Who is your drag racing friend? I may know him.
Happy Holidays,

Which weight/Type Alisyn do you use in your gear case?

Rage,
I just checked my oil, and my mechanic recently switched me over to AMSOIL, another good synthetic. I am using their 80W90 gear oil. Athough they rate the viscosity at 80/90, when you move the container, it acts more like a 20/30W oil.
I think they've probably (Timken) bearing tested it to what a petroleum based 80/90W oil would do, but managed to do it at a lower (true?) viscosity, reducing heat and friction in the drive. Just my theory, I'm not a chemist. All I know is it works!
Regards,
Steve

You say you just checked your oil which i assume to mean the Amsoil 80/90W and the wear/magnet debris was low like the Alisyn gear lube?

Which Amsoil do you use in you motor? Change interval?

Regards,

Bill

Next season I am going to experiment with thinner gear oil and see how long they actually last before failure. My boat is a good test bed for them with 950 plus ft lbs of tq,Smitty

Bill:
I'm using Amsoil 20W50 synthetic in the motor now. I have also used RP 20W50 this past season with good results.
I change all my fluids (drive/engine/supercharger) and oil filter @ 25 hrs.
Checking my oil meant the extra oil I keep in the garage :D !
The motor comes out tomorrow for the winter buildup.

Looks good. We may be talking soon.

Do you perform oil analysis when you change oil?

Is PR Redline oil?

Steve, after you get your engine back together why don't you drive down and let's put it on the dyno. I'd be happy to do it on a weekend. I can even tweak the ECM. Just get an 02 bung welded in your headers while it's apart. You're no further away than "Rage" is. He came down a couple of weeks ago. Sure would be nice to know exactly what power you've got.
