the motor has 120,000 miles and only has an air box and shorty headers and cat back. the motor made 320 and 340 to the ground. i just bought harris speed plate kit for it. my girlfriend wants to go bigger. i am new to nitrous because i always build the motor first then use nitrous. i use a 200 shot on a built motor, but my girlfriends car has nothing. injectors, valvesprings, tune, what else.

 

In terms of what you need for a quality nitrous setup please go through this thread and do some research

Other then i really would not recommend spraying a 200 shot to a basically stock high mile motor. I hope you have another motor ready to go in because you will more then likely break it. I wouldnt recommend going much of a 100 shot if you want to keep that car running for a little while longer.

 

does your gf know anything about nitrous? as he said do some research and rebuild your motor. 120k is really kinda high miles to begin spraying it. I dont recommend it either

 

With that kind of mileage on a stock motor and that size shot you need Jesus















J/K it may last a few passes. Mine has about the same mileage on the motor itself but it has forged pistons and arp bolts. I've gone thru countless bottles on a 150 wet and I am going to step it up to a 200 by using a 50 dry. Not sure how long it will last but I guess I'll find out

 

i saw a compleatly stock camero (not sure what milage) go a 12 flat on a 200 shot, not once, but twice. The car still runs (suprisingly)....

 

Good evidence of why you dont spray a stock car with that kind of shot. 12 flat is an aweful ET for a 200 shot. a 100 shot can get you a low 12 second time slip.

 

I would agree. I can pull 12's all day long on a 100 dry shot......
so the 200 shot guy on stock has something not right, or not tuned.
I am moving up to 150 shot to start the season, and ending the season on a 200 shot.. this all dry...

I am planning on 11's for the 150.. and as for the 200...

LOL...
hoping low 11's... we shall see I guess.. But I also am spraying a
stock engine... has 50,000miles on it....
3.73 gears...

 

thanks guys, i just needed proof from others because she wanted a second opinion. you guys said what i already told her.

 

it would be helpful to compile a list of the guys who blew the #7 or any other one but more importantly to know what timing and afr they were on and the size of the shot..

 

he didn't have it tuned, didn't have colder plugs, didn't change anything. He had bought the car about a week before, borrowed someones kit, and ran it. I had no part in it, the guy was a friends friend (if that makes since).

 

Instead of 200 try a 175 wet shot, I was gonna spray 200 in a 94000 mile motor, but just got a cam and the 175 shot. I can not believe how much this engine can take, I plan to get an intake and lt and rod bolts next and hit 600hp. The numbers on the signature are on stock intake and exhaust, However get a fuel pump, a dyno tune.
