If you were running a 12-25 HP shot on a 15 lb bottle.. Man, you'd have ALOT of nitrous to play with

a blow down tube is required to run at the track. 70 shot is fine on the d15, run atleast premium, retard the dist 3 degrees, and you better run 14's on street tires

soo.......where's everyones nitrous videos????

anyone anyone???

1BADEGDC2

so i didnt retard my timing, i dont know how, i did a 75 shot and on drag radials i ran a 15.5 ... i sprayed in all gears too! i also ran some ngk plugs, they werent cold plugs, i think i did alright. on the 1st run i bogged, i didnt launch high enough, and same thing on the 2nd exept i did a lil better, but still bogged, i only got 2 runs in 3.5 hours, it sucks! but i think i can get it in the 14s with a lil more practice and tuning!

1BADEGDC2

so on the way home i raced another car, and when i was racing i noticed when i hit the nitrous it seemed like if i was pushing the button on and off, kinda like if it was stuttering, the car would pull, then kinda slow down, then pull again, anyone know what this is? i pulled the bottle off for now, thanks for all the help

brandenj

no 7th gen folks running nitrous on here

pgpbubble

if you bogged, on spray, and didnt retard timing.

1BADEGDC2

did you do a compression test on your motor before you sprayed it?

Why would you install nitrous and not take the proper precautions, such as retarding the timing and running colder plugs?

bertsb18hatch

i have a few nitrous questions if anyone can help me.right now im running a b18a1 with b18b1 head, crower 402-a cams, crower valve springs and retainers, blox intake manifold, blox 70mm throttle body, jdm 4-1 header 2.5 collector, cold air intake, xenocron 255 fuel pump, fpr, golden eagle fuel rail, stock injectors, 12 lb flywheel, and b16 tranny. i have a zex dry 75 shot kit installed on the car my question is the 75 shot ok to run if i change the stock pr4 pistons for a set or pr3 pistons? that will be bumping my compression from 9.2 to 10.9 with my setup.also what should i retard the timing to? zex says retard the timing 4*,also i have a friend who has a set of flat top pistons, and i was just wondering if they would be better or the pr3 pistons for nitrous. any help would be appreciated

From experience... My 302 was built with uber cheap (like $7.00 a piece) Badger hypereutectic pistons (non forged)

It was sprayed for YEARS with a 100 shot and was fine. Kinked fuel line and 150 shot got piston #1.. otherwise it would have continued to work just fine.

BUT, it was tuned properly and had the proper components (MSD Ignition, colder plugs, had 2 fuel pumps in line, ect)

SO, from that... People run 75 shots all day long with stock engines. you'rs is obviously not stock, but with the proper precautions, I don't see where you'd have any problems.
