I had a question for anyone not too angry and still following this thread.

Are there any good fuel efficiency mods that anyone is aware of?

Obviously the Boxster and even more, the Boxster S, are not too great at fuel Efficiency, although not all that worse than the 330i I currently drive.

Is there anything that can be done other than weight reduction to improve my street mpg?

My limited knowledge brings me to believe that higher performance = better fuel efficiency, but I could be wrong. Would something that is proven to give hp gains like an Underdrive Pulley help with fuel efficiency?

I can start a different thread if need be.

But what are your thoughts?

IMO Performance doesn't necessarily mean better fuel efficiency. The biggest thing that effects fuel economy is driving habits. If you want fuel economy, imagine there's a raw egg between your foot and the gas pedal. Press down gently as not to break it. Using your brakes is wasting fuel. Look far enough ahead so you can coast to your stops and use the brakes as little as possible. Shift points make a difference too.

Now, if you want to race, that's a different story altogether.

Thread high jacking . . .

Here is the view from my dining room this morning. My drive way is between the 2 poles just to the right. It has warmed up to a balmy -25 C (-13 F) with the windchill from a flash freezing -40 C (also -40 F) from a day or two ago. Obviously NOT Boxster weather. Time to fire up the snow blower (which i also maintain myself LOL)

The base Boxster with a manual transmission is not an economy car, but the fuel efficiency is pretty good. I have taken long highway trips during which I averaged about 30 mpg. The car can run on regular, but you should use premium fuel and that adds to your fuel cost. If you drive in congested areas, fuel economy takes a hit and you will be fortunate to average 24 mpg. If you "drive it like you stole it" fuel economy will be even lower.

Around $4k or so later I had the car in shape and with a maintenance history I felt comfortable with and only then would I drive it anywhere.



Tires, brakes, alignment, 90k service. Nothing exotic or wildly proactive. Not even anything inside the engine or an IMS swap. Nothing cosmetic. And those were 10 year ago prices.



Wonderful cars if well maintained. Buy one whose maintenance history you can prove. Whose reason for being sold you can trust.

Thank you both, great input.

A underdrive pulley will help, rebuilding the engine will help.

I think the 6-speed manual trans helps Highway mileage. After rebuilding my 'S' engine I easily get 30 MPG at highway cruising speeds (70-75 mph)

The 6 speed swap was said to be pretty hard. Might have to avoid that

Thanks for confirming the UDP. Sounds like that and weight reduction is the key!

Hey buddy! I’ve been trying to be more active (outdoor activities) and stay off the internet. I don’t check in daily, anymore.
Glad to see you back around here!

Takes a big man, nicecar.

Glad you're sticking around. I think everyone's input is valuable here, even PW's, even if one's input contradicts another's. It just gives the reader/OP more information to go on and make their own decision.

My new favorite member. (at least for the rest of today, haha)

It takes alot to say "whoa nelly.... I might've (whatever... I won't belabor, you all know what I'm saying here)"

and funny thing; I don't even remember the episode you're referring to here. If I was rude then, my apologies now. I'd love to tell ya I'm just misunderstood, and that it was surely just me trying to be funny / sarcastic. But the truth is; I'm sometimes a dick. (that's why I always try to forgive other people who are sometimes too. hahaha.) If I were never going to say anything wrong or offensive, I'd need to change my name to Trump.
