How will this affect carb users? As I wasn't planning on injection were I to get one of these!

[OfMini&Men]

putting the injectors right where the inlet ports are might help quite alot, the MPI manifold was best manifold rover ever designed for the mini.

 

you want to pop on turbo mini's those lads know alot about forced induction and running injection

[podifold]

We'll have to wait and see with regard to carbs. I've spoken to HUBBA.HUBBA about this and he's going to carry on with his installation. He's in a good position to test it having converted from a running suck through set-up.
 
I got the new casting back this week and got it machined up today.  Very happy with how it turned out. There's plenty of room at the back for the injectors in their new position.
 
I'm hoping to get it all back together this week and back on the dyno as soon as possible.

I wonder how the heat is going to effect the fuel won't one runner be a lot hotter than the other?

Where is your wide band located?

[OfMini&Men]

New casting looks a bit more promising to run with Injection now, looks near enough same distance away from the ports as SC 5 port efi kit effectively making a WET manifold system.

 

But If I was you, I'd be making a heat shield to sit under the manifold and then either have the Exhaust manifold Ceramic coated or at least wrapped just to help in that area with the heat soak.

Following this very closely, definitely thinking of purchasing if it provides better power than suck through setups.

Whats the progress on this?  I saw this picture on instagram and it looks like things have changed a lot...

Looks like hes cracked it now (Y)

 

 

Blow through supercharged set ups are a nightmare but good on Podifold to keep at it (y)

If the kit is complete and looks like that, I may be tempted!

Yup, big changes here at Podifold HQ.

 

I'm working on a new manifold that mounts a 52mm throttle body to the intake side of the supercharger and, along with some modifications to the existing manifold, allows the use of a stock BMW Mini by-pass valve in place of a dump valve.

 

The new configuration is as near as possible identical to how BMW did things. The reasons are:

 

1. Smoother running. Without going into a long explanation theres an issue running an atmospheric dump valve with the current fuel injected system that causes the engine to momentarily run lean when the throttle is increased (n.b. this wouldn't be a problem with the carb set-up though).
2. Supercharger whine's awesome until it's your daily drive and it's screaming at you constantly on the motorway! I'm hoping this'll quieten it down a bit.
3. I can do away with the ridiculous bonnet bulge I have at the moment for the air filter.
4. The new manifold and throttle body combination allows an IACV (Intake Air Control Valve) to be fitted to help with cold starts and maintaining a steady idle.

Things are going really well but the design's already changed slightly from that last picture as the throttle body/air filter need to be mounted even lower to clear a standard bonnet. Coming up with a complete package that'll fit in a round nose without any major bodywork or ancillary changes has always been the biggest challenge.

It's a good point that I don't really know how to answer. Unfortunately I've just got the one wideband sensor located after the y-piece under the floor so gets the combined AFR of all four cylinders. Sparks plugs are fairly consistant across all four when removed though.

I've managed to source a few components lately that might mean I can supply this as more of a complete kit than just the manifolds if that's what people want.

[Jared Mk3]

Any change in casting for carb use? It's very tempting.

[podifold]

Not exactly. 

 

The raw casting as it comes back from the foundry has provisions for both carb and injection use. How it's then machined determines it's final use. So for carb users, although the main casting will look slightly different now, it still functions in exactly the same way.

 

I'm still waiting to find out how well it performs with a carb though.

 

As a side note, a carb manifold could be converted to an injection manifold at a later date, but not the other way around. All will be revealed soon.

[Steve220]

As a potential customer, I'd be more interested in a kit than just a manifold.
