a little clip of it on the rollers showing the outer injectors at work

Bloody Hell!

Bloody Hell!

Its not really that scary Dave, when the car is in action they are covered with a NASA spec baking tray

thats nuts graham... i do hope ya electrics are well protected and spark free

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

no sparks in the area, the injectors only inject at high revs and full throttle anyway, so its quite safe even if you could set fire to the fuel, the engine would suck the flames out and the moment you lift off it stops injecting anyway

last thing anyone wants to see is you having to pull the lil red puller thingy and put feckin powder everywhere

your car is wicked mate

sorry bout picks if not very good

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

pre brands fettling included fitting new front discs and pads and some stiffer front springs and shaving a couple of kgs further off the weight, but mainly to try a new exhaust, its now bigger at 2.5 inch, and a trip to the rollers confirmed it was a good move, 10bhp more, but perhaps more importantly its made the power hang on much better, revved to 7500 its 30bhp up making it much easier to keep in the thick of the powerband and not hurting performance if i need to rev it on to save a gearchange or get a higher top speed



having since driven the car i have to say the additional 10bhp isnt hugely noticalbe, but what is is the much wider flatter top end

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

arrhh just found the graph showing old exhaust v new, as you can see its only at the top end it benifits, we had to add more fuel and take a lot of advance at the very top out, changing the exhaust without a remap would of probably melted something

Re: A racing bmw 316, 240bhp Atmo M10

the day before the brands GP meeting i did a test day on the indy circuit, its purpose was to scrub in my new slicks and bed the brakes and get a feel for teh stiffer front springs rather than try anything new,

clearly the tyres came up to temp much much faster and felt plenty grippy, im sure the car was faster especially as it felt right to chenge up between druids and graham hill rather than just stretch a single gear and thats on an engine which now hangs on to the power better, the extra 10bhp didnt really notice but the fact it holds peak power so much longer certainly does.

saturdays qualifying went ok ish i should of gone well afterall last time i did the gp in 2006 i was 3rd overall although i was running the turbo then so effectively i was driving a different car this time, around the indy part of the circuit and upto westfield i felt happy, but the next few turns i never really got to grips with the circuit the car had loads of grip just not very fast but to be honest it was probably more me than the car im not gear at learning new circuits especailly ones like the gp where most the corners on the gp loop are back to back without any sort of straight between them , coming back on to the indy the backend felt twichy so maybe the current minimal spoiler config wasnt helping, after a couple of laps i ended up on circuit alone which didnt help as its easier to get a "tow" round with someone else and ended up bulked by a couple of cars on my last two laps

in the end i qualified distinctly midfield with a 1.47 leaving me 22nd out of 44 and a couple of seconds of the the pace i really needed, i wasnt too worried though as i was sure given a decent start i could make up ground.

off the start i pretty much held my own almost out dragged one of the class B turbo seats, first time round druids saw clouds of dust as richard brent went gravel trapping at druids, he was lucky to get out of it and slotted back in somewhere near the back of the pack, unfortunatly a lap later saw a bmw in the gravel at surtees cause a safety car deployment, which meant 3 laps behind the safety car following the safety car richard brent came past at sterlings he had way more speed than i did, although i didnt want richard in front, i felt i could stay in touch with him and make progress further up the field, unfortunatly on the next lap nickwilliamson ended up in the gravel trap at westfield causing yellows which initally i was pleased about knowing i could close up on richard who was immmediatly behind andy woodsdean, who was on the back of dave usher who was my target, it would seem though that richards car was so ful of red mist he didnt see the yellow and he dived up the inside of woody, as i couldnt attack under yellows my chance to try and hang on to richard was gone, and the next lap turned out to be the last, having lost basically half the race to the safety car the COC's had considered letting it run another lap but with the car in the gravel right at the circuits edge they decided on safety grounds that race couldnt run on, so that was it game over, i never had a good lap and finished 19th which if you take into account cars that were ahead that didnt finish i neither made or lost any places,

i still felt i could do something in race two, if the weather held out, it didnt!

i had no problem with doing a wet race as i have a decent set of wets and the cars pretty stable, unfortunatly by the time we were on track doing the warm up lap it was severely steamed up, we actually did two warm up laps under the safety car by the end of the second i couldnt see a thing and nearly pulled off before the start, in the end i did take the start, got to paddock and realised i couldnt see anything not even the bright orange clad marshalls who normally stand out a mile, i picked my way round, got to druids only to find i couldnt see any of the brake marker boards or anything in my mirrors, i made it safely round druids into the muck and spray from cars ahead of me and did some quick thinking, i did consider circulating slowly so as to score points, with virtually non existant forward visibility as with fogged up side windows no rearward in my mirrors i decided it was just too dangerous for everyone for me to carry on and pulled off at surtees .

so that was it game over for the weekend, i have to say i did quite a few wet races in my old car and that was fine, i only did one previous wet race in this one, which strangly enough was the 2nd race i did last time i was on the gp circuit at brands, the car misted up then but not nearly as badly, and this time i had done the rain x and fog x precautionary stuff.

Re: A racing bmw 316, 240bhp Atmo M10

its a shame about your car steaming up Graham, after seeing both you and Goddard pull off at surtees on consecutive laps I had assumed that you had both gone straight off there, possibly from oil or something sitting on the wet track, so after that I did take care with that bend.

Lets hope for some dry races for a while now, I was suprised how much grip I had but the visibility through the forest was diabolical and paddock was a trip into the unknown every lap. All credit to the circuit though, there were no lakes or streams across the track and i didn't experience any aquaplaning (although the van was on the way home )

Got to say though Graham when we got to brands on Friday the first thing we heard was your induction coming down the hill from druids, amongst all of the M3s and caterfields it looked and sounded in a class of its own

Nice write up Graham...

Re: A racing bmw 316, 240bhp Atmo M10

Shame about the fogging Graham. That'll need fixing, you cant rely on the poxy British weather being dry.

A leccy hot air blower maybe? Or additional ventilation in the cockpit. Not something you can try out really is it? I suffer the same in the Fiesta when sprinting. Not attempted to cure it as such, but then, I'm not doing 10+ laps at racing speeds.

Good decison to pull off though. Better that than risk an 'off'.

Re: A racing bmw 316, 240bhp Atmo M10

i have a few ideas, one sure way to improve things would be to go back to a glass screen, but they are so dammed heavy....................

[robt100]

Re: A racing bmw 316, 240bhp Atmo M10

a mini electric heater fan maybe?

Re: A racing bmw 316, 240bhp Atmo M10

Graham

I had the same problem, as soon as the second race got going my screen was totally misted up (very unplesant). We had applied rain-ex anti fog but it did not work. I also use a polycarbonate screen (5kg lighter). The other drivers in our camp had glass screens and did not have a problem. This is the second time this has happened, I think the answer is a fan or a glass screen. I have also been told since that rain-ex should not be used on plastic?
