Yeah... kind of confusing... Your car has a 4.9 liter V8 engine. Earlier model Cadillacs had 4100 which is 4.1 liter and much less power.AB91'coupe said:i got a question what size number is my cadillac HT4100,ect. and how much horsepower does it bring=? ihave a 91 cadillac coupe deville, 4.9.
Stock at the wheels has been measured to be about 164 without any mods by some people (Caddyinfo.com). When I finished my mods, I have seen 204 at the wheels...Not too damned bad at all...:lildevil:medicz28 said:I used a G-tech and pulled 150 RWHP with a rider. Figure 200 flywheel, minus 20% drive train loss. equals 160. The car was stock at the time w/110K and orginal everything expect air/fuel filter, PVC and 16" CTS rims. I just changed the EGR value and solenoid, added a Flowmaster 80 series with quad tips. Ignition tune up is next. Not much, but the EGR and tune up, will hopefully bring me back to 155-160 stock area. I can't see the flowmaster giving anything but a better sound.
