well i always thought of da v/top mount coz of dat fact ur awayz getting ar in even if sideways + shorter pipes + more room for MASSIVE radiator nd twin fans (tripple fans ? :) )

but den again wudnt realy want 2 cut bonnet up nd access for engine wud be a lil bit limited

ok lets switch this thread up a bit... we in theory know that this wont work well due to the amount of heat and air blockage...

Now lets throw in the AC cooler... how would you fit that into the equation if removing it is not an option?? i was thinking of pairing the AC cooler and the radiator together on the bottom of the V-mount... with the cooler in front of the rad.

mount it underneath the radiator so that gets bashed before the radiator does :laugh:

ok final solution... sorry would have got pics but i forgot to take my camera.

but the run down is a comprimise and cost effective...

GTR intercooler mounted upsidown where the radiator sits, radiator mounted behind it (AC removed for other reasons) gotta see it to appreciate it, the piping is so short, everything is protected by the core support and all at almost no extra cost... ill try to mock it up again tommorow for pics... but i might have to wait till i get some parts from the US and complete the install...

actually it's quite scientific as to why intercooler belongs in front of rad. It's called counter current exchange in animals (which is where I learnt about it anyway) it's basically the optimum way to transfer heat between fluids. The underlying principles are well described here: http://en.wikipedia.org/wiki/Countercurrent_exchange

Shortening the length of the pipe will reduce lag, however you are sapping the IC of most of its efficiency, it is only cooling air around what? 40 degrees? as opposed to your radiator which is cooling water from around 80. You would basically reverse the counter current exchange.

basically what was said a page or two back... but thanks for the recap....

I'd like to see this new setup 4d-whore. Sounds cool.

If you WERE going to keep the aircon with a V mount, I would say it'd be best to put it right in front of the V mount. i.e.-

_

V

r

e

s

t

of

c

a

r

The air condenser isn't very hot after all, and due to it's size wouldn't block enough air to matter much at anything over 20-30kmh - maybe under it would make some difference however.

I think so long as air is being forced into each cooler properly with baffles/air dams it'll be ok. Without that I don't think it'd be anywhere near optimal efficiency. If you're not going v mount and you want that little extra you should try a small lip (like garden turf size) below the engine as well.

haha yeah its pretty thin but unfortuantly we had a conflict cause one system was R112 and the other was R134 or somthing... i wasnt to keen on keeping it anyways since it weighs like 70lbs... thats about 5 horses right there.. and it was just annoying i dont mind not having AC i told my jap friend that if he wants it he can transfer it himself haha... the japanese are pussy's when it comes to hot weather and rain...

i hate the cold myself...

they cut the entire core-support out of the car to do that... i was moving my dummie rad and core around and just couldnnt see any better way to do it then the setup i picked... vmount is more efficient but the cost changes a bit... but i think the response will be the same between the two

      Yuck. But it's kinda the same principle, moving timing around to make car run bad but sound good.... I went for a more spirited tuning drive to iron out a few things. Car no longer stalls, and it loved to dip RPM low when you clutch in. After tuning this (and the 4-5 tables that HPTuners/LS1 OEM ECU wants for idle air correction) it's now behaving somewhat normal. All expected because there's a new TB, new Intake manifold and that new TB which is 102mm vs 78... has an entirely different IAC passage which is smaller because ????? Unfortunately at this point I went to make further fine tuning changes to avoid it flaring up, you know... _tuning_ the HPTuners dongle died. Well to be more accurate - The USB cable died in a fashion that anyone who has ever charged a phone will recognize. After the app demanding I resync it 50 or so times (which all 'succeeded' but all failed) the device does not want to sync and I've logged a ticket with support to see if it's fixable. US Support said it was a 'storage issue' but after removing the SD card inside it and formatting it/fixing it the issue does persist. Unfortunately usually the fix is "Turn in your old dongle and pay $700 for the upgraded one" it's cheaper because I get some free licence credits I unfortunately don't need. However I'm 10 minutes down the road from HP Tuners AUS/VCM so at least I won't need to post it, and logged a new ticket for support over here. Definitely drives different. My SOTP dyno believes it's probably making 310-320kw instead of the 280 before.  It scrambles for traction a little now whereas it previously different. It drives like a bigger cam car up top even though the cam is smaller, likely due to the cam not being advanced 6 degrees. The timing is deliberately low and the fuel is very rich so who knows if this will improve on the dyno. It may, imperceptably. Also funny is removing the pineapples definitely makes the car squat more and axle tramp less. So this behavior of having more top end, squatting more, and scrabbling for traction more makes me think = more power. But I could have just been sitting on the threshold of that kind of behavior before. Time will tell if my butt dyno is calibrated right. I need the exhaust leaks fixed before dyno tune for obvious AFR related reasons - I repositioned the pipes but I'm not confident it's fully sealed even if it is better. At least the car does drive around while I cannot tweak/tune it for now. And I have aircon again. medium success!

      Don't use that manifold. Please don't use that manifold. Sunk cost fallacy is not worth the later pain. None of these will be relevant to the change that will come from the different turbo and manifold. As in, the effect of the exhaust will be nil, regardless of what else is changed. And all the cam and fuel system stuff is not changing either way, so has no effect. The turbo and manifold (and to a small extent the wastegate)....big change.

      Just wanted to say thank you for your input   my man (lead mechanic by trade) and I have done a heap of work as you can imagine just to make the hot side work with the dump pipe, stupid massive intake on turbo, trying to get the waste gate on was not fun.  I’m kinda getting to the point where I don’t know if I try and make this work and not throw all this cash and time away or do I scrap the lot and start again? the Apexi I’ve got was tuned for a few slight differences:   Tomei pon cams (mine are stock neo) Turbo smart 38mm external waste gate (mines 45mm replumbed) with stainless screamer pipe  3inch turbo back exhaust with high flow cat Sard 800cc top feed injectors Sard adjustable fuel pressure reg

      Out here E90s are the cheapest way into a sporty-ish car because everyone knows just how expensive the repairs can get. 8-10k USD for an automatic 335i.
