Posted by: Aaron Cox Sep 2 2005, 08:36 PM

Today i decided to embark on my journey to prep my car for -10 braided line, and a 16x3" setrab Oil Cooler.

STEP 1
cut square hole in passenger foot well area for lines.

STEP 2
Decide whether to run braided lines up the rocker area, or throight the heater tubes.... idea.gif idea.gif idea.gif beer3.gif idea.gif rocking nana.gif

STEP 3
Decide that running lines down the rocker is easier to access..... cut access holes to go from rocker area to inside footwell like GT cars

Step 4
Cut outside access hole

Step 5
Cut front trunk access holes for lines to run to cooler....

Step 6
Marvel at your ugly openings, and take an artsy fartsy hole to hole shot

Step 7
Drill out 6 spotwelds holding down the spare tire mount, prepare to move it vertically to the firewall to secure a spacesacer like this (STEVE's car)

Did i mention that AN fittings are a royal mot**r F****ng pain in the @$$????

hmmm are you lubing up the hose and fitting?

-10 should be a piece of cake to assemble.. its the -16 and -20 lines that are a pain in the nads

1. wrap hose with tape.
2. cut in the middle of tape.
3. deburr the end with diag. cutters.
4. apply vigorous amounts of wd/40 or 30 wt oil
5. swear swear curse curse and get red fitting over braided end.
6. push blue tapered fitting into rubber hose.
7. tighten.

i did 4 ends today. still picking braids out of my hand....

Way to go aaron! So you decided to go down the rockers?

It was kind of a pain to go through the heater tube, but it only took me a couple hours to cut all the holes and run the lines. Seems worth it now. No regrets.

Mine is about 90% done. The hard part is over. Too lazy to take pics and too excited to drive it again. In the process of buttoning up the interior and then... driving.gif driving.gif driving.gif

I can tell you're askeered of me with that new motor... already thinking of a 2300++ lol2.gif

Before you run the hoses, try and get some sheetmetal edging so the edges will not cut that braided hose you drove so far to get. It is available at places like Marshall's in San Diego and will not only prptect the hose but make it look really professional. If you can't find that use some small black vacuum hose and slit it and put over the edges, I've done that with success too. Looking good so far!

Posted by: Brando Sep 2 2005, 10:50 PM

to make it real pretty, we can cut up some aluminum and put doughnut rubber washers/seals inside just the right diameter for the hoses that you can screw down over the large sharp square holes.

Posted by: Aaron Cox Sep 2 2005, 11:05 PM

I have dozens of -6, -8, and -10 fittings on my car.

The best $$ I have spent was on a giant pair (36") of hose shears, they cut thru even -16 braided hose like butter making a clean and ready to install hose end. You can get a set from mcmaster for around $100 or less.

agree.gif werd up

I was just looking through summits new catalog whilst in the library, and noticed that they are selling the shears for $39.95

Also the brand of hose end seems to make a difference, XRP, Aeroquip, and Earls are slightly different

iirc earls are the more difficult to use

Posted by: SLITS Sep 3 2005, 08:27 AM

A Dremel / DoMore with a cutoff wheel will make a nice clean cut.

I would soft vise the fitting and push the hose on.

Also, after pushing the fitting on, I would mark a line on the tape at the end of the fitting. When I screwed the second part of the fitting on, watching the mark would tell you if the fitting was pulling out of the hose.

Oil cycles all the time, you dont purge it unless you want to.

and... guessing 4 more quarts....

Posted by: rhodyguy Sep 3 2005, 10:26 AM

wouldn't that be the fan thermostat? i was refering to the non-existant one for the cooling flaps. over half a box of oil when it's time for a change, nice. i hope you're going with the real exspensive stuff. bootyshake.gif

no silly fan thermostat. but your extra cold oil point is moot. 5% of the oil is always circualting through the cooler. at 180 deg, 100 percent is going to the cooler....

5. swear swear curse curse and get red fitting over braided end.

I use a Gould pipe vise (pictured) with cutting guide for cutting hose; a sharp 32-TPI hack saw blade goes through in a few strokes. use a couple of turns of racer's tape in the area of the cut; mark the tape. the pipe vise is small enough to go into the track box.

it's usually easier to put the red fitting over the hose before you cut it.

SLITS is definitely right; grip the fitting in "soft" (aluminum or brass) vise jaws, push on the hose. the rest of his tips are spot-on too.

there's an illustrated guide on the Earl's site.

If I want to drain my lines I just pull both ends off the sandwitch adapter and fire up the air compressor. Put one line in a catch can, stick the blower in the other line...presto drained lines!!!

Otherwise looks good...

the great thing about external coolers is the number of new places to spring leaks... That extra 3-4 quarts will defiantly come in handy in your cone-bashing exercises. Finish up and suck a few after the test drive. clap.gif clap.gif clap.gif (oh god! did I just give AAron the clap?!!!)

works fine with no ducting and no exit as of yet...

ill have it ducted and shoruded as of summer...

gonna go ALuminum i think

Posted by: agrump Jun 5 2006, 03:36 PM

Excellent! Thank you. I was just measuring on my car and I think I am going to have to go with two 8x4 coolers to get around the spare and the AC condensor. Should be about the same surface area as what you have. I'll be able to duct it out the wheel wells if needed.

