=======================
But it was a very useful mod for the DSM folks. If I remember this
correctly, and I'm sure I'll be corrected if not, the first gen. turbos
flowed more air in the upper revs but had a little more lag before boost
built up. The 2nd gen. DSM turbos were smaller and had less boost lag
but also didn't flow as much air in the higher revs so they just
basically pooped out earlier than the motor.
So putting the 1st gen. turbo on the 2nd gen. motors netted more top end
potential and since that's where we prefer to spend most of our
autocrossing time the lower rpm compromises would/could be dealt with by
judicious use of the shifter.
So, once again the turbo guys sorta get screwed.
Thank God I'm not one of 'em. ;^)
See you on course.
