Here is a Stage II install on a 1979 928 with a K-Jet fuel system that we just finished. Dyno'd it yesterday.

Numbers: Final numbers were 292 HP and 308 lb ft of torque at the tire, 353.5 BHP and 362 lb ft of Torque at the engine. Up from about 186 HP at the tire, 219 BHP at the engine.

Customer also had us to a brake upgrade, clutch upgrade, exhaust upgrade, radiator and coolant reservoir, and suspension upgrade. Sharp car - a convertible that now goes to have the interior put in it.

Carl, thank you for all the excellent work you put in on this project for me. Your professionalism and attention to detail are top tier and I can't wait to take delivery on it in a couple weeks.

Carl,
That piece that sits on the radiator, that has the cold air inlet, looks like an improvement made since I bought my kit.
How much is that piece?

sstrickstein

How much is that set up? How much HP would you expect on a 1984 928S?

Bob, the aluminum air dam is featured here:

and is a part of the Stage II kits. It is not included on the Stage I kits. It would, however, fit your car.

I could make it for you in powder-coated black finish or brite aluminum finish as shown above.

Yours would have only 1 air scoop, which is sculpted as shown above. I could make it for you for $82.

sstrickstein: you will have to tell me which motor you have in that 1984 S, then I can give you pricing and HP answers.

The reason is, if it is a low-compression motor (like the M28.19 and M28.20) I have a Stage 1 and a Stage II kit for that.

If it is the high-compression, high-output M28.21 or M28.22, then we only offer a Stage II kit.

Let me know.

Here is a picture showing where to look to get the engine number from a 16v 928

M28.20

Carl Fausett

The M28.20 is the US-spec 4.7L engine, 234 HP, 9.3:1 compression ratio, coupled to an automatic transmission.

We offer both a Stage 1 (non-intercooled) kit for that engine,

..and a Stage II (intercooled) kit for that engine

Dyno charts below for your exact engine/transmission with each kit. Sorry for the disparity between the dynos - these two charts are sort of hard to compare.

Please let me know any other questions you may have.
