I'd recon that if the 4 litre is producing 338BHP and 427LBS then the 5 litre must be producing north of 500BHP and 600LBS surely .................

Don't know for sure but usually they are stepped aren't they to smooth out lag?
Also, I wonder if the increased surface area of two and their piping helps dissapate heat more or actually creates more?
Maybe where you have twin manifolds it makes more sense and is more efficient to run a turbo on each as opposed to a single one at the collector?
No idea really.

Advantage - turbos can be smaller as they only have to deal with the flow of one cylinder bank. Smaller = more responsive, reach max boost sooner
Disadvantage - packaging, weight, more pipework & surface area = higher thermal losses
And dont forget cost Disadvantage - packaging, weight, more pipework & surface area = higher thermal losses
I would have thought the single turbo kits are all you need, and lets not forget affordability is a big factor here.
Given the value of our cars, £2.5k (plus engine management changes if needed) puts it in the "affordable" bracket for anyone with forced induction aspirations.
For example, by my calculations Eann Whalley's turbo kit is going to work out about half the cost of an SC-Power supercharger kit, it should easily deliver the same gains and probably has the capacity to do a lot more.
Before the turbo kits came out I had dreamt of an SC-Power kit, but deep down I knew I would never buy it on the grounds of cost.
Lets face it, we all know this engine has breathing problems, so I had planned to throw £800 at my heads for probably what amounts to a a 30hp gain, then call it a day.
But now with the advent of affordable forced induction it makes sense for me to forget the heads & put that money towards a turbo kit that should easily lift the output by 70 - 100hp.
I'll still have my standard heads, but does that really matter when I'll be force feeding my engine at 8-10 psi ?
Obviously the turbo kit is more money up front over doing something with the heads, & interestingly they do offer the same return percentage per £pound assuming you have already have the engine management system to cope with forced induction.
But adding 100hp is a very different thing to adding 30hp.
I see 30hp as a nice tweak that I'll get used to pretty quickly, 100hp on the other hand is game changing.
A turbo charged Chimaera is going to be a completely different animal & I doubt I'll get bored with it in a hurry.
The way I see it, sometimes it's better to leave the money accumulating in the piggy bank a while longer to get something significantly better.
Hats off to the developers of these kits, cost effective yet significant power gains is what the market wants.
And we just got it
