Turbo 1 BOV, how to install?

[Philpot]

I have a 85 shelby charger and want to install a bov. i know i dont need one on a pull thru type turbo setup, but is it possible to install one for the sound, and if so where would I install it?
thanks

welcome to the board!

also here is moreminfo on intercooling it if you haven't:

DDG- Intercooling the log manifold

if you just want the sound:

eBay Motors: SUNAMI FAKE TURBO SOUND SIMULATOR/ BLOW OFF VALVE NOISE (item 290138707339 end time Jul-15-07 09:53:08 PDT)


sorry I couldn't resist.


Oh and do you happen to have any charger parts for sale? I am looking for a front motor mount( the whole thing including bolts)

[Philpot]

I think I would have to pass on a fake one. But if I have to put a intercooler on i may go that route.
Sorry no parts, I need a hood, Mine is bent. thanks

Anyone know how to install a BOV on a turbo 1 motor?

Welcome to the board. This post is a little wordy, but please read it and then maybe you'll understand why not only do you not need a blow off valve, but also why it won't even work on your car.

Blow off valves are to relieve pressure from the output of the turbo when the throttle plate is shut (like when you shift gears and let off the gas when in boost). On later non-log type turbo motors (1988 and up), the throttle plate closing causes all of the boost pressure in the piping between the turbo and throttle body to have no where to go. So it gets forced back towards the turbo (sort of). This causes the turbo to want to slam to a screeching halt and then spin backwards! This kills the bearings and seals and really shortens the life of the turbo.

Now, on an early T1 with a log intake like you've got, it's a completely different setup. The throttle plate is actually before the turbo. This means that instead of the turbo sucking in fresh air and compressing it and forcing it through piping to the throttle body like the 1988 and later motors, your turbo actually sucks the air through the throttle body and then compresses the air and forces it directly into the engine. So when you let off the gas and the throttle plate closes on your car, all that happens is the turbo can't suck in any air. All the pressure that the blow off valve would be used to release is on the output side of the turbo and gets sucked right into the engine.

Long story short, not only do you not need a blow off valve, if you installed one on your motor, it wouldn't make the sound you're looking for anyway! There's never any built up pressure for it to "blow off".

I understand what you are saying and after looking at it for awhile I see what you mean. Is it the same for adding a intercooler?

thanks for the reply.

nope, by all means add an intercooler.

Thanks for the info, Also since the post I have decided to pull the whole motor out and rebuild it., but I have never pulled out a 5 spd. Do I just unbolt the trans from the block and pull it out or should I pull it both out? I just want what ius easiest to get motor out. I have everything else off at this point but the trans to engine bolts and motor mounts, I am afraid to just unbolt the trans afraid I will mess it up. What is my next step to get the motor out? just unbolt the trans? Thanks for the info

Just unbolt it.

while the motor is out, look into buying a late t1 or t2 intake setup and convert it to
1. have an easier time intercooling
2. be able to install bov
3. make more power
4.others can add I'm sure
Do look in the engine intake section for intercooling ideas.

+1 on that! It's a great modification to do with the early TI's. It opens you up a whole new door for performance and parts.

I've got the intake and exhaust manifolds you would need to convert to a T2 setup. Intake has a fuel rail and throttle body as well Let me know if you're interested.
