im starting to piece things together now and im debating on buying either the tial Q 50 mm BOV or the HKS...

can you guys give me some feed back as to which is the better more reliable BOV...

im only keeping in mind the HKS for recirculation purposes if i need to recirculate but prefer to keep my products all 1 based ( tial ) since my wg will be a tial..

thanks for any help..

also whats the difference in the regular tial BOV and the tial Q... thanks!!

 

synapses with anti stall kit is supposed to be sweet too.. consider that one as well.

 

no synapses!!! lol

 

Pete,

I'm glad you're putting things together.

I would stick with any BOV that will be able to recirculate back into the intake. It really doesn't matter if your BOV is brand X and your wastegate is brand Y - unless you're going after aesthetics.

The HKS SSQ can recirculate with an adapter, the Greddy Type S or RS works, TurboXS RFL, Forge, etc. The Tial doesn't I don't think unless it's tha Alpha Q.

Function over form I'd say..

 

I've stalled twice with my Greddy and a few times it had a hard time finding the idle again (bounced 2-3 times), which only happened after a good amount of pulls. Then I finally listened to everyone and shortened my vac line running to it and it seems to have smoothed out.

I'm with you on the no synapse thing though .

 

Carbon if you recirculate that BOV you will never stall out.

 

the hks and tials are the ones im sticking with unless i can find and old school blitz rs ( cuz i like the sounds lol )

im also with the hks or tial i can get them pretty cheap here locally... and i like keeping it all uniform but if i have to break for function then i dont care... im only asking as my friend is offering the tial Q for way below msrp .... and if it can out perform the hks then i'd rather use it.. i have a friend who uses his tial on his turbo tc and has no problems..

but i wanted other opinions on ppl using the tial bov.

 

The way I can see the Tial working without recirculating (well you can't on the Q), is to have the BOV after the turbo, before the throttle body, before the MAF. So this means the MAF has to be installed before the throttle body on the charge pipe.

There have been a few people that do this.. and it's not that bad. If you want to BOV into atmosphere, this is how I would do it.

 

That's how the PTuning kit will be.

 

you can mount the tial bov on the tube that goes to the TB.. my friend has it that way and has been great venting to atmosphere.. im contemplating another setup style where the bov mounts closer to the fmic. ill try and dig it up so u can see what im getting at..

if not then the HKS will just have to do or possibly the greddy rs.

 

What engine management?

 

I've tried four, all recirculated. The Greddy type S, the HKS, the raptor and the Synapse. Without any doubt at all, the synapse is the fastest to respond and the least ricey sounding. The HKS sounds horrible IMHO but would say it worked almost as good. They Type S worked ok and was very quiet. The Raptor has the same horrible sound as the HKS and doesn't work very well either.

So I recommend HKS or Synapse depending on which sound you like.

 

TiAL can work but requires some massaging into the tune for the car with the engine management used. I have successfully completed this with HKS and TiAL being non-recirculated on a turbo tC.

 

That's what I said

That's the charge pipe.

 

F/IC. It stopped doing it completely after I shorted the Vac line...and I was pretty rough on it this morning.

 

i also have heard alot of good things from this one

 

Ok. That or you can try adjusting the injector response time on the setup pane, and that will also stop this problem.

 

FOR THOSE WHO INQUIRE... i will be using an AEM FI/C for tuning.... my 600 whp gial lulz


thats a good bit of info though carbon.. ill make sure to keep my vac lines short... ill be using a vac block guaranteed...

also what papa paul suggested also is something my friend has done to fix the same issues... its just alot of tuning work to get it all dialed in.

 

How would you convert the Turbo XS RFL to recirculating? Replace the horn with an outlet hose adapter? I'll ned to check if the horn is even removeable. I've got a RFL that came with a used Greddy kit for the xB, I'd like to try a recirculating design instead.

It will need to be moved anyway from the existing charge pipe since I'm adding an intercooler, so the time is good for re-work.

 

I used to have the tial 50. lots of stalling issues. Switched to the synapse with anti-stall kit and i couldnt be happier, idle after boost is just as smooth as when it was non-turbo. sounds very good as well since the anti stall kit still allows you to vent to atmos.
