Re: Racefire is done...mostly!!
I'd have to get some data on the trans temps, that being said I also race in manual mode and we have the tcu tune. I feel it's easier on the trans to hold the gear instead of having the computer kick down a gear unnecessarily, time will tell if this is in fact the case. My ECT never got above 235 and my IAT's were 10 degrees above ambient all day. The car is set up almost the same as yours, we have it set just above max. The chassis sheet shows ride height, it was measured from the bottom of the fender to the floor at mid wheel.

Re: Racefire is done...mostly!!
I'll take some pictures of mine if you want. I'm using 255/35/18's on the front and rolled the fenders. (no understeer!) The rolling tool wouldn't clear the calipers and I was too lazy to remove them so the job isn't perfect but most don't notice the shortcut.
I removed my supercooler and went back to stock and my IAT's are more or less the same. I'm thinking perhaps my I/C pump is weak.

I should have said that I was shocked you're only seeing 10F over ambiant. I figured it was a typo.

It took a while to find the "after" photo. This is with me in the car, small battery, no passenger seat and 1/4 tank of gas. When I get the car on a level spot I'll measure the height to the top of my fenders.

Re: Racefire is done...mostly!!
I've got a buddy with an E55 AMG and he only reaches 140º IAT's at 150 mph approximately. I've gotta figure out why mine are out of control. Timing gets pulled from around 24º BTDC to 16º. 10º over ambient is a dream number for me. Do you have the thermal coated intercooler?

Re: Racefire is done...mostly!!
I was using Tighed 1's cooler which is similar except it's single pass. I took it off around a month ago to see how much my ECT's would drop. They came down 5º more or less and my IAT's went up 5º more or less. Another reason for removing it was to have space for a transmission cooler in the front. I'm still going back and forth on that one. I have a new I/C pump coming in the near future. Eliminating the possible causes.

I have Rob's and I'm seeing 15-20F over ambiant under 60mph, then 25-35F over between 77-85mph.

Ok, got off my lazy backside and measured the ride height. This is with the passenger seat, full size battery, 1/4 tank of gas and 40 lbs of tools in the trunk.
Drivers front 25 1/8" Passenger front 25"
Drivers rear 26 1/2" Passenger rear 26 3/8"
