volvo63' Posted December 6, 2011 Report Share Posted December 6, 2011 Can someone please enlighten me on some of the specs of this small block twister I've been hearing about? Quote Link to comment Share on other sites More sharing options...
ban565 Posted December 6, 2011 Report Share Posted December 6, 2011 What specs are you looking to find out? It comes many different bore sizes. I have 10mm with a 75mm bore and the cylinders can be bored out. Quote Link to comment Share on other sites More sharing options...
ban565 Posted December 6, 2011 Report Share Posted December 6, 2011 Forgot to mention that the exhaust flanges can be changed between small flange and big flange pipes and the intakes you can stock reed cages or cr125 cages. Also go an look up twistercrankshaft.com Quote Link to comment Share on other sites More sharing options...
lowriderb Posted December 6, 2011 Report Share Posted December 6, 2011 (edited) i have the same size motor as ban565, they can be set up with a good bit of different variables, stroke/bore/intake size (bolt up flanges)/exhaust flanges(again bolt up flanges). mine made real good power on just motor. http://67.199.65.66/twistercrankshaft/store/store_view.cfm?store_area_id=22&STORE_DEPT_ID=286 Edited December 6, 2011 by lowriderb Quote Link to comment Share on other sites More sharing options...
BigRed350x Posted December 6, 2011 Report Share Posted December 6, 2011 It is a billet cylinder block made by Twister. Bore sizes range from 68 to 78mm. It uses an iron sleeve. They have tripple ports and boost ports. They come with what most would consider a dune port, and have plenty of material left to be hogged out and custom ported however you want. They have a much larger coolant capacity than competitors cylinders, and better coolant flow characteristics. They have changeable intake runners and exhaust flanges. You can run stock banshee reeds or YZ250 reeds, and small-bore or big-bore pipes. They are a great cylinder and I would recommend them to anyone. Here's a Twister Big-Block for comparison...

Pasi S. Posted December 6, 2011 Report Share Posted December 6, 2011 I have been thinking seriously getting Twister block after my stock cylinders retires. If I fak up a nicasil it will cost me a fortune to get them fixed. No one in Finland can´t do that. What kind of power the stock port Twister will make with pump gas (4mm, 68 bore)? What are the "Best bet" pipes for it? I don´t know why, but I can find much info about them. New bore and hone costs about 80 dollars (60€) here, and it´s local shop. We don´t have dunes here, so I don´t know how is the "dune port", so what are the numbers? Thanks. -Pasi S. Quote Link to comment Share on other sites More sharing options...

volvo63' Posted December 6, 2011 Author Report Share Posted December 6, 2011 So would you guys recommend a serval or 10 mil cub or this cylinder? Also what's the big difference between the interchangeable reed sizes. Quote Link to comment Share on other sites More sharing options...
alcoholbanshee Posted December 6, 2011 Report Share Posted December 6, 2011 It is either stock intakes of cr125.............it does not use yz250 as posted above.............. Quote Link to comment Share on other sites More sharing options...
lowriderb Posted December 7, 2011 Report Share Posted December 7, 2011 So would you guys recommend a serval or 10 mil cub or this cylinder? Also what's the big difference between the interchangeable reed sizes. the cub motors were designed to use the style parts that you already had, reeds, intakes, head.. the mini twisters are complete top ends similar to the cheetah's. the advantages of them are the intakes and exhaust flanges are interchangable so you can change things on the motor yourself as you want. the iron sleeves can be bored out or changed out to bigger sleeve sets, i have heard of them going as big as 78mm's with the mini's but they are advertised to go up to 75..

BigRed350x Posted December 7, 2011 Report Share Posted December 7, 2011 are those seadoo power valves on those cylinders? They are off of a skiddo summit 800. The valve itself had to be machine down to match the shape and profile of the exhaust port. Quote Link to comment Share on other sites More sharing options...
BigRed350x Posted December 7, 2011 Report Share Posted December 7, 2011 It is either stock intakes of cr125.............it does not use yz250 as posted above.............. Depends on which generation of the small-block you have. There have been 4 generations of the small-block since it was released. You CAN find them with YZ250 reed cage intakes. Either way you go, they are an awesome cylinder. Quote Link to comment Share on other sites More sharing options...

Also what's the big difference between the interchangeable reed sizes. If I had the choice between the two I would do a 10mil small-block twister.
