Is this going to be too much ?? Its a 2002 and its a dry 5177 kit .

Hell no. They can handle way more than that.. You'll be more than fine with a 75 shot.....

Since you're running a dry kit.. Just make sure that you upgrade your fuel pump just to be on the safe side. Walbro 255 will take care of that for you.

Thanks for the replies .

I chickened out and didnt spray it but its going on the dyno saturday so Ill spay 75 on with the wideband on there and see how she looks.

Ill keep you posted

I would be more worried about the injectors before the FP.

JoeDirt

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

JoeDirt

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 ??

Yep, I did the same before my blower. Just check the AFR.

This is what I want to hear . . . what fuel mods guys , my 42.5's are going in . . . whats the stock pump going to take ??

I was able to make 487 rwhp on a 150 wet shot. And the stock Fuel Pump.

I am spraying an open line on a 98 z with just a cut out. I think a 75 will be ok

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?

JoeDirt

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.

Ken, you are probably going to be on the edge. Just make sure you are hooked up to a wideband when you first try and spray it.

Thanks Ryan I was thinking the same thing, I guess I need to also find out where Alan has my timing set,etc.

JoeDirt

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
