Re: reducing lag via exhaust efficiency

["Mike Miller" <JoMi@email.msn.com>]

I've got a stiffer WG spring in mine - I can spool up tp 1.8 bar in about
300 rpm - like from 2400 to 2700 in 3rd, 4th or 5th. 2nd will go to 1.8 in
under 1000 rpm  - like between 2k and 3k. The srping I have is about 50%
stiffer than stock - I seem to recall it took about 25 lbs to depress the
stock spring to a 1.625 in. height (fully open WG) and about 38 lbs for the
"new" spring.
