I'm the proud owner of a drivetrain out of an Xr7 5 speed.
I'm looking at installing it into my 88 Turbo Coupe, making it a super turbo coupe. This car is in "24 hours of LeMons" races, where you take a 500.00 car (value of car and modifications) without safety equipment, then cage it, add race seat, extingusher, cutoff switch, etc., then race, anywhere from 14 to 24 hours.
Anyway, I'm looking here for advice on making this engine last for an entire race, if not several. I was thinking about pulling a few degrees of timing and decreasing boost, via an underdrive pulley. If I could run it on e85, that would be a bonus, but no tracks that I've been to sell it, and I rarely see it for sale in the mid atlantic region, only western pa and west...
Does anyone have info on pulleys and belt combinations for 10%, 20%, etc underdriven?
I know the head gasket seems to be a weak point, but the guy I'm getting the engine from had just gone over the top end, including head gasket. I'll also be putting fresh oil into the SC. Should I go synthetic? Mfgr. and weight?
Thanks for your time.
