I’m keeping my fingers crossed. I think it’s great that you are taking this on. Just curious Charles did your design(s) go through the RB flow test yet, if so how do they stack up? Or is my question still a little premature yet?

Waiting on the man (Gil) to get the man (Bob) some 2.4L valves to do the flow test.

I have ZERO question as to how well it will flow well and also if it balanced.

So It will be does it flow as good as a side draft ? better than a 1.9L EFI ? better than a standard downdraft ? etc.. etc..

Where does it fit ?

Long story short..

• Plenum is Larger than stock 1.9L EFI by about 25% in volume
• Runners are shorter than the EFI intakes, and less restrictive
• The runners are longer and more balanced than the stock downflow intake
• The throttle body and opening is 60mm ventri with a slope to help tip in. But about a 20% increase in surface area

Ventri surface area as a point of reference

32+36 = 1820 sq mm
38+38 = 2168 sq mm
52 (EFI Stock) = 2123 sq mm
40+40 = 2512 sq mm
60 = 2827 sq mm

Now I hear you saying that could make the car touchy during tip in off of idle.. and you would be right EXCEPT..

The Throttle body I picked has this ramp at the base to only allow the top of the ventri to up from 0 to about 20% throttle.

The first 5% of throttle you have virtually only half the face of the ventri opening

This should help with the issue of the throttle being to big.. think of it like a 32/36 having a primary and a secondary.

I have a feeling this will flow as good as a single midi sidedraft intake and be possibly better balanced due to the plenum buffer

The real test will be when on a car and you can run the snorkel to the front of the car for a little naturally forced intake with no AFM in the way.

I might end up getting one.

Hmmm.... For you I wont charge for the custom anodization

Here's some thoughts: .....

how about this option: Sell the 3 manifold parts seperately and let the buyer weld them up themselves. This way, the buyer could grind and flow and weld away anything that displeases them or that they imagine will create more flow and then weld it up themselves. They could anodize or paint or use some sort of other coating themselves.

The thought of selling a few of them with no prep and no welding has crossed my mind, if anyone is interested. Thing is given the price to do the machining of these three parts, the cost "savings" in not having them welded and anodized is actually really really low. To the point of not bothering.. BUT if someone was so inclined I could make it happen. But dont expect a discount.

Kind of why I am also not selling without the throttle body and all the other parts. Once I deduct the costs of those add ons.. the intakes cost is so much more the discount in the overall scheme of things is very small. I am virtually selling this with zero markup on the accessories and loose items, to keep the overall cost of the kit below $2000.

I guess there’s one of each in every crowd as far as customizing. For the first time I’m seeing a complete FI set up for the 1.9 lower port cylinder heads coming together without having to get scrappy putting things together for us earlier CIH guys. I would definitely be interested in installing the whole thing out of the box, as is, in the not to distant future. Gotta swap out the rear end finish up some interior upgrades then it’s time to get to this fun stuff.

 

[GoinManta]

Well things are moving fast.. as we tighten up the last few items.

We are working with kptronics.gr on a Speedunio / Tuner Studio solution for the GoinManta MPI system. Plans are to have it available with the wiring harness and Bluetooth connectivity.

All Products

The unit and harness will be specific to the Opel CIH and our sensors, cost looks to be about $390.

Roughly the same cost as the Microsquirt, with harness.

The differences will be :

• Bluetooth module baked in ( extra cost on MS )
• Stepper controller for the IAC built in (extra cost on MS )
• Harness will prewired, and only need 3 or 4 wires terminated (Ground, Switched power, Battery power, Coil)
• Water resistant housing so you can mount in the engine bay.
• Base CIH tune already setup to work with the sensors of the kit out of the box.

With this final piece of the puzzle. We should be able to have the first 10 units by Mid-Summer. My Goal having deliveries of the complete units, before the one year anniversary of me going down this rabbit hole.

 

[GoinManta]

Well due to limiatations of the speeduino system.. and trying to make this the best it can be.

( I hear Mike P laughing already.. )

I am trying to create a new wheel for the VW distributor. Getting prices now.

