Hi All,

I have a '69 Camaro with an LSx with F1R ProCharger setup. When the Intercooler doesn't get heat soaked, it makes over 1200 HP at the ground. The problem I'm having is the Intercooler we ordered from ProCharger was rated for 1000 HP cooling. I expected to only make 1000 HP at the crank but my engine builder overshot things a bit.

The front end of the car is stock, as in it still has the hood latch. The core support is also stock. I'm hoping that someone makes a 1500 HP capable cooling capacity intercooler to fit in the front of the car.

I know Ron Davis Radiator Company makes a very nice intercooler, but it's rated at 1000 HP cooling capacity. He said he could switch it from twin inlet to single for me, though.

Here are the specs for the intercooler I have in the car, now:

27" Wide, 15" Tall, 3" Deep with a 6" Core

Any help will be appreciated. Thank you.

I'm running the treadstone tr1245 1000hp intercooler on my 69 camaro. It is the absolute biggest one you can fit in front of the radiator support. With stock hood latch and fog lights. I'm making well over 1000whp with it and no heat soak issues.

Is your bypass valve before the intercooler ?

HP is a dumb way of rating intercoolers even if it is commonplace. Requirements for a 2.0 making 1000hp with say 40psi boost and lots of hot air would be very different than a 7.0 engine with almost no boost and cold air making 1000hp. One would need lots of cooling ability, the other almost none.

How can it have a 6" core...and be 3" deep ? Post a picture, your dimensions dont make sense.

And exactly what do you mean by it is getting heat soaked ? Have you no airflow to cool it ? Are your charge temps rising or do you mean the actual core itself is getting hot ? how hot ?

Under what conditions are any temperatures rising etc ?

And really..any custom fab place could make you a unit whatever size/shape you want or have room for.

Procharger use to use garret cores but I think they changed suppliers. Anyway I have a 67 and decided to go with hood pins. It really opens up real estate. I went with a bell core 20"x12x3.5".

HP ratings on intercoolers don't mean much. If you're actually thinking you can't make 1500 HP because your intercooler is only rated for 1000, then forget you ever seen the rating and carry on lol.

I wish I could find some real information on flow capacity of intercoolers.

I don't have heat soak issues, but I'm wondering if my intercooler is a flow restriction at my power levels. It's a 4" wide cxracing ebay intercooler. I guess I could fab up a second map sensor pre-intercooler to see how much pressure is at the front of the intercooler to see if it's worth me swapping to an intermediate intercooler like a Treadstone.

stevieturbo

Easy test, measure pressure across it.

Yes, it's easy in concept... I just need to figure out which sensors to use, and how to data log it.

I have a feeling that my intercooler is hurting me up top in the rpm band, but how much, I don't know.

stevieturbo

Could be as simple as two bits of pipe and two mechanical gauges and take a video of them.

Or you could log them individually from separate sensors.

Or use a pressure differential gauge or sensor.

Sensor would need powered....that would easily be picked up from the 0v/5v from any sensor around the engine. If you've nowhere to log it on your ecu, just hook it up to a voltmeter and watch or video it.


If you do use two separate cheap gauges, just test them both to ensure they do actually read the same.

Obviously if you have an ecu, or some of the Innovate stuff etc you could log the sensor properly

I do have HPTuners, and the ability to log an additional 4 sensors. So maybe that's what I'll do.

stevieturbo

Then you could do that with either the differential sensor or a couple of map sensors.

6669 camaro do you have any pics of your intercooler setup in your 69 camaro that's what I'm trying to figure out in my car right now. Thanks

Here's a link to my original build thread. They are some pics of it in there.

Op,
which "kit" did you use? Did you go with pro-charger transplant kit?

I ran the CX Racing 31 x 12 x 4 intercooler on my Camaro years ago before we switched it over to air to water. It ran a 9.12 with the CX Racing intercooler, the car would of gone faster if it wasn't driving through the converter. I don't remember what the inlet air temps were but it wasn't getting hot.

I did have one customer who had one in a GTO that had a major restriction in the intercooler. Something in it wasn't built right and when he swapped it out for another intercooler the engine produced a lot more boost, so it's indeed worth testing it. Bob

I've made 931whp and went 5.50s on this intercooler. But it is quite the restriction at these power levels/airflow.

You have quite a few choices for intercoolers. Treadstone is a good choice, as is Shearer Fab A2A. But that one is expensive.

Hi All,

I had posted a bunch of pictures with my original post, but they seem to have somehow not been included. I'll try a different way to show pictures of the intercooler I have in the car, now. Also, the IATs are climbing from 120F-140F to 178-199F during a quarter mile pass. That's pretty hot!

Also, thank you all for your replies. I've been very busy with work and family so haven't had a chance to log back into the site until now. I very much appreciate you taking the time to answer.

I will post those pictures of my setup as soon as I can figure out how!
