IanH's 955hp V10 Audi RS6 - Another Car Diary!

With much less drivetrain losses (so more wheel HP) and a better gearbox a stage 2 F10 running around 750hp-700ft/lbs should easily be a few seconds quicker to 200mph I reckon.
Yeah when your at this level of power maybe drivetrain losses aren't as much of an issue..- *EDIT***

740bhp can now be had without any bolt ons on the m5 which means it's pretty cheap to join the 700 bhp club
Well after 3 long tortuous months with the car away with MRC Tuning I'm just back from picking her up with 920hp and 830ft/lbs!!!!
Initial impressions - HO.........LY...........PO..........OP she's fast!
Sadly the weather this afternoon (and the multiple crashes people love having on the M25) made for a pretty sedate run back to Kent but for about 30mins after I collected her and it was still dry, she was stupidly fast, even breaking traction in 3rd which is a first for me
Originally the car was mapped to run 7000rpm but the mappers realised that the extra 500rpm made no difference as the "trial fit" Intercoolers I'm using don't flow well at high RPM and were having no effect on the power in that last 500rpm so we've gone back to the OEM limit of 6500rpm, smoothed the curves out and left it with a little extra available if I decide to get better IC's (10-20hp and another 80-100nm we guess).

The Spec is -
Stock Engine Internals (rated for 1200hp, thanks Audi!)
TTE850+ Turbos
Uprated Gearbox
Uprated Injectors
KWE Intercoolers and Silicone Pipes
Aquamist HFS-4 Water Injection
Ceramic Coated Intake pipes
Race air filters
3in De-Cat Downpipes
3in KWE Exhaust
I think thats it, I really should make a proper list!

You mentioning how high the internals are rated begs the question, why not go for 1000bhp? It looks like you'll be at around 950bhp with a better IC, was getting that extra 50bhp going to be far too expensive, time consuming and risky? I imagine the gearbox must be near it's limits with that torque figure.
legless Alex - The turbos run out of steam around 950-ish on UK fuel (another car has hit 1024hp with them on 109RON) and there's no space left to fit bigger ones unless you do an unbelievable amount of chopping in bit's you really shouldn't chop into (chassis legs etc!)
The GB is rated to over 1200nm (already 2-3 cars running that happily) so my only "issue", for want of a better term, is the IC's. Do I spend £1000's again just to make 30-40hp when what I've currently got is good enough? I'd have to see price vs performance before I decided.
