Last time I looked garrett had a se-r with gt28 on it.Think it made 280whp.Everyone who drove it just went on and on about how much quicker than 280hp it seemed.Disco potato if I remember right was the car.
why take the throttle off anyway?engine will have to work harder to compress full cylinders.
as for the propane injection,theres several turbo'd cars running 20+psi with secondary propane injection for it's anti-knock qualities.works well.
i know for a fact late 70's honda XL125's came with a center mounted slipin vane in the intake.was suppose to redirect flow towards the short turn.never noticed a difference with it in or not,but widening the short side would give them a noticeably stronger top end.so yea-there was an...
"The only thing that bothers me is that if I improve the flow would this influence the cooling efficiency of the intercooler?"
yes,but-the less pressure drop,the less energy required to overcome it.
"Ok, but still, what kind of overlap are we looking at at high rpm's 12000 or so?"
possibly none-overlap is a single item to think of in an engine package.efficent ports may need very little duration(overlap for that matter) to flow enough to support a given engine size well past...
