the forge valve is kind of annoying. if I had an extra 200 bucks int he bank that I didn't know what to do with, I'd get the synapse for the heck of it.

lol thats the spirit (boobs)

Sorry for my ignorance.....but what's "IMO"? So the Forge is a better fit (pressumably an easier install) and half the price ($159 on mazdaspeedstore.com) with very similar performance increases over stock. Thanks for your candor, perhaps I'll avoid the hype and try the Forge.

The Forge is known not to hold as much boost as the HKS or the Synapse valve due to their design; push vs. pull.

Forge is a great valve if you are on a tight budget...but the convenience of the HKS and synapse are well worth the extra $$$; no messing around with shims, springs, or adjustments.

Just my 0.02 cents...

To be fair I did have to spend a few min tuning my Synapse to get the performance i was looking for ....

Hmm... OK then, my HKS was simply bolt-on and go... (lol2)

I hear thats a good valve!

The synapse is supposed to be a bolt and go too, but i didnt feel like it was as fast reacting as it was supposed to be so i took some pre-load(drivers sugestion) off and BIG difference it took like 3 min lol ....

I really like the idea of a quick and easy install/un-install incase I want or need to go back to stock. I'd really rather not have to cut the .8 inches off the rec house for that reason. Anyone else have an opinion on the HKS vs. the Forge?

BTW....at a $30 price difference (essentially the same price as far as I'm concerned)........performace and ease of install would be the two most important factors.

$30 between which 2

For the speed 3 in the stock flange location you do not need to trim the recirc tube(i know they say so but its works with out doing it) ...remember if you have the Cobb SRI you will need that .8 they tell you to trim..

This is based on having a cold air intake? Also, do you have to rotate the recirc tube to make it fit?

Between the HKS and the Forge. BTW......did you experience driveability issues with the Forge?

Their install is biased on the CAI I spoke with them 2x this week about fitment with the SRI I sent them like 10 pics.... What has to happen for the SRI users is you have the orientate the Synapse valve at the same angle as the stock to get the recirc tube to snake to the valve, what happens in the case of the Cobb SRI is that there coupler blocks the path that the recirc tube has to travel to get the recirc tube on the synapse recirc flange the "way" that they want you to angle the valve ..

Here is the way that Synapse wants you to orientate it

This is the problem you run into!

Here is the way the valve has to sit **IF your using the stock location(meaning you don't have a FMIC) to clear the Cobb SRI

If you notice dirvers pics he has the FMIC which moves the mounting location

plus the CAI

Nothing major ....With the forge IMO your either hard on boost or in vac it doesent like inbetween unless your running a soft spring(negating the upgrade) but that is what happends when you improve performance... Ill say again I liked the forge!

really want to get an opinion on the turbo xs seems like a good buy. I don't really understand the hybrid concept though? But can anyone enlighten me.

the hybrid recirculates (like stock) 50% of the blow off air and vents the other 50% to the atmosphere...

I hear you could still get drivability issues with hybrids...

Turbo XS also has a fully recir BPV designed as a stock replacement (so it claims).......$197

I'd consider that as an option......

Is there any fitment problem (like cutting the recirc hose) with CP-E CAI with synapse BOV?

the CPe works perfectly with the stock setup, so I would assume that if cutting is required with stock parts, it will be with the CPe intake.

SPEED305 · Apr 17, 2008

so i just got it in the mail.
this thing does feel solid!!
quick question tho, I saw the stock bov, and it sure doesnt look like I can just take the old one off and put the new one. am I missing something?

If it were me i wouldnt even cut the recirc hose i would just go buy a peice of hose the same size couldnt be more then $4 and fit that instead ..... this way going back to stock is that much easyier
