Re[2]: Gas Mileage eating up!

[Toby Erkson <Toby_Erkson@ccm.jf.intel.com>]

Just a reminder, a Bug will perform differently than a heavier Squareback, 
and this includes mileage.

For a stock engine setup the stock exhaust should work fine i.e. no flow 
restrictions.  For better exhaust breathing use a dual quiet pack or a 
stinger (stingers are much louder), but beware the extra leveraging weight 
of the dual QP as it's kinda wearing on the headers.  Find a way to support 
it out by the rearward portion (the side easiest to kick) if you can.

Adding an extractor on a stock setup may not be a good idea since 
over-scavanging can reduce your mileage.  I believe I've read this but I 
can't recall the material and knowing my fantastic memory I could be 
totally wrong -- can anyone expound on this (the extractor on a stock 
motor, not the mileage part)?

I don't know what kind of mileage the FI got since everytime I fixed
something it would fail somewhere else. With my 34 ICT's I get 17 mpg and
that is without 4th gear (soon to be fixed). I also have a 009 dizzy and an
extracter exhaust with a single QP or stinger, depending on how abnoxious I
feel.
If your still using the stock exhaust you might want to replace it. It
could be choking the motor.

A friend with a Bug and the same setup but with 40 IDF's get about 22, the
same he had with the stock carb, but lots more power.
