tyrel Posted August 25, 2014 Author Report Share Posted August 25, 2014 Hey Stimbert, I will have to give you a call one of these days and talk about some ideas. Are you running stock bore /stroke? Quote Link to comment Share on other sites More sharing options...

Stimbert Posted August 25, 2014 Report Share Posted August 25, 2014 I've had a stock bore/stroke 350.. Big bike is a 950 scimitar Quote Link to comment Share on other sites More sharing options...
n2otoofast4u Posted August 25, 2014 Report Share Posted August 25, 2014 And as a side note. I'm still on gas... Haven't even put it on alcohol yet..I know you've changed the setup quite a bit, but when I used to mess with that thing with Cliff and Dan it was much happier on gas. It made its fastest passes on gas. Quote Link to comment Share on other sites More sharing options...

Stimbert Posted August 26, 2014 Report Share Posted August 26, 2014 Don't let this come off as cocky. BUT, even though dan doesn't get his hands on it much anymore he's still been kept in the bubble and I know he would agree with me on this. The problem with the big turbo motor and alcohol has recently been 100% figured out, just need a few t&t days to dial it in. Why not just do it you ask? I want to finish the year off having fun with it and getting it to run like a sob on gas and then switch to alcohol next year. Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted August 26, 2014 Report Share Posted August 26, 2014 Can you expunge a bit on the issues with alky? I'd imagine it has to do with getting the thing spooled with less heat movement? Quote Link to comment Share on other sites More sharing options...
Stimbert Posted August 26, 2014 Report Share Posted August 26, 2014 It took me 3 years and a lot of $ to figure out. I'd really like to keep that one to myself. Trust me, Your overthinking it though. Quote Link to comment Share on other sites More sharing options...

tyrel Posted September 2, 2014 Author Report Share Posted September 2, 2014 (edited) I took care of the crank seal issue (although on teardown i didnt see much movement) I welded aluminum retainers on both sides of the cases, the seals can no longer physically move. Not the prettiest but hey it should work just fine Bad news is this project is on hold until winter, upon re-assembly i must have missed somethnig that must have dropped into the intake.......found its way up the transfer port and took out the left cylinder, piston and head. So for now this build is out of dollars. When I get back to it I will have a few options......... stock bore / stroke / porting would leave it 350cc and eligible for a 350cc land speed record. also the cheapest option I could go with the 392 cub on the stock crank or do a 4mm cub I think I have the domes figured out so I will go with a TDR 1 piece girdle head The turbo should work well on all the set-ups. Any thoughts? it was hovering around 100 rwhp on 18psi boost Edited September 2, 2014 by tyrel Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted September 3, 2014 Report Share Posted September 3, 2014 There is a compromise on the exhaust port that needs to be thought of. The smaller less duration port would/should close sooner and trap more boost in theory, also might aid in off boost performance. But a large longer duration port allows it to just fucking charge once it gets in to boost. Typically for banshee cylinders, the inbetween would be like a "dune" type port. Similar to the serval...... N20? Quote Link to comment Share on other sites More sharing options...
Nieskes Posted September 3, 2014 Report Share Posted September 3, 2014 Wont the seal still be able to open up around the shaft? Quote Link to comment Share on other sites More sharing options...
m671054 Posted September 3, 2014 Report Share Posted September 3, 2014 Wouldn't there just be more pressure holding the lip to the shaft? That's what the sping does on lip seals. Quote Link to comment Share on other sites More sharing options...
