Chad's 68 Camaro V3.0 build. LS3 & TCI goodies

If you bring up the RPMS and the car cools off --- I'd be looking at the voltage your electric fan is seeing at idle. I assume you're running a relay -- but perhaps not heavy enough gauge on the power side.

I bought a 37 Ford once that had an overheating problem -- well DOH! The fan was seeing 10 Volts... That was certainly easy to fix.

I hadn't thought of that Greg. I'm using the Mast relay built into their harness. I will double check it.

This could be part of the story but isn't the whole story as I can duplicate this behavior on the freeway with the fan off. I turned the fan off with my laptop and saw stable temps ~210* in 6th gear 70mph but when I ran 4th gear at 70mph the temps dropped to below 200*. So I think there is something else going on too.

Regarding lean vs rich. The car is pretty stinky right now and if I don't clean it builds up a layer of soot on the tail panel so I think it's to rich. Oh and it gets horrible MPG. Around 10mpg around town. A best of 15 on 100% freeway drive.

Sounds like your water pump pulley may be to under driven. Meaning, to big.

To fat can cause high exhaust gas temps as well.

I'd dial in the tune before you worry to much more about temperatures.

Thanks Todd. I will get a dyno tune scheduled ASAP.

In the mean time I've been researching oil pan adapters and most of them are not great for my Champ / Autocraft pan since it kicks out to the side. I stumbled on this genius solution on LS1tech. I need to find someone who can make this!

Nice looking adapter. I am not sure but I think Brett at Fab53 may be able to build it for you and he is in the LB area. Another option, if its not hard to take the pan off, would be to tig the fittings onto the pan that way you can set the angles up to work with your set up.

But honestly I would do the tune work first before going any further.

Chad,
Can you post a link to that thread on tech?

How about the Mocal thermostat that Improved Racing also sells? If there is space downward it might work for you.
