MORE POWER!!!!!!!

[D6]

throw an exhaust at it, and make it breath better,itl liven it up a bit.mine was much better with a remus and controller fitted..mid range wise,,
theres a few ways of altering the fueling ratio etc, other than that it isnt gonna do much good unless your rich,
wanna go fast? buy something with more than 2 cylinders imo,
these twins are about mid range poke

Pah- ignore the above and have a go.

The OP's question is not HOW to do it. The how is relativly easy and shown in the HP2 Sport's engine package.

The bod's question is:

How much power is attainable from a reasonably standard 1200 gs engine.... Blah, blah...Without a turbo..... Blah, blah.......can you lot fix it for me to have an accurate ish guess at what it may handle before going south in probably quite a big sudden and dangerous way..

In short: How much power is possible from the 1200 engine? Before it goes BANG! That's what he wants to know. The current readily available measure is the HP2 Sport at 130 hp......

But, no doubt there's a UKGSer homegrown 1200 expert that'll tell us something astronomical as a mate of a mate of his told his mum in the pub of one that she had seen (or was it heard about) in a secret bunker....

There again, it's not difficult to guess that the endurance racing version may well have kicked out a few more ponies and lasted 24 hours non-stop into the bargain without going POP!... A search of the www may turn up the data, if the teams released it.

i recon around 20 horse without any big internal mods,reliably..
more a question of WHEN you want it to go pop really

 

[skywalker]

Final drive will need beef'in up to cope with the extra power otherwise it'll break. FFS what am I saying -they do that anyway !!!

 

[stanley]

Hhhmmm.... Yes...... hard to know how much it will take then.
HP2 + a bit??

Are the HP2 internals similar?

How about a "controlled" nitrous kit?
Keep the engine bog standard, but press the button and have as much extra power as it can handle. Pulsing solenoids to control how much nitrous and extra petrol you squirt in.
It's surprisingly kind to engines too... if you don't go mad

I put an old fashioned turbo on a Suzuki GSX. Didn't cost much- biggest expense was having custom stainless pipework made. Power was almost unlimited, but it was horrible to ride.

Got me thinking this now...... Reckon nitrous would be easy (ish). Wouldn't have to touch the standard electronics (maybe timing?), just get the fuelling right through control of secondary petrol pump or solenoid.

 

[D6]

dont think you would even need a petrol solenoid, most jap injected bikes can run a dry nitrous system now,
presuming the bmw electrics are as advanced as these , it makes for an easier fitment

 

[Wapping]

Hhhmmm.... Yes...... hard to know how much it will take then.

That hard bit is the very bit mark2jag wants to know

All this talk of pulsing solenoids is getting him no closer to finding out..... All you keep feeding him is the HOW....

 

[D6]

well if he knows HOW then perhaps he will try , and then KNOW?

 

[Wapping]

well if he knows HOW then perhaps he will try , and then KNOW?

Way too complicated and too fraught with turbos and the the big bang potential, he is so keen to avoid.

an accurate ish guess at what it may handle before going south in probably quite a big sudden and dangerous way..

Anyway, you've had your guess:

i recon around 20 horse without any big internal mods,reliably..

A figure spot-on the HP2 Sport number

Now, boys and girls, any advances on a guess at 130 hp (with torque figures, preferably)?

More Power

For my penny worth - have done all the usual mods to my 1200 gs , full system (BOS) K&N Filter PC111 , this was to my 2005 - the power gain was good , it read 101 bhp at the rear wheel .The main thing i noticed was that the bike felt ,how can i say , looser and free, a definate improvement from the standard.
As for big gains in power not sure , maybe porting and flowing the heads would release more horses without the relability factor being comprimised .
Bmw tuning firms do cams etc but not had much info about them.
My new 1200 Triple Black 2001 kicks out 102 bhp at the wheel same system but using a PCV - not much difference but the new twin cam engine does feel more powerful.

Sorry but that's way down on even the engine's known potential (and the colour scheme doesn't help)....

Have another go... A guess at what potential untamed and untapped beast lurks within the pots.

Bhp is normally quoted at the crank -not the rear wheel and the loss is around 10 to 11% so the bike is running around the right mark but with the exhaust etc makes a smooth difference ( the Triple has only done 2500 miles so still tight) The old 2005 i think was around 100 at the crank ( may be wrong so ) so 100 at the wheel was pretty dam good by my book.Plus every bike is different - remember the friday build theory

How wrong can one man be........that colour scheme is best by far

More POwer

Beamish - must agree with you some ........ must have a colour thing
Also led by brochure hype Love to see their dyno readouts , as some do make the effort to find out rather than read the boll--ks that the glossy paper spouts topping

 

[Boxerboy55]

. . . Years ago I read a magazine article where the writer that said that whenever he wanted a faster bike he considered how fast the racers of the day would be able to go on his current bike, and then applied a bit of concentration to closing the gap. Makes sense to me.....

I like that logic. Think I'll work on it next year
