Has anyone seen these for the LSx engine? the obx stuff is a bargain and the quality looks to be pretty good

I'd like to see how these would do with a plenum welded on the end and a twin turbo setup

I have the hot side already with a pair of older T60 turbos and I think this would look awesome!

probably won't make that much more power but I'm intrigued by it from a wow factor

Don't use ITBs on a turbo set up. And don't weld a plenum on an ITB setup it defeats the purpose.

I suspect Supra, Skyline, BMW, Audi and other big power turbo setups would disagree that a large plenum on an ITB type setup is defeating anything.

It's exactly how they build them.

But I presume from a simplicity point of view, he'd weld a plenum onto the bases and retain a single blade per plenum.

I just cant see the time/effort/money being worth any gains though, but I had thought of doing it myself.

Even more so given how well some guys are doing with the factory plastic intakes these days which are basically zero cost.

The benefit would still stand allowing for a large cam to run relatively smooth with the ITB's. A plenum on the atmosphere side is generally not a great idea for N/A but turbo it cannot hurt. A shared plenum on the vacuum side is what would defeat the ITB major benefit(isolating individual cylinder vacuum).

From what I have heard the OBX stuff has some tolerance issues and with the heating and cooling of the engine, the blades get stuck. No personal experience though.
