Just-Emre

I should be there tomorrow.

He seemed to favor the 5 spd. I asked why and he didn't really give me a clear answer. He also felt, at least in his opinion that most of the factory driver's preferred the 5 spd too.

The 6spd is actually very heavy. I didn't weigh it, but in moving it around, compared to the AudiSport 5spd, it feels a lot heavier.

It's also a lot longer, maybe 8 or 9 inches.

It does seem to have more range though. You always seem to have the right gear, you never feel like that it's not quite right. This may be to compensate for it being a non-turbo, although with the amount fo torque it has it might be a non-issue.

The 5spd feels just a tiny bit more like you want another gear inbetween what's there. Again, I'm not sure of the 5 spd's ratio.

I have no experience with the rally 6 spd on the track. I can see its benefits for a street car. I recall reading that the rally 5 speed and 6 speed both had the same top gear which was specific to a rally. The 6 started with a lower 1st and then respaced the gears from there. So it would just be insane on a turbo S1. Its not quite like a street 6 speed where they tacked on an extra gear that would take you to a theoretical 200mph. Hence the 6 speed just meant more shifts and the car was always in the top of the power band which would have been well over 4500rpm all the time. That actually should be a very good thing if you have to left foot brake in gear around a corner. As for gearing, even my 4.11 5 speed will get the car up to about 120mph in a blink and the time between shifts are ridiculously short. 1st and 2nd are taller while 4th and 5th are shorter. 3rd is the only one close to factory gear ratio. I can definately see why he would prefer a 5 speed for what he does with the car.

Kinda reminds me of mid 80s F1. where the V12 ferraris has 4 spd gearboxes while the Turbo Hondas ran a 6 speed.

Porsche 911 used to use Mag way back between 1968 to 1971 for trannies (901) and 1968 and 1977 for engine cases. Just makes it expensive for machining operations.

Bare magnesium when chemical stripped is a light grey, but its very susceptible to corrosion from salts and alkalines when bare.

I had a really roughed up intake manifold refinished by dipping in a yellow dichromate. We did about 4 different dip times and came up with a nice gold irridescent. If left in for too long the color turns olive and then brown. Aside from the cleaning, to get that shiney gold irridescent used on the rally car finish the trick was to prep the surface with a sheen from a green brillo pad. After getting a sheen on the bare magnesium dip it. The result is excellent.

I am not so sure about intake manifold. Looks to me like regular Sport Quattro intake manifold. It could be Lehmann modified ( cooling circuit). Real S1 intake manifold look totaly different,
more like the one on picture posted. This one is from Pike car.<ul><li><a href="http://pictureposter.audiworld.com/50234/ppk.t.jpg">http://pictureposter.audiworld.com/50234/ppk.t.jpg</a</li></ul>

It does seem to always be in the power band, but with it being stroked as it is, the power band starts pretty low to begin with. Even with easy driving, first gear is only good for maybe 20 ft.

Like I mentioned in a previous thread, some car's lose their original identity. Many of the part's on mine are from different car's. Some are marked as car#2, some are car#3.

Also I know it had forest strut's to take some bump's not like the safari strut's. But then it has the tarmac big brakes. And then the 6spd with the incredibly high 4.86 gear's. I'm not sure if they were all meant to be together or not. If so I'd be interested in finding out the logic behind it. Although when you drive the car you kind of get the feeling that someone knew what they were doing to put it all together.

and they have a section in the manual that references different pre-plating techniques to give different sheens and colors post-plating. It covers beading to rough finishes and what the resultant sheen will be.

It doesn't cover magnesium as a base metal though, I'll have to ask them for advice on that.

I am afreight that you guys wrong in regards to suspension theory. Audi had few type of suspension
HOMOLOGATED from steel to alu, mag and even titanium. Type of rally dictated what suspension was on the car. With alu or mag suspension you will not go far on rallies like Portugal TAP, Acropolis or Safari.This light exotic materials like mag, alu are usualy for
tarmac ralies like Corsica or San Remo.
