How much power have people been able to get out of a stock displacment motor? Torqure and Hp?
I can recall reading about people getting 120hp from 1.7L type one motors years ago. That is on pump fuel. With the technology available today I would think that volumetric efficiency could be pushed further than before while maintaining reliability on the street. So is 130-160hp out of a 2.0 totaly (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif) I know Porsche did it years ago with a couple diferant 2.0L motors like the 901/911 or 587 (street motors not track). However, they were radicaly diferant compared to the simple type 4. .... -Rob |

Jake, hp (sae) = torque (ft/lbs) x rpm / 5252. The 5252 is just there to correct the units being used. If one used Watts for power and measured torque in Newton meters, the correction factor would be different, and thus where they curves crossed on the graph would be different, but the results would be just as valid.
You can also show graphs where HP and torque are plotted on different scales, and there, the curves would also cross at a different place, but would still be valid and correct. There's nothing magic about 5252, it's just a result of the units being used. |
