Maybe you guys might have an idea what's wrong with mine here.
144 WHP @ about 3200 rpm!
241 ft/lb @ 3046
Mine's an '89 Shadow 2.5 w/ a stock TII IC mounted up front, stock swirl head w/ cleaned up ports and mild valve un-shrouding, late model t-II garret turbo w/ 2.5" swing valve, 3" side exit exhaust after stock 2.5" down pipe,
boost graingered to 14 psi
stock fuel system and ECU, A413 automatic with manual valevbody
This was done on a mustang dyno that judged RPM by wheel speed so there's some error from convertor slip I'm sure.
As you can see everything is over by only 3200 and starts to decline, and the hp number is depressing, not to mention how super-peaky the torque is.
What might be the problem though? I changed a couple things since then, I replaced my 180 degree t-stat with the stock 195 since the engine runs VERY cool and it has a large aftermarket fan. Also I read up on that barometer solenoid by the MAP sensor and have re-installed it after learning what it does.
I do notice slightly more power, mainly after putting the solenoid back in, but still not enough to even claim Timmay's WHP with his little Mitsu turbo. Is a re-cal in order?
