Would it really be that beneficial? 40mm is very narrow - I've never owned an intercooled 8vT, so can't actually picture it - but it sounds a little tight. Whether making it bigger would make a difference, I'm not sure. IME restrictions like this matter a lot less on turbo engines than on NA ones. Having said that, I think if it was mine I'd be tempted to give it a try. Shouldn't be too difficult to do. -- Grunff
