I feel like someone must have looked but I know with our supercharged minis that heat is a big issue for constant performance. I have an 06 R53 with 16% pulley.

So my proposal, why can't I take off the shroud for the IC and in that space between the IC and hood scoop and fit a constantly running high speed slim fan to blow through the IC? At a stopped light it would cool the IC way way down to prevent it from heating up too much under hard use. It would be always running.

This seems pretty doable.... Two smaller slim fans or one larger slim one. whatever would fit. Even slim sealed PC fans would work...

Someone tell me why I couldn't or shouldn't. It makes too much sense. Yes it would make a little noise but not much and really keep temps way down especially in stop and go traffic and hot days pushing it hard.

 

I was wondering the same exact thing ! Slightly confused that your r56 is supercharged or is it
a r53 ? I have a flat 8" diameter 12v fan I was wondering if it would fit , I have some seat foam that I can put in above the IC and check for squish. Has anyone else tried this ?

 

R53 supercharged. 2006 year

The only thing I see people saying is that it won't fit above the IC blowing down and that other people say unless the fan blows fast enough that it would hurt while in motion more than help.

 

If it was efficent im sure it would have been looked into, basically would be like one of the plug and play intake turbos.. they cause more restriction as they wouldnt spin fast enough... although im sure it would be helpful at a stop - i could see problems about 30mph or so.

 

Here we go again....
Somebody will try 10 computer fans....lol....

 

It's been contemplated, considered and tried, you're not the first to think about it.
Then the reality of the physics kicks in and you realise it will actually end up doing more harm than good.
Basically as stated above, you would only increase air flow at very low speed or idle, when it's really not very important, at higher speeds a good sealed scoop will flow far more are than a fan will, plus once you've mounted a fan or fans they will actually be in the way and restrict the higher speed air flow. Plus anything too large or that didn't fit "perfectly" would be a real PITA to configure a way to keep your hood seal, which is all important for concentrated "fresh" air flow.

 

youd be better off setting up a couple nozzles to spray distilled water onto it. like an external water/meth but with just water.

 

Is there any opinions on using a 180° thermostat
to lower under hood and engine temps ?

 

It has been available for many years. It never became popular because benefits are negligible.

https://www.google.com/search?q=mini...180+thermostat

 

M7 made them...was just a regular thermostat Thst a notch was cut so it would fit into the mini housing...imo not gonna help you...you may throw a code occasionally due to the engine not being warm...and tolerances on a gas motor are DESIGNED for a narrow range to minimize wear and maximize mpg....

 

I know at one time I ordered a 160 degree for my r53..But its not common at all.. But it did run cooler though.. never had any trouble with it anyways..

 

Ive been considering this for some time. But have stopped only because I think it would be better to just install a water mist system to cool down the IC during long waits or city driving where it is stop and go. I think this would cut down on heat soak better then a fan that isn't going to be large enough to move the air needed to keep temps down.

Toyota and some other car companies did use a fan that would turn on after the engine was shut off to cool down the carburetor and the exhaust system. There was a resister that would shut the system off when it reached a certain temp.

Ive also thought about using a fan to help cool the case of the SC enough to keep it some what cool with hopes to cut down on SC heat when running the mini hard. And then running a duct from the front of the car to blow air directly onto it when on the highway or track.

As for the fans Ive some chosen but they are not silent type fans. lol
Many or just bilge fans used on boats.

 

Just install a water/meth injection system and be done with it.

 

i have wmi, amd i love it. only thing is, it usually needs to be installed post ic.

im not an expert in that area, but im under the impression that injecting pre ic, would cause incorrect atomisation of the fluid.

i think what hes looking to do, is keep the ic itself cooler, mainly during idle, which wmi could not do unless installed pre ic, and manually controlled rather than boost controlled.

i like the idea of misting directly onto the ic, but have no idea how to set that up with out running a seperate tank, lines, and pump, at which point youd have to ask, is it cost effective?

im curious to find out more.

 

Not too familiar with W/M/I but I would have to think you would want that atomization post IC, but it may also be good post Ic for one reason ( cooler / denser charge ) and pre IC to help keep temps down. Maybe 2 smaller nozzles and boost controlled ?

