This technical stuff is all nice, but what about WRC's real problems?

[Sulland]

Pop-off valve is a valve that restricts the turbo boost to a pre-set max turbo pressure.

Shuricks rules look like a combo btw old Gr S and formula 1 rules !

Normally aspirated is a clear possibility in my book as well, but a 2.5 ltr engine is enough I think.

And Josti: what are the real problems ?

[Josti]

Read the forum Sulland.

The wastegate is what restricts the pressure, the pop-off is the valve that releases pressure when lifting the throttle so that the pressure doesen't bounce back and slow the turbo down. Lies pretty much in the names doesen't it

Sorry you are of course correct !

Josti: Sice its a pretty big forum, could you pls give a couple of hints to what you feel is the real problem ? Maybe a link or two ?

[Josti]

This thread sums up the problems pretty good:

In the past we had driver's battles. Now, it's all about technology and money. That's wrong

I fully aggree with the statement above. And I hope that FIA will see this both in F1 and WRC before it is too late !

In my opinion all changed when the car manufacurers entered the scene, and Richard started his commercialisation program, to become the Bernie of WRC.

To a certain extent it had to come, but it went overboard !

All motorsport need to be made so cheap that everyone can buy one or more cars and set up a team ala in the USA.
That means that technology used needs to be so simple and mechanical that it is possible to understand and maintain over time.

Today very few if any privateer teams can expect to fight for overall victory in WRC - and that is wrong.

So I am all in for getting back a simple and "Analogue" car as the top class in WRC - so the drivers get back being the most impotant part, and not the car (manufacturer) !!!

Oi Oi Oi Gutte little correction.

Wastegate which is controlled by the wastegate actuator, allows a portion of the exhuat gasses to bypass the turbine wheel, when needed, to control turbine speed.

"Pop-off valve" in the context of a maximum boost limiting device is a a valve located in the "log" or plenum which when whatever pre-set pressure is reached will allow a valve to raise off off seat and dump the contents of the plenum and kill any further boost for a given time.

Pop off valves have been used forever in US "Indy" type nonsense for years, the idea is if you exceed max boost you pay a big penalty.
Here's a artical that talks about the collection of crooks, bandits, and fools that have to deal with this nonsense:

There are photos of "pop off valves" there.

The thing that you described to prevent the slowing or stalling of the turbo during the period when the throttle is closed is that beloved toy of children everywhere the "Blow off valve" or BOV, the term which is the single most frequently used word on hundreds of performance forums worldwide.
Woooooosssssh!


Hoppas det förklarar skillnaden för dig.

Sulland, not to sidetrack the thread here too much, but when you say like USA after 'motorsport need to be made so cheap that everyone can buy one or more cars and set up a team' you should be aware that in US over the last 8-9 years has steadily become so expensive that only independently wealthy people can afford to afford do do more than 2 or 3 events.
Costs have soared, event stage distances have reached absurdly short levels (imagine the costs to drive 5500km one way, pay an entry fee of $1100, and have 105km SS).
Only millionaires or their offspring can afford to do that.

The trend is not reversing.

Only bright spot is the debut of an independent initiative called 'Max Attack Series' by a group of people who are most impressed with what they have been pointed to on the Swedish GpH and Finnish GruppF series.
Max Attack series is run concurrently with 3 rounds for 2wheel drive vehicles only, no homologation requirements, and with actual good prize funds of $2000 for 1st and even $800 for 5th.

Other than 'Max Attack' the US series is a very bad joke with guys with zero car competition experience but HUGE budgets buying insanely expensive cars cars and instantly making top 5 results proving only how thin the competition is---or alternately how virtually any man off the street could do the exact same thing----with the same budget.

I hope it will be but i don't want no WRC cars with 1.6 or 1.8 ltrs! Love the sounds don't restrict the volume..

Oh please....
