04 Boxste S Dyno Test Results

[harryrcb]

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.

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.

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