I used some of my buddies jets at the track yesterday and was wondering how big of a shot it was. They were NOS jets 67 nitrous and 39 fuel. My Cold fusion calls for 73 nitrous and 37 fuel for a 200 shot at 950 psi. I only had about 750 psi when I ran it with these. So if anyone can tell me how big of a shot I was running I would appreaciate it.

NOS
67 n20
39 fuel
750 psi.

Thanks

 

well i use .063/.033 for a 150 rwhp shot. and that put me in the 12:1 a/f ratio. so, i'd guessitmate about 175 rwhp.

 

Even with 750 psi? I am just curious. Thanks.

Also is that at the flywheel or rear wheels?

 

it's still a 175ish shot. with the bottle pressure being low, it would make it go richer than what it would be at 950 psi.
you may have been down on power in the 20 hp range???

um i put rwhp.

 

OK, so I was probably somewhere between 150 and 175 range.

Sorry, I didn't see where you put rwhp.

Thanks

 

no problem.

 

Hey BAKED I take it you finally got the trans back in the car. What did it run? Bluecat tuned my car in February and I remember seeing yours sitting in his yard.

 

i doubt it was anywhere near 150 hp at 750PSI. At that PSI the nitrous is still in gasous form for the most part, gotta get the PSI up to get it change to liquid nitrous, which is what you want.

 

With those jets let alone that bottle pressure no where near a 150 , let alone a 200 shot.

I am glad to hear that it wasn't that big of a shot. I still have my stock rearend, 3:42's and all. With an easy launch (2.1 60') My best was 11.2 @128 I was happy with that and now I can't wait to see what it will do with the 200 jets.

Z28/2002 Yea, I finally got it in, we worked our asses off trying to get it ready for this event. Bluecat is pretty damn slick isn't he.

 

probly rich as **** with that low bottle pressure
