Surveying a spare block for forced induction prototype. This is same basic block but the putt bomb 150/175hp version. The block is the same casting but sleeves are different, lower/smaller exhaust ports. I'm thinking this might be better for turbo use as will get a bit more power stroke and the boost will make up for it....Likely will just blow more unburnt fuel straight out the exhaust? But I guess a suitably sized turbine at the end of expansion chamber will increase back pressure as boost pressure rises?
Hi Jeff. With the testing that you have done so far how does it compare to a Yamaha 3cyl 1200cc 2 stroke?Paul.
In the second photo, are you about to straighten it by driving the forklift over it?
