Anyone have any info/experience with this Cargraphic kit?

Dyno chart seems somewhat "optimistic" showing 411 hp (302 Kw) and 317 ft-lb (429 Nm) at the wheels. My stock GT3 dyno'd 322 and 230 at the wheels, respectively, which equates to about a 15% drivetrain loss. So, Cargraphic is claiming 90 rwhp and 80 ft-lb from their kit.

I realize that the type of dyno they used could have a significant impact.

 

It's not 411 rwhp. It's 411 hp at crank...

 

Is Cargraphic not being honest about this? A dyno chart shows hp at the wheels and not the crank.

 

Usually tuners in Europe use crank hp and not wheel hp. Many tuners are using engine dynos so they get the right numbers (that's imho a good way...at least every car I've seen with high numbers on engine dyno is as fast as it should be in real life conditions...)

 

Duh!! Engine dyno. I'm so used to thinking of chassis dyno only, didn't even think of that. I've emailed Cargraphic to confirm. Thanks
