Noice. I particularly like the refit of the original valve body.

Oui, mais ca, c'est un choix que seulement D_Hall peut prendre.

You'll almos certainly be down on power, and you definitely won't meet emissions regs, but if it's only the egcv you're probably OK. If you can, find a way of forcing it fully open.

Very nice. I'm half tempted to get one myself

The basic ones seem to be remarkably inexpensive and accessible these days, and I would think someone of your aptitude would find it useful for "lost wax" style casting.

La la la la la I can't hear you.

Hah, that's awesomely awful. Bravo!

Bollocks. Dewey put them out in the hope that, and I quote some of you can make use of these! There's absolutely nothing wrong with using them, especially if you give proper attribution if you eventually publish them. They were made public, with the above commentary. If it's for your own use, and yo...

Cobblers. And if you don't understand what that means, check it in a cockney rhyming slang dictionary. You don't arf push some pony out yer gary, geezer. If it's for your own use, just take the model and modify it. If you're going to publish it, either post it in this thread with attribution, or pub...

Dewey was last seen 11 years ago. Fix it yourself.

I think this is what you're looking for.

As D_Hall says, PVC is a bit sketchy*, and (as with all pipes), pressure rating goes down as diameter goes up. Schedule 80 is better than 40, but it doesn't mean twice the pressure, you get maybe a third as much again. With a longer barrel, you're going to be exposing the pipe to more pressure, and ...

I'm not sure that the speed of sound is an overly useful measure. As I understand it, and I've probably totally misunderstood, even in a "conventional" firearm, the combustion is subsonic even though the actual projectile velocity can be at least supersonic; and that it's pressure and the time the p...

Believe me, you really don't want me to join.

Yeah, but they are pretty (read "very") expensive, especially in the sizes you're looking at. Expensive enough that it's maybe worth talking to a local machine shop.

How about piloting a QEV with a smaller solenoid? That should provide a useful boost in performance without having to build your own valve.
