fuel pump and ultralight flywheel
Turbo Mini Forums

im looking at the minisport ultralight flywheel. i will be using a pre verto clutch setup. can anyone advise whether an ultralight flywheel will be suitable for a road car? i have a cooper mpi for my every day car, so its not as if il be stuck in a lot of traffic in the turbo

rough engine spec is 1300 bottom end, swiftune cam, running 10psi.

will be aiming for 120ish bhp. will the ultralight flywheel maintain tickover or am i asking for troubble with such a flywheel?

also, does anyone advise facet fast road fuel pump? will be using an spi tank (and old cooper s right hand).

advice apreciated, cheers

also using grey diaphragm, standard pressure plate and ap fast road clutch plate. cheers

judging by the fact you said your running 10psi i guess your going to use a sucker or blower. not sure on a sucker but on a blower a facet fast raod pump will not be high neough pressure for a turbo set up to run right, keep the spi pump that should work better
i think im sure someone will correct me if im wrong

standard metro turbo t3. its a non injection car so not sure if i can retain original pump

spi pump will be fine for 10psi

a metro turbo fuel pump runs at three bar
im sure you need a pump that can run a minimum of 4 psi above the boost your running,
so a high pressure pump like a metro one can be adjusted down with the fuel pressure regulator it cant be adjuster to run at a higher pressure

i hope you have not forgot about the pistons and sorting your compression ration lower jack.

and please dont miss out an intercooler .......its free power and you can run more boost if the pistons will take it

so use the spi pump instead of facet?

how about the flywheel?will the engine tick over or will i have to adjust tickover to something stupid?

A turbo engine with a UL flywheel will idle perfecly at 1000rpm. It depends on camshaft of course, but it will with a Ph2 ie.

so guess thats the case for swiftune as well? cheers

I've got an ultralight flywheel, and really It doesn't seem much different to the standard one, in terms of pulling away, idling etc.

It does spin up quick though.

a facet pump WILL NOT work with a turbo unless its suck through.

Metro turbo arrangement, blow through, needs an injection style pump. An spi one will be fine for 10psi, an mpi one is better.

It makes a nice neat job of the install and means no new fuel lines etc.

You just then need a turbo fuel pressure regulator.

oh yeah and an ultralight will be fine. mine idles perfectly with a PH2 cam in it when it hasnt chewed a plug

and thats with 1.5 roller rockers.

cheers. a pressure regulator is one of the last things on my list. theres a guy on ebay selling them for £60 new i think, am thinking about posting a wanted ad here.
think i will go for the flywheel.running sw5 and forged lightened rockers bushed to 1.5
