Hello all. I talked to the guys who sell the Stc just a while ago. They claimed that they could get the C85 up to 105 hp on the bench. For their stc , to compensate the extra power, they had to specify a new timing for the C85 with the O-200 crank. Now, they said, if you "forget" to retard that timing... However, every engine will be different and not all would go that high in rpm and therefor power output, depends on the load also. And I forgot to ask what the carburetor was like when they tested it. However , it seems that with that stc one could get quiet some extra hump. What I don't believe is that you would not need more gas. Gas consumption and power output are somehow related. More power ---> more gas.

So, assuming it's legal, I guess it can't be 105 hp... > > Catch 22 > > John > ========================================================================== ==== > To leave this forum go to: http://ercoupers.com/lists.htm ========================================================================== ==== To leave this forum go to: http://ercoupers.com/lists.htm
