Now both of these cars come stock with a BPV. If the STi wants to upgrade to a BOV he can without having to custom make anything.
Now I heard that the Synapse BOV valve can be worked to recirculate or vent to atmosphere and the TC SC cant have a BOV that doesn't recirculate.
Would it be possible to custom weld a pipe from the SC to the throttle body and have a recirculating BOV welded on the throttle body pipe?
I also youtubed a comptech s2000 supercharger and comptech makes it in the same style as trd which is the centrifugal type.
Would it be possible to make it work on a supercharged tC?

 

just get an atmospheric bov it works fine.

 

Now if I just get a fully atmospheric, doesnt the BPV for our SC have to connect with the SC intake. If I just get a bov, I thought it only connects with the throttle body and vac line.

 

just get a silicon 1" cap for where the stock bpv tube connects to the s/c.

 

Wow, that's completely safe?? Lol, just sounds a little odd that one end is going to be blocked off.

 

makes you run rich between shifts, makes for some nice backfires if you have a full exhaust. Thats about it, you don't need to go recirculating if you don't want to.

 

Oh okay, i'll dig into that some more. Trying to get a blowoff on a sc to make up for not being able to have a turbo cause of stupid cali emissions.

 

uhhhh..... what about the problem of the ECU anticipating all that metered air?

 

What do you mean? From all the air being vented?

 

its not a problem like i said you run a little rich when you let off the throttle big deal you get a few backfires and thats about it.

 

This isn't something that can be tuned out is it? Cause when I get my SC on, i'm def. taking it to get tuned.

 

it is, but that's annoying.

just run it like that

 

Im going to have to get tuned anyways, so I might as well! Lol...
