2.5" swingvalve

[slasky]

I currently have a 2.25" swingvalve going into a 2.5" downpipe and exhaust in my charger. I know it would have more power with the 2.5 swingvalve but how much?

It should be good for 10hp I guess then on mine. I could always just bump the boost up 1 psi instead of swapping it. I guess i will see how easy it comes off.

No, The boost bump will not help. You've reached a "bottleneck"

19 psi with a good s/v set-up (I ran a Diago 2.5" hogged to 3" and a 3" downpipe) Has been prooven by 2 people to max a stock turbo out at about 109+ mph. There is just NO more left in the hairdryer at that point unless you go front mount.. then an extra 1mph is about it.

I am trapping at 105 now. What et would 109 get me? So even if I unhook my vac line from the waste gate and run all of my boost, I would not see a trap speed higher than 109?
