RE: GTV6 L-jet mods

["Michael S. Sweigart" <ms@domain.elided>]

I plead the 5th on how high she revs. But for sh*ts and giggles, here is the
ad from the previous owner stating the extent of the engine work:

== Engine
        Race Prep -- (Red Line 8000 rpm)
	  Auto Delta pistons
        MSD Ignition system
        Engine ported and balanced (Static & Dynamically) to within .5 gram
        Auto Delta Autocross CAMS (runs smooth as silk)
        Custom Exhaust, headers, and cross over
        Optional Nitrous Oxide injection system
	  Heads ported, oversize valves
*it also had a ping control unit (controls ping for NOS use I suppose) as
well as other MSD stuff that I ripped out.

Although I can't verify much of this work done, it will pull to 8k cleanly
although I have probably only done that once or twice. Woody from Alfa
Performance Center said it was the fastest GTV6 he has driven, except for
one. I'm sure the engine will be torn down one day and we will all really
find out whats inside...but for now...who wants to go for a ride? <insert
evil grin here>

Well I want to know, how high do you actually rev this beast?  Are
you serious about 8000?  That seems nuts.  But what do I know?  (I
suppose if you have aftermarket connecting rods and valve springs,
it's really not that unreasonable.)

To answer your question, yes.  Tachometer quirkiness is a theoretical
possibility, but I've never heard of a tach *over* reading by that
much.  Mine over reads by 200RPM up to ~3500RPM, but by the time I
hit the 6400RPM limiter it's *under* reading by 200RPM.  I suppose if
the PO messed with the ignition  it's possible that some kind of
aftermarket ignition system has been configured to work with a tach
from a V8 car and is consequently making your tach read 33% high, or
some such nonsense, but I think that's also highly unlikely.
