THS Intercooler for 2.0TFSI Cars
vRS Carl:
Cheers KRL
I understand it now :happy2:
Poppa Dom:
Having clocked up some 16k miles with the THS fmic I can vouch for it being a well designed and quality engineered piece of kit.
GTIforpassion:
Very interesting thread, many thanks !! :happy2:

--- Quote from: KRL on September 03, 2010, 02:40:03 pm ---^^^ Carl, I think what T_T means is that an intercooler with a very efficient flow rate will mean the turbo will not need to boost as much to meet the specified boost.
The measurement for boost with VCDS is taken post the intercooler. So for example if you are boosting at 20 PSI the turbo may actually be boosting at 25 PSI to make that 20 PSI post the intercooler. All the stuff between the turbo and intake manifold (intercooler, pipes, tb pipe) will cause a drop in boost pressure.
Therefore if you have an intercooler with a highly efficient flow rate it will mean the turbo is not having to work as hard to meet the specified boost. For example with an uprated intercooler it may now be boosting at 23 PSI to make that 20 PSI post the intercooler.
These figures are just exmaples so not accurate to any specific intercoolers.

That's exactly what I was trying to say! :happy2:
The real test of an intercoolers 'internal' efficiency should be its internal flow rate - in American English, that would be 'cubic feet per minute' (CFM), or in metric 'litres per minute' (L/m). High CFMs are far more important than high boost pressures - but sadly, most peeps are not aware of CFMs, and get hung up on high boost readings.

I spoke to Revo and they are THS fans ahead if twintercooler. I like the idea of lower temps, improved efficiency and less soft/flat performance in the summer. Plus more headroom against det
I'd love to see figs for power improvements against the twintercooler
