Im amazed everytime that the std bumper fits over all of that. Did you have to cut any of the bumper internally?
It would like to do one about 3/4 of the height of yours to leave a gap between that and the aux rad. Might contact the seller to see if they can make some other custom sizes. Overall a 100% improvement over the standard x-member pipework and joints.
If you can wait a week or so Matt, I'll post some pics of the intercooler that I am about to install.
It's not quite as tall as Bo's (looks quite modest in comparisson) but may not require as much work to install.
Just waiting on a cross member that Bo is sorting for me and then will have to make up a bit of pipework to suit.
yes that is very nice! Good work. Now in oder to have the oil cooler Duct allmost in place the right inlet of the IC should be welded in another position? What do you think?
Yes that's true billman, That would solve the oil cooler duct issue. I don't think its worth the hassle though.
Took ithe out for a proper thrashing tonight and the oil didn't get any hotter than normal.
Also, there's plenty of space to the left side to make a different shaped duct for the cooler.

Pressure drop, when fitting a larger intercooler there's more air space to fill inside it by the turbo charger. If the turbo can't fill it quick enough over the pipe length / volume space you get a pressure drop.

Hence my mantra you can have too big an IC.
No you don't get a pressure drop with a large IC. A too small one would get you a pressure drop.
A large one will give you a bit more lag (because there are a little bit more volume to fill), but no drop in pressure

Can you explain how you came up with this "theory" Roger?!!! Jamo is correct!

I think your find Jamo is right here,
You are right about the lag as the turbo is going to have to fill the volume of the intercooler.
You really want a intercooler that will maximise cooling efficiency, minimise pressure drop. So to small is going to be usless any way!
Right air from the turbo is passed through core allowing heat to dissipate. The larger the core area the grater the loss. But equally a lager core will cool more air. (you need to create a equal medium)
resistance of a standard one could be say .05kg/cm2 at 1.2kg/cm2 of boost but the larger you go the bigger the drop.
Also you have to add the resistance of the pipe work
Hense reverse inlet manifolds

just a small question... would the ic be more efficient if it was longer rather then taller? as u would get more air passing more of the ic? it made me think because half the ic is getin blocked by the bumper/ number plate.

Not 100% sure about "equal medium". Thinking about cross section of the IC?

Here I don't follow you
Lets look at IC's as pipes: Would you say that a small pipe has less resistance then a bigger one?
About drop you got it right in that the pressure will drop, but not because of resistance. As the air cools it gets denser and takes up less room. Pressure drops, but amount of air is the same. This is the IC's main function
Can you explain how you came up with this "theory" Roger?!!! Jamo is correct!
I'll try:
The turbo will deliver about the same amount of air independent of IC as long as the IC isn't so small that it becomes a major restriction (cross section inside IC is much smaller then other pipework) Agree?
The turbo will deliver most air when the resistance is as small as possible. Large short pipes and IC's with large cross section has the smallest resistance for a given amount of air. Agree?
(Going too large on pipes and IC's would of course at the end be giving more lag then the gain in smaller resistance could justify)
When the turbo deliveres the most air it will also deliver the highest pressure in the inlet manifold. Agree?
So as earlier said the only pressure drop a large IC will create is that as the air cools it gets denser and takes up less room and the pressure drops. The amount of oxygen would be the same, but in a smaller volume and therefor making it easier to get the oxygen into the cylinders. This is the IC's main function
