Re: Adrian’s lightweight Giant Killer 2.0
820Kg's???
That's INCREDIBLY light for a steel body car that isn't the size of a shoe.
Need some pics.
See the Alfaholics have made a carbon fibre body for the 105 GT Junior.

Re: V6 12v Individual Throttle Body
How's your 3D printing game, Z-man?
Design and print a decent plenum chamber in nylon. Just make sure there aren't any large flat surfaces.
It might look a bit like a dogs breakfast, but you don't look at the plenum when you're driving the car.

Re: "Patches" MD's Final Racing Project
MD, I think there also needs to be emphasis on a pumped oil supply for the ring and pinion gears, rather than relying on conventional splash/carry lubrication.
Same thing for the main output shaft bearing that wears the thrust load from the pinion gear.

Re: "Patches" MD's Final Racing Project
Structurally reinforcing the transaxle to keep clearances correct, does sound like 1 of the most important thing that can be done. Making the main bearing plate from a block of alloy steel like 4140, me thinks, would be a very good idea. Having a pumped oil supply with, at a minimum, a feed line for...

Re: Driveshaft driven Alternator
I've thought about it. And had similar ideas about putting the starter motor down there, too. But it doesn't look like there's enough space down there for it, without doing some pretty nasty modifications to the body/floor. It would be pretty cool if magnets could be embedded into the clutch flywhee...

Zamani,
I reckon I found that picture on Mendes website for IMSA Alfa parts. It's been in the Alfa pics folder a long.

Re: Steve's 3.0 24v supercharged GTV
Dropped spindles would certainly improve geometry and travel too ! I do have two sets of front spindles & hubs, but I've never felt brave enough to trust them being cut up and re-welded to give the necessary extended lower section. Perhaps instead of drop spindles, look at doing an upside down ...

Re: 24v swap missing info
With regards to inlet manifold design, I'd suggest that you look at very capable normally aspirated engines. Notably the Ferrari 458 and the 991 chassis Porsche 911 GT3. Both make about 125hp/litre and the Ferrari engine achieves a BMEP number of 15+. Importantly, neither of them use ITBs. If you co...

Re: Which would you choose and why?
Does anyone know of a suitable liner material other than grade of cast iron that usually gets used?
If a stronger, stiffer steel type of material could work as a cylinder liner, then it might be more suitable for a high stress application even with a thin wall thickness.

Re: Which would you choose and why?
How far could the capacity of the 2 litre motor be taken? With 2.2 or more litres of engine and a well sized (as small as you could get away with) turbo, you'd broaden the torque curve of the engine noticably. Really speeking, if you were able to add 10% more engine capacity, then you should be able...

Re: Which would you choose and why?
Going by what Jim has said, you might aswell start with the Holden (GM) 3.6 litre engine. All aluminium with continuously variable valve timing for all 4 camshafts. Jammed into the now dead local Commodores, they move those barges OK. Modified for more power and in a much lighter car, they'd make de...

Re: Which would you choose and why?
Got a friend with a 420hp turbo TS powered 75 street sedan. His words : "Mostly undrivable./unusable power". Without knowing a lot more about it, I'd guess he's got a pretty sizeable turbo on there. Probably of the GT30 variety? Fairly sizeable turbo on a fairly small capacity engine does...

Re: Which would you choose and why?
I've asked similar questions in the past. Obviously a turbo'd 3 litre V6 will give the highest average torque, even if peak HP is kept the same as a 2 litre. If the car's weight is kept within reason, it would be effortlessly fast pretty much everywhere in the rev range. Effortlessly fast in a strai...
