It's looks interesting.

If something is worth doing, it's worth doing half of.

Yes. I like the idea.

In the 13's at last!.. Just

You've gone and done it now.

You are likely to crash the tm server when the SC naysayers arrive!

Haha!

Nicely done, should open a few doors. One thing though.....(without trying to be negative )

Cost to gain?

Very interesting. Not a massive jump for SC as they already have an ECU that is for Diesel engines. And direct injection is basically a diesel injector plus a spark plug.

looks intresting

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!

If anyone can do it I'm sure JK can, I've seen his work on diesels.

It's probably an easier way of getting the dis-similar amounts of fuel into the inner and outer cylinders which charge robbing requires (charge robbing is the air really, not the fuel, so fuel just needs to be sent to match the air) rather than messing about with injection timing and different pulse widths which some of us do with port injection but, as Colin implies, I can't see it being cheap.

Direct injection uses very high pressures.

Schrödinger's cat - so which one am I ???

my thoughts exactley as Ben H
SC keeps coming up with some ideas ?

i seem to remember its significantly more det proof than normal induction.

anyway fuck that shit, ditch the throttle skim the fuck out that head, bolt a big VNT on and squirt some derv in there!

These days I reckon I could get perfect fuel distribution with a wet manifold setup

It's interesting but at £3200, it's a bit expensive. And it is annoying that they mention that this is the only way to get perfect fuel distribution (that's probably the only way _they_ know how).

I wonder if they're going to allow different fueling to account for the different VE between inner and outer cylinders. They probably do have per cylinder trim.

And frank technical discussions is not the same as being a naysayer.

I dont really understand why the company that did so much work offering an affordable 16 valve/8 port conversion cares about making the 5 port work!

That is cool!!!

I think though, that the winning strategy is to DI and wet port to keep the stuff clean.

I'm just pleased that they now acknowledge that the best way to injection the 5 port is to introduce the correct amount of fuel directly into the cylinder. Albeit using a more sophisticated method.

After all, that was what most of the "nay-saying" was about.

Anything that maintains 5 port development is good in my book. Chapeau.

Cost doesn't matter to some people. I bet credit cards are coming out of wallets already.

I have to agree with Jean, it is a bit disengenous to say they will "make history" to eliminate charge robbing.

The first commercial company to offer a bespoke aftermarket solution, I would agree.

Cutting edge technology (for aftermarket GDI) that has the potential to do it most effectively, I would agree.

But certainly not the first - notwithstanding what a few of us do it on this forum with offset injection timings and/or differing VE tables, even Rover did a pretty good job with the MPI MEMS.

I can't find much technical detail (I'm not registered with Facebook so may be missing a lot and I can't find any real detail on their website) but I hope they will be using widebands to show they have got it right.

The "naysaying" refered to I suspect is when JK suggested EGT data on a 5 port was an adequate indication of lack of charge robbing when two of us had both EGT and wideband data that showed otherwise.

But, like Paul, I'm all for continued development with 5 port heads and it's good to see people/companies like JK/SC pushing the boundaries.

And Paul is right, there will be people queuing up to buy this even before it's finished/proven.

maybe they will drill another hole to let the air in and remove the inlet valve.

This could be awesome, but i'd like to see the graphs... Using same engine, carb vs. SC port injection vs. SC direct injection at least. If he can get 150BHP NA, that will turn heads.

£3200 - that's a lot. Aside from the ECU, what do you reckon is the cost of the off-the-shelf hardware, the bespoke parts, and the machining?

I bet those injectors are not cheap.

Wont be long before you can rob all the parts off a scrap fiesta/focus tho! Just need an ecu.
