Going to the dyno soon and I want to be able to fine tune if needd for 100 125-130 and 150 shots.

I have 52 33 and 62 38 already

what else should I get:

32 34 36 37 58 59?

Is a 125 about 58 35?

150 – 62 38
*175 – 73 38
200 – 78 46

* - This jetting is just a rough starting point
Final Jetting will need to be determined by Customer
A/F Ratio will also need to be checked

I got a little baggy of jets and jet list with my purchase. It included 50, 75, 100, 150 and 200 jets.

SY732

Me too but I have heard the jetting is a little rich on some applications, dont want to go back to the dyno over a jet!

ShaneD_06GTO

I need fuel!

PREDATOR-Z

Agreed, like way rich on mine. Used 62/38 with 12.4 AF N/A and ended up running 11.3 AF for the run.

Question, how much does owering the fuel jet from 38>35 affect the AF in fuel?
I say 35 because that jet is available in the kit.

Who did the A4 swap in your 06 C6?

Why did you swap?

The 62/38 combo is about 11.8-12.0 on the gas for me. MY N/A afr is 12.8-13.0. The 35 jet is going to lean it out quite a bit. Sometimes people forget that that extra power in a nitrous kit is really from the ability to burn more fuel.
You could also go with a 70 nitrous jet and see where your at.

or use a shorter fuel line from the solenoid to the plate like I have to.

Here is a Daves Plate 62/36 on a Totally Stock LS1 A-4

SY732

Beer did you leave the 36 in there or go to a 37?

Is that about 12.2 at the leanest point?

I would spray with the 36.

12.2 looks about right, we tested jetting on the dry and then Daves plate we combined a dry shot with the wet for a final two stage combo.

Since then I have added 42 # injectors, Headers, and a Racetronics fuel system, as well as EFI Live for tuning. We are going to revisit the dyno in May.

ND for 150 shot is 62/38
Looking at Colonel N20 files I find that they use 63/36 for same rating. I think I'll give the 62/35 a try with a bit more fuel via tuning to see where I'm at. adjust via power enrichment as needed.
Man I need to get one of these multi jet kit .

Remember the colonels jet table is based on NOS jetting and they use a 950psi bottle pressure, and BP dose make a difference in your final a/f on a wet hit.
I allways carry a numbered drill bit set with me when going to the dyno. this way you can drill any smaller jet out to the exact size you want, makes the job of dialing in a system much easier. just rememebr to allways re-mark a drilled jet.
