I heard Works was testing the new Forge diverter valve. What do you guys think? I'm considering getting one if it doesn't leak and is truely 100% OEM drivability.

 

I did some of the testing on my own EVO with the valve and was pleased with the overall design/functionality of the unit. The adjustment knob is more user-friendly than the previous shim/spring setup of the older design. It does add a little to the bulk of the unit, but a small price to pay. Driveability in both recirculating and VTA setups was excellent once adjusted properly. (I found that adjusting the valve to crack open at -13mmHg worked well vs. the stock -16mmHg.) The sound quality of the recirculating configuration was excellent--probably the best I've encountered. The VTA sound is a little hollow under little or no boost due to the dual spring design--again a small price to pay for the performance/streetability the unit provides. Forge did their homework on this one and I gave them an "A" for their end result.

 

Thanks for the kind review, Jamie!

 

So what is the major dif. between this an the spring and shim model?

 

Well, mainly that you can adjust with a knob the point at which the DV starts to open. Before you had to mess with opening the valve, changing the spring and/or inserting shim(s) and you still might not have it perfect. With this setup it's just a small twist one way or another.

 

where do you get one? I didn't see it on Forge's web site.-- Nevermind .. Sorry

 

BTW, there is a group buy for this BPV going right now:

Forge RS BPV group buy

 

Jamie, does Works sell the new RS valve? If so how much is it?

 

It's not an item we currently stock, but we can special order one if you're interested.

 

Thanks for the response. How much would it be and how long would it take to order?
