There has been alot of talk about ICs lately. I was reading on another website that said having two ICs can reduce the intake temp like 30-40 degrees. Anyone ever thought of this? maybe leaving the stock IC on top, and then plumbing another stock IC or starion or volvo or whatever in also?

Here is a link to some IC info:

You could potentially lose alot of pressure doing this, theoretically it sounds good though

 

I think someone with access to a dyno should do a test on all these questions. Unless we have exact numbers its just opinion about the starion/supra/volvo ICs.

 

While I'm not an expert on this subject, I believe this topic is similar to how a newbie would believe that twin turbos would make more power than a single turbo.

We all know that this depends on the circumstances.

If you read the link, there is mention that the Volvo intercooler is a single row unit. In that sense, the Volvo would probably benefit w/ a second intercooler (assuming that there was room to install it). However, that same cooling benefit could be obtained from a single (dual or triple row) intercooler.

Without getting too involved w/ intercooler sizing, the answer to your question would be: YES, a car can benefit from a 2nd intercooler BUT there are circumstances in which a single LARGER intercooler would be just as beneficial.

 

I know what you mean, but maybe this would be a cheap alternative to spending 1000 on a new FMIC.

 

Well, if you want to go for a cheaper route, I would consider getting a larger intercooler rather than dual. The reason being is the space/clearance issues that you may run into. It would be easier for you if you only had to run piping to one intercooler as opposed to running two different sets of piping for two intercoolers.

Not only that, but assuming that you were on a really tight budget, you could get a core from a diesel truck for example. From there, you can cut the core down to size and fabricate the end tanks/piping.

That in my opinion would be more economical. It'll be less stress for you (in terms of the fabrication required). Personally, I would just save the money to purchase a FMIC, but this is a cheaper alternative.

 

If the Volvo/Starion IC's worked as well as a Spearco core or a Greddy core, they wouldn't be so cheap. The new Greddy kit at just about $900 shipped is CHEAP. If you are gonna go through the trouble of making pipes ect yourself at least make it worth the trouble and get a real spearco core.

I believe the Mazda Millenia S that is powered by a Miller cycle engine and a Lysholm supercharger set-up comes w/ 2 ICs from the factory. One for each bank of the V-6?

A supercharger probably has less problems w/ pressure drop and boost response drop from too much volume and restriction in the IC compared to a turbo - and with the high boost the Millenia S has from the factory they needed the cooling area.

With twin turbos or twin charged using an SC and a turbo I think there are instances where 2 ICs would simplify the IC piping and possibly provide less restriction, but for single turbo I can't think of why dual ICs would be better.

 

Putting two stock TII ICs in series would result in about a 3.5 PSI pressure drop. Way too much...

A bigger intercooler is the way to go.

 

Yes, series is bad news. If they were routed in parallel they would work much better.
