I thought it was pretty well accepted that it's better to have the BOV on the cold side.

i'm sure people have tried with success, however i saw a 302 hp b18c launch a rod after only 7000 miles. the 10:1 compression is just a bit to much. That said if you use LS pistons, over 300 is possible safely. Just my experience and i am not questioning yours.

why... I had way more room on the hot side, people suggested about 1ft from the tb is key but as you can see theres no room. Works either way

preference I guess, I daily my mazdaspeed6 awd with 300whp, solid motor and rear diff mouts, and I like driving my 91 miata better, its slow, but its much more fun...

WTF? Aim it down or to the passenger side, between the headlight. I'm assuming you'll use a cheapo bosch bov, as you don't seem to want anything flashy under your hood, and you don't want to spend a lot of money. They're $25 shipped on ebay, less if you're lucky, and are fairly small.

You want it right by the throttle body so when the butterfly valve shuts, the compressed air is shoved right out the bov, and when you open the throttle, the compressed air is already knocking on it's door, instead of 3' of pipe and an intercooler behind.

My understanding is that a BOV on the hot side is more efficient since a cold side mounted one doesn't account for the restriction of the intercooler. It may also help cool the intercooler for that split second it doesn't receive hot air and, since the BOV is right at the turbo, the remaining air lingering on the cold pipe would decrease next gear spool up.

In reality it doesn't matter, either is fine and there is no evidence of it being otherwise exists.

my ebay bov works fine and i trust it more than a plastic bosch bov

Curly your argument makes sense, but if you put it before the intercooler, the rapid decrease in air pressure inside the intercooler would chill it wouldn't it? I mean sure perhaps 1/1000th a kelvin or something. Its science, it works bitches.
