Dyno with ZC31S intake manifold
Clutch slip badly again this time
Hence define the unstable curve
Only managed 0.8b result instead of regular boost 1.2b
Rev limiter increased to 7800rpm as optimum peak come later
After some maths
The diff between both intake manifold is about 20whp on a turbo swift assuming both running on the same 0.8b boost
ZC21S Intake Manifold @ 0.9b = 190whp
ZC31S Intake Manifold @ 0.8b = 202whp
ZC21S Intake Manifold @ 0.9b = 190whp
ZC31S Intake Manifold @ 0.8b = 198whp
