Those awesome charts are very informative. Thanks for sharing. I agree that the SAE factoring is more realistic than the STD. Moreover, the baffle power robbing impact should come as no surprise but very enlightening nevertheless. You have now rekindled my interest in installing a left-over Rapidbike unit onto my stock 1260. This would tell us how much improvement comes from only the map change thus the remainder would be from the plumbing. One this note BTW, I really like your editing skills. Can you do anything with this chart (RPM and SAE) and overlay it onto your other 1200 chart? It's my mates stock 2017 1200DVT exhaust but with the addition of a Rapidbike unit. It would also be handy to consolidate all 1260 Dyno charts here: https://www.ducatiforum.co.uk/threads/dyno-sheet-1260.63926/
Mid range often missed by people when looking at benefits. Its all big top end numbers people look for....but this is why the bike feels more urgent after even a slip on and set up
Not sure I am quite understanding the last chart but I would imagine it is very unlikely indeed that anyone will notice 5bhp + or -.
Although this is a superimposition, your chart is revealing. @Duncan* and feel free to step-in anytime to discuss your methodology. It seems the Termi with Upmap adds power over stock, (baffled and un-baffled) up the mid-range. The Termi, baffled and un-baffled detracts power at the lower end (i.e below 5000), and at the top-end (above 8500) when baffled. My Dyno chart (Stock 2018 Multistrada 1260 PP)
Mid range is where it's at. Looking at those figures I'm pleased I went Termignoni Uscite baffle out + UpMap on my V4S. It releases a couple more ponies than the Akra's by all accounts, but as mentioned, probably not noticeable.
I was going to get mine remapped but after speaking to the mapper, they said the gains would have been negligible so I saved the £300. If there had been an improvement in torque, I'd have done it.
I did not provide torque figures. Consequently you may want to use this Cycle World torque curve for a stock 1260 for consistency. In fact it may be clearer to use both the HP and the Torque from this chart which has the RPM's on the X axis. Moreover, those torque curves cannot possibly be taken from a dyno at the rear wheel as they are way too high. Do you have your actual "Full Termi" dyno sheet for torque? https://www.convertworld.com/en/torque/newton-metre.html
Hi Duncan, there's no way that a stock 1260 can generate (on a rear wheel dyno) 130 Nm @ 7000 rpm as shown on your chart. That's about 96 ft-lbs. I would use the torque curve from Cycle World above (even when converted to Nm) which is congruent to this one from ridermagazine.com below: As you can see, it's nearly identical to the Cycle World torque curve. Peak torque occurs at 7800 rpm on both charts.
Tbf Ducati claim 95lbft or so Cycleworld are Us I think and Us dyno always seem to show less than UK. I think there may be a calculation difference
In its simplest form, What's important is that Ducati measure both HP and Torque before the gearbox drag.
You might want to confirm the UK numbers are HP and not PS...0.98 difference That said ALL dynos are different...unless the runs are the same day by the same tech there will be variances...+\- 3-8 HP not unexpected on a 130-140 bike. A crafty tech (to get business) can add the same value if he so wishes.
So is there anyone that has bought the full Termi that regrets their purchase (too loud, low rpm power loss, price, etc)?
