Ignition mapping, getting the basics.
Turbo Mini Forums

yes ,taking money /time into account , just changing to a mapped ignition would maybe get 80 % of the gains - estimated untill back to back test carried out - compared to fuel and ignition ecu, i'm in a lucky posistion to be able to throw some time and money at it and write it off against my business,
a wet manifold is definately the easiest way to achieve efi , and charge robbing could be eliminated by direct injecting, maybe through sparkplug area - its mostly solid , maybe enough room for small m8 thread spark plug and direct injector ?-
aftermarket fuel injectionon minis turbo or atmo is early days but it can only get better!

I'm still waiting till I get a 7-port head, that way injection is easy.

Also it will be a a vast improvement over my standard 12g940 I run at the moment.

Fastest 998 mini in the world? 13.05 1/4 mile 106mph

i've had an email from Jenvey..

"The problem with the mini is the siamised ports because it robs the fuel from the other port. The way some of our customers do it is by injecting the fuel less but more often. This creates a wet style manifold. As far as I know no one has jet got a good system working on a mini.

I would try using a pair of SF throttle bodies on an old twin SU manifold as I feel that would give the best chance of working. I would then use 2 SF throttle bodies of 40-45mm bore with a pair of 45x90 airhorns."

I've also had a suggestion to use a BMW KC1100 head instead! How the hell will that fit!

re the bike head, have a search for a user called "madmatt" or similar on miniowners and the 16vminiclub. believe hes got a site with details of the conversion :)

Uh, sorry, not meaning to spoil the party, but is there anyone that can give me an answer in the initial question? In numbers?
Thanks,

(y sorry for the hijack, but a good thread all the same)

i had the displeasure of reading miniworld in whsmiths this week, minisport (groan) are selling that akm 7port head now

i may take one off their hands in a couple of years time, then my car would be complete

edit: oh i forgot to say this would be ideal for the injection system, and you can still use your current manifold

Sorry to butt in on another topic I have no idea about. One of the things I'm very interested in is head design and cam timing. I suppose that the N/A cam is bad enough for not considering the inlet port/flow behaviour, from theory, I would expect a more dense charge to have greater inertia. If EFi in 5 ports is a problem (Good article on the problems somewhere on the web by Marcel Chichac (sp?)) he was talking about using different cam timings to optimise the peculiarities of siamese inlets. I reckon the cam changes (which are outlined in Vizard) are worth considering for a forced induction engine. When I can be bothered, I'll come up with a proper explanation.

By the way, has anyone seen the new cam advertised in the mini magazines (can't remember who makes it) but it goes on about increased exhaust duration. Appears to be a nice compromise between the MG and the Ph2 cam.

Bugger off, I'm getting there.

do you mean the swifttune SW5?
