Decided to go with the Jaws Twins for the 860R. Hopefully have them in a couple weeks. Nice that they will build them to fit in the Rev chassis for the R motor. Greg at Jaws was great to work with.
The Crankshop Mondos just had to have too much work to get them fitted in the sled, & I didn't like the PTO pipe configuration, which was causing problems with fueling etc. I got by on the dyno running a balance tube between the pipes to average out but it wasn' right. Also I never did know for sure these were for the R motor and with the different port timing from the series 3, well I'm taking care of everything with this move.
I originally bought them used from a guy down south and I got them cheap enough that I could take the risk they would work out. Served the purpose for all the testing on the dyno and they showed me the motor wanted the extra flow, so it was time for some good pipes!!!!!
