SMIC options

Recommended Posts

Currently considering changing my stock intercooler for another cooler in the stock position. I dont fancy an FMIC due to hearing about issues with overheating and causing your air-con to fail, plus you have to declare it to your insurance. I know the stock intercooler is actually quite capable when in good condition so this is why im thinking of getting either another standard cooler in good nick or an aftermarket cooler to go in the stock position.

So what are my options? I dont really fancy paying nearly 1k for a SMIC so does anyone know of my SMIC options with a budget of 500 squid and under?

As you probably already know Chris Wilson sells a very good SMIC alot cheaper than Mr 'T'. I'm pretty sure that Liam does one too.

 

If your after silly cheap you can always try the link below to one that Nic is selling, I don't know enough about SMIC's to tell how good a second hand one is, so for piece of mind I'm going to have a CW one very soon.

Hope all that helps mate, but I'm sure someone who knows what there talking about will be along soon ;)

Alternatively you could DIY a chargecooler. Preferable to a FMIC IMO.

You could fit a water rad right where the SMIC sits, utilising the existing front & rear ducting.

Pace do big-volume heat exchangers, and pumps are cheap. Space will not be an issue, no extra heat in the bay, no degradation of aircon or coolant rad, and a tank filled with ice will bring charge temps below ambient for 1/4 mile sprints.

Pressure drop can be lower than any FMIC or even SMIC.

 

Main downside will be heatsoak during trackdays (circuit), after a few hard laps it will need time to rest and get rid of the extra heat.

Fox, you are asking the wrong (impossible) question. If you fit a single turbo that runs efficiently at an airflow capable of supporting, say, 500 BHP, the intercooling needs will be *LESS* than trying to run the stock turbos to support 350 BHP. All I can say is that my IC has less pressure drop and more efficient charge cooling at a similar internal and external air flow rate than a new stock one, by a fair margin. I won't uote figures, i refused to fund proper certified testing as it would have been silly expensive, but i have now blagged a couple of air flow modelling sessions FOC, as i am using the same company to do a couple of expensive race rads and some other stuff, so they were in a helpful mood.
