yeah i was like wtf when i saw his setup...

maybe he turned the core upside down or something...

the reason he Beef did his intercooler piping like that is so that the air

that goes into the throttle body is cool, as it doesnt pass behind the radiator like most kits

which makes the intercooler piping warm/hot. The way he did the pipework is really good.

it might help it a little bit.. but it still passes over the hot engine, heating it up again.

ultimately you want a custom/gtr style plenum that takes the air in the front of the plenum, and doesnt pass over anything warm/hot.

like this..

ever touched a top radiator pipe? the one thats basically touching the intercooler pipe on the photo you posted.....they get farking hot :woot:

I don't think it really makes much difference..the air is travelling pretty quickly...so its not going to get much chance to heat up

Ive seen an R32 do the pipes like that before, very very nice IMO.

Here is a thread from the Stag forum.

I would have done it like the guy above, but that way uses a few more pipes etc and would have ended up costing me a fair whack more, as i couldnt retain ANY of the stock piping.

id dare say the rocker covers get a tad hotter than a radiator hose, not to mention a fair bit more surface area.

there is going to be hot parts where ever the piping is routed, but minimising the length/hot points it passes is ultimately going to give you the most power and response. :woot:

but with beefs way it passes over the engine before the cooler and heat transfer via convection (dominant mode of heat transfer) is proportianal to the difference in temps.

so as the hot pipe passes over the engine it doesnt absorb as much heat as the cold pipe going over the engine in the normal setup.

if the air collects the heat on the hot side, it still gets cooled by the intercooler. if it is heated on the cold side, there is not chance for further cooling.

id say the effects would be fairly small, but the theory is there still

yeah, but then it wont cool down to as low a temperature as it passes through the intercooler >_<

either way, its good to see people not taking the standard approach to engine mods..

i was wondering if it had any affect on lag or anything as opposed to the tradtional RB25 intercooler setup.

it seems to use 45 degree bends, and long radius 90 degree bends which could help a bit with air flow, rather than the big U shape the typical kits have.

care to elaborate on that, beef?

well the guy who fabricated this set-up said that the traditional "U" shape set-up had a hell of a lot of bends.... he said he has designed a lot of intercooler set-ups with the straightest possible lines and also with the turbo side entering on the left and right of the cooler to see the effects of both.

This was the best he came up with, it is the straightest lines possible on an RB25 and also the pipe going to the intake is marginally cooler when getting to the intake...

his words "this is the perfect, most straight custom intercooler piping ever created for the rb25" :laugh: ha ha he has a big ego....

but i think its justified

Hey Dezz thats the exact kit im after for mine how long did it take you to do and were there any dramas involved? My car is a series 2 as well What did you have to cut out of the front bar?

Cheers

Hi there this is my setup everything went in really fast,piping ,fmic just had a prick of a time with the high mount manifold ,so i bought a few ss bends off ebay and made the rest myself this car really kicks as i live in the bush dont know what power it has never been dynoed a friend "reckons " it has well over 220rkw but guess only dyno results tell the real powerpost-30197-1158712585.jpgpost-30197-1158712635.jpg

I don't see whats wrong with the pipework going near the radiator, the pipe gets hot but air is pretty bad at absorbing heat, thats why the intercooler is designed to give a large surface area because it needs alot of air passing through it to cool the intake temp down.

Even look at the CPU cooler on your comp, same principal, maximum area (plus a bit of turbulence).

If air was effeceint at absorbing and losing heat we wouldn't need intercoolers, just run a pipe along the front of a car would be all.

Hey Dezz

Could you post some pics of your intercooler kit with the bumper on??im thinking of going for that type of kit aswell instead of going for the usual hybrid, chinese piping kits etc etc

The pics i posted were the blitz kit on my mates car. We're installing my kit this sunday, so i'll try to take some photos throughout the process and put em up.

Here's a photo with the bar on

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
