That's exactly what I meant, if what I wrote was unclear.

Hi Bill,

Gottcha, I thought you meant all S4s...even thou I could have sworn we had discussed that before. I probably misread, just my old age catching up with me :-)

What are the realistic hp/tq gains that 87-88 S4's can expect?

I think it's about 15~20 at the wheels.

..and typically that is in the midrange, not necessarily peak HP. In other words, Power under the curve.

Here is a stock 88(one of Earl G.'s very well tweaked stock 928s) before/after dyno done at the 2002 Frenzy VI event in front of dozens of onlookers.

..and an 85 S Auto before/after at the same event.

This 928 was later found to have some other issues (forgot what it was) but the gains overcame it even in it's decaded state. If I recall once it was fixed it was even better!

This thread brings back memories.. I just found a pic of Earl's 88 on the dyno at Frenzy VI. Actually if I recall Jim Moorehouse had just bought it so technically it was his. There are a few more pics from that day and one from the Saturday Tech session. Bummer, I noticed Scott talking with me in the photo.

I assume these may be copies like DR referred to?

Heh. I just re-read your statement, and it's not what I meant. I didn't think 87 or 88 benefited either. Let's just go with yours.
