IAT's play a large factor, non intercooled I was lucky to see 12 degrees at WO with the intercooler I have ran as high as 22 with no KR on pump gas. To be honest though I dont seem to notice much difference between 19 degrees timing vs. 22. I run 19 on the street.

 

what happens if you program in more timing? you sound as if you are stuck with 12deg but i dont understand what is holding you back from running more timing.

 

I have a 2.75" pulley/9psi and run 17.5* at wot. No KR.

I dont have meth. Just the Radix I/C.

I ran 21* on my last tnue with no KR. I backed it off because I need this motor to last a while. I'm tired of swapping them out.

 

You said your IDC was 100% right? Is this with the meth or without? You need to lean it out if you are at 11.4 AFR and 100% IDC. Either start spraying meth to compensate for the fuel or get bigger injectors.

 

your loosing alot of good cool air to your ic with that stock grille on there also...it helped mine when i changed out the grille to a wide open style without the chev emblem and solid braces in the middle....the heat is your main problem...if your iat's were cooler you could run more timing...you could even go to a second ic under the first one like moregrip is running... that would take care of your problem...

 

yeh, 200* IAT just isn't good. It is the root of all evil here.

 

yea im running meth with dual nozzles but only spaying washerfluid. with the 2.75pulley im running almost 12lb's so i want to down size to my 3.1 instead and then spray 50/50mix on meth. and then maybe retune and see where i'll be with IDC and timing as well. and yes this is with the meth spray

 

have you troubleshot your IC pump? are you sure it's running? I mean 200* is crazy. I have the 2.8 and I understand it can climb REAL fast, but just curious.

 

well when i turn on my truck then open the cap on the resevior on i/c it's circulating

 

im thinking on going with 60pounder's and see where i'll be
