Whats The Gtt Standard Smic Good For?

[rice_me_up]

hey all.

did a few searches with no success.

Well now. i know that theres someone on here who has a 32 or 33 gts-t that uses the

r34 gtt standard intercooler, and is running approx 200rwkw.

the point is how much can they handle? im going to be running a garret gt2871r and usual support mods.

ive been told to expect about 250rwkw running 23psi (i know it alot of kw for the rb20 and that its gunna cost a bit).

i would like to run a smic so it appears to be stock.

cheers.

It's not going to be good enough at that boost level. I had 190rwkw with it and that was fine but I wouldn't go much higher.

Remember to a certain extent, an intercooler is just a heat sink and if you have a small one you will get heat soak that much quicker.

The GTT intercooler is efficent upto 200rwkw and a good upgrade for a R33 GTS25-T if you dont plan on upgrading your turbo

[Sydneykid]

There are really 2 things to consider, temperature control and airflow;

Temperature control, 200 rwkw is no problem, we have seen 215 rwkw which was OK on normal day. But in traffic on a hot day, it simply wasn't adequate. On the circuit for a couple of laps it was OK, but any longer and it heat soaked noticeably and started to knock.

Airflow, 200rwkw is no problem, we have seen 215 rwkw at 2-3 psi pressure drop, any more and the pressure drop skyrockets. This is OK as long as the turbo has excess capacity. But when you want to use the turbo to produce its target airflow you will be compromised by the capacity of the core.

another option to make a front mount look a bit less obvious is to not cut a big whole in the front bar, and paint it black, or put black mesh in front of it.

[rice_me_up]

yeah. ive heard about painting a front mount black. i reckon it will be the way to go. i hear its better for heat transfer? sort of makes sense to me... but would like to know if its definately true.

thanks for all of your help guys.

cheers. james.

[mad082]

painting it will reduce how well it cools. and putting mesh in front of it lets less air to it. (only a bit less). so either way is going to reduce how much it cools. i'd probably go the mesh route over painting. with the mesh, the look depends on which way you put it. most mesh you can see though it better at a certain angle, so you'd have that way pointing down so it is harder to see through... if you get what i mean.

[Abo Bob]

There has been a few very indepth technical discussions on here about painting intercoolers black. The general consensus was that it wont much difference either way as long as you don't put too much paint on.

That's my thread on the subject but there are others.

[rice_me_up]

indeed, i do know what you mean. like the glossy side has to be facing upward as to make it dificult to see.

ill investigate further. does painting it make a huge negative impact on cooling? or is it miniscule?

still deciding. thanks for your help mad082.

[mad082]

as abo bob said it depends on how thick you paint. would also depend slightly on what sort of paint. a cheap water base paint would affect the cooling less as it is thinner, but would cook off pretty quick. after reading most of the link i'd have to suggest to look at getting it anodised. buggers me where you'd get it done though.

but someone did a test and said that the temp went up for every coat of paint that went on.

Remember the r32 gtr intercooler is painted black from the factory.

In the book 21st Century Performance they found removing the stock black paint from an r32 GTR cooler made the cooler work LESS efficiently.

I think black paint would be a good idea if you can apply a nice thin coat (and only 1).

[R31Nismoid]

Or just get some wide spaced mesh, spray that black and it'll do a reasonable job @ hiding a silver cooler.

It'll look similar to the radiator really and pretty well conceled

Why worry about stock look anyway? The legalities? Or some other reason that i cant think of?

If it is legalities, your illegal and you'll have changed turbo, injectors, ECU etc

So its not really gonna matter.

[rice_me_up]

well to be technical ash, I wont be illegal, my car will be...

and if the average Mr. jack can't tell its modified then that would please me greatly.

everything that gets done to my car will be hidden... so yeah...

does it make sense or do you reckon Mr. jack will be able to tell?

cheers. james.

[WogsRus]

Actually anodising can be done by youreself. i know Bunnigns use to sell a product that did copper and steel. i presure it couls be used on alluminium. It will make it go black. Check it out.

Most officers know these days.

There are virtually permanent, random inspection stations, going around Vic

Go around the wrong corner on the wrong day and you'll get pinned. Its very hard these days.

You'll find most normal officers know whats going on in Vic with regards to mods etc

Technically you are beaking the law, so your illegal (in a sense)

You'd be better off getting an air dam to cover between the front lip & radiator so that people cant see whats beneath it, as your going to be using non-factory piping anyway

OR use a GT-t airbox. They flow quite well from all reports, then you make yourself harder to be picked again

Umm, i think you will find its for an anodised "look".

Anywa, its winter, so that means you intercooler woll be silver for about 3 months, wet grimey roads and dirt end up with your cooler being a darg grey anyway

[rice_me_up]

fair enough. just to make it clear ash, i wasnt being a smart-arse in regards to the "technically i wont be illegal" thing.

i still have the standard air box and i wont change it unless the gt-t airbox flows better???

i geuss the only way to get around this is to get an engineer's certificate....

cheers guys. James.

I know

Im not sure if the GT-t airbox is bigger, but i think it is from memory.

Engineers cert wont cover it

You need emissions, thats expensive

[mad082]

i must say i'm glad i live in qld. they aren't that bad up here....yet.

Changing up to an r34 gtt intercooler on an R32 or 33 is a legal modification if you read the regulations carefully. It is in the same positiion and is of the same type.
