Honestly, Cumminsredneck, I don't know how you could stand to put up with that childish banter on that website. That kind of talk is just plain stupid and makes the people on that website seem foolish. I could barely get through that entire thread without steam coming out my ears. I guess that is why I don't subject myself to that sort of thing. I am not the least bit interested in participating in that sort of thing.
I am more impressed with this website than ever before. It is full of fantastic and helpful people that love to have great conversations about the trucks we love WITHOUT putting anybody down, even if they don't share the same opinions. It is these differing opinions that I think make for some great conversations and debate.
Thanks to all the members and especially the moderators for making this website great!

Well in theory you could use a BOV or a relief valve of some sort to help with compressor surge but if you're careful with that then a BOV on a diesel is a complete waste of money. I have no idea how you'd hook it up, must be special ones for diesels?! I have heard of it before just not of very many.

Ok, let me get this straight- A blow off valve goes on the intake side, and is actuated electronically, not mechanically? So on these little ricers do they have a button on the clutch, or what?

I had a BOV on my old truck.
I had drag raced my old 2000 24v with an HX40 for 3 years. The first 2 years, the turbo barked badly on every single shift, but never blew. I knew It wouldn't hold up another season of racing so I had bought BD's blow off valve, and it worked fine.
It workes different than gassers...it uses boost pressure to hold the valve closed, then when you jumped off the throttle, the microswitch opens the solenoid, venting the valve, and your boost pressure on the other side pushes the valve open.

That sounds like an expensive BOV.
Most ricers are turbo want to bes, so they get some electric thing that sounds like a BOV going off.
Yes I'd think if you had a fast solenoid you could put a switch on the accelerator so it is only hit with the driver's foot off the pedal. Then it could send vacuum to the normal BOV and I'd think it would be cheaper. But a BOV that hits this high of pressure without leaking is going to come at a price.

That's why I don't think one that works off vacuum would be of any good on our diesels. With my HX40 it had to hold 40psi without leaking. So I do believe you will need one that equalizes pressure on both sides of the valve to hold it closed so it doesn't leak. BD's does and it works.
I don't remember what I paid for the BD unit a year and a half ago...something like $400 bucks or so.

most quality aftermarket BOV's show boost to both sides of the diaphragm... so you have 40psi of boost pushing back against the 40psi in the pipe. then, when you let off, vac is applied to the top side of the diaphragm, and the BOV releases instantly.

"the reason diesels don't run BOV's is because they don't have a throttle body and they never make any manifold vacuum...OWNED!"
Cumminsrednecks repsonse back on his forum. Too bad he didn't actually learn anything =P They were actually asking about making the turbo whistle, so instead of learning how this is done he finds a quote to "own" with? Nice.
