Stage 3 911/930 Carrera Turbo system (1984-1989)

Boost your 930 turbo or 911 3.2 Carrera with a Protomotive turbo system upgrade.

The Stage 3 is offered in multiple configurations.

  • Stage 3 J tube (930 style)
  • Stage 3 on-the-side (using oem heater boxes with the turbo by the valve cover vs. distributor)
  • Stage 3 headers
  • Stage 3 twin-turbo
  • Stage 3 custom

Each system has it’s benefits for either fitment, convenience, diy, race and of course performance!

The Stage 3 turbo systems main signature is and upgrade to 97mm 3.3 liter 7.0/1 compression ratio running the oem p/c’s to allow higher boost pressures on pump and race gas while retaining oem reliability.  (98mm / 3.4L also available)

Running on pump fuel, the performance ranges from 530 to 620 crank hp.  While with some meth injection of ms109, mid / high 600’s is possible.

A 3.4L twin-plug / twin-turbo build with Protomotive’s Pressure sensing Motronics software is an amazing build with super response and power to compliment anything from a sleeper to a wild wide-body conversion.   Producing approx 625hp crank on pump fuel, using all of the oem electronics, these systems can even be maintained at the dealer with oem diagnostics tools.

How Dual Disc Clutches Work and defy basic physics What are the advantages of dual disc clutches? The main advantage of a dual disc clutch is that it can handle more torque than a single disc clutch because the two discs provide twice the surface area for friction which allows them to dissipate heat more effectively. Hmm... well, kind of. Doubling the surface area does allow twice the surface area to reject the heat and it does provide twice the surface area for wear so you get longer life out of them versus an equivalent single disc clutch. Dual disc clutches are also less likely to slip than single disc clutches which makes them ideal for high performance application which makes them ideal for high performance application. Yes that's true as well and actually the whole point of going to a dual disc clutch versus a single, but still not answering why they hold more torque when the basic physics equation isn't making sense yet. . .

How Dual Disc Clutches Work and defy basic physics How are dual disc clutches designed? As you can see, dual disc clutches are similar in design to single disc clutches since they both use flywheels, pressure plates, clutch discs, and so on. But the major difference is they use two friction discs instead of one, which is a hint to the answer we're after here, so remember that. The two discs are mounted back to back with a floater plate sandwiched in between. When the clutch is engaged, the pressure plate forces the two discs together, which transmits power from the engine to the transmission. Well that gives us a little more information... Here we have two discs- so we have doubled the surface area which should double the torque, right? Well from above we had f=uN, where f equals the sliding force provided by the u part which is the Coefficient of Friction and N being the force pushing them together, also known as the Normal Force. Hmm there's no surface area even in that equation...what gives? So, doubling the surface area isn't what's giving us the increase in torque holding capacity....or is it? 🤔 . .
