3.4 or 3.5

[oneil.GTP]

i have ssacs, 4" open cone, zzp tune and few other bolt ons. i dont have my own scanner but could borrow one from a buddy if needed. i wont be going further than a 3.4, its not in my intrest.

main question is how big of a difference between the 3.4 and 3.5 besides the obvious? i dont race, jus would enjoy having that extra thrust. would rather go with a 3.4 but im guessing a 3.5 would be better since im not scanning all the time, correct?

ive scanned with my setup on the stock pulley with no kr. so.. 3.4 or 3.5?

If you have a MPS...just go with the 3.4"...the difference in pulley size from a 3.5" to 3.4" isn't going to really make that much difference. All I do advise is scan scan scan...because a few degrees of knock on a 3.4" is about twice that on a stock pulley.

good deal, was hoping they were somewhat similar. if anything i could jus get both and figure out which one works best, then sell the other.

and which vendor has the better pulley? every vendor claims to have the best, but i know theres got to be a difference.

thanks blue

zzp...not that I like to make them out as a good company or anything but they do have a good MPS system and it works with Intense's I think too...plus pulleys are cheap and they sell used pulleys on their site too...but if you buy the MPS it does come with one pulley.

or run a 3.5 and maybe a degree or two more timing?

Or a stock pulley and a BILLION DEGREES OF TIMING

i havent purched one yet but was looking at the intense mps but havent made a choice yet..either way sounds like they all run about the same?

and when you say more timing..im guessing that has to do with the pcm? meaning i need a new tune, or have it tuned into my current one? i dont know jack about tuning lol
