How are people able to put a size 3 pulley or smaller on your car?? I understand tune tune tune and scan for knock but dam I got all the goodies plus SS inter cooler, Xp cam, bored throttle body, and getting full headers next week... But zz performance said after I dyno tune after headers are on I shouldn't drop past my 3.25 pully...

 

Every engine responds differently. Also you might need a larger intercooler if you are just running a short-stack.

 

Gen V or Gen III? I'm on a 3.1 with hardly no knock on a Gen III with stock cam... so with any cam I could drop under a 3.0.

 

Gen 3

 

Full size IC? How much timing at WOT?

Edit - nvm I saw you have a short stack. Bigger IC is the way to go. I dropped from a 3.4 to a 3.1 and took the timing back to stock with adding a full size IC. Keep in mind, it took me getting my heads ported to run a 3.4 pulley (Had like 10* of KR before, the heads knocked it down to blips of KR)

 

Yea I see what you saying but when I hear people say they got a 3.1 pr smaller pully I'm like what they doing I'm not

 

Ss ic is holding you back. Tune is magic as well. Also are you top swapped or originally supercharged? Na bottom ends have higher compression which will make more power without dropping as much pulley size.

With same exact mods on a car:

Higher compression=bigger pulley
Lower compression=smaller pulley

Still make near the same power just one makes more with engine other makes more with the blower.

 

No I'm supercharged.. Dale jr edition and yea zz performance said they could tune it to make it more powerfully after headers... And before anyone asks yes it's tuned up turbo tim does every one of my tunes from the dyno

 

And ok the SS intercooler might be holding me back I can accept that thought

 

I also have mixed feelings on zzperformane tunes. I've heard some are ok and I've heard some were very poorly tuned.
