megawatt Posted September 29, 2018 Posted September 29, 2018 What a fantastic day with Richard Board on the Dynabike dyno at Moto Works, Sittingbourne. Previous highest rwbhp was 113 with 36mm EFE carbs and pod filters. I had convinced myself that previous popping and flames out of the V_H were caused by dodgy wiring and ignition. Think I sorted that, so I begged Richard to lend me his RS 36 flatslides and pod filters. Different bike. Still, er, interesting at low revs, but above 5000 it was fuelling perfectly. Best run was 118rwbhp, the best ever. Then I thought I'd try a bit more ignition advance with the Shell V power. Best run 123.5 rwbhp. There's more to come from this 1170 motor. Quote
megawatt Posted September 29, 2018 Author Posted September 29, 2018 Not really interested in torque on a dragbike, but I'll dig em out. Quote
megawatt Posted September 29, 2018 Author Posted September 29, 2018 Max torque at 115 and 118rwbhp was88 and 82. Max torque at 120 and 122 was 87 and 86. Quote
fastbob Posted September 30, 2018 Posted September 30, 2018 I've had plenty of opportunities to put both of my GSXR 1100s on a free Dyno but I've always chickened out. I just don't think I could bear to watch or listen. I nearly got round to it but a V-Max spat all it's oil all over the dyno before my go . Quote
megawatt Posted September 30, 2018 Author Posted September 30, 2018 I've done many more Dyno runs at 10,000rom than strip runs. It will break a badly built engine, not a good one. Quote
Mickly Posted September 30, 2018 Posted September 30, 2018 I put my old Speedtriple on a portable dyno at a show.It’d got a 3:1 Zard freer flowing pipe and suitable tune.The power wasn’t up by much ( can’t remember the exact figure ) but the guy running it commented on how smooth the curve was without and dips or spikes, just a nice upwards curve with a short but gentle drop off just before the rev limiter kicked in, Reinforcing what I had felt on the road.However having some mechanical sympathy, hearing it revving it’s tits off in a metal box had me wincing a bit !!

Tango Posted September 30, 2018 Posted September 30, 2018 That's pretty respectable bhp and torque, Alan.......how much more do you reckon you'll get out of it? Quote
Mr Fro Posted September 30, 2018 Posted September 30, 2018 That's pretty respectable bhp and torque, Alan.......how much more do you reckon you'll get out of it? Loads more if he fits a supercharger. Quote
megawatt Posted September 30, 2018 Author Posted September 30, 2018 I ran 11.6 at Brighton and my last run felt quicker, but the timings were suspect. I have yet to fit two step and air shifter . I havent dialled the cams in or lowered the front end. I reckon there's a 10.9 in it and maybe 130 rwbhp. Not bad for a 37 year old air cooled heavy lump and a nearly 60 year old rider. Quote
