RE: Tuning my Rs4-3
the 2 strokes in snowmobiles and other recreational vehicles of that nature have reeds which are a type of valve so to speak.
actually making the turbocharging effect more productive.
i don't disagree with the fact that supercharging these model nitro engines is not worth what they charge for them but do beleive that with a different pipe that builds more back pressure, it could be more productive.
i've actually had a supercharger at one point and found the power gains to be quite small for the cost.
and very fuel consuming to boot.
