If you have been following our Facebook feeds, then you know that our Stage III kit development has been moving along for over 2 years.

As this kit represents the best of everything we have and can do, I wasn't going to rush it or release it until after it had been on the road and running well for a while. Add to that the fact we first built it with a Raptor RH supercharger, tested it, didn't get the numbers we w anted; took it back, redesigned to use the ProCharger P-1SC-1,, tested it, ,didn't get the numbers we wanted; took it back, re-designed for the ProCharger F-1A supercharger - got the numbers and the durability in the package size we wanted. It took a while.

Cut to the chase 1: We did well over 500 HP at the tire and over 600 HP at the crank on an otherwise stock 1991 928 GT. Dyno charts posted below.

Your experience with this kit is likely to show even higher numbers, as 1) my test mule has 216,000 miles on it and the engine is good, but not great. A tight engine would post even higher numbers. 2) all our numbers come from a eddy-current dyno (Mustang) and not a inertial-drum style dyno (like a DynoJet) which often yield higher numbers.

But it really doesn't matter so much at this level. As our video shows
www.928motorsports.com/productdemos.php
you can light up 295/35/18 rear tires in both first and second gear, third too if you have an abrupt clutch foot. I can assure you - its plenty!

Cut to the chase 2: It isn't a cheap kit. This is our ultimate kit. We already have kits for the 928 starting as low as $4695

In this kit we include everything (new fuel pump, injectors, adjustable fuel pressure regulators, fuel rails, SS braided lines, intake spacers, intercooler, and more and more - even a new injector wiring harness and new spark plug wires if you add on the optional Electromotive engine management. Very very complete, very thorough.

That brings it in at $12,760 for the Base Stage III kit and $16,060 with the optional EMS.

Here are the dyno charts.

The third line on the graph chart is boost pressure.

Wheel HP: 523 HP at the tire. After temp correction, 516.6 at the tire.
Using a 15% drive-train loss (manual trans) that's 615 at the engine before, and 607 BHP after.
