What do you think I should run w/ 3.4, 104's, 180*, 3" DP, CAI, 1.9 rockers, ZZP PCM? Impala SS is the car. Trying to get into the mid 13's!

I wouldnt run this combo before getting full headers. fwiw I know a guy with the same combo as you mentioned but with pacesetter headers and STOCK rockers and he is getting around 3-4 degrees of kr...wich is not good...i am thinking the 1.9 rockers that i am about to put on his car will help a lot with that issue along with tuning his pcm for him...should be fine then.Originally Posted by spidamanSS
as for mid 13's...i my self am in the 13's now...the mods in my sig is what it usually takes....you could chage it up a little though like for example...
instead of the fs intercooler get the shortstack and run the 3.2 (i wouldnt go much lower in pully size with a ss though)
or replace the 1.9rr (leave stock ones on) and the fs ic with an xp cam.....just some examples...with the above combo you will blow up you car before it even thinks about mid 13's...with the above combo you would probably run a 14.6 because of all of the kr you would have...

A 3.6 pulley is what you should run.

Just say no to a 160* thermostat.

I made my mistake with the 160...both posts well put indeedss

There are still a few people running 160's. Back before the wbody group had tuners and other means of KR reduction, it was one other way of controlling knock. There are many more options now, without the negative side effects.
As far as the SS and mods, I have first hand experience. Even with headers, DP, 104's, 180* 1.9 rockers, CAI and some small items, I could barely pull off running a 3.5 pulley. I could run nearly KR free, but had to run too rich of an AFR to quench that KR. Rich AFR= slowor slower than it should be.

I ordered a aeroforce scan gauge to help monitor my KR. Not too sure how much I have now. I actually went to track not too long ago and actually pulled a 14.2 @ 99 mph. I will definately pick up the headers though. I also am considering the SS IC. Any recommendations for monitoring KR closer?

May i ask what dods you had to pull that off? and That pretty much does it for monitoring kr...at lreast you have something...good investment...

For monitoring KR the Aeroforce is a great choice. To go along with that, mod appropriately and tune with some cushion built in.
When going with the SS IC get the best FMHE you can. If buying the kit from ZZP consider calling and having them upgrade you to this ZZ Performance
if piecing together a SS IC kit consider this Air to Water Heat Exchanger
