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. |

Exactly....
Thats really apparent on engines that make all their power below and will not even rev 5,000 RPM- Like my Pinzgauer engine... My whole point is that HP is way over rated and generic for street cars that spend their at midrange RPM. |

The only cost effective way to get reliable HP is to go with a six. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

Jake when you can sell a 150 hp engine for around $7500 my mind will open to the incredible possibilities offered by your genious with T4 engines. My sense is your production volumes will never get you to that price point. So I'd rather pick up a used 6 with a warranty for under $5000. |

Isn't a 2270 kit in that ballpark?
Me, I am trying to get a 80hp 1.7l rebuild for Blair's 72 on a small budget.......but he has eyes for my 2056 engine. (IMG:http://www.914world.com/bbs2/html/emoticons/flipa.gif) |

Yes, thats what we are putting together, a stock "W" code engine. The one with domed 90mm pistons and little valve heads.
I can see a turbo in the future..... (IMG:http://www.914world.com/bbs2/html/emoticons/popcorn[1].gif) |
