hey all,

im assembling my kit to run a BOV next year, would like those of us who are running a BOV sucessfully on their car to post up mods directly relating to making the BOV run sucessfully. chime in if you feel im missing anything!

my mods are as follows:

ZZP intercooler
ZZP charge pipes with MAF relocate
ZZP MAF Relocate
HKS SSQV4 BOV
HAHN BOV Block plate
Treadstone Intake without MAF slot
Stock Ko4 turbo

**will be tuned for BOV**

other mods include: HAHN 3"exhaust and HAHN 3" catless dp
Gm stg1 sensors
intercetpors

+ a wack of suspension

please do no bash BOV's im looking for serious help/input here, ive read enough threads enriched with hating on the BOV's

thanks

Trifecta ecp tune = blow off valve with no problems

 

im assuming HP tuners can tune for a BoV right?

 

This

 

I run the Trifecta ecp tune but ya hptune can do it. It doesn't work quite as well but it works fine they will just tune for the maf relocate.

 

I hate to be negative but you guys are wasting a lot of money on a noise maker. I don't think I've met a person yet that doesn't regret spending money on a vta bov setup later on. As well as the fact that you do get a little better response recirculating the bov back to the intake. Not to mention the ricer status.

To each his own though. Just make sure you get a worth while bov. The ssqv is one of the more common ones to get a knock off. I really recommend the synapse synchronic. It's the best bov for any application, rice or not.

 

Honestly, I love mine. It's so much fun. Maby I love it so much because more than anything I want a gtr r34. I wish they were legal in the U.S. I'm a ricer at heart haha.

 

I'd recommend the turboxs bov. By far the loudest one and sounds amazing.

 

And are those mods you have or mods your getting? If you don't have it yet then I would say hold off on the intercooler. It doesn't do anything. It's pretty much just to replace the plastic endcaps. I'd say get the upper charge pipes with out the man relocate, k&n intake, treadstone block off plate, trifecta ecp tune(really great tune)and well pretty much any bov. I have a turboxs one that's my favorite and I got an hks one that's pretty nice. I got it from a friend cheap and I think it leaks because of the seal. But they both sound great. I would say either turboxs or the synapse one.

 

i have been running an HKS BOV on my car for like 2 1/2 years now, i used to have a Trifecta tune with MAF relocate but Vince could never get it dialed in, now im HPT'd on a 25psi E47 Term2 tune with a treadstone block off plate and MAF relocate and it runs awesome, no problems at all. i have the ZZP lower charge pipe as well

 

VTA is needed when going up in horsepower number only those who track their cars really benefit from the instant turbo response from it being recirculated. unless im completely worng i also read this on Tial website. i have a type Q myself and for my goal a recirculated one wouldn't help

 

what kind of piping do you run?

 

I'm a ricer I guess

 

mine is installed on hahn piping soon to be switched put for zzp piping, with MAF relocate. also have a treadstone blocc off plate.

 

HKS dosnt fit on zzp piping tho?>?

 

I'm pretty sure the 1000hp Veyron has recirculating BPVs. Most OEM type aftermarket upgrades made by aftermarket companies also use recirculation. Look at the APR Stage 3 upgrade for the TT RS. 600hp with a recirc BPV setup.

Can you provide some more info on that claim?

 

Mods are in my sig and as of now I don't run a tune and mine works 50/50 so It only goes off over 5 PSI. Not many people have been successful so i would recommend the tune as I have to get one anyways for my intake and down pipe. But it still works without one.

 

just need the flange and it will fit

 

BUT the purpose of the BOV is also to save the turbocharger from surging when lifting off the gas, then overstressing it when you get on it (open the throttle) again. What it does is to allow the high pressure which would be trapped when the throttle closes, to be released, instead of forced back into the compressor

Blowoff valve - Wikipedia, the free encyclopedia

 

A bov doesn't have anything to do with surge. I know how a bov works. I'm not saying don't use a bov, I'm saying spending money just to have one vent to atmosphere for the noise it makes is a waste of money and that you can get a little bit better response from recirculating it.

 

your info is completely wrong that is the whole point in a BOV, I even posted the link to my source of info on the BOV, i would love to read who find out who has u believing bov does not have anything to do with surge..not to argue but that statement is wrong.

 

Your source is Wikipedia. A really reliable source....

What do you think surge is? I'd like to know.

 

Why is this ANY different than changing a muffler?????? That does nothing except make noise, and thats a common practice by many. I love the sound of the stock BPV, BUT I am addicted to the sound of a HKS SSQV BOV, granted Id probably get sick of it in 6 months, if i get a ss/tc I will definitely run one for a while.

 

 

B/c that truly is a noise mod. It does nothing (measurable I would assume) to affect response or performance of the turbo.

I remember switching my old turbo Spec V to a VTA BOV setup. It cost me 12's (ran a 13.0 @108mph) b/c the between shift spool time went up considerably. With the K04, it may not be super noticable I'll admit but it is technically making the system work harder to replace the volume lost to the atmosphere. Super noticable on big turbo setups. Think its a coincidence Borg Warner made the EFRs available with recirc style BPVs? Not to mention that the MAF was designed for draw through and blowing air over it that can have contamination (oil blow by for instance) isn't exactly smart. Vince's ECP tune doesn't sound so good to me either. I'd like to see him do that on a high hp car...
