Most cost effective HP+ modifications?

[Mrmaddbrad]

I'll say it again... A car with 200hp that weighs 3000lbs is a lot slower than a car with 200hp that weighs 2500lbs.... Like WAY slower...

Granted, unless you totally strip your car you're not going to get 500lbs out. But even 100lbs is feelable... Just take stuff out of your car! It will be faster..
And thats like $0 per hp lol. Cuz you're not gaining any horspepower or spending any money!! lol

If you want a car in a fast line, boxsters are not the car for you. If you want a great handling, fun, gorgeous car, then you should buy a boxster... Enough said.

True weight make a big difference. I think I read somehwere 0.2-0.3 second 0-60 improvement for every 100lbs lost. Problem with lowering weight-I drove without the engine cover carpet. I removed the carpet on top and the carpet behind the lower driver/passenger seat.

The car sounded horrible. It did not sound sporty at all. Those 5-10lb carpets make a huge difference in how good the engine sounds.

I thought of replacing front spare tire with Fix-a-flat spray, but idk how it effects my rim when trying to get a new tire? Has anyone used fix-a-flat? And I believe there are only 2 or 3 aftermarket rims for this car that are actually lighter than stock rims unfortunately.

All too true re taking the carpets out. Just makes the car sound rough as hell, doesn't it?

I drove round in the stripped out track-prepped BMW for three years. No spares, no gunk, just winged it.

Actually, I've never had a flat...

Haha well then take the weight from some where else :P Also, fix-a-flat is supposed to work if you also carry a bike pump and tire pressure gauge with you. The tire will still be flat after you fix the hole unless you reinflate it... But in reality, just get insurance that provides "free" towing. Tow it back to your house, take the tire to be fixed in another vehicle, call it good.

Flats are so rare, that i don't think the 20lb spare tire is worth it..... I've never had one, just avoid pot holes....

But the carrera 5 spoke wheels weigh A LOT less than the turbo twists that come with most boxsters...

The oversight here is when one is travelling and isn't anywhere near home, which we have a few members on here who do, and is usually when life decides it's time for you to experience a flat tire. Jäger just recently went on a road trip over the summer that he shared with us on here, and he experienced a rear flat on the craptastic highways of OK not even halfway through his round-trip journey. And he had that car packed to the gills, but he didn't leave home without that spare.

One of those reasons why I don't beat myself up too much about not going with a 987...I still have a spare.

If you're traveling why do you need weight reduction? Are we not talking about spirited driving/racing here? I mean why else would you need extra hp? For cruising down the highway? Its not like it takes 5 hours to put your spare tire in... Just put it back in when you're going to travel, if you're around town, take it out....

Stop being so irrational.... Or don't take my advice, and turbo/supercharge your car and wait for it to blow up...

Where does a flat rear wheel go if you take it off?

Guess it is the GF or wheel??

Just lean it back in the frunk. It fits fine. I always carry a full sized spare there on track days.

First, chill. Second, I'm not the one asking about turbo and supercharging my car, so ease up there, too. I was not saying you're wrong, I said there was an oversight in what you said. I may not work in an auto shop, but that doesn't mean you know everything there is to know already, either, so don't take everything said in response to you as a personal shot.

I was referring to this more than anything else from your previous statemt:

You don't think the 20lb spare is worth it, you've never had one, and your advice is just to avoid potholes? So unless I'm reading your statement wrong, you're saying you don't believe in having a spare because you can avoid all dangers to your tires, and you get the performance advantage of 20lb less in the car. And I'm being irrational? A flat tire can happen anywhere and for many reasons, and I'm sure you've seen them all, from running over nails or glass, to potholes, to who knows what the heck you ran over that sliced your tire apart. I've seen a golf ball-sized rock somehow embed itself in the sidewall of a co-worker's tire and break the bead, so when he came out of work he found his vehicle sitting on a rear flat with a rock jutting out of his tire. He has a 65 mile commute...make sense to have a spare then?

I've picked up nails several times, thankfully none with the Porsche, yet. Yes, it's a very infrequent occurence considering how long I've been driving, so I won't disagree with you there. All the nails my tires have picked up have been local, within 10 miles of home, and even in my own driveway. It just happens, and it sucks every time because there's a chance it compromised the tire. I've just been lucky that only 2 required a patching of the tire. And if my tire did go flat, I'd much rather take less time jacking my car up and throwing on a spare to get home on my own power than wait around for AAA or some other "free" roadside service. To me that's just invonvenient when I have it right there in front of me to DIY.

For tracking and any other racing, you are 100% correct, and I'm not disputing that every pound lost will count there. But you didn't stop there. You also said toss the spare out when you're around town. How much of an advantage is your local spirited driving experience really going to see without the spare tire in front? As you said, we're talking around town, right? How usable is that 20lb weight loss even in Sunday traffic? It might net you a thousandth or two of a second less approaching that next red light/stop sign...aka negligible. But sure, in the name of spirited driving, which just can't be had with an extra 20 lbs sitting up front, let's just say your statement's completely rational. I know that if I ever get a flat a mile from home I'll be glad I have my spare and jack ready to go.

Maybe you've got better roads where you live, but around here the roads are complete crap and only get worse as the winter comes and goes...you'd think someone mortared the streets sometimes (though we've got nothing on Boston, MA). I don't feel I need to be on a road trip to need my spare, because you never know what can happen on public roads.

If anyone has thought of getting the Autothority Turbo Kit for the Boxster, I already called and asked for pricing.

8psi on stock internals(not good for our high compression engines) and promise of 380HP after they are done with it.

$30,000 for the kit. That can't be justified. Turbo Kits on normal cars cost $1000-5000.
