• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

So what size next??

Just got done putting my ssic on my gtp and I have absolutely no knock at all on my 3.4 pulley with 17ish for timing at wot. Current mods are
Ssic with ported lim 3.4 pulley
Headers with a zzp catback
K&n intake
Plugs are NGK tr6 gapped to 0.53
Zzp pcm currently might be ordering an hp tuner

I'm wondering if I could get away with a 3.3 pulley possibly or mabye even slightly a 3.25. I would really only be running it at the track. Most of the time I will be keeping my 3.4 on. I do have an aeroforce to scan. Highest octane on the street I can get where I live is 91. The track I can get 104. What's your guys thoughts?
 


local here was on a ssic and a 3.2, i tuned him to 18º wot kr free. 3.2 pulley is about maxing the stock injectors, id not go any smaller.

install 104 plugs gaped to 0.50.
 
Might look into a 3.2 then and look at picking up a new set up plugs. Thanks for the advice Scotty. Wouldn't be where I am without some of the people on here.
