nitrous + 305 = not that bad

Well i finally got my n20 hooked up and wow.

im running a 100 shot on my 305 tpi and here is what I have raced so far.

*1996 firebird lt1 ,auto, 4.10 gears
By 1 car
*1995 z28 camaro lt1 6-speed header back exhaust
By 1 1/2 cars
*1986 buick grand national turbo, intercooled
By 1 3/4 cars
*1999 GT 4.10's, exhaust, cold air
By 1/2 car

I have yet to lose, It kinda feels good after being picked on for so long about this whole 305 thing now they are getting it back by getting smoked by it.

305 tpi auto
1.6 rollor rockers
3.73 gears

Re: nitrous + 305 = not that bad

What all did you do to your fuel system to run a 140 shot? How many miles are on your car?

Cause I have thought about a 125 but I really dont know

Re: nitrous + 305 = not that bad

Stock fuel system, and 52N/28G jets in the fogger nozzels. Car has 52K kilometers, which is about 32K miles south of the border. I've pumped roughly 25 10lb bottles into this motor, and the compression is still fine. Melted a few plugs at 10* advance before I brought it back to the factory 6*. Just remember to go on and off the button at full throttle

Re: nitrous + 305 = not that bad

Sounds like you should be running in the 13.7-14 range for the quarter.

Re: nitrous + 305 = not that bad

nitrous is definately worth every penny

a friends old 85' LB9/auto Trans Am went 14.9 with only a catback and a cone filter in place of the airbox. on a NOS 125shot it rocketed to a 13.1 at 103mph

power adders are the way to go
