Default 100 or 125 dry shot

well i have good A/F for both i think. On 100 im around 11.6 A/F and 125 im about 12.0 A/F. My tires suck bad and im in the process trying to get some Nitto Drags. How many of you are running 125 shot dry?

Go with the 125 shot if you are pulling the correct amount of timing for it. 11.6 is very fat!!

I was told to be around 11.6 A/F. The 125 shot is about 12 A/F. With the 125 hit it goes, i think in the near future i will probably just go ahead and upgrade the plugs, injectors, fuel pump and hit a higher shot. Right now 125 hit is the highest im willing to go. The timing and A/F is set up for the 125 shot as we speak on my car.

11.6 is wayyyyy rich. **** gets hurt more from being too rich in nitrous applications than what people realize. You are dumping all that fuel in the cylinder and fuel will not compress.

at 125 shot im higher then 11.6 in right about 12.0-12.5 so im running a 125 shot for now. If i upgrade my injectors and pump with a re tune i will definitly go higher but for now the 125 is doing ok. I havent sprayed it for a week so i havent looked at the a/f since.

Have you checked you injector duty cycle? 125 shot of dry on stock 26 lb. injectors and stock fuel pump when you already have additional boltons and making 350 HP to the wheels could cause you to be on the edge adding nitrous.

One hiccup in one of the injectors could be bad! 12.0 to 12.3 will be fine 11.6 is to rich in my humble opinion, however reading your plugs is best!

Good luck and be safe.

I meant to ask, on a 125 shot what do you guys think ill be at the wheels and what mph would that be about. I know it has alot to do with tires, driver and suspension and all but should i be around 121-122mph in the quarter and about 425-430rwhp with a 125 shot dry ?
