AarhusTr6 Posted January 5, 2019 Report Share Posted January 5, 2019 Hi Local ex Triumph shop closing up and offered for 200 quid a pair of rebuilt SU carbs and he said, from his experience it can give me a bit more power on the pedal over my Stromburgs. May I ask what the community think of this deal? Thanks, Rich Quote Link to post Share on other sites
harlequin Posted January 5, 2019 Report Share Posted January 5, 2019 Rich It made no difference to my car, mind if your Strombergs are worn rebuilt SUs would improve things providing the rebuild was up to scratch, and the correct needles are fitted. I also had a bit of trouble getting fuel levels right as the front carb has the float chamber a bit up from the jet and the rear is slightly down whereas Strombergs are concentric George Quote Link to post Share on other sites
AarhusTr6 Posted January 5, 2019 Author Report Share Posted January 5, 2019 Hi George I had a service kit applied to my Stromburgs but am unsure as to how well they were re-built. Rich Quote Link to post Share on other sites
Nigel Triumph Posted January 5, 2019 Report Share Posted January 5, 2019 The main advantage of SU carbs over Strombergs is the greater range of needles, effectively giving wider choice of fuel maps. If your engine is standard, Strombergs will be just as good as SUs. If the engine is modified, you may find fine tuning to get the optimum fuel mixture across all operating conditions is easier with SUs, because of the range of needles.

AndyR100 Posted January 6, 2019 Report Share Posted January 6, 2019 I’v used HIF6’s on a couple of cars always found the very reliable, just double-check the depth you have available; the internal floats mean the overall measurements are a little different to the older designs. .....

AarhusTr6 Posted January 6, 2019 Author Report Share Posted January 6, 2019 Hi there If the car was showing issues I also would buy them - but I think I focus shall focus on some other jobs I have planned. The the only 'issue' is I find the car just a bit gutless and missing a bit of oomph. Rich Quote Link to post Share on other sites
harlequin Posted January 6, 2019 Report Share Posted January 6, 2019 Rich Check the thickness of your cylinder head as US spec cars had a fairly low compression ratio, its a simple job to have the head skimmed to give say 9:1 which will give a boost to performance. I have the measurements for the head thicknesses somewhere and will dig them out George Quote Link to post Share on other sites
