Edit: I'm confused. BRB.
Okay, back. Lost track of what graphs went with which manifold.
I am really liking the power curve of the Kinetix Velocity. I would gladly give up 5hp over a 1K rpm range vs losing over 25hp as you near 7200 rpm. There's a real difference in overall power there and extending the power range like that has great dividends. I can only image that adding cams to an N/A setup would greatly benefit from this smoother flow pattern.
How are these Velocity manifolds performing / holding up under boost?

The Motordye Mrev2 lower plenum appears to help, losing on 15HP from peak to redline.
I took this dyno chart from a well tuned vehicle in this thread:

^ More than likely a function of whoever was tuning it; and it's a solid tune. It's relatively flat from 5750 - 6250, so "peak" isn't dramatic for him. If you look at the previous run, the peak is where you would expect it.

Yeah, and I guess Kinetix isn't being too helpful in telling the difference between the models. Unfortunately they didn't use serial #s either.
What size is the intake pipe on these things? I think the stock throttle body bolts right up? Does that mean that a larger TB like the 75mm & 80mm is larger in diameter than their pipe?
I was considering building a modified stock intake similar to SG's, but I do like the idea of lower intake temperatures and the drop in weight. Both are considerable amounts.
If I were to build a modified manifold similar to SG's, it would be a design I could have produced here in the DFW area to sell as a Non-Profit item for the community.

Well this just delayed my valve cover fix. However Bmurray found me a hella deal that I had to buy. What I paid saved me over 400$. WHich will pay for the NWP 75mm TB. So the dyno will show before with bad oil leak and 4-5 Spark plugs firing with bolt ons and PPEs. THen several several months later No oil new plugs and no md spacer and this manifold. Then the TB. maybe a few pulls on manifold then reutned. Then off with old TB on with 75mm. Maybe 2 runs then retune
