what one should i put on a 1994 dodge cummins stock turbo but got injectors and other fuel mods. will this bring down my EGTs and raise the boost to 35psi

Don,

I take it that your vehicle runs on diesel fuel? If that is the case, then the BOV will not work on your vehicle without a controller.

why does a diesel truck need a controller for a BOV?

Brian,

Diesel engines do not have throttle bodies so they do not generate vacuum to actuate the BOV, hence they require a controller to control pressure to the BOV to get it to open when back off.

Hey.

if i was to get the universal dual port, how do i tell which outlet size i need? its going to be fitted on a MY04 Forester XT

Will,

You will need a 32mm outlet on your Universal Dual Port

I am looking to upgrade my BOV to fit to my jetski. Using HKS BOV, but not happy with it. At present I am running 17lb boost, but will take it up to 20lb. Running a Garrett GT28 Turbo & are have 320HP at the prop.

The ski is used for closed course racing, where I am on & off the throttle constantly.

Have 2.5 inch piping from turbo & intercooler.

What BOV would you recommend

Thanks

Pat,

A 38mm Plumb back would be good for your engine.

what BOV would be good for a 1989 chrysler/dodge daytona Turbocharged 2.2 Liter Intercooled 174hp 4cyl ?

John,

Any of our 25mm kompact series BOVs will be fine on your car.

I am using a turbosmart v-port blow off valve. I have it turned down to the softest setting and it is still not opening at idle. I am also getting compressor surge as well.
There is a proper vacuum source as well going from the intake manifold to the top of the blow off valve.
Any suggestions?

Vasiliy,

Is it the new or old Vee Port. What engine is it on? The BOV is not suppose to be open at idle unless it is in a supercharger application in which you will need to use one of our soft springs to get it to be open at idle.

It is the first generation of the Vee port ( not the current model ) and it is equipped on a vq35 (350z). My biggest concern is the compressor surge that I am getting with the bov cap at the softest setting. However the bov valve does open and close.

Vasiliy,

The BOV should have a brown spring inside it which is our hard spring. You can use our yellow dual port spring (TS-0205-3101) to eliminate the compressor surge.

hey would the type 1 v port bov be suitable for a xr6 turbo ? its pretty much stock

Alex,

Yes, the type 1 Vee port will work fine your the XR6 Turbo

hey the type 1 bov works but there is a seperate soft flutter noise comin from the turbo at high boost when the throttle is let off. it happens a split sencond just before the blowoff valve releases. is the spring set to hard and not letting enough pressure out? thanks

hi can i get a bov for my 1997 1.9tdi passat and fitting kit and how much will they be could u get back to me asap please thanks

Alex,

Try reducing the spring force by backing off the cap.

Shane,

Diesel engines require a BOV controller to make a BOV work correctly. Unfortunately we do not have such a controller as yet.

gday, my name is Blake morris, i have recently fitted a bigger intercooler and plenum on my xr6 turbo, at the same time i fitted a turbosmart Kompact 25mm plumback bov (latest model) and even though i cannot really “boost” it due to the possibility it may lean out, when i back off all i can hear seems to be compressor surge and flutter.

my question is should it be more of a pssssch? is the bov adjustable?

cheers Blake

Blake,

It sounds like you might have installed the valve backwards or that the vacuum signal to the BOV is weak. Our BOV is installed the opposite way to how the standard Bosch valve is installed on the vehicle. Please confirm the orientation of the BOV.

gday, blake again.

i have installed the blow off valve correctly (i was aware of the opposite orientation).
i will reinspect the vacuum line to it.

i noticed that the bov vacuum line is on a banjo fitting. does the direction of the fitting matter?

cheers blake

Blake,

No, the direction does not matter

gday,

i inspected the bov vacuum line and found it was squashed from where i cable tied it against the ac line, thanks for your advice i wouldnt of picked up on it otherwise.

cheers blake

Looking to fit a bleed off valve to my 92 gmc typhoon. Suppose to run at 14.7 psi but getting over boost from new de-cat exhaust can I manually set your valves to a specific value and if so Which bleed off valve is best.

Deano,

Boost controllers will not be able to reduce the standard pressure that the wastegates on the car are rated to. Is the car standard apart from the exhaust system? Is there a standard solenoid controlling the wastegate or is there a direct line from the compressor cover to the wastegate actuator?

Looking for a bov to suit a heavily modified rb25det with 600rwhp and running 25psi boost. Will also be going to larger turbo and higher boost in the future, so at least be rated to 30psi please.

