Need advice on making boxster quicker.

[23109VC]

the BMC drop in filter really makes a gain you can feel? is it a paper filter like stock or more of the cloth kind like a K&N?

is this the kind of filter that supposedly can hurt the MAF??? I just dropped $$ to buya new MAF and am in no rush to ruin it and have to buy anothe rone!

You can spend thousands and only gain minimal HP the factory left as headroom...the only way you'll see appreciable gains are in increasing displacement. Any forced induction system will greatly reduce the life of already questionable internal components.

A properly installed turbo kit is about $10K and if you push the motor hard you will need another one of those shortly when it grenades at around $15K. The factory 986 was simply not designed to work well with FI. With enough money anything can be done, but does it make sense on a fairly light weight, high compression motor?

Suggestion:
Learn to use all of your car first. A 3.2L Box S is a formidable track weapon in the hands of a skilled driver. The Boxster Spec racers are already turning lap times that rival 996 Turbos and GT3s at the track and they are running bone stock 2.5L pea shooters (stock intake, stock headers, stock internals). If after a year of DEs you still need more HP just drop in a 3.6L.

Did anyone tell him he bought the wrong car yet?

Seriously, the 986 platform just don't have the support for engine mods except the 3.6/3.8L swap which is perfect if it's done right.

987 guys have TPC Racing turbo kit, Sharkwerks RS350 kit that have been proven over and over again that they work.

Yep, the $20k plus question that has ghosted these boards for years. " HOW DO i MAKE MY BOXSTER FASTER".

With out doing major damage to your engine, There really is no miracle cure, except a 3.6-3.8 engine swap for $20k+. Any other gains you get will not be cost effective. I have searched high and low, read many articles and threads on the subject. There are many claims out there, but none have been substantiated with real proof. You can desnorkle your porsche and it will sound faster(cost=free). This car wasn't made as dragster, but it will eat 99% of all cars up on the twisties(curves). So anybody wants to race you, well make sure there are plenty of curves and you will crush them. Mustangs, Vettes, camaros.... will struggle to read you liscense plates around the twisties.

My friend has a 1985 supra twin turbo, which is by all means is one mean mutha!! He keeps wanting to race me, but I always reply, "that's not why I got the car". So as his only sees the road a couple times a year, I enjoy mine about any day its not raining!!

There is a reason Damn near all Boxster drivers are smiling when you pass them on the road!! The boxster is the ultimate all around driving experience!! So Just enjoy the ride!!

Why only when it's not raining! I had great fun this week in a light rain. Turn off the PSM, and do some power-slides like you have a big V8!

Welcome to the forum!

Do a search on intake manifold and headers to learn all you need to know about "gaining" HP. You'll find it's expensive ($3-4K) and these mods are only worth about 20-30 hp combined. Not a good investment. Plus pay attention to all the references to CELs popping after doing these mods. A lot of headache for very minimal gain. Throatier mufflers fall into the same category. For the money you'd spend on these 3 mods plus what you've got invested in you box, you could probably find a 987S that would have just as much or more HP in stock form.

Believe the previous posters when they say the best bang for your buck is to swap engines with a 911. If that's not a possibility and you absolutely crave more speed, sell your box and get something else that fits your needs. Your bank account will be miles ahead and you'll be happier too.

Sorry for the reality check, but Porsches are not cheap. We don't want you to go bankrupt chasing a few HP gains.

Well spoken and good advice.

It's been said for decades: there's no replacement for displacement. My 3.6 has given a couple of Carrera S 997s more than they liked.

Yes, chances are it will kill your MAF, so you get 0.1 hp increase but pay $250 for a new MAF, sounds like a good deal - right ;-)

[ChrisZang]

Here is my "Top 10" of what makes a Boxster faster

1. Driver training (lots of A/X and DE)
2. Suspension upgrades:
a) Tarrett front and rear sway bars
b) PSS9 coilovers
3. Stickier tires
4. 100 or 200 cell cats
5. Pedro's "Techno Torque" or the IPD plenum
6. "cold air" high flow intake
7. "test pipes" to replace the secondary cats (warning: "barely legal")
8. less restrictive exhaust
9. lose weight
10. Softronic chip tuning (ECU flash)

Ive never heard anyone with a BMC airfilter having MAF issues because of the filter. The BMC comes pre-oiled at the perfect amount, you can barely tell its even oiled. As for the K&N it comes with a pound of oil which triggers the MAF. Also you can just hear more air being sucked in once i replaced it from the OEM.

Also since its a used car im sure you will need to do a minor tune up and why not change the OEM filter for an upgraded one. 80 bucks on ebay.

Well, it killed my MAF (see my signature)
But in all fairness this happened after I re-oiled it strictly following the procedures by BMC (I was actually using LESS oil than they recommended in their instructions)
