There are many BMF intakes in the hands of many folks now, I and I'm sure others are eager to see them hit the track/road, especially given the drool-worthy builds they are associated with!!!! Would like to hear some updates on how your builds are going and when you think you might start 'er up!

working on figuring out dimensions so I can cut down the injector holes some and then make fuel rail mounts or spacers for the ones sent. Ordered a clutch from FWDP which is the last piece of the puzzle to get this build completed. Have all the parts, need to finish the intake mods, put it together and in the car, then will need some exhaust work done.

Had to grind away on my compressor housing, backplate, and turbine housing to make the turbo fit. Also have to make a custom rod.

Lookin good!!

Hmm as far as removing I'm not sure...I know I must have done that a few times but I cant remember if I cheated somehow to make it easier so I could do fitment testing. Like grinding a notch in the turbo flange on the ex man. I know I was using a very long allen wrench I cut off with a socket to drive it, but I'm not sure if that was for the stock manifold, or the BMF or both sorry

I would suggest looking at each bolt and figuring out plan. I am pretty sure the bolts near the exh man turbo flange will be the most difficult. They may seem impossible. But if you use a long ball-end hex wrench cut off with a socket wrench to drive it, might work out. You may have to grind down the shaft of the hex wrench where it will touch the flange to get that extra bit of angle. Just assume worst case scenario here and it might go pretty smoothly

Last year, I dyno tuned my car on E85 at ~21psi, resulted in 290whp

Since then, Microsquirt, more efficient intercooler, a T04B V trim instead of a T04E 50 trim, and a chambered muffler.

This year, I dyno tuned it on E54 at ~24psi, resulted in 350whp.
I'm more surprised by my minimal boost settings, 13psi and 250whp! :eyebrows:


There are two set of dyno pulls on this graph.

Took my car to a DynoJet a few weeks ago. Looks like the Dyno Dynamics machine is calibrated really close to the DynoJet machine.

Boost starts at 7psi and creep to 13psi. Made 248whp at 12.5psi. Nice flat torque curve.
http://thelostartof.net/tryingbe/dodge/omniproject/2017/dyno/248whp.jpg

Power run spiked over 29psi then come back to a stead 26psi.

So, if your cylinder head can flow, BMF intake manifold is a great addition.

WTF wow 370whp?? Whats next for your build? Dear me

Good question to ponder.

What I know I don't care about is drag racing. I can't drive, I don't have slicks, and I broken an axle and engine mount bracket.

I can probably break 400whp since I still have injectors duty cycle to spare and my Turbo will support it.

http://thelostartof.net/tryingbe/dodge/omniproject/2017/vtrim.jpg

I can put in 4 bar map sensor to run over 29psi, but I like efficiency than just raising the boost.
I used E54 for the dyno, but I have access of E70 and E85, which means I can run more ignition timing and add power that way.
I also have a different camshaft I can try and see what it bring.

Weather is starting to get warm so if I want to change parts/fuel and tune, I'll have to do it before summer.


So, 4 map sensor, E70/E85, and different cam shaft. I'll probably try the camshaft first since I own it and I can compare logs.

Looking at Tryingbe's build I see that the top end is almost identical to mine. Same FM head with the IMSA sized valves, and BMF, and hybrid turbo (mine is a 50 trim)

Mine is a 2.5 and has a stock camshaft. This year I would like to get it on a dyno and maybe find a camshaft for it. I have a feeling that I'm going to need to get into the bottom end again before its all done, With the stock cam this thing likes 5500 to 7000 rpm a lot. I even had this thing to about 7800 rpm before but I am afraid of the bottom end.

I am running stock electronics but I am on E85 and run 18 psi and so far I have not been knock limited at all, at one time I had it up to 37 degrees of timing with no knock (cool day no heatsoak)

I entered the data into the excel version of the turbo calculator from the Dyno Graph and my MS log, it turned out the dip in the dyno is when my engine experienced surge.

http://thelostartof.net/tryingbe/dodge/omniproject/2017/dyno/367whp.jpg

This is a rough graph, but it shows enough to let me know I had a surge issue. I have since make my boost control more stable (less boost spike), and I did not experience surge at the drag strip.

Good question to ponder.

I can put in 4 bar map sensor to run over 29psi, but I like efficiency than just raising the boost.

Efficiency, such an elegant word, but even in this day and age and after all this community has witnessed, prob the most misunderstood ;(

With the wrong turbo, 25psi boost Could be inefficient, while with the right turbo, 40psi could be Optimum Efficiency!

Still the #1 problem with turbo builds I see (other than lack of maintenance and common sense, attention to detail) is the misunderstanding that making more power on less boost = Efficiency.

Don't get me wrong, there is validity to this statement, to a mechanical degree of the engine itself, but it will always be completely Relative to the turbo that is being run.

