Conversion trans?, What the heck do the V8 guys have to use Options

[alpha434]

What are the V8 guys using. I know a guy locally who runs a Hewland 5 sp. What does everyone else run?

And do you guys all align your engines laterally?

Thought you guys might be interested in some developments on the Audi 016 transaxle. For a mid-priced, moderate powere level (400hp or less) trans, this would seem like a viable and appropriately priced option. I'm no transaxle expert, but following the $$ tossed around for converted 915s, 930s, built up 914s, and the plethora of non-porsche options - this Audi box sure looks like it should fit into the picture somewhere! From the GT40s.com board: http://www.gt40s.com/ubbthreads/showflat.p.../0/page/0#57684 The "news" is a new lower ratio R&P set will soon be available (and under testing now) making this trans better geared for a V8. From my engine speed vs road speed plots, this new ratio spreads the gearing over the 930, with slightly shorter first, and taller 5th. With a 26" tire it runs 2000rpm @70mph. A $4K fully rebuilt trans, with a Quaife (and your core), that sounds to me like a viable option. If it will really support 400hp & 350 ft.lbs reliably, it could be a bargain! Maybe the perfect "mid range" transaxle option? Jeff

The main advantage to the Audi 016 transaxle is it's availability and cost. Though I imagine at some point they'll start to become scarce, salvage yard prices are in the $300 range. This gives plenty of room for rebuilds, upgrades, LSD, etc. Kennedy does make the adapter plates and clutch/flywheel assemblies (except for Gen III SBC's). HP capability and durability I feel is not completely settled, as most users are GT40/Lola MkIIIB replica builders that likely don't "hotrod" them. My guess is 400HP, but it depends a great deal on how you drive them.

Under my encouragement, I directed the GT40 forum members to John Steadman of German Transaxle of America (GTA) who was willing to persue a taller ring and pinion effort (it originally started as a retro of a 951 R&P to an 016). Fortunately, one of the GT40 Forum members stepped up and funded the development of a 3.22:1 R&P.
