After trashing my crank and flywheel at Portland this year, I have been busy in the shed doing the nessasay modifications to my old case so I can run a stock 2.1 WBXer 76mm stroke crank with bolt on full weight flywheel, now that shouldn't come off!!.

Shimo at Dunhams cut the rear main bearing saddle so I can run the std WBXer 3 piece bearing, all the other bearings on the T3 crank are the same as Beetle, I just had to modify the oil gallery for the bearing and make thrust washer locating tangs in the case with a small dremell and it is ready to go in.

The engine assembles just like a normal crank with a bit of care not to loose the inside thrust washer out of its locating tang, once the end float is set and the flywheel is on this in not a problem.

The engine is now all assembled and in the car with just a couple of small items to be sorted.

Here are a couple of photos of the WBXer crank in a T1 case, you will see the crank is not counterweighted , T3 cranks are a lot heavier and stronger than a stock T1 crank and don't suffer from crank flex, the bearings on the engine I pulled the crank out of had done over 200,000 Ks and the main bearings were still good enough to go another 200,000, and the case was perfect.

Sweet ... now it just needs a buggy body to go in :>

How hard will you rev it David?

It will probably see 7000-7500 rpm like the old crank did. time will tell!!

Hpoe to see you there Dave,wouldn,t be a drag meet with out you.

Cheers Col

Hi

You can buy 200mm flywheels to bolt straight onto the T4/WBX crank now from CIP or Jake Raby.

I think the WBX was redlined at 6250 rpm from the factory.

I was going to dowel in between the flywheel bolts if I had any issues on my WBX.

I did a counterweighted WBX crank and the 5 dowel set up for a racer some years ago.
It held up very well without a wedge mate but he used some pretty spiffy bolts I recall.

I read in europe a fellow using a stock 69 crank and light parts
expects reasonable life from his 1603cc engine
using as much as 9000. (n/a ran 11.58!!)

Although the short stroke and light reciprocating parts helps a hell of a lot.

Great stuff Dave, goodt to see you back in action.

Wonder what the heads looked like?

Nice.................a semi factory stroker

Got it going yet Dave?

Yes Dave, in and running, although I have only driven i out of the shed.

ta dave

Beck

looking good

Was thinking about redoing my 1776 with one of these cranks, so I'm very keen to see how it goes...
Best of luck with it Dave...
