I'm running 150 on my lt1, somebody runing more that 150 on stock engine?

 

I ran a 175 shot on my stock motor for 2 years

 

Me too

 

I ran a 175 shot for 1.5 years and upped it to a 200 shot for 9 months

 

200 did you used retard, race fuel or something?
why 9 months, it's that what your engine last?
did you felt a huge diference betwen 150 and 200?

 

no retard no race fuel. NGK TR6's gapped at 35. I was in colorado and I wanted to see how fast she would go. My motor is fine, leaks oil out of every seal but it still runs fine. I did notice a big difference between the 150 and the 200. I took it off because I wrecked my car at the track, so I pulled the motor sent it to get the body work, paint work done and sold my nx kit. I have a direct port lt-4 intake for the new motor. 200 is doable, and I did it on a stock rear end, on dr's

 

cool, i'm going to ty it next week i will let you know my time reduction with the 50 increment, actualy im runing 13.06, hope to be on 12 highs

 

what shot are you going to stop at?

 

Me three.

 

i did a 200 shot for quite a while on a stock shortblock. had ~11.2:1 compression, already making 425rwhp before the nitrous, 92 octane, and no timing being pulled. no problems other than when i decided to give it hell one night since i had a full bottle i needed to empty and i didnt care about the motor.

as always, just dont screw up your tune or max out your fuel supply and youll be fine. also dont spray for much more than ~ the equivelant of a 1/4 mile run at a time without a break or the rings can expand and butt together since the stock LT1 ring gap isnt as wide as needed for extended nitrous use with a large shot. if the rings ends touch youll break the ring lands. fwiw took me about 4 runs on the street back to back in a row non-stop to make that happen on a 200 shot. broke all 3 lands

 

Am I understanding you correctly?

You ran 13.1 while spraying a 150 shot ?

 

which isnt too bad considering the car is stock..

 

stock with a 150 shot should get at least low 12's unless you aren't at sea level

 

I 2nd that

 

yes 13.06 with 150 shot and 4.11 rear on BF drag radials, maybe it's a lot of time but i have seen that the tiimes change a lot on diferent tracks, almost .5 of seconds! so i dont care much the time if i can see the mustang with my rear view mirror
