Title: 2. turbo thru a 3. intercooler back to 2.5 Post by: carbite on September 09, 2016, 04:37:58 am turbo is 2. out. then to a 3. water/air intercooler. then to 2.5.
whats the positives and negatives of doing this?

Loss of airspeed.

The cu-ft in and out remains the same. The turbulence from such transitions is what will cause a little resistance. However, the reduction in airspeed when the flow gets into the "huge" box which is called the intercooler, will be much, much bigger and that causes hardly any problem either. So, as long as these changes in cross-sections are not smaller then the 2" out of the turbo (in this example), its not a problem at all.
The only thing that you might feel, is that bigger tube sizes after the compressor will increase 'plenum'-volume, which could increse turbo-lag/response a little. No biggie usually in my experience. |
