RE: Hilltop - 5

well?

C'mon, we all want to know how much better your bikes run now they've been 'Hilltopped'.

So first off nice to put faces to names , Geoff and the team very friendly and it’s a well sit up place . It would be too easy to fall into The emperors new clothes scenario and also focus on the final numbers bhp is rear wheel not crank derived and in the end it’s the real world riding experience/running that matters most .So that said ,figures were first run 102.51 bhp 72.78ft/lb torque after remap 112.7bhp 87.21ft/lb torque. On the way home the long way round, noticibly smoother when bimbling in lower gears through traffic not as snatchy mpg normally averages 57mpg today when I got back average was 61mpg. Also first run showed it was running very lean so fuelling now sorted so all in all a worthwhile exercise, not to sure what figures the other got and what they thought.

Like Mark I enjoyed the experience and meeting other members, anywhere that offers me tea gets a vote. My bike has 11% more power 100 to 111 hp, 15% more torque 75 to 85, is smoother and makes a fruitier noise from the Beowulf end can when closing the throttle. It picked up noticeably better during a bit of car bothering on the A14 going back home, 70 to ahem when I looked down was a surprise. My first thought was that it was worth it just for the noise so I'm happy. I may have to get my car done, that's got a 3.0 V6 diesel and apparently it can be mapped to give 600nm of torque.

Very interesting day, nice to meet the other guys.

Whilst the chart shows the numbers, what it can't convey is the real life change that the mid-range torque increase brings on the road. it makes nearly 15 ftlbs more torque at 4500 that's a quarter more and I've found a significant reduction in vibration when cruising in the 4 to 5,000rpm band too.

Whilst the max power increase was only 8bhp look at the curve of the before run (lighter blue line) it leaps 10bhp in just 600 revs around the 8000rpm region, whereas the after run (red line) the peak power is down nearer 7000rpm with a much broader spread, but to be honest it is all about that 3 to 6,000rpm mid-range for me. I got a feeling I'm going to be replacing rear tyres more often - but I'll enjoy the reason why :-)

And for Bravo, the excuses - mine was the only one with a completely standard exhaust system (headers and can). And on the very first run the dyno showed a very disappointing high 80's (bhp), apparently sitting on the M25 & M1 at 50mph on the way there (average speed cameras) for nearly 90 miles hadn't done the catalytic converter much good. It was taken to the red line and back to the mid-range 3 times which burnt of some of the crude and then it produced the 96bhp of the before run, with the comment that "... it is probably still a little silted up, take it for a Birmingham tune on the way home" (low gear high revs).

That graph is impressive, next time I visit the UK, I will definitely stop by at Hilltop (with an appointment of course).

Ok, must admit to some envy, both for being fit enough to ride (my backs in recovery thankfully) and for the tuneup you have had.
I guess you can never have too much mid-range power, that’s a real world useable benefit.
Thanks to all for sharing

Hi all,
Apologies for the delay in posting my comments it was a busy weekend of enjoying the smoother, gruntier stealthy (fast) black edition, and a 6 hour install yesterday.

OK for first of all, Geoff and the team are great. Friendly, lots of communication, banter and tea so a most reassuring environment.
As I had bolted headers and a can on my RS I declined the pre-map dyno run as I was convinced it would be running very lean, Geoff agreed with this so uploaded the software and then dyno'd it at 116bhp with 88ft/lb of torque.
On the road it's a lot, lot smoother, but the fun that used to start at 6K now starts at 4K I wouldn't claim it's turned it into a power house of a lump but the improvements in running and midrange flexibility and drive are more than worth it.
Gave the old girl a proper spanking down the B660 on the way home from Oxford

As a side note, BikePirates ECU was mapped at the same time as mine and Geoff will ship it with an appropriate invoice this week.

It's good but it's not right.
