HP gains - 986 Forum - The Community for Porsche Boxster & Cayman Owners

You could knock a easy half second off your 0-62mph time with a Powerchip,without any loss in your powerband(you have to use 93 octane though). The part is on page 25 of Performance Porducts magazine. Gains on a 2.5L are 18HP and 16Lbs on 93 octane,2.7L are 19HP and 15Lbs(up to year 2002). You can knock off that half second for only $840.00.
Added with that you could buy a Powerflow Kit from Performace Products on pg.27 which gains 13HP for $445.95,but I have no clue on its effects over the whole powerband.
So for only $1500 with installation you could be running a 2.5L Boxster with a Boxster S.
Keep in mind I have on clue what these parts would do to how long the car last or drives.

I have no doubt that the catalog indicates the data below. I have to say that based on the input of folks here on the Forum, there is no way you are getting this kind of performance enhancement. Not even close!

However, we always suggest that folks here try these mods IF the seller will warranty that the HP gains are verifed by Dyno. If not , the seller should warranty in writing that they will take back all mods and provide a full refund plus shipping.

Seems fair, no?

And what about the usual HP mods, exaust/headers, etc, im sure it does something right? Also, what catalog is this, where can I view it?

Hi,

You're absolutely right! Headers can make a difference. But again, only 10-15 HP and for about $1,700-$2,200, so we're right back again with the estimated $1,000/7-10HP ratio.

Also, Headers do little to enhance low-end performance (torque) and may actually impede it.

Finally, it very much depends on where this extra power is formed - where in the RPM range. If all the power gains occur at 6,000RPM (and this is where they usually do), all it is really good for is to produce Dyno or Time Slips as these are usually the only two places where you will regularly run in this range. Plus, there is almost always a corresponding decrease in HP/Torque somewhere else in the PowerBand (usually the Mid-ranges), lowering your Net gains as well as making the car less powerful in day-to-day. The power isn't really usable...

Happy Motoring!...Jim'99

As far as mods go, I have done the B and B exhaust and the Evo Cold air intake kit with excellent results. I definately notice more low end power in daily driving. Most noticable was the sound of the exhaust and intake, it sounds like a different animal at full throttle. My buddy with an 02 911 C4S drove my car without the mods and the weekend after the mods and immeadiately noticed the difference and in fact has ordered exhaust and intake kit for his 911!

Now I havent dynoed the car yet, but given the results that I have experienced, I dont really care about the numbers... I can FEEL the difference and that is what matters to me.

Cost: 500.00 for the intake... 135.00 for the install
810.00 for the exhaust and 50.00 for the install

Total $1495.00

Increased driving satisfaction...... PRICELESS
(cheesey, I know, but it somehow works!)

mind you I am in the car business and the installs were mostly
favors!

I will invite anyone in the Phila area to come and drive my 01 S
and feel the difference... with my supervision of course... haha

Happy motoring,

"with my supervision of course... haha"

Then, all of our fun was sucked out of us!

does anyone have a 911 engine swap done on thier boxster, or know anyone who does? I know I'm not the only one to think of it and have seen it before. There was one for sale in Dupont Registry.

On a side note, does anyone know if an aftermarket spoiler for the 987 that replaces the stock one would fit on a 986? (Speedart 987 roadster spoiler)
