How to reduce Air Temp

[BIGBOYQ]

Hi,

I have a E89 28i - so N20

I suffering with high Air temperature I been unable to find an induction kit, so will an K&N Filler panel help to reduce Air temp?

What other options are there.

Maybe the 3 series forum will have some info for you?? Not many ppl on this forum for the N20.

Air intake temps? Bigger FMIC or Meth injection.

Well you may know that I have a 2 ltr turbo - and with some recent events I have noticed the car suffering from heat soak, this reduces the car performance.

I could not justify the cost of larger inter-cooler as you talking best part of £1,000 and I would be an gunie pig - as not many people have done such work to an N20 in an E89.

Injecting Meth into the charger - I thought would be pushing the car beyond its capabilities.

So when I was at the rolling road, I was disusing with the engineers - and said that the WRX guys user water spray and spray onto the inter-cooler to reduce heat soak.

So I started the venture of of implementing an independent water spray kit.

Cage for water


Water Jets


Water Tanks



Primary Switch in glove box


Operator Switch

Well weather need to improve but I post testing

The plan is to use meth or screen wash with atlest 30% ethanol as this has a lower evaporation level than water - so it is able to disburse heat better than water on its own

damn dude, you went overkill. lol
A larger FMIC will have the same if not better results. the N20 isnt magic, a larger FMIC will reduce IATs in any turbo vehicle. Its proven. The FMIC i posted is 900$ US so 600 pounds and you dont have to hack up your car.....

Also, meth injection isnt going to "push the car beyond its capabilities" as long as you dont use the meth as an octane supplement you are fine. you can just use meth as a cooling method...basically exactly what you are doing with your IC sprayer. but aftermarket chargepipes come with bungs for meth injection, so need to hack your car up.

lol! I give OP credit but I cant imagine why you wouldn't just go with a bigger FMIC

Well I have an issue that heat soak is not reducing - when stationary!!!!



The 28i when it comes to mods is pants

There is only one company who makes an charge pipe for the N20 28i http://www.spacegear.com.tw/

And not found an intercooler for the 28i - have to be an guniee pig and try an wagner evo - and see what happens.

Basicall very limited options..... So anyoying and Sunday I have my drag strip day as well.....

i originally had the wagner evo 1 on my car before my current FMIC setup.
It fit fine. That was on a N54 though, not sure about the N20 fitment obviously.

hello mate,

I'm having the same heat issue on my N20 z4
Did you solve it with intercooler upgrade?

What have you done on your step 2? Just remap and downpipe?

No solution, came to the conclusion it was not big enough issue to cause me invest into an intercooler and the pain of been unknown.

Trying out a new idea - of using 135A spray - that reduces temperature to -50c and is not flammable.

No results on how effective this is yet.
