williams2 v x reg bmw 530

[Coops]

8-10 car lengths? thats a fahookin long way in front!!

[david932]

but doesn't the gearing on a williams make it quicker than its power to weight?

the bhp figures u quote are at the flywheel. being rwd they will have more transmission loss through the propshaft. and still weigh 1.5 ton

shouldn't be too hard to beat for a mildly tuned williams

i definatly had no problems passing him between 80 and 110

He must've lifted mate. At those speeds it's the torque that starts to show and the 530s have a fair bit I'd imagine. That's why the willy bums the valver once beyond 60/70

Willy's about as quick as it's power to weight... in fact it's pretty much bang on. the only thing they do with regularity is make over the standard quoted power. i seriously think the guy must have backed off, as a cam'd and mapped Williams would struggle... my money would still be on the BM at those speeds... easily. it's more power, more torque, geared for it and more aerodynamic.

LOL

yeah maybe a 170-175bhp cammed chipped williams may struggle a bit but mine is running 192bhp. thats 195bhp per ton. in my calculations((230/1700)*1000) a 230bhp bmw weighing 1700kg only has 135bhp per ton. areodynamics only just start to come into effect at the speeds we were going. top speed the bmw has the advantage.. but by less than 10mph. if u look at the facts and figures on paper theres no reason why i wouldn't abliterate him

i cant believe that when some1's obviously up for giving thier car some stick thier going to ease off when a car that shouldn't be gaining on them is. but anyway...doesn't matter really i suppose

[J o n]

what mods are you running to get 192bhp? if your running that kind of power maybe then, but still not so sure about 8-10 car lengths, that tells me he let off some. they dont weight 1700kg's either, about 1600kg's and the stats for letstorquebhp if that's where you got them are prolly way off the mark... the older 530's can do 15.2 SQM's standard, that's with just under 200bhp iirc... not bad really, so motorway speeds they will haul ass.

some people let off as the speeds start to break the limit, my dad used to give our old Maxima 3.0 V6 some serious stick in 2nd when getting up to motorway speeds... he'd change to 3rd about 70mph and storm on to 80 before sticking there... ive let people go plenty of times when the speeds start getting silly, especially when the conditions are not favourable or there are other road users about, i guess it depends on the day itself and the sort of driver. some people dont care and will happily go to the limiter in 5th just to gain some advantage if they can, some wont...

cams timed with verniers, headwork angled valves, ported, polished etc 4-2-1 supersprint, scorpion exhaust, decat live re-map@ chip wizards, group n clutch.

got the figures from parkers^^ and sorry u were right the petrol weighs 1635 and the deisel weighs 1700. but thats still only 140bhp per ton

the road was a dc, open for as long as i could see, wen i dropped it into 5th and eased off to about 100 to take my slip road he went tanking past me so i guess he was ok with the conditions and speeds.

maybe he did ease off.... or maybe he just didn't have enough power!

Does sound like a pretty drastic comeback but if you say so.

Am i correct by smelling that thejesus is a BMW head now!? Booooooo :D

Heh, doesn't matter what happens on a straight with a clio - it's the NOT winning the roundabout that's the shocker, IMO :D

That's one beemer driver with "I thrashed the world's best handling hothatch on a roundabout" story at the pub. And his mates would be telling him "No way" and that you must have backed off. :D
