okay thnks 4 info,i am also running 19s and my 60fts are 159,and i am using nx plate system do u think it will handle 125 shot?

and this thread has been hijacked!!!!!!

 

[sweet tooth]

yeah but i like your time better are you using a slick or drag radial

 

[Tim2002GT]

Thanks! I am running MT et street radials.

As for the original topic, most will say up to a 100 shot is safe with the stock tune. Anything higher and you may want to adjust timing and fuel.

 

[sweet tooth]

what that mean?

I don't know of a Walbro pump for a returnless system. Is your car a pre-99 that has a return style system? If not you pump is probably the problem.

 

[Tim2002GT]

They are Mickey Thompson drag radials.

i have a tune right now 4 nitrous but want 2 go 2 a125 next year,i am using a mt street radial,hey what kinda intake manifold do u have?

 

[Tim2002GT]

Still using the stock intake. No need to change it until I do some more serious engine mods.

 

[sweet tooth]

Jay C and others running 19lb injectors... Have you guys had any problems with the 19's maxing out?

I know the fuel isn't being supplied from solely the injectors, but 19's seem to be near their full efficiency even on a full bolt on car, and almost certainly a cammed, or heads cam car.

I bought a 21lb MAF with the intent of swapping in the 21lb MAF and 21 lb injectors just to gain a little margin of safety when I'm in the upper RPM's spraying.

Well, that makes me feel better that it's fine on the bottle. I know the amount supplied to the fuel solenoid would be fine, but I was worried about the injector themselves not being able to supply "enough" fuel while spraying, if they're getting close to maxed on just motor... if that makes sense.

No problem. Hope it works out for you.
