[T3] interesting jetting stuffs

[vwfye@frontiernet.net]

<x-flowed>well, after transfering my 1904cc motor to my notchback i have been dealing 
with a major 'lean' condition with my carbs.  the only change to the set up 
was removing the 4 tip exhaust and adding the JSC header/muffler.  This has 
resulted in so much more flow (while still being a 1 3/8 exhaust) that i 
have gone from a 115 main jet to a 130 (so far) main jet.  it has been 
interesting from a jetting a throttle response point of view.  the old 4 tip 
labored to let the motor rev to 4k rpm.  the new exhaust breaths so much 
better that i blip 4k with out even trying to.  i would like to point out 
that in my frustration, a mailing listee helped me refocus on what 'cause 
and effect' to look for.  so, thanks Tom Hansen!  Even a dyed in the wool FI 
guy can help!  hehe... anyway, if i have to go bigger on main jets, i will 
keep you posted of the changes an exhaust can make!  btw, ask toby how much 
cooler a 2007 runs with a 1 5/8 vs 1 3/8 exhaust!
