltons, headers etc...

What size injectors should I run? I was thinking 42 Ford Motorsports (Bosch).. but that might be a lil big...

I would like to keep my injector duty cycle down and NOT maxed out... Also.. the car "may" eventually get a small wet shot of juice.. 75ish...

What do you think?
I need some input on this one...

I have looked at the RC Engineering website and used their calculator.. this leads me more towards like the 42's... hmmm..

Thanks

42#ers..better to go a bit bigger than too small.And it wont matter if you get a wet shot because extra fuel is supplied through the kit not the injectors....

I'm looking at a similar setup with smaller cam, AFR 205's, and a 100 shot (unsure if wet or dry)

42#ers and get yourself a Walboro pump too.ive got a set for sale if your interested.

Can you spell out why I would need the Walboro pump? I'll look into it.

because if youre going to spray then you have increased fuel needs...and replacing the stock pump with a Walboro is a niec upgrade....if you stray wet then then its more of a strain on the pump...and if you spray dry then youll need the injectors(like the set ive got for sale cheap),which in turn means youll want a better pump as well.Its like $100 for the pump and can handle well over 500rwhp.its a wise investment.

Nice or necessary? If the stocker can handle the job it tend to prefer leaving things alone.

Do you recommend wet or dry for my application?

42s, i worked on a similar setup with 30s and it was hitting over 100% easily

for a 100 shot i think its necessary.and hes right about maxing out the injectors.Id recommend wet for you app but you could always benefit from a set of 42#ers....pm me if you want my set.....whats $400 for injectors and a pump for insurance when if something happens and you go too lean and blow your motor and now you have to spend $6000?i personally would take the $400 any day.

Yeah I ended up getting a set of FMS 42's... should be here soon... I will upgrade the pump if I do spray... It's a very good safety measure. No dry shot for me... all wet....

The hairdryer is always a nice addition. Might do one of those eventually, but cant at the moment..

the hairdryer is just a part of it....in the middle of a big motor change....should be crazy when im done....ive always wanted to be able to floor it at 70 and roast the tires
