VAC Oil Pump update

Good question.

Vaio's oil pump is the most cost effective solution. I suggest contacting him and get the details. If I had a street 330 and was going to track it, that's what I'd do.

I'm planning on doing the VAC baffle and Vaio oil pump then calling it day. Go balls to the wall until my engine blows up.

Are there any problems with the VAC oil baffle? Or does it do a great job compared to stock of keeping oil pressure up?

Bump^

Interesting scenario I hadn't heard before: I talked to Jay(?) at Bimmerworld about their OPN w/ safety-wire and he said, without it, spinning out and going backwards with the clutch engaged would shoot the OPN right off.

I've got it and don't appear to be suffering any oil starvation, although I've only had an oil pressure gauge installed for one race at Barber(long right handers, no long lefts). I do still run 1qt over...

The VAC baffle works well. We do the dual sump on pure track cars (willing to spend the $1500). It gives a little more oil pressure in all situations and better defense on starvation as well.

The dual sump works in an E46?

Verifying on an engine here, but I know we have run it. I will make sure noting needs tweaking. May be a few different parts required but I know we can do it if interested.

We just mocked one up. We can make it work. Similar to the Z3 aluminum block setup.

Ha! Nice. And with this you wouldn't need an oil baffle, correct?

James, i buy a lot of parts form you, and I'm very happy to see you responding to the Motorsports & Track thread that you sponsor.
Keep it up, we all would like more of your knowledge and insight.

Thanks! I can only spread myself so thin, but I am always available via email.

Thanks for chiming in James!

If my car was a pure race car then I would have gone with that dual pickup (I had talked to Brian and Jamie about it over the phone), but I decided on going with the VAC baffle instead. I picked up some of your guys solid rubber URO engine mounts and the RE tranny mounts as well for while I'm doing the install. I also settled on VAC $300 competition oil pump... it might not be the perfect solution but I'm thinking it should work for me if they made it work for a number of seasons in World Challenge. I'm looking forward to putting everything in next week.

Is there any downside to the dual sump setup off the track?

In WC, we (and most other teams) used something custom in the pan a little more extensive than the VAC baffle. But the baffle definitely chips away at the problem.

Absolutely no reason this can't be used on the street - I thought about that when I typed it and not exactly what I meant. Better said - most people that make a $1500 investment are racers who are willing and accustomed to spending a little more money on parts that won't make the car faster.

Ha, I've got the most expensive slow car there is.

You guys don't have PCA and Ferrari club out there? BAM!

Haha, well are we now talking slow cars or slow drivers?
