APR Tuned - 2.0 TSI & 2.0T FSI - DYNO GRAPHS - Comparisons Inside!

Looks like the new motor (2.0 TFSI) makes near identical power/torque as the old motor (FSI 2.0T), both stock and with APR software. All this really concludes is that the old motor was basically underated from the factory, and that the new motor has better power down low, but less up high (rpm wise).

That's the trend I've been seeing with Audi/VW and the 2.0 engine. The newest version is more diesel like than the previous one, and I for one think it's NOT a good idea.
Low RPM torque is gook, mainly for city driving.
But, I like high rpm torque for performance driving, and those graphs don't speak well for the new engine.
It SERIOUSLY lack on the top end. That's how they are getting some of the improved MPG: less revs, less friction, less power up top, better MPG.

The software bumps and smooths things a bit, however, compared to the FSI the TSI only improves the low rpm curve a bit. It's less power, but it's more linear down low, until it gets higher revs and then it's seriously drops.

The Audi version with variable valve lift should really help a lot. Too bad VW cut costs and thus cut performance on the new TSI. Looking at those graphs the TSI really does need better breathing at high revs, and better valve control would help that.
It's also possible that the intake is quite restricted on the new engine, and simply can't breathe as easily when revs climb.

It would be cool to see a better intake flow and it's numbers and graphs.

Good info on the dyno's.

Per the first graph (stock/stock) the T FSI engine tends to have a slightly more linear power curve which is great for a turbo car (or any car for that matter but hard to get in an exhaust driven/forced induction app). The power drop does not occur till late in the graph (over 5k). Not too many folks are driving in that range often anyways.

From the thousands of motorcycle dyno runs my company has done we have always found that the bike with a linear power curve and a peak of 110hp (rainbow graph) will always beat the bike with 135hp peak and a spiked power curve (mtn peak graph). Of course this being on the same motorcycle. By the time the "spike graph" bike has reached its maxium hp out put the "rainbow graph" bike is long gone due to the power made all the way through the rpm range.

I am assuming this is what Audi/Vw engineers are looking for; linear power? Who wouldn't be?
