If the bonnet has been on ages, does this mean i could be right?

Still got the carpet in this?
i have created a detailed graph with red.dot and pmsl performance below to illustrate the fluid dynamics vs the output of the Co ed boost. the vorticies created by the darwin sideskirts now gives me 2% more downforce than a 197 diffuser maintained on cam with the f4r output at 20% AFR=PS3xzomg whilst upside down .
whats that meant to mean?! just because they have a mild cf effect, can you even imagine the abuse they'd take, i fitted these for no other reason that they look mean as hell and lower the centre of the car ridiculously.
they arent easy to fit really and require cutting, i guarantee you'd fcuk it up.![]()
oh and the pic of the underneath of your car, you havent sheared the bolts off, they arnt bolts they are just like threaded sticks then the heat shield has holes in it that lines up with them then you just put a nut onto the threaded stick to hold it in place, if its rattling (like mine is) its because you are missing a nut to hold it in place
no its not, the thread is sheared, the bolts wont catch at all... they were bent as they are attached to the chassis so have taken a knock. a heavy impact or stress causes that.
heaven forbid i actually checked.
But this isn't taking into account the themal variant of the aerodynamic dynamics, fluid and thermal dynamics suggest that as the air passes over the vehicle and creates the vorticies you speak of that they heat up, this then effects drag (increasing it) and negates negative pressure by a small amount. so by adding in the correct figure into the following formaula Vc/f4r-rs*fz+17.5% it tells you that these skirts drop the downforce from 2% above a 197 diffuser to 6.75% below on.
If you had put the skirts on the roof as I suggested you would have achieved the 2% above the 197 diffuser you were after, clearly looks were more important to you than actual aero gains. Next time think about thermal expansion and its effects on the vorticies.
Thanks
LOL!
I thought BrianR was back for a second.
He calculated all of that while waiting to come on cam.
sorry rich, your idea was great and when i ran it through a CAD setup i found 844>/xf wasnt pushing the centifuge down to my specification... alas i have just spoken to eric boullier at renaultf1 and have some exciting developments.

wear an extra pair of socks if you really must
apologies, now f**king come and bleed my brakes you leicester pikey
Poor Rich! IIRC detailing is hard with three wheels off and two brake disks to go on? See below;

Unlucky mate. Gutting.
Free PC cheer you up?
It will live again, no doubt. I still think a replacement engine with fresh belts will be the best/cheapest/most reliable long term solution. Be nothing worse than spending a few hundred and the problem still being there.