Thanks

PHT33,

Our Race Port would be ideal for a vehicle like yours.

Hi Sir,

Any BOV that you can suggest for a 2.0 4G63 with GT3076R turbo, facing compressor surge at certain RPM. Currently using HKS Racing BOV, seems not a good match……

Yee,

Our 38mm Dual Port will suit your engine and turbo combination.

Hello

I have a Turbosmart Supersonic BOV on my 02 Impreza STI. I recently got my car remapped to 1.57 bar boost and the dump valve will not stay closed on its hardest setting under full acceleration.

Do you sell harder springs to keep it shut?

Thanks

Connor,

For the valve to be push under boost, it must mean either there is a very large pressure drop between the intercooler or that there is something wrong with the signal to the BOV. We do sell harder springs but we do not believe that will solve the issue.

Has it only started happening after the tune? How old is the BOV? Has it been cleaned before? Is it mounted on the standard intercooler or have you got an aftermarket one? Where is the vacuum source from?

Hi,
I’ve got an SR20DET and i’m already running an older Type 2 Vee Port bov, i want to now also get a plumb back (the 38mm) and want to be able to change from one to the other when I feel like it. The Vee Port uses the older 3 grub screw set-up and i’ve noticed the new Plumb Back uses the clamp system. Will the clamp system still work with the 38mm straight pipe that I have the Vee Port mounted on to?
Thanks

Ben,

We have a adapter that converts the new clamp system to the old grub screw setup. The part number is TS-0205-2010. This will allow you to change from both styles.

Hello,

I am looking at getting one of your plumb back BOV to be used on a Mazda 13BT with upgrade turbo pushing 14 psi. What size outlet would you recommend I get ?

Thanks

Hello

Ive got a series 2 Ford Escort Rs Turbo (1990)

I really want to fit the megasonic as I would like to have it as loud as possible. I dont know of anyone who has fitted one to my model of car and ive read that most people fit twin piston dumpvalves as anything else will end up stalling the car, I want to break from the norm and fit the megasonic though.

With the megasonic being adjustable I can assume I can just alter it so it shouldnt make the car stall?

I currently run 14psi boost, would the megasonic be loud at this boost pressure?

Many Thanks
Andy

Danny,

A 38mm universal plumb back will be ideal

Andy,

Stalling the engine normally comes from the piston staying open for too long. Our valves can be adjusted to eliminate stalling by increasing the spring force to reduce closing time. What makes a BOV loud really depends on how much air your turbo is flowing at how much pressure but most importantly, the velocity of air flowing through the port of the valve. It might be best to get the dual port and try it in both megasonic and supersonic modes. You might find that for your turbocharger flow and pressure, the supersonic mode could be louder as the velocity of air escaping would be higher due to the smaller port area being open.

Hi, i have a t-smart supersonic bov with the flange, is it possible to remove the flange
and add a my98 fitting kit so that it fits my 1998 subaru sti? (and or) do i need some other adapter or clamp to do this?

thanks steve

Steve,

Is it the current style Supersonic? If so, then yes, you can remove the flange to fit it on your adapter kit by using our v-band clamp.

hey mate, what type of BOV would suit the 2jzgte

Dan,

It really depends on whether you want noise or not. Any of our universal BOV’s will fit with a bit of modification to the intercooler pipes. A Vee port would be the easiest to fit.

will ts-0205-2010 work with a race port or is the v band to small

Liam,

The Raceport has a much bigger v-band flange compared to the 38mm BOV adapter system.

So the race port will only work if you have alloy cooler piping

Hi there,i have an Fpv Fg F6 running 13.3 pounds of boost.In ur catalog u recommend using a Kompact series bov for the Fg xr6 turbo (who are running less boost) and there is actualy no suggestion under the Fpv Fg F6.To run the Kompact series in a Fg xr6 turbo u also need to change the spring as the one with wich it comes is too soft and the bov is open under idle.My question is should i go with a Kompact series and a hard spring or a Vee Port as i know these are a great unit?Thank you.

Liam,

We also have stainless steel weld on flanges (TS-0204-2001)

Chopster,

As a factory upgrade, for a car that isn’t going to be modified in the future or get the boost turned up, the Kompact series is fine. The Kompact plumb back is suppose to be open at idle and the Kompact dual port has an adjustable cap and shims to adjust the spring force so you won’t need to get another spring. If you are going to modify it later and run more boost, then running a Vee port will be much better, but to make that fit, you need to get one of our adapter kits (TS-0205-2058)
