A while back there was talk about converting a Super to the 52mm magnum cylinder and piston.
Do the mufflers and intakes match???
Has anybody done one yet?
I've done a couple, I'm sure you'll have no problem with it.
A super base gasket is handy to scribe out the location of the screw positions on the mag cylinder, the resulting slots make an angle and you grind more in one direction (front to back) than the other (side to side). You'll need a dremel with some carbide bits to grind the outside of the barrel to allow the cyl screw heads to seat and/or thread into the case. Most of the access holes also have to be opened up so you can get the T-27 to the bolt heads. A 7/32 chain file does that fine, I chucked one in a drill.
The intake bolts right up as does muffler. The mag exhaust port is a bit wider and I matched the super muffler to it.
I opened up the existing slots on a dual port muffler and also opened up the baffle inside.
I used an OEM P/C , a Bing carb with the above muffler and it's stronger than my 038 mag (maybe not a great comparison as this one has lots of hours on it).
It runs fine with the original Tillston carb and it has the same venturi size as the Bing; I used the Bing as I heard good things about them here.
If you come up with anything interesting to do besides the basic conversion let me know. I've got another 038S ready (another bad gas freebie) for the same type of conversion.
This might also be doable with an 038 AV too, but the service manual mentions having to grind the case a bit to get a super cyl to fit an AV.
