Dyno surprise
Edit: Sorry, You 993 folk can ignore this post as I went to the wrong board. The Turtle is a 964.
I had the shop take my Turtle in to have it dyno'd prior to doing some "enhancements" and was surprised at the result: 244 rwhp. I expected about 220. It will be intersting to see if it has an aftermarket chip in it already (it's not supposed to). I'll post the results once I have them in hand and post the "after" results too. My car currently has a cat bypass and a secondary bypass but the stock primary muffler and a "cup" airbox (ie, no lid). I use 100 octane gas.
FWIW, I have not seen the plots (I got a call at home last night to get informed of the results) but I'm told the car is running really lean above 5k and hp drops significantly above 5k too.
I'm having an RS LWF/clutch added and a new chip and exhaust (headers without heat exchangers and exhaust that will meet the 92 db requirements at Laguna Seca). As the Turtle is track only, I can be a bit more aggressive than those of you with dual purpose cars. I'm looking for a minimum 20 hp improvement.
So, the point of all this - based on a search, I think Joey and a few others have done dyno runs with cars similar to mine currently and only seen about 220 rwhp. Who else has done a dyno run? What did you see with what sort of setup?

What dyno did you use? Most dynojet runs on *healthy* 993's should be in the 240's if temperatures (air & oil) are moderate. If you used a mustang dyno, those are strong #'s indeed.
