GPL:Engines too tractable?

A question: should 1967 racing engines idle as easily and smoothly as the sim engines do? I would expect something lumpy, temperamental, and prone to stalling if the throttle were not blipped almost constantly. Anyone have any info on how these beasts really behaved at low rpm?

I saw something about idle speed in the GPL_AI.ini file. Maybe someone can figure out how to give an erratic idle. Lutrell, Dsr#74 :-) http://www2.scca.com/amateur/club_racing/runoffs/photogal/dsr-74.jpg

Why is anybody letting their car just sit there and idle?! Drive! ;-) --Keith "Coming in 2nd place just means that you are the first to lose!"

I happen to know a lot about actual racing as well as simulators, but most olderengines dled fairly smoothly. They had some minor rpm changes, but the only ones that were really hard to idle were the old dragster engines with high lift cams and tunnel ram intakes. Even they were fairly stable, with about a 900 to 1300 rpm idle fluctuation range... E-mail me if you'd like any more
