For those of you with a 1985/86 32v 928, we now have both a Stage I (non-intercooled) and a Stage II kit (intercooled) available.

Although we developed our Stage I kit quite a few years ago, we never went on to work up an intercooler for Stage II. The challenge was the space envelope available for the intercooler, which, with the pipe-organ manifold, is quite limited.

This December we got our hands on a beauty of a 928 S3 5-speed so that we could take the time to engineer the best possible solution. Our intercooler is a thing of beauty, and flows extremely well, as you can see by the pictures and the HP results we achieved.

The 1985/86 32v 928 is reported at 288 BHP, but our test mule arrived with the cat already deleted and a non-standard exhaust, so we base-line tested it to get the accurate "before" number for this car and it came in at 306BHP (260 HP at the tire). A very healthy '85 32v 928.

After supercharging, it now made 460 HP at the engine (390 at the tire). What a blast to drive! This week the car goes back to it's home in Pennsylvania. We can ship this kit with instructions, or you can bring your car here for installation too.

More information is available at our webpage for this kit here:

Here is the YouTube video for it:


...and a few pictures

Enjoy!
