How much juice on 91 octane? I live in California and all we have is 91 octane gas here. I know it is a limiting factor for nitrous. I was only planning on using a 75-100 shot for safety reasons. Can I use more? I don't want to use race gas because the juice is for the street.
Re: How much juice on 91 octane? I run a 100 TNT wet shot on 91 pump gas. I also take out 4 degree's of timing with a timing tuner. I will be trying a 150 shot on 91 with about 6 or 7 degrees of timing out when it gets a little cooler

Re: How much juice on 91 octane? i went from 113-114 on the motor, All bolt ons / cam /4000 Stall / 3.73s ... to 127-128 with the 150 shot.
cam at that time was CompCam 224 /.581 / 112
Make sure ur not getting KR... and I think TNT recommends 100 Oct for their 150s just to warn u.
Also have a inline/intake pump. my buddy leaned out to 17.0 up top wiht the 150 NX wet kit because he couldnt get enough fuel with the stock pump.

Re: How much juice on 91 octane? Cut out enough timing, and you should be alright. Get it on the dyno, and retard timing until all KR is gone, and if your AF is good, you'll be good to go. You should be good up to 150?
Re: How much juice on 91 octane? im running a 02 LS6 engine with a G5X2 and a 150 shot wet, running 25 degrees of timing and only a little knock during the day, I sprayed yesterday when it was 108 degrees out with 2 people in the car and it still worked ok.
