along that line of topic, I went to a presentation by the engineer (Tony Wallis) who designed the Bishop Rotary Valve for F1 Merc engines...but was subsequently written out of the rules, apparently due to renaults influence on the matter.

interesting design if anyone wants to look into it. Beats poppet valve, pneumatic or otherwise hands down.

A links for those interested.

rotary valves are nothing new. IIRC there was a rotary valve head made back in the day for holden grey motors. Dunstan or something. And I doubt that was the first. Rotary valves have always looked good in theory, but have alot of problems in practice.

That was a different design.

There was also a French engineering company that designed a rotary valve f1 engine in the 80's (similar design to the engines you're thinking of) but I think they ran out of money?

The dunstan engine.

Aussie designed BTW.

Speaking of cylinder head design, I'm very much looking forward to seeing productionized versions of the 'Free Valve' infinitely variable pneumatic poppet valve actuation system Koenigsegg have been working on with their engine partner. Don't think solenoid valve actuation will ever be a reality with pissy low-voltage car electrics, but this other system has promise.

No, that's exactly the same design principle, only difference is in the execution. Dunstan head runs the rotating valve shaft longitudinally with a port that opens to orrifices in the head casting, BRV runs individual rotary valve shafts at 90deg to the crank centerline necessitating a complicated gear drive system and completely incorporates the port into them. Same idea, different execution. The rotating disc valve is a different design, but shares the common trait that they really don't work reliably!

the significant difference is you can see actual images of a real life Dunstan rotary valve head, BRV ironically only had drawings of their design in that article about how they finally made one that worked!

its just a more effective way of a team getting exposure then a normal sponsor....
just like this shithouse 'jandal' crap, was funny when he said it, but getting f**king annoying seeing it plastered everywhere...

And it continues....thjis time STR . Form Autosport

on JEV.... "While there's been some bad luck this year, the fact he has made Q3 three times (and would surely have done so in Bahrain but for a sudden change in the fuel-flow meter readings that forced the team to turn down the engine) shows he has emerged from the biggest disappointment of his career a stronger driver."

Would be simple to throw a bit of redundancy at them by getting them to run two meters

I was at the Sydney Retro Speedfest at Eastern Creek last weekend, and among the classic cars they had there were some old F1 cars, very cool seeing them out on track.

yawn... torro rosso = red bull

I've read the full decision of the appeals court - "As evidence of the reliability of its fuel flow model, the Appellant provided a series of graphs...Several graphs actually showed that parameters had changed from one lap to the other and that one cannot, therefore, conclude that the fuel flow model did not change notably... On top of this, it appears that not all parameters... were shown in the graphs"

That was their "proof" - doctored graphs and refusing to fully disclose the parameters used to esitmate fuel flow in their model!

Let's put it to rest already.

    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
    • Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
    • Hi All, putting the engine back together and everything is perfect except have this plug left over.. any ideas what it is for and where it goes? Is on cold side under the intake plenum *note not a stock plug, as everything has been modified Cheers
