george.bryant Posted March 29, 2006 Share Posted March 29, 2006 Hey guys, Where abouts and on what intercooler pipe etc should I place my blow off valve. This is the cooler. I know its now huge but its better than no intercooler Thanks. George Quote Link to comment Share on other sites More sharing options...
Guest ON3GO Posted March 29, 2006 Share Posted March 29, 2006 close to the T-body.. now i have had it both ways and never had a problem but next to the t-body is where most ppl say is the best location. mike Quote Link to comment Share on other sites More sharing options...
george.bryant Posted March 29, 2006 Author Share Posted March 29, 2006 so i can go right next to tb? Quote Link to comment Share on other sites More sharing options...
Guest ON3GO Posted March 29, 2006 Share Posted March 29, 2006 ya just before the t-body. mine is like 6in's before the t-body Quote Link to comment Share on other sites More sharing options...
AK-Z Posted March 29, 2006 Share Posted March 29, 2006 I don't know. I'm guessing the inlet of the IC. Would help with response to surges Quote Link to comment Share on other sites More sharing options...
Guest 280ZForce Posted March 29, 2006 Share Posted March 29, 2006 usually is placed 8-12" before the throttle body, which is the charge pipe. but as long as it's anywhere on that pipe between the tb and the i/c u r good. Quote Link to comment Share on other sites More sharing options...
stony Posted March 29, 2006 Share Posted March 29, 2006 heres where i put mine I have seen alot of people put them in the pipe betweent the turbo and intercooler and route the outlet back into the inlet of the turbo. Quote Link to comment Share on other sites More sharing options...

z-ya Posted March 29, 2006 Share Posted March 29, 2006 I have mine about 12" downsteam of the turbo outlet. Made it easy to plumb the BOV outlet back into the turbo inlet (like to keep it as much as a sleeper as possible). Quote Link to comment Share on other sites More sharing options...
zbuild Posted March 29, 2006 Share Posted March 29, 2006 When I built mine I heard near the outlet of the turbo Quote Link to comment Share on other sites More sharing options...
george.bryant Posted March 30, 2006 Author Share Posted March 30, 2006 Yeah my tutor said as close to the turbo as possible. But alot of ppl say as close to the tb as possible. I have mounted it about 6 inches down form the tb Quote Link to comment Share on other sites More sharing options...

I have mounted it about 6 inches down form the tb Maybe we should mount two BOV's one before the TB and one near the Turbo...lol:icon56: Quote Link to comment Share on other sites More sharing options...
george.bryant Posted March 30, 2006 Author Share Posted March 30, 2006 Would that actually work....? Quote Link to comment Share on other sites More sharing options...
AK-Z Posted March 30, 2006 Share Posted March 30, 2006 I would think the one near the turbo would activate before the one near the TB. Quote Link to comment Share on other sites More sharing options...
JustinOlson Posted March 31, 2006 Share Posted March 31, 2006 Placing a BOV near after the turbo before the intecooler is a better setup. I have placed a MAF sensor on the outlet of the BOV in both positions(near the throttle and right after the turbo). Placing it after the turbo results in higher flow measurements, thus the turbo doesn't slow down as much pushing air through the intercooler.

thehelix112 Posted March 31, 2006 Share Posted March 31, 2006 Justin, So because you are flowing more out of the BOV, ie, wasting more air, that the turbo then has to replace before the engine sees boost again, that is better? Maybe if you had a turbo tacho log as well to show us that the turbo didn't in fact slow down as much, and a log over boost pressure as well to show us that the gear-change lag is shorter?

AK-Z Posted March 31, 2006 Share Posted March 31, 2006 I can see benifits of having one on either side. Near the TB; less lag, better throttle response under boost Near the turbo; less preasure against the compressor wheel from the outlet side, maybe slightly better turbo life. Just stating my observations. Quote Link to comment Share on other sites More sharing options...
thehelix112 Posted March 31, 2006 Share Posted March 31, 2006 AK-Z, Having it near the T/B will mean the compression wave caused by the closing of the T/B is further away from the compressor wheel than if it was near the turbo. Dave Quote Link to comment Share on other sites More sharing options...
JustinOlson Posted April 1, 2006 Share Posted April 1, 2006 The more work you make the turbo do, the more it will slow down between gear changes. That is where you lag will exist. When the compressor slows down and has to get back upto speed when you are full throttle again. The pressurization of the system is a very small portion of any inherent lag you will feel.
