Had to make a quick 320 km trip today to a city and back, so I decided to take the truck as it rarely sees the highway, it spends most of it's traveling time on smaller highways (biways) with posted limits of 80km\hr, verses 110km\hr.With the tach showing 2600 at 110km\hr, it buzzed along like this for 1¢ hours until I got there, then the same back. Even before I got there it was working better, smoking less and requiring less fuel for the hills. It was good for the old thing. I guess I must lug this truck too much. I do drive it easy, and it needs more trips like this one. It was holding it's speed better on the hills afterwards. I've thought about putting a turbo on this, but I see the Isuzu manifold has 4 studs to hold the turbo on, whereas my turbo here has three. So mounting the turbo isn't going to be as easy as I had hoped. Oh well. It's not as important to me right now anyway. Too many other things to do, it seems. <img src="/forums/images/graemlins/pfft.gif" alt="" />

Sorry for a slow response to your Mercedes questions, but I really can't give you too many answers. HP figures should be easily has from the internet, and I find the noise to be not bad with them, cetainly no louder than my little C223. They too are good for a billion miles when looked after. <img src="/forums/images/graemlins/smile.gif" alt="" />
