Re: Front - Rear track width and transition while cornering.

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...

Re: Front - Rear track width and transition while cornering.

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...

Re: Front - Rear track width and transition while cornering.

Without crunching the numbers, you're spring rates will have the car with very high natural frequencies both front and rear. The rear natural frequency would be VERY high! What rear anti roll bar are you using? With the long nose top ball joints, have you done anything to correct the bump steer? On ...

Re: Race Animal ?

what did they do to make it a RWD? Surely the answer is simple! Front wheel drive, especially bonker powerful front wheel drives, SUCK!!! Traction deficient, tyre thrashing, undesteering pigs! Car manufacturers all around the world can do all they can to band aid FWDs, but you'll never see a FWD Fe...

Re: 3.0 24V "dies" after 6000rpm

It is going to be dependant on what fuel you're able to run in the car, but your full throttle, high RPM ignition timing does look pretty conservative compared to what you'd expect to see and compared with what others have shared.

Re: A Quick dyno run

By not having corrections for air temperature, humidity and elevation/atmospheric pressure set correctly or the dyno iteslf is out of clibration, it's easy for dyno numbers to off. So long as your dyno workshop is consistant in their set up, it's not an issue for before and after work. It's when dyn...

Re: Pumped Oil Supply

Everyone may be going electric, but the Alfa's electrical system still sucks. :P I'm just want to make sure I keep my head wrapped around all pro's and con's. If the pump draws say 7-10 amps to run and the alternator/electrical system is struggling to keep up with power demands befor a 7-10 amp curr...

Re: Pumped Oil Supply

I did think about something like that too, it'd be much easier to impliment. What kinda puts me off, and it's not really that bad, is its another electrical load. Having said that, it'd only need to run when the oil was hot and you could impliment a switch on and fault monitoring sysytem to run it o...

Pumped Oil Supply

With a real question mark hanging over the durability of the internals in an Alfa transaxle being able to survive any decent sort of grunt and having seen mentioned a few times (OK, maybe once...........) that having oil pumped onto key areas coul...

Re: Cool Alfa 2.5 V6 12V CNC head porting video

I always love seeing CNC porting. Especially as any sort of actual hand porting is a cr@p job to have to do................. :roll:
But those exhaust ports look huge and way too big for the ehaust valves.
