New 1250 heads...

Fuck off, variocam plus and direct injection, dry sump, 7 scavenge pumps and a host of changes to reduce the friction and and improve oil flow with lower oil pressure. That is how Porsche got an extra 20hp from the 4.0l lump. Basically they developed and tested it in racing, read Porsche cup, so a totally new engine which in no way resembles or part resembles a BMW boxer let alone would share a similar maintenance regime or schedule. Porsche learned from the last GT3RS engine which caught fire and a few owners left without their GT3RS. Go find another forum to piss on you bloody troll.

And just for info, it is not economically good practise to have 2 cylinder heads, like v-twins and flat twins because the design add complexity and increases maintenance costs. But it is an European thing and when it is part of your identity as a brand you cannot dump the design easily. Once again, fuck off!
 
and I'll raise you this. Want to know what a Porsche engineered motorcycle engine looks like? Harley Davidson V-Rod. Now off you fuck.
 
The latest GT3RS...2018/4.0/520hp...actually 519hp/8100 rpm 475nm/6200rpm on sport-auto dyno 3996 cc which would translate to 1332 cc / 173 hp / 158nm if it was a boxer twin.

Interesting, but it seems your mathematical determination is wrong - can you show the workings in detail please?
 
Why don't you guys just fuck off and play with your boring mates who can't afford new LC's anyways in the Afreekatween,R1100S best BMW ever or yellow pumpkin forums instead of posting shit that has nothing to do with the topic !
Tannenbaum everyone can read wilkipedia but the engines you talk about were all exchanged for new ones,owners got money for the downtime and all they had was a few connecting rod bolts that had not been torqued right.
Nobody forces you here to post...especially since we all know that you don't like BMW LC boxers and think boring A-T and orange plastic is way superior to any GS-LC...
We got it and now just f@ck off and leave the adults alone...Go to your forums and have fun as I don't go there and piss all over your place...but I guess your mothers never gave you any love or taught you any manners...!
The Monty Python brigade...:D

First class rant:thumb
 
So if i buy the new R1250GS will it be fitted with a porsche engine:confused:
 
Seems like the cat's away.

Just when I was getting a grasp of valve timing, they make it variable.

This should be a technical section, is speculation allowed? Evangelism?

Have I fallen in to the trap?
 
deanOnO, it looks like the new 1250 boxer gets a cam system that uses two cam lobes on the intake side and not the alphatechnik VV-L system...Will be interesting to see if BMW came up with their own design or just copy the system VW/Audi/Porsche uses...the comparison with the highest spec 911 boxer that has equal design features and rpm levels shows that BMW obviously left a lot on the table when it comes to specific output to make them reliable,torquey or good for low octane gas...or EU-5 compliant minus the final EU-5 mapping...due for MJ 2020 for all new bikes or MJ 2021 for bikes already out...So if a higher output R 1250 S becomes reality I would suspect it to appear in November at EICMA...:thumby:
As in 2021 the fun as we know it might be over with really lean running motorcycle engines that sound like lawn movers...:(
Enjoy while you can...:thumb2
 
More bollocks. This is a technical section, if you want spew shit then there is a specific place for that on this forum - linky: http://www.ukgser.com/forums/forumdisplay.php/4-Beakchat-and-Bollox-(the-virtual-Pub) - it even has rant section to get it off your chest.

The problem with getting more hp from the boxer engine is 3 fold if I have a quick think. 1 - The heads only are watercooled, 2 - The higher specific output requires a lubrication system to cope (lots of info regarding tuned HP2S engines on pelican parts - which by the way has a very lively Porsche section - and the issues with oil flow and modified oil pumps) and different engine internals for reliability, 3 - Noise regulations restrictions meaning the mechanical noise the engine produces. Yes, the Boxer engine can produce more power or any production engine for that matter. No, BMW is catering for its existing customer base. Reading between the lines it means that the motorcycle owner is getting older, wants a comfortable bike that is easy to ride, can't be bothered to travel many miles for servicing and is more likely to take a pillion now that some disposable income is available. As for an S version, dream on. Rumours has been around and many an artist sketch from Wunderlich but given the fact that less than 700 R1200S's were sold in the UK and not many more in the states the economics of it doesn't stack up otherwise BMW would have been milking it.

Variable Valve timing, do you actually know what the purpose of this device is in an engine? Let me enlighten you. By altering the way the engine breathes air and scavenge exhaust gasses you can get a more linear and higher torque output across a rev range. The fact that you produce more power is a byproduct of the equation where torque produced = output in Watts if time (s) is used for calculating the rate at which work can be done. That is why the duration of the lift is altered and this gives you a different (longer in terms of angle) overlap for the scavenging at higher rpm. VVT+L is something totally different as used by Porsche and has no resemblance to Toyota, Honda or BMW designs and you cannot draw a parallel to a BMW boxer engine. Too technical for you, I'm afraid I cannot dumb it down any more. Other members on here who has spent a lifetime working with stuff like this are more than welcome to add to this. I just studied the theory and have a passing interest but you are in outer space.

Still set on Porsche engine crap and other shit you like to shout about. Yes I have had less issues with my R1100S that any GSA I owned over the past 9 years. A much older friend has R90S that he bought in 1978 and swears it is the best bike, also has an HP2S and LC GS and cafe racer in build process. And my LC GSA is on the front page photos, one of many that forum members have submitted that evokes memories of the good and not so good. As you are not really good with a coherent arguments, one can assume that you have less to offer than Norfolk Tiger and that takes some beating. Now fuck off.
 
Tannenbaum you are the typical know it all know nothing that can't even read...
The point of my thread was that according to MOTORRAD the VV-L system has nothing to do with the schaltnockenwelle/2 cam lobe system used on the new 1250 GS !
You are a total & complete idiot...:D
And now ride your R1100S the best BMW ever made that is sooo superior to any GS-LC...:comfort
Oh well at least you are funny making an azz out of yourself :thumb2
 
No, the point of your thread was a direct comparison of a Porsche engine to the BMW boxer. You have received and not understand information why it isn't by having a rant and now after wiping the sleep from your eyes the same shit starts again. Another reference to one of the motorcycles I own. As I said, a brilliant thread for the technically illiterate. You sound like a man who has got more dick than balls so, go forth and fornicate with yourself. You are a cancer in this forum.

If the mods can close this thread because all that can be said has been said. From here on all that will be posted is bollocks.
 
Tannenbaum you are a real tannen-Baum and got hit by every branch...:D
I make this post to point out that the new 1250 heads most likely have nothing to do with the alphatechnik VV-L design but are like the ones VW/Audi/Porsche uses and you call me an technically illiterate idiot saying the Porsche heads are totally different than the VV-L heads from alphatechnik...LOL
Who is the real idiot...:D
Can't wait to see the new heads...:thumby:
As for the R 1250 S boxer don't be too surprised to see one as a dealer told me there will be another new 1250 engine with higher output coming...for a new S-boxer :thumb2
If BMW learned from their mistakes it will be as practical as the R1100S was and not neither sportbike nor tourer like the R1200S...should be a great bike generating some sales for people who don't want to ride a GS but something with a boxer but a little more exiting...:)
I'm game...:D

How about you just ignore the thread.

Boxerlust has his views and opinions just like you have yours. Just because you don't agree with it doesn't mean it needs to be closed.


.... I make this post to point out that the new 1250 heads most likely have nothing to do with the alphatechnik VV-L design but are like the ones VW/Audi/Porsche uses....
Dude, you have made your point and clearly others don't agree.

Instead of continuing with this one how about we wait until the Autumn (sorry fall) and see what appears..... deal?
