Looks great, as a base to start from (next winter ......)
So a UG file would be great

in UG ??? , then me wants.... ( : drool emoticon : )

Maurizio: Why not the one-way to the brake booster? Yep, thought of that one too, have several one-way valves laying around for testing. But the problem is finding a hose (exhaust to valve) which can stand the heat. The valve I posted is somehow designed to isolate the heat. You are getting rid of ...

If you want to experiment with gaining some additional power (1-3% as they say), you can dump the vapor hose in the exhaust pipe at an angle (so there's a constant suction) and the crankcase will operate in a a 'vacuum', minimizing windage losses! :lol: Guess what I am brewing lately, I’m still loo...

Here is a lot of inspiration ...........

Believe me the three bolts will deflect.
Only I don't know what is worse, the engine torque or the rpm.



The rubber bits have a real hard life, between the bolts they are buckled by the torque and forced to fly out by the rpm.

:) I'm just plain stubborn, (that's why I stick with alfa's) so for me it just depends on the applied N/mm^2 . A plain example, how about alloy wheels....... But one thing is true looking at fatigue steel wins! :lol: But I don't want to start an huge discussion so guys take the easy and safe route u...

This kind of fastener needs a very stable material to not relax with time, alu will just not do. A good point, on the nut side & washer side not a problem but the guibo has not such a nice contact surface. Was thinking of making some supports for a long time. Now I have the TS drive shaft out, ...

You actually could just use a good quality aluminum plate of 1 mm thick. You want to add stiffness in the radial direction of the bolts and a low stiffness in the nut direction so that the plate can form and take tolerances when assembling. The trick is that the plate has a in plane stiffness which ...

I converted a 75 ts ps rack to non ps. Just put the oil out, fill with grease and put a balance tube between the left and right chamber.
I think I have seen it on several dutch trofeo cars and the milano of Greg Gordon's father?


Will have too see what it brings

OK, thanx for info. Make allowance for valve/piston clearance....not only at TDC Exclamation Checked the valve clearance in the design again and have theoretically on intake 2.47 mm and exhaust 2,34 at TDC when taking the C&B race cam, with a 1.6 mm gasket thickness, Cam Lift IN Cam Lift EX Valv...

For my TS bottom end project, I'm making a list of new parts. http://alfagtv6.com/bb/viewtopic.php?t=40&sid=ba4769e29cd773cfdf030030cf581183 is a nice list as guide. I have three questions. 1) As I'm rebuilding a 4 cil no timing belt but a chain. Do you guys replace the gear wheels of the timing...

Yes, chassis is designed to work with torsion bars! Jim's setup will give a progressive stiffness, is suspension travel > 1 cm the coil spring will start to assist. My car is mainly track use (coil-over, not RS, but basically the same): I did lower the car about 1~2 cm to deep for what I wanted and ...

Guys you are forgetting something! The soft (helper) springs only make sure your main spring doesn't float when the suspension is unloaded (driving over a bump, curb etc...). Like Mats already said. It should always be there, suspension travel is more then the unloaded main spring length. As far as ...

:D pleasure was mine. So you guy's actually got some nice wheather after all. The rain was getting less the more I got near home on my way back. The whole saturday no rain (according my girlfreind) at all and that only 150km away from the ring. Next time my car is ready :twisted: The slow lap on sat...
