Ferrari Mailing List: Re: 308 Mods

[David (david]

There's a supercharger kit that is bolt on. You'd have to go to Fchat for
the details and dyno charts, but it is a very healthy hp increase. About
$6500 from memory. (!)

If you are handy with and have access to a machine shop, DIY supercharging
would be the best bet. There's no need to change anything in the CFI other
than to ensure it doesn't leak on the high pressure side. Apparently it's
the same system (exactly) as used on a Porsche 928. The exhaust can be
whatever you want - the freer the better, and there's no need to rebuild the
engine until you break something :) The standard 4:1 compression also likes
the forced induction.

Add in an intercooler and water injection, and up the boost to 20psi, and
find out what breaks first! I remember Ric Rainbolt doing something similar
and finding that about 400 hp was a safe upper limit before drive train
components started to get fragile.

Anyway, it sounds like a fun project. I think a sc would work out cheaper
and easier than tricking it with normal aspiration. Probably more power and
better drivability too.

Just my 2 cents.... Dave

What would you guys do to a 1980 2v injected 308 to get more normally
aspirated hp and reduce weight?

I know I could:

1. Go to Fchat
2. Install Chevy V8

But what upgrades have listmembers done to achieve some modern hp increases?

I'm thinking a set of hot cams, ported heads, 10.5 pistons and EFI would do
it.

Thoughts?
