With all of the hybrid and other turbo options, is the RS2 turbo still worth the money?
 

I want to get close to the max HP with stock internals, and I am wondering if I should go the RS2 route ($1400) or with one of the turbos offered by garret or Javad? What is the max that I can expect from a RS2 315 whp or so? Are the other makers as reliable? Has anyone had a failure from their hybrid? Has anyone had Javads RS2 comparible unit on a dyno? $1400 has me doing alot of thinking before I buy. For you guys running a RS2 setup, would you do it again or go a different route or stayed content with a MTM chip?

Thanks

Yes and no.
 

Marc S and I run the same the same set-up...almost. I have a stromung and RS2, he runs a stock exhaust and Javad. The chips are identical. We pulled almost the same numbers on the dyno last year. The RS2 is more money but is plug and play; what Marc is running requires some work to install but is cheaper.

That said, your question was highest horsepower on stock internals - using that criteria, I'd go something different that RS2 from Javad, but be prepared to accept more lag.

What numbers did you get on the dyno?

I just looked up the sheets earlier today.
 

Right around 280 at the wheels.

My setup at the time was RS2 turbo and exhaust manifold, Stromung with cat, Racetronics 37 lb/hr injectors, Samcos, FMIC.

37 lb/min at 4 BAR is equal to how many cc/min?

What level of driveline loss is usually attributed (factored) on these cars?

I've heard numbers all over the place, since everyone uses different numbers,
 

it using wheel HP is the most meaningful comparison.

Does anyone know what a stock S6 puts down at the wheels?

180ish

looks like you're gonna have to do your own math on that one - lol.
