LT;DR?They cool better alright... At idle. When driving the cooling difference between a painted black intercooler and a non-painted unit is basically the same.
Found that already, many of them aren't in stock etc. I'm talking about a kit(s) that could be made to create jumper harness' combinations etc. that I could find from a reputable vendor that has them in stock :D
In Jafro's video he's using a '90 case with the '90 gearset on his 6-bolt just as a point of reference. In truth I wish/hope that you *can* use the '90 gears in a later model helical case. Can some/any engine builders or high hp (with motors that have withstood the test of time) fellas chime in...
It's simple.If you have a case that was supposed to have helical gears, use helical gears. If you have a '90 case designed for the spur gears, then use those. The cases were made/machined differently, thus using helical gears in a straight cut housing is a no-no, and so is using straight gears...
Old thread here, but I have some info to add courtesy of your GVR4 brethren. Specifically, a Mitsu TSB that says "Don't use helical gears in a straight housing, and don't use straight gears in a helical housing".NO.: TSB-92-11-002 REVISION 2DATE: November, 1992MODEL: See BelowThis...
