Oil Cooler kit for FI applications, getting one?

[robispec]

oh the radiator mounts in the stock location A/C condensor bolts back up and all the stock mounts are used to mount the new Radiator too!

Can you post some higher resolution photos from a bit further away please? I can't really see what's going on in there....

And this was/is the OEM standard on many Honda engines for the last 25+ years. Random, useless and non-applicable fact....

im prolly just gonna put one together from an FC rx7 core. Ive always liked using them.

The location isn't bad, the placement is and here's why:

1: The air passing through the Oil Cooler first doesn't "ruin" it. The heat from the oil cooler radiator is only going to add a few degrees to the passing air (if that) and less as the air is flowing faster. And again as the air passes through the intercooler for the turbo/SC it's still only gaining a slight temperature increase (and less with increased flow) and thus why it's still effective (or "good air") when it reaches the coolant radiator. So this explains why the location isn't bad.

2: The placement is bad because of the gap. Air flow will always take the path of least resistance (like heat or electrons) and the problem here is that the rear face of the oil cooler radiator is not in contact with the front face of the intercooler and thus the air, after flowing through oil cooler radiator, creates a substantial amount of turbulence in the gap between the oil cooler and the intercooler. That turbulence creates a pocket of resistance and the air flow will try to flow elsewhere and if there is any easier path for it to flow (like around the intercooler) it will do so. So either that gap needs to be completely eliminated by butting the oil cooler right up against the intercooler (eliminated turbulence) or if that is not possible then the oil cooler needs to be relocated or all other possible areas needs to be sealed off so the airflow has no other option BUT to flow through your cooler/IC/Radiator.

PS: that the turbulent air that also reduces flow through the IC will also reduce flow through the coolant radiator but this is much less of an issue as radiators have radiator fans.

In my race car (N/A engine) I have an oil cooler in front of my radiator but I was not able to butt it right up against my radiator. I have a radiator fan on the side of the radiator that there is also the oil cooler and I leave it running all race long and I also took some measures to block off the area on the sides of my radiator so the air wouldn't flow "around" it and thus is forced through it.

I voted no, but that may change. My reasons; mild temperatures where I live plus the large amount of oil held by the engine should give it sufficient dwell time to cool off, the aluminum block should shed heat pretty quick, and I'm still hoping to go SC over turbo. Also, I don't intend to track the car. All in all I doubt I'll need an oil cooler. But I'm still open to the idea.

Does anyone know if the auto twins use an in radiator oil cooler for the tranny? If so, what size line is used? I doubt it would be big enough, if it's even there. But a quick look couldn't hurt.

I am planning on a new radiator as well as my oil cooler...PHX gets super hot and anything I can do to keep the temps within reason is on my list of things to do. I already have the vented hood, dunno how effective it really is, but I'll assume that any heat escaping through the vents is better than none at all. I am also going with the Chargespeed front bumper so i have actual usable side vents for the oil cooler to be mounted in it's own air path.



Dunno if I'm going with HKS for this cooler, but I want something similar.

But where will the brake ducting go!

Good question...lol!

Voted: From the looks of what's available out there I'll end up building my own.

Looks like cooling will be a problem for any FI car here in SoCal. Keep in mind there are two cooling opportunities to cool your engine; 1. Coolant. 2. Oil.

All you need are:
1. Sandwich Plate
2. Thermostat
3. AN Fittings & Lines (AN10 preferred but AN8 is probably ok)
4. Setrab (the best) heat exchanger
5. Brackets and misc accesories for install.

The problem in an FI car is placement. If it's a front-mount then you'll have 4 cooling elements stacked. Radiator, AC condenser, Intercooler, Oil Cooler, and in my case Trans Oil Cooler (which makes 5 elements). You really don't want it infront of the brakes ducts because the your brakes will suffer... This is the only time I wish our cars had a top mount intercooler.

There's no brake ducts on this car stock, hell there's not even anything even remotely diverting air towards the brakes. When I do go with some brake ducts I'm pretty sure I can route the flexible hose around the cooler.

Yes, obviously.. there are no brake ducts stock on this car. Though, too cool the brakes you'll either need to punch out the fender "brake duct" cover or run a hose from somewhere. If you have a hot heat exchanger there then............

If you make it work, let us know!

I'll finger something out

looks great
