my beetle hits 250f on the oil after 10 minutes on the highway...
So lets discuss why that happens because that's really wrong.......tell us about the weight of oil you run, what distributor you have and how your timing is set, what oil pressure it's showing cold and warm, how you set your endplay, doghouse or straight cooler/shroud, tire size and gear ratios, carb, jetting, exhaust, compression ratio, etc......It'd also be handy to know where your temp sender is located and if you calibrated it.
and i'm 100% sure it has NOTHING to do with the fact I fly cut the heads .040" without improving the stock cooling system.....
hmmmm... stockish compession = normal operating temps. compression that needs 95 octane = overheating
weird huh? also, 150f pavement is normal in the south Okanagan
but if you really want to know: 10w30 oil, 009 set at 8 degrees at 800 rpm, stock dual port shrouding throughout, 50 psi at cold idle, 15 - 20 at 180f at idle, endplay? I dunno- no slop? tires are 205-60-15, stock tranny, 3200 rpm at 100kph, carbs are k-dogs running a tad fat, exhaust is bugpack headers with a mondo muffler, compression ratio- way too much, temp sender is on the pressure reg at the back of the engine, no calibration, but i'd just as soon touch the header as I would the engine block
