Lost .5 and gained 6mph 1/8mile on a 75 shot Best motor pass was a 7.86 @ 88mph with a 1.70 60ft. Had the nos mini progressive on 50% the whole run. Its jetted for a 150 shot. Hit the spray 60ft out and went a 7.34 @ 94mph 1.69 60ft. I was impressed. Was gonna hit the 150 but was out of n20 due to a leak in the bottle heater pressure sensor. Mods are flt lv 4 4l60, yank ss3200, pacesetters and magnaflow exhaust. HSW wet kit.

When you progress the shot that long it throws your tune up all over the place. I'd advise if you want to run a 75 shot to pill it for a 75 shot and you will see even better gains! The progressive is just a traction aid for you to soften the hit for a short period of time. It looks like the shot definitely woke the car up though!

Well done, I was about to say the same thing Brandon mentioned. You always want to change jets, not use the progressor as a complete power limiter. Our controller has the option to reset the ramp after every gear, or continue the same ramp process. Not sure about the NOS one.

I appreciate it. I was having trouble getting the delay to work correctly on the nos mini. I would have it on a 1 second delay and it would delay, n20 would hit until right before second gear, it would shift and then delay 1 sec, and hit again. shut off rpm 6400, shift points are at 6100. called holley and they were no help to me. any suggestions? Like I said I was going to hit it with a 150 but ran out of bottle. Thanks for the reply!

hmmm, that is interesting. I had it on start % 50, end % 50. I figured it would be that for the whole run. Could you elaborate more on 150 150 150?

Because it was not spraying half the pill size for nitrous and half the pill size for fuel. It was giving you a 100% shot for half the time. So you were going on gain 150 hp and timing reduced, off 0 HP, timing back to normal, and cycling like that. By it doing that your engine computer is all weird thinking stuff is not working right. So its spending half the time running right, and half the time trying to get itself back to optimum settings..
Spray 75 all the way through without interruption and it would probably pick up more than what it did.

Yes change the jetting! And as for the delay what kind of tires are you running? My bolt on car runs 7.6's on motor and 6.8's on a 100 shot using FJO controller. Its set to spray from 1800-6500 shifting at 6300 and works great. HARD launches as it hits as the converter is flashing.
