Unfortunately, "BluByU" sits most of the time at the CAMP, waiting to be driven. Last month, my son and I enjoyed a drive that took us out to the Portland historic races. We enjoyed the day and the track and left around 3:00 in order to make it back to my other son's soccer tournament. The six started and ran normally both two and from the race. Parked it at home and drove with the family to the game.
After family duties, when to start the six and....zzzzzzKKKK - no engagement. put the car in gear and rocked it back and forth. Tried again. This time engagement but loud clunk each rotation. ( the starter was relatively new so I thought maybe it was loose.) Drove up to the CAMP and parked it. Climbed under to see if the starter was "loose" - nope. Put the car cover on it and suspected a broken tooth on the ring gear. Called my trusty local independent Porsche mechanic and asked. Tried starting again same loud clunk - figured that it must have broken a couple of teeth. Anyway, had him check it and sure enough - broke 5 teeth in a row. Now here's the rub - He installed a new flywheel and a new starter (Bosch). THe six now starts sooo much quieter and faster than it ever did with the "high Torque" one. He told me that the high torque starters work great on high compression engines, but that he recommends the bosch starters for anything stock as they don't damage the ring gear. Now, the flywheel looks great and I understand that it can be machined and have a new ring gear welded on. (I saved it as well as the relatively new starter.) I have seen a number of flywheels with removable or replaceable ring gears and have been considering one for the new race 2.7 I have for "other" 914. Would it be worth it to have it machined for a replaceable ring gear as well as lightened and balanced? I would keep it as a back up for my 2.7 race motor -or- use it on the race motor. Waddya think? |

Mark, respect your opinion. You clearly know what's what with these cars.
My point is most guys won't know the difference until it's probably too late, and the gamble isn't worth the reward, particularly on a six or six conversion. So you save $200-250, but if things go wrong you'll have to spend $400 (or there abouts) on a new flywheel, and labor (unless you do it yourself) or a day of your time doing the repair, plus another starter which will probably not be a cheap high torque. I say spend the extra $200-250 (over the cost of the high torque) to get a starter that you know will NOT eat your flywheel (and probably at a bad time and place) and last a very long time. From my experience the Bosch starters are very durable. For most guys doing a six conversion, the extra money spent isn't going to break the bank on what is usually a somewhat spendy project anyway. I mean, what's another $250 bucks when you are dropping $10,000? I replaced a flywheel on a customer's car for the same problem, with (against my recommendation) you guessed it, another high torque starter. I told the guy when we got done, that I wouldn't do the job again. If I had an open schedule and nothing better to do, maybe. I will not put one of those on a car again. |

For clarification, I did not use another on of the "Hi-torque" starters like the one sold on Pelican's site (and in BKLA's post). We used the starter that is commonly seen for sale on eBay. You will know it when you have one because the electrical leads are on the bottom of the starter when mounted, which make little to no sense to me to build a starter that way (IMG:style_emoticons/default/WTF.gif) . I already bought the starter before I knew I had an issue with the flywheel caused by the previous starter. If I had to do it over again, I would go with a Bosch starter and am keeping my eye open for a good used one (subtle hint for anyone that may have on for sale (IMG:style_emoticons/default/biggrin.gif) ).
