RWD conversion for the 911

[Steve Theodore]

Hahaha...OK I'll just leave it by saying that I cannot personally feel the difference of 72 pounds (of fuel) in terms of acceleration via my poorly calibrated butt dyno. I do notice that my chin spoiler will scrape on some driveways when I have a full tank though, and those same driveways won't be a problem when I'm down to a quarter tank...so at least I'm noticing something.

Well you are more inclined to feel a lead weight placed into the front of your car for one drive and then moved out for the next drive than to feel the gradual loss of fuel as your body adapts to what it feels at the moment so the effect is lessened since it's done over time and not all at once. And like I said, the drag too.

Kind of like when you take a dump and it doesn't stink when you walk out the bathroom, but when you walk back in you almost pass out. Gradual stinkage back to shock.

hahahahahahahaahah

That's a darn good point (about the gradual versus sudden weight). The dump analogy is pretty good too.

I had this done recently to my car... and i really do like the way the car feels compared to before. I must admit, I haven't taken my car to a road course since, so that will be a fun little experience next time out.

I was researching this not too long ago and found a post here where a guy installed 996 GT3RS uprights to improve the steering geometry with the RWD conversion. It appears to be bolt on and an alignment, but the parts are 1600 for the uprights. I'm not sure if the GT2 uprights are the same or better than the GT3RS. Maybe worth looking into if you go through with the conversion FYI. One thing is for sure, you will probably stretch more life out of your clutch with RWD. But the clutch $ savings may be spent on rear tires. I don't think you can put enough rubber in the rear to keep traction with RWD even on a stock turbo.

The 911 Turbo uses an all-wheel drive system based on a viscous multi-plate clutch located directly behind the front differential. Weighing only 120 pounds (54 kg), the all-wheel drive system in the 911 Turbo qualifies as one of the lightest such systems in the industry.

Porsche equips the 2004 911 Turbo with the Porsche Stability Management system (PSM), an innovation the automaker first introduced on the 1999 911 Carrera 4. Using data from several sensor inputs, PSM can detect a loss of grip at the front or rear and reduce instability by applying braking to individual wheels and, if necessary, altering engine power. PSM can help keep the 911 Turbo going in the direction the driver steers, especially on slippery roads.

The PSM system operates so quickly that most drivers likely will not feel it making corrections, and, if activated, the system operates whether or not the driver is using the brakes. The driver can disengage PSM with a dashboard switch, but, for safety, PSM will engage under braking and then disengage when the driver lifts off the brake.
