There is an advantage using two systems, maintaining the water pressure and not tailing off at high duty cycles of the HSV - the system can be made very linear to the VE curve.

I wanted to do something to improve performance, i was thinking about a stainless steel exhaust with sport cat - might yield 15 bhp if i was lucky, at a cost of ?1000. Some one else would have fitted it, job done.
With WI, theres a lot more involvement, with the potential to make some serious power gains.
Thats not to say i wont be replacing the exhaust anytime soon, what with improved performance, got to get the extra gases out :smile:
That poses a question, with lower in cylinder and exhaust temps, are the exhaust gases therefore denser and back pressure reduced ?
