Re: Autodelta Sprint 6C
Hi Joakim - not sure if anyone has mentioned it in this thread, but the prototype of the Australian Giacattolo (with the Alfa V6 engine) was mated to a ZF transaxle, as used by De Tomaso etc. They only dropped the (slightly sensible) Alfa V6 for the totally bonkers Holden V8 when Alfa were unable to guarantee supply of their engines to Australia.
As has been said above, the Renault 30 transaxle has been used on any number of GT40 kits, but has never been coupled to an Alfa V6 to my knowledge. It's strong enough for the job.
I know you would like to keep all the bits Italian (I would too if I was about to embark on the same project), but there is a bit of latitude given that Rudolf Hruska did virtually all the engineering on the 'Sud?
Given the general German flavour then, and with ZF transaxles too expensive to contemplate, a possible alternative could be the older style (80's era) FWD Audi 100, which would also keep the engine in-line for better weight distribution. The gearcluster is the same as the Porsche 924 transaxle, but with a clutch/flywheel bellhousing. The Audi 100 transaxle is popular with mid-engine kits in the US, where supplies of the R30 transaxle are limited.
The Alfa boxer transaxle is a lovely piece of kit, but it is delicate, particularly in 5-speed form. I think you need a stronger box to handle the torque of the V6, unless you can make the chassis very lightweight (you're going to have to weld in a fair support structure where the back seats are.
Alfanauts are GO!!!
