Start Point

[size=12]I have a IS fogger system that I bought off this forum. I need a starting point. Would 22/20 with 6.5 on the fuel be a safe start? 532, glide, 9 in converter and 4.86 rear???

I cant remember what you said the motor specks were tell us again and what ignition system do you have.what fuel are you using?

You shoulda got the tune up sheets with it.

If not there should be a serial number onit, call Steve andmthey should,have all the info you need.

no sense guessing when you have a flowed setup like that.

Imo a 22n 20f is gonna be fat, a 26 or 28/20 maybe closer. or a 22/18

Nicks too busy playin cabin boy i rekon lol.

looking for tuneup as we speak .....

there was a baseline tune in the fogger already when it went to Michigan ????

Update

It'd asking for a 40 jet.

no card , sorry I would call Steve he should have info on that intake

FYI: fat is not as safe as you probably think.

Fuel pressure will be jet dependent. Since your system is flowed the math is not that difficult. Just wait for Nick to get back to you after he speaks with Steve.

what jet do you want to start with first a 20?if so start with 20nos/14fuel that is a 6 jet spread with the 6.5 fuel psi that should be plenty fat.


but then again if it were me I would work toward 8 jet spread with 5.5 fuel psi "too fat is not always safe"

fat will get ya ashtrays a lot sooner than lean will.

Yep

Over timed and fat are what we see most of the time in failures.  We don't have any customers running anything smaller than 36's and most are in the 48+ range and they all use close to the same fuel jet.  We do adjust fuel pressure so the ratios are what we want them to be and then read the plugs from there.

what jets were in it?
