the procharger techs told me you always want the bov on the hot side of the intercooler so the intercooler isnt working at 100% all the time, that way your releasing the majority of the hot air out b4 it runs threw the intercooler and heats it up when your not wanting it to work.

 

Higher pressure would make the valves more effective.

 

The location was more of a packaging deal. I didn't want the weight of those things hanging on the longer pipe. Being that the intercooler will have ice water running through it, I'm not too worried about efficiency of the intercooler. Also, I certainly don't have to worry about effectiveness of the bov's as 2 is way over kill. If I wasn't trying to run a belt to drive the blower, I would have likely only used one.

 

Updates?!

 

I think the bigger issue with the valves is not putting undue stress on the tb or blower wheel after suddenly slamming g throttle closed after blower was at full tilt.

I'm not being critical. I think ur build is amazing and I can't wait to hear it make a pass! My comments are only trying to help. That said, is ur tubing the thin wall stuff or the thicker. If its the thin stuff those valves (extension stands) will crack where they weld to the tube after a handful of passes (ask me how I know). My new combo, the valves are welded on like urs. The old combo (thin wall) cracked and I ended up having to weld a plate on the tube first, then the extension. Just trying to save u some potential aggravation. Good luck.

 

One word, DAMN!!!!! Awsome build!

 

the tubing is .065 wall

 

That sux. When I had the .065 wall, mine cracked after a few passes. See before and after pics. New combo is using .125 wall in that area. I guess, see what happens and keep an eye on it. Good luck.

 

My guess is that your stuff cracked there because the BOV was put on the outside of the bend. .065" mandrel bent tubing is around .040" thick on the outside bend.

Plenty of people running these bov's on .065 wall aluminum tubing. Your's is the first I've seen do this.

Hope I don't have this problem, but mine are not mounted in a bend for this reason.

 

Good point. Sounds like it should be fine then. Keep us posted and we want Video!
