What blow off valves are you all using?

It seems like there is a big gap in price. JGS, Tial, Forge, Turbosmart-$$$$$

eBay knockoffs- $

Is there that big of a difference?

Some of the more costly ones are externally adjustable. My cheap ebay unit you have to take apart to change springs. I've read that different types make different sounds which is important to the tune kids. I just want the thing to open under high vacuum.

I have a cheap ebay unit on my Syclone, works fine. Paid like $28.00 It is externally adjustable. It was cheap & it works is all I can say.

Normally I do not buy cheap products,, just wanted to try it out.

Main thing to consider is, if you are going to run high boost, should look for a valve that is large enough to expel the extra pressure quickly & reliably.

Cant go wrong w/a name brand, but you need to make sure they are not knock offs. Do your research.

I use a turbonetics. Raptor.
