Supercharging the V8 Engine

[Bunglist]

I have seen the company that are doing this modification for the chimaera and it looks quite interesting, however I was talking to a couple of chaps the other day about this, and these chaps know the Rover V8 engine very well, and they both reckoned that if you supercharge the engine and the engine is in good working order, it will shag it very quickly, but if the engine is shagged already then the supercharger will not damage the engine much further apart from general wear and tear.

The reason i was given was that a good engine will not be able to take the pressure and will shag up very quickly, however a worn / slightly shagged engine will release the pressure easier due to the many parts already being worn and not fitting as tightly as if in good condition.

As i am not techy about this sort of thing and wondered if anyone could shed some light?

That wouldn't really be my opinion unless it's an early engine with slotted pistons etc. Even so it should still be able to handle 5 psi so I'd be happy to use 5 psi on a good engine. As for a shagged engine, may as well try it as there's not much to lose anyway.

Plus I would have thought TVR Power, who used to be owned by TVR a few moons or so ago really ought to know what they're doing,and wouldn't suggest such an option if it were likely to end up with bits of customers cars spread all over their doorstep?

That sounds very strange and I'm curious to know why they thought that. The only reason I can think of is that a completely knackered engine could be so far down on compression that you can simply bung a blower on and get away with stock fuel and ignition without any detonation issues. I don't think I'd want anyone working on my car who took that line of thought though. Perhaps there's some more subtle reason?

Sounds like a load of old codswallop!
