Who's actually got this running on a 5 port???

The typhoon Ecu is listed at sequential

Even with an ECU that can support a fully sequential injection setup, you still need to have the correct intake setup to use it. And you also want to have the possibility of using injection timing done with respect to the middle of the injection pulse.

As for the Canems mentioned previously, it can't do sequential injection. It only supports semi-sequential injection and this has been proven to be inadequate to deal with charge robbing because you can't change the fueling between the inner and outer cylinders.

For what its worth: the Lumenition 460 is listed as semi-sequential, and the DTA 48 is staged or Switchable

Yes you guys are correct here, I've only been running the car at over 200+ bhp for 6 months of hard testing and tuning, I guess the rushing into it and doing short cuts doesn't pay off, o well he he! he sayd=s with all pistons still looking as good as new!! Still If i only know what i was doing thing how much better it would be. omg!

Best 1/4 mile 13.2 seconds @116 mph
First 5 port miniturbo to make over 200 bhp on a carb?

How long before the world's petroleum supply run out?

Nic are you thinking of an 12 sec EV build?

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

personally imo you can theorycraft around this if you have years to waste or you can and i quote

Mine runs fine non sequential, no idea on power as I've not had it on a dyno I'd trust to quote a figure, but its a lot. No failures yet, I just run a slightly rich mixture to avoid weak on "robbed" cylinders. How do I avoid making less power? Easy - run a fraction more boost and waste a tiny bit of fuel. Water injection isn't really doing anything at the moment as I've not run more than 20psi and I've not pushed the ignition timing to the edge yet.

More when its strapped in the back of the blitz (in progress).. mmm rear wheel drive..

im very intrested in running it the same configuration as Andy but its the other bits I need it to switch at boost that SC have said it doesnt do in the software which is a shame. It would knock my pikey WI and boost pressure bypass valve.....

plus all of the wiring, injection pump, tanks and regulator setup.. all a bit of a PITA.
Plus you have to stop speding somewhere or the wife is going to leave and I havent even breached the fact I want a new gearbox over the winter....

no idea, I have just been looking at the conversion myself and perusing the specs online.

I just want to say that monitoring fueling on each cylinder, and using fuel trim to equalize it, is a known way to maximize power on any engine. I've sold kits that allowed AFR monitoring on V8 engines and that has allowed to make measurable power gains on a dyno by trimming the fueling and injection timimg.

So as opposed to what some say here, it is not questionable that using a wet wall setup, not monitoring AFR and not compensating for it leads to a non-optimal setup. It can be questioned how much non-optimal that is and if the cost/effort is worth it but don't talk out of your ass if you don't have the data to back it up.

It's not "optimal" but it "works" and that isn't talking out of my ass, and bollocks to you for suggesting so.

Just because we are not on a crusade to get the most out of every cc of fuel and every lb of air doesn't mean it's not a perfectly viable and simple solution.

Did I mention bollocks.

talking of bollocks, looking at Jimsters Avitar he has a great pair of "top" bollocks... Im surprised you can sleep at night with them.

Off we go again :( The flame is lit, so we may as well have a good row.

When I first joined this forum about 6-7 years ago, the opinion of the self proclaimed experts in 5 port injection at the time were very strongly aginst the use of wet manifold injection for use with a turbo. The threads are all here if you care to look. The reasoning was that the fuel distribution was just not satisfactory. The general consensus was that the only way was to use port injection but there were problems due to the lack of ECUs that could do injection timing. This all follows on from the work done by Marcel Chichak some years earlier.

As I had grown sick of the sight of SU needles back in the 80s, the only way that I was prepared to go forward was with port injection. So I built a test engine with dual widebands and a carb and started testing. After a carb I tried crude untimed port injection and finally various combinations of timed port injection. After thousands of miles and dozens of data logs we got a working system that can be tuned to give sufficiently accurate fuel distribution for use with a turbo. All these tests were documented on here.

In doing all these tests and trying different ideas I learnt a lot about what was necessary to get a SAFE fuel distribution, not perfection but safe and this is the main point here. Boost and lean mixtures will damage an engine. Getting enough fuel into the outer cylinders on the 5 port is challenging due to port robbing and wall wetting. Arbituary injection just does not cut the mustard. You may see 13:1 on a single wideband but you may be running 15:1 and 11:1 on the outers and inners respectively.

Now several years on with a lot more tangible evidence of the problems and my opinion has not changed. Wet manifold is no better than a carb and is potentially more damaging. You may say that we are crusading for port injection but my main concern is you youngsters spending all your spare cash on an engine and then putting it at risk.

I congratulate Matt on getting a system working, but as he points out, it is no better than a carb and takes a lot of fiddling to get right. Dual widebands would make setup a lot easier.

Choose whichever system that suits you, but be aware of the limitations and potential risks.

Sorry for the essay, but hopefully a lot of you relative newcomers will benefit from the histrory.

For me, I've had a summer off from Minis and am unlikley to come back as they have fallen right down my list of interests. I'll help and support my lads if they want to continue but I can't be arsed anymore.

Don't fancy completing the siamese injection kit you mentioned some time back then?
