trinitom Posted June 2, 2009 Share Posted June 2, 2009 I have a CBR fan (motorbike) it’s about the same size of the stock intercooler. do you guys think it’s a good idea fitting this behind the intercooler for those very hot days, or spirited driving?

dr_jekyll Posted June 2, 2009 Share Posted June 2, 2009 extra cooling is allways a good idea IMO Quote Link to comment Share on other sites More sharing options...
JustGav Posted June 2, 2009 Share Posted June 2, 2009 I would hazard a guess that when stationary it would help avoid the heat soak and the intercooler warming up, but when you are moving the fan mech and surround may act as a hindrance for the airflow.

Tricky-Ricky Posted June 2, 2009 Share Posted June 2, 2009 If you really want to improve charge cooling just fit water injection. Quote Link to comment Share on other sites More sharing options...
trinitom Posted June 2, 2009 Author Share Posted June 2, 2009 If you really want to improve charge cooling just fit water injection. And how much we are talking for one setup like this one??! Quote Link to comment Share on other sites More sharing options...
_Shane_ Posted June 2, 2009 Share Posted June 2, 2009 I have the aquamist kit in my car now a few years and i think it cost about 350-400 euros for the kit and fitting Quote Link to comment Share on other sites More sharing options...
trinitom Posted June 2, 2009 Author Share Posted June 2, 2009 my fan only cost £20, and for bpu level i think there is no need for aquamist route. Quote Link to comment Share on other sites More sharing options...
Wez Posted June 2, 2009 Share Posted June 2, 2009 The stock SMIC ducting does a very good job directing air through the IC when moving, I wouldnt bother with a fan, as already mentioned it would only help when sat in traffic and prob cause a restriction when motoring. As for WI on a BPU, I would say its a good idea as the little stock tubbies when pushed outside there effeciency will generate more heat than a single setup running in its effeciency island Quote Link to comment Share on other sites More sharing options...
Homer Posted June 2, 2009 Share Posted June 2, 2009 Look at it this way - when under high boost and load (load being the key factor) you're going to be doing 60+mph. If the fan can shift air through it at 60mph while stationary it will match the flow at a genuine 60mph, but once the car reaches that speed it will become a restriction (lowering efficiency below that of a system without a fan) and cause higher load on the electrical system. The stock system is fine for all but the most power hungry single/big twin systems PS: Above is just an example, in reality the fan pushes air through at much lower rates than 60mph Quote Link to comment Share on other sites More sharing options...

You are missing the point here.... The fan surround and motor will ADD a restriction and less air will flow through the IC.... The only thing you will do is cool it when you aren't moving but when you are you will cause it to get hotter. The IC will flow less air during idling anyway, and will need the airflow when on boost. You are far better off wiring in a small water pump and spraying water on the IC through a spray bar. Quote Link to comment Share on other sites More sharing options...
