The air is getting thin here. If not spec 996 what prevents it from being spec 996? You're posts need to be a little more specific(detail to the bone) if someone is going to shell out $60k. 356 hp off the crank on a 3.4 is hard to believe too. Do u have pics of car weight etc. ? Mike

The GTC4 class is specifically for 05'-09' 997 GT3 cup cars....
Exactly what motor does it have?

Oh horse ****. I don't event think a blower can get a 3.4 to those levels at least not for long....
I have X51 headers to Fabspeed's X pipe to open pipes, GIAC's flash, and a few more tricks and the most I've ever dyno'd at was 282 at Miller which is 4500 fsw. At sea level I was 272 so allow me to be the first to call BS.....

Also long time head tech (30+ years) at the P dealer here told me he can get very little if any power increases with a flash on any N/A Porsche. I know a flash will just alter ignition timing and possibly fuel mixture which should already be optimal with the OE FI program (ECU). To really get more power, you need higher compression, larger valves, more aggressive cams, higher flowing ports and throttle body, less restrictive exhaust. Spinning it faster won't hurt either. Furthermore it all has to work together or it could very well make less power than stock.

The only dyno I put any creedence in is "The Great White Dyno" aka the Bonneville Salt Flats. I've run there and it will make a believer out of you!

theoretically a "tuned" 3.4 x51 with lwfw, cats, headers and no mufflers could very well push 305 whp... although I've never seen one.

no that's not the case.... the 3.4 engines and version of bosch motronic respond much better to a tune than any of the 3.6 later motors... a GIAC flash for a 99 3.4 motor will definitely give you a boost north of 4000 rpm !! your mechanic was probably referring to the 3.6 motors that don't get much extra only because of the later version of motronic software that controls the engine... earlier version of motronic according to the experts had more "variables" available for tuning....

hmm... how many miles did your older engine have on it when you dynoed it?
