<VV> Re: 65 vs 62 Turbo

Hi Eric.

	I do get boost in second.   Most likely, I'm compensating for
lag in timing and ignition.  I think you did hit the nail on the head
with displacement/turbine size, though

Query ... do you find the 62 comes onto boost sooner (e.g. has less
lag).  I have had two 65s and now have a 62 and I find the 62 to have
much less lag.  I get some boost in 1st, more in 2nd, and maximum in 3rd
and 4th.  On my 65s, nothing till 3rd.  The 62 seems more tractable and
easier for daily driving and I really don't think it has any less
performance than the 65s (it does have the advantage of no smog at all).
It may be that the smaller engine is better matched to the turbine size
and exhaust size in the 62.  For the bigger engine they did not increase
exhaust size although for 65+ the turbo is different.  Curious if you
find the same.
