McCoy's Performance Posted July 6, 2007 Report Share Posted July 6, 2007 (edited) I gotta admit, 131 out of a non-ported min-twister 10 mil is impressive.... Normally, 120ish from a 10 mil cub on alky. I'm thinking I might send my cylinder to Jeff after this season is over to see how much he can tweak out of it. It's always been my belief you're not gonna coax more than 5 to 7 HP out of a cub, (After a clean up port) but...I'd love to be proved wrong.... The Mini-Twisters are cool for the fact not everybody and their brother is running it... Consider that the "Mini Twister" is far from "mini". lol They have the displacement of of the larger CP cylinders. We have seen the Twister shop bike with the 14MM " Mini, and it was very comparable to an average small bore 7mm cub. We had given them the benefit of the doubt since they were new then, but now they are far from new, and they just aren't doing what everyone had hoped. Some had thought that going back to yesterday's technology was better. Instead of Nikosil bore, the Mini is sleeved. The thought was that the time/$ of getting a sleeved cylinder bored was a better choice than Nikosil. But several problems seem to have not been considered. For example, it is easier to damaged the bore on a sleeve than the Nikosil. Also, many bore/stroke combos have very limited oversize piston availability, so re-sleeving is often required. And that is more costly than re-Nik'ing. Also the bore life is less on a sleeve than a Nikosil bore, so you have to do something sooner when all goes well. Cp Industries components have been good to us (ya, all the "cats"). And that is what we are building. I think the Twister folks are nice people, and understand why some people have chosen there products. But the new "little" DM cylinders are the next boom that is coming. We have done several 4mms and 10mm, and they are in a class of their own. We will have some Dyno Data from our 540cc 4mm and our 553cc 4mm very soon...
