TravisLambert isn't the only one who has experienced heat soak at the drags. People on here thought it was funny I was using portable fans to help cool the intake and engine between rounds at the strip. As long as there is no flow through the intercoolers, there will be heat soak. I'm pretty sure that making a few passes in a row at the drag strip will yield less of a loss in et than making one pass, and then sitting for a few minutes to let it cool off.

I think turning the car off, setting up a big fan blowing onto the center and driver's side heat exchangers, and forcing the intercooler pump on would be a lot better though. |

The car really needs a cool down mode like the dodge demon where it will run the fans and coolant pump with the engine off. |

Well I drive it to the track anyway, so I'm not sure the temps would exceed whatever they were at during normal driving if you're just idling.

It will absolutely heat up more idling than driving because the airflow from the fans is not as good as the airflow from the normal driving. That's why it's so common for parade vehicles to overheat.

I've often felt it takes several thousand miles for an engine to fully break in and loosen up. While it might be trivial, I wonder how engine temps are effected as the frictional losses decrease over time from a new low mileage engine?

Ahhh good point.

I'm confident that our ZL1's do MUCH better than the late-model Corvettes in dissipating heat, but believe there's merit in the suggestion that there could be added benefit in larger coolers that are thermostat-controlled and allowed to run regardless of whether the engine is running.
I made 15 passes with my ZL1 at the Arkansas Mile earlier this month and saw the impact of heat build-up firsthand. With afternoon temps around 91 degrees and a wait of 15 minutes to an hour between runs, I saw a definite drop-off in performance. Putting a 20-pound bag of ice on top of the SC between runs got me back about 2mph at the mile mark. Talked with several drivers who had installed intercooler chiller systems that circulate iced water during their runs and they claimed to get 4-6mph at the mile. |

You should be using a handheld IR Thermometer to measure AND LOG some of the follow temps; 1) Engine Block 2) Radiator 3) Transmission/Clutch Assy 4) Coolant Lines 5) External Coolers 6) Rear Axles 7) Brake Assy/Rotors 8) TIRES(graduated) 9) Drive Belts 10) Forced Induction, (graduated) 11) Exhaust Manifolds(independent) 12) Driver 13) Wheels (If I've forgot something please feel free to edit as I haven't had my coffee yet) Keeping a log of both the location, time and ambient temps can tell you alot about how each component is performing or not performing. An EGT Temp can be handy when tuning or diagnosing an engine. Here's a good handheld IR FLIR TG54 Spot Infrared Thermometer DON'T FORGET TO LOG YOUR DATA |
