Gents (anyone know where Sammy is for that matter?),
The Ariel figure was around 250 I think as it was down as expected (they all are) by Ritch on the 275 claimed by Ariel, The RS4 was being limited to 340 by the ECU I think and the CSL was at 288 (I remember it because it was 1 hp down on S2).
HTH, Matt.
lol ... indeed ... the actual printout states 340bhp at the flywheel ... somewhat down on the claimed 420PS that Audi quote ... or 414bhp to you and I ... I've been advised to take the RS4 to a specialised Audi tuner with a rolling road to get another reading.Quote:

I suspect that if it was only producing 340bhp at the flywheel Terry (Senninha's friend who came along to take some photos and enjoy the day) who blagged a trip out in the passanger seat of the RS4 would not have been as impressed as he seemed to be.
If I manage to get the RS4 on an Audi specialist rolling road ... I'll let you know the figures returned by them.
Torque on the RS4 peaked at 287lbs/ft and on the graph looks to be over 260lbs/ft from 2,500rpm to 6,500rpm ... however, I would expect an increase in this figure as well when I get it onto another rolling road.
My FILs E55 AMG has a claimed 354BHP and 390.9 ft lbs and the 3.2 NSX ( GruppeM, Tubi ) was just as fast to after the ton then the NSX takes over. The NSX-R no contest there LOL.
So HP and torque is not the whole story.

The guy at the rolling road mentioned the most important figure that no one ever really quotes ... or bothers to get a reading for ... this was the torque at the wheel ... which he said is easy enough to get a figure for after a rolling road run.
It's this figure that really can tell you what power you are able to put down on the tarmac.
Losses through transmission can vary greatly apparently ... 4x4s obviously suffering a greater loss in power between the flywheel and the tarmac.
It sounds like good news overall for the NSX in that case.
Who will ever know if the absolute numbers given to you guys are correct or not ( I have to say they look disappointing) , but its good to know that relative to other makes of car there the NSX did wonderfully...now I understand better why I mash M3's on the road every day! :-)
Blimey, this thread has sparked a bit of interest, it's a shame a few more NSX in varying mod states couldn't have made it.
As you ask Martin the Atom figure was 257 @7885 RPM and the only odd thing is that Ariel reckon they produce peak on the other side of 8000 so I don't have to hang on to the gears as long as I thought to beat them Mondeo diesels. Mind you I think my soft rev limiter is set to deliberately stop too much fun.
Torque curve was the most interesting to me as it's flat from 4000 RPM to 8000 and pretty damn good from 1500. Max was 178 lb ft at somewhere around 6-6500 but as I said earlier it's virtually flat. It doesn't sound a lot against the BHP but inside a rollerskate....
Esso 97 fuel (previously got caught out in a strange place without an obvious shell and couldn't face stopping on the way over in the pouring rain).
The lower than advertised figures did not surprise me (apparently the overhead air intake has a Ram-air effect ala some motorbikes but sounds a bit brown runny stuff to me) and as I said to some peeps there, I would have been chuffed if it was 25 BHP because the real world performance is "adequate". First gear is redundant and it's still wheel spinning in fourth if you nail it.
Unfortunately I have 3 very expensive mods to complete before I even contemplate asking the car fo more power so I will just have to put up with it for the time being.
When's the next one with the snarling Orange beastie Simon?????????????
Ritchie if you are ever in Hampshire let me know. I'd love a spin in the Atom.
Cheers
Martin
Just to keep this thread going a bit longer, here is the Ariel on the rollers.

The smile it put on that guy's face is classic:)Quote:

Looked amazing watching it though.
