Long runner intake manifolds usually make more lower RPM power. The advantage of the long runner turbo manifold is nice smooth bends. Bends are the enemy of a turbo manifold. Would you ever really see a big difference on a street car between short runner and long runner in terms of performance? I seriously doubt it...

I don't have a dyno sheet for this particular turbo, but it should be at 1 bar @ 26/2700rpms. Usually in positive pressure right off of idle at WOT.



Here is a bigger 61mm turbo( much laggier than a 57mm turbo(60 trim to4E)

Look at the torque curve, a LOT of power at low rpms.
