i have the NOS dry setup and was maxing out the injectors, however i just put a cam in the motor but i still wanted to spray. Should i buy bigger injectors and have someone tune it? or should i just get a bigger fuel pump and switch out my setup for a wet kit and keep the stock injectors on?

also what would i need to switch out to get the wet kit instead of the dry kit?

 

I would do the bigger injectors and get a custom tune, also get a bigger fuel pump soon...no cheap way of getting around it if that's what you were hoping for.

 

not hoping to go cheap, just safer. Theres no one in town who could really tune it where i live. But if i could spray a 100-150 shot on a wet kit w/ stock injectors it would make my life easier

 

Check out the very end posts of the wet vs dry thread. this may make you choice a little easier. If your looking for safety, then dry is the answer, find a tuner on line, as doing the injector rescaling is easy.

If you ever plan on building a motor in the near future then i would go ahead and upgrade the injectors so that away thats one less thing to worry about wiht the motor build.

so would you spray with a cam and nitrous on an otherwise stock motor?

 

Check the for sale section for some 42lb / hour injectors. They'll do nicely for what you plan on doing.

Why not?

 

In a heart beat!

Providing i'm adaquately covered for fueling ( racetronix system or dedicated ) and the tune.

Sounds like you don't want to buy bigger injectors and you don't want to tune. Can't have it both ways.

A wet system will definitely require a tune and if you need bigger injectors with your current dry system, then you'll still need a tune after installing the injectors. If you are wanting a 150 HP shot or more, I'd say you probably want a wet system. There are pros and cons to both systems.

Going from a dry to wet, you need to get a conversion wet plate (like the one shown in the link). Don't forget to budget for a better fuel pump and fuel pressure safety switch too.

I actually already have the 42 lb injectors waiting to be installed. I think the highest i would spray is 150 shot so i'll stay with the current dry setup.
Even if its dry would i need to upgrade the fuel pump as well? or is that mainly for wet systems only?

The only thing im waiting on is someone to tune for the injectors before they go in.

 

How about just using a Boost-A-Pump instead of changing injectors or the fuel pump?

 

If you max'ing duty injector cycle above 90%, it's time to upgrade the injectors IMHO. To me a boost-a-pump introduces another possible point-of-failure into the system. IMHO, I'd do a Racetronix fuel pump with the bigger injectors. If you already have a dry kit, maybe it's time to hit the dry kit with a 100 shot and then add a 2nd stage wet kit. But, you say you only want to spray 100-150 ... you may want to chnage your mind after you spray for ahwile, who knows.

It's like someone told me ... 'if you want a 9-sec car, build it for 8's' made sense to me. I'd apply similar rule-of-thiumb in your situation. Someday, you might want more and won't have to re-do everything all over again.

 

i've already been spraying for a while now, i'll probably content to stay at 150. but im not sure whether to upgrade the fuel pump if im staying at that range w/ just dry.

 

Smarter guys than me usually recommend that 150 shot is about the max for a dry system. I know the stock fuel pump will handle a 100 shot no problem. My gut feeling is the stock fuel pump (assuming it's in good condition) "should" handle a 150 dry shot. If I were doing it, I'd make sure I had a good fuel pressure safety switch.
