Boxster S Stage II Upgrades....

[wild1poet2]

Thanks again Doc, Those dansk pieces look great. Now I'll have to be on the lookout for someone with one so I can check out how they sound.

You mentioned the stage 3 mods adds 35hp and 37lb of torque. Do you have any dyno charts you can share with us? I'm curious about the range of the increase - I saw one where the increase was significant only above 6000rpm.

Even if the major gain is above 6,000hp(which it probably is) that is not a huge drawback. When you want max accleration you floor it and shift at red-line. People complain about lack of a power increase or even a loss in the low and mid-range but when I want to open it up I don't shift at 5,000 rpm.

Hi,

Hard acceleration calls for Torque more than Horsepower. Even at 5k RPM, you're already past the Peak Torque.

Power is Power to be sure, but the Best Power on a Street Car is Usable Power...

Happy Motoring!... Jim'99

Sure, torque moves you down the road but without hp you go nowhere. They have a direct relationship. One memeber on here made a good analogy regarding TQ and HP. He said if a large waterwheel is our engine, then torque would be the size of the buckets and Hp would the rate at which the wheel spins. The best power band in the boxster would be between the TQ and HP peaks which would be between 4,600 rpm and 6,250rpm in the boxster S and 2.7Ls. However, in order to keep the boxster in the upper portion of the power band shifting above 6,250rpm is necessary.

Wow, ever have one of those days where you respond to a post in your head, but don't type anything? I don't have any dyno charts handy on the Stage II + secondary cat bypass pipes, but next car i do them on, I will see if I can work a couple of dyno runs into the deal. I had some on our dyno computer for a previous car, but the computer took the "big" one, and we lost all of our dyno runs from the first 6 months we had the dyno. I'll see what i can come up with.

I agreed with MNBoxster, I get the most enjoyment with usable power on the street. I installed an EVo air intake several mths ago and I love the sound when I push the car above 4500rpm. However, I only enjoy it for a few seconds in the city since 2nd gear redlines at about 70mph.

I moved to an S about 6 months ago and I felt the difference throughout the range from my old car.

If there is a 35/37 increase in tq/hp with the mods as PorscheDoc stated, it'll be like moving from a regular Boxster to an S. Also, I think it'll sound awesome.

I figure it's about $3500 with all the mods installed. Worth it to do? Let's start a discussion.
