I got the Procharger Kit with a D1SC and Stage II Intercooler, at base boost, (that is 7 psi at sea level) thinking I could use this car as a DD and as a fast and dependable long trip touring car.

I am at 5,080 feet a.s.l. so the SC only makes 5.9 psi at redline, but even so, the I.A.T. soars high very rapidly. After some open road, high speed and high load runs, the car protects itself pulls timing and even the Check Engine Light turns on intermittently until it cools down under light load after 3 miles or so.

I checked a data log made with a DashLink device, it says Maximum Intake Air Temperature of 163 °F over 91°F Ambient Air Temperature and 5.8 psi boost.

I have checked the installation, everything seems to be right, all was made following the instructions.

I wonder if this normal and therefore you are not to use a Procharged Camaro as a normal car. How does everyone use them, are long high speed pulls normal? How much is the Max. temp gain you normally see post I.C.?

All help and recommendations are appreciated.

Joe,

1) I have already sent you a PM on this....
2) I wouldn't trust a "dash" link 100% without second verification.
3) Even on more boost, and that same intercooler and same outside temp I have yet to see anything close to that kinda temp.
4) How are you checking boost? cause that number seems VERY low.
5) Have you spoke to your tuner about your odd issues.


Have you checked some of the things I have asked?
Packing material in the intercooler?
Has the intercooler been painted?
Any "aero" modifications to the car?

I have personally road raced one of these cars in summer heat, on 9psi of boost.
NEVER seen it go into a "protect mode"....Have you spoken to your tuner about this?
There is no check engine light for IAT.... so you have something else going on there.


NOTE: Check engine light for IAT failure, but not high temps like you describe.

Did you install colder plugs like they highly recommend? Even though, I'm 700 ASL minus humidity. I was seeing 10* above ambient when I logged. That was before installing the colder plugs. I have yet to log again since I'm waiting on a gauge pod for my boost gauge. The boost seems right for altitude, but even with low oxygen in the air, the IC shouldn't let it get that hot.

Plugs have no bearing on IAT's.

I was thinking more for the check engine light. Ignition misses with the thin air are easier to achieve if he hasn't touched the plugs. This is assuming he didn't close up the gap on the stock plugs.

Or even knock if the plugs are keeping too much heat.

Hello Erik,
1. I received your PM, thank you, but you did not send me your email so you can see the datalog.
2. The AAT and AIT in the DashLink correspond to the readings on the computer, their behavior does move as expected, you can see that on the datalog.
3. Agree, that IAT is something unexpected to say the least.
4. Boost is read using a 3 Bar Map sensor, I also confirmed it on a Dino run using a mechanical boost gauge. There was no heat soak or high AITs on the dino run, btw. Also the Absolute pressure in the BAP reading is correct while the engine is not running.
5. Yes I have, he considers the car is protecting itself due to the high IATs, it is doing as it is supposed to, tune wise.

I also checked the installation and it is all OK (I have not checked inside the IC yet, that is very complex to do as you know, and there is no reason to have anything in there, so I want to discard other possibilities prior to). No paint on the IC and no aero mods to the car, the kit is installed as per the instructions.

As I stated, all help and recommendations are welcome. But please let me know: are long high speed pulls normal using the Procharger Kit?

Yes, NGK 6510 gapped to 0.035" as the Procharger Manual recommends. There are no missfire codes, or any codes whatsoever.

You've got something not right. Procharger makes a kit that's fine for Dd, and it normally has lower iats than a top mounted blower. Good luck figuring it out.

I have done pulls from dead stop, to the top of 5th gearing.
And have not seen IAT's as high as you are describing.

Nor have I, during road course adventures lasting up to 20 min.
Constant WOT and of WOT conditions.

Doing a long highway pull on these LT-1 with stock ring gaps.
Usually ends in a broken motor really quickly anyways.
So not something I go test often.

Thanks for the answer Erik.
How long do you consider too long for base boost?

I will have the Intercooler dismounted and checked tomorrow, I will report on findings.

I thought .042 was needed with these?

I depends on the car's specific setup, for the base Procharger Kit, they do recommend 0.035"

I got ya, I like the tighter gap idea anyway lol

Erik,

As you requested, I had the car dismantled to search for those things. As I tought, there was nothing to be found, pictures below.

I would very much appreciate if you could answer my previous questions and also inform on how does Procharger take care of their customers in the event a Kit with Stage II Intercooler and base boost does not cool properly.
