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 |

Nope, the peak is dictated by the overall engine combo.
The fact is that below 5,252 RPM Torque is always higher than HP. Above 5,252 RPM HP is always higher than torque.. So HP is not huge unless your engine is very much still revving and making power past 6K. Dyno graphs that don't cross HP and torque at 5,252 RPM are not accurate- the formula is incorrect. Here is an example of a correct dyno graph (IMG:http://www.aircooledtechnology.com/type4/914/2270_performer.jpg) |
