Hilltop

[papasquelch]

Currently there is an interesting discussion here https://www.street-triple.co.uk/index.php/topic,31994.20.html where someone has had a Triumph 765 R done at Hilltop, but is perplexed that although it’s got some more umph at higher revs, at lower revs it now runs badly. This is a classic case of the typical results when you simply add 5 degrees advance and/or 8% fuel across the rev range / throttle positions for example. Unfortunately those discussing the issue on that forum are erroneously assuming that the bike’s fuel and ignition tables have been edited using a dyno (and that the lower rev range can be adjusted and corrected). Note they’re also questioning the low, erratic power shown on Hilltop’s “before” dyno run print outs!

Well I have just had my bike done at Hilltop.

I know quite a lot about engine tuning including cam profiling, exhaust tuning, compression, valve sizes etc.

Had a good discussing with the guys at Hilltop and must say - he knows what he is talking about. We even talked about port placing on two stroke engines to influence at what rpm you can get max power etc.

All I will say is the bike runs much better in all rev ranges and in all gears.

I have put a full Akra system on the bike and it was evident of poor fuelling prior to the visit

Don't you dare ruin this thread with knowledge and hard facts !!

I see that he’s now telling Triumph owners that ‘Hilltopped’ bikes will only show a power increase on his own dyno; other dynos won’t show any power increase. Oh please!!

“I see someone in the USA claims he was told........... “

You seem rather ready to accept what someone ‘understands’ to have been said?

Send three-and-four pence ..... we’re going to a dance.

Errrrr what hard facts?

Strange, how my T12, which has a Hurricane engine, showed an improvement.

Other dyno's could show a power drop, you seem to be one of those people who believe that all bikes make their stated horsepower and; the end can gives + 5bhp; headers are +8bhp, K&N +3bhp so my bike makes X + 16bhp therefore it is better than yours.

Shite.

It is about flexibility, drive and usability. My rr has 206bhp at the wheel, I rode bikes 18 years ago tuned to buggery to get close to the same, and they were pretty much unrideable for 90% of the time.

If, you prefer to spend your money elsewhere and on different things, good luck.

But please, you're coming over as a troll, narrow minded, bigoted, and with an agenda. Is that how you wish to be seen ?

the fact I had a good in depth conversation with them.

As you are not that far away from Nuneaton why don't you just tag on the end of one of the arranged group buys.

You could hang around , listen to the conversations and maybe even ask some relevant questions.

A good in-depth conversation is not hard facts, sorry to be pedantic

True, but an informed discussion can lead you to find out facts that perhaps you were unaware of or that they were pertinent and relevant.

ok backup up by the results of a tune - on hard paper

The end of all those Hillltop threads would be if you took 2 GS-LC from the same year,one with the latest BMW sw-update and one after it got blessed from Hilltop at the same day to the same dyno running the same tires because even that can make a difference in readings to see what really happens where the rubber meets the road !

Sort of; sadly some bikes are "better" run in than other's, or tolerances more inline with design spec.

A couple of bhp down is all that is need by the naysayers to confirm their views, and no emperical evidence will sway them.

It's whether it is smoother, feels better and more flexible than before is ultimately what is wanted.

I do wish we'd remember this is an air cooled twin with around 125ish bhp not an H2R.

Air cooled...?

Yes, the heat transference is via water or oil coolers (radiators) and hence by air.

My old mecheng lecturer was very particular and precise.

Mmmmm...... I think the accepted rule is:

When talking about an engine in isolation - the BMW LC engine is “Watercooled” by way of it having water jackets.

When talking about an engine “installation” - the ‘ultimate’ method of heat disposal is the accepted naming rule. This would apply to a package generator where there is a radiator and a powered fan, for example.

The BMW engine is not classed as an “installation”.

Wouldn't that apply to pretty much every car/bike/truck engine?

Sort of, maybe.

From memory, the late great John Robinson explained how Japanese manufacturers got their final bhp figures, with step by step removal of frictional parts.

Imagine an average gs makes 125 -10% friction/transmission losses so 110 at the back wheel.

A poor one could make maybe 104 and a good one 115 on a dyno, (all things being equal) getting a 104hp gs up to 110hp could be fairly simple, possibly even more; but it is unlikely that you'll get much extra out of the 115hp gs. Law of diminishing returns, or shitloads of more money.

It's about how it improves driveability, not a magical number. I did that 30 years ago with Cosworth's, I've grown up now !
