Thanks Lux
Yes, a dyno may not simulate real world driving conditions, but it does provide a reasonably accurate before/after report on whether there's any effect of a mod. The only variable factors I can see in between runs are :
1) Tires (not applicable since I'm using a Dynojet)
2) Octane fuel rating (I'm using the same all along)
3) Air temp -> Density (Similar temp year round and I added a fan to normalise the intake temp to about 40 deg C)
4) The dyno itself (which shouldn't be since it's just a week apart on the same dyno)
Do you guys think companies like TechArt relies on butt dyno to market their product? I'm sure hours have been spent on dyno to arrive at the product they're offering today.
And Fahrius, not offence but I think you're contradicting yourself. You seem happy with the Techart kit that came along with the car, complimenting how good it feels compared to the other Boxsters. But the next moment, you're "not convinced the EVO or anyone else can lay claim to a better understanding of what makes our sensual little beasts tick than the boys (or fraus, if you will) at Porsche do."
End of the day, I'm convinced not everything stock and engineered by Porsche is the best. Unfortunately, like it or not, there are people out there who subscribe to this. There are parts that can be improved upon. It's a matter of finding out the 'right' replacement that will gain bhp/torque.
