The total system on my car is 900+ HP capable and did not cost a lot.
I'm not rich either.

Now thats some juice

I was thinking of what you were saying about low compression ratio i can just get low compression forged pistons and new rings... Im putting the new crank i got forged eagle 3.48 stroke and k1 forged rods press pin tho...do u know of any good buget nitrous low CR piston for my build?

Detonate...yes its a bad deal. Most of the problems I've seen where caused by a fuel pump issue. Very important to build a "fail proof" fuel system. If your fuel pressure varies you will melt parts. A stuck solenoid will cause thing to get pretty exciting also.

ya i will my next build for sure!
i just had to deal with what i had already built...so i was thinking nitrous would be my best bet for low buck hp...is the 100hp powershot fixed plate system good? or should i just get adjustable plate system?
Thanks for the tips

okay...so when i use nitrous put race gas in and when i want to drive it on the street then what? can this nitrous race gas motor run on pump gas??
this is what i really want to know

vinniekq2 Maybe I wouldnt know what to do with the math,true.Maybe only you know what to do with the math?
I say the following statement should not be posted for us stupid people ,as you are calling us.

vinniekq2 fb,you should post the laws of physics and formulas for those of us that do not know,thanks

When using nitrous and 10.60:1 cr and it don't matter where or how much or how often,, you want fuel that will not detonate.

What you can actually get away with, epends on a lot of factors. If you have to ask,,, you are best to not skimp on the quality of the fuel in the tank, when- and how ever using nitrous.

Cause when you get it just a little bit wrong. $$$$Its not going to be pretty$$$$.

I built my dedicated nitrous real street pump gas nitrous motor with a intended conservative 9.8:1 cr just for this purpose.
Reliable and powerfull goof proof running on nitrous, on premimum pump gas. go real fast without hurting parts. (I've been doing this a long time and have the trophies to prove it.)

You are on/near the practical naturally aspirated edge already for pump gas. Get used to putting good stuff in the tank when ever you run nitrous on that motor.
The money you spend on high octane gas is well worth it- if engine life matters to you.

With nitrous, quality gasoline is your best friend.
And wether you have a stock block or what ever else will not change that.

The key to successful nitrous and supercharger engines is staying well within the laws of physics.
Engines stay together when ever you do. And fly apart real quick when ever you don't.
The quality of the fuel used is most critical. Race gas is cheaper than pistons.
Alight.. so since my CR is higher a small shot of nitrous is more efficient...I was thinking about a power shot system fixed shot I've heard mixed stuff about it...I wasnt planning on spraying more than 150 to be honest with you..But yes! I will use race gas when using nitrous....I know run the carb little fatter and retard the timing...But when using race gas on a street pump gas motor.... does it effect anything else?? do i have to re-tune the motor for this?
Thanks again

prostreet6t9 Trophies are pretty easy to come by in Bracket racing.. The "heads up" classes have the fastest and best cars.

prostreet6t9 There's some real good Nitrous guys over on the yellow bullet site and they have a lot more experience. You might hit them up over there.

Bird cage the inner parts of the car.
It's not stock fox everything has been done .. i'll post pics up soon

The block will take all kinds of nitrous power. So will the crank rods pistons etc.

What no engine component will take is detonation for long. If you want trouble free racing on nitrous
run it on 110+ octane race gas. Detonation is you enemy. Quality high octane fuel is your friend.
The cam is small for a max nitrous effort.
So I dont need 1.5 gal cell....just run straight from my primary cell another fuel pump and use race gas...pretty simple I guess.
