2K4 STI Posted October 16, 2007 Share Posted October 16, 2007 Has anybody else tried this setup http://www.ultimatesubaru.org/forum/showthread.php?t=64741&highlight=exhaust Just curious how it runs and if you would have to do any more tuning after doing this.

beataru Posted October 16, 2007 Share Posted October 16, 2007 You would not have to do any more tuning as far as I can tell, But I have to be honest and say that I have seen many many turbocharged cars, and this is the onlyone with this setup.

simple monkey Posted October 16, 2007 Share Posted October 16, 2007 dont a lot of people do this when they have a GT30or GT35? even tho you wouldn't need to make huge adjustments, it would still be wise to re-tune. Quote Link to comment Share on other sites More sharing options...
2K4 STI Posted October 17, 2007 Author Share Posted October 17, 2007 Thats what i was thinking but i wasnt sure on these cars Quote Link to comment Share on other sites More sharing options...
beataru Posted October 17, 2007 Share Posted October 17, 2007 what are you talking about retuning? are you running aftermarket management? if your not, these things will tune everything themselves. Quote Link to comment Share on other sites More sharing options...
simple monkey Posted October 17, 2007 Share Posted October 17, 2007 what are your plans exactly? as far as running a BOV to the Atmosphere, i have had no issues with mine, doesn't run rich between shifts or long off throttle periods. try the blow thru setup and document whether you needed to tune it. be a pioneer.

Numbchux Posted October 17, 2007 Share Posted October 17, 2007 it's extremely common on big power new-gen guys (I can think of 4 local cars putting 400awhp+ running blow through). BUT, the only point is so you can run a BOV instead of a BPV. which, at anything less than about 20psi, means nothing but a loud "pssshhhh" sound when you let off the throttle. zero performance gains whatsoever.

beataru Posted October 19, 2007 Share Posted October 19, 2007 Some would say that sound adds rear wheel horse power Quote Link to comment Share on other sites More sharing options...
Jabbott126 Posted March 17, 2014 Share Posted March 17, 2014 Hate digging up old threads but there are big benifits to having a blow through setup. First off the bov can be ran to the atmosphere (like you said doesnt do much under 20psi) but apart from that it will also save your rump roast if you get a bad boost leak. The car wont care if it has a leak lime it does when the maf is in the begining of the system because maf's work by metering air intake. So the car will only care about the air that has pasted the maf and nothing else. So in other words the closer to the throttle body your MAF is the safe you will be and the more accurate on air accuatly going into your motor Quote Link to comment Share on other sites More sharing options...
subyrally Posted March 18, 2014 Share Posted March 18, 2014 wow, talk about digging up the dead, lol. i would have said about the same though, it has definite benefits, especially if you are running a custom setup. ive lost count of how many times i had an intercooler pipe come loose or a hose clamp slip when i was first messing around with turbo engines. it was annoying trying to figure out what was going on when the car wouldnt run due to the boost leak after the maf.
