Hey, I think what some are referring to is the bore to stroke ratio, which
has the affect of making an engine characteristically more torquey or more
revvy. Audi motors are long stroke, small bore motors, which makes them
really torquey and not very high RPM motors, where as an F1 motor often has
twice the bore of the stroke! Realistically, you don't need to be concerned
on its effect. If anything, the increased displacement is readily welcome.
As far as 300hp, I don't believe you will be able to achieve this as long as
you are running CIS, without supplementary fueling, practically speaking your
limit will be 250, and that is on a good day. If you are lucky and your 5kt
has an MC not a KH you could be looking at 225 HP with a simple ECU upgrade.

<< If you recall I wanted to take the turbo charged engine out of my rear
ended 1985 5000 S Turbo and place it in the 1986 4000 CS Quattro. I am aware
of the site with the change over to turbo but my question is this.
I want to take it as close to 300 horse as possible, planning on a
complete rebuild I had noticed some comments on the size of the bore
affecting the RPM or on how high the RPMs will go.
I guess is can the wrong piston, bore and cam affect the rpms? This is a
do it my self because I cant afford a mechanic type thing and I want to do it
right any input would be appreciated.
