Default Boost and N20 Question

Well already asked how much the FI guys are spraying, but what kind of timing are you running on the spray??? are you pulling even more timing for the N2O?? Im planning only running a 35 shot for now so I wasn't planning on pulling any timing. I think im somwhere close to 20 deg. now.

35 wet shot?
I didnt pull any timing for the 50 shot.. 18* on 93oct right 5psi.

i think the rule of thumb for NA is 4* for 100shot and 4* for every 50 after that?? Cant remember exactly

I dont think your goin to feel a 35 shot.. When im in boost and hit mine i can barely, and i mean barely feel it..
Only thing i used it for was to load it up off the line in vacuum so i could hit boost faster.

Now that i have hydroboost brakes, im prob goin to up it to 75 shot just for a lil extra fun.

If you have tuning software, it wouldnt hurt to pull 4* out and work it up slowly.


How much boost are you running?

you could not pull any timing but i would run some race gas just to be safe.

when i ran 15 psi and a 125 shot we pulled 3-4 degrees and used 117 race gas, i think i could have pulled a little less but i didnt want to risk it.

I haven't pulled any timing. 50 shot dry. 19-21* IAT dependant. I can most definitely feel the 50 shot.

Well I run a lot of meth too so Im sure that should help. Im mainly using it to spool the turbo off the line to get my 60's down. since going back to a stock stall i can barely make any boost stalling it up.
