as long as we arn't doing this for drag racing, who cares about the lag..
As we all know, these arn't fast trucks.. I would want one for those times I am towing my boat.. Just think, by the time you have to turn off the OD.. the turbo would be spun up..with a terbo, you might be able to do the hill in od..
And the really steep ones (like the grapevine north of la) with a trailer, in 3rd locked, not 2nd locked..I would love to be able to tow uphill at 55mph.. (the speed limit in CA with a trailer,
there are a few sections at 60, but 90% are 55)..
The turbo would do this, off road i doubt many of the SC trucks even use their SC's.. WOT in 4low.. that would be funny.. In the sand & mud, you would be into the throttle enough to keep the turbo spun up, so it would be helpful there.. just not in the rocks.. at 5psi that fat from the intake, you might get away with mid grade.. put in an intercooler, and maybe the cheap stuff..
BTW, at 5 psi boost, you should be well over 30% increase in power.. an NA moter will never see atmospheric(sp) pressure at the injectors die to the filter, plumming, and relying on engine suction to move air.. with a wastegate tweek, we should be able to raise or lower the boost far better then the SC..
Here is a page on Motorcycle Turbos, just to give you an idea what is out there..
