Oil lines go under gas tank, up over bulkhead, down thru heater hose that went to defroster, down into long and thru the heater tube inside the passenger side long, out into area by the oil filter.
works very well, no extra holes to drill in tub, other than bottom of trunk.
No excess heat in passenger compartment from hot oil lines.
I even ran the oil lines thru the existing flex hose that was for the original heater, that way they don't rub on any metal and it keeps the heat in the lines.

as far as out the top or bottom....I tend to believe that the factory did some engineering for the GTs oil cooler and it vented out the bottom.

If it was good enough for the factory 914-6GT hotrods then it is good enough for me.

Heck they didn't even use front spoilers or rear spoilers.... works for me.

problem with that is, you ignore the circumstances at the time ...

the 914 wasn't rolled out until late '69. they we're trying to get a few of them race-ready for the '70 monte carlo.
they were under a lot of (time) pressure to get those cars ready.

i don't think that they had a lot of "engineering" going into any of those add-ons. as you mentioned yourself, they didn't even run spoilers!

they did what they had to do to make it work in a very short period of time, not what was the best possible solution from an engineering point of view.

heck, most of the early GT's didn't even have swaybars!!!

i think your argument is flawed. porsche had no time to put a lot of "engineering" effort into the factory GTs, yet a lot of people today take their modifications as "the gospel" ...

show me any modern race-car, including porsches, that dump their cooling air under the car, run no spoilers and no sway bars ...

proof and pudding and all that ...


you may want to copy that suspension setup below, it must be superior, after all, that's how the factory ran that GT ... (IMG:style_emoticons/default/poke.gif)

Andy,

Didnt your car have that suspension setup?
I seem to remember a pic of your red car in a very similar pose....

all of the water cooled 986s, 996s 997s and 987s seem to vent the hot air from the radiators under the car/wheel wells.?

yes, it did. just like any other stock 914. NO swaybars ...

then i started throwing money at the suspension ...

point here is, if porsche had put a lot of "engineering" effort into the GTs, you really think that car in the pic above would have looked the way it does?

are they race-cars? what does that have to do with how the GT's ran their oil-cooling?

you said they didn't have enough engineering time to do the 914 properly...
I think they had lots of time to engineer the water cooled cars...and yes the race cars vent the radiators in the same fashion....under car/wheel wells.

where did the factory 911 race cars vent their oil coolers? under the car? (IMG:style_emoticons/default/confused24.gif)

not going get into it with you Andy....it is not worth it.

I believe that my car works very well the way it is set up and I have had no cooling problems with the car in it's current configuration.

I might even run cantilevers on 8 inch rims (IMG:style_emoticons/default/biggrin.gif)

no one argues that it works. i never ever said it didn't work.

i have two points, however:

- dumping additional air under the car creates additional lift at higher speeds, no matter how you look at it, it can't be good ...

- just because the factory did this and that to the GT cars they raced doesn't mean it was the best possible solution. all it means is that it was good enough at the time to get the job done.
just ask your 914 god buddy what he thinks about the effectiveness of the factory GT stiffening kit.
wanna bet as to what answer you will get?

and don't get me started on the racing tires. you guys *completely* missed my point during that "discussion".
i'm over it. i know who to stay away from on the track ...

Yeah those GTs were really just cobbled together. Truely. BIG Fuching tires. NO areodynamics. Brutal Go-Karts pretty much.

It seems so logical to revise the (barely functional) "behr" airbox to exhaust right there in front of the windshield. The areodynamics would practically draw air out b/c that is a total low pressure area.

edit- Porsche wasn't attune to airflow until the 70s. Look at the early 917s even- they sit up a foot off the ground!

I thought BillP answered your concerns with his replies directly from Goodyear.

You won't have to worry about track stuff Andy...

I doubt you and I will ever be at the same event, and surely not in the same run group. (IMG:style_emoticons/default/smile.gif)

yes, bill did.
however, there were a lot of opinions voiced prior to bill actually calling goodyear that clearly showed a mindset of some that is borderline dangerous ...

i was not refering to bill, i was refering to some of the people that got into the argument prior to the point when we got the information from goodyear.

like i said, you never *got* my argument in the first place ... i can spell it out for you in one simple sentence, if you wish. it is still as valid as it was back then ...
