yoeddynz Posted April 21 Author Share Posted April 21 I've got extra outputs on the megasquirt. I could set up a stepper motor to open them at set values. But realistically I'd probably just be opening them at certain times for lol effect. Like outside an oldfolks home at 3am or next to a community hall where there's a workshop for those who suffer from ptsd. Joke. I would not do that. 7 Quote Link to comment Share on other sites More sharing options...
SOHC Posted April 27 Share Posted April 27 I have tried sliding doors and butterfly valves in home made mufflers with much disappointment, you may get a slight change but the baffle chamber of the bit of the muffler that has been bypassed still will still do its job if any part of it is open to the exhaust flow.

yoeddynz Posted April 27 Author Share Posted April 27 Oh its totally an experiment and for sure there's a chance it might not make a huge difference. It's quite a big shortening of the route though so I feel ill see a fair bit more noise when they are open. I'm excited to find out. Quote Link to comment Share on other sites More sharing options...
SOHC Posted April 28 Share Posted April 28 Just have it as an empty chamber and it should sound like some kind of super car Quote Link to comment Share on other sites More sharing options...

Truenotch Posted April 30 Share Posted April 30 The muffler is looking good. You can buy muffler packing in sheets or as loose fluff. We used to sell a bunch of it at City Honda and it's more hardy than using wall fluff or other kinds of fibreglass insulation.

yoeddynz Posted May 1 Author Share Posted May 1 Cheers Chris. Interestingly the other chris @chris r recons he's got some for me too I'll be able to fill the whole cabin at this rate. It'll be one super quiet, slightly itchy ride. 2 2 Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted May 2 Author Share Posted May 2 Some automotive giant just has to go two better than me ... https://www.drive.com.au/news/new-eight-cylinder-engine-unveiled-by-gwm/?fbclid=IwZXh0bgNhZW0CMTEAAR1aiB3PXuiLRd9ukNk_ucsvESzdzwxU9-_stypa2F3u6aTlry_BaVBOc8A_aem_AcchXiUEBUlrG8C2lcTfmSXIf_SOxeiKhKhFSjGGpB7CQ0ORNZUjLV_zXG-FUCh7Tkzl9RHVbHNFSWTX_L7cJHTY 'It's understood GWM is looking to enter the motorcycle market, with the flat-eight a good indication the company will be targeting large touring bikes such as the Honda Goldwing and BMW K1600. However, some industry pundits have already begun speculating which classic cars would be best suited for the eight-cylinder motorcycle engine' 5 1 Quote Link to comment Share on other sites More sharing options...
Muncie Posted May 3 Share Posted May 3 There's no videos of that GWM engine running at least so your still 6 up on them. Just an Asian exec making finger guns at a car show. If you could make a parody that would be excellent and end it with a running engine in an imp. 1 1 3 Quote Link to comment Share on other sites More sharing options...
GregT Posted Friday at 08:00 Share Posted Friday at 08:00 The subject of goldwings came up on a motorcycle forum. I'm told that when the 1000 came out Honda UK sponsored one in a roadrace sidecar outfit. It got shelved as they couldn't solve oil surge problems - it kept doing crank bearings. Given your flat floor sump, i'd be tempted to look at some baffles to keep oil around the pickup. And a pressure gauge in easy view. If I've missed you doing a solution to this, carry on.

yoeddynz Posted yesterday at 02:00 Author Share Posted yesterday at 02:00 Yeah it's got baffles and a high oil line. The cylinder bores extend in quite a long way toward the centre line too so the oil can't 'ride up the walls'. I think it'll be OK but time will tell for many of the aspects within this build. Otherwise it becomes the world's longest coffee table build... Quote Link to comment Share on other sites More sharing options...

GregT Posted yesterday at 07:35 Share Posted yesterday at 07:35 There have been a number of V8's created from motorcycle fours for use in speedway etc. The top ends on that look like current best practise Suzuki/Kawasaki/BMW on a special crankcase. Wouldn't be too hard to do given the number of V8's that have been built. Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted 16 hours ago Author Share Posted 16 hours ago Radical cars make an especially nice V8 with busa heads. 1 Quote Link to comment Share on other sites More sharing options...
