Intercooler Advice

[maccattack]

Hey all.

I'm about to start modding my car again and am changing my high-flow turbos for a couple of the new T28-10's.

While I'm at it I will be changing the intercooler from stock to a new Trust cooler.

I was going to go with the Trust Type 23 - 302x600x115 (3 core) however my mechanic adised I should be going

with the Trust Type 24 - 284x600x76 (2 core) citing that the larger cooler restricts airflow to the radiator too much

and that the Type 23 is good enough.

Experiences - Thoughts???

Thanks

i would tend to agree. 76mm is still quite a thick core. and going to 115mm will mean practically no airflow is making it through your intercooler and air con core to the radiator. personally for anything up to 350rwkw I'd be happy with the 76. if it's more power than that you're after then the big core may be a good idea, and a new radiator wouldn't hurt either

[paulr33]

end tank design, fins, the core and pipework layout are more important than the core size

its probably not a big issue

Cool, thanks guys

i upgraded from a stock gtr cooler to and avo 100mm cooler and straight away i noticed quicker throttle respone

[noone]

Would a clean undented fin 32 GTR intercooler be better than a 100 mm thick aftermarket core if its got fins that are dented a bit an kinda closed up doesnt leak but looks shitty an I think might be resticting flow a bit.

Anyone got dimensions of the stocky?

Might be able to get a good condition stocker cheapish thinking it will make a good stopgap till I can source a ARC or something

Been having some cooling probs so thinking the thick core might not be helpin

haha lol.

yeah go with the thinner one. it wont overheat on the track as much.and besides a thinner one will have more air going thru it so it probably will work the same lol.

[T04GTR]

the reason there are such thick ones is for drag racing wher the sheer mass of the things is where the cooling happens. rather than relying on a volume of air going thu it.(still gos thru)

interesting note. on our race supra. it had a 700x300x76 cooler in it. 22 row. it used to overheat. so.. we cut it inhalf. to make a 700x150x76 core. 11 row. now it doesnt overheat and made NO DIFERANCE to inlet tmps on the track.

My idea of intercoolers has always been to get the smallest you can get away with for your application, the bigger the intercooler gets means more volume that the turbo's have to fill up with air before that air reaches the throttle body and hence worse response from off boost to on boost

ARE can run some calcs of ur setup and come up with the right sized cooler for your needs. $90 for it, and u get $50 back if u buy one of their coolers (which are only $1500)

I'm convinced T04GTR that most of your posts, while factual sound, are bashed out, while coming down off a heroin hit. Your English is completely "EnGrish" i love it.. keep up the good work!!!!

or if you're nice he might just do them for you anyway...

90mm ARE is sweet

a decent new jap one is only $1500 new, ARE are spin doctors.

We just replaced the 78mm generic tube and fin cooler one on cats car with a brand name 115mm unit and repeated runs on the dyno show the advantage of having larger cooling area, there is far less heatsoak after 10 or so runs. This combined with phenolic intake gaskets has been quite suprising.

you seem to love your jap 'brand names' alot dont you and your fast to beat down on the aussie gear

hows the response changed of the car with the larger cooler?

[Ronin 09]

well they may be the same money as a Japanese cooler but I'm willing to support the Aussie team at ARE

after all it's a lump of aluminium.

note mine's a tube/fin 90mm ARE made to order through discussions with them.

service means alot to me too.

[noone]

Living in Darwin I have come to understand the TRUE value of service

Will be looking at a new cooler soonish might have to give ARE a call.

Had planned on maybe an ARC or something

i do because we get fed a lot of baseless shit..... a local guy in a shed struggling to make sales needs a good line.... do a bit of back ground work and you will soon find the facts behind the product, where it comes from and whether or not it is as good as the line you were spun....

as for response after a quick tidy up it was barely noticeable, actually far less than i had expected.
