I know I know I know....pics will come as soon as I figure the process out, give me some time. Ohhh she's hot. I spent an hour or two this afternoon fiddling with this and that, I've got everything but the boost gauge done now. I had to increase tension on the alt. belt, wire tie one of the cold air intake lines back (contacting the alt pulley), I had to pull the fender liner(driver side) and tether the new cold air intake(k&n) it was hitting the head light and was a problem for operation, again a simple wire tie. I also finished up the air fuel gauge. I won't get a chance to drive her today but manana, now that's a different story! Oh, and by the way, I'm not sayin... I'm just sayin... your wife might not understand, but it is so worth the time and money to boost! The car is utterly transformed. My only concern is what happens when I get used to this... what's next... Oh the humanity!

Wow, Congrats on a nice project. Is that a late 86 or early?

Now you see what all us boostards have been saying. The 928 was built for this kind of HP. It is truly remarkable how you can take $19k ($11k for the car, $8k for a stage III) and end up with a car that will SMOKE just about anything on the road. It's so satisfying.

Now post some damn pics!

Here are all three (Stock, Stage 1, Stage 3) dyno charts. The stock and stage 1 were performed on the same day:

More power can be extracted from this setup by freeing up exhaust restrictions and adding fuel via larger pump and regulator.
Stock S4 regulator should be sufficient with a Bosch 044 pump.

The tune on this setup is very conservative due to the above restrictions.

^thanks.

what 1/4 mile times have been achieved with these kits

Most performance measurements from all the various options have been posted here:

This is the 2nd 85/86 with a Stage 3 installed, so no drag strip numbers to share.

Visiting the drag strip doesn't appear to be a very popular activity with 928 owners. One of these days I'll take my car to the local drags, need to get the LSD installed first.

Those who poo-poo the self measuring devices should take a gander at this thread:

There are those who don't want to break something, especially MT, parts are hard to come by and expensive, the AT is better suited at least IMO.
