knocking on n20....
What jets should I run for a 75 wet shot? (dynotune kit)
My STG2 injectors (42.5#) are maxed out bad.. And with my 40(n) / 22(f) jet combo I was knocking baddd... by 6 degrees.. Even with my timing retarded below 13 degrees...
Help me out?>
What should I be looking for?
I should be able to run a 75 on 15-16 degrees of timing according to people here on css...
Is that only on 60s? Or different jets?
Idk why I have to retard this much timing.. Any thoughts?
Plz & Thx

injectors wont really cause knock that bad..did you go with a colder plug?
plugs more important then injectors with knocking and n02
dude stop begin cheap..get a new fuel jet and some cooling mods..heat soak will kill your motor...knock..lean you out...dont be cheap you will blow your **** and i dont wanna see that happen

Ur retarded lol, take my advice, run a 26 fuel jet and forget about lol. Wet Nitrous system use their own fueling, so if it's leaning out will nitrous is on only like it is, then it's just not adding enough fuel, try a bigger jet, and it will most likely fix all ur problems, also buy me a new power inverter, so i can log ur car better since mine died lol.
I would post the logs, but forgot to save =(

Damnit.
Nobody mentioned 60#s?
Just a bigger fuel jet?
Piece of **** fuel jets cost 11 bucks here I wish I knew which one to use for the fuel so I don't buy another one and still run lean..
I have to check my spark plugs to see if I'm running lean or rich.. Which I'm pretty sure it's lean...

bigger fuel jet it is then..
So what size?
How can I just not guess it? Or be safe with the jet I decide to get?
Is it better to have an over-sized fuel jet?

I'm on a 2.9 lol and my injector duty cycle is in the 120-130% range...
DONT spray until you get more fuel..
Your injectors are probably in static (wide open lol) and you still don't have enough fuel..

lol. Drew I'm gonna try out a bigger fuel jet most likely.
Reason why is that I run fine without nitrous.. So there's no reason why I shouldn't run right with nitrous (with the right amount of fuel).. So 99% sure all I need is more fuel.. And even with 60s I'll almost be what's considered to be "maxed out" at 80%... So I wouldn't be able to compensate for needed fuel with just 60s anyway..
Jason can monitor my AFR on HPT.. So idk why Ethan is calling me retarded for that haha.
We'll see what happens.. I'll most likely try a larger fuel jet soon. Maybe a 26 or 28.

What are your jets for the 35? My kit came with a 16/28 for a 35 shot and since it was used on another supercharged cobalt it seemed to run a lot better than what I bought (a 40/22) for what I THOUGHT was a 75..
Since I already have the 28 jet (from the nitrous jet in the 35) I'm thinking I should try it as the fuel jet for my 75?
Can it hurt to run a little more fuel than a size 26 fuel jet to test it out?
