RS2 EX Manifold

[DJones]

Does anyone know what the maximum power limit is for an RS2 ex manifold i.e. at what power level does it become restrictive.

Cheers guys.

Most 20VT tuners claim 450hp figures but in real life I've seen 550hp with the rs2 ex mani. Perhaps it explains the fact that last 10 years everything past 450hp required K27 hotside flange as the K26#8 was the last hotside capable of max 450hp ...times changes and there is Garret K24/26 flanged applications going past 450hp limit....

400-450 past that and you've pased maximum efficiency, ask MRC

Thanks fella's i thought about 440, sounds like i am no being to optimistic for the old girl, in fact it sounds like it will only be the manifold that holds it back now, but 440ish will be enough for me.

Cheers
