04 Boxste S Dyno Test Results
A number of you have asked me for hard numbers on my Boxster S and I guessed around 295 FH , but that was only a guesstimate, Turns out I was not far off. Check out this video of the dyno run. The run was made on a Dynojet which is not known for high number but I believe more realistic numbers. I may have lost about 2-3% due to the high temp and humidity we had today and some even believe those wide wheels I’m running are sucking down some hp but that’s OK - I'm happy with these numbers since I did all the work myself.

Does anyone else have any dyno results? I would like to see them

What all have you done to your car to get 290hp at the fly wheel?

Not that much, Cold air intake (manufactured myself), headers, mid pipe-no cats(made myself)Borla Muffler(slightly mod) DME by Softronics, Technolabs planum and the rest was just to keep it together with oil issues (AOS,deepsump,cooler thermostat,etc) and cosmetics a good solid gain of about 35 HP at the rear wheels.

That is correct, the last time I dyno'd my 01 S I got 212 hp

My stock 75k mile 2000 S made 224hp, 212 Tq at the back wheels. Mustang Dyno which read a little high.

Yea, you know it's funny how much difference there can be among all the different manufactorers of Dyno's. The first time I took mine to a tuner shop, before I made any changes, the guy came up with 253hp, I told him that's impossible cause the FWHP was 259, so he made some ajustment to the machine, made 2 more runs and came up with 237 and 241. Needless to say I did not go back to him. yes it sounds impressive and with my mods it would have made around 300 whp but who are we kidding? mainly ourselfs, that's why I went in search for a guy who was down to earth and his machine was not all hyped up.

The worst dynos are the units that are in "tuner" shops where people go there to see what peak numbers they make. I use all 3 of my engine and chassis dynos as tools, generally not caring anything about the peak numbers, but rather the efficiency, AFR, EGT and BSFC numbers that we see. The other thing I tune for is torque and a flat torque curve.
These things equate to a better performing engine all around- period. Engines that are tuned for "Horsepower" are virtually worthless below 5,252 RPM, run rough and are a ******************** to drive.
Dynos can be the best tool in the shop or the worst, its all according to the mindset of the shop, the operator and the application. Most of my engines generally leave here with LESS peak power than they made during the best dyno sessions. I sacrifice net peak power for a flatter and fatter torque curve and the car is ALWAYS faster and drives better.
"Tuners" may argue, but they generally would not know what the piston from a Boxster was if it fell from the sky and landed on the floor of their shop.
I chose a dynojet unit for my chassis dyno for many reasons, primarily for repeatability and because of the sampling method. Many cars I dyno here are repeatable within 1-2HP and torque on other dynojet units, even older or newer than mine. Other dynos are much different.

Jake,
You still have the one shop in GA or do you have other shops qualified to do your IMS retrofit kit?

Coming from the world of forced-induction Audis, I second this mindset. Most of the time cars similar to mine would put up bigger peak HP numbers. The big difference in cars was only the tune. When I would swap cars with other people just for kicks, they would always say mine was faster. Area under the curve is what makes a car fast.

Just one location. Thats all I plan on having as I am generally a control freak that has to orchestrate the procedures precisely.
The IMS Retrofit procedure is something that we originated, so I feel compelled to keep it under this roof where the first one was carried out with the hybrid ceramic bearing.
I have cars shipped here routinely, we have cars here now from Florida, Nebraska and one on the way from Canada.
See this link to an article I recently finished detailing the procedure. http://www.flat6innovations.com/services/intermediate-shaft-retrofit
Now, I don't want to hi-jack this thread, because it wasn't about the IMS procedure, but rather dyno tuning..
Using a dyno to get a big erection from a huge peak number may satisfy some, until they get spanked by the same car making more usable (average) power and less peak power than theirs. Then that erection goes limp pretty quick and you'll wish that you had the car tuned by someone like me-
