Uber modified stock evo intake manifold vs DI SMIM
So Driven Innovations is the SMIM of choice for a lot of evo guys now. Well this guy that was deep into engine design for high-end race cars got involved, and started modifying stock manifolds to yield similar results. V2 of the manifold was just tested, and the results are astonishing.
Here is the dyno sheet (the solid line is the DI intake, the dotted is the Indy): http://img.photobucket.com/albums/v2...mpDIvsINDY.jpg Freaking INSANE when you consider that the DI manifold was done with a 3" TB and the Indy mani was done with a ported stock TB (65mm, 2.5"). These numbers are 40+whp over what a stock intake manifold would produce. More info here: http://forums.evolutionm.net/showthread.php?t=352290 It would be *really* interesting to see what one of these would do on a maxed out IX or Evo Green car... |
Re: Uber modified stock evo intake manifold vs DI SMIM
Thats fucking sick. I wish DSMs had the same thing.

Re: Uber modified stock evo intake manifold vs DI SMIM
Update, the SMIM & 3" TB this is tested against are $900 and $600 respectively. So really this "Indy v2" manifold is $1550 + $300 for the 65mm ported tbody. $400 extra to run a stock appearing manifold that makes similar power, and you can run all of the factory sensors, mounting brackets, and even emissions equipment. Not bad.
Also, the SMIM runs were done with a slightly slipping clutch right around torque peak, so the numbers are off slightly. We'll see what happens when its re-run out to 9,000rpms. |
Re: Uber modified stock evo intake manifold vs DI SMIM
nice one a modded stock intake mani but the price is just dumb
The V1 intake is going to be $1350, you must send in a core. The V2 intake is going to be $1550, you must send in a core. I could never spend that much on a oem modded intake. |
Re: Uber modified stock evo intake manifold vs DI SMIM
Sounds like there is going to be a v3 too.

LOL 1300 bux+ for a modded stock intake? LOLOLOLOLOLOLOL
Good results....but the price is not justified imho. |
Re: Uber modified stock evo intake manifold vs DI SMIM
Considering its way cheaper and outperforms the HKS Kensei and Full Race Hypertune ($2000 each) which were the front-runners in power before, this is pretty spectacular bang/buck.

Re: Uber modified stock evo intake manifold vs DI SMIM
I guess they're gonna do a v0 'street' manifold for $575, we'll see what that does performance-wise.
There will be no v3 as of now, they're going to work on a mani for the evoX now instead. |

I'm gonna make a v(-1) and fill in the runners with JB Weld for only $450. It's nice how that car on the dyno sheet revs so high all the way to almost 7500rpms showing how these intake manifolds really perform uptop; ugh. |

Riiight, you were one of us not long ago cher, and you still are at heart ;) Did you buy an IX yet? :)

Re: Uber modified stock evo intake manifold vs DI SMIM
I guess the car was basically out of gas (C16) when they performed these tests, thus the low rpms... ?

Re: Uber modified stock evo intake manifold vs DI SMIM
After peak torque you need less fuel the higher you rev the engine, unless you have boost creep or something like that. Why not over lay this with a stock intake manifold on the car?

Re: Uber modified stock evo intake manifold vs DI SMIM
VE or pulse width might be highest at peak torque, but duty cycle and fuel needs will often continue to rise with RPMs.
|
Re: Uber modified stock evo intake manifold vs DI SMIM
The way I have always looked at it, is that you will run out of injector at peak torque, but you will run out of fuel pump at High RPM's. Dyno results seem to agree with my thoughts in my experience.
At peak torque if the duty cycle is 100 percent, you are out of injector, after that point, you won't run out of injector, but because fuel flow still tends to increase (especially on cars with long powerbands) fuel pumps will die out at high RPM's if the car is still making power. |

This is the DI mani w/ 3" TB vs ported stocker w/ 65mm (ported stock) TB: http://img.photobucket.com/albums/v2...othersheet.jpg gained 36whp and 32wtq over ported stock stuff, which is worth 10-15whp over untouched stock stuff. Quote:

Re: Uber modified stock evo intake manifold vs DI SMIM
Duty cycle determines when you run out of injector. Duty cycle is effected by both pulse width and RPM. Torque, pulse width and VE follow the same curve. Duty cycle does not. With higher RPMs, there is less time for an injector to be spraying, so it maxes out easier.
At 5000RPMs 16ms of pulse width might be around 65% duty cycle, but at 8500RPMs only 14ms of pulse width is 100% duty cycle. For example a 300whp B16 turbo Honda that makes peak power at 8200 RPMs will need more injector than a 300whp fwd DSM that makes peak power at 6500RPMs, but more torque than the Honda. A set of 450cc might be good to 300hp on most DSMs, but only good to 275hp on high reving Hondas. |

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. |
Re: Uber modified stock evo intake manifold vs DI SMIM
Great abbreviated explanation. Duty cycle seems to be misunderstood by most people.

Re: Uber modified stock evo intake manifold vs DI SMIM
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.

Re: Uber modified stock evo intake manifold vs DI SMIM
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. |
Re: Uber modified stock evo intake manifold vs DI SMIM
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?
|
Re: Uber modified stock evo intake manifold vs DI SMIM
There is no such thing as coincidence.

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. Quote:

Re: Uber modified stock evo intake manifold vs DI SMIM
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. |

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... |

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

Re: Uber modified stock evo intake manifold vs DI SMIM
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: http://i238.photobucket.com/albums/f...s/DSC_0309.jpg (yes it is bolted up upside down (: ) http://i238.photobucket.com/albums/f...s/DSC_0313.jpg http://i238.photobucket.com/albums/f...s/DSC_0308.jpg Crazy shit. |
Re: Uber modified stock evo intake manifold vs DI SMIM
Cali-spec manifold for california dudes, or proven race cars wishing to fly beneath the radar.

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. |
Re: Uber modified stock evo intake manifold vs DI SMIM
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? |

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

Re: Uber modified stock evo intake manifold vs DI SMIM
So, how do they mate the inside so perfectly that you cannot see a line on the insides where it was cut apart?
