Hey guys just got my SSP tranny cooler installed and tracked last night - love it! Temps never got above 210 in a 20 minute session. Question is when I come in should I keep the cooler running (will it drain the battery too much ? Mine has a manual on/off switch. That way I can start the next session at about 175-180 (or is that too low?). Sorry for the newbie question!

Not much use running it when you're not moving. Without airflow, it won't cool much.

Shawn,
His has the remote pump and the cooler has fans mounted on it.

Steve,
If you did plan to do that I would keep a jumper pack handy.

Didn't realize the fan would run with the ignition off. I thought it was "switched" on the relay. Sorry about that.

I thought he had this one:

I didn't know that had non-switched fans on it.

Once at grattan (all day thursday) and an evening at gingerman (tuesday).... and the Cooler is awesome. In fact no need to keep running just flip the switch when you are at the track. Never went above 225 despite a couple 12 lap sessions. I was running l:30-1:32's at Grattan (yes I am still learning) but topping out in the straight at 148+ (hit 150 once but the braking was a bit scary ... even with the Jhooks). I should have done the tranny cooler thing last year! As an aside but relevant point, drag strip performance is the same (keeps at 180 even after 4 back to back runs and launches). The cooler part is I just installed my custom LC2 TCM tune from Jack Cecil and my RPM's shoot to 4200 (as fast as LC4) no problem with the new clutches / tranny parts combo, Shep is definitely the Tranny whisper! I haven't launched yet as I was breaking in but now that the car has had two track days, a 400 mile drive back from shep's and a test and tune using LC2 at 2500 rpms, I think I am ready. Can't imagine!!!

Think you prolly should'a said even with MX72's instead of even with J hooks.

It's the pad that's holding you back. Think you're gonna find as you get faster, you're gonna need more stopping power than the MX72 offers. I've got a still good used set just sitting in my garage now that I've switched to the Hawk DTC-70/60s combo. Actually, due to lack of availability at the time I needed another set of 70s, I'm running 60s all around now, but really, I can hardly tell the difference. Apparently the 70s have more initial bite, but they both have the same heat range.

How's the dust on those? What kind of prep did you need to do to convert from the endless to the hawks?

 

[Goodwood]

The dust is normal for track oriented pads, ie a lot. I would say just doing lots of light-moderate braking without too much heat buildup would be enough to scrape the MX72 layer right off. Then go out and heat em and follow the Essex bedding plan.

[Goodwood]

Heck, you've got black wheels, don't you? Why worry so much about dust? I on the other hand, have the oem silver wheels, and ya, it's a royal pia to try to keep em clean!

Thanks for the information. What the temperature like outside. I just picked up a 2012 and am a bit worried about tracking as we typically run 10 -14 lap sessions but the temperatures at max can be in the 80s or 90s but are generally around the 70s. It is also a high speed track at MoSport international.

Does this typically warrant a transmission cooler install or is it usually on the shorter tracks that really drive up the temperatures ?

I ran at grattan and the temp was 70 degrees and 225 was the max, the day I was at the drag strip it was 75. I haven't tested in the hotter temps but my guess would be the max would be 245. Without the cooler 10-12 hard laps would yield 255+ easy. So I am thinking the tranny cooler is good for 30+ degrees. They way I look at it the tranny cooler pays itself back in extending fluid life if you track a lot.

Cool

Sorry for the newb question but what temps does the car usually jump into limp mode ?

Under 248 degrees change tranny oil every 18K or 18 months ; 249-284 change every 3000 miles; + 284 change immediately upon stopping (includes all fluids including diff, trans and engine oil). As you can see the 248 degrees is the magic number which is the sweetspot of the trans cooler. I would change more often but gives you perspective on the savings benefit if you track alot.
