Let's say hypothetically that the pics below were BOVs. Which one do you think is better looking A or B?

B

(Even though I think they both look terrible. I'm a fan of the Tial style).

Finland

looks like an HKS copycat, but I'd pick A if I had to.

White Smoke

Why does everyone always have to hate

I personally like the B style myself. Good luck with the design

Will this be made sorta like the "RS" BOV from ATP? Anti-Stall???

A, because B would cost more to make.

simple things that Work, always look good.

i would say B , A looks too much like the hks ssqv design

Synapse interesting they both look nice but I know you strive to out perform the regular , but tell me how it exceeds other valves and I'll wait for it to make a release date.

Also please tell me more about your wastegate, I'd love that too based off the same inner workings of your synchronic, I'd move on to it.

I sent a couple emails no one returned them ?

Synapse

Interesting feedback results. The internals are the same with both. I think aesthetics are the hardest to figure out, which is why I was looking to see what your guy's thoughts were. I was really trying to stay away from looking like what is out there because the technology inside is so different. But there's only so much you can do, too different and it alienates people and no one buys it. I'm done with the front end, Red section, the back end is what is giving me trouble.


Mid-This BOV has the same guts as the wastegate.

Some basic design features of what it can do:

1) Pull-type, but mathematically impossible to open under boost (except for pop-off mode)
2) Solid aluminum valve and actuator, no diaphragm
3) Inherently sequential by design without concentric valves, so low boost, lower flow. You can switch the valve out too and go non-sequential
4) Level of valve lift entirely dependent on boost pressure in the intercooler piping
5) The first BOV with a race and economy setting
a) Race- Valve always stays shut, even under cruising for faster spooling
b) Economy- Valve bypasses turbo under cruising to reduce intake restriction of turbo and maximize off-boost fuel economy. Kinda like how the JRSC blowers are setup
6) Dual action valve - works as a BOV and as a Pop-Off valve for overboost protection
7) It will have a straight weld-on flange that can keep the BOV very close and tight with the intercooler piping
8) Re-routable discharge for the mass airflow cars

Will the mouth have a screw on for a recirculation fitting for MAF cars? I need that.


Oh yeah and I pick B because I'd be able to hold it better and the less material means its lighter.

Thanks for the info, I love the engineering on little things like this.

MidShipCivic

Never mind the recirculation fitting question I just caught #8 .

Definitely a recirc fitting. And B is definitely lighter.

yee SERIOUS

That RS is a cool BOV design. I can't find though where they talk about what the anti-stall feature is all about. Do you know what it is supposed to do?

Its for MAF equipped cars that have a problem idling with the open atmosphere ventilation like the WRX. I'm not exactly sure how it works but I do know that its supposed to prevent the car from stalling out when you depress the clutch. You know how the RPM's drop rapidly and sometimes the car will come close to stalling. (MAF cars only) The WRX is one of the worst and most end up having to route it back into the intake. This BOV is supposed cure that issue for those that want open atmosphere discharge.

I dont have as bad of a problem in my 240 but sometimes when I rev it really high and push the clutch in the RPM's will drop lower then I would like. Without any BOV installed I have zero problems. I think where the BOV is mounted makes a big difference too.

i think "B" if they wer made out the same material it would probs be lighter in weight

Reading can save lives.

I donno i was looking at them a little more and altho there arent moe choices to choose from, the form of them kinda seem bland, and i understand the not wanting to alienate people with a crazy concept or design.. i just get a bland feeling from them. altho if the inter structure design is better than the outter structure design it would give it kind of a Sleeper design overall? if anyone gets that

Blanket Jackson

I like A.

Synapse

With MAF cars, the issue is that you are dumping out metered air that isn't coming back in, so you're slightly flooding the motor cause fuel is the same but less air, the timing advance and TPS doesn't coincide with the amount of system air volume impacting RPM. I think that the RS allows the primary valve to shut faster, so that you have a fixed volume of air that goes out and you don't have too much air discharged. Think of it like one of those revolving doors for hotels, only a given volume can go in and out per unit time.

I think I can do the same with a slight geometry change and possibly a different valve specifically for the WRX et al.

Thanks for the info.

A reminds me of a shift ****, and B reminds me of a large nut.

A

VI Boost

B imo

rkeith

Neither, to be honest. Be if I had to choose: A.

PS. Who cares that B is lighter than A? The weight difference would be so negligible, it'd be the same as farting before the race to shave your time.
