fats: 2.8 on a dodgy rs4 box

MAF peak: 450

[rolskii]

mine : B5 S4 - rs4 injectors, f/pump, i/c's, k04's, fat head gaskets, opened up airbox, AWE flat panel filter, rs4 pre-gutted d/pipes, customed 3"milltek & MRC map .... dont forget the miller light experience of the de-meshed MAF.....

Dyno results: 390.1 bhp, 420ft/lbs
Best Fats run:(3.9)

My Car :
2000 S4, K04s, tubular manifolds, 100 CPI cats, custom exhaust, FMIC, 720cc injectors (600 cc injectors at 4 bar differential?), RS4 MAF, 044 fuel pump, K&N cone filter. Bits of the intake are lagged. N249 delete. Horns relocated to make way for big oil cooler


499 bhp @6000 rpm, 515 ftlbs at 3600rpm

Best FATS (not on the day I had to be elsewhere) = 3.02 seconds.

Doug, 'keep s4 rods in the block' - you're starting to worry me!. I was going to aim for a few more ftlbs.

Doug, you can update you're profile now: Audi S4 5?? bhp

Good idea on specs Clive, keep em coming, they make very interesting reading

Spencer - no more torque for you! I think we are on the limit on s4 bottom ends - just for longevity and that one time you get a batch of crap fuel it is better to say on the safe side of the max you can get from the bottom end! I think you will struggle to get much more out of the car as the turbos are pretty well maxed out. Rods, lower compression and bigger turbos is your next stage - and brakes!

I think the power and torque figures we are all getting is pretty amazing for not changing engine internals - not many manufacturers engineer their cars to take this much abuse.

Car: B5 S4, K04's, 600cc injectors, RS4 i/c's, Milltek de-cat d/p's + dual cat back, walbro fuel pump, MRC map.

405.9bhp, 510ft-lb

best FATS: 3.70 (Clive's just sent me my logs and there's a 3.70 in there - a whole 0.08 seconds better than I originally thought )

[DavidT]

Who is collating the data for the FATS runs from the day please? I can't remember.

We should have best & best on day against the data I suppose. My average at this spec is 3.65, but the one from the day is 4.03.

[rolskii]

@ Spen .....impressed dude ..... need some of those manifolds ..... grrrr ....

[whisky180]

great day, nice to meet everyone, although my nuts are still thawing out. big disapointment with the power figures (515 bhp & 450 torque) but fortunatley Doug and Minhea are taking the car in tomorrow to sort it. will be putting the car back on the rr so will post revised figures asap. big thanks to everyone who made the day possible

[spen]

D'oh. I'll take that as a warning then! Yellow card, no more 28psi mid range

Brakes. Check! Number two on the list. Number one is the oil leak. And a new windscreen wiper motor at 1.5.

[DavidT]

Yeah and your sig still says mildly modded. You need a B5 to get away with that

[CliveH]

Who is collating the data for the FATS runs from the day please? I can't remember.

Well I volunteered, and we have all the data on my laptop from the runs that David (Harper) did, but I think there are some more to collate?
