Polestar Management
Turbo Mini Forums

Hi, When I was at London to Brighton I saw this Mini turbo, On "Polestar" management...

Anyone on here use it? Had any experience with it?

Looking at it as an option for me, As at the moment, Im collecting parts to turbo my MPi Mini but unsure If I should go down the Management route, Or SU carb?!

Lightweight racer coming soon.

Hi,
If you're going single point injection you can use just about any ecu.
I've not heard much about the Polestar, so from that I'd imagine info will be in short supply.
Compare every brand you can. Features / support / cost ....
VEMS seems like a good option to me....
Cheers,
Gavin :)

Is it easier to turbo a SPi car over a MPi car? If so then why is this?


Is it easy to convert to SPi??


Sorry for all the questions.. LOL

Thanks though

SPi in the sense that it uses one injector or two mid size injectors staged rather than the standard factory throttle body 'SPi'

Its not whether its SPi or MPi, its whether its port injection or wet manifold. Bat is reffering to the wet manifold in either a single or a staged injector set up, and currently the easiest to achieve with good results.

This is how the car in the above picture is running, wet manifold and it looks like a Jenvey throttle body, which could be a single or dual injector.

If using either an MPi or SPi car, the electrics and plumbing are pretty much of a muchness, but the MPi would be the better choice as the right fuel pump is already installed, thats not discounting the SPi if you change out the pump.

Again if converting either car to turbo, you would be ditching the inlet manifold (if you have the sense) off either car and using a standard SU manifold, again as you can see in the picture above.

Please every one note the sensable plumbing in of the water heated inlet manifold as well

Hope thats of some help

That makes sense! Thank you :)

If you run 2 large injectors? What cc is ideal?

and whats the recommended Throttle body size? Or if you didnt use the SU Manifold, Can the MPi manifold and TB be adapted?

Thanks again

The MPi manifold is port injection, and unless you are considering paying close to £900 for an ECU that has individual injector maps, it is currently not an option.

the use of staged injectors has been talked about already, there is a topic in the injection section of this forum, close to the top, have a read of that

two 600cc injectors would be good for 180bhp. Throttle size, if you consider some are achieving huge power figures with an SU 44mm throttle, then thre is no need to go huge, i'd be looking at no bigger than 48mm.

So, you reckon throttle body, and wet manifold would be better?

Don't want or need huge power...

120/140bhp will be fine :)

Hi,
As things stand right now, it's the best bet.
Work is underway for port injection with a modified code for the Mega Squirt ECU, but it's early days yet.
The wet manifold setup is almost a guaranteed success as your basically creating an electronically controlled carb.
We already know what results you get with a carb
If your car is currently MPi, the VEMS ECU has 1 of it's 2 connectors the same as the rover loom, so with some pin swapping it's not too hard to fit!
Cheers,
Gavin :)

What kinda price is VEMS?

Also, Is there many people who can actually use/map VEMS?

:)

Lightweight racer coming soon.

Also, Which one of these throttle bodies will be ok?

Twin injection > http://www.jenvey.co.uk/Imgs/Prods/SFE2_m.jpg

Single Injection > http://www.jenvey.co.uk/Imgs/Prods/SFS1_m.jpg

cheers :)

Twin injector would be your ticket. You should be able to use your MPi injectors.
Sprocket runs VEMS, I will eventually.
You just need a laptop to map it, any rolling road should be able to do the job for you.
You can set the ECU to learn the fuel map for itself. Ignition map would be a RR job I imagine.
A fully built ECU with wideband hardware built in is £330.
Take a look at If you go into the forum you'll find a load of mapping info here

So, the VEMS ECU will pretty much be ok on the standard MPi loom? bar a few pins that need changing?

As for mapping it, I know a few people in the trade, so hopefully they'll be fit enough to do it for me!

thanks again, Radleigh

Seems cheap too! I was expecting it to be alot more tbh.. :)
