That'* not a sticker. No surprise here, though:

Paul, probably 80-85 heatsoaked and after a sprint. My housing was always hotter than my nosedrive, but that'* typical wiht the faster spinning 62'*.

80-85 Wow. That is impressive. I have never seen less than 90 with my injection system.

I'll heatsoak it this morning and shoot it when i get to work.

After a rather 'spirited' commute this morning to work:

Top is LIM (post intercooler) air temp in bypass (not flowing fully through the core), bottom is trans temp:


If I were to close the bypass, the LIM air temp gauge would drop into the 80'*, as the air would be forced through the core as if it were in at least partial boost. Notice the AMP TEMP. Well, let'* call it a horsepower amplifier, shall we?

Body of the SC 30 seconds later:


Nosedrive temperature at the same time:


Nosedrive is normal temp or at least a little lower. SC housing temp is FAR lower than it normally is without the intercooler. My SC housing after running boost is always (or used to be) hotter than the nosedrive. Granted, my hood vents, high speed fan override, and coating help, but this was a significant change mostly due to the intercooler. The intercooler itself is thermally isolated from the LIM. It doesn't actually touch it anywhere, so this is a result of the temperature of the air in the LIM keeping the LIM temp down, in spite of the engine coolant running through it. Remember the S1 L67 LIM has a large water passage running right down the middle of each bank in addition to the cross flow from head to head.

My temp probe is less than a half inch from that long passage with coolant.

So from a cold engine, how long did you run it, assuming it was in town driving?

I know it'* only about a 5 minute drive to your work, and dropping Bo off takes what...10 minutes?

It takes mine about 30 minutes to fully warm up from dead cold.

Have you tried after a heat soak of turning it off once it'* warm for about 15 minutes and then starting it again?

After letting it sit and soak, then starting, LIM temps come back down after about one minute.

This morning, I idled at home to warm up for 10 minutes, left with Bo, idled at 7-11 for 5 minutes, drove to the dogsitter. Idled there for 5 minutes while he ate his snacks. Ran a half-mile sprint to highway 20, laid into the boost another mile down to Circle Blvd, and sprinted another half mile from there to HP (85mph). Hit the parky lot and took these temps.

Total time about 20-30 minutes of running.

That really IS impressive.

You got me lusting now......

That would be a good test but alot of plumbing refit to get the temp probes in there. Shooting the outside jacket would have too many varibles to be accurate.

I have seen variances on the front radiator when using it, but it'* already cooling off by the time I get the car stopped, run around, and shoot the face of the radiator.

I may be able to get some better ideas and see how well the hot water cools as it travels through the big radiator and back to the pump.
