This is not at all how a real car reacts. IDC seems to be more a function of horsepower or airflow than anything else. My car makes peak IDC at about 7100-7300rpms, which is where peak horsepower is.
Yeah. I dunno what I was thinking when I was typing. Somehow PW and IDC got fucked up in my head. I'm rusty, haven't thought about this shit for a while. From there............... who knows.
All I really know is I have never really seen a fuel pump max out at max torque, the curve always starts to go lean up top as RPM's get high.

Great abbreviated explanation. Duty cycle seems to be misunderstood by most people.

Update, v0 IS in production, they're making 6 of them for now, they'll be like $500 and be a 'street' version made to work with a stock-frame turbo. Results to come in following weeks.

I like the fact that it's backed by BR, who does real world testing then puts the best manifold on his personal car.

Or just has someone make something, mark it up 400%, then tell the whole world it's born of years of development and everybody else's similar product is utter garbage. It's always a money thing these days.

So is the whole talking-shit-on-Magnus thing a coincidence(as-in, was he talking shit over the Magnus to swing his upcoming product?) or is this the crack baby that came from Buschur not liking the actual power output from a Magnus SMIM?

There is no such thing as coincidence.

The thing is steve, NO ONE is making anything like this. When you look at the process they're taking these things through, it is unlike anything everyone else is doing. I thought I posted this earlier, but its produced by Wilson Manifolds, not Buschur. Check out their www site for some freaking insane credentials (and prices, CNC'd intake manifolds are nuts!).
Anyways, they actually cut the whole stock manifold in half, shorten and flow-balance all of the runners, and somehow machine the inside of the plenum to increase its volume. Then they weld it back together and shot-peen the whole thing so you cannot tell it was ever apart. If they mounted the WM logo in a different spot, this would be an uber sleeper/stock appearing setup. Besides that, think about how much stuff you have to do when you install a typical SMIM: figure out a new TB, ISC, UICP, coilpack (on dsm's), various sensors, etc. This eliminates all of that.

I doubt it. This guy that has been developing race engines for ever (he's an old guy....older than steve hill!) approached Buschur after he had done those tests and told him that all of the manifolds he had tested were junk, and he could produce one that would kill all of them.

This sounds like what my friend is doing for his independent research project at Iowa State. I've given him a 1g and 2g manifold for testing, and he's basically taking stock ones, cutting off the plenum and a few inches of runner length, porting them, then adding a new larger plenum. However the new plenum isn't bored out stock like this, he welds on a sheet metal style one. The resulting TB location is very close to stock.
He thinks that for most street cars the current SMIM offerings have too short of runner length, but you can't really get around it unless you use cast aluminum for a curved runner. So he's going this route for a more street-optimum RPM range manifold. I'm pretty excited to test one out on my car vs. the JMFAB intake.
