Converting fogger to plate

[SlowJoe]

we got a compucar fogger kit and a nos plate. We just ran lines to the plate and used nos jets. The only jets we had was for my sniper fogger on my car. So we looked at snipper plate kit jet chart and we had the jets for a 125 shot. But the car only picked up 3 tenths in the 1/8 mile. What did we not do right any help would be great. Thx

What was the 60' time? What was your bottle pressure? What is your timing set to?

60 ft was like 1.8s i think bottle was around 900 psi and timing was lowered 2 degrees from what is was. Not sure what it was before that i will get waypastcrazy to get in on this.

[waypastcrazy]

60s were 1.8 pressure was 900 timing was 34 then 32 and then tried it at 36

That's a lot of timing for a nitrous car. Have you checked the plugs?

Also 900 psi is kinda of hurting you. You should have the bottle press at 1000 psi for optimum results.
Are you leaving the launch pad on the jug?

Based off your comments, I would say 3 tenths in the 1/8 is not that far off for a 125 shot running at 900 psi. Also if you are leaving the launch pad on juice and only cutting 1.8's, you are leaving at least another tenth or two on there.

[SlowJoe]

yes we was on it off the line. The car is all over the place got to do some work on that. I was not leaving that hard 2500-3000 rpm. Waypastcrazy and kev drove the car to and i think kev ran a 1.7 60ft with a 7.85 i think

actually 4 tenths how much timing do you recomend plugs look good they are motorcraft 32s what jetting should produce 125 shot thx
leaving launch pad at 3000 rpm nos it on a wide open throttle switch

[waypastcrazy]

engine runs very smooth no misses at all

I never ran over 26 degrees total timing in my car (pump gas) when running a 150 shot.
I can't find a table to tell you what jets should be used for a 125 shot plate kit.

Why were you guys launching so low? Because of traction issues? You have to launch harder to get the full advantage of nitrous. ( the sudden torque hit)

Up to at least a 5k rpm launch. Then you will see your true improvements

I run my timing at 32 degrees total on my 100 shot.For the setup you have you really need 950-1000 psi bottle pressure.


I will look for my jet chart and see what you should have in there

did not want to break the t5 first day at the trackand springs are shot lol putting 410 gears in while we are working on the suspension

qkjuicedpony that would be greatly appreciated

I run 38 total on motor then on nos i run 32 total. on pump gas on a 180 jet and 3922 plugs. that's a cheater kit with carb and bottle psi 950 on the line when i leave.

[qkjuicedpony]

A 125 shot should have a 55 nitrous jet and a 61 fuel


and 150 shot should have 63 nitrous and 71 fuel

So we looked at snipper plate kit jet chart and we had the jets for a 125 shot.
What jets did you use?
What car is this for?
Is it fuel injected or carb?

[SlowJoe]

it is for a 90 gt carbed. We used 61 fuel and 55 nos. Thx guys we still have some work to do.
