LOL@Hanco that LOL@mario thats gonna LOL@Rat..... lol

oh ja , just thought id add , before the flaming starts..

iat will also depend on the efficiancy of your compressor (turbo), and ambiant temp. of the day.. so personal experiences may vary..

got that one 300, just looking for a comparison... kind of...

What you running at what boost? temp on the day you got that iat?

My IAT are always around the 32degree mark, this is on a hot DBN day.

running a hybrid t3/t4 , compressor ts04 (closest) @ 1bar boost (remember,im running a 3.0L V6)

temp was prolly about 25 deg.
wish i could tell you right now, but my cars not running at the mo..

Well, by the looks of things the intercooler and radiator combo is a good setup?

What Ive read on the internet on average your looking at between 30 and 55 deg. cel.

Or am I loosing the plot here. I know there is allot of factors to think about here.

Any opinions?

I think you loosing the plot .

The temp difference between between 35 and 55 is HUGE. Anything above 40degrees is too much, when footing it then it is a different story.

Do you remember the formular PV=mRT?? work out how much less air you will have for every 2 degrees increase in temp.

mmm ok so maybe one day I have to say this and I have been keeping quiet on this topic just to avoid confrontation...BUT

GARY IS RIGHT!

that is right gary, but that 30-55 is with normal FMIC.....

Not wid the combo. Thats the range I could find on the net.

So the temp 300sx is getting is bloody good.

OK now you are forgetting a few things here.

Lets take it like this:

The outside air temp = 25"C

It gets inside your bonnet where the temp = 28"C

Then it gets sucked in through your filter and down your CAI pipe to the turbo where the heat of the turbo pushes the heat up to 38"C

Then you push the already hot air through your intercooler pipes to a intercooler next to the radiator which pushes the the heat up with another 10"C

So now you get air running through the pipes that is 48"C which have a friction coefficient a lot higher of colder air, and friction = heat so lets say you en up with air that is 50"C going through your TB and then getting into the engine where it even heats up more!

That is just from the point of view that Gary and I will look at it. That is without all the mad scientist calculations to not confuse anyone!

(All of the above is not true calculations)

Nothing confusing me here, thats what I found on the net..... Thats all Im saying.

Hanco: Where do you get you temp from?

Mario as I said I am constantly around ambiant temp, 35 is high for me. On freeway driving I will average 28degrees on a normal day.

Seriously do the calculations, it works out that for every 2 degrees or temp you need to remove something like 6% of fuel to keep the AFR the same, I cant remember the figures exactly but they are HUGE.

Guys do this to save space... what is in the space in the bumper where a FMIC would go?? What are you saving this space for??

Just havnt seen it before. I just wanted to know what the difference in effectiveness it would be. Thats all. Was just thinking the amount of less pipping you would use as well.

I understand where you coming from. Thanx for the advise.

Yeah mario, you could always use this system and the go for w/m to help the cooling. When I use my w/m my IAT dropped down to about 18-20degrees at WOT.
