Open Coolers

[JohnRW]

I don't think folks realize how hot differentials can get, especially with Salisbury type limited-slips. Adding coolers should be a minimal impact considering all that can be done currently within the ITCS. I mentioned this awhile back and plan on running one regardless.

So...you disagree with the the current rules-set, and you'll just disregard the ones you don't like ?

What other rules might you rationalize away ?

You've been building that Volvo for many years, and while you've never turned a lap, you seem to have all sorts of problems with it that others don't. Dana 30 rear end, big axle tubes out each side, holds lots of oil and has a reasonably big surface area to dump some heat. When I was racing a 142 with a Dana 30 solid axle, I had all sorts of issues (gearbox, engine, etc) but never a problem with the diff. None of the other Volvo guys with that same axle seem to have overheating diff issues. A friend with a "flat-nosed turbo" 240 rally car had occasional diff & axle issues, but he was running ballistic power levels in a difficult (pro rally) environment, far beyond what IT-legal has to deal with.

Most likely, you've picked the wrong class for your project. Feel free to build a GT car...the rules are right there in the GCR...you can modify and add all sorts of whizz-bang stuff, legally.
