Triumph TR6 - Triple Webers?
|I am in the process of a total engine rebuild for a 1972 TR6. I would like to do a reasonable performance boost, and would like opinons/comments/experience on using the triple weber setup. Thanks.|
|When I rebuilt my 1974 TR6 engine I added a mild cam, took 50,000inch off the cylinder head,put on headers(they were dificcult to put on), electonic ignition and added triple webers and the car works very well(an electric fuel pump is not necessary). I have good gas milage when cruising and more toque than I know what to do with!! I must add that getting a mechanic to dial all this in is a must. Just adding the carbs and hoping they work is very chancy. Please let me know how you get on.|
|exhaustwith the point that just putting on Webers is not the answer. Webers are just bigger buckets for shifting petrol. If the engine can't take it in, you can't benefit from bigger buckets.|
1/ Electronic ignition. Even a new Lucas dizzie will falter a bit a high revs. ?
|Thanks for the comments. It only makes sense that a whole lot more carburetion needs an engine properly prepared to deal with it. I am currently researching an appropriate cam. Cambridge has a "fast road" cam that they have recommended. Anyone experienced with these? In my part of the world the highest octane rating commonly available is 91. I have been told that compression ratio of 9.5:1 is barely doable with this gas - so I am thinking about milling to get around 9.25:1 and getting the porting work done.|
|Thanks for the feed back, Rick.|
I'm not familar with the Cambridge cams, but a 'fast road' usually implies higher lift and a modestly increased 'duration'. The latter will tend towards getting more power at higher revs, which you may, or may not want. Higher lift may benefit from 'roller rockers', another significant expence (?£400), but may be worth it in terms of reliability and reduced wear.
