Mini 7 Port Heads

i'm probably behind, but just recieved this link from minisport...

my life would be complete with one of these

Holy smack! £1K!!! But a lovely design, no?!?! Looks like it's a design begging for fuel injection! Yeah, baby!

Now, THAT would be a fantastic Turbo Mini!!! I'm getting chills just thinking about it...

We can tell, you must have used up your annual quota of exclamation marks in that one reply!
Read about these a couple of MW's ago, look cool..

WOW, looks like some serious potential there:)

Whoa, yeah, sorry Alex. I got a little excited. Got my lithium, though, and the exclamation marks are a thing of the past...

And the £1k was the low end of the price range they are shooting for. £1250 is the upper end. But who knows where it will stabilize...

Ben H, when you're not made of money, it seems like a lot of money. But I know that the Arden 8-ports go for much more, used, so in comparison, it is a bargain, I guess.

Sure would love one to set up for FI. Having timing and fuel fully mappable would be awesome. (see, no excitability this time)

Ahw, I quite liked the enthusiasm

They were cheaper when bought direct from AKM. Such is life.

maybe if i ask father christmas nicely and be good all year i can get one

They were cheaper when they came from AKM because he just sold a blank casting and there was a lot of work to be done to make it work on your particular application. Minisport are selling a complete head, supposedly made for your application. It looks like they have done more development on the head that has been done before so I think that the price reflrcts that. I am not a huge fan of minisport, but this looks like a good product.

Its half the price of a KAD 16v head and you can still use normal cam, rockers, exhaust manifold (LCB, whatever). This is great because it is much cheaper to find out which bits work or don't without having to buy expensive specilist parts.

Myself and Wil have been putting money away for one of these heads, but with recent events it looks like it will be a while before we can afford one, unless I manage to get a few months working on an oil rig, but the common law bread knife is not to keen on that..........

I agree that they are a bargain (although not cheap), however Ben, you are wrong about the price.

Minisport say:

"Unfortunately, we are unable to give any accurate prices at the moment, but envisage the price for a standard BARE 7 port head to be inline with the AKM price of approximately £1000 to £1200 + vat"

So it'll be more like £1500 for a complete head. But when you think that a 'good' 5-port head could cost a grand then it's not so bad.

has anyone actually read about the heads ? seems people think its a bolt on part, minisport say that was tested with great success by vizard but if you read the article he says the ports are to big, and that it really only worked well on bigg cc engines with scatter cam and good atomization of fuel, also no one says that you are still looking at 3k after buying the throttle bodies ect ect

turbo'ing a 7 port sounds great yeah throttle bodies look great but has anyone tried to use throttle bodies on a turbocharged car before ? i doubt it! thats why ALl road going turbos have 1 body with 1 burrerfly and a custom plenum and injection for the application, using throttle bodies with a turbo = crap drivability, i had a long chat with omex last year when i was going to buy one from AKM

the ONLY reason for buying this head on a turbo application is IMHO for show as you wont see anymore power from it over a 5 port carb turbo again IMHO

Nissan Sunny GTI-R uses throttle bodies as standard.

well, you will at least be able to do a fully EFI turbo with that head, no charge stealing etc

A turbo enging is comparable to a big cc engine though, so the large ports become less of an issue.

The crossflow design of the head will surely be of some advantage over a 5 port.

I agree about the throttle bodies though, a single body with a turbo is the way to go. This solution would be possible using this head so no worries. Also, with the Megasquirt and scrapyards the fuel injetion is quite cheap if you do it yourself, and we already use the ECU.

As above though, we've shelved the plans at the moment. Although Ben has had a much crazier idea which might make an apperance on the TT2.

in my oppinion the 7 porter on a turbo application is useless!

the turbo would overcome any flow problems on a 5 porter (2 inlets) modified correctley

the three exaust ports remain the same on the 7 porter as the 5 porter no real gains there!

if it were say a 4 port exaust

things would be a little diffrent in turbo terms

with the extra port, it would help matters by the easyer flow of gasses not having to share the centre exaust port and would spin the turbo up slightley quicker!

just my oppinion!

4 exhausts - twin turbo :)

I agree with Ben...

Why do you need 7 ports?

Fuel Economy?
Emissions?

Not normally things people care about on minis too much LOL.

The reason I say this is that I'm sure no one is really after more power than you can get with the 5 port head are they? In all honestly??

There still the fact you need a serious bottom end to deal with high power and the same is true for the gearbox. As the 5 port will do 200 bhp and become fairly undriveable... how much more power do you want>?!?!?!

i'd like one just for the bling factor

I would buy a 7 port head as it would allow you to install injection and make it work PROPERLY.
This would probably not make much more power than a 5 porter on an SU but would (I think) be more tractable, have no hot start problems etc etc.

My 8 port with a 296 cam was really nice to drive (until I fiddled with the final drive). Smooth idle and strong pull from low down and a fair bit of top end with that cam. I would expect the 7 port would be able to give similar characteristics, with the advantage of not having to spend £250 on an exhaust manifold.

On the bling note, I have been to a show, removed my bonnet, started the engine and seen people actually run across the car park to look at the car. Mad :)

Being able to easilly run efi - and get rid of the restictor in the carburettor mouth, and the last little piece of charge stealling that still occurs with an SU will net a power gain I reckon. £1500 + worth though, I'm not sure!!!!
