Yeah I was a little confused by the post as the only difference between wet and dry really is the injectors. I have a set of 42.5 # lightning injectors going in next week but I wont have my fuel pump for . . . well wenever the hell racetronix gets them shipping lol. I just want to run my 75 shot in the mean time to deal some pain to my buddies pesky modded 04 cobra

Also here are the mods to the car ( that will effect the fuel system consuption )
MTI S II Cam 224 220 581 581 116
Kooks Long tubes
Kooks catted Y
Ported Tb
FIPK
SLP Loudmouth
I also have a Meizere ewp and asp's but those wont equate to any fuel taken from the pump. My thoughts are that the pump is good to 470 rwhp right ?? A 75 shot dry should be about 50 rwhp giving me at best 450 rwhp spent from the fuel system ??

Do you have any fuel related mods? I am installing a 5177 kit on my car right now and was going to run the 100 pills on top of my NA set up (sig), I wasn't really considering changing injectors but was at least thinking about adding an inline pump. any feedback guys?

With my mods my 28.8 # injectors are at 93% duty cycle @ 6600 rpm without spray so those need an upgrade imo
When the car was stock I used to spray 125 shot @ about 1150 psi resulting in 440 / 560 rwhp/tq so I know its good to that point.

I figured id update this with some results.
I dynoed 389 rwhp / 372 rwtq with the cam and bolt ons sae . I wanted to ease into the spay and see how it looked.
With the 100 shot and low bottle pressure it did 472 / 466 rwhp /rwtq . Air fuel went as lean as 12:1 up top but other than that stayed very very good so we know no theres a bit more than 470 on the stock pump. Injector duty cycle with the 42.5's was only 53% at 6400 rpm on the nitrous so I think it will easily handle a full 100 hp dry shot with the upgraded injectors on the stock pump. Ill see how it looks at 500 rwhp next
