Here is an update on 228mm flywheels and 915's from Kennedy Eng. I have talked with Brett at Kennedy, and got some info on the different ring gear placement. A 228mm late bus flywheel's ring gear is .250in. short (as sandeep found out) when used in a 915, and a 914 flywheel is only .020in. shorter. The 6cyl.911/915 flywheel doesn't have a ring gear on it, instead it is bolted to the PP.(one reason the other flywheels come up short) These dimension's are measured from the stock 915 starter gear engagement point. Kennedy's conversion flywheel for a 915 to T4 uses ALL the 915 parts (disc, PP, ring gear, and TOB) these are very expensive parts. I have spent too much money on Porsche parts already.

Now for the good news! I explained what I wanted to do with my T4 to 915 conversion, and they said no problem. So, they are making me a forged billet 915 to T4 conversion flywheel that will have the ring gear on the flywheel, and will use VW bus 228mm PP's, disc's, and TOB (with one of Martin's guidance tube's) . The 228mm disc will just have a 915 center hub on it (I think Wally got one of these disc's) Of course with this set-up it will now be a "push type" clutch.
