What is the container in the old battery well? Looks too small to be a drysump oil resevoir.

this may be a dumb question but it looks to have 2 master cylinders? what is the purpose and how does it work?

Travis - sflraver

I believe it is setup with no break booster but duel break master cylinders. It is probably setup with one for the front and one for the back. Kinda like a adjustable break bias valve so you can change the amount of fluid going to the front and rear but on a higher level. If you check it out closer you will see the separate reservoir for the clutch as well.

Battery well/firewall area appears to be a dry sump setup with air/oil separator.

Look closer and you will see that it has 3 master cylinders. Separating the master cylinders allows one to accurately adjust braking bias front to rear. The input shaft from the brake pedal has a pivot point, this pivot point can be moved by a cable attachment causing one cylinder or the other to have more braking pressure. One can also choose different bore diameters, front v. rear, to get a larger effect. Tilton makes a good unit. AP has one too, but it is very expensive!

Perhaps the separator, but it looks way too small to be an oil tank...

I was thinking swirl pot, but the input lines look too small.

Its a dry sump oil tank alright. It goes through the battery compartment to interior floorboard of what used to be the passenger side footwell. The little breather you see next to the drysump tank is part of a self cleaning catch can. The system works very well.

The dual master cylinders I think are required by Grand Am and other professional sanctioning bodies. The brakes are 993TT Big Reds with Pagid orange pads.

Travis,
Just reread your 2nd post about the balance shafts. In my post dinner fog I misunderstood what you were saying. You obviously know the engine bay of the 951 better than I do.

clubracer6

what were you trying to sell it for when it was for sale?

Sloth

The lowest we had it listed for was $50k with a fresh 3L turbo engine... in the end we figured for what we have invested we may as well keep it and enjoy it.

SeaCay

OK. Got any closer pictures of this area in particular, and the engine bay in general??? (POST MORE PICS!!!!!!!!!!!!!!!!!!!!)

Sloth - great car ! ... congratulations on your newest Porsche !

My 951 is beginning its way down the slippery slope this week to ensure its future trackworthy potential.
New tires, waterpump & timing belts/rollers, just a little basic maintenance !

Sloth

Thanks all for your interest. As requested here are some additional pix, will try to get a few more up tonight...

These engine bay shots are a few years old, but the general package is the same...



Refreshed engine bay...In addition to the cosmetics, destroked 3L, and the revised oil catch system, it looks like I picked up an extra vacume line on the BOV.

Interior w/ radio, adjustable brake bias, fire system, AF meter, Stack dash... not seen is the gel battery and the bottom of the oil resevoir in the passenger footwell. The doors and rear wing are from Crawford Composites, the dash is also in CF though I am not sure who made that part (Crawford?).


About the balance shafts... I understand they have been reworked to make them lighter.

Kurt

In a word...sinister!

MitchB

Not to continue to bug with questions, but...

The rearveiw mirror(s) - the one(s) on the door - any idea where those came from?

Car looks great...

SeaCay

Can you explain all the connections on the drivers side of the intake Plenum? There looks to be 4 or 5 bosses welded up with various hoses protruding from each. There is also one on the back. The two up front look like a vacuum source for BOV and intake air temp sensor.
