Remeber, if you buy one you have to get the gauge too. If not you could be running 50-60 lbs and not know it.

retarding the timing every 2 degrees for every 50 horse will keep you safe, my dad is sprayin a stock 96 vett nos cheater kit, right around 300 horse hes hitting it with and been doing it for about 6 years now. bottle pressure can be a factor also, nitrous flow best at 960 psi, so leavin the line aroun 1000-1100 is good and at the end of the run you should be at 900 or in the ball park depending on how much you spray

everything went fine on the dyno.

thank's for everyone's help.


number's where way low. something is up with my car, im thinking the transmission is eatting up alot of my power.....

ill do a write up in the afternoon.


but n/a number's my first time out was 212.38hp and 261.9trq

with a exhaust leak, and stock heads.


i fixed the exhaust, port and polish the heads, replace all exhaust valves, replace the 2 bent intake valves, still had stock spring's that where only holding 70lbs, so replaced all springs with 110lb springs..............


n/a i made 215.20 and 263.67, a gain of 2.82hp and 1.73trq.......from $500 of head work.

100shot i made 286.81hp and 358.15trq, a gain of 71.51hp and 94.48trq over n/a
(id like to note on the 100shot that im a jackass and still had the timing set to n/a timing witch was 18-19*base, because im dumb and forgot)

150shot i made 311.46hp and 398.41trq, for a gain of 96.26hp and 134.74trq over n/a, and a gain of 24.65hp and 40.26trq over the 100shot.

first run of the 150 shot was with 8*timing, bumped it to 10* with only 1-2hp and trq gain.


kinda dissapointing.
