I am interested in the kit and I might do a custom kit for cheap.
Can you tell me what type of oil pump that they use?]



Also where can I get one from?


Thank you,
Shane

 

The hard part is finding a pump that will handle 300 - 350 deg F fluid temperatures, so a fuel pump is out of the question.

Check with some turbo streetbike companies like Mr.Turbo and Dr.Turbo. Most bike turbos require an electric oil pump since the turbo is mounted below the oil level in the crankcase.

Hi,
Doesnt the NEW corvettes use an electric oil pump to pump oil to the transmition cooler?

Can I use on of them>?

 

Sounds promising.

 

I was thinking of doing the same thing, and when I get the money together I am going to get this pump.

Fuel pumps WILL work - on the advise from some guys that daily drive their turbo cars on turbomustangs.com, I used a Holley red pump for oil return... didn't have any problems with it (I even went on a 190 mile drive the day after installing it!). If it does go out, replacements are cheap and plentiful.

A better solution would be the Tilton differential pump (someone posted a link to an identical pump in this thread)... it's about $250 to $300, last time I checked.

 

I really doubt that fuel pumps are good for 300 degree fluid temperatures for extended periods of time. Many of the rubber materials will harden and leak over time at high temperatures.

There's no guarantee they'll work reliably because the manufacturer never intended them to be used in that service.

That's just my 2 cents, take it or leave it.

Since there are pumps available that ARE made for hot oil service, then why not get one?

I've done a couple of trips between Austin and Houston (~3hrs, 190 miles), and had no leaks or other problems. Several people on turbomustangs.com use them on their turbo setups w/o a hitch as well. They do work, and yes, there are no guarantees, but at close to 1/10th the price, who cares?

I thought that was obvious - oil circulation pumps are $300. Freshly rebuilt red pumps are $35. You call yourself an engineer, yet the idea of using something for an application other than it's intended use appalls you? How odd...

 

Do you think that just maybe, perhaps, by some stretch of the imagination, there is a REASON the oil circulation pumps are so expensive? Could it possibly be that they use more expensive materials that are better suited to high temperatures?

I happen to be a pump engineer and I can tell you that the design of pumps that run 300 degrees is vastly different from those that run at 100 degrees. But then again, long-term reliability is a very high priority in my job.

I don't have a problem with using something for a different purpose than intended, but only after analysis. That's what engineers do. In this case, analysis would point towards "no" because of the problems that the cheap materials of construction may cause.

Maybe they are pricey because they are intended to pump thick 100w diff lube? To be honest, I'm not sure what makes them so expensive, but seeing as there is a $35 solution that has worked for serveral people w/o problems, AND is completely rebuildable, I really don't care what makes diff circulation pump expensive. Remember, we're not talking about a crucial passanger plane component; in fact, we're not even talking about a component that would leave you stranded. Worst case, the turbo smokes on the way home.

 

I think the turbo smoking is worth more than 300 dollars... personally, I would do it right the first time so I wouldn't be thinking every time I drove about the possibilities of what could break.

 

Did any one look at my post above? This pump is both designed for oil and high temp rated to 300*. It does cost $185, not $300, but I think it is well worth it from a reliability stand point.

Sorry if I sound bitter, but I spent alot of time researching the best pump with reliablility and price in mind, and it is hard for me to accept that I could possibly use a $35 rebuilt fuel pump to do what I need it to do. I feel like I might have wasted my time researching this, but as far as getting something that is designed to do the job and is not a killer on the pocket I feel I will still use the Mocal, if money is tight at fab time I may just put the red pump on untill I can afford the Mocal.

As far as smoking the turbo goes that will kill the bearings and other things within the turbo quickly.

 

If I had found one for $185, I probably would have gone that route myself... the only circulation pump I had found was the Tilton, and was much more than that. Still, I have no regrets - no problems, and the $35 pump has done fine (regardless of the doomsayers)

BTW, you could stand to learn a little more about turbos! You strike me as knowing nothing about them ... Smoking has NOTHING to do with the bearings. Inside the turbo, there are two shaft bearings, a thrust bearing, and seals on each side of the shaft (one on the exhaust and one on the compressor side). The ONLY thing you risk is potentially blowing out the couple dollar compressor side seal (even then, as long as the oil pressure isn't very high to the turbo, the seal should be ok after changing the pump out) - the exhaust seal is basically indestructable.

 

EddieP,

You are correct I am not an authority on turbos, and I don't claim to be, but I do know what I read and I can send you to the site I got my information from and I will quote them.

"There won't be any tell-tale blue smoke foretelling of turbo bearing demise or "coking" of the oil resulting in spun exhaust shaft seals."

Writen in context to the reason they use a "Positive oil scavenging system", IE. oil pump.

That was writen on a page about turbo BMW motorcycles.

I don't just say things for the hell of it, I do read it or know information before I speak.

 

Slow-Thanks for the education.
