88 TII Dyno (few mods)
Here is the dyno that the previous owner of my car did. I have an S5 Turbo and manifold to go on now (He said he thinks the stock turbo is on it's way out), and a warlbro fuel pump. I'll probably also grab some 720cc secondaries, and a MBC to up the boost a tad. Also, the TB mod has been done since this dyno, don't know how much difference it makes. Anyway:
Stock Motor (140,000 miles), Stock TB, Stock injectors and pump, Stock Turbo and Wastegate, Stock ignition. Emmissions stuff still on (airpump, cat, etc).
Mods that mattered: Cone intake w/TID mod, Down Pipe, Highflow Cat Converter, RP50 2.5" Catback.
Rock solid 8lbs of boost reading on autometer guage
MAX HP: 215.7 MAX TORQUE: 186.8

It was running pretty dang rich (especially for the stock fuel system I would think!), even after he leaned it out 8% on the S-AFC. The red line is the leaned-out run (not much difference). With more boost and a little better tuned fuel curve, should put out some decent power

i'd richen it up in the midrange there and lean it out in the topend.

You're running lean in the mid range, from 3500-5500 it looks like mid 13 air fuel ratious!! Get a walbro on there, the stock fuel pump is the weak link of the fuel system.

dang that's a peaky torque curve for a turbo rotary, especially with the stock turbo.
My '90 TurboII had a Kansas-flat torque curve @ 5.5 lbs, put 193.8 at the rear wheels on a mustang dyno (more accurate than a dynojet dyno). Still the sucker ran 13.75 @ 104.8 in the 1/4 mile... wonder what yours will run.
