Need some recommendations: Going custom twin turbo setup in a couple weeks. Twin PTE6766s T4 turbine housings, .96 A/R

Car is a 5th gen camaro with an HKE built LSX 427 stuffed with all the goodies and Pat G blower cam, Mast 6 bolt black label 305 heads. Currently running a D1SC (over tasked) from my OE motor.

Anyway, will be between 1000 and 1100 rwhp. Entire driveline and suspension is built. Set the car up for the 2.5 mile road course to run a few times a year at track days, nothing competitive. Its mainly just a very well setup street car.

Was looking at the Procharger 1300HP race IC with dimensions of 27" x 4.5" x 12.5" with 3.5" inlet and outlet.

Costly but i want the best to keep the IATs in check and cant really block my entire radiator since i plan on the road course so 12.5" tall would be perfect.

Read a thread over on Camaro5.com that sort of bashed PC intercoolers. My research however has indicated they are pretty damn good.

So, i ask here, what is the best FMIC to go with for my setup?

Thanks

Heard some good things about Bell ICs????

BTW, price not an issue but quality is.

Had good luck w my treadstone. Think it may be close to maxed though.

Might be cheaper to get something similar made with Garrett cores ?

bought a garrett core through thompson motorsports. Way cheaper to have someone put tanks on a intertcooler than to have garrett do it!

You mention you plan on road coursing the car. Are others running a similar setup? A big concern is cooling for road course cars is cooling full stop. So sticking the biggest intercooler in there might be great for keeping the IATs low, but will that impact the engines water temps?

If you are confident that you have the above covered then I say stick the biggest and best core in there you can fit. Don't forget the end tanks either. Try not to have big box end tanks as these take up space that the core could be using and dont flow as well as people think. Have a look at race car end tanks to see what really works.

Are you planning on a vertical or horizontal flow path?

I've had good luck with Bell Intercoolers in the past. The cores aren't cheap but at 1k rwhp what is?

ayousef

not trying to steer off-topic but how are you going to roadcourse a 1100rwhp car? unless you plan on turning it down considerably, also considering the car is heavy and the TT kit and an iron block don't help much? I try to do crazy **** with my ZL1 in corners and turns and nope, not a good idea.

Not actually sure what a US road course would entail ?

I assume a lot of them are still fairly straight with few bends in the US ? So overall speeds are fairly fast ?

Can't go wrong with a treadstone core and not too hard on the wallet either

You want the best?

This boy set the current 88mm turbo and ET record. Ron can also do custom end tanks for you.

Whilst I'm sure the above is great, you cannot compare a long distance road course type race with a 1/4 mile that lasts 7-8 seconds

The amount of heat developed and needs to be removed are totally different, as are cooling requirements for the engine.
I wouldnt be wanting to place a 6" thick core ( didnt even know Garret made one that thick, unless they doubled up ? ) in front of a radiator of a car that needs to cover distance.

Pretty much anyone can fabricate a huge intercooler using a quality core.....it alone certainly wont be the reason a car sets records.

The only one thing for sure, is have one custom made to make the most efficient use of space available.
Buying off the shelf, unless also intended specifically for your vehicle, will always be more compromised than something made to suit.

/\/\/\/\ and the reason most race cars with have separate airflow paths for the intercooler and engine cooling. Makes it much easier to control the flow and get sufficient air going through the core rather than the core acting as a huge heat sink.

Gonna run a low boost setting for road course, maybe 10 or less. I also realize the right foot has alot to do with control-ability.

We did a corner balance on my car and am at 4112lbs and within 6lbs on each corner. Running a full Pedders roadcourse suspension with humongous Pedders ZL1 sways and adjustable camber plates. Running -3 deg camber for road course.

Also running 305/30 19s on all 4 corners with big 6 piston brembos and Cobalt Fricton XR1/XR3 pads.

Car is crazy sticky in turns such that i am more worried about oil starvation than anything else.

Heres a write-up by JusticePete, President of PeddersUSA on my last trip down to visit him.

And remember, this is not competitive road course, just the occasional track day to have fun.

Turns out Procharger runs Garret cores. The one i am thinking of measures 27" x 12.5" x 4.5" thick with 3.5" inlet and outlet. Pretty much the same height as what i am running now but 1.5 in thicker and flows up to 1300 hp.

I only plan on a few track days a year running 20min sessions and can back off when temps start to climb. Im more worried about oil temps than inlet since i run meth also.

stevieturbo

Fit an oil cooler then. For hard track use, and even more so in a warm climate, it would almost be essential.

It would also be sound advice to run a colder stat too, as a the actual engine itself will also help to keep the oil cool.

I know you are going to be making a good bit of power but I wonder if the super chiller could work on your car.

Way ahead of you on oil cooler. I installed an Earls wide 16row cooler with no stat and -12 feed lines. In the summer here in 105 deg heat and stop and go cruising temps sit at 225 and when romping on it get up to 240-260. In winter, i dont shut it down till the temps hit 195. so basically i dont short trip my car.

have yet to road course it though, hoping to keep the oil temps below 270 for at least 5 laps on the 2.5 mile course then back off if the temps climb. And i am running a full sweep electrical oil press and temp gauge, not the factory crap.

Thanks Stevie!

Maybe a 6" core/long across the bottom opening of the front grill? 10" high or so?

The intake temp builds pretty good on tight courses, don't know about the longer one's.

I've got a few supercharges guys that run small cores and 5 gallon meth tank systems on road courses.Usses some good amount of meth but the engine temps actually went down 10-15 degree's on average from freezing the intake/cylinder heads.

BullF-16

The one im looking at from PC is a 4.5" core 12.5" tall and 27" wide. Has the tanks on the top and bottom or core. Rated at 1300hp so with me at a measly 1000 or so RWHP i should be good. It leave a good bit of airflow to the radiator. I am running an ALKY meth system with 4 gallon cell in the trunk.

Certainly the Procharger piece does look great. But again, I'd say have one built specifically for your vehicle ( assuming the Procharger is not )

I cant see it costing any extra, and it will just fit better really. I wouldnt go anything thicker than the 4.5" core though.

The thicket it gets the less efficient it becomes, plus it will obstruct airflow more. 4.5" is pretty thick. Plus the Procharger unit is designed for one in, one out.
