I'd like some opinions from the general peanut gallery. Is it worth the cost go to a 915 transmission over a 901? What is the benefit, if any? And, what's involved?
How about a Boxster S transmission? I've heard stories that a 915 is a pain to install, and doesn't every really shift well. I can't comment since I've never driven a 915 in a 914. But, with the bigger engine we now have, is it something I should be considering in the future? Being that I can get a complete 901 for cheap, and already own 3.... I know nothing about the Boxster S trans, other than a 6 speed with cable shifting would be very nice. thoughts, comments discussion? thanks |

You have a modern motor so a more modern gearbox makes sense. I would think you would be much faster with a modern lsd. would you ever add that to your boxster transmission, and also would you ever change gearing for a big track like watkins glen or vir?

The Audi box I'm running is already very tall. It was geared for the 12v V6 with a redline at about 6k. With the solid lifter conversion on the V8 I'm using, I should see 8k easily. I'll be shaking the car down at Spokane County Raceway. I swear it's got the longest straight of any track in America. If I get bored half way down the straight, I'm ordering an 01x from Europe. A tranny built for a V6 TDI should be more than tall enough. |

A tranny built for a V6 TDI should be more than tall enough. What kind of MPH will you see @ 8K RPM with the gearing in the 012? If you don't have the ratio's, give me the three letter code; I may have it in my files (somewhere). Are you building a track car, or street car? For my street car with an LS1/01E, I get 202MPH @ 6K RPM calculated in 6th....not that it would pull it nor would I ever attempt it in a 914! Andys |
