Hey guys, the project didn't move very far last summer. I was having some tuning issues, ended up the MAF was really dirty and throwing everything off.

Then I was having oil pan issues, still am actually. The pan I was running originally had no baffles in it so turning or stopping under small g-forces I would lose oil pressure! I took it apart a few times and built some baffles into it, and I'm still not completely satisfied. Under hard braking it still has issues. I installed an oil accumulator (like an accusump) and it helped but I want that as a back-up and not a crutch.

I'm going to cut the factory pan down like the outfront motorsports pan and try that, the lost oil capacity is made up in the oil accumulator which adds 1.5-2L.

Then I can drive it like it was meant to be driven.

Anyway here are some pics from a carshow a few weekends ago. I didn't build the car to 'show', more to drive, but one of my goals was to enter it in this particular show because it was the show we went to growing up. Sort of a rights of passage for me to have entered a car in it, and ended up winning best modified VW!

Take care

Mike

Very cool and it looks fantastic, nice to see some updated pics

Thanks! Here is another pic I found

I've got a decent tune on it right now that will run and drive the car quite well, and runs up to about 11psi. The timing isn't optimum (conservative and not very smooth) but I'm waiting for dyno time to really dial it in. The motor should be fairly reliable up to about 18 psi, but for mainly street driving (some auto-cross and some drag strip) I think 15-16psi with careful tuning it should be plenty fast enough .

I'd be worried about the tranny at 18psi, hell even Jack's killed a few with light boost Are you using Albins/Weddle gears?

1,2 gears are stock, 3,4 are coarse tooth bus gears (late splined 3-4 shift hub that uses factory 002 gears). These gears have the syncro hub welded to the gear from the factory.

Ratios are 3.78, 2.06, 1.26, .82

944 CV's

The tranny is the late 'zig-zag' case with the extra ribs on the top. I won't be running slicks on it, and if I do they will be small (7") so I'm not too worried about gears breaking.

Tranny life will depend on traction (shockload) and sometimes moreso the guy behind the wheel. I'm not one to dump the clutch or anything so I'm confident it will stay together. We'll find out!!

I just remembered theres a guy on the samba with a +400hp turbo'd honda motor and last I checked his trans was still alive.
