Turbo oil pumps
Turbo Mini Forums

Hi folks!

There is some information on oil pumps I collected because of (fab's) interest and my disappointment of a "hand selected" Turbo oil pump from a big Miniparts supplier:

Oil Pump Comparison:
Or. Turbo Superflow Minispeed MSC MSC
(Avonbar)

Type Turbo Turbo Turbo Non Turbo Non Turbo
Rotor Dia 44mm 56mm 57mm 55mm 52mm
Rot Height 21mm 18mm 18mm 14mm 14mm
Back plate Alu Steel Alu Steel Alu

I aslo made some pictures of the pumps and send them to Dave to make a comment on their design. My impression on the Powerflow pump design was very good.
I can't support data from the MSC Turbo oil pump at the moment, because it went into my waste bin after "testing " it in my engine.
I think Dave could help out here with his engineer knowledge to enlighten the topic?!
I can't post pictures; maybe Dave will.
Cheers
Harry

PS: Take care of the heart of your engine!

Jim , picies are in your mail;
harry's work shown that mety turbo genuine oil pump have good casting/machining but 44 mm rotor diameter and 21 mm larger/ instead of 59 mm for the minispare , and 58 for the powerflow /avonbar selled one ,
the fact is that ater been looked by dave and Harry ( green throuser............. :) ,ouarfffffff sorry dave) show lot of play and bad casting on the Ms oil pump, and good play , good casting for teh poweflow one, mainly because te power one have an anti pulse groove and better machining /casting finished by hand , as NOT the MS ones

Nice pics people:) I had noticed that the standard item was different to the other pump we all buy.

Best 1/4 mile 13.2 seconds @116 mph
First 5 port miniturbo to make over 200 bhp on a carb?
First 5 port miniturbo to make over 200 bhp on Injection?

The first pump, on the left, that is the org metro turbo, is that a rubber o ring around the outside? if so interestign how none of the new pumps have this

Team www.sheepspeed.com Racing

Yes, the origin Metty Turbo pump has a rubber seal. Nice detail! I also didn't notice that there are so many differences in pump design until I had a closer look.

we can "tell " that the powerflow one is an improved mety turbo item , good quality , casting debured, (no grit inside, don't laugh some others "hand sellected" oil pumps can have .....), it have an improved rotor diameter, which will not increase the pressure , but will increase the oil flow ( gpm), with less pulse effect, harry also point that it have a little passage between the two side of the pump (pump and pressure one), this after Dave analisys is to reduce the pulse effect of the pump and show a very well designed , thinked, oil pump. my last OWN words are :
this is far from the ms turbo oil pump design, with undebured casting, which can sometimes have (not intel inside) but GRIT inside , and out of play tolerance new from the box.
thanks guys to help finding a good source of HEARTS/ blood pumps, for hour pricey lumps.

Don't know what more to add, Harry and Fab have done a good job here. My 'old' minispares pump (about 4500 miles) is scrap as far asi'm concerned, far too much play in it.
The Avonbar one is a well thought out, and developed pump, just like the original HolburnEaton (HE) pump was. The only downside is the weight of it - a 1/4" thick steel backplate is the cause...

in somery then which pump, from whom and how much is recomended... :)

turbo 16v k-series 11.9@118.9 :)

Sorry evo , can't make more pub, just read the trhead.you'll easily understand which are the best pumps and where to get 'em.

wasnt for me, i got the jist of it, was jsut thinking more along the lines of for an FAQ type thing. Question(ish) at start, outcome at end. nm :)

turbo 16v k-series 11.9@118.9 :)

Denis O'Brien.

Put it this way - the only pumps i would purchase are the Holburn-Eaton (HE) pump, or the Avonbar one. The 'pukka' HE pump is no longer available.....
