I have been searching on the net for days, weeks even and have not come up with a satisfying answer.

I have turbo'd my 200cc single cylinder bike with the RHB32. I need to rev it up quite high just to get a decent amount of boost. I want to know if i switch to RHB31, will it help me boost sooner?

Basically i'm asking will RHB31 spool up sooner than RHB32? Maps would be great but a simple, convincing answer from someone who has actually compared both turbo would suffice.
