1.0 T4 Divided Ball Bearing 60 trim To4E, hard-lined cooling lines, Tial 44mm waste-gate rerouted, 3.5" vband downpipe, inconel turbine heat shield, and lim heat shield... Downpipe and manifold are out being coated too...

 

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)

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
