I looking into turboing my y7 with a smaller turbo, keeping everything very simple. I will be using it for HPDE from time to time, is an oil cooler really necessary?

 

it's a nice extra i say, but not a necessity in my book.

HPDE'ing the car you will find out very soon if you need it or not. You'll either be overheating and need every mod possible to cool the car down, or you'll be fine.

Oil coolers aren't used that often honestly...if you can keep the coolant temps down, you will keep the oil temps down usually. I'd worry more about a good radiator, shroud, and fan before I'd even think about a oil cooler.

 

That's really more of a preference. HPDE events in which you are using a turbocharged honda could benefit from the additional cooling of the oil, considering it is the life blood of the turbocharger and is subject to additional heat stress since the system is under load for a longer amount of time than say in drag racing. I've race with one and without one, and I have found that IF you do race with one, make sure it is both properly located (not behind the intercooler, and if possible, avoid a full oil filter relocation kit. I found that they do keep those oil temps down significantly.

 

i would run an oil cooler if i was running the car hard for those periods of time, the cooler you can keep the oil the better it resists breaking down.

so what is a good location, any why not the relocation part?

 

Say no to Oil Coolers, it only adds another elements your oil pump will need to work harder for.

That is the reason for not using the relocation kit itself. Keep the oil cooler through the stock oil location. But the use of an oil cooler would be good for HPDE events, but the cooler needs to be placed in an open location (preferably next to the intercooler facing the open air)

 

There's not a lot of room for an oil cooler on most Honda's, but using radiator fan zipties you can put the relatively small cores up against the FRONT of the intercooler. They are thin enough that they won't affect much of the intercooler's cooling capabilities and obviously being up front will do a some good.

This is of course, if you can't find a suitable spot that does not block anything.

Easiest way to find out if you'll need an oil cooler is to log temps during a few HPDE events and see what they look like. If they're too high for your tastes, put one in.

i hate temperature! is measuring water temps any indication? I'm 205-218 F no matter what but thats logging on aem ems which is supposedly not accurate for water temp... 2k and it cant measure water temp

 

Honestly I'd run a heat exchanger before I'd run a oil cooler to greatly reduce coolant temps...You can get them with -6an inlets and outlets.

 

I track my itr which is making alot of power and before the cooler I saw oil temps of 300f. That's not uncommon either from what i've seen. Now I'm using a mocal sandwich adapter and push lock hose with 20'' x 7'' tube and fin heat exchanger and the temp never goes over 250f. The oil looks completely different after the day racing.

 

if you think about it, oil is more dense than coolant and it takes longer to heat up the oil. So in theory, once your oil is hot, you know your coolant is hotter. Your radiator will never keep up.

Having an oil cooler is like having an extra beer cooler. Though some oil coolers have check valves and can only installed for oil to flow a certain way, if what you're using doesn't, you'll want to make sure it doesn't back-flow in to your turbine housing.

wait, what?

 

Right up until you said HPDE I was going to say no.Sustained rpm really cooks the oil.Reliability on oil temps from 210-250 is not a problem but add another 20 or 30 and things go down hill fast.Even a cooler mounted horizontally low in the engine bay will get results.A lot of air gets moved in the front of the car and out the bottom of the engine bay.It's not as good as mounting in the grill area but it still works.As a rule of thumb 10-20 degrees above water temp is an acceptable level.

you like warm beer?

 

i mounted my oil cooler in front of my ac condensor above my intercooler

 

what about if you where to mount the oil cooler but instead of recurculating it back into the motor you use it as a breather and have the drop tube go down and out by the wheel? that's what my tuner recommended. what's your opinion

no, why? OK, allow me to be more specific:

can you explain this part please.

 

Out of curiosity, at what point would an oil temp be dangerously high? 230F?

I am about to attend an HPDE and want to keep a close eye on my temps. Been to quite a few with my JRSC but this will be the first with the GT3071R.

Thanks.

that means the oil isn't circulating back to the engine itself. It's not a catch can. Imagine the purpose of your intercooler, to lower intake air temps, but with a fluid instead of air.

get an oil temp gauge as you start out. About 320F on a sustained level, and you'll start to break the oil down.

If this is your first event, you'll probably be in beginner class, so the instructor won't have you hit the throttle as hard you think to start off. this also depends upon the track and driving style.

Well, if you have your oil cooler setup in a fashion that there isn't enough downflow, once the oil cooler fills up or in the event there is a clog, it could back flow in to your turbine housing. Most oil coolers that are mounted horizontally have check valves to prevent the oil from flowing back (vacuum pressure, etc). Those that don't have the check valves are typically mounted vertically (for gravity feed).

I was talking to another engine builder, and he mentioned that it should probably feed from the turbo, to the oil cooler, to filter, then back to the oil pan. He said it doesn't necessarily have to be in that order, but it should feed in to some type of filter before going back to the pan.

Is there enough pressure to run oil from a turbo through and filling up a oil cooler, than through a filter, and then draining back into the oil pan?

I thought the whole purpose of having the oil drain from the turbo going consistantly downward into the oil pan was because there isn't enough pressure and if the drain line went in a upward direction at any point, it would cause back up in the turbo?

Why not use the -3an line going for the turbo feed and dropping a small oil cooler BEFORE the turbo held down horizontally somehow in the engine bay, and then it would feed into another short -3 an line for turbo feed?

Honestly, I am a big believe in a heat exhanger for cars that see HPDE's....if you motor and coolant stay cooler, your oil will stay cooler. I've seen cars that overheated on 70 degree days consistantly.....completely stop overheating with the use of heatexchangers mounted behind the intercooler on the back part of the bumper support.
