I was reading the Excellence article about the budget 912 racer and the owner claims 140hp out of the engine. They didn't talk the about the price of getting that kind of output from 2 liters except that there was alot of head work and special pistons were used. ($$$$) Anybody have an idea of what it costs to get a reliable race motor with that kind of power? And, if you can do it, is it only a track motor or could you autocross it also?

All it takes is time, money, blood, sweat, and tears. Mostly tears at looking at how much money you spent...
All you have to do to get power out of a motor is spin it fast enough. The real $$$ comes in making sure that it can use that RPM effectively (that's money spent on flowing the heads, etc.) and on making sure it can stay together for a little while at your target RPM. A "race motor" can run on race gas. I believe 105 octane is available, and I know that 100 is. So the compression will go up--and up--and up! Couple that with a very lumpy cam and heads that flow very well (and more compression because the cam "bleeds it off"), and it's not hard to get to 140 HP. The EP guys used to get 140-160 HP routinely out of 1.8 liters, so getting it from 2.0 liters should be a little easier! It will cost cubic dollars, though. And don't expect to put too many hours on it before you need to "freshen" it up. SWAG? $10K development, $5K+ build, a couple grand for every "freshening". --DD |

KT I see you've been hanging out with Grant (IMG:style_emoticons/default/smile.gif) actually, his question was a little vague, is he talking a true 912 motor or is he asking about building a Type IV? Does he need a "race" motor or is he just using the term loosly? |

Aaron,
I think if you took that core all the way to stuttgart and asked Porsche to rebuild it, they'd smelt it down and build you up a new one with the metal rather than refurb it (IMG:style_emoticons/default/tongue.gif) |

Look at the question in the original post.
Very specific. "Anybody have an idea of what it costs to get a reliable race motor with that kind of power? " that was all... KT |

KT yea sorta specific but could be asking the wrong question..."why" a "race" motor when one can get that power from a street engine?? "race" engine is too broad of a term and is often misused |

140hp is a well tuned street 2.0. It could be built for less than 5K if you watch where you spend your money.
