I too have considered a 20V engine for my '85 ur-Q for some years. After
looking at the cost and complexity of the conversion and the fact that
the Pro-Rally guys have no problem in getting 450+ reliable HP from the
10V engine, I concluded that, for the street/strip, a reliable 300-320 HP
can be achieved with the 10V at far lower cost. This is what I'm shooting
for with the ur-Quattro Engine From Hell project. 320 HP would be 2x
stock. That's a nice number. :) I've just about given up on the stroker
idea though, too high a cost for a relatively small benefit and reduced
reliability and engine life. I will be going with a large bore increase,
possibly to 2.4 liters. Most of the other power/torque increases will be
through improved breathing, big boost increases, the existing S4 turbo
and Stage II IA CPU. I'm looking at a SS tubular header, substantial head
work and intake manifold work and/or extrude hone, possibly a cam, etc.
Mixture enrichment will be supported if the stock fool system cannot keep
up with flow requirements. A larger or more efficient intercooler might
also be part of the package, testing will be the determining factor here.
Existing electronic monitoring of knock and mixture (not closed-loop)
will also be supported, as well as, posisbly, inlet and exhaust temps.