So just to clear the air and make things completely seeable;

For any given engine size and power level, there will be an Optimal turbo charger (optimal compressor and housing mated to optimal turbine wheel and housing) and it will Need to operate at it's optimal pressure Relative to That Specific engine build!

So you could be running a turbo and build that will only see 100% efficiency @ 35psi and your running it @ 20psi because you think that's efficiency. Then, rather than increase efficiency by raising the boost, you decide to put a different turbo on to make more power on 20psi, making the entire pkg Less efficient!

Now, if you want to argue that you entire goal is to make the most power @ 20psi Period, and that is you criteria of efficiency for your build then so be it. Just understand that it doesn't mean the build is making power as efficiently as it could.

If your feeling lost, don't worry, your not alone. I've been trying to explain this for what seems like my whole life lol

No better eg. then what happened on the Dart forums with Tork motorsports. A once supporting vendor that was going to produce an efficient upgrade turbo for the 1.4l Dart turbo platform. When they announced the spec of the turbo they were going to build I cautioned them that it most likely would not work. The guy representing them blew a gasket and tried to flame me for even thinking I might know something that they didn't, rather than just take some sound advice. After all, who was I compared to all of the Top people they had passed this buy and all of the Experts that said it Would work?!

I further explained that my biggest concern was that they invest all of this R&D into something that was doomed to fail from the start and end up Defeated and No upgrade turbo for the Dart and now I have to build it.

Well that's exactly what happened. A year and a half with promising updates, its all working good, just need to sort a few things out, then it finally comes out; Total failure to launch! So upgrade was scraped and very soon after Tork disappeared from the Dart forums after Promising that it Wouldn't defeat them and that IF they failed like I had warned, they would just learn from it and have another go!

So what was the Crucial piece of the puzzle that they dropped the ball on? The lack of understanding that more power on lower boost = Efficiency!

They had made somewhere near 240WHP on the stock turbo @ 28-31psi boost and at a pressure differential of something ridiculous like 7:1.

Without a thorough understanding of drive pressure and turbo sizing, they now planned on building a turbo that could support 250WHP @ only 15psi!

Could that be possible? Sure it could, with a turbine wheel and housing that would be too large for any drivability to be left in the Dart! lol

So to retain drivability, they decided to retain the stock turbine housing and wheel, which was absolutely ludicrous!

I tried to explain to them that the 7:1 drive pressure from a turbo pushing 31 psi vs the same turbo with different compressor pushing 15 psi making the same power would be the Same! To no avail............

Moral of the story = they defeated themselves by placing an unrealistic goal of making X amount of power on X amount of boost instead of Respecting the environment of the build in front of them.

#1 The engineers at Fiat and Chrysler already showed that to make 160hp on the multiair 1.4l platform 20psi boost pressure was required to also retain some semblance of drivability. To believe your going to make any significant increase in power at Less boost pressure was a big mistake.

#2 They had already logged 7:1 pressure differential through the stock turbine wheel and housing @ 240-250whp. To believe that lower boost pressure on the intake side would equal lower drive pressure on the exhaust side at the same power and Through the same hot side was a Big mistake. (we went through this on TM some years ago and very few other than W.S. got it IMS)

#3 Understand and respect the environment of the build in front of you! Generally speaking, as an engine gets smaller and smaller, the characteristics of the turbocharger become reversed.

Big V-8 = low pressure compressor with huge turbine wheel and housing that flows large amounts of exhaust at relatively low pressure and low operating speeds. (120-150,000rpm for eg) This turbo Can't operate Efficiently at High boost pressures! (eg 20ishpsi or less)

Small displacement 4 cyl = High pressure compressor to be able to Sustain boost pressure through restrictive environment and smaller turbine wheel/ housing that operates at much higher pressure and rpm. (170,000+rpm) This turbo Can't operate Efficiently at Low boost pressures! (eg, 20ish psi or More)

There is far more to it than just this, but in a nut shell, Don't shoot yourself in the foot by believing that that the boost pressure # Alone is all there is to Efficiency!

Good on you Harry, that you discovered that the B-trim wheel is less efficient for our particular 8v's than the E wheels above 15psi :clap:

You have to Rev to get more work done ultimately. So you need some top end for HP. Next is flow. So if the system is working, lowe pressure differential to zero. Then you look at a realistic psi per boost goal and match that to the compressor map. A balance of volume at that goal pressure. Given of course there system works right again. A local here does 407 whp on his NSRT4 with 15 psi of boost. A lot of flow with porting and cams, a big turbo that flows right at that target volume / psi. The BMF intake of course makes the engine work right so you can look close to 16v maps. But I have no doubt you could make 200 HP na with a bmf. The na starting point with most is about 120 HP with a built 1 piece car. This chosen your turbo for you by map alone

I have to wonder who's grandma would want a turbo upgrade for her dart ?

