I have a new Setrab cooler and Mocal t-stat.

I'd like to install them next month.
Is there any reason why I shouldn't?

I'll be doing mainly a/x. May try a DE this year?

just check your rules to make sure you won't be bumped into another class.

production rules for roadracing won't allow for opening up the front of the car unless it takes the place of a light.

I'll pop out the grommets and direct the air from the fog light grilles.

Class isn't important to me.

Pull the front valence out and brace it for sort of an air dam and cut a hole in it for the cooler.....did that in the '70s and it didn't violate the rules (SCCA). More fabrication, but clean.

And be very careful of anything over 1" high in the road IPB Image

Glad to see you putting a cooler in...
perhaps a thread on it would be great, with pics and how you ran the lines parts used ...
.....for newbies like me...
thanks

Why not?

So, is there any harm in putting this cooler in the car?
The t-stat may cycle continually. Is that a problem?

got a temp-gauge with numbers on it?

if you don't get to 190 fairly quick, the engine is running too cold ...

i like this idea a lot. has it been done before? pics? is it as effective as a more central opening?

Do you need it? Unless your oil temps got over 220, I wouldn't worry about it. Unless of course you want to run 26 feet of oil line and make all those connections.

Sounds like fun to me! IPB Image

I have a cooler in Frank and Manfred....have NOT hooked them up as the engine has never gotten hot enuff to need them.......yet. They are smaller bore 2.0 and 2.2s....my 3.6 which has NO internal cooler needs two large size external coolers and it uses them....I can watch the oil temp climb, then stabilize and then drop 25-30 degrees after the second cooler comes on line.

As to "cycling"...the PORSCHE t-stat is not mechanical ...AFIK they have a waxy material that gets soft and opens a valve allowing oil to pass. Most cases it does not close unless the engine is shut off.

Z makes a good point that you really need to decide if all the work, expense and metalcutting is "worth it" for a small(ish) six.

I currently have a 2.2S-spec six in my car and its cooling system is designed to handle a more extreme engine in the ultimate extreme conditions, e.g., Willow Springs (high desert) in July/August for 20-30 minute balls-out sessions in 110°F ambient temps.

And I do use it in such conditions; however, in reality this means the cooler intake must be taped-off to get enough heat into the engine the majority of the time. However, I'd rather lean towards OVERkill vs. UNDERkill when it comes to oil cooling.

If your car doesn't get too hot too often, then you don't really need a $$$$ cooler setup.

It'll be interesting to see what kind of temps I'm getting once the guages are wired up.

I'll go and hammer it up on some hilltop back road... IPB Image

I can tell ya that when I've hammered my car on the local canyon roads, I don't think I've ever gotten it over 190-200° even in summertime.

Racetrack use is different as you are at WOT in the upper rev-range the entire time (if you're driving the car correctly). It is very, very hard to duplicate that on public roads.

What is the optimum running temp of the SIX?

If my t-stat opens at 180-190 what should I expect to see temp wise?

I go with what's stated by Bruce Anderson and Many Others more knowledgeable than me -- <190 is too cool; 200-220°F is "optimal" to burn off moisture and petro by-products, 220-230 is hot but not too hot, 230-240 is really getting up there but OK if it doesn't happen very often or for too long at a time, and >240+ is Too Damned Hot.
