Ok so I installed I'm nitrous kit last weekend and I was wondering if I could shoot a 75 shot with out retarding any timing? I was planning on just running a br7ef plug with a coule of gallons of 100 octane mixed with 91 pump gas. Any thought on this people?

 

What are the mods on the car?

 

I keel you for asking such a silly question.

If its running normal and nothing is wrong with it, your car will have zero issues with a 75 shot. Just use the normal safety devices and you'll enjoy the extra HP.

.....But I just read your sig... so now my suggestion is to go to the dyno and check AFR to ensure you have enough fuel. You wont need the 100 octane.

 

Mods of the motor are a small cam, long tubes, 102 fast, patriot heads.

I have a efi live data logger that was planning on using with my test runs to check to air fuel to make sure its good. The car already runs a lil rich on Na tune. And I have a fpss and window swith for safety but I'm just still a lil scared to spray it because I'm not pulling timing. That's why I thought I would run the 100 octane

 

Well unless your NA tune has the timing jacked up for more power you should be fine. What is your timing at on the NA tune?

 

Think its 23*

 

I would think you'd be fine with that but dont get me breaking your engine.

 

im spraying a 200 shot on a 5.3 with that much timing... you should be fine. also sprayed a 75 for a while on my buddies 2002 ws6 (longtubes and exhaust, cai only) stock timing was around 26 degrees, it rode out fine stock fuel pump and all.

 

Ok thanks man. Good to here
