Miglia Turbo
Turbo Mini Forums

looking forward to seeing it in action all being well

This is my favourite of all the minis Ive seen.
I have one question, Whats the story with the Individual coils? My dads Civic has the same set up, whats the benefits of it?

Thanks ciaran.

The advantage of the individual coils is that they are the simplest way of setting up the ignition on the MS3 or a sequential MS2. They have the ignitors built in, so you just have to connect up a logic level signal.

The other thing is that the particular GM coils are believed to be the most powerful OEM coils available.

Whether that actually relates to any power advantage in unknown.

The four coils weight about the same as an EDIS coil, so no problems there.

looking good!

yeah stick the bit in and give it a wobble

sorry to come after the battle but what about switching the TB side ?

Then you would have your cross flow IC engine bay ...

Rusty by nature

Breathers and fuel pipes in the way mate.

Probably not a good idea to put a car on a rolling road on the 13th of the month :(

All was going well, the car ran through the gears OK, we could see boost building, fueling was good, the staged injectors were coming in OK.

We were setting the injection timing at around 4k when things suddenly went pear shaped. The fuel pump could not provide sufficient flow for the injectors and fuel pressure was dropping off. The fuel pump was then very noisy so we aborted and came home.

Nothing obviously wrong with the fuel pump. No debris in the filter. Just not doing it's job.

The location of the pump is not ideal but it should work OK. In the coming weeks we are to re-configure the fuel system.

Good news is that is does what we expected to a point and the trailering was trouble free.

We will still make MitP tomorrow. We have filled the tank to the brim, cleaned out the filter so we shall have to see how it goes.

Don't expect much as we will be running a 3.5k rev limit.

Well, we took it to MitP at the Pod.

Sturgeo got to drive it up and down the pit road a few times. We logged each run and made adjustments to the fueling and all seemed OK.

Then he did a run with a bit more boost and it went very lean due to lack of fuel pressure. I was able to make the fuel pressure drop to 1 bar by just ragging it.

At the rear of the car, you can't hear the exhaust above the whine from the fuel pump.

So no runs up the strip but fun all the same. Sturgeo was getting out with a grin on his face :)

We're going to leave it for a while and have a rest before we re-jig the fuel system with a new pump.

Just tested the fuel flow after the fuel rails, then before the fuel rails, then after the filter in the boot.

I can piss faster than the pump can deliver :(

Just working out how to check the pipe between the pump and tank with a full tank

I had a look at this at mitp just before i met joe c, man does it look good :)

I must have walked right past it, bah!

amazing build, thats how a monster should look like.

There ain't no milling machine like the one at home !!!

Tricky to test the low pressure side.

Maybe feed the pump from a different tank. If it's the same you can rule out the feed. If better then investigate further.

Thanks guys.

Well, look what we found stuck in the pump suction:



It's the consistancy of tissue.

New tank, all new lines, filled from a new jerry can. We swilled the tank before fitting it as well.

Total mistery, but we cannot get it all out of the pump, so new pump required :(

Lesson learnt: fit a pre pump filter next time.

EDIT: it is a Walbro 255 after all, although I swear I bought a Facet injection pump

EDIT 2: and it was not there last week when i took the pump out to check the post pump filter. Must have been working along the suction pipe.

That's a bummer! Good to find a problem though so you cannot the issue to bed!

You may already know, but if you are fitting a pre pump filter make it 100micron not 30.

Paul,

I don't know if you are on oil for heating (maybe not as rural as me?) but if you are, just hook the pump up to your oil tank, recirculating from the bottom to the top, and the pump will be fine after a couple of hours.

And the small amount of crap will later be caught by the tank filter - there is a lot more crap I take out of my oil tank filter than that every year.....

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

Oh yes, we have no gas supply, but a 2500 litre oil tank. It's near empty and I'm bracing myself for the bill to fill it :(

I could just rig up the spare Miglia tank and half fill it with diesel.

Thanks Rod.

just half filled my 2000l one..... 51 ppl.

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

Ordered mine two days ago, best price I could get after playing them all off against each other was 51.40p/litre (for 1200 litres).

Heating oil and diesel are virtually the same, apart from the cost, a slightly different smell when you run an engine and (obviously) what Customs and Excise think about it when they sample the tank with a proper rig (not just the one that looks for red).

EDIT - anyway, back to the point, diesel or heating oil are very good at flushing out things like pumps without damage as they are very good lubricants in their own right. It's just that heating oil is less than half the price of diesel.

Apparently now is a good time to buy oil. We burn 2000 litres of oil, 3 tonnes of coal and about 2 cubic metres of wood each winter.

Big old houses with no cavity walls... less said the better.

Anyway, I'll rig something up and run the pump for a bit before I buy a new one.

slightly off topic,

Ive seen a 1500cc fiat have its sump filled with diesel to release some stuck rings, drop oil, fill with diesel, start and leave running for 15 mins, drop out the derv, refil with oil.
