I've never quite got my head around the pressure/ volume thing and may be about to look a bit stupid but......if the area being filled (pipework, intercooler etc) is the same size and the pressure is the same with any two given turbos say, K14 and TD04, then I'd have thought the volume would be the same?
I know the TD04 would be producing more power but I always though this was because the air would be much cooler as the turbo wouldn't be spinning so fast to generate the same volume. Is it that the increase in temperature with a small turbo is causing a smaller volume of air to expand which is causing the pressure to be the same?
Is this on the right lines or have I missed something obvious? I was thinking that a small turbo (T2) with a really good twin pass intercooler would be the best solution for me as it would give minimal lag but sensible power up to the point that the turbo becomes a restriction in the exhaust.
I'm not looking for power levels where I'm approaching the breaking point of components (other than cheap, standard turbos!) but am now wondering if a bigger turbo running at lower psi would be a better solution or if it would be too laggy. While I'm going over potentially old ground anyway is it worth changing from a K14 to a T2 or is there no noticeable difference?
