[WEC] New Perrin LMP1 !

[deltawing]

1 Newton is about 102 grams, so to round it up 10N is about 1 Kg. The car is doing above 500 Kg of DF at that speed and it is paying for it with about 95 Kg of drag.

[silente]

That´s really an exciting project!

I took a look to the numbers above.

As you guys said efficiency is very high. In particular, Drag is very low, compared to other figured i saw (although they were numbers referring to 2 m wide cars, as per 2013 rules or LMP2).
It looks much like an Le Mans configuration, above all looking to the Low drag Values. After all, they clearly say in their website their aim is to win Le Mans!

It is anyway very nice to see they are sharing such infos so easily, although these are just general figures.

I guess these numbers are coming from CFD simulations, so it would be interesting to know how they have been calculated (boundary conditions or simulation assumptions, a part from speed and ride heights).

Right, if its 5200N thats about 530.2kg/1166lbs. of downforce vs. 950N or 96.8kg/212.9lbs. drag. Sounds good! Now if only someone would run the thing.

On the new website they have a donation and membership options for 30 pounds. Sounds like a good way to help the team.

Did anyone have the latest excel file from Perrinn LMP 1 where he could download the stl. files???

Or the CAD file of the hole car!!!! PLEASE :-)

The single car solid and some other parts are available on the website here - http://www.perrinn.com/myp1

Here is the excel file, I cant find it anymore on their website since they changed it. Dont know if the links still work - http://www.mediafire.com/view/gfyjsx.../BOM-myP1.xlsx

It looks like Perrin already has 120 memberships. But the webpage says they need 3000 to start the eurotour. Hmm hope they get them.

Ah, thanks for the reminder. *just signed up*
Better money spent than on taxes, unlikely to see any return on either

That was my post. I am a member and members have access to most of the CAD drawings now. About $50 USD is well worth it to me to have this kind of access. Also, Perrinn will be emailing members daily during the week before Le Mans explaining in detail their design.

Cool! Keep us updated if you can? Hope their plans come together and we see the car race.

Will do! If there is a specific part or assembly of the car that anyone wants to see, let me know and I'll try to post some pictures.

How about the rear wing mounts?

The Center Support mounts to the rear crash structure, which mounts to the rear of the gearbox:

Few interesting, blunt comments about last weekend's race:

I understood it's only for the members and if you are one, shouldn't you know?

I am not a member and I am considering to change that if I can make the presentation. So would like to know if I can make it there in time ...

Do the Perrin team have a tyre manufacturer on the project?......I'm thinking Michelin have their hands full so probably cannot justify the distraction, but surely a reputable race tyre company like Dunlop, Bridgestone, Continental etc could use the Perrin project as a leg-up into a clearly growing field of motorsport?......but didnt Dunlop close down their coventry based motorsport base due to a compulsory land purchase due to JLR expansion?......if just seems to me that without a credible tyre partner on-board at the early stages of the project, to advise on the steering geometry, suspension and aero-load interaction with the tyres, they will be on the back-foot to start with???.......and if they are trying to convince a credible race team to race the car, with huge investment, this will be one of the first questions they ask.......well I would!

Fort Dunlop is in Birmingham, not Coventry

I encourage you to spread the content of the myTeam messages on your own social media pages or even create myTeam unofficial pages.
But it is important for myTeam to send a message that all official information are accessed exclusively from perrinn,com and to Members first!
The aim is to redirect people interested in myTeam directly to perrinn.com, for the benefit of myTeam.
In this day and age where most companies feel the pressure to maintain social media official pages, myTeam is doing things differently - you are the best people to spread the word on social media.

There you go. Now I suppose "someone social" should write a script to push myteam messages automatically to this board, eh ?

To participate, you need to form a teams of Members (minimum 2).
All participants will receive something through the post, see below.

The winning team will receive the scale model of myP1 3D printed (the one that you see on the front page of our website and that now seats on my desk) - (...)

Obviously it's a fund-raiser/race to raise (paying) membership levels as well as
a gauge as to how much awareness the project can raise on its own, I wildly
speculate, to demonstrate potential bigger investors the reach and validity of
the project.

Anyways, I'm somewhat surprised no 10/10er is trying to get his hands on the
model for the appropriate photographing and publishing (i.e., here!) and general
'feels right' result of the thing. There must be one (at least). Speak up, I'll join
your ranks ;-)
