Re: GTV6 L-jet mods

[Joe Elliott <jee@domain.elided>]

128hp at the wheels from a 1.7 is pretty impressive.  Is this the 1.7 
boxer that makes a claimed 132 at the flywheel, or a later I-4??  As 
for what intake and exhaust tinkering can do, see 
http://www.andrew.cmu.edu/~jee/junk/other/dynoboth640.jpeg.  That 
graph shows my worn-out GTV6 when I got it, and after I did a valve 
adjustment, new plugs, K&N filter, and free-flow exhaust (no headers 
though).
