Just been on A.F. Rayspeeds site, no Dyno charts on there, only for the RB225. It must have been run on a Dyno at some point, so where are the print out's

Still want one

Have all 150 casings got as much meat around the transfers as the Indian GP150 has?
I do really like the look of this kit & have a S3 LI150 motor knocking around.

They're made using the same as the 200cc casing but with a 150cc casing mouth.

I know that the garph, which is taken from the Af website, is not very technical, but it looks to me that the RB20 has more peak power that the RB22.

.
I too have thought about the small block, a Gp150 one went for abot £30.00 on ebay yesterday

what sort of costings apply to the bits you have gathered together, looks very interesting
