looks nice but what is the advantage of long runner high mount manifold ? iirc long runner gets better top end ?
|
i thought the longer runner made more torque?... or is that for the intake runners only?
|
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...

any ideas how low in the rpm range.. hard to swallow a single bein any good for autocross

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) https://www.nopistons.com/forums/top...4-gt3574-dyno/ Look at the torque curve, a LOT of power at low rpms. |

The owner told me they did a run at 16psi and got 405rwhp/365rwtq |
