So giving this old thread a bit of a rattle............... What are peoples thoughts on the types of variable resonance manifolds and their effectiveness? For a pair rather different exampes, Ferrari went from its previous dual length manifolds in the F360 and F430 to its divided plenum chambers wit...

The idea is to have zero toe, as close to zero bump steer and simply run true Ackerman. The reason why I ask this question is because I want to increase the track width substantially. But I will be using +50 offset RX7 wheels and RX7 wheel hubs. These have a more central mounting face than the Alfa'...

Hey KevinR, I don't have a standard balljoint to compare the long balljoint with, but I think it was close 25mm. The bump steer corection was done by using spherical rod ends. Their pivot point is higher than a tie rod end, so with a 5mm spacer I was able to get rid of almost all of the bump steer. ...

When trying to figure out Ackerman angle, the diagram below is often the sort of thing that is used to figure it out. But the diagram only looks at the top balljoint or stut top and doesn't allow for the King Pin Inclination angle. Using http://www.Vsusp.com I modeled the front suspension of my 75 w...

The V12 would have been a better fit in a JZA80 Supra..............

From Kevin's thread on the 75 IMSA car viewtopic.php?f=21&t=4115, a rather non-aluminium bearing plate in the middle of the gearbox.

An alloy steel bearing plate??? Or find out if vacuum infusing a laminated a carbon fiber component that is 30+mm thick is doable and then machine the CF to suit? Maybe would want bronze inserts for the shift rods? You could also look at making the the areas around the 2 bearings thicker on the inpu...

So either make an alloy steel 1 of go completely mad and actually create a carbon fiber bearing plate????
If it was made solid like your custon plate, it wouldn't be very light. But it would resist deflection like (basically) nothing else!
How thick is the central plate?

Measure results of the billet aluminium plate are a 37.5% increase in bent stifness.About 0.045 movement That's not bad. I aspected a little more because of the better material and the not weight saved part. An excellent improvement! Would it be worth while to make a new bearing retaining plate fro...

One question; bump steer can be corrected with additional positive caster? Idea is to reduce camber from -3,0 to -2,0 and add more caster. My long shank upper ball joints are 20mm longer than those from factory... Heres photo of some additional custom work :) Unfortunately not. I thought that becua...

I've not tested the idea, but there are cheap little PCB mounted relays that have the required drive circuitry to be triggered by a 5 volt signal. For only a few dollars and a compact surface mount design, I'd give this a go.
Look for 'Arduino Relay' on ePay.

Looking at a workshop diagram of the gearbox, the thrust loads from the pinion gear are fed into the case via the centre plate. It doesn't matter where the thrust bearing is on the output shaft, so long as the shaft, bearing mounting point and the case in general are suitably rigid. Your idea about ...

Awesome information! This is the sort of stuff, like MD's clutch housing brace, that helps the Alfa community progress and stay in 1 piece. It's probably a bit hard to get across to people in other parts of the world, but here in Aus, there weren't that many Alfa's sold. So If I smash my 1990 75 Pot...

Nice! With the springs being out there they'll definitely resist body roll more than springs in the standard positions. Remove 1 of the antiroll bar's links and see what the car is like then. If that's too soft in rear roll resistance, then you could modify the rear antiroll bar so that you can soft...

Duk: Rear anti roll bar is factory bar, I'm thinking of removing it completely since I've changed position of shocks and springs - now they are located next to rear wheels. Shocks are revalved Bilsteins to spec for 170/60 springs. Bump steer is not corrected yet. Are there any proportions available...
