Default Installed Stratmosphere HyperBoost BPV.............

Has anybody that may have installed these notice that they fit very snug (which is good) but in particular the passenger side? I was replacing the S hose and it was tighter than normal and didn't fit like a normal S. More like a very tight S shape. (yes Imagination has to take over at this point due to not having pics). Functionally they are outstanding, I am just a tad curious as to the wear and tear of the S hose in it's new cramped position.

Default I installed them in a friend's car,

they are very tight, i had to add a little lithium in there to get it on and just keep having on eye on it everytime we hang out. I do have to remind him to keep the hose clean and mosturized. Being the performance junky he is though, it took quite a bit of discussion to convince him the tight "S" isn't much of a detriment.

Default Yep, I have the Strats and it's tight. I put a large bolt in between the...

S-hose and the part it is crammed against so that the S-hose would be more straight (thinking that a cramped S hose would have restricted airflow). I've heard that the cramped hose is no problem, though.

Since then, I've switched back to 710Ns. I like the quicker response between boost/vaccuum than the large/heavy Hyperboosts.
