Paul, what makes you think the stock sidemount doesn't flow?

It has a full duct around it. There's not much blocking it behind.

How does your fmic flow? doy ou have a duct around it?

Applying the air takes the easiest path, wouldn't air flow around your cooler?

Also, it's blocked by the radiator and aircon radiator behind it.

PS: those who said that installing a new cooler does not increase power are wrong.

The stock cooler is simply a restriction to power. It is a bottleneck. it doens't flow enough. granted, cooling is also a problem.

Both of these problems are improved when fitting an r34 cooler.

you just said in the same post, that its not restricted at all, and then that its a bottleneck, and is restrictive....

No Dezz you've misunderstood his post.

Any intercooler is a restriction to flow of air from the turbo to the engine, thats part of how they work. Say your engine is running at 10PSI boost, and you standard R33 intercooler restricts the flow by 3PSI. This means your turbo is actually producing 13PSI to get 10PSI at the engine.

By installing the R34 cooler, as it is bigger, its restriction is reduced, say to 2PSI. This means the engine is receiving 11PSI when the turbo is running at 13PSI. And therefore making more power.

The other way an intercooler is a restriction to airflow is to the ambient air that flows past it. The Stock SMIC, although they have a small frontall area for the air to flow through, have good ducting that forces the air the flow through the cooler fins, rather than around it.

Many aftermarket FMIC have crap ducting, so air flows around it rather than through it. In addition, the air then must flow through the radiator aswell at an increased temperature.

For your info replacing an R32/R33 cooler with an R34 or ARC SMIC will not be counted as an intake mod, as the dimension (roughly) and the mounting location hasn't been changed from standard.

This is what i plan to do with my R32, as i'm looking for only 180-200kw in the foreseeable future, and dont wish to have to get a new front bar and cut holes etc, and for ease of installation.

Cheers,

Rhett

After reading xRHETTx 's post it got me thinking..

the factory positioning of a smic is actually more logical and effective than the popular modification of the aftermarket location of a fmic.

so a nice upgrade is to exchange my r33 smic with an r34 smic..

but personally i'd like to safely run my stock turbo at a constant boost setting of 12psi

is it safe to do so with this r34 smic? or do i need to search the market for yet another higher quality smic of the same dimensions to fit that same side mount location

Many have run 12psi with no problems but some have had failures on less boost than this. Its debatable but 10psi is about the safest max, you will only gain marginal power going from 10psi to 12psi anyway 5-10rwkw, as the turbo is nearing the end of its efficency.

cheers

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
