Twintercoolers, i dont understand
Discussion
Maybe not quite twice the cooling, as there's a bit of efficiency loss by mounting an intercooler in front of the existing one, but it will work.
There'll be greater pumping losses to account for too.
It depends whether one uprated intercooler cools more of the charged air than 2 standard type ones. And that depends on a number of variables.

Yeh suppose, intercoolers are a fine art. Doesn't make sense in my mind why anyone would block one intercooler by another, i get the thickness makes it more efficient. Have a 5inch thick cooler in the shed bloody massive thing rated to 1200hp+ but that will generate so much lag due to the size. So would the twintercooler setup be similar creating lag?
Probably. While I should say that I'm no expert, logically lag must be caused by a number of factors:
Turbine size i.e. bigger turbines take longer to spool up on a like for like basis
Length and size of the pressurised inlet pipework, including intercoolers etc. Air is also springy, so there's a small delay in pressure changes due to this.
There's quite a science to it, maybe someone with direct expertise will offer a better explanation, rather than me trying to dredge up a university education from over 20 years ago

.The Audi TT mk1 has 2 little coolers, 1 under each light, I think this was packaging driving it, a good upgrade is a front mount intercooler from the likes of forge who would have developed it to suit the application balancing size and cost.
There are coolers and coolers, an rs500 cossie one looks very like the spec r one which runs a garret core but the spec r one is massively more efficient.

I get the different designs of coolers, pressure drop from inlet to outlet etc. I disagree on brands, shouldn't just buy one intercooler over another because of the brand. The one in the shed has no brand, theres no markings on it at all. Its done 900bhp on an evo, tested to over 4bar pressure with little pressure drop, it cost £50 altogether. But this threads not about brands
The RS 500 is a style, not a brand. My point about the spec r was not meant to be brand related, it is about the core being bar and plate which is more efficient, this can lead to not needing the same size.
Have a look at Rod Tarrys 210 mph Sierra cos, that uses the bar and plate core as it gave far lower intake temps for the same given space.

Fine for pressure drop. But what about cooling?I've seen coolers perform awfully. Usually cheap tube and fin coolers. Which perform worse than OEM.
