Default Limits with factory IC?

Cut the story short, I have a 924 project that i plan to frankenstein with a mix of cgt and gtp body parts with. And the engine will be getting some big boost.
I know i probably will not achieve over 400hp out of the engine. But will the stock IC with modded end tanks be sufficient enough for track days? It will have proper ducting to it also.

Hi.

One serious racer here in Sweden with a very Quick 951 has the stock IC with about 430hp. It has modified end tanks and ducting like the 968 TRS. He keeps up with 997 cup cars.

I did 444 ft/lbs of torque with my 3.0L with the LR stage 2 at 15lbs boost running Petro Canada 94 octane.
We didn't have any fans blowing on the car either. Was a hot day too. Guessing you would mod the end tanks in the same way.

Similar way. Would try to get it 2.5" though.
This is just in the making. Thinking a few things though.
The car is already on the hoist. There will be a fair amount of body work. As it use to be brown, now it's black... and it was a **** spray job.

Got some pics Pauly? Sounds like a cool project, I absolutely love the look of the old factory race cars.

I'd be more worried about heat soak than throughput. I made 450hp and 473tq to on a dynojet with a bone stock intercooler.

Not yet. I'll make a build thread, but probably in the 924/944/968 section as it will have the 2L engine ect. But the knowledge of boost is here. so i might just do it here.
I might do one on the PFA.
and probably 924.org.

At the moment i've just go it on the hoist and it will be a weekend project. It will take a long time.

Check out Ideola's AWIC for the 924T...sweet piece, but a little pricey.

If you are doing a sweet project maybe now is the time to fit a post-IC hood vent ala 968TRS...

I already have the factory cooler from my car. Easier to mod the end tanks than play with other solutions. (should have done this with my car lol!) but i didn't have my shop available to use my big Tig like i do now.

Bonnet vents isn't a big deal at the moment. they'll be there.

At the moment trying to plan what i can use and what i shouldn't use.
Where should i spend the money first ect.

951 intercooler is tried and tested on 924 many times, it is more than enough for 350 hp. Any top mount IC is not enough.
