racebronco2 said:It seems that my autometer gauge is not reading the same as the ecu. Up to 190 degrees they are both the same. Higher then that the autometer gauge reads a couple of degrees higher and at about 210 degrees the autometer reads 5 degrees higher then the ecu.
ShelbyGuy said:I'm starting to rethink my placement of the sensor in the block. I've gotten the exhaust hot enough to melt the plastic on the tank cover and to turn the tips blue. I'm thinking that the heat from the exhaust manifold is soaking the brass sending unit, making the gauge read higher than it would if it were, say, teed into the crossover tube with the factory sender.
racebronco2 said:It seems from datalogging that engine temps effect iat-2's more then outside temps. If engine temps were over 200* iat-2's were over 130*.If temps were under 200* iat-2 were under 130*. I did not include any temps if the rpms were under 3000 at the beginning( pre-grid) or at the end(cool down lap and driving to the pits). I am using the time line on the predator ;
sleepless said:I was starting to suspect the same thing; engine coolant temp affects IAT2 temp. This would explain why my IAT2s are so high at the track; I see coolant temps between 220-235 (but tomorrow is my first track day with the full Evans Cooling system, including external oil cooler So, we will be able to test the ECT/IAT2 temp theory?
Thanks for the great info!
sleepless said:Evans Cooling System definitely works! I was able to drive complete 30min sessions with no overheating problems today, for the first time! Yahoo!!!
But damn is it an expensive mod ... ouch!
Anway, my water temp peaked at 236 and stayed there. Before it would just shoot to 245 and limp mode within 15 minutes.
Now I'm going to try the 2.94" pulley (have the 3.1" now)...
I still see IAT2 in the 160's (not too surprising given it was running at 236 ECT). I suppose it's now time to look at some shrouding and possibly a deeper "spoiler" (the rubber strip below the radiator).
