If he did a baseline and put down 270 stock on that particular dyno, then his gains are right on point.

Make sense?

The Test #'s are worthless unless you have a base from the same dyno.
If I read it correctly aren't all dynos on a 997S suppose to be similar around 300rwhp? 270rwhp for a 997S is very low don't you think, considering the factory quotes it at 355 at the crank? I'm just speculating. 318rwhp on a 997s with mods seems low considering you guys quote a 30-40hp upgrade from the factory with the whole exhaust system right?

But anyways he answered my curiousity by saying it is the PSE that is restricting everything.

Salespunk is infamous around these parts
The same car can have a variation of 10% on different dynos. Even on the same dyno there will be variation especially with humidity and temperature.

You missed my point entirely.

No, not all dyno's are going to read 300rwhp. In a perfect world, maybe.

No, I don't think 270 is low because I have seem some really wacky dyno figures and really wack dyno operators. Who knows how it was set up? Neither of us do.

This entire point is moot since he did not do a baseline run when the car is stock.

We are not comparing apples to apples.

Is anyone else with me on this one?
