Obviously, a 3.0-liter SC motor is gonna want an external oil cooler, but what about a 2.4E or S? Will an on-case cooler do the job, or is it iffy?
Also, who is using the right inner fender for the cooler spot on a /6? What size engine are you running and what temperature extremes have you seen?
Thanks!

the old rule-of-thumb was 175-ish HP.
but a 150-HP engine used exclusively for track events in SoCal/AZ/TX by two drivers is going to need one more than a 210-HP engine in daily-driver commuter service...
i've never seen anyone use the right-fender location in a 914.6 - 914's don't have the ventilation from the horn grille to the fenderwell that 911's do. and the folks that have done airflow studies tell me air doesn't come in the turnsignal tunnel like you'd hope it would, so that doesn't buy yo much either.
a 2,4S is kinda on the edge. i think you'd need it if you spent any amount of time on the track, probably not in street/AX service.
As I recall, the 2.4E used just the on-case cooler in the 911. The T certainly did. I think only the S used a separate cooler, and it was just the simple loop cooler.
The 2.2 in Frank runs at 225 when pushed.....180-200 otherwise....with no external cooler and NO engine sheet metal....prolly 140 ish hp.
Manfred runs a 2.0 "S" factory rated at 180 hp....have not had it on the track yet, but stays around 200 w/o a cooler in spirited street driving.
The Rocket, a 3.0 CIS 914 needed both internal and external cooling....on long trips it just kept climbing....at the the track it would climb to 220 and stay there with two coolers.
Red, has a 3.6 which has no internal cooler, has ALWAYS needed two external coolers....
Sorry, meant cooler in right REAR fender...
So is the consensus that street cars might get away with a 2.4 or so without an external cooler?
And does the tail-dragger get better wind/air cooling than the 914-6 did?
Thanks,
pete

rear fender is easy - it doesn't get any airflow to speak of either. i wouldn't waste the time, effort, or AN hose trying that approach unless air works different near your car than everybody else who's tried it ... |

I disagree. I had a 3.0 and mounted a 25 row Mocal cooler in the rear fender, and never saw more than 210, on a long trip in the summer. |
Just my opinion, of course, but don't fool around. Put a good cooler in the nose. Mr. Anderson goes along with the factory's
example of a cooler for anything over 170 hp (in a 911) or so, and claims that 6s run hotter in 914s than 911s. I'm not real sure about that last bit but will bow to his expertise..
No ex coolers in the 2.7Ls (165 hp)and look what happened to them. The 2.4L, S motor has 190 hp, so there ya go. The E had 165hp, which would make it marginal. My 140 hp T in the 914 didn't need one.

what were your temps before mounting the cooler ? |
