im putting on my DR's and changing out the wires and plugs when my nitrous gets put in this week...was wondering what you guys think ill run at the track with a 75 shot....im hoping my kit comes with a jet for 100 but from what ive heard it only comes with a 75 jet. its NOS 05115? thanks

i was wondering what you pros thought it would run with a 75 shot or 100 shot? thanks

I too have the NOS 5115 kit. Unless you have a bigger fuel pump, then you're not going to want to go any higher than the 75 shot. 100-150 shots require more fuel pressure as well as fuel volume. So the stock fuel pump won't cut it. If you're turning 14.1 on motor...the 75 shot should knock it down 8 tenths or so. A full second might even be possible. Make sure your timing is on 9 or 10 degrees btdc. And you should run a regular style spark plug (NOT PLATINUM OR IRRIDIUM!!), but one step colder than stock. Let us know whatcha run.

Ok, now I see that your sig states that the 14.1 was without the drag radials. Drag radials usually shave off 2-3 tenths on your 1/4 mile times over a regular street tire. So maybe with a 75 shot of the nitrous and the drag radials...you could probably expect a full second improvement on your time...providing you can drive well.

The 190lph fuel pump is a great idea. You can probably go up to a 125 shot with that fuel pump. Not a 100% sure if the 190lph is enough fuel for the 150 shot though. But your fuel pressure safety cutoff that comes with the 5115 kit will let you know if it's not enough, by shutting off the flow of nitrous.

sweet thanks for the info...i really want to find a way to spray a 100 shot with the NOS system i have...DO you know id the kit comes with a jet for 100

I'm not a 100% sure if the kit comes with the 100 shot jets without buying the upgrade for the kit. But buying bigger nitrous jets is easy. Get on the phone with the NOS techline and find out what # jets (2 jets total) you'll need for the vacuum "T" & the nitrous nozzle that plumbs into your throttle body. Then go down to your local speed shop or the place where you're going to get your bottle filled and buy the two jets. Get that fuel pump in...slap in the jets...and have FUN!!
