I'm getting my car tuned today and i want to jet it for 125 shot. does anyone know what size jets i should use? i have found 57n and 31-35f. NX website just has 100 shot and 150 shot.

Thanks!

come back and update us on what she puts down

BT03mach-1

i will. I'm going at 2 today. mods are no cats, vararam and b&b bullets and 125 shot.

friday at the track i ran 12.0 @ 123 2.0 60' with a 100 shot and no tune (i know not good) on street tires

spray a 150

Use two stages, first at 100 and second at 150 and you will enjoy it, after that you will never run the car without it. Don't worry a stock motor can handle that without any issues, I did it with a stock LS1 and my car went 10.60et with no modification to the motor.

i'm about to install a 125 shot in my car..

i was hestiant about the stock motor it has 100k miles but after some reading i think my motor should be fine for some time to come

jaglmm

is it typical for a vette to run 10's on 150 shot only..

G*DDAMN!!

wow, is that torque reading right?

Looks pretty lean on the hit.

BT03mach-1

he said its because it sucked the fuel out of the fuel rails and the pump had to catch up. i think he called it a nitrous spike? something like that.

yeah the torque reading is right. i dont know why it wouldn't be

turbotuner20v

Sometimes if the magnet or clip on the rpm signal wire skips a beat the tq reading will get wonky... that's impressive that you're making over 620ft-lbs of torque... it looks like it's occuring through the lean spike though, so that makes sense I guess.

Have you checked your plugs? I'm curious how the motor likes that ~500rpm lean spot w/ such high cylinder pressure. Was your tuner concerned about that behavior, or is that length of a lean spot normal for nitrous?

throw a bigger shot on it, and let it eat. Might wanna check your plugs. btw which plugs are you running?

my stock ls3 lasted forever and never died until i decided to upgrade

tr6 4177 gapped at 33. they look fine I'm going to put in new ones before i go to the track Friday.

dicky
