cutting holes is fun and you know it:

BTW, what size AN hose is good for the cooler system? 8, 10? Used to run 12 on the Mustang that saw some open track duty.

no way I'm doing that shit to my car :nono:
I think running some tubes from the OE spoiler vent holes to the cooler mounted at the rack will work. Though it my seriously increase the need for a hole in the hood to vent some of the pressure.

-10 is the usual recommendation for "our" application

IDK i was going to put one on the shelf of the firewall a nice thin design should work just fine and get alot of flow. :dunno:

I think all depends on how much you're looking to lower your temps- and that'll dictate size and exposure. I need to drop them a lot if I'm going to track this car in the summer... one day.

Hey Rob, just ran across this from my holsets manual and thought i'd post it here for you.

I guess that proves that your temps are quite a bit too high.

fred.

or maybe it shows why holsets are such a bargain ;)
yes- it's still a project.

apologies for my inability to take your tease/joke :-p

garrett are a pain in the arse for finding info "please refer to your authorised distributor" etc etc

but i found this for one of their aviation products :

rgl.faa.gov/Regulatory_and_Guidance_Library/rgMakeModel.nsf/0/c5724721927d08cd862568f6004c3de6/$FILE/E3WE.pdf

this page lists nominal operating temps at 90C :

also, all the oil temp guages have max around 300 - 320F

i know its still a project, i just remember you discussing what was and wasnt too high, so thought i'd post up what a reputable open company that i respect has to say on the matter.

the "normal" companies (cough-garrett-cough) website is so packed with marketing garbage that its impossible to find anything useful if indeed it is available.

I don't know what my temps are post cooler, but I can only hope they're cooler than the oil in pan post combustion at ~275f or so. My oil feed leaves the block immediately after returning from the cooler, which IMO is ideal. Another reason those sandwich plates or the T at the pressure gauge are good idea.

I don't have a condenser to worry about anymore, but here is where I put the cooler in my car.
Gotta love cell phone pics.

That's nice. I've got an large IC, condenser and extra large rad stacked in there. I had the little oil cooler floating out front (after the big IC install) and there was insufficient exposure AND it's just too small (smaller than yours for sure- smallest trucool).

Sometimes if it weren't cell phone pics, we'd have no pics at all. :D

a little progress
 

Got the new Mocal plate installed. The main diff between Mocal and the Hayden:

• Mocal 1/2" ports
• Hayden 3/8" ports
• Mocal true coil spring tstat
• Hayden flat coiled steel that covers bypass hole when hot
• Mocal is about 1/2 the thickness of the Hayden

As mentioned before, the Mocal does well with some porting on the internals. The larger 1/2" ports leave some very hard edges and extra metal hanging out at the transition. Dremel with small carbide tip will clean it up in minutes.

The more shallow Mocal caused the fittings to interfere with some bosses on the block so it was far more difficult to install the lines. All adjusting had to be done off the block, then reinstalled to test fit. Bending -10 braided lines is a bitch in such a tight spot- inevitable the lines don't watch to thread straight, so patience is imperative.

I just left the small cooler installed since the larger cooler is going to require custom lines and maybe fittings. I'll just keep an eye on the ebay nascar surplus for deals. Anyway, this will give a direct comparison between the two plates for performance.

I played around with positioning the new big cooler in front of the steering rack and getting air from the spoiler ducts is going to require some serious plastic fabricating. The ducts are definitely design to go right to the brakes- which means I'll probably end up hacking the back side of the spoiler ducts up to get them over to the cooler.

Mine's around the size of the larger photo above. I don't have a condenser anymore to get in the way. I don't have a thermostat, but the OEM water/oil cooler, so the oil temps are still being adjusted by the coolant temps. The lines are -8. The adapter on the block and remote adapter were touched up with a die grinder and cartridge rolls to enhance flow. The 90º fittings were also kept to a minimum.

You don't need a tstat in the everglades. :D
It was 22f the last time I drove my car, that's the only reason I have it. I really want to keep the a/c and have gone to great lengths towards that effort up to this point. There's room for everything up to this point, so that should be the last item after the go-fast stuff is sorted out.

IMO you won't need to cut any holes in the bumper. There is so much turbulence and air moving around there because of the tire so most likely all you'll need is a fan to force circulate air through the cooler and the tire will take care of the rest ...

I hope so. Plan was to install it first and see what the temps do. If they're still too high, then run ducts.

I've done some driving and the oil temps are nearly identical as before with the Hayden sandwich plate.

So the next step is installing the big mercedes cooler. And I've decided at this point to install it next to the radiator in place of the cold side IC pipe, and then run the cold side IC pipe around the rad and up to the TB. Just makes sense to do it this way since that really is the optimum spot on my car- direct air flow and better access to add a fan.

son of bitch
 

Day off and I'd planned to get the coldside IC pipe rerouted around the rad and get the oil cooler mounted. Looked to be a perfect fit until I slid it up and it came to a stop on the rad filler neck. :vash: Few pics to show the old IC pipe routing, oil cooler "almost" where it will go and the interference. I guess at this point I've got to cut my filler neck off and move it... somewhere. I might do a remote like splitime/dave. :dunno:

That's gonne be pretty nice when it's done. You could keep the filler neck on that side. Cut the neck and that hump off and move the whole thing back towards the motor. So it's offset closer to the throttlebody. That would give the cooler room and keep things simple. Just more aluminum welding.

:eek: I'm gonna need about 6 hours of practice before I put the mig to my rad... or I'll just wuss out and pay. But that puts the car outta commission. If I mig it right, it's done and I can reassemble.

I think it will be a good solution when it's done. Essentially a "twin" cooler with far more capacity and double pass cross flow rad for ~$300. When I'm done with this shit, I better have some oil temps in check. :cool:
