dual mvr or dual mvs for gt4088r?
 

I am near the end of my build and im looking for an opinion on what gates to use with a gt4088r I will be running 2 gates and dump tubes


Compressor:
-Housing A/R: .72
-4" inlet

Turbine:
-Housing A/R: .95
-T4 w/ 3" v-band
Divided

Dual MVS will be plenty if plumbed correctly. They have been proven to hold as low as 6psi on our turbo manifolds( even plumbed back into the downpipe).

The MV-S isn't a bad WG initially they had failures with them in motorsports environments and then made them water cooled. If reliability on the track is of concern either water cool them or step up to the MV-R as well. You can see dual 38's have almost as much area as a 60mm gate.

Difference in WG area is as follows.

38mm WG 1134mm dual 2268mm

44mm WG 1520mm dual 3040mm

46mm WG 1661mm dual 3323mm

50mm WG 1963mm dual 3926mm

60mm WG 2827mm dual 5654mm

66mm WG 3421mm

Hope that helps.

thank you
