tuning questions

well here are all three passes from sunday




pass #1

82n 73 fuel , 5.5 fp @ 20*

1.277
3.616
5.549
125.10


pass# 2

same tune but @ 22*

1.235
3.531
5.440
128.84


pass#

same tune but @ 24*

1.249
3.552
5.456
128.86



so the 22* seemed the happiest , but the plugs were still rich my questions are :

1- what timing should i start to take fuel out ?

2- if i take fuel out of the 20* will it pick up more then running rich @ the 22* ?

3- once the plate is dialed in what #s should i be shooting for/ goals ?

4- and then finally once i get the plate dialed in closer what is it going to take on the fogger to run low 5's ?

I would take fuel out of the 20degree setup and work the timing up from there.

Bring that thing to Texas and I will take out 300+ lbs out of that thing without changing the outside appearance.

nope , but after the 2nd pass i pulled a couple of them and the ceramic was not clean

I would start with the 22 and pull .5 pound a fuel pressure and watch the et. How much timing was in the strap at 22?

OMG STEVE IS GOING TO GET YOU FOR THAT ONE

they were ngk and they were all still intact ...if that counts

With those numbers the 22 looked pretty good. But also knowing it could use less fuel, I would go back down to the 20 and maybe add .004 to the nitrous side jet and go from there..

You are going to have to watch the plugs as well to really learn what your combo wants.. Thanks, SJ

good job bruno - now hit that bitch harder maybe youll finally beat my street car j.k happy for you bud

What fuel are you guys running with nitrous? C16? I run Q16 on motor only but was told to switch from that when I start spraying.

you can run Q16 for fuel you just need to watch the plugs/tune very carefully

Yeah, that is what they were getting at, not that Q16 wouldn't work, but for more of a safety margin run the VP N02
