=>Patrick,
=>
=>As you already know, i have the exact same setup in my Rabbit.  I 
=>mean exact 
=>(even to the flywheel).
=>
=>However, I've also noticed that the car isn't as fast as I 
=>thought that it 
=>would be.  I know that I was suppose to do some tuning on the 
=>weekend but that 
=>didn't transpire.
=>
=>With respect your numbers, you must remember that the factory 
=>numbers are based 
=>at the crank...the dyno you ran was measured at the wheels.  So I 
=>would say 
=>that you're dyno numbers are an improvement BUT not a significant 
=>improvement.  
=>I've been trying to think about how to improve them BUT I've gots 
=>a coupla 
=>exhaust leaks right now that prevent me from doing anything further.
=>
=>Maybe someone else can point us in the right direction....I hear 
=>that a 272 cam 
=>will work wonders in this sorta setup.
=>
=>HTH

=>Sal
=>67 Peugeot 404
