Well, it seems that progress continues on several fronts. I have a Street twin and it seems up until this week there has not been much work done on the Street twin performance outside a few well known racing shops with ties to Triumph.
TEC performance in the UK has apparently cracked the performance limit on the 900cc WCTs and has built a cam used only with a stock ECU, x pipe CAT delete and Vance and Hines Fuel map to produce 70 HP at the rear wheel. Amazing gains on what he describes is a moderate cam grind. By some luck I was able to secure a slot in the first limited production run hopefully to be ready by January or even sooner.
His reasoning is that the 900cc and 1200cc are not significantly different in potential power. So why the big HP difference? In his thinking, Triumph for marketing reasons, has seen fit to make the difference more profound by severely limiting the 900cc engines with a restrictive cam, one throttle body and smaller valves. plus a few other obvious things like sleeving the cylinders, tune etc. He reckons when he develops a cam eventually for the 1200cc engines the gains will not be that great, but around 15-18%
increase. Check out his you tube intro;
