After only having the RS4 for a few weeks I pulled up to work one morning and all was fine, jumped into the car at lunchtime and it wouldn't fire. After taking the original fuel pump out we tested it on the bench, would you believe it the thing seemed to work! We checked all the wiring from the fuse board to the pump and that seemed fine. We figured it must be some kind of dodgy pump regardless and changing it was the best course of action. Checking out the price of a new OEM pump we figured it was almost the same price to get a Bosch 044 pump (rated higher than the OEM pump) and the necessary basket/filter best suited to fit that pump. - view gallery

Had a great day out at Castle Combe again for the Audi Driver International show put on by Autometrix. It's the first time I've been and have to say it was rather quiet, speaking to a few veterans they commented that it was by far the quietest the show had been for many years. Last time I took the car on track I was disappointed in how it handled so earlier this week I wound the AST's to the hardest setting and adjusted the Neuspeed ARB to it's stiffest setting... THAT DID THE TRICK!! Car felt a million times better, really went round the corners well, transformation was like night and day really. Car went like a dream too, even un-mapped it just pulls like a train to the red line so goodness knows what it will be like mapped! - view gallery

The B5 RS4 comes with a BOSE speaker system as standard, however most of these components are starting to get tired and failing after 10+ years so it's only a matter of time before the need to replace the speakers becomes an issue. My drivers side door speaker had been crackling on and off pretty much since I got the car, sometimes I just wouldn't bother turning the stereo on at all but ultimately it needed replacing so I figured I'd replace the lot - view gallery

In order to keep the fuelling nice and safe with the power targets I'm aiming for it's necessary to fit some larger injectors. Whilst I've heard some good things about Seimens 630cc injectors it does seem the default option for fitting "bigger injectors" to the B5 RS4 is to go with the Bosch EV14 with a 750cc rating. Handily one of my contacts knows where to get them from and sorted me out with a set. They don't look like much, in fact they are really small compared to most injectors (the B5 RS4 taking a compact fitment) so in another way I'm glad I got them for a cracking price rather then what most resellers charge! - view gallery

With the Milltek System and 3" Downpipes now fitted it was time to visit PowerStation and see what difference it's made to the power. Turns out quite a lot which isn't really that much of a surprise! Figures this time where much more what I expected with a result of 396bhp and 342ft/lb which is a huge increase from last time - view gallery

Having sorted a full Milltek Exhaust System & 3" Downpipes it was over to the chaps at e-parts to get the system fitted. I don't envy them, it's a tough job doing the downpipes at the best of times! I stuck around of a bit but left them too it, will be collecting tomorrow and can't wait - view gallery
