Redline Racing Posted August 5, 2015 Report Share Posted August 5, 2015 I did quite a few 120 rod cubs and 125 rod DM's back in the day. IMO it was a waste more expensive and weaker cranks, thinner cases. With a twister crank it's just a bigger rod pin home on same wheel diam so it has less metal around OD of crank and pin area. CW 's won't go that thin on OD/ pin area so they use snap pins (step pins) to do the job. I've used Louie's with no issues on crank wheels but I've broke few step pins. Due to bigger bottom rod OD you must trench cases thinner to get all to clear and rod has to be trimmed. So now we have a more expensive rod, thinner cases and depending how thin rod is trimmed it can be weaker. All this for what I saw was little to no gain. Only plus I ever liked was the flat top KTM pistons you can run with 18 mm pins. I liked those pistons. Quote Link to comment Share on other sites More sharing options...
registered user Posted August 5, 2015 Report Share Posted August 5, 2015 today i called tdr to find out if their +7 cranks use the same diameter webs as the +4, which might also be the same diam web as a stocker. lady told me yes, but then again she might be clueless as she didnt seem very confident in heranswer. so ill likely pass on the tdr +7 crank, especially if its based on the stocker web diam. funny you should mention stepped pin. anybody thats been around the game for a while knows a step pin is a terrible idea and has risk of failure. tricked if you were planing a steped pin you may want to reconsider. if you one of the lucky few it wont shear in half but if it does youll probly have a big mess to clean up Quote Link to comment Share on other sites More sharing options...

registered user Posted August 5, 2015 Report Share Posted August 5, 2015 Plenty of engines run the gap through the boost port. Nothing secret about it. Its a better way to do it imo Quote Link to comment Share on other sites More sharing options...

Also, Lou makes the web the absolute largest webs you can fit in the case. The last one I saw from his shop was older, but it was a 7mm and the web was larger then stock. Not a ton, but enough to help the issue at hand. Quote Link to comment Share on other sites More sharing options...
registered user Posted August 5, 2015 Report Share Posted August 5, 2015 im sure that twister is made well. larger diam webs and plenty of material above the pin. for some reason i thought you would try and use stock case but that was a good choice with the matoons Quote Link to comment Share on other sites More sharing options...
