and heatsoaked ICers.

my AITs are crazy high on most dyno pulls. I always let the IC cool off on my last run on the dyno and get crazy elevated results.

I give two shits about my underhood temps. My intake sources fairly ambient air, and my IC sheds 80-90% of all the heat the turbo adds. My cooling system keeps my coolant betwen 180-190°F in almost all situations, so I have nothing to gain from a reduction of 20 degrees at my fuse box and wiper blade motor.

Then you've clearly never experienced fusebox heatsoak. Terrible thing that is.

I agree with you there. My dyno example was strictly trying to provide proof of what I'm sure we already know; lower temperatures = more power.

Which is why you should datalog on the roll. It's more real world than a dyno with a fan.

That's weird, I thought I just pointed that out.

I agree. I think it is especially important on intercooled cars since they don't use a fixed speed dyno fan on the road or track. Same thing with cold air intakes. Or driving with your hood up like many dyno.

That just struck me as very funny. Wife doesn't understand.

Your wiring harness says otherwise.

Braineack 08-10-2011 07:33 AM

my wiring harness is a boss.

Reverant 08-10-2011 07:38 AM

Impossible.

Cconducting electricity.... Like a boss.

I dunno, it's put me in my place. I'm bowing before it. I keep prodding it with my DMM and it's like "TROLLED BITCH."

it doesnt matter it raises your oil temps so i would rather have lower oil temps. reguardless it looks stupid. give up trying to justify it.

this topis is so worn out and old.

The only oil cooler on a miata (unless you added one) is through the water. If the car has enough cooling that the thermostat can continue to maintain a constant water temperature with the decrease in airflow over the radiator then there should be no affect at all on oil temperatures. Is there something I'm overlooking?
