Bernie,
I seem to have omitted a few relevant facts, so here goes:
The trans was built by Carl Rossler, a real pro! Here:
http://www.rosslertrans.com/ It's a full roller, full auto race trans - no trans brake. I just put it in drive and go. If it downshifts, it does it without any input from me.
The tracks are road race tracks ranging from ~1.6 miles at Gainesville to 3.7 miles at Sebring, where I have done numerous 1/2 hour sessions at full chat. The trans has exceeded my expectations to say the least, as it is still working fine after amazing abuse.
The engine has always run cool, no problems there.
The latest cooler to meet its maker is this one:
http://www.bmracing.com/index.php?id...subcat=&pid=75 It is the model 70297 that has a 500cfm fan. The fuse blew and the fan shroud melted.
The fan and shroud are labeled SPAL, made in Italia.
Both the B&M and the Derale tech folks told me to put the fluid through the radiator cooler first, then into the add-on cooler.
I put the add-on cooler behind the radiator about a foot because I couldn't find any space anywhere else to put it!
All experience welcomed.
Tom
