As far as Spark plugs go? what are you gapped at? any problems with longevity or misfires?

Right now I am running Autolite 104's gapped at 53 and a few idle misfires. can't tell top end wise.

later today I'm gonna have a guy scan the car. then I'm going to buy some 104's and 103's and gap them at .035 and see which scans look better.

I'll let the pro's answer your question, but what mods do you have? What size pulley are you running?

I run mine at .50 with my 2.8 pulley with autolight 103's.

I'm going to start selling the autolight 103's racing plugs on the sight soon as well.

Al103's with a .035 gap. I spray happy juice as well

i use NGK tr55. when i used autolights i have misfires!!

maybe i had a bad one?? seens most use autolights but i has problems. thinking of switching but i have a surplus of the NGK now :D, got a box for a deal

well, I changed my plugs yesterday. went with the 104's at .040. scans showed 2* at the top of second gear WITHOUT W/I

I haven't touched the Hobbs or pump PSI. and with a M10 nozzle I got a max of 1*. not bad considering no pem's or DP. I'm gonna bump the hobbs to 6-7 psi and up the pump psi.

My mods are

Homemade HAI with 9" K&N
Throttle Body spacer.
160* stat
AFPR at 53psi
ubend delete
3.25 modular (american supercharger)
modified stock 1.9's
EDIT: Forgot about my DHP and of course the W/I

I think thats it. PEM's and hopefully a progresive controller are on my to do list maybe a 3.1-3.0

AutoLite 103's gapped at .045. Ive only been running my PAC alcohol kit for 3 days now so I'm not 100% confident these are the right plugs but so far no misfires or KR @ 19* advance (could only run 13* before)

NGK TR6's gapped at .055" For now. Once I get alcohol working, and my N2O kit installed, will try 103's at .040" ... with 2.9 pulley.
