RS246 Rolling Road Meet Sat 17th Nov Thorney Motorsport

[GrahamS4]

I hear that the 300C tore the rollers up!

Note to self, must buy something that pulls them apart next time!!

That was the reason offered. My personal theory is it didn't. You were second on. The B7 RS4 was first on and was wriggling all over the place and unsurprisingly got a bad result (because of the dyno not becuse it's a B7!). I think we then had Woody's M5.

Then I think we had Chris' B5 S4. Again, all over the place on the dyno with very low numbers. Mihnea I think voiced his thoughts as I am sure a few others did.

This is when after some scratching of heads the alignment was checked on the dyno and I think the rear rollers were out a few mm one side compared to the other. After this, cars were running fine, sitting as expected, no movement and good numbers.

I personally suspect it has been a while since anything four wheel drive was on that dyno. As they specialise in Vauxhalls and BMW, maybe no surprise there.

I think the dyno was out of alignment when we arived, but with cars only driving one axel it wasn't evident.

Anyway, that's my theory.

When you said it was your daughters birthday - I did not realise it was her birth day - I see Grandad was happy

good pics - send me a dvd please

[neily]

whoops. Thanks for pointing that out Doug. Luckily the REALLY dodgy ones were not posted up, otherwise me and the wife could have been very embarassed !!! ........ Even Julian would have been embarassed by them....

[DavidT]

Even Julian would have been embarassed by them....

Dunno about that, I've never seen him embarrased family is what matters matey

Great pics, looking forward to the video, although as stated earlier, I doubt it can convey the 'pain' of a rolling road session. I'd forgotten

[S4TAN]

Even Julian would have been embarassed by them....

Never! Nothing embarrasses me ... not even myself!

[neily]

Never! Nothing embarrasses me ... not even myself

Something tells me that is very true !!!!!!

[Harper--D]

Just as a note, those who ran before Cliveh with SM's i would expect to have high intake temps, it was the first run i had chance to watch i was so busy... and then just before they started the run i realised they had only being using 1 fan for all the cars facing the centre of the car, which is of course no good for cars with SMIC, so i politely instructed them to use 2, 1 at each side for cars without SM's. Hope that might explain issues, dont know the running order as i wasnt there most of the time!

Looks like it was a great day out. Pretty pissed my clutch has gone and couldnt make it.

Well my standard-ish S4 mustered-up a decent 269.9 BHP - 340 Ft/lb at the crank which they translate to 198.4 BHP - 262 Ft/lb at the wheels.
I'm pretty happy with that

Mods (aside from the chassis) comprise RS4 clutch, intercoolers c/w APR hoses, APR bi-pipe and an MRC oil cooler.

Was good to meet up with folks again, thanks to DavidT and Neily for their efforts.

Overall everyone has some great results. Im confused as the varying torque results though. Might have something to do with certain mods done.
I always thought a stock S4 pushes around 280 lbs/ft at the crank. and it was a stage 1 S4 that produces around 350 lbs/ft at the crank. Nice to see the horse power figures was pretty accurate.

503.8bhp and 525 ft-lb for me. Was hoping for a bit more as I get close to 450g/s on the maf. But it feels fast enough for stock s4 block.

I think all the cars were doing what they should nad the ones that weren't we caould see why they did not do as well.

Doug, very impressive results. What mods have you got on this car, and what coolers you running?

[DavidT]

I agree, and like I said to you & Mihnea, it shows what faith you have in your work to stand there and watch car after car be thrashed, fair play

First time i have been to one of these RR and it was quite an eye opener listening to those screaming engines. a BIG thankyou to dave for doing the pressure test for me and the grizz and s4 woody for there offers of help and advice. sorry i didnt stick around and say goodbye as the trip home was going to be a SLOW one because of the leaking intercooler.
Well done to DavidT and thorneymotorsport for organizing a great day.

[DavidT]

I look forward to people posting their own so we can do a list (please don't post anyone elses results or details)

Ooops - sorry, I posted Clive's results before you posted this Dave. Didn't know it wasn't 'the done thing'!
