3. Both of those plenum options are a waste of money. As Ferris said, you need your BOV at the plenum, close to the TB's. I've never blown one this way, even with plastic lids at 10psi.
We had a customer recently crack an aluminum plenum with BOV mounted on the plenum, but he is running nearly 15-20 psi. He is adding a second BOV on the plenum and having his original plenum re-welded and reinforced in some particularly weak places (around the perimeter in particular).

Biased, my friend. Biased. Like with most companies, there is good and there is not as good.

At 15psi+, I do recommend adding a second BOV; but most people won't reach those levels. Regardless, having it downstream seems to be an issue.

Ditto, I also have a reinforcement method for the lid.

Plenty of first hand experience that form my opinion, not bias. There's good, there's trash, and then there's RK.

I'm running stock 9 psi. Offtopic question, from your experience, how high can you go (in terms of boost) on v3si, stock internals, bosh green injectors (440cc)?

Iíve cracked my plastic one in the past as well.

As Shady mentioned, you need those 4 center mounting posts. Someone local tried what you did and the results were the same as yours.

You have few options,

Get an aluminum lid
Weld the bov adapter on the lower plenum, but you donít have to at 9psi
Get a CF plenum, if cracks have it replaced under warranty
Get evolve
I totally forgot to post the solution to my problem! I got new aluminium lid, and welded BOV on the lower plenum as it's been suggested. The pedal feel is totally different now! It feels like i'm in a sport mode, even when i'm not. I really recommend doing this to anybody with SC setup!

I wouldn't feel comfortable going beyond 12 psi on pump gas.

I'm glad someone said it! That was the first thing I thought when seeing the original picture, but the latter one is even worse! Almost looks like you drive with your hood off in the winter as they are spraying the roads with salt.

It's definitely better then when i had BOV on intake pipe, even when plenum was intact.
