Question abour Wasp and Hornet motors

[Hurricane145]

Are the Wasp and Hornet motors for a particular group of racing such as group 10 or 12, or are they not for group racing?

[Buffalo Kid]

They are mostly for gtp type cars and indy cars. They are used in some classes that 12s are too powerful for and/or 16ds aren't enough...

When Mura developed the wasp motor, it was intended as an american made option to a 16D. As the hopup artists started to work on them, good magnets, advanced timing and balencing started to show the promise of a NICE motor. We have used wasps in 1/32 scale cars for 10 years and they now perform as good if not better than a GP-12 of 1992. Wind wise the motor is in the gp-11 catagory - something that I DONOT feel that the S-16C belongs in since it is more like a gp-20!

i have a kelly can superwasp set-up that dan p. made that is nigh on the match for a group 12. i put a hornet in it and it was more of a torque monster. haven't tried a sportsman in it but a contender is fun-very driveable.

Actually, the Mura Wasp WAS a gp.12 20 years ago.
Once upon a time, boys and girls, Gp 12 was defined as any not balenced Arm. The mechanical limits of the 70s(and economics), made that a "C" can with a short stack and a 65/30 wind with ceramic magnets.
Jerks like me were building 29 and 28 winds with balencing that was not quite appearent to the rules writers or tech inspectors. So, the rules were changed, the arm was allowed balence, and had to be tagged by the factory to prevent people like me from Cheating, err, not doing things that the rules writers did not think of.
So, Mura then looked at their standard C can cheapie and started selling them as "Wasps". Eventually Taggee them.
the Contender was what used to be the old Gp 15, before tagging, see above.

I am intrigued by Ramcatlarry's comment about the Super 16-C being more like a group 20 (it seems to me that my 12's are a tad faster than the Super 16-C and my 20's are much faster). Would anyone care to educate me further on the Super 16-C?

I figure that there is a reason that I might want to get one or more of the Super 16-C's. If so, I would rather find out or I might just go on thinking that I was happy.

Jim;

Larry thinks all motors should be classed by wire size. A group 20 is wound with 28 as is a S16C. With that thought though a S16D is a 28 wind should that be a group 20?

NOT

Actulally 20s are wound with 27 wire.
Quality counts, .007 lams make a faster arm than .014s, commutator quality and so on. Why the S16 just having a 28 wind does not make it faster than the Gp12 with a 29 wind.

Super 16c's have much longer stack. That impacts the length of wire used in the wind More wire = More resistance. Also the longer stack adds mass. More mass impacts acceleration / deceleration ( and handling too ).

Hope this helps

[Jim Person]

Can anyone provide a few examples of manufacturers that sell the Super 16-C?

[Buffalo Kid]

pro slot makes a good s16c, but other than that im not sure.

[Tim Holloway]

Jim:

ProSlot and RJR make this arm. The ProSlot arms seem to be consistently faster but I do have one very fast RJR.
