I have mine plumbed directly into the oil system through a ball valve. The system charges to capacity at the maximum oil pressure (60psi?) while driving down the straight. In the braking zone, if the oil pressure from the pump drops, it dumps oil into the engine at the maximum oil pressure and tapering off to the empty system pressure. I have never liked the idea of putting an active control system between the Accusump and the block. To me, this just adds failure modes in a critical system. I have my alarm set at 20psi and I have never had it sound while on track with it plumbed this way. Without the Accusump I get regular alarms in hard braking zones.

I have 6000 hard track miles on my L30. I checked the valve lash and compression a few weeks ago and it shows no sign of wear. Dave builds a great engine. I monitor AFR's on the track with with a wide band and rejet as necessary. I've got 3 hours of dyno time booked on the 4th to do some fine tuning.

The 2 liter Accusump has worked flawlessly for me running 235 NT01's on road courses. On a good day I can generate about 1.1G's of steady state cornering load on a long sweeper. If you have more grip you may uncover the pickup more than I do. My L30 is a Rebello unit that I run with a set of 44mm Mikuni's. Great little track car.

I use a longacre low oil pressure warning light hooked up to a 85dB siren in my L30 240Z track car. http://www.longacreracing.com/catalog/item.asp?id=368&catid=11 If the oil pressure drops below the set point I can hear the alarm even with a helmet on. I've never heard it with my 2 quart Accusump enabled but if I forget to turn on the Accusump the alarm chirps in every hard brake zone.

A couple of questions...Are they the later "B" series and do you know if they need to be rebuilt?

I am looking for a 4 speed transmission. Preferably the later model 1972+ (F2W71B). I am located near Houston Texas. Local pickup is preferred but I don't mind paying for shipping if necessary. e-mail = steve@studio979photo.com

I used to run my su's with sm needles on my stroker. The car ran great but had very little high rpm power due to the limited air flow potential of the su's. Great torque though.

You know you own a Datsun when you park in the pits and people regularly walk by the Porches, Lotuses and Corvettes to look in your engine bay.

I didn't think of turning 34s into 39s. Anyone got a set of smaller venturis they would like to sell?

I am looking for 39 or 40mm venturis for a set of 44mm Mikuni carbs.

It was an extra that came with my car. New in the bag from Nissan. I have no need for it. I'll pm you.

I've got a brand new one if the other link does not pan out.

I am looking for a fan clutch. I need the stock, rebuildable one rather than the generic part store version that cannot be taken apart and rebuilt. The rebuildable model has bolts that hold the two sides of the clutch together.

I was looking for something more like this... http://www.thezstore.com/page/TZS/PROD/WCC/25-2060 but in the bigger 3 5/16" size. Thanks Steve

Looking for a black center cap for a 1973 240Z. The specific rim that I have has a 3 5/16" hole for the cap. Thanks Steve steve@studio979photo.com
