I've noticed for a while now that some companies seem to be coming up with budget single turbo kits which make use of the stock exhaust manifold.
Are these really such a good idea or a false economy ? Or is it just a current 'phase' that so many people want to go to a single turbo, that they'd rather go single than think about the overal solution and hence these companies are just supplying to the demand.
We all know how restrictive the exhaust manifold can be at high hp levels and it seems that to make use of it to try and drive a single is going to be quite challenging. I have no doubt the turbo's people are talking about can make some good numbers between 500 & 600BHP, but how well do they spool ?
Using the stock manifold that is designed to spool two small turbos to now try and spool a bigger turbo just doesn't seem too logical to me and hence possibly false economy.
To try and put it in practical terms i could quite well imagine a stock twin BPU car getting the jump on one of these budget single cars until they have spooled, which in turn would make the day to day driving of a budget single solution........interesting.
Anybody have experience of these budget single kits? (i'm talking manifold adapter type here, not the kits that come with a complete replacement manifold)
