Which Intercooler For Track?

[Chris32R]

I'm currently sourcing the final parts for my R32 GTR turbo upgrade. I am going with -5 turbos and am stuck on what intercooler to go for. I have done some research and have read that standard cooler is good for upto 350kw which is around the power i'm chasing. The problem is that the car will be used for track days so I don't want to run the risk of having too high of intake temps after a few laps.

Will the stock intercooler be ok on the track with 350-360kw?

If not, what do you reccomend?

Cheers

Factory.

I can rattle of half a dozen circuit cars, 380rwkw - factory I/C.

Maybe have a look for an R34GTR cooler, they seem to be a little more efficient... they have a handy little fitting for an air temp sensor too..

The ultimate set up for -5's and circut work is the ARC twin entry 70mm cooler. I believe the Hi Octane 34 runs one too. Around 1700 USD

Or you could run a water spray kit to keep the intake temps down.

Wow I knew the factory intercoolers were good but not that good lol.

What benefits would there be going with an ARC twin entry over factory with water spray kit?

Do you know any water spray kits that you would reccomend?

Thanks for the info guys.

An intercooler is a very basic air to air heat exchanger. The ARC cooler is superior to the factory design in a couple of areas:

Less restrictive flow path and less pressure drop

More effective and efficient at cooling the intake charge

Same or better flow through of outside air through the cooler... this helps to keep the radiator (water to air heat exchanger) cooler.

Honestly, unless the car is a heavily used on the track, your stock cooler should be fine... if you live somwhere hot, then invest in a cooler spray kit.

I don't know of any off the shelf spray kits for intercoolers, but it's the kind of thing you can do yourself with a couple of garden nozzles and a spare windscreen washer bottle- OR use the rear washer motor in your existing washer bottle (who uses the rear washer anyway??) Just need to get a little creative.

If you must buy a kit from japan that is...

Awesome thanks everyone. Saved me a bit of cash on spending big on a new cooler.

Thanks guys much appreciated!

Are you running stock internals?

Na mate. Arias forged pistons, 33R crank, eagle rods in a sleeved block.

Will be going with that cusco setup unless someone says otherwise?

forget water spray for the intercooler and go for a water/meth injection kit

you will actually get meaningful gains over the i/c water spray, which wont do much unless its pretty much constantly on, which on the track will mean water going under the car and potentially under the tyres.

I've got -5's and am running stock internals, with stock R34 cooler. What difference will this make??? I only run very low boost though as its my daily driver and I can't afford a rebuild at the moment.

Just did a little research on Water/Meth Injection and seems like a very good way to go with impressive gains in power, intake temps and the reduction of knock in an engine. Do you know anyone who does these in Aus as I would be very interestred in possibly giving it ago.

Thanks

Your tuner is going to need to be familiar with setting up water/meth injection. Otherwise your gonna have research it and work with him on tuning the car. Spend a couple of hours reading up on it and how different kits use different methods of controlling injection flow etc... The most well sorted setup i've seen is the aquamist hsf-6 which is easy to setup and tune, has progressive control, fail safe and reliable. It's not cheap though at about 1k, worth the extra coin over the cheaper setups in my opinion. Cheaper setups will do the same job just not as well.

Not too sure if this theory is still used but, I remember reading an article on intercoolers and they explained there is 2 types.

One is "Bar and Plate" and the other is "Tube and Fin"

From memory, Tube and Fin gives better cooling and Bar and Plate gives better air flow. (I think that's how it goes?)

Having said that, since you want to track / circuit your car, you would probably go Tube and Fin as it give better cooling because you will need it as you spend more time on the track, car will be exposed to a lot more heat so you would need good "Cooling"...

If your GTR was designed for Drag Racing, you would go Bar and Plate as you won't spend too much time on the track... Depending on the car, you'd be on the track for no more than 15 secs.

You want the air flow straight away.

This my not be the case these days as I was talking about this to a friend a good few years ago...

Ash might want to clear this up...

There is a thread here about the two types - CBFd going into it again

Good to hear, then at least the theory I read still is in practice... I guess.

[Chris32R]

Any idea where i could buy the aquamist hsf-6 from in AUstralia?

Cheers for the info.