Posted by: jhadler Jun 5 2006, 03:43 PM

Was currious about the overall height of the cooler and fittings. I have am aftermarket spoiler with a nice opening that I'd like to fit that cooler into. I'm trying to keep the overall height of the cooler with fittings to 6". Do you think that with 90 degree fittings, that it might make it under 6"?

Thanks,

-Josh2

Posted by: Aaron Cox Jun 5 2006, 03:47 PM

with 90's? hmmm i would think it would be a tad too tall. cooler is 4" and the fittings may be taller than 2"......

maybe with the 135 degree fittings.....

Posted by: Brad Roberts Jun 5 2006, 05:46 PM

That cooler is too damn small to be effective on the track Josh. Step up and get a Fluidyne that is the same heigth/length but double the width.

I installed a 13 row Earls in a 914 (in 6 hours the other night) Worked perfect at Buttonwillow with the air temps in the 98deg. range. Kept everything in check. I needed a cooler quickly for this event, so I went against my own "Fluidyne" preaching.

Aaron,

I like the concept of runnin through the rockers, but cutting into the frame rail TWICE is not something I think I would want to do. I ran Birgit's through the heater tube and had it exit out of the factory hole in the frame rail just behind your exit point.

and brad... it only went thru the long once. not TWICE. the front went in from the fender opening, and that put it into the middle of the long.... and thus only came thru the INNER long.....

Yeah, I'd go for the fluidyne if I really could. But I'm forced to face a compromise in this. The rules I'm running under do not permit the cutting of sheet metal, nor do they permit ducting air _to_ or _from_ the oil cooler. However, they _do_ allow an oil cooler to be placed _into_ the opening of an air dam, which is unrestricted (the air dam that is). So... the best off-the-shelf option I've found so far is to use the RSR style spoiler that GT racing makes. Only catch is, I have _yet_ to find a relatively thin (earls, setrab, mocal) oil cooler that actually _fits_ in that opening. The only thing I've found that would fit without customizing the spoiler is a cheapo AN6 sized transmission tube-n-fin oil cooler. And that would be almost worse than nothing. Anything thicker than those plate style oil coolers would have no space behind 'em for air flow, rendering that awesome (and expensive) fluidyne useless... So.. back to the compromise...

Any suggestions? I'm open to new ideas. smile.gif

-Josh2

Posted by: Aaron Cox Jun 5 2006, 11:04 PM

sounds like a seperate thread is in order chairfall.gif

here is my idea, modify the GT racing rsr valence so the cooler opening is like 3" further forward then it currently is. thus you have more room in the back, and it might look cool

its just fiberglass!

Pick up the finned aluminum tube coolers used in NASCAR. For Auto-x they would work fine.

Other wise mount two coolers behind the bumpers in the opening for the factory foglights and use the delete grills to feed air. Better than nothing.

1) Where would I find one of those coolers? The only tube-n-fin coolers that I've found that fit the existing space are AN-6...

2) If I mount behind behind the grilles, where would the air go? I doubt that much, if any, air would actually flow through there.

Yeah, that's true. 3" further forward, that sucker would be hanging quite a bit out there. It already has quite a snout as it is.

The reason I want to stay with an off-the-shelf spoiler is that I know that at some point the spoiler will be broken. It's inevitable. So, I wanted to stay away from having to lay custom fiberglass each time, just order a new spoiler. I guess I could make my own mold and fabricate my own spoiler every time, but what a pain.

I guess I'm searching for a non-custom, easilly applied solution. I know, a pipe dream. But one can dream, can't one?

I'm impressed JP got two -12's through there!!! 10's go through easy!

Aaron,

Ask your buddy Matt about some of the hacked shit the "factory" does to get a car to the track. I swear that half the stuff we see for the 914 that the "factory" did was all "patch work" they put ZERO engineering behind some of this. They are in the business to sell race cars. The tubs didnt have to last smile.gif

I like your setup. I personally beleive/know the cooler is too small for anything but sitting in traffic or a short 40sec AutoX.

When I run the bigger coolers, I drop them down farther into the tub so they stay under the GT shroud.

Josh is in a tough spot. He will have to runs something very creative. I find it hard to beleive a race org wont allow better cooling. It has not effect on performance..ha ha..

Yup. On both counts.

Right now, I'm keeping the oil cooler hardware on the shelf 'till I get the car running. After that, I'll look into different options again. It may wind up coming down to cutting and re-glassing the spoiler to accomdate a 6-1/2" tall oil cooler, we'll see...

It's SCCA autox. Street Prepared category. The rules do not allow cuttnig of sheet metal beacuse of weight reduction. I dunno, I'm almost to the point of saying #$&* it, and doing it right, but it would be protest fodder the moment I go to a National event. No, it's not a performance advantage, if anything, it's a dissadvantage (weight), but the rules are the rules...