1.4 litre waste of time

did tork go bye bye before or after the dart line did - there might be a reason they're gone in that

We live in a world where FCA makes a 800hp challenger that could easily be driven across the country and a 700hp SUV. That's pretty badass to me. Not to mention the SRT8 Durango that can run 12's or tow almost 9000lbs.

Ok, steering this thread back on track a bit. Finished up the model for the throttle arm modifications I have to do for the 76mm TB I bought for my BMF intake. Might machine it up this week if I get some time. Still need to figure out the end and bends to get to where I want the throttle to sit in the engine bay. But that's pretty easy.

I think I came up with a way to eliminate the elbow on the intake

I have a Lengal plenum and want to add a larger aftermarket throttle body

instead of the TB mounting that the plenium came with I want to cut it off and add a sphere like shadow did to both ends of the BMF he was putting together but I only want to add the sphere at the TB end
then simply weld the base mounting for the TB at any angle I want , no precision angled or cut elbow needed just weld it on at approximately a 45* angle as I want to mount an intercooler over the trans & battery tray area so I don't need a 90* off the intake as the intake tract isn't going to run right past the end of the head anymore but rather over towards the old battery location

How much is the dome? You can get an aluminum 90 in 2.5 or 3" for under $20. You can get 45's but they are a couple bucks more.

IF I remember correctly I think the price is in the same range

I was about to ask shadow about it as I thought I'd found a boomba 70mm neon TB locally on the cheep but I haven't heard back from the seller yet so that fire died some

The 5Ē hemispheres were quite affordable from a manufacturer called ďfat daddioísĒ at Amazon.
Shadow and I both had this idea. I believe we discussed it in the BMF R&D thread waaaay back when.

Gonna have to turn the air somewhere. The problem I see with moving the mounting point on the Hemispherical is that you run into the possibility of starving one side of the intake vs the other for air. Maybe I'm wrong but if 2 molecules enter at the same point but one has to travel further to get to the same spot you know how it goes.

Example pics on BMF size Hemi with 3" opening. . No I'm not gonna take the time to get Solidworks to do a flow analysis.

Dr. Johny Dodge

well, you have a long and short distance example just looking at the inner/outer radius of the elbow
plus the limited elbow inside diameter right at the end of the plenum beside the runner to cylinder #4

the sphere would allow plenum "volume" to begin right at the throttle body - over past #4 maybe giving #4 a better chance to catch a breath

also the angled inlet would in part direct flow at the rear inner side of the sphere
this in turn might also help #4 as part of the air mass should stall as it hits the rear inner surface

though my reason for the thought was mainly about "packaging" the parts combo I'm considering in my limited L body engine compartment

I found another accel two stage foam panel style air filters to fit a 2.2
these filters have almost zero restriction when you blow through them and in an L body you can even feel a slight difference in throttle responce on a stock motor

planing a flat charger hood with a small mopar "pro stock" style scoop
I can build a simple air box under the hood to feed a log motor style air box from the top , mounted in the stock log motor filter position
a simple tube can connect from the back bottom corner to the turbo inlet
the compressor outlet can pass under the filter as it does on a TII

I can fit a much larger a2w intercooler in the area in front of the master cylinder & strut tower than beside the head like many seen here already - IF I relocate the battery

if the sphere is welded to the plenum and I mock up the build I can find the perfect mounting angle for the TB base easily without guessing or presuming about fit

and if I had the hole in the TB base plate cut to match the radius of the sphere I can save the thickness of the plate from the overall assembly length

as for the manifold support bracket like the TII ones - I think I remember reading that had more to do with making the knock sensor accurate than supporting the neck ( & rear weight) of the intake

Wonít this shield trap the heat around the intake runners?
Itíll help keep the fuel rail cooler, but at the cost of heating the air in the runners, no?

Donít get me wrong, I like it, and I intend to build a shield between the intake runners and my header myself.

Good to see others attempting things like this. 👍🏻

Don't really have an issue with AIT when normal driving or in boost according to my log. I moved the AIT sensor to deal with the heat soak of the intake manifold.

Here are a couple pics of BMF manifold that I had welded up locally. Went with hemispherical ends. Thought you guys might like to see what runners look like from perspective not many people see, because most probably bought fully welded. Couple photos of runners before the ends were attached. Had to clean up with carbide rotary files and sand rolls. because of the penetration drop through, but it looks pretty nice. It is attached to a really good flowing BV head too.

I didnít consider the over the V/C T/B idea. I saw someone do it somewhere, canít remember who.

With the HE351CW, 70mm T/B, and 3Ē mandrel elbow I should be able to get enough air in there that it wonít matter where itís coming from 🤣
