Losing my mind... Group: Members Posts: 2,476 Joined: 26-May 06 From: Charlotte, NC Member No.: 6,073 Region Association: South East States |
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 |

My only beef with the 901 is that when you approach the 300HP threshold, 1st gear becomes a weak point.
You effectively have to treat it as a 4-speed and not use 1st gear anymore. Surprisingly, this has been much less of a hassle than i thought it would be. But my car is driven on the street on a regular basis. If it was a dedicated AX or track car, i would have switched to a 915 a long time ago. In fact, i have a 915 sitting in my shed that already has the RP flipped and was prepped by Bill Pickering to go into "The Beast ™". I'm going to add a LSD to it and fab a cable shifter (already talked to McMark about some options for that). My (stock) 901 has held up just fine for the past several years, but like i said, it's mostly street driven these days with the occasional AX and track day. So the stress put through it does not compare to what you guys are doing. (IMG:style_emoticons/default/popcorn[1].gif) |

(IMG:style_emoticons/default/popcorn[1].gif) The Beast or the V-8 car? The 915 he'd built for the V-8 car had all the great stuff built in. If he build another one then it probably has all the Wevo stuff as well. In any event you got a great transmission Andy. I still think it would be worth the nose bleed to figure out how to use a boxster transmission. And my logic stems from the most basic element, i.e., shifting. The cable shifter on a boxster is magic. Night and day as compared to a 901 or 915. But the deal killer for track guys would be availability of different ratios. The Spec. Boxster crowd don't change them (rules), so no one is doing much sourcing there. Maybe some other format does and has discovered someplace that is making different gear sets. The other element (unknown) is how the boxter transmission would do with more power pushing it. The Spec. Boxster guys are all less than 200rwhp. Longevity with the boxster transmissions is pretty good. Bill Pickering had over 6000 race miles on his before it broke. |

It came out of the same stash as my 3.6L motor and if i recall correctly that was supposed to go into the Beast as well. (IMG:style_emoticons/default/idea.gif) |
