Mario, this is no Twitter. You ain’t limited to 140 characters. Even they are catching on and increasing to 280. To help people express themselves better. Think about it.

some say pictures are worth 1000 words, there was a video posted last page of the dyno run. what all did you want to know?

Anything tangible would do. So far we have seen a poorly fitted single turbo which sounded awful and the back of a B5 on a Dyno? Maybe some detail on the kit used, how it is fitted, other upgrades done to allow the turbo. Anything other than a couple of random pictures.

the video posted at the in the beginning was the car running a 2 step set up with like 8 psi. thats why it sounded like it did.
some parts info:

• Stock 4.2 RS4 motor

• borg warner efr9180 turbo

• no kit used, all custom mounting

• haltech stand alone management

First 4.2 rs4 swap in a b5, first single turbo rs4, and just might be the most proven power at 9 psi.

lol im not sure the difference on rules in the US but i think we only have a visual inspection where this car is

Looks incredible mate. Would love to see a bolt on sensibily priced kit for the B7 though, rear mount seems to be the way to go

this is my brother's Shop build, and i've got a rs4 that i want to do this to, although i probably wont spring for the standalone management at first. i want to help him develop a kit. i'll def start a log once we get to the motor work.

It’s all very well! BUT, I am having troubles believing it did 750awhp at 9psi... I mean can we see some logs? Like fuel trim, MAF, air temp, oil temp etc.

almost the whole dyno session was live streamed, i'll try and work up a video to combine it all.

That is a big bastard inlet pipe from the air filter to turbo

+1 to this. Show us the science!
Are the internals stock bns items? No sleeves or low comp? I know you can push these engines hard and that the FSI is the real limitation.
