glang Posted May 2, 2018 Share Posted May 2, 2018 Theres a nice set of three SUs and Triumph manifold going on ebay. Dont know what size they are and of course theyre meant for a 2.5 but Ive always thought they are the way to go rather than Webers. Anybody know what its like to run with that set up?

Clive Posted May 2, 2018 Share Posted May 2, 2018 They are not easy to get right. It is to do with the firing order, and the middle carb needing to be set differently. Bruce afew years ago did it, it was loads of work and time on a rolling road, with the manifolds needing machining to get the flows to match. In all honesty, looks nice, but twin SU's likely to produce as much power and be much easier to live with. Sorry to be brutal.... Quote Link to comment Share on other sites More sharing options...
Gt6s Posted May 2, 2018 Share Posted May 2, 2018 As Clive says. The Triumph six is technically two three cylinder engines and needs to be treated as such. Webers are a different story technically a carb barrel per cylinder as is PI. Three single barrel carbs is not the way to go. Not on a Triumph six anyway.

glang Posted May 2, 2018 Author Share Posted May 2, 2018 Thanks for that, makes me feel a lot better - think I'll carry on with my pair of 1.5" strombies! Quote Link to comment Share on other sites More sharing options...
Gt6s Posted May 3, 2018 Share Posted May 3, 2018 Put on a pair of HS6's. I really fancy putting a pair of HS8's on one of my 2500 engines. That is if my mate can dig them out for me as he promised. Laurence Quote Link to comment Share on other sites More sharing options...
