charge cooling ...methanol injection
Turbo Mini Forums

well boys thought id chuck up a post to see what kind of information pops up.
been looking through some old mags ( i have millions) and just wondered if anyone is running a chargecooler, and why more of you arent..ive heard some very good results can be had from a decent charge cooler set up, ive seen a couple turbo minis running them, among alot of other cars...is it more of a space restriction than anything ? as my thinking would be a charge cooler could offer a much cooler intake temps
also after seeing rich' s water injection set up at the RR day and also speaking to a good mate of mine recently about methonal injection, as a friend of ours runs it on his 300bhp ibiza, was just wondering if there are many of you running meth injection and if not if there are any reason why not...

just general brain over flow really :)

I'm surprised more arent using it too, and a chargecooler should offer better cooling by design. Albeit more complicated packaging. But there would be more freedom with size of the cooler.

Very interesting thread though on pre-compressor injection.

The big downside to a chargecooler is that if the water leaks or the pump fails you have lost your cooling. An intercooler normally has no moving parts to fail.

i think it could really interesting to see what kinda of difference in intake temps from a commonly used mini intercooler (cossie 2wd) and charge cooler system...could even monitor the water temps for the cooler to ensure higher boost cars are within certain perameters to avoid det ??

i was always told that a charge cooler is better for short sprints IE 1/4s ect and an intercooler is better for higher speeds and long runs.

i would say that's spot on Gary, every thing at some point is a compromise.

water is better at cooling...so clearly a well designed system will always be better than one using air/air.

Otherwise all engines would be air cooled.

But a A2A is zero maintenance and if you can fit one big enough, more than up to the task.

With either setup it all boils down to sizing it properly to do the job.

I was pointing out the downside that it has the capability to leak, which is exactly the same as a cars coolant system (which aren't unknown to leak when fitted as the factory intended on any car). An intercooler can only leak air. A charge cooler system can leak air and water.

If you can't fit an intercooler, then it can help with space issues, but they cost significantly more for possibly no gain in power. Fitting a chargecooler where an intercooler can be fitted goes against the most basic of engineering principles - keep it simple!

Unfortunately, you have to cool that water with air so you are back to the downside of an intercooler.

the one thing i was thinking was with a chargecooler do you think its an easier thing to monitor with readings of the water temps cooling the charger.. knowing exactly what temp the water is and knowing the intake temps are being cooled sufficiently, must have some benefits ??
