Yes correct...

main advantage would be the less thermal gradient...

Hi,

two_OH_five, can you send me your e-mail adress

Wolf_Tm, i have the cooler in the "transmission oil system", only as gearbox cooler
a other question, is it possible that you have TTE ST205 documents like my explosion pictures with part number etc.?

I think DJ did this and I pointed out that with this setup there is no opposition to flow i.e. no pressure, and so the true flow of the pump in the engine cannt be calculated, unless you put in all the oppositions to flow e.g. Block, head, radiator, thermostat etc

I think I have his calculations somewhere if this would be useful?

Edit...
Great to see some forward thinking by people! A bit of research is always a good thing!

Turbocharging - the replacement for displacement

Yes, I do know that is there, but:
- it would be quite a BIG exchanger, just for transmission...
- I do know they use a engine oil/water exchanger
- in the parts list file, the AM 65779 cooler is listed as "engine/gearbox" heat exchanger

So...



ST205 (207f) and Corolla (260f)? Yes

Hi

Kris, i can't can measure the true flow through the engine like you said, i do the test simple with the same conditions and calculate how much percentage the flow raise -> we will see the result

Wolf, do you want to send me the data?

Hi,

yes, from Corolla, but not from the ST205

Hi,

today i got the pump-housing back from machining

-2mm should give a axial-clearance of 0,5mm

and then he told me that he also machined the back side to become a correct seat in the machine
problem: the o-ring....i hope that all is ok without any leaks

Are you planning on testing this to see what difference the reduced clearance makes to the flow rates?

Hi,

Don, correct
less axial-clearance = less flow from the pressure side back to the intake side of the pump (efficiency)

and here is the result:

the pump do actual 7,9L/min which means +1,5L/min against 6,4L/min OEM spec

a plus of 23% -> job done

be warned, tighten the screws carefull, i destroyed one thread as the wall of the pump housing is thin against OEM
