Don't most big rig trucks have turbocharged engines?
Yea I was referring to the slow spool up of typical or should I say, old school, turbo gas engines. Higher RPM boost, makes more sense to me for a pass car than a truck. A truck needs boost early on, as diesel trucks do.
Yes I understand there are about a dozen factors affecting boost or spool up time. Mine have VGT, or variable geometry turbocharging, which varies the direction the exhaust gasses actually hit the turbo vane, allowing for faster spool up, AND higher boost pressures as the RPM's climb.
Didn't realize the DI reduced detonation. I guess it makes sense, the fuel cannot PRE DETONATE if it's not in there until time for spark.
