Transaxle oil cooler pumps Options

[pcar916]

How many of you are using gear pumps instead of diaphragm types and what filter element (micron) sizes are you using?

[pcar916]

I thought I'd follow up with a summary of the approximate cooling system costs. This assumes you don't have any of this stuff lying about and that , instead of a diaphragm pump, you choose a mid-range gear pump with a catch can etc.

Pricing for hose fittings from Racer Wholesale Parts:
1. Cooler $ 90
2. Fan $ 70
3. Pump $275
4. Filter $ 75
5. Chk valve (1.2lb) $ 40
6. Fittings (-8AN) $308 (mandrel-bent except the vent system)
7. Hose (-8) $ 70
8. Catch can $ 70 (unless you make your own... I did)
9. Controller $ 30

Roughed out it'll be: $ 1,028

Someone out there is going to do this. For some reason I just can't get any new system into Penelope without spending $1,000. (IMG:style_emoticons/default/beerchug.gif)

Hey Pcar916,

I see that you have been working over the whole issue of trans cooling very diligently, but am left with ONE basic question: do you have empirical DATA so you KNOW your trans oil temp will run TOO HOT and that you MUST have an oil cooling system?

You could find, as I did, that all that extra hardware is just NOT necessary.

Best,
Terry

... do you have empirical DATA so you KNOW your trans oil temp will run TOO HOT and that you MUST have an oil cooling system? You could find, as I did, that all that extra hardware is just NOT necessary.

I MUST. As I put in an earlier post temps on the track can never be less than 210 because that's the temp measured on the street in the early summer in relatively cool weather (for here). It's never going to be lower than that at the track but will certainly be higher, especially in the late summer. It's true I haven't measured it on the track, but this transaxle will never see hp and torque lower than this 3.6L delivers.

Since I'm building a filtration system anyway the extra cost is for a cooler, fan and the associated hose and fittings. I'm willing to go there knowing I'm squirting cooler oil on my R&P. I like 180-200 for an operating temp. If I could get the return oil to the 150 you see in your machine I'd be delighted. How are you measuring it?

Now, if I lived in Alaska we probably wouldn't be having this conversation... (IMG:style_emoticons/default/beerchug.gif)
