Uber modified stock evo intake manifold vs DI SMIM

[stikx]

:rollinglaugh:

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.

I also disagree with the pricing since it's a stock core to begin with and we are paying 1000+ for labor and the machine work. Regardless I don't know too much about BR, except for his test's on evom, which I assumed were fair.
This manifold hasn't been tested against the HKS with a 3" TB.
BR hasn't taken the HKS off his drag car either, interesting...

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.

That was tested, a while back too. I have no idea how much actual research went into it, but they did the same thing w/ an evo manifold. It fell on its face :( Looked promising though ;)

That's pretty close to his idea. I guess I'll have to wait until Fall and see how well his perform.

How about a 3" Wilson TB on that uber modified manifold? While they got it apart, why not?

This is the indy/wilson v2 w/ 3" wilson TB:

(yes it is bolted up upside down (: )

Crazy shit.

Cali-spec manifold for california dudes, or proven race cars wishing to fly beneath the radar.

Something else about these manifolds in general, anyone looking to step up to a 'big power' manifold is also forced to look at upgrading to a 3" TB and with them come reliability concerns and driveability issues.

Furthermore, there have been quality control issues with the Driven Innovations SMIM on multiple occasions with welds breaking, runners cracking, and worst of all fuel rail mounts breaking off. These issues combined with the stock-like driveability (uses ported stock TB) make these manifolds *the* manifold of choice for top-end users.

For those that don't know, Wilson Manifolds has been in biz for *30* years making top-quality products, and this is no different. Def a name you can trust, if you're willing to pay for it.

Also, no word on the v0 manifolds yet, but real world it is probably going to perform similar to the standard ported manifold (I paid $75+core for mine), so for the $550 or w/e they're talking about charging, probably not worth the dough.

Those new pics must be the V0 or whatever, because it is obviously not cut in half and welded back together and the porting looks to be done just through the main inlet. I'd like to see that exact manifold tested side by side with a stock one and stock TB, I betcha differences are minimal.

The old guys will remember the big fuss over extrude honing 1G manifolds and the big price tag for that. Later testing revealed almost no gains whatsoever, but Buschur sold a load of them. Hmmmm, history repeats itself?

+1 No way in hell I'd pay $1000 for an extrude honed manifold when AMS VSRs are $900.

And left over material from extrude honing ruined a few DSM motors back when they were all the rage.

The guy that posted those pics said they were v2's, so they would be the ones that were torn apart and re-welded. From all the pics, you cannot tell it has been done, they are shot peaned afterwards.

Anyways, Steve, check post #19 here for a close comparison to what you are requesting.

So, how do they mate the inside so perfectly that you cannot see a line on the insides where it was cut apart?
