To Be Honest, the stock knightsport IC does indeed work, however it is subject to heat soak, if you have any front vented hood or a custom intake duct made specifically for that IC, you will see lower water temps due to nothing in front of the radiator.

What i can recommend, if i didnt go to the water 2 air system is to,

A: Modify Bonnet to allow air to escape ontop of IC (Treat it like a Top Mount)
B: Construct a duct and drill hole to allow cold air straight to IC
C: Custom Fab a AEM Intake to sit outside your engine bay for the S/C System.

Lots of very usefull information here guys, thanks very much.
There are several other areas I need to address before going FI, clutch, 2nd oil cooler, upgraded brakes etc.
Overall do you know if these kits are as good as their advertisments say they are?

Depends on the particular kit you had in mind, generally japanese kits underestimate their potential to ensure you get your power figures.

What sort of upgraded brakes are u looking at? To be honest all you well need is as max pads+ braided lines, and rotors to slotted when you need to replace them.

It was the ProCharger kit I was looking at purely for its perceived simplicity & supposed ease of installation & removal, not outright power.
Brake upgrade would be just pads, braided lines & rotors to start with, maybe 4 piston front calipers further down the line.

Stock brakes are really good and more than adequate for street use. For track use I found project mu front discs and DBA rears with project mu pads all around.

This works for me and I really push by car when I am at the track. Good sway bars and suspension will help as well.

I normally do a mod and track it several times and then when I am comfortable with the gain then I look for the next mod that will improve my lap times.

As a next mod I now need better rear end grip. One option is a GT wing or create negative pressure with under body panels.

I'm pretty keen to tackle a S/C setup if I can get hold of a centrifugal unit for a good price. Something different to the turbo setups I'm used to.

Tofu, PM sent.

SKC I might have missed it, but is that coolant, oil or intake temps at 90 degrees? I hope that's not intake temp because that would be crazy high with an intercooler. Coolant for mine at the moment it's about 80-90 at night, during the day average of 95. And that's N/A!

PM Replied

It is most likely coolant temps, if you are getting 80-90 at night, i presume this is stop go traffic?

Cous if it is open roads, there is something seriously wrong with your cooling system.

I have a oil temp gauge at this stage. In normal driving the oil temp will be around 70 degrees and with a bit of hard driving it will move up to 80 and may get to 90 on a hot day with hard driving and then sitting in traffic.

I most instances it will sit at around 80 once it has warmed up.

There are better ways for more rear grip than a massive wing... Are we talking rear grip around a corner, corner exit, or straight?

On the straights the car is perfect however I need grip around high speed corners and undulating tracks. At this stage I am looking into a splitter that will restrict air flow under the car thus giving negative pressure under the car leading to more grip.

I doubt u will reach speeds to make it truly effective.

I suggest messing around with suspension settings. Also adjustable sway bars may help.

Also...wider rubber.

I'm sure u will find these more effective than an aero peices at the speeds we are talking about

Yes the coolant temps I mentioned are stop go traffic that I get at the moment in Sydney's current weather.

Splitters would make a difference even if minor and barely noticeable, and of course it's effectiveness really depends at what speeds you're going at. Obviously the faster the car is moving, the more it's effectiveness. Is it money well spent is a different question though, I'd rather go with wider tyres

to combat coolant in stop and go its the themostat you want to have a look at, a upgraded radiator will simply bring down the heat faster when you get good cruise driving.

So you'd want to tackle fan speed and themostat for a street driven car first and see how it goes.
