Are Diverter Valves the same as Bypass Valves? If so, which are recommended? Thanks

MoBrazen

asking for the "best" bypass valves is like asking for the "best" chip.

Fluffhead

Thanks. I wasn't aksing for the best, just a recommendation. 8 ^ )

No problem, you'll still get the same results by asking for a reco.

saw that the Strat one doesn't exactly fit right. I just want a replacement that I won't have to do that much work to install.

Thanks

...some are larger (Forge) than others, and I believe there is some difficulty fitting the front engine cover (if you care about that) running the Forge valves.

In terms of service, the Forge valves require servicing. The Bailey valves do not. The 710N valves do not require servicing either, but this is just a better OEM piece. I'm not personally convinced that a rubber diaphram is the way to go running anything over stock boost (or even running stock boost).

Not sure about the Hyperboost valves. They appear to be similar to the Forge valves with some slight changes. Not sure if they require servicing like the Forge valves do.

So if you want a better OEM replacment, that is in fact, an OEM part. Get the 710N valves (Bosch).

If you want a valve that is aftermarket, that requires no servicing, get the Bailey valves.

If you want a valve that is aftermarket and requires servicing, get the Forge valves.

Not sure where the Hyperboost fit it, but they would be an option to either Forge or Bailey depending on whether or not they require servicing. My guess since they are similar to the Forge valves in design, they require servicing like the Forge valves do, but this is just a guess.

Thanks for all the info. You just made up my mind. Bailey 8 ^ )

The Hyperboost valves are very similar to the Forge valves (the damn nipple caps are interchangeable). The Hyperboost valves would require servicing just like Forge. I have 3 sets at home: GoFastBits Hybrid BOV's, Forge & Bosch 110's. Whichever one is in basically depends on how I'm feeling (unless I'm in a car show).

...is that the Forge valves (and I assume the Hyperboost valves) run an aluminum piston. The Bailey valves run a Nylatron piston.

Forge switched to an aluminum piston after the original pistons started melting (this goes WAY back in S4 forum days).

Bailey switched to Nylatron pistons probably over a year ago. Nylatron has a higher operating tempurature than they previous material (not sure what that was).

I've not heard/seen any Bailey's that have had melted pistons, so I'm not convinced that running Nylatron over Aluminum is any disadvantage.

But just so you have all the facts before you buy...

Last thing. Should I get this fixed right away? Or can I wait until the next time my car goes in?
