I've searched and searched on this...

The two places i've found that are suggested to recirc. are the throttle body (how?) and the intake.
My intake has a fitting that i could use , but it is after the MAF. Since the MAF has already registered that air, it doesnt need to re-read it right? or does it need to be in front of it

I'll try and get some pictures up.
Thanks

 

you should recirculate it to the intake pipe after the Maf.

The Maf has already metered that air so thats the place to put it!

On my DSM thats where it goes, and i see no reason why it shouldnt go there on a 240

 

What charlie said. Somewhere between the throttle body and the MAF.

 

alright thanks guys, there's already a thing there for it, i just wanted to make sure

 

The purpose of the BOV is to relieve pressure between the compressor outlet and the throttle body when the throttle is closed. Recirculating designs are intended to keep the engine from "losing" air that's already been metered. So, with that in mind, the 'return' side of a recirculating BOV needs to be plumbed in down-stream of the MAF (since the air shouldn't be metered again) and up-stream of the compressor inlet.

Hooking it back in AFTER the turbocharger but before the throttle body means it won't do anything - both the inlet and outlet sides will be at the same pressure.

 

Wow....alot of misinformation here!

as PNG says above, the Recirc should fall between the MAF and the compressor inlet on your car. Anywhere else will not only be wrong, it will create the same charecteristics as an atmospheric dump would..

Pics below: You can see the my blow of valve on the right (Greddy Type S) and the clear recirc hose back into the intake pipe between the MAF and turbocharger

 

yup!! When I said Intake pipe, i meant the pipe that goes from the MAF to the turbo, im not sure what you 240 guys call that pipe.

 

I'm going to give you cool guys a sweet little nugget of gold us Starquester's used to do to utilize BOV's.

Place the MAF sensor between then TB and the compressor out-let from the turbo. Then place the BOV before the MAF sensor.

The procedure would act as follows:

Air compressed in the turbo

Air runs through system (normally containing a IC)

Air passes BY the BOV

Air passes through the MAF into the TB

When you let off the throttle the bov will release the compressed air BEFORE it is metered. This makes it easy to throw a 1g DSM BOV on the old Starion/Conquest and get that sexy sound



It worked for us just fine with the 3" or 3.5" GM MAF sensors.

 

Is it that easy to switch where the Maf is though?

Im not sure about 240's but on the dsm's you need a translator to use gm maf's. I suppose, you could do it though, just weld in a maf after the ic and before the tb, and then run a vented BOV.


Conquests are awesome btw, i want to get another one.

 

i just used the stock bov recirc pipe on the det intake

 

Yea, we ran the translator. It was a HUGE upgrade from the ****ty Mitsu MAF.

The fiji blue Conquest is my project after this 240.. they are beast but expensive.

 

I'll post some pictures in the next few days... i got the flange welded to the intake (cold) IC pipe side... if i still recirculate it, i'll have to run a tube across the radiator into the intake
