2.7, 2006 Boxster Upgrades

[Boxmike]

Thank you for the info.
I've read and reread article after article on exhausts, flashing, K& N filters etc.
20 to 35 HP at the crank may or may not be noticable. Checking it all out after the job is done on the dyno, well what happens if it isn't as promised or the car runs like crap?
Looked at a TPC racing low pressure turbo unit, that's got to work.
But the price $7500 plus..Ow!
And how will th car run afterward?
They say it runs like a stock car..well maybe.
Very fustrating to find out there's nothing to be done...but we send people to the Moon don't we?

Thought this forum(and the others) would have some answers.
If what you say is true then it seems there's a lot of guys spending some hard earned bucks on masturbation.
Rather spend my dough on a vacation with a hot blond with big boobs.

Comments ...anyone?

Thanks to everyone for their posts.
I'm disappointed but not as much as I would be if I spent my hard earned cash on BS.

I've bought a jar to start saving my pennies in for that GT3 RSR I saw on the showroom floor today.

Figure I should have that new GT 3 by MY 2050

I suspect that by far the most cost effective performance upgrade for the 2.7 Boxster is to sell it and buy a 3.2 or a 3.4.

if hot blonds and boobs are your thing then by all means.

but yes a low pres. TPC is a good kit and being low pres. it will drive more like an NA car.

but Like I said previously if you want raw power save for an X51 motor. if all you want is straight line performance for cheap... might as well forget even that GT3RS you were eyeing because that also will lose to any moderately built muscle car for a fraction of the price in the straights.

if you want looks there are many things you can do to make your car a looker. hey maybe you will impress a big boobed blond or two.

OR you could just find some good old bendy roads and tear the **************** out of your car. because you and her will love it.

IMO, turbocharging a Boxster without changing other components, particularly the IMS bearing, is risky. Porsche didn't want it's new entry to cannibalize the 911 sales. As a result they did an excellent job of making sure a Boxster that can compete with the 911 would have nearly the same financial investment as a 911 or more. Google RKspyder for a corroboration.


Mike, is this your first Porsche? The reason I ask is I'm surprised you are not already impressed. Porsches can be deceptive in their speed, they're so smooth, sometimes you don't even know you're well above the speed limit.

As others have correctly mentioned, driving makes a huge difference. I'm quite sure Mario Andretti could scare the living crap out of me with a stock Boxster.

PS: 20-30 at the crank would be extremely noticeable, the issue is you aren't going to get there with ecu flashing and exhaust mods. One other thing that will always make speed is to ditch all the extra weight you can, I don't even run a full gas tank.

another thing to note in the hp game is that it is a curve that varies with respect to rpm. as rpm increases hp increases. so, an ecu flash may get you 10 hp, but they do that by moving the rev limiter up a couple hundred rpm; performance isn't changed but max hp at the new max rpm is a bit higher. how often do you drive at 7400 rpm vs how often do you drive at 3000 rpm? freer-flowing exhaust may net you a few more hp, but again at max rpm when the engine is trying to move maximum air. at 1500 rpm the engine actually wants to see a bit of back pressure, so your $3k exhaust is actually robbing from peter to pay paul. cold air intake - what do you think the box has already? in fact, you could argue that the stock intake is more of a cold air intake than the aftermarket units, as the stock unit is completely sealed, whereas the aftermarket units depend on a rubber gasket mating to the engine cover to form part of the seal.

ask yourself what you want - more top-end and max speed, or more honk to pull yourself out of corners? if you want to go fast and straight you may have the wrong car. the ecu/cai/exhaust are a good start, however. if you want something fast out of the corners, start thinking weight, rotating mass and engine load - light battery, light seats, light body panels, light wheels, light flywheel, ac delete, roof delete, carpet delete, underdrive pulley - find out what the racers are doing to their cars.
