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

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.

Those air fuel numbers would be good on a N/A piston motor; but you don't have one of those. For $.02 I'd fix that spike and richen up the entire band.

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.
