Intercooler Test (Pics added Page 10)
Im going to be doing a back to back intercooler test on the 1st November.
My Radtec 50mm thick RS500 size against a 70mm thick Airtec RS500 size
The Airtec Intercooler has been modified so it has the same size pipes as the Radtec.
Will be doing 3 runs with the Radtec and averaging the ACTs and power then changing over the intercooler for the Airtec one and do the same test.
When my car is on the rollers it always drops power on the 3rd run due to high ACTs.
I just hope after the expense i get a good result lol

If you were testing on a car wich is at the limit/close to the edge you may have to alter boost accordingly..

Please remember folks this is a personal test for me and not a company test.
Its me that has had a intercooler modified to my spec to see if it improves my ACTs over my current set up.

It's 'suggested' by those in the know that the cheaper, heavier 'coolers always fair well on RR sessions, but not so well in the real world.

Yes id love to test the spc r back to back on this level of tune,iv got no doubts it will be better its just i dont think at this level it being better is needed as theres only so much cooling the acts need to work..
And as said by steve if a cooler works better on the rollers it will work better on the road..

Not necessarily. The heavier intercooler will take longer to 'heat up' so on the short bursts on a RR their mass and solid build will be in their favour. But on the road under sustained usage they will heat up, and not dissipate the heat away from the core as well as a lighter 'cooler, so could have a negative effect on the ACTs.

Theres no way you can replicate the air intake on the rollers as in the real world so once heat soak has set in theres no way of getting rid of it on the rr where as if your on the open road the acts will drop rapidly...

So you're saying at a high power levels ACT's dont make much difference wether they are bad/ok or good?
Are they being tested on an accel dyno? I wouldnt have thought that type of test would be much good as it's a quick up the revs an coast down.
Hasn't anyone got pics of the core's used on these coolers? IMO the core alone will give you a good idea if its a good IC or not.

I've found that life I needed.. It's HERE!!
out of curiosity, how much did it cost to get your cooler modded?
any pics so we can see the end result?
i run an airtec cooler on my car so i'm interested in the differance

Why not just shut the car off and leave the fan on for a few secs? ACT's will go back to Ambient in a short time i'd have thought? possibly quicker as there will be no heat passing through it from the turbo as there would cruising down the m.way. depending on your fan size of course!

To your other point about letting the acts come back down,well that is what we do when were mapping just shut of untill they are back to normal..
And thats my point you dont do that on the road do you???you have loads more air and just have to drive...
The point im making is if the car and tests with stand the dyno they will be as good or better on the road...
The rr is a dd mate so no run downs...

No im not saying that at all im saying in steves case at circa 430 hp where he now has high acts having an awesome cooler like the spec r one is over kill and imo the airtech plenty good enough..

Ah I see, personally if ACT's aren't the same as ambient then there is still room for improvement! I know your very unlikely ever to see ambient temps on a turbocharged car, but getting them as close as possible is worth it...if he improved his ACT's by 10 degree's at the top end flat out, that could be worth another ~10-20bhp for instance.