 

Love it when folks try to reinvent the wheel from a couch....
Folks have been doing meth installs on mini's for years.....lots of pictures on installs around....

 

Yeah but that's going to happen, the IC need airflow to cool it which a fan will do but then a fan messes things up at speed.

With water spray over the IC you still need airflow which you don't have at idle to maximize cooling. With no airflow you'll get some cooling, not sure if it's worth it.

That's why I said just do water/meth injection. Tried and true and most bang for you buck. Otherwise you'll end up with something that doesn't work.

With your system what are your intake temps? Are they below ambient?

Zippy nh we're looking for your insight and not your comments and cerekov we haven't mentioned fans in
A few posts.

 

im just saying:

yes, i did my own wmi install on my r53.

yes, it is incredibly useful in a cost/benefit sense.

yes, it does lower my iat's, post ic.

no, it does not contribute to lessening the heatsoak of the ic itself, since it is mounted post ic, as it should be. so only the air coming out of the ic is affected.

if i am understanding correctly, what we are trying to discover, is if there are any options to cool pre ic air, or the ic itself, whether while moving, or at idle, that is sensible when considering cost/benefit.

if i mistunderstood the op, i suppose my input is done here and just go buy a wmi kit. lol.

 

Yes, you understood correctly, we were just trying to be creative, ( there still people trying to reinvent the Wheel ) . Lol.

 

Folks have tried different, heavier mass intercoolers....
They resist heat soak longer....but take longer to recover once hot...
So far you basicly have 2 options....
Simple is get a gp cooler... Same design as oem, but an extra 2 rows.....so fast recovery, no meth to buy, and it fits....meth DOES have pluses....not debating that....as does spraying the ic with something to cool it...(one option is co2), but again... Reccurent cost...water is cheap...but overtime, drips down and can corrode the injectors (will eventually happen in rain, etc) but dripping water down through it will accelerate.... And no airflow means limited evopration (when stopped)...many folks did remove the rear wiper...the reroute the sprayer (has a seperate tank on most mini's...one left/one right) to spray The ic....alta even sold a diverter st one point that had this built in...just be sure to use washer fluid in the winter or drain and flush the lines...bigger scoop just like the gp cooler helps when moving...butblittle can help stopped...moving the ic was tried...piping is just too long...makes lag...
Other option...water to air intercooler....kinda rare... And can do worse in some cases...again drawbacks...costs....sure engineers calculated whst was best for most...and in many areas...it works...gp is the oem...just a BIT better....
Meth....imo evidence of it kills resale...some care...some don't...
With a custom tune...maybe 2 maps...one meth, one non....you can have great fun...meth cools and adds octane.... Gen2 guys love it cause it cleans the intake too...
But when it goes wrong...not as bad as nitrous....but can still grenade a motor if a nozel clogs or you are tuned for it...and it stops Or floods the motor...so not for me...lacks the safety ...
Fans imo are a no go...if you think keeping a ps cooling fan alive is hard...wonder how bad a fan(s) on the top would be....also nothing is free...extra electric load= lost hp to parasites like the alternator...
And besides....
A MINI is about HANDLING....
NOT 0-60 TIMES....
You will never run many drag races in a mini...it is as aerodynamic as a brick...but win a canyon run yes....remember...build to the cars strengths....a little faster is nice...
But in 99% of the cases, more power is not the answer... 1-a better driver...driver education...and 2- better handling....
A good r50 driver can BEAT a pretty good r53 driver....with less hp...and they do have some advantages.....
Build you car to its strengths...it will be more fun than if you try to bandaid the weak stuff...lots of hp is fun...but carving turns at speeds others cannot dream of....that is the mini.

 

zippy you just sparked somethin in my brain. idk what it is yet, but it ivolves my rear wiper motor. (no longer used because of rear wiper delete)

new project time :D

 

Thanks for your info ZippyNH much appreciated ! I bought a Mini jcw in December and I'm just checking the in's and outs of the little car out, so I'm probably revisiting things that have been beat to death already, and I agree with handling thing, but more horsepower is always nice !

 

I thought I smelled something burning !!! Lol

 

get one of these so there is nothing to interfere with air flow lol
