does someone have a dinosheet before and after?

greetings

A dyno is a single gear WOT run. I do not believe that these valves should not affect the horsepower or torque curve on a dyno sheet.

mmmh so there is no gain in this?

just wondering as of the benefit of the valve holds the pressure better so there is no gain then? so then I maybe should keep the stock ones or is there something I understand wrong

I didn't say there was no gain. I said that the dyno curve should not change. The benefits of this device would probably be best seen with a a datalog of the boost threshold as you shift between gears.

ah so you only get a benefit on accelerating when you change gears then, did you install them on your car? so far i did not find anything here in germany

I'll let Dan answer these questions, as he can give you the specifics about his version of this modification.

cool thanks as I am starting to upgrade my GT2 so I would be happy to get some feedback about what makes it a better car

If boost tapers off, you would lose that top RPM power. Also if boost is slow to respond, you would have a slower bottom torque curve. Would you see this on a dyno, maybe. Would you notice the improvements driving, absolutely.

good info thanks guys
