just a quick question coz i cant for the life of me remember the physics behind the heat transfer properties of different colours...will there be any significant difference in heat transfer between a cooler in its standard aluminium form..or one thats painted matt black?

Cars come with BLACK radiators.

If you use a spray system use a mixture of metho and water. There is a thread somewhere.

IMHO the colour is irrelevant. The fact is that the paint is providing another layer between the hot air inside the I/C and colder air outside.

Which means the heat transfer is not as efficient. Think of it this way, which is cooler for sleeping at night - a black blanket, a white blanket or no blanket? ...colour is not the question, number of layers is.

The cleaner the I/C, the more heat is dissappated. The best thing you could do for your I/C is to give it a wash with your mag wheel cleaner occassionally - just be careful of the paintwork.

none of the above....sleeping with 2 hot chicks on each side is wayyy cooler :whistling: (hope my wife doesnt read this thread)

Hahaha,

Colour having an effect relates to heat that comes from light/radiation (the sun) directly so if it is stuffed under the front bar in the shade it won't make any difference what colour it is. Hence the blanket colour description above.

Black absorbs the most light/radiation, it does not 'reflect' the light/radiation, that is actually why black looks black but lets not get technical...

Chrome is bright and shinny as it reflects a lot of light and therefore radiation, so if the sun happens to be hitting your intercooler, then it is better to be polished nice and bright rather than black.

My not so technical explanation:

black - absorbs more heat from the sun and therefore if subject to direct exposure...will raise intake temperatures.

Silver - may reflect heat from the sun ...but highly noticable by the police...who by freak of luck pulls u over for illegal modifications > this transfers to a heated arguement with the police about how u are just trying to make ur engine more 'efficient' ...to no avail and u cop a fine or worse a defect sticker...u then need to pay to have the intercooler removed and spend $$$ you dont really have which then transfers to a heated arguement with the wifey (especially since u rejected her proposal to upgrade kitchen cabinets on the basis of lack of funds) > which makes u get all heated up coz ur all fu coz u aint seein no heat in the bedroom ....

therefore in conclusion....imho ..silver transfers more heat :whistling:

    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂  
    • Is this a brand new LSD? if so, have you followed any break/bed in procedure for it? Usually involves heaps of figure 8 patterns, a fluid flush.
    • It's TWO steering wheels actually. 😛 one for each hand They are wheels, and they steer!
