Intercooler plumbing design

Hi guys,

Does anyone have any input on my design?

The engine is twin throttlebody v6. The engine is offset towards the passenger side. Single turbo.

Im summing up a few options for cooling.

Ive spoken to PWR who think the best option is conventional IC before Rad before oil cooler vented out the bonnet.

With this setup the IC cold pipes will be different lengths if the IC is 1 in 2 out. Is this an issue? The pipes will be maybe 3-500mm different in length. Would a balance tube before the throttle bodies help to equalize the volume?

Another option is the same setup bu conventional 1 in 1 out IC then split the cold pipe in front of the engine to the throttle boddies, like reverse twin turbo non ICd LS swaps. Thoughts?

Thanks

Andrew

That would be a good order.

Slight difference in lengths should make not difference, just make sure you use about the same size pipe/hose work and try and make all the bends/direction changes smooth.

There are some horrible charge cooler end-tank designs, even on some popular 'coolers, and that is going to have a much greater influence on the airflow - keep it/them smooth with flowing bends for best results.

Still on cooling. Is twin in series oil coolers a thing? Mounted on either side of the radiator with their own ducts.

There are many applications that do exactly that. Some run them sequential - engine>1st cooler>2nd cooler>engine, whereas other applications use "Y" fittings to split the oil lines and run them in parallel. I would strongly recommend using an oil 'stat, to ensure the oil temperature doesn't drop too low. Maybe removeable blanking plates for colder weather/street driving? Don't forget, the longer runs will potentially require a size larger, or two, oil lines.

IIRC, it was Koenigsegg (yes, had to check that spelling) that added a further refinement by fitting the oil coolers into the same ducting that fed air to the brakes - the warmed air improved initial brake pad 'bite' and response.

Thanks mate
