Sequential Turbos

The engine in the A3 2.0 TDI clubsport concept car reads very impressive indeed, but I was a bit concerned about the "spontaneous response" ensured by the variable geometry of the turbine’s blades. I might be slightly old-fashioned, but I prefer engines that go faster and slower when I tell them to, not as and when they want. Still, for those sorts of outputs I suppose I could be a bit more easy-going :)

We need to find the specifics of these mods J-man!

The drive train

The high-performance TDI under the bonnet of the Audi A3 TDI clubsport quattro is like nothing that has gone before it. From its displacement of just 1,968 cc, it summons up an output of 165 kW (224 hp). Torque – the true measure of effortless motoring ability – peaks at an exhilarating 450 Nm (331.90 lb-ft), which is on tap from just 1,750 rpm; in other words, the very bottom of the rev range. As for in-gear flexibility, the diesel model leaves its gasoline-powered rivals standing.

I thought about this the other day. I imagine the motors would be quite similiar.

At least it gives us a ceiling to aim for :)

The 2L audi info is very impressive. Some nice concepts in there. I would love any more info if anyone finds it.

As for the sequential turbo stuff, im sorry but in my opinion you would be throwing money down a hole. The VNT turbos are there to do the job of sequential turbos. The variable pitch of the vanes allow it to act like a small turbo at low flow but still deal with high flow like a big turbo.

I can understand why muller laughed. Sure, you could do it, but it would be expensive and the improvements would be minimal. If you want improvements i think you would much better off looking into upgraded fuel maps and boost control with the existing turbo, or a large VNT.

remember its simple.... more air+ more fuel = getupandgo :driver:
