Tyre concerns

... if this report proves correct (e.g., 500 BAR?), then the Daimler-Mercedes 2015 power unit is slated generate, minimum, 1200 rwhp:

Trouble is, Pirelli doesn't have a tyre sufficient for 2900 psi, let alone 7200. With that kind of output, Pirellis going to have no choice but go back, to engineering real competition tyres. Charlie's going to have to revert F1, to staggered 70s style gumballs.

Perhaps 6-wheelers (4 at the rear) - asj.

 

Your confusing boost pressure with the direct injection fuel pressure. The direct injection pressure won't double the engine power, not even close. It may allow them to run more compression and hence get some more bang out of the fuel, but we're talking single digit prercents, not doubling the power...

 

Yes but other than that his analysis sounds pretty accurate to me

 

Haha, yes +1!

 

+2

Would love to see a tire capable of *holding* 2900 psi....... Much less 7200!

Oops!.....

Yep. Word on the street is another 40-50bhp just from the engine, so who knows what more they will be getting from their kers system.

 

Just read that what made Mercedes' PU so powerful was also an additive used by Petronas in their fuel or oil, which explains why Mclaren using Mobil weren't as competitive.

 

First, the injector pressure is limited to 500 bar, or about 1350 psi. To accommodate that requires a redesign of the injector.

To put this in focus, I own a car that has injector pressure of a little over 27,800 psi. Mind you that is via a pump injector. This was about a 6 fold increase over the prior version. The increase in power over the previous engine, w/o the pump injector, was in the neighborhood of 10%. The benefit of the increased pressure is better atomization of the fuel and therefore more complete combustion, releasing more energy.

With F1's restrictions on fuel flow, fuel pressure and boost pressure, this sort of increase in ICE power (to 1,200hp) is impossible.

 

This thread goes to show exactly how much the thread starter, asjoseph, actually knows. What an idiot. Go away as all of your posts are worthless and take up way too much space in this section...

 

I don't know, he does bring a certain excitement to the site. I'm still chuckling about the 720 psi tires.

 

If I was unkind I would say a 14 year old pretending to be 44..

I think he probably got bent over by his bookie last season.

But in all honesty there was a news program here in the US that said kids shouldn't be playing on turf fields because they're made from shredded tires. If your kids, or asjoseph, for that matter, actually eat the tire bits, there's more problems than the actual tires. This isn't a sandbox.

 

Bingo!

 

Well... the OP isn't coming back to defend himself (permanent ban), so let's move on from bashing the forever banished.

All the best,
Andrew.

 

Thank you!

 

Thanks, it will do the board very well, but what is your reasoning?
Is a lack of physics or engineering skills hidden somewhere in the fine print as a reason for punishment?

 

I can see how that was unclear, sorry about that. He wasn't banned for any physics or engineering reasons. Click on the link in my message above to view the ban application in another part of the forum. An abrasive history on a couple of topics in the past and recently revealing a very low opinion of Ferrari owners lead me to believe FerrariChat wasn't the best online venue for him and that it wouldn't be pleasant for us to keep him around either.

In F1, I just wanted to draw attention to the fact that he would not be able to respond because he is no longer a member of our forum, rendering further criticism/feedback directed to him moot.

All the best,
Andrew.

 

Thanks Andrew!
I overlooked that link.

 

I can take him off my ignore list now.

 

he'll be back with a new name in less than 24 hours i bet ya!

 

Our mods are better than that.....

Besides, his, unique, way of, punctuating, his sentences will, immediately, reveal his, ruse....

Good riddance. Get rid of a couple of others and what we consider 'normalcy' may just get restored......

Cheers,
Ian

 

Yes, he is, definitely, "commatose".

 

Just from my experience as an aircraft loadmaster, after a certain PSI, tires are not considered pneumatic anymore, they're considered solid. I think it might have been 100 PSI and above.