It will be a bit tricky. But if successful, we will be able to run wasted spark and coil on plug on the kit.

 

[GoinManta]

12- 1 wheel so the new ECU and harness will make the system run wasted spark and have better resolution..

With this and the ECU guy, and such.. it will be pretty much a drop in kit. It will even have the firmware setup for the correct sensors and such, along with a base CIH tune baked into the ECU, to give you a good initial startup. If your motor is a base 2.0L it should be good out of the box.

 

[GoinManta]

So the FULL Goin MPI kit is now finalized. and has improved a bit. The distributor and ECU are no longer separate things..

They will come in Gray ( The "Factory color" ) or Silver ( Chrome like ), Red, Blue, and even thinking of doing a Yellow one..

The price for the full kit has DROPPED to $2299 and you get :

The Fuel side :

Custom Intake CNCd' out of Aluminum
Throttle Body (60mm)
Throttle cable bracket
IAC Step motor ( Built in to Throttle body )
TPS Sensor ( Built in to Throttle body )
Intake mounted MAP Sensor
Thermostat Sensor ( Mod of your thermostat housing reqd)
Bosch 3 Wire wide band Sensor
Four Fuel Injectors ( 20lb / 3Bar / 14.3 OHM )
Fuel Rail
AN Fittings - (2) AN6 and (1) AN8

The Ignition side :

Distributor ( Setup for Wasted spark with a 12-1 shutter)
Wasted Spark Coil
ICM ( Ignition Control Module)

ECU:

kptronics.gr custom made ECU for our application
Complete wiring harness
Harness terminated at the ECU and at the sensors
( Roughly 4-6 wires to hook up )
Base Opel CIH tune prebaked into the computer (Optional performance tune available )
Bluetooth connectivity to the ECU

All you should need is a fuel system to the rail ( Relay for Fuel pump in the computer ) and spark plug wires, and a modification to your thermostat housing

( Although thermostat housings are also something I am looking at making. )

We hope to making 10 of the complete kits..

Intake Kit with fuel rail and sensors and connectors, but without the ECU/Distrbutor will be $1790

We will have 10 high port and 10 low port intakes on this first run. That way IF we make a second run I have an idea of how many of each I need.

what is it?

 

[The Scifi Guy]

Yeah, I have no clue whatsoever what that is......

 

[GoinManta]

The bushing for the Distributor / Cam sensor

 

[GoinManta]

As you can see here, aligning the shutter will be pretty much full proof.. if you have it off even a "little" it would be at worse a fraction of a degree.. that the ECU can be adjusted for.

I am pairing these with :

A Bosch ICM

and a Bosch Wasted Spark Coil Pack

To go with the Speeduino ECU and Tuner Studio.

Technically this could be run stand alone with a Sidedrafts.

That would be $600 for the sensor, the ICM and the coil pack, and harness.

 

[GoinManta]

The caps are done.. may have a test distributor together in a month or less at this rate.

 

[GoinManta]

The Kit.. as it is being produced

 

[The Scifi Guy]

My suggestion to update your logo looks good!

 

[GoinManta]

Too late for the Distributor cap.. But it worked good on it. Just next batch will say EFI and not MPI.

Here is a blow up of all the parts I designed and am having fabricated.

To say the least I am nervous, especially the shutter parts.

FWIW we got the 10 orders counting my 3.

Current orders

QT - 1H_F
PB - 1H_I
JJ-FT - 1H_C
*GM - 1H_C

*GM - 1L_F
JP - 1L_F

Does this mean the goin mpi ones will be like irmscher valve cover money in30 years when we're all gone?

Does this mean the goin mpi ones will be like irmscher valve cover money in30 years when we're all gone?

Well it will defintely be a signature of the first set.

I was thinking of removing the MAP Sensor from the intake.. BUT if it fails on the ECU Board.. its harder to replace. So keeping it.

NOW you've got my attention!

Can you tell me more about this option. What's included and what do I need to do?

 

[GoinManta]

It will include all this..

Along with a coil with the plugs to wire wasted spark coil.
