R33 Intercooler Upgrade at VMS Melbourne (PHOTOS)

[WLD747]

Hi guys got myself a intercooler package at VMS and just thought all you r33 owners would love to see some pics of the work that VMS have done. This package has made a once sluggy r33 into a bullet and still more mods to come.

VMS is located in Footscray, Melbourne. See David or John if you would like a intercooler package. Just tell em Amit sent you.

Heres the pics below, Comments please.

with an intercooler package liket his r33 stock fan has to be upgraded to a new thin 16'' one. As shown in the pic.

not a bad pic of the cooler on the bar. Post more pics later.

Cheers

why do you need twin inlets on a gtst or is the car a gtr?

[WLD747]

twin is good reduces lag from turbo and goes through the cooler at the top and bottom. So ive heard.

first time I have heard of it I would have thought if it was good apexi hks or trust would use it any way enjoy

I've seen twin inlets on more than one GTSt.. are they really that beneficial???

It looks good though

[slayer_1971]

looks good....how much did it cost you???

[WLD747]

well this was custom installation and stuff around the $1600- $1800 mark. But its worth every cent when you hear the intercooler sound and when the car keeps on pulling you back with boost never dropping.

But they have other packages and cooler sizes going for $1200 - $1500 installed and tuned.

I think they split into two pipes just after the turbo so that two pipes go out the engine bay (out both the original send and return holes of the factory cooler) and into the new cooler. From a flow viewpoint, i can't see that splitting it can be any better than one single pipe.

When you split it so close to the turbo, the air effectively fills double the volume, which (when fluid expands to fill a void) will cause a pressure drop. So now we have less pressure (but more flow) along two pipes, with added turbulence at the split (remember this is why when we have a separate wastegate dump we join it back to the exhaust a fair way down from the turbine so there is no turbulence). Compare this to the pressurised flow of a single pipe - higher pressure, but no disturbed flow or turbulence until it reaches the intercooler.

So when the two pipes reach the intercooler, the flow does not have to distribute itself as much inside the end tanks, and it should in theory flow much more distributed across the IC core. However, this is where fluid flow research is at its best - i am sure that HKS, TRUST et al have done hours of flow testing to ensure their endtanks distribute flow evenly across the intercooler core. Many companies both local and in japan believe that this is the key to a cooler that flows well, cools well and does not restrict flow too much - end tank design. So now the single pipe IC has reached the cooler, and if the endtank is designed correctly the air will distribute across the core (with a fair amount of turbulence. This pressure drop and turbulence will occur with both styles of cooler.

So the charge of air passes through the core at a lower pressure and is collected at the other endtank, reducing the volume (to outlet pipe volume) and hence re-pressurising the air. Now what i am saying is a well designed twin entry should perform as well as a single entry cooler, but there is more scope for variation. This system would work better for a very big turbo, as it will keep pressures up and air flow speed up in the twin pipes before the cooler.

I'm curious about the dimensions of the cooler???

And were the endtanks cast or welded?

The cooler looks pretty sick, man... congrads

[WLD747]

The cooler dimensions and info are:

Garret Custom Intercooler - 700 x 400 x 75 ( I think it is)

[Guest INASNT]

this is the exact setup as nathan (dj lethal) got done at vms!

dont know why they keep putting 2 intake pipes off the single turbo.

ronin

I see you been listening at uni in your fluid dynamics class!!

[DJ_L3ThAL]

denham, its the same setup as mine coz it is mine, i needed to sell it for $$

[Guest INASNT]

oh ok, he made it look at he bought it off them
