Is this Treadstone intercooler good for LT1 application?
What do you guys think of this for an Lt1 for ultimately 10 - 15 pounds boost with goal of 500RWHP? My procharger intercooler reportedly is losing 3-4 pounds and will limit further boost increases efficiently. The C5 procharger kits make more boost with larger blower pullies, so the 3 pound loss seems right on target.
I am trying to get up to speed on critical specs and what type of CFM rating would be needed for 500RWHP (600 @ crank) application.
Single Turbo Intercooler, Chevy, Corvette, GM, Viper...
All you single turbo, and supercharged Vette, Camaro, Viper, Trans Am Guys, this is the intercooler you have been waiting for. After popular demand and lots of email requests we have finally came out with a single inlet center top outlet intercooler! Treadstone Intercooler features superb quality highly efficient bar and plate construction. Our quality cast end tanks ensure evenly distributed airflow and low-pressure drop. Our intercoolers are now pressure checked to 150psi and come with a 1-year warranty against manufacture defect. This intercooler was used in various single turbo applications such as, Corvette, Viper, and Camaro....Able to support upwards of 1000HP.
Core Size, 25" X 6" X 3.5"
1-3" outlet and 1-3" inlets, passenger or driver side
Outlet is angled 15 degrees back towards engine
1453 CFM flow rate
968 HP efficient
1.5psi pressure drop at 1453cfm

I think it will flow enough but getting it to fit in the nose of the car may be tough since its 25" wide. If you can get it to fit, that would be a huge step up from where you're at currently.

Money Can't Buy Happiness. But somehow it's more comforting to cry in a Corvette, than a Yugo.

I have been looking at the kits that A&A Corvette does for C5's. They have a ram air system that as best I can tell the intercooler sits about 6'' in front of the condenser and sticks out underneath the nose with an airbill. Need to look at ground clearance.
The radiator opening underneath the car is about 28 inches. It looks like I would need to cut the top shroud to get the intercooler as far forward as possible and try to maximize gap between intercooler and radiator.
The thought would be each would have its own pseudo clean air path and their own scoops. I need to see how to route the inlet pipe from passenger side.
I am still looking at the whole setup. It could range from rather straight forward to a complete hack and fab job - main issue is to get it forward as much as possible and try to have ground clearance be at least an inch or two more than the existing factory air dam.

I'll have to take a look at my front end. I have the car on jackstands, so that shouldn't be too difficult. I have a few extra coolers on there so maybe that's why I don't recall seeing that much space under there.
Where did you get the idea that you are loosing 3-4 psi with the ATI I/C? What blower and what pulley? If you have a D1 pullied up to MIS, then I might understand the 3 psi drop. But on a fairly stock car that 3 psi drop across an IC will hardly be noticed as the engine restriction will absorb that quickly.
The best route to go is to measure the delta P across the core, and then you will have your answer without guessing.
The ATI tech said that the LT1 intercooler is losing 3-4 pounds, and recommended going to meth if stepping up boost.
Bob from EPP posted a few weeks ago that he did not have good success increasing boost on LT1 and only increased air temps.
The core size is small: 13.5 x 6 x 3.
My pulley size on a P1sc is 3.6 inches.
I asked the C5 procharger guys what they were seeing, and the consensus was
2 LS1 cars: 10 PSI with 3.85" pulley
LS6+Headers/exhaust: 8.5 PSI with a 3.85" pulley
I would expect these cars to be in the 11PSI range with a 3.6" pulley setup. Also since the LSx heads flow better, the LT1 should see even more boost at the manifold.
Do you have a good trick of measuring boost between the compressor head and intercooler?
I can post some C5 pics of what I am trying to do, how do you guys do it?
