Forge 008 Diverter - Interest in group buy?

[noone]

Its not a blow off, although you can get ones that do a bit of that as well... If you'd prefer to spend a bit less, you're welcome to my Forge splitter when the 008 arrives. Works fine, but always interested in a new toy...

Basically as there does not appear to be any benefit to a group buy, I'm thinking we go through the TTStuff website. I've placed my order, I'll keep you posted as to the experience.

Ordered mine from TTStuff...

Would love to get local reviews, especially on holding boost and sound. Seems to be much smaller, as I did switch from 007 to R1 due to the 007 splitting the boost vacumn cable. Just my experience.

Kangfu, if you get this, you know what's up - lol

Mine arrived today from TTStuff. Over 3 weeks, but thats what you get with surface mail.

Its nicely packed, they've provided nice hose clamps, 3 springs, 3 shims, allen-key, even the cable tie for the vac line. Paint on the springs is a little crude, but obviously only to indicate which is which.

There is a little glossy booklet that goes through how to install it in detail, but nothing on how to tune it, which spring is which and how to set it. I've noticed Forge is quite careful not to make any promises or figures with these products which is smart, there are so many variables. If you say it will hold 20 PSI, you might get people ringing, wondering why there otherwise stock car does not boost to 20PSI now.






I'll have a play tomorrow, I could chuck the stock diverter back on to see / show any difference. Not really bothered, so let me know if that interests you.

[pog]

Yes, please do.

Please let us all know the difference between 007 & 008. Sound clip would be great!

Diverter works well. I don't know if i'm holding any more boost, but the unit works well. With my setup you can hear backing off the throttle from 2000rpm, the pod filter setup makes it quite audible.

The old (splitter) and the new (008 )


Started with the Yellow spring and 1 washer, seemed fine. Tried 3 washers, sound became quite whistly which I assume is the air struggling to move past the valve. I've backed off to 2 springs, which seems to be a compromise of both

From what I gather (reverse engineering), the role of the vacuum from the intake manifold plays a greater role than I had originally thought.

If you try to press the valve open, like the boost does, it takes a lot of effort. If you suck on the vacuum nipple (ha!) you can feel it open reasonably easily.

The sound of my Forge Splitter Valve and the 1 and 3 shim setups with the yellow spring in the 008 all sound a little different, this may sort of make some sense:
Splitter: coooooh
008 - 1 spring: cah
008 - 3 spring: tssew

make sense now?

All in all, its always nice to have a new toy. I'll reset my ECU sometime and go for a fun drive, see if I notice any difference in a harder driving environment. As the noise of each change is more distinct, I'm likely to go back to the stock airbox so I don't feel like cringing from the noise I now associate with an EVO more than WRX or Skyline. Not a massive difference, but just the mental association when I hear it. Its not THAT loud, but driving in suburbia, shifting at 2500 rpm, it does seem a little funny to have it 'tssew'ing at the passers by...

Million dollar question: would you say it's a better design and overall product in comparison to the 007?

[noone]

I don't have one... I've not seen one in action. I had the splitter, not the 007.

Logic says that it is a improved design, but there were lots of people happy with the 007.

My only comment on the 007, is if you have not changed the spring from the stock one, get yourselves the spring kit and see of that holds more boost.
