looking for more Horsepower

[RandallNeighbour]

Have you been to the track with your local PCA for a high speed driver's education course yet?

You may not want more HP if you do this. It's a great cure for horsepoweritis, or at least it was for me.

To get enough HP to really make our model years feel fast, it's gonna cost ten grand or more. I am saving that money for a newer and much faster Cayman S instead of modding my 97. The 2010's have a new motor in them that doesn't have an IMS and may be the most bullet proof motor Porsche has made to date... that's the motor I want in my next pre-owned Porsche, and it will have gobs of HP compared to my 2.5.

Lots of good advice here. I enjoyed reading it. A Boxster can gobble up a grand PDQ. As you get used to it, especially if you take it on the track, you'll find that there is lots of stuff that you "need". Suspension parts are all expensive. A set of halfway decent performance tires are a grand or more and the rears only last 12-15,000 miles with cautious driving.

Welcome to the fold. My advice is to do a lot of reasearch and thinking before parting with your $s for a few HP.

Just realized something. A thread just like this is started every single month... all new owners of the older base models want more HP.

We should get BruceLee to make a sticky thread that's got all the HP mods on it so we can point people to it instead of rehashing it all the time.

Over time I have tested most every exhaust system on most every size engine. I have yet to be impressed, either on the dyno or on the street.

I have seen a 3K exhaust system cost an engine 20HP, or a set of cheap headers add 2HP to another. I have yet to see the gains that make the drone at cruise speeds or the cost worth it.

This year ALL of my updated engines were fitted with OE mufflers, I carried out the development for my engine program and apply what works.

If you like sound, go for it. If you want less weight, go for it.. If you want HP, reconsider.

I have a great setup I feel with some influence from Jake. I am running turbowerx headers with fabspeed bypass pipes and a S muffler. The car makes great power, I do have a cel BUT the one thing I do not have is any drone what so ever at any speed,rpm,top up or down, etc. The car is loud as hell too.

Mike has taken notes of many such discussions and written an article "So it isn't fast enough" on his web site. It isn't interactive like the forum but it does get updated with any new thing that gets to his attention that seems to matter. It's kind of like his "What can you do if your engine is blown" article. Intended as a decent place to start people reading and then they can come back with questions.

So provide people the links and you won't have to endlessly repeat the same stuff

Mike has no commercial affiliation.

Jake is correct . Its all about the sound and the benefit of weight reduction when it comes to an aftermarket cat back exhaust. Under the best of circumstances, one might see a slight bump in hp. However, claims of a 10-20 hp increase on the part of some manufactures is extremely unrealistic .
