Supercharged - Boost controller ?
I'm running a 2.8" pulley on my Novi 1200 blower and trying to limit boost to ~12 PSI. Could someone educate me on the best way to approach this?
I purchased the BLV from 928 motorsports; however it did not work. With the ball & spring completely out, I was still exceeding my target boost limit
I was thinking of installing a wastegate, but want to hear others' experiences.

I did contact 928 motorsports. They said it was the first they've heard this and suggested I run 2 BLVs. At $200 a pop, I'm going to pass. The tech did mention that their BLV flows 700cfm, but I don't believe it. Our Novi 1200 is rated ~1000 cfm. At 700CFM, I should've been able to bleed that extra boost.
I'm now looking at the Tial MV-R (44mm) wastegate and a manual boost controller. Since under-hood space is limited, I'm staying away from the Tial V60.
What a waste of time. Spent $180 on dyno, $100 on fuel and $200 on the BLV all for nothing.
The top 3 lines below are with the BLV installed. You can see that it's doing nothing. Green line is with ball & spring removed, running straight open. We cut the run at 7000RPM, cause boost was still building.

Lame! Looks like 928 is 0 for 2 with the products for our cars. Kind of su ks because its a company thats near me in WI haha.

I've recently had 928 motorsports rebuild my blower and install the upgraded impeller. Its been less than 1 month and I am leaking quite a bit of oil on both inlet and outlet side. They said I can send it back in to get it checked, so lets hope they fix it!
I will keep you guys updated.
Back to the topic though, I am very interested in the wastegate idea!

I never bothered to call back and deal with the leaking blower, dealing with them anymore was the last thing to do on my list of torture. They would just find a way to blame it on me and then I'd be out a blower for several weeks for nothing, plus the cost and hassle of shipping.
Wish you good luck Sung!

I just purchased a Tial MV-R 44MM Wastegate. I'll be installing this and will report results back.
After receiving input from Tial, they suggested running the Wastegate at the boost level I plan to run and avoid plumbing in a boost controller. That said, I'll choose the spring rate closest to 12PSI and pipe the boost signal directly into the bottom port of the wastegate. The top port will be vented to atmosphere.
