yamahaxcracer Posted February 16, 2012 Report Share Posted February 16, 2012 (edited) Hey guys. I have looked through this huge forum and i cant seem to find anything about a 421 twister. I am curious as to what hp and torque a 421 drag ported twister can make on pump gas or even race gas,, assuming I would have Shearer Inframe small bores, VF3 reeds, Dunable over ride, 38mm Keihin carbs, direct drive lock out, billet 1 piece crossover, and either Noss or Prodesign Coolhead and not sure of dome size.. and also I will have drag ported cylinders, and probably +4 swinger, i will mostly dune and 15% hill shoot sand.. i weigh 153lbs and I am not sure who will port them yet, but i think i know the top 5 to 6 guys who can port these... I would just like some input or if you think the setup I am shooting for should be changed please let me know,,, i am going to buy a cheap banshee and put the above listed parts into it,, I saved up 6,000 so i think i can buy whats needed to make this happen.. Any comparison between 421 twister and 421 cub ? do they feel the same? power delivery.. I do not want a Cub because it seems everyone and their cousin has one.. Here some pics of wife and girls in our group of riding in Oregon 2011 Thanks in advance guys..

camatv Posted February 16, 2012 Report Share Posted February 16, 2012 umm have you ever thought about maybe trying to call twister and see what they say????? if you can try to do a PV cylinder. even if they try and talk you out of it. then also pm bigred as well.

jrmarquez.702 Posted February 16, 2012 Report Share Posted February 16, 2012 I've got a 4mil twister(466cc) and I feel like the power is everywhere unlike my cub that is harder to get into the powerband. Plus, I think the twister just looks cool. I only saw 1 other twister at dumont on thanksgiving....ps. Bigred350x is the man when it comes to twisters, even thou he doesn't own one.... Lol Quote Link to comment Share on other sites More sharing options...

lowbuckracing Posted February 17, 2012 Report Share Posted February 17, 2012 Build a wampus,80 hp out of the box,91 oct pump gas and u can trail ride or drag and still rips. Quote Link to comment Share on other sites More sharing options...
J-Madd Posted February 17, 2012 Report Share Posted February 17, 2012 The Wampus would be a cool motor. Looks like bone stock cylinders. If you do want to go with the Twister, you better start today trying to get it built. It takes forever to get stuff from Louie. I'm waiting on gaskets for my 16 mil Twister (669 cc) right now. I also have a 24 mil Twister (844cc Sniper). Only a handful of those out there i think. Quote Link to comment Share on other sites More sharing options...
