I just receved a second hand Forge BOV and installed it today. It came with all the springs and shims. My stock BOV was doing fine, but I am going to go with a bigger turbo soon, so I picked one up off this site (for a very good deal). When I opened the package I was surprised by the size and quality of the piece. So, I decided to use the yellow spring for an initial run and I am glad I did. The Forge worked just like stock. No surge or any weird sounds. I run the stock air box, w/ stock filter, BOV recirculated, and you can still hear, what can only be described as a muffled whoosh sound. Also, it seems like the boost comes on faster and harder w/ it. I run about 23psi tapering to about 19psi and the yellow spring seems to hold very well.

All in all, I am happy. Just thought I would share.

 

Yes I never have had any problems with mine either... However, many people have not had such luck.

 

i have a VTA on mine, works fine, and never stalls and i run 21-22 psi

 

FORGE bov has never let us down. The recirc. works great, and the 100% atmo-dump sounds great and affects the idle slightly, as compared to HKS (stalls). TurboSmart dual stage works like a charm as well on the Evo.

 

I have had great luck with mine I had the rec type with the stock turbo great sound to.

 

We really appreciate your kind review of the product!

I'm am enthuzed to hear that you are happy with the valve and that you have had success with it thus far, though, I will concede that some customers have experienced some hesitation with the Recirc. valve in some instances. We have even duplicated the occurance on our own Evo, but we should soon have a solution to the problem that some customer's have had.

Those of you who have not had any problems should not worry.

We are trying to incorporate the dual-piston design and function of our Atmospheric valve into the body of the Recirc. valve to mimic the operating characteristics of the OEM valve design while still offering the full range of adjustability and serviceability.

We feel that this may take care of most of the hesitation problems that a few people have experienced.

We will also soon be releasing and All-New valve design which will be available for the Evo.

I'll keep you all up to date!

 

Mike, Evo BOV hesitation is just the nature of the beast in my opinion.

We have installed, seen, and played with (almost) every single recirc / atmo / dual BOV on the market available for the Evo. As soon as you step away from the stock BOV you are almost garaunteed that your car will not act the same. It will work great - but its just not the same as stock. That's just something you have to deal with.

I've actually seen MR BOV's act up on NON-MR Evos as well.

 

I'm pretty aware of this as well as I have recently been tinkering with a few cars, and doing loads of research, but what we're after is creating a valve that won't create any of these problems, regardless.

We are still not 100% sure that it will work as intended but we're hoping for the best.

I currently have 2 cars testing them out and I have only received positive feedback thus far.

It's obvious that there is starting to be and extensive market saturation of valves, but I think our products speak for themselves in their innovation and design features. These new valves will be no exception.

 

Are you talking about hesitation on VTA cars? My car has experienced no driveability issues.

 

I would like to purchase a new bov for my car but I have in the past and feel like I have wasted over $500 trying to do this. I first went with Hks ssq VTA, that was a HUGE mistake. Car ran great until I got on the interstate. When I would give it just a hair of gas and let off "just to keep steady speed," the car would jitter and jolt real hard. I tried adjusting screw, no luck. So after I spent 300 on that valve, i spent another 30 on recir kit. LOL, car ran 20x better in VTA mode. The jittering and jolting became much worse. Finally sold that on here and purchased a bitz go fast so I could have some sound. That stayed on my car for about a total of 30 min before I sold it on here. Put my stocker back on and it feels like a totally different car. I know this may sound like BS, but I have tried it with 2 evos now to be for sure. I do not know how it affects this, but a 7k shift is SOOO much easier with the stock valve in. I guess its the extra fuel burning when you left off gas to shift and it not recir correctly. I have been looking into an MR valve, but its hard as **** to find them. If you order from mitsu dealer, its a plain plastic one. I pressure checked my stock valve and it does not hold boost steady after 18psi so I do need to get a different one, but want something that i know is going to work. I might try the forge but have too hear alot of people say it works fine on the car before I spend more money.

 

Glad to hear that there are some of you out there who are having a good experience with forge bov, some of you are even running boost in the 20's. I had one for a while but when I got to the 21-23 psi, my unit disintegrated and I had to switch to another brand 'cuz the forge unit kept losing boost due to loose screws.

 

For JJ, I'm actually refering to the hesitation on Recirc. valves, not VTA valves. Many cars have experience severe hesitation and drivability concerns with the use of an aftermarket recirc. valve that is not 3-chambered like the OEM valve. One of the biggest problems is the complexity in the design of the OEM valve and the difficulty in designing an aftermarket counterpart with the same structure and operation.

For an0ther, we are still in the testing phase on the design with the dual-pistons, so keep that in mind, but I just wanted to let everyone know that we are working on it. The all-new valve will be released in a few weeks and the new Evo-specific valve with the dual-pistons may be a few weeks after that.

For bluevo, I sincerely appologize for the issues that you had with our valve. It almost sounds like an isolated incident that we would have easily sent you a replacement valve for. All of our valve bodies are designed to withstand up to 50 PSI, with the adjustment with the springs allowing upwards of 30 PSI or so. I am not sure where the problems you had would have come from. Again, I appologize.

 

i have the forge blow off valve no problems

 

There is a very interesting write-up in the DIY section about "modding" the stock BOV by adding a few screws so it'll hold boost better... Even if it's something you'd never consider (I certainly am) - it's an interesting idea - akin to the "crush" mod from the 1g BOV's.

Two of my buds here in FL have the HKS SSQV, love it and have no driveability issues.... but I've seen dozens of people post on here that they hated the HKS.

Ditto the Forged - these cars are damned finicky, it seems.

I don't think this even qualifies as .02, but I thought I'd mention it - if nothing else, to maybe steer people toward the DIY forum - lots of good info in there.

Cheers.

 

The only time my Forge valve causes problems is at highway speeds when I am in the throttle and let off slowly.....the car jitters and bucks a bit. I have the yellow spring in the valve, and my boost is rock steady at 21 psi. There is no problem if I let off the throttle quickly.

Mike@Forge....what are your thoughts on this????
