Just installed the Synapsis BOV kit. I used the A & B ports Tee'd together to the vac source I used for my Forge RS DV. I ran C to the vac line running from the boost nipple on the j pipe to hallman ebc. Install was very easy. You've done one BOV ... you've done them all..

This might be one of the best mods I have ever made to my evo. It holds boost like crazy. No leaks... No flutter.... No bucking....
I can say with a straight face that this valve actually works better than stock. It behaves like a IX diverter valve in the city..but when you get into boost.. it just holds... This has to be the best BOV Ive ever driven with.

FYI... I have had HKS SSQV... Forge RS.... Tial.... IX diverter.... Viii diverter.

 

sweet just ordered mine cant wait to see how it performs with the fp red.....

 

Im using the forge rs, just wondering why you switched bov?

 

Most likely because of the part throttle bucking/flutter...

 

hmmm better than Tial?

 

I use the synapsis at 30 psi on the stock turbo with zero complaints from day one over a year ago now I bought it.

 

The Tial is VTA so it causes idle, and lift off issues on some cars...

 

nice, i picked up one of these myself. just for the record though, the name is synapse.

 

I switched from the Forge because of the part throttle flutter and bucking. The synapsis is very smooth and very quick to respond. The car feels stock except for the fact the synapsis holds like a race unit.

 

This.

I also have the Synapse BOV and like it so far. Install in the stock location is a tight fit, but it works really well and solved my leaky stock BOV issues.

 

what boost are you running ?

 

24 lbs without meth... 35 with meth

 

Sounds like you went thru quite few of them....

 

i'm going to have to try that, i hate the flutter with the forge unit i have

 

Ditto that.
