I can't speak for Guy, but honestly, the car industry is always slagging each others products. If you accept any vendor's appraisal of a product that they have a directly competing product for you're an idiot, pure and simple. Remember, this is the same APR that charge $3000aud for a turbo you can buy online (legitimate borg warner unit) for ~$1000 us.
Heres the facts:
1. Plautos's car is running a GT28RS, thats a much bigger turbo. Thats a lot more air, and an intercooler designed for a K03 is likely not suitable for the following reason:
2. Air cannot be cooled unless it interacts (Via friction) with the intercooler. If there is no friction (eg, the intercooler flows HEAPS), it will not cool the air. The right intercooler is the one that provides the best trade-off in terms of restriction vs cooling ability.
3. An intercooler that doesn't result in a loss of boost is not cooling the air. The boost does not 'magically' disappear... it goes down because the air is now denser (cooler air is more dense). The same amount of air comes out as what goes in. 'Boost Loss' through an intercooler is irrelevant.
4. Its worth noting here that the MAP sensor is POST intercooler on the Polo - so any loss of boost pressure will be taken into account by the ECU; it will work the turbo harder to get the programmed boost. This will result in more overall air. I would have thought a tuner would understand that fact.
I'm not saying the forge unit is the best one - it most likely isn't as its a turnflow. But to say it results in a 'significant loss of performance' is absolutely and utterly misleading.
