Naaaah, I won't be pounding on it that much, since the vehicle weight is
not enough to support the power level, unless there is enough downforce.  I
won't be at that point on the street hopefully, if I am, something is
seriously wrong (or my radar detector is working <G>).  Seriously, I am
gravely concerned about the power/weight ratio, and might add extra weight
in the form of making the sprung weight (i.e. roll cage) much stronger,
thicker, better triangulated.

I don't mind replacing clutches, if that saves the transmission.

Not sure what the specs of either are as rated from the Factory.  Kennedy
Engineering, who makes various adaptors for the Porsche & VW Bug transaxles
to other engines (chevy 350 for example) rate the Porsche unit (G50-50) to
700 HP.  I for one think that's in 5th gear, at 200 MPH.  I can't see 1st
gear taking that.  Like you said, the Porsche's make their power at the
mid/top ends, not at 1500 RPM for the most part.

The Audi 016 transaxle which is the one I have (or is it 013, I forget), is
rated to 400 HP, but again, its at the higher RPMs.  A friend of mine has a
5 cyl turbo motor that was dyno'd at 450 HP (at the flywheel), and has
shredded 1st gear when popping the clutch at higher RPMs.  Of course, this
car is not designed for what he's using it for (german made 4-door sleeper)

Good advice, thank you :)

Yes, been there done that.  However I didn't get a T-Shirt Tom, who gave
you yours? <grin>
