I wonder if the lower pulley is the issue. How much boost are you seeing on the first hot lap? Are you logging IAT2? I’d like to see peak straight speed on the first hot lap for your setup vs a car with full exhaust, porter blower, and a larger tb (but not pulley)..... and temps throughout the session with the no pulley setup.

If it’s a track only car, you could try removing the ac condenser. If you do, please report back with results. Same for distilled water.
Would like to keep the AC for right now. I will have to look at all the temps on the log and see what they are. Pulley may be the issue.

Been battling the jointly rising coolant temps 262+ and Oil Temps 300+ on the first lap with a 2650.

I have conversed with a ton of folks with stock blower, aftermarket blower, and ported stocker. Seems the thing that everyone that is able to do laps in their car has done is a seperate oil cooler setup.

I put a call into C&R today, as noted they don't make a radiator for the ZL1 or ZLE. During the call they stated that they found greater performance with seperation of the oil cooling from the engine cooling. Their solution is to replace the side cooler that performs secondary HX functions, make that an oil cooler, and put a larger primary HX into the car. Details to come out soon ISH.

For now the Improved Racing with a SetRab hanging off the front of the car from say the front crash beam is going to be the way to make it happen.

Maybe Improved Racing can help you with an oil cooler.
I saw this video the other day:

How much power? How much boost?

Which track? Ambient temps?

All of those mods' contribute to your issues. The car was validated under STOCK condition. You've altered the supercharger system, the cooling system, the ECM-tune, etc. with all of those mods'. By creating extra power, you've added more heat within the powertrain system and that heat bleeds into a lot of the rest of the car. Those heat exchangers, according to other Members (and I put it that way because they've found aftermarket heat exchangers, including radiators, to be detrimental - NOT brand specific either) don't do anything to help around a road course because they limit air flow and hold heat longer than the OEM set-up.

I wouldn't suggest that I know how to set a car up for anyone else, but it is my opinion that if you want OEM reliability and OEM optimization, you have to keep OEM parts and systems OEM. You've changed that with your mods'. It's your car, and I don't pretend to tell anyone else what they should do with their money, but there are Members still trying to figure this puzzle out, and your set-up is not effective in that regard, on a road course. If you want to beat on the car as Team Camaro demonstrates, then you have to run it the way they ENGINEERED it. That's the key - the car, as a system, is engineered. It is optimized. Unfortunately - your car is not, which is why you face the issues you do.

I only add that to be constructive. I'm not trying to sound like I'm attacking you in any way. This is the reality at this time though. There are others trying to find the solutions you are looking for, too, so I'd encourage you to keep checking in. Cooling system companies/manufacturers don't even have proper solutions yet, according to some Members. There's a magic the OEMs possess that we just don't yet have access to.



It is also my understanding that the ECM, in differing years, also bounce spark control influence from IAT2s to MATs. I thought I read that later ECMs use MATs for spark influence.

Just for clarification

I'm torn between the Improved w/ setrab and the C&R methods.

Unproven, just my thoughts at the moment: the C&R will probably do a better job of cooling the oil when the car is moving, may be an issue in traffic (probably won't be generating much heat though) and not sure how/if IAT will climb faster. Improved method worked well on my 5th gen 1LE, but the ZL1 has the intercooler added to the mix (concerned about stacking too many coolers and airflow through the stack)

I saw a thread once about locating an aux oil cooler 'under' the car, but don't recall where or how it would be mounted.?.

EDIT: I'm unmodified, but high ambient temps for most of the year are my issue. The first session out is the fastest and the car slows down the rest of the day and temps climb.......to the point I get concerned and dial it back

Did you go from stock power to 740whp, or where there intermediate steps (for track use, ignoring the street)?

My thinking is to use a 2650 to make “only” 625-650 whp. The 2650 is so much more efficient at that power level than the stock blower. I think if that’s the power goal and you can get there with stock headers- just blower, tb, tune- it might be manageable.

Stock to 740whp; yes.

If you just want 625. Do the JRE 125.

I’m running the car in TT1 and needed the power given the cars weight.

Then do the entire C&R setup.

Have you been able to test with the C&R setup?

There’s a forum member that has tested with the set up.

C&R have all the data a lot of logging and lots of information from labs from that customer at VIR. I’ve also talk to everybody from Mark Martin and R stands for race and several others. A secondary oil cooler resolves all the problems.

Being able to put it on the side and replace the secondary heat exchanger it is a huge bonus.

I had my headers done by header shield, they should ship to Jannetty Tuesday or Weds.

Heat is the enemy
