So I have a '68 Barracuda with a 413 C.I. stroked 360, 10:6:1 Compression, Edelbrock RPM heads (out of the box, no porting) air gap intake, holley 750, hughes cam with .248 duration, .550 lift, Mopar Performance Dist. Elect. ign and shumaker headers. I was wondering what a safe nitrous combo might be for a little extra oomph. I have a Rat Problem I need to take care of.....

150 should do it. Start w/ 100 and see how you like it.

I'd check e-bay for a used but not abused kit. Keep in mind a bottle of gas is about $70 and it takes 1 bottle to run one event.

Good lord I fill bottles for 3.50 a lb. Does everyone charge that much where you are? When I use to drive my street car to the track I had to take 3 bottles, 1 for the drive to the track, 1 to race, 1 for the drive home. LOL

???? I'm not a bottle baby I just know it's not as cheap as it used to be. Although the guy that built this engine was going to hit it w/ a 200 shot

I had a NOS Cheater systen. The kit came with 4 different jets and instructions for the different HP levels. It was a very straight forward install.

A few things to know

make sure your fuel system is cappable of handling the extra flow needed you DO NOT want to go lean

run about 2 to 4 degrees lessof timing

a built motor gets less bang for the buck

its recomended to run spark plugs a couple of ranges cooler

a bottle will last about 200 seconds.


my 71 RR with a slightly warmed up 383 would run right on 2.5 seconds faster in thr quarter on the 100 shot. I never tried any thing higher

use you head when useing the juice.. good luck


I am truckless..

Last year i run a big shot i ran 150 shot but i did go up to a 330 shot on a 446 big block if you run about 30 degrees timing and 6 to 7lbs of fuel pressure to the gas side of the kit and run 100 to 150 shot of nos and have your carb a little fat and keep your bottle pressure around 850 to 900 lbs and it will be fine but your head gaskets look out if you go to much with the shot i hope this helps good luck.

"a bottle will last about 200 seconds."

I have to disagree. If you run a 100 shot, there is no way you will get 15 passes out of it (assuming only a 13 sec pass).

From my experience, at 100 shot, you will get about 7 passes, at 150 shot about 5 passes.

I when i run 150 shot i would get 4 passes and i put new bottle in but i could get one more because you have to keep the pressure up to around 800 lbs to 900 lbs and that was in a 1/8 mile and i run 5.95 to 6.03 et .

You didn't mention what type of system you are wanting to install(fogger or plate). If interested in a fogger system, I am selling mine entire NOS fogger system, and extras go with it.
It was installed, but never used the nitrous, so am selling it off.
It was on a big block, so the tubing may not fit. But new stainless tubing is cheap enough, that with what i'm asking, still save money over new. My sleeves & sleeve nuts would be re-usable.
Asking 1100.00 for everything. I can send pics & list of items if interested.
Also have three 15 lb bottles that i'm selling. Might be too big a bottle for you, ? If interested, i'll give you more info.
Also have bottle mounts that fit 1 5/8 bar.
If interested, can e-mail me, bob at purpleiceracing@kendra.com

Pistons make a huge difference!! I would also folllow a rule of thumb and take 2* of timing out for every 50hp of nitrous you run. Start there and read your plugs and make small changes.
