Im also getting a go in his full torque stage 2 when he gets it back up and running, then hes going to get the r70 pump, 1800 bar pressure thing and eventually a GT20, would be pretty rapid with a GT20 strapped on!
They certainly are!

sure if the turbo was bigger and flowing much ore air, then hell yeah make the intercooler and pipework bigger, bit its not...
I'm not talking about upping the bore of the whole system, just saying that port size on an intercooler gives a good indication of it's potential for flow, hence power. The 110HDi intercooler is designed for 110bhp of air flow, we are aiming for 160; it seems optimistic to me to try and use that intercooler. Besides, when you reduce gas velocity you increase pressure, which is actually beneficial (to a point) pre-intercooler, just look at oem systems for examples. I can't remember the exact measurements for the "C5" lower pipe, but it increases in diameter from ~43mm to ~61mm iirc - that's coming directly from the turbo and is designed to do exactly that on a turbo that's barely any bigger than ours.
I see your point tbf, but i'm not talking about installing 3" pipes everywhere, in fact if someone had suggested as much i'd be saying the same as you.
