Exhaust manifold for fp red

[clipto]

So I have been trying to figure out what to do, now the fp red turbo has 8cm housing but the fp manifold is 7cm. So would the fp manifold still be suffice for the fp red? Or should I do something to match the 8cm of the fp red turbo?

The "cm" is not a measurement of the manifold hole. It's from the "scroll" of the turbine housing. Buy the FP race manifold, best one to use for sure.

Oh ok I was confused for a sec I was just making sure the fp manifold mated to the fp red hotside, thx.

The outlet of a FP manifold should be 60mm to mate to a ported 7cm2 turbine housing.

The 7cm2 or 8cm2 is a volumetric measurement similar to Garrett's a/r spec and has no direct relation to the physical size of the turbine housing inlet.

The unit "cm^2" is a cross-sectional measurement, nozzle area. Volume requires a third dimension.

Ok I just wanna make sure all that will flow enough for 500whp on e85 fwd auto. Otherwise it's an hx40.
