someone correct me if I'm wrong, but I believe the round style has more filter area and is superior. I'm only going by what I remember to have read, so please don't take what I say as gospel.
It would seem a lot of weight could possibly still be removed:
Remove all glass and replace with Lexan. Remove all window power motors, cables, brackets, etc. and replace with simple lightweight frame that the Lexan attaches to with screws.
The Hayabusa guys use the airbox flapper circuit in the ECU to control a relay that turns nitrous on and off at programmed RPM's - I don't see why anything that uses RPM values can't be leveraged to do the same on a Duramax ECU ;)
Thanks everyone. :thumb:
I definitely agree there's no reason/advantage to spin it that high with stock components, but I was curious as to how high you could safely go, as well as what the weak points are once you start to exceed 3400 RPM and higher.
i.e. at what RPM does a stock...
