ACT hdss5 and stock flywheel. Dreading the install . I'm surprised the clutch went so fast with only 330hp. I do t beat on it and literally drive once a week.

How many miles? My stock clutch was doing fine at 22k miles (with 6k at 400+ WHP and 8k at 350WHP). After the motor swap and turning up the boost it started slipping and has been giving me issues since. It works fine around town pull rolling into WOT from a lower RPM causes it to slip. As long as I downshift it works fine. Going with a sprung puck disk next. That should hold (and make quick work of breaking my tranny).

Yikes. And it's slipping with 300HP? That's not good.

but if you buy the tranny once, it will take you to all the track days and back. your 5 speed might only take you there ha ha

The six speed will be better for road racing anyway. Go blow up the 5 speed at the drag strip with a 7k rpm launch, post a killer time( If it makes it to the end) and trailer her home to recieve her racing tranny

Yeah, but a 6 speed costs as much as 3 years of track days. Lol.

I like the gearing of the 5 speed too. It took a while to get use to it coming from a 6 speed. With the power you're putting down I'm sure the gears feel short though, mine do not.

Yeah. The more power I get, the more I like it. Right now I feel like it has plenty of pull well above 100mph. Nice for daily driving too.

I decided to try Plasti Dipping my Forge BPV tonight. It turned out pretty good. It looks nice now, but I really don't think the Plasti Dip will hold up to much mounting/remounting or opening of the valve. If you just paint it, mount it once, and never touch it, I think it will look OK, but if you have to take it on and off, or open it often, I don't think it will last. Anyways, here are the photos...

Yeah, that was the plan. I originally ordered a black one, but it came with the older o-ring style seal, so I had to swap it out for this one (I was on the stock TMIC at the time). When I swapped they only had the silver in stock. I've been wanting a black one ever since!

I'm probably going to end up with the Tial QR in black. How are you liking the Forge?

Thanks! The Forge sounds very, very similar to the stock BPV. It is a quiet valve for sure. Similar size/form factor as well.

I like the Forge. It is a simple design, that will hold as much boost as you can throw at it. My only concern is that it is apparently designed to be open at idle (I have tested and confirmed this). I think that just about all recirculating BPV's are designed this way, but I could be wrong. Being open at idle isn't necessarily a bad thing, I think it serves to eliminate compressor surge (flutter) on partial throttle lift off. But in my mind it means that it takes a split second longer to close and allow boost to build. I haven't done anything to confirm whether this is really a noticeable difference or not (probably isn't), but it "seems" better to be closed under vacuum.

Recently I've thought about trying out some other stuff. I actually put a GFB hybrid BOV on the other day. It is closed at idle and vents 50/50 recirculating and to atmosphere. It is much louder than the Forge. Unfortunately I was getting flutter during partial boost lift off no matter how I adjusted the spring. I'm told this isn't really a bad thing, but I don't really like it. I've gone back to the Forge now (after painting it). Nice and quiet, and no flutter. I think I might try the TurboXS 50/50 next.

All the Tial stuff looks really nice. The QR BOV looks pretty big though. And you need an adapter

http://www.ultimate-racing.com/Produ...-TIAL-BOV2.JPG

I also think the TurboSmart Hybrid looks very nice. The Tial and TurboSmart are a bit more expensive though. I'm going to try the TurboXS first, and then maybe the TurboSmart Kompact BPV next. Then possibly onto the more expensive ones. Hopefully I find something I like. I think it may just come down to the fact that you either get a valve that is open/leaking at idle OR a valve that has some flutter. It may be impossible to get what I want. I'm not sure though.

the idea of they synapse synchronic bov appeals to me, and you can get it with the subaru flange and recirc nozzle

A positive to the recirc DVs are open under almost all vacuum conditions to allow intake air to bypass the turbo. At this point nothing is pressurized so it aids in off boost driving since cooling the air is not needed.

Air is going to take the path of least resistance which is from the dv return line in the intake straight to the manifold when the dv is open. It's not leaking at idle there's nothing to leak with no pressure.

Paint job looks good. Did you talk to forge directly about getting the valve in black or a distributor?

Would you be interested if forge offered a dual port hybrid type vta/recirc valve, with a dual piston design that is closed under vacuum and only lifts to vent boost?

As much as I like plug and play parts, I also like to fiddle with things. The Synapse looks like it has a lot of adjust ability options. It might be fun to try out.

Very good point about an open valve at idle. For some reason I didn't consider that it would actually be injesting air during idle. So maybe it would be best to have a hybrid that keeps the recirculating portion open at idle, but keeps the VTA portion sealed until it blows off (I think some exist like this). It still seems like that sacrifices response though. For response it seems that completely sealed would be best.

When I got the valve, the WRX flanged version (diamond seal) was not out yet. When it came out, it was only silver so that's what I ended up with. RallySportDirect handled the swap. If Forge had a hybrid valve I would love to try it! Do you work for Forge?

No I don't work for them but I've worked with them in the past on a lot of things. I was working on design for a new hybrid type sti valve but it seems what I have thought out should be able to put into design onto the wrx valve as well. Give me a couple weeks I'll get back to ya.

Unfortunately the US director isn't to fond of EJ's. It was easy before to get things into swing since we had the same cars!
