Project: S2 Coupe Continously upgrade

[Audi_CQ]

I only have G-tech pro RR measurments that says 355WHP measured in 3. gear @ 1.7 bar. A wild guess: 420-430 crank HP

355 + ~30hp air resistance = ~385@wheels = ~450+ @crank I quess

355 + ~30hp air resistance = ~385@wheels = ~450+ @crank I quess

I also think that is more right, but I like to roand off downwards when it comes to "guessing" HP figures

[s2driveruk]

whichever way you look at it....they are tidy figures

I like the fact that as well as bhp ypu've gone for weight reduction rather than fitting a bigger stero and electric seats.

[s2driveruk]

ummmm you lost me there Jamo? I know i am due some caffeine but even so......can you explain

[s2driveruk]

we're not all the same for many of us the S2 comes alive when let loose on the smooth tarmac of a track wich is a pretty good reason to up the power, tailor the setup and shed the weight

Mine started off being what you describe but the longer I own it, the more it needs to focus on track and be compromised for the road...though the A/C stays

[Rusty]

That's part of the fun, lots of different ways of doing things. Weight is the killer of performance tho, if you can find ways to remove weight and keep your creature comforts then you're in teh best of both worlds for daily use.

That's the same for me. I don't have the money for big bhp so I've got to use what I have and maximise it. Plus I've always wanted a track focussed car.

[s2driveruk]

i guess you could flip it and say whats the point of huge BHP for road use where the limit is there to be enforced....I haven't got as much shove under the bonnet and many on here but what I do have I can use to the max without fear of a ticket or a NIP

Its not an obvious trackday choice I'll grant you but its fun learning to live with or work round the compromises the S2 offers up when used that way...

Quite simple, don't carry any passengers . I want an ejector seat 2fast 2furious stylee.

Anyway back onto the project looking very nice

[Rusty]

That Nokia application is good fun! Will take it out and do some proper runs now that I've got to grips with it. Have just been looking at some normal driving that I did with it and there's so much information there to play with.

Do you know of any other car based applications for the N95?

[s2driveruk]

nokia applications....? is that the gps function?

[Rusty]

Yeah, look at the racechrono link above. On internal GPS it's only 1HZ but with a £30 GPS receiver you can get 5hz and an accuracy of +/- 0.15s according to the website. On 1Hz accuracy is +/- 0.25s for performance tests. Not that bad for something like a 1/4 mile but a country mile for 0-60mph. There's a 100-200km/h and a 80-120km/h test that would be good (on a priveate test track of course).

For free it's the mutt's

[s2driveruk]

oh very nice finally a good reason to steal with wifes E72 See castle Combe is already available...whole new angle to ADI me thinks next year too.

[Rusty]

Best keep it quiet though as you're not supposed to use lap timers on track days, I think it has a habit of invalidating their insurance
