Got an hsw plate kit. last time at the track i used the 75shot nitrous jet and 100 fuel cause i was afraid of going lean. car went 8 tenths faster and 8mph faster sprayin only 2nd and 3rd. wanted to jet it correctly for this weeknd but now im thinkn i should just leave it. what yall think?

 

I am very interested in this to.

 

Usually the jet chart that they give you with the kit is fat so the fact that you used the recommended fuel jet for a 100 shot and N20 jet for a 75 I'd say it was WAY fat. You are more likely to hurt your engine running it that rich than running it a little lean. I'm sure some on here will disagree, all you have to do is ask some of the "bigger"nitrous tuners and they will tell you the same thing.

You should really put a wideband in the car, start out with the recommended jetting and go from there. If you really want to make it safe and get the most out of it then learn how to read your plugs and tune it accordingly. I'll bet that it will go faster with the recommended jetting and more than likely even faster with a slightly smaller fuel jet then they recommend.

If you keep running it fat you will more than likely hurt it before too long. Contrary to what you read on here fatter IS NOT safer!

 

I think you are pissing up a rope. Throw all of this lean stuff out of the window, because you aren't going to hurt it that way. Put the right jets in it. I'm willing to bet that you could actually go lower on the fuel jet than what is
recommended.

 

im running the 35 jet in a hsw kit on a 150 shot, it is the recommended jet but it is way way fat, prolly gonna have to run a 33 or 32. we shall see next time out.

def put the right jets in it.

 

I would not recommend mixing the jetting like that. Start with the recommended jetting and throw a wideband on it to see where you're at a/f wise.

Yea got a wideband just not installed..lol..the gains just seemed right for the 75 shot so i was curious.. thanks!!
