Im only at 6lbs and want to go to 10lb but will only do it once I figure out how to keep the IAT's down! Currently at 190 at the end of the run.

 

Thats excellent compared to my situation. Are you intercooling?

 

I have an STS with a small inline IC along the frame. I see about 135 deg on an 90 deg day after a few WOT runs. With the Meth It goes down to about 90 deg IAT. This is with 9 PSI boost.

 

Here's a log of my 0-60 run in A-tap. Those IAT's are scary! In fact
im going to get the meth kit ordered tomorrow. Ambient is about 85.

Those are some nasty IAT's! I was climbing as high as 180 before I installed my upgraded heat exchanger for the Radix. The original H2 one is smaller than the regular truck version. My IAT's are comperable to BlownChevy's now. I need to do a log of a run to 90 or so to figure out what I'm seeing on the top end now.
