Installing Turbo without a BOV ?!

[ZEX]

hi guyz

i was wondering what will be damaged if i didn't include the BOV in the cycle ?

the engine will blow ?

or the Turbo will blow ?

BTW how much can i have a used one here in Bahrain ? << i donno anything about thier sizes and other specs :banghead:

and which garage is good in Repairing Turbos and sells used turbos ?

[NOS4EVER]

You have to give info on the car, engine, drag/street use?

[ZEX]

I just want to know the damage it may be done to the engine if there is no BOV

it's for street use

3.5 liters V6 engine << there is no ready turbo kit for it , custom turbo install

its still not installed , im collecting some info's , but if the bov is not imp. it will be fast because i asked for the price and they told me its 120BD for a BOV ?!!@! (they say because its ""RACING"" cheaters)

وايد أتحجى :D

المهم أبي أعرف يخرب التيربو أو المكينة ؟

the Pressure will be under 5 PSI for the beginning

No turbo system should be without a blow off valve, or a bypass valve that will circulate the air and keep the turbo spinning between shifts.

Its like having a fuel injection system without a regulator.

you keep your turbo healthy and extend its life by using a blow off valve. Not installing one, will cause the turbo to choke with the compressed air between shifts, because the throttle will be closed, and the air will have nowhere to go but build up in the pipes. And if it keeps doing so, u will stress the turbo shaft enough for it to snap.

Or if i would make it simple for u and i. Just simply install one :)

Dont listen to that "racing" bollocks they chuck at u. they assume ur a nooB and most ppl who go to garages dont really know alot about cars, so they can be scammed really easily.

Get a second hand BOV. www.e-bay.com dirt cheap, if you know how to bid :)

thnx ADM 4 the help

actually it will be a Remote Mounted Turbo "STS" , i thought that the long pipes will reduce the compression of the air between shifts

i will take a "Farra" fe salambad tommorow and check out if i find something worth its price

[Quarantine]

many turbo cars do not come with bov* from factory.
if you want a kit without a bov in the cycle, on the intercooler pipe that goes to the intake manifold, fix a recirc valve and hose before the throttle body, and the other end of the hose should connect to the intake pipe after MAF sensor.

Are you installing the kit from STS themselves? Or are u custom making it all by urself? If the kit itself doesnt have a BOV, that means it doesnt need to, because they have obviously done their calculations before deciding whether the system needs one or doesnt.

And what car is it going into?

its not clear , but it's okay for now , i asked a friend , he have a Seat Leon with DEV or something like it as a blow of valve , i will check if this will be right for my case

thnx

its custom , and there is too much work and problems with the fitting positions , such as the intercooler "my cars front bumper is tight" , too many things .

the car is TOP SECRET :D , its not a secret , but i will tell u after approving to setup , i don't want it to be something that is supposed to be Powerful but if failed because some :flame: things

tommorow i will post some pics (maybe turbo setup , or maybe the things that cancelled the project :( "as the mechanic said")

hope me a good luck :D

the engine will blow ? no

or the Turbo will blow ? yes

Compressor surge is bad for the turbo's bearings..... it will shorten the life of the turbo... but it wont make it useless.. u'll still get a few years outta the turbo.. (longer than the motor is probably gonna last in this case)

if it's a dual ball bearing turbo.. or has anti compressor surge technology.. you'll be fine

many guys in japan Run Bovless...

you actually get better boost response that way...


there are "racing" BOV's... they can dump larger volumes of air quickly.. and they have a very stiff spring so that they don't open prematurely under boost

but for your application.. a regular one will be fine... but don't get an OEM one

:up2:

Thnx ottoman 4 a cheap BOV , BTW i found one for a Mitsubishi Eclipse "stock turbo" but it will not do the job for my car

thnx Dragsters Team also

I had a problem today in a very bad time !

the engine cuts-off fuel at 2.5 - 3 RPM !!!!! i checked under the hood for any problem and then it was >>>>>

the crankcase breath hose << i think

it was cutten ! there is a copper part inside it ! how this will break ?!

--

BTW , there is a problem with turbo oilling , oil pump and programming a Mini-ecu to control pumping proccess << as the mechanic said (( honestly i think his experience is not enough ))

and the intercooler will be very small , im thinking of DEI intercooler Dioxide coolers ((ADEL ZAINAL if u have any idea about there stuff can u help me ? << isaw DEI decal on ur car :D ))

also the exhaust manifold should have a عازل to avoid intake hose from exhaust manifold heat


it will be more difficult than i thought ! :pat:

[ADM]

Ok, 1st of all. There is no problem using the leftover of the copper adapter, as long as its long enough for a tight clamp to go on it.

What car are you trying to tune? Give us some info so we can help you out more.

the hose will be replaced , or fixed no problem

the turbo is the problem :D

my car is Chrysler 300M and i think it is designed to make it impossible for FI

Of all the cars :duh: you picked the most crammed engine bay to exist to turbocharge? Good luck finding space for the piping. Isnt the 300M a high compression engine? And are you sure the pistons can handle it?

Ive worked on 300Ms at Zayani, not bad cars if u look after them. But many came in with cracked crankshafts or needed new blocks because of broken con-rods. Good luck bro :)

WTF ?!

cracked crankshaft?! need a new block ?!

i've just ruined the Gearbox before 3 monthes , now it is overalled

oh god i think i will keep it like this , maybe exhaust sys. only . anyway im already going to buy new car (( running away of problems))

thnx 4 the warning , and to be honest , u r right , 300M is like a blonde !

My brother, thats only the begining. At the expense of the customers, i have witnessed what an engine looks like on the inside when a valve stem snaps, and the valve falls into the cylinder. Lots of things go bad on those cars, and i really mean lots. Bent steering rods, axle shafts. Some guy drove into a bara7a, and cracked his crank case. Drove home, and the engine went dry, and he kept trying to rev more cuz he wasnt getting any power. It was aluminium alloy spaghetti inside the block. They quoted him 1400BD to get the job done.

So yea, dont mess with it. Because the repairs, will punch a really big hole into ur pocket. Even duplicate parts are expensive for it.

Turbocharge a Honda accord or an integra, and you will still have a 4 door car. Not to mention the amazing reliabilty of Honda.

Good luck :)

oooooh my god , now before i full throttle it , i will think 1000 times :D

thnx ADM (( i donno your name :))
