Smile Oil Pressure Test.

So i spun out the sender unit and attached a manual gauge,bled it and read it.
Cold on fire up, 60 psi at around 1500 rpm.
75 psi at 2500 rpm, still cold.
Temp gauge vertical, at 4000 rpm 75 psi .
Temp gauge vertical, at 1500 rpm 20 psi.
I'm happy, not quite what the book says, a bit more actually.
It must be the good Penrite oil.

Although I have no experience with it, Penrite has a small dedicated following in the high performance crowd. Too hard to get.

Thats really cool that ya did that Nick....thank you...too many just assume that the idiot light is gonna save em....its usually too late by then and the damage has been done....at least a little.

My old Harley had an oil pressure gauge on it (was easier on them)...but Im wondering if one could tee off the line and add an actual dial gauge....
I did that on an old Chevy hot rod of mine and ran it up to the top of the dash...I cant see why it couldnt....whaddaya think ?

I'd go electric for a regular thing, or like my Harley maybe one of those oil filled vibration resistant ones, on the engine some where, maybe the top of the left frame down tube or on top of the stock air filter. A bit of braided line perhaps. I'll look at it a bit more.
Ps I just set my mixtures again, but this time I put a dab of silicone on top of them when done. Seems heaps better tonite, I'll double check if things stay good after warm up tomorrow.

Talking

Haha, I posted a thread once about installing an oil pressure gauge. I was told I didn't need it, was going to get a hot oil bath, and I was going to crash while mesmerized and staring at the oil gauge.

My idiot light flickers on during warmup sometimes, if I let the idle drop too low while it's still cold.
