best oil coolers ? help

roy'sz

I did some spirited driving with no cooler and ambient temp at 105 and it shot from 235 to 260. I got the cooler kit from nissan for $0 via nissan north america and installed for $0. I don't track my car but love me some canyon carving. After the kit being installed I filled the car up and went to my normal hills. I did a long run up the hill running about 95% and the oil never got hotter than 220. I came back from palm springs and again never hit over 220 and it was 109 out there. I need the thermo because of the cooler nights. Have heard from other experienced guys on here that it won't make too much of a difference at night when i go home with it being cooler i may have to block off some of the cooler.

Yeah, those are definitely good examples. With no cooler the oil get's too hot for any kind of aggressive driving. For most people who push it on the street, a smaller kit will work. For those looking to track their 370 at all, you need something more.

That's why we developed our own, because the other kits we tried didn't work on the track. But we daily drive our car as well and as such developed something that works on a daily basis too.

So what's the difference between your kit and the other on the market?

Casey@AEperformance

First big difference is the size of the core we utilize, which provides sufficient oil cooling for track use. Second big difference is the core design, which allows the oil to reach temp quickly without the use of a thermo adaptor, which makes the kit suitable for daily street use as well. Third big difference is the price, which is much higher, but is a result of the core needed to make our kit the most effective oil cooling solution for street and track use.

...Some other differences are in the amount of actual testing we do. We have driven with the kit more than 30K on the street with no issues of slow warm up or over cooling. We campaigned the car for the last season and a half of Time Attack as well. The oil never overheated, we went undefeated, set a new track record at each event and won the championship. Another example is that we also pre-assemble and pressure test each line to make sure they won't blow and in turn blow the car's motor. All of these things give us the confidence necessary to push the car and not worry about potential issues, which is how we want our customers to feel when they are pushing their car as well.

Oh hahahaha ok, but what about the exact opposite as far as cooler temps go? I am seeing 160 with no thermo and it being in the mid to high 60's. Have you compared your kit to a nissan kit?

ChrisSlicks

The oil temp warms up quickly if the car is not moving or if moving slowly, if you are driving at highway speeds it can take a while to get up to temperature. When I drove through Canada at the end of August last year the temp got stuck at 160F on the highway. The air was just too cool. For driving that time of year I think a thermostatic plate would be helpful, in the winter only a block off plate works.

Im lookin at 15min warmup time. I start my car at 1140 at night, change my shoes lock up my shop and when i come out my car is almost 160 depending on ambient temp. By the time I hit the highway my car is at 180 but cools down to the low 160's. So I guess I misunderstood why ae was sayin no need for a thermo. I also forgot most people don't work 3-midnight like i do. That is why im goin with the thermo but I have heard also of having to do a partial block off on the 34row.

ChrisSlicks

The thermostatic plate will allow 80-90% of the oil to bypass the cooler, but if it is cool enough then even running with just a 10% flow the core and still bring the oil temp down by a good margin (low flow rate but large temperature drop due to long time in cooler). In Riverside I think you should be okay with just a thermostatic plate added to the 34. If temps are regularly getting below 50F then you will definitely need a partial block off.

I thought there were quite a few tracking with 34R coolers with good results..

roy'sz

Hey chris thanx for the heads up on the temp below 50. It has been known to get cold here in the high desert part of riverside. I don't remember the lowest from last year but it will be interesting to see.

FL 4Motion

there are.

Ron

AE must have gotten a defective 34R cooler..

FL 4Motion

lol.

ChrisSlicks

I would think they are pushing a little harder than your average Joe.

IMO build your own kit... the parts are readily available and it is easy to do. You'll save a good amount by bargain shopping... I think I built my 25 row setrab (with a series 9 which is thicker than the standard 25 row setrabs) for just about 350. I did get a used cooler however but from Z1 or any other outfit it would have been over $500 with the 180 thermostat (which I believe we need due to cooler climate in NJ). I was also able to go with a longer hose setup for that price so that I had routing flexibility. I used the factory intake ducts which means I avoided putting any holes in any part of the car.
