Just back from Mike Bravaro's shop, BodyMotion. I video taped a run of dyno tests as part of the presentation for NNJR's monthly meeting Wednesday May 8th. The meeting will feature Mike discussing dyno testing your Porsche. We ran a stock 993 and Mike had previously done a video on a Boxster-S that he had modified (including a supercharger!!) and a GT-3 cup car. He was good enough to put my 24S on the dyno while I was there and do a few runs. I have mixed feelings about letting everyone know how little horsepower my car actually makes, so if you want to know you'll just have to come to the meeting.

I'll bet it makes over 1200 goatpower.

I haven't been to a meeting in over 2 years, and now I may have to.

just curious, but what kind of dyno do they use? Dynojet, mustang? Results can vary greatly depending on temperature, elevation, circulating air, etc. Blowing cold air into the intercooler(s) of a turbo car can drastically change your times. When taking several runs in a row its important to let the car cool down. I'm trying to learn about dynos and how to dyno a car properly. I've seen a lot of far fetched dyno slips. Any other things which can effect a dyno run?

All good quesions, unfortunately you'll have to wait till the 8th to ask Mike the specifics. I do know that the dyno is an eddy current unit (electric brake) rather than a water brake. Mike's shop is essentially at sea-level (Ocean, NJ) ambient temperature about 60-65 (I'm guessing) and he had a decent air handler. One of the things that I noticed is that they are very familiar with dyno testing. They had a fair idea as to what to expect and at what rpm plus or minus 100 rpm.

I saw you sneak out early, why didn't you let me know where you were headed? Jeez, very secretive Al! Must be contagious in your office . . .
