A race bmw 316, m10, s14, m20, turbo, na, its been the lot!

Going along with the blocking airflow to the tyres idea, Is there a way to channel the break heat out into the rim only with airflow? Might help put a bit more temp into the tyre....but could also overheat the brakes, so maybe not.
And as for the needing £1000, If you want to fit/convert my capri to EFi for me you can start the fund

i could duct air to the brakes, although i dont think they would have an issue anyway, they get plenty of cooling air through the wheels and had no issues with stopping from almost 160mph lap after lap at snetterton

re capri, yes as soon as one of the cars i have here on "holiday" has gone home which should be very soon

You couldn't possibly be talking about something that's red.......and isn't an Alfa?

I was thinking more along the lines of trapping the hot air off the brakes from leaving via the wheels, just getting trapped in the rims. Though it sounds like a silly idea on 2nd thoughts!
Also, im pretty sure sliding would heat tyres faster then grip, maybe over turning the wheels a bit on cornering may help a touch, would have to deal with scrubbing and a bit higher wear, but might assist the heat side of things.

Oh my giddy aunt........roof sorted too?

Could you not give me another 6months.......i seem to have another collection parked round the back!

it doesnt work like that, the best way to get heat into the tyres is too make them work, as grip causes the rubber to flex and heat up and as it heats it grips even more then the rubber flexs more and so on the tyre get hotter and hotter this is why tyres can go off if you push too hard for too long on a compounnd that isnt quite hard enough,

its just like bending a thin piece of metal back and forth the bending(flexing) causes the metal to get hot much more so than by dragging it along the floor would do

Re: A racing bmw 316, hopefully the worlds most powerfull Atmo M10

meant to right this yesterday but forgot

I dont mean to afend anyone else on here who gives advice but id put in the tyre pot because of all the advice graham gives out i wouldnt mind giving abit back as a way of apreciation

dont wanna seem like a kiss arse cause im not i think itd just be nice to be able to help

I can donate a few rubber bands, would make a nice soft compound

Re: A racing bmw 316, hopefully the worlds most powerfull Atmo M10

yanked the diff back out the car, wasnt expecting to pull it to bits so soon, but then again i didnt expect an engine with a cam that alledigily peaks at 8K to peak at 6.4,
i'd expected the big capacity to pull the peak down to 7 maybe but not that low



tightening up teh pinion nut on the 3.9

luckily for me i'd had the forsight to mark up the pinion nut and keep it together with its origonal ( unworn) bearings collapsable spacer and casing, so puting the pinion back in was litterally just a case of reassembling and lining up the dots, the rest wasnt quite so straightforward because i used the ouput bearing housings and bearings that belonged to the lsd rather than the casing to which the cwp belinged 3.9, it felt good when back together and "blued" up ok

i might add this sort of stuff really should be done by someone like tom fostek who actually knows what hes doing, rather than me who only sort knows a bit, unfortunatly tom cant afford free and if its more than free i cant afford it!



changing from a 4.27 to a 3.9 doesnt sound a massive jump but it makes a big difference especially when running huge 18 inch wheels like i am
i'll list speeds in top gear which is a direct 1.1 5th at peak power and at 7,000 which is where usfull power takes a dive

4.27 peak 113mph 7K 121mph
3.9 peak 123mph 7K 133mph

to behonest at a short circuit like brands i dont think the ratio change will effect lap times much but it will allow me to get from druids to graham hill without making either 3 gearchanges or revving the engine to 8.2 so it wil give both the engine and driver an easier time

Graham
Does the series you compete in ever bring you to Mallory or Donington? I'd like to come and watch a race and see the cars in the flesh.

Re: A racing bmw 316, hopefully the worlds most powerfull Atmo M10

mallory very occasionally, donnington is just too far north for most of our competitors to go in big enough numbers to make it worth the trip

Re: A racing bmw 316, hopefully the worlds most powerfull Atmo M10

They are at Silverstone which isn't a million miles away.
Silverstone is probably my least favourite track as far as spectating goes, but it is worth the trip.
It's over a hundred miles for me, but I have done it twice.
(Brands is over 200 miles and I have done that twice too)
