Anyone got a Carl's 660 and running SLP twins? Preferably a ProX with twins, but even and Edge RMK with twins would be of interest. I'm curious on carb setup. I've got 2 660s, one in an edge rmk chassis with the single... Runs awesome. Recently acquired one in a 2003 ProX chassis running the ProX 600 slp twins. It runs well, but not so good on the bottomend.

Just curious if anyone has a setup that is working in that configuration.

Thanks,

Curious as to what can the Pro X has. Also what ECU the pro X is running.

Those flatland sled ecu's don't like 7k plus.

The SLP twins for the ProX chassis go into a coated canister.

The whole setup was actually an RMK transplant, with all the RMK electrics and everything.
