: On the whole, satisfaction with either unit is probable.
: BEGI.....slightly more power, significatly more complex install, expensive.
: Sebring.....no intercooler, generally easier install, less expensive.
: On the whole.....I don't know. I love my Sebring "enhanced" 1.9......Karl loves his BEGI "enhanced" 1.9. I can say, looking at the graphs, you get more "bang for the buck" from the Sebring unit.....however, does that come at engine life cost due to higher temps?...I don't know! My temperature gauge hasn't moved, pre/post install though.
: My advise...think long and hard.....if you are willing to modify the engine, then talk to both sides...I can give you a number/person at Downing Atlanta and Karl will give you the BEGI info as well.......basically, it's more of a philosopical choice.

I thought the "engine life issue" had more to do with the force of 7.5+ PSI blasting through the valves into the combustion chamber affecting the pistons/rods, etc (according to my BMW parts manager and others on this board). I don't think temp is as much an issue with a Supercharger as it is with a Turbocharger. One of the things I like about the Sebring unit is the "bypass" function that reroutes air back into the blower when you're not asking for boost via the throttle - it would seem that this would help provide relief for the engine, depending of course, on your driving style, and how often the right foot is buried in the fuel injectors. I'd think that someone who drove fairly rationally (but who liked having the power "on tap") wouldn't harm the engine significantly. I've no idea if BEGI has a similar feature - I've never been able to get to their website.
