Re: [doc] Re: To Turbo or not to Turbo

["Dan Willis" <danielpwillis@xxxx>]

I'd agree.

You think we could get 285Bhp out of this lump without a turbo? I doubt
it... but then, there are some very clever people out there! A newer 24
valve lump could muster at least 250Bhp without sweating though...

Also worth noting that two turbo's *could* mean more heat than one average
sized one but I'm guessing here as I've only seen setup's like Supra's being
in the front.. the A610 I drooled over for many hours was a twin setup but I
can't remember how it worked (that is, it was a good year before I owned a
D).

You do bring up a very valid point here.. intercoolers. If your
intercooler(s) is tiny and not well supplied with cool air there is no point
having a turbo setup at all. It's the biggest reason my Calibra runs out of
puff when it does... the intercooler I'm saving for is an 8.5 litre front
mounted unit... and it's £600!

Nice engine btw...
