meier motor sports Posted September 10, 2007 Share Posted September 10, 2007 The AEM & CBE with custom TDC tune would obviously win and you know it. but but...... i like pie Link to comment Share on other sites More sharing options...
Earthworm Posted September 10, 2007 Share Posted September 10, 2007 That doesn't negate the fact that an aftermarket is better if done right. Yes I think it makes sense that a properly tuned OEM intake and a properly tuned AEM CAI ran under identical conditions would reveal the aftermarket CAI would make more power.

Vimy101 Posted September 10, 2007 Share Posted September 10, 2007 ^ What leads you to believe that the OEM system is improperly tuned? A tune for a specific narrow ambient temperature range might produce a few more crank hp in those conditions but lose a few hp in others. Link to comment Share on other sites More sharing options...

whobaru Posted September 10, 2007 Share Posted September 10, 2007 Doing it right would require a tune. That's fine, but probably what would happen is that performance would be lost in other running conditions. The TDC (?) post remarked on this. It's all about compromise such as getting decent performance and relaibility from -40C to +40C. The OEM tune is quite remarkable in that regard IHMO. Are you saying the custom TDC tune I just ordered is good only for a smaller window of temperature than the stocker? Link to comment Share on other sites More sharing options...
Vimy101 Posted September 10, 2007 Share Posted September 10, 2007 Are you saying the custom TDC tune I just ordered is good only for a smaller window of temperature than the stocker? Most likely. Tunes all involve some amount of compromise somewhere. Serious race tuners set cars up for temperature ranges of just a few degrees for a given race day. The OEM intake and tune is for a wide range of conditions. If, let's say, you live in a warm climate and tune the car for your prevalent conditions taking the car into a cooler climate will probably result in some loss of performance in those prevailing conditions. Put it this way, if all Subaru had to do was to stick an AEM intake on their cars to get instant better performance instead of designing and engineering their own, they would do it. They don't though, however, because there isn't much to be gained overall and probably more to lose from a reliability and warranty standpoint.

meier motor sports Posted September 10, 2007 Share Posted September 10, 2007 oem take more into consideration then performance. cost, servicability, how it can handel adverse conditions, and fuel milage Link to comment Share on other sites More sharing options...

Vimy101 Posted September 10, 2007 Share Posted September 10, 2007 oem take more into consideration then performance. cost, servicability, how it can handel adverse conditions, and fuel milage The hp gains to be had from AEM intakes even with proper tunes are minimal at the expense overall functionality and other things such as those you listed. The OEM system would be fine until really big hp mods are made and only then because much more air would be needed. Link to comment Share on other sites More sharing options...

Richard B. Posted September 11, 2007 Share Posted September 11, 2007 how "bad" is the stock setup? do aftermarket systems filter as much as stock? they obviously flow more air to make it worth while but at what expense? Link to comment Share on other sites More sharing options...
meier motor sports Posted September 11, 2007 Share Posted September 11, 2007 stock is fine. Link to comment Share on other sites More sharing options...
Richard B. Posted September 11, 2007 Share Posted September 11, 2007 stock is fine. that's what i am trying to get at. IF it is proven that the aftermarket actually filters as good or better while flowing more air, then yeah, improvement can be had. if not, then it is a give and take and one can't knock the stock system for trying to filter more dirt than flowing max air.

meier motor sports Posted September 11, 2007 Share Posted September 11, 2007 i have the stock box's and an aftermarket filter. couldnt tell you what flows more. or i probably could devise a way but i dont really care Link to comment Share on other sites More sharing options...
whobaru Posted September 11, 2007 Share Posted September 11, 2007 The point of an aftermarket filter is to filter the same amount of particulates, but just not suffocate for the purpose of muffling the sound. If I had to guess, I'd say the stock filter does catch a little bit more stuff, but that IS at the expense of performance. Link to comment Share on other sites More sharing options...
Vimy101 Posted September 11, 2007 Share Posted September 11, 2007 ^ The OEM system is very efficient. AEM's are a waste of money unless you're running really big power mods. As I mentioned previously, Subaru engineers aren't going to leave easy gains sitting on the workbench. Link to comment Share on other sites More sharing options...
