If you do decide to run a muffler, it will likely last a long time as the turbo will take most of the energy out of the exhaust. Thanks for posting the make/model for your turbo. I'll be interested to learn how well it works. Mark S.

Greg,
 
Running a turbo will probably negate the need for a muffler.  If you do decide to run a muffler, it will likely last a long time as the turbo will take most of the energy out of the exhaust.  Thanks for posting the make/model for your turbo.  I'll be interested to learn how well it works.

Thanks Bob. Mine is a Turrentine built engine with NA rotors in turbo housings (no splitters).

One question. Do you know if Paul ran housings with the splitters or without?

Mike Wills

Mike,

Paul used a Turbo engine without the turbo. So there were no  splitters. Doing so with splitters probably would help also. Just my  opinion tho!
