[200q20v] Autox'ing and Re New toy

[Derek Pulvino]

Hey All,

Did my first AutoX today.  Definetely equivalent to a car tailored, all out 
sprint.  Some pretty cool cars down there.  One of the fastest of the day 
was a Turbo Miata.  Saw the car take off, and wouldn't ya know I heard that 
familar whine under the hood.  Asked the owner, and sure enough, plumbed 
with a turbo.  Next time around I'm going to have to start messing with tire 
inflation, see if I can't trim some of that inherent understeer.  Oh, and I 
might need to work on braking for the corners a little sooner.

My question though is...I have a real good idea that my bomb is not what it 
once was, and in the really quick back to back turning sections I noticed 
steering boost dissapear several times.  I know that the accesories are 
hydraulicly assisted, so it makes sense to me that low reserves on the 
pressure accumulator could contribute to this problem.  Any other similar 
experience or impressions?  There's no weeping, leakage, or groaing, with 
the the rack, or the hydraulic pump, but I'm not leary to say the bomb is 
not up to spec.

Survey says?

And, somewhat off topic, with the S4, I'd say yes it is punchable to 3.0 
liters.  From what I remember, the Audi 2.8 6-cylinder is based on the 
VW/Audi 1.8 liter 4-cylinder architecture (bore and stroke); this same basic 
block also exists from the factory with an increased bore and stroke in a 
2.0 liter iteration (.0.5 liters/cylinder)  Do the math and you'll see a six 
cylinder with the same setup would breath to life with 3.0 liters of 
displacement.  In fact, the next generation A4 is arriving with a 3.0 
liter-6, but it is however coming from what I've heard with a block setup 
somewhat different than the 2.8.  Pretty sure they're using a longer stroke, 
more bore, and smoothing the engine out with balance shafts.

Your question about the TT-don't believe the V6 would fit in that car.  The 
car is based on the same chassis as the current generation golf, with a 
transverse engine layout.  In order to get a 6 in that car, think Vr6.  
Somebody might be able to shoehorn a V6 in the bay, but I'd it would be a 
laborious undertaking.
