BOV on VW Turbo Diesel???
 

Can it be done without hurting anything?

Re: BOV on VW Turbo Diesel???
 

Does the Engine have a throttle body? Most diesels don't have a throttle body and instead work by throttling the amount of fuel being burned. If it doesn't have a throttle body theres no point in putting a BOV on one because it will never open.

someone posted awhile back that its pretty much pointless to put a bov on a diesel engine, it was linked to vwvortex.com

oh my god, you want to be the biggest ricer ever go ahead and put a BOV on a car with no TB

An exhaust brake would be cooler... marginally.

LOL

actually, one that was driven from teh alternator vac pump and controlled by a tps switch on the gas pedal with a solenoid could be useful to keep the turbo semi spooled on a shift... i think, but maybe not.

u all forgot about the maf sensor

is this some modern POS ecu controlled diesel, or a reliable injector pumped diesel (which was the majority, and should stay that way for diesels intended purpose of pulling heavy ---- around, particularly partly under water.) if the latter, it doesnt have one, if the former, the man has a point, and it would be best to leave it alone.

no ----, you can't blow off metered air to atmosphere without making the car run like ----. not only that, but does a diesel motor even produce enough vacuum to actuate a BOV?

Re: BOV on VW Turbo Diesel???
 

it does... from the brake vacuum pump on the alternator (thats where it usually lives) and most existing diesel engines dont have an ecu...

they dont have any spark plugs either ;-)

Re: BOV on VW Turbo Diesel???
 

You don't need a BOV on a diesel. Period. It will do nothing but sitt there on the pipe closed. Diesels can't sure because there is no Throttle body. The work though metering the fuel, not the air.

Re: BOV on VW Turbo Diesel???
 

if you had a tps and a box that could read it, it could electrically trigger a vacuum solenoid driven from the alternator brake booster vacuum pump, and pull open the valve on lift off. this could help the turbo from slowing down too quickly... sure, its not needed, but it could help with any lag somewhat...

provided it is an engine with an injector pump on it.

i'm not saying that i'd bother, or that its worth it, but it could be done, and could have a benefit.
