I would really like to know what you have for 914 in the way of a hi mpg, respectable performance package.
I figure the 914 should be able to kick out 40+ mpg and get a 0 - 60 time in under 7 seconds. The new tdi jetta coming available in July will go 0 - 60 in 6.9 seconds and get 41 mpg in the city and 53 on the highway. However id does weigh 3300 pounds. I figure the 914 should be able to smoke that with the 1300 pound weight advantage. I am really looking forward to seeing what you have come up with Jake. trying not to hi jack the emissions thread but keep it on 914 world (IMG:style_emoticons/default/beerchug.gif) BTW you said you need 10 or 12 additional people. I would be # 2 ... I would gladly buy a super efficient 914 engine as opposed to buying a tdi jetta. (IMG:style_emoticons/default/beer.gif) |

As I said in the earlier thread, I am #1 in line... (IMG:style_emoticons/default/biggrin.gif) I can't wait to hear more (IMG:style_emoticons/default/popcorn[1].gif)

The high mpg engine is already in the pricelist. It's called the SUPER 2 liter

Jake's in the business to sell engines. That said, I wouldn't hold my breath for lots of technical data shared... proprietary info and all, ya know?

The Super 2 Liter isn't cost effective to build... AND it is very difficult to assemble, so it could never be a candidate for an engine kit.
What I **could** develop would be based on a 1911cc foundation. This keeps the price down and simplicity to assemble way up. The goal would be 45 MPG and it wouldn't be hard for us to attain stealing some technology from the Super 2 Liter's success. We would use 1.7L HAM prepped heads and more than likely we wouldn't any exotic components in the recipe for the engine.I would not use our AMC "LE" head castings for these due to the intake ports characteristics lacking the critical velocity that we need for insane mixture quality needed for the drive-ability and MPG goals of the engine.. |

Yes, L Jet compatible versions would hit the ceiling at 110HP, carbs about 120.
This is a realistiically economically feasible combo that could be easily assembled- remember, we aqre looking for a good mix of power/driveability/MPG/reliability/longevity with all being equally important, hence the conservative displacement. |

Jake;
I have a 2.0L original engine now. How much will I have to trade out to use this? Not just a money issue, but I would really like to try to keep my 2.0L engine somewhat intact. |

Do you think adding efi to the mix could bump an additional 2 or 3 mpg vs L Jet? |

Eric, buy a 1.7 core motor. (IMG:style_emoticons/default/wink.gif)

Eric,
I imagine you wouldn't have too much trouble trading your 2.0 for a 1.7. In fact, I might even be interested. (IMG:style_emoticons/default/wink.gif) |

Pete,
Yeah.. I'll ring you this evening.. Keep this realistic guys... If you have the money for programmable EFI- you also have the money to spend on a Super 2 Liter... There are constraints we must work around on this one: Prioritized MPG cost reliability longevity performance That means making an engine that needs no special support equipment! No 2K headers, no external oil coolers or DTM systems, cost effective ignition and induction. Its a big picture and I'll tell you now that programmable FI would not be cost effective on this one, it would cost 3K to get 2 extra MPG. do the math. The 1911 base engine would be easy for 2.0 guys to source a complete new core to build the engine from and the 1911cc parts are dirt cheap and VERY strong!! I think the best way to proceed with the design of the project is a "you design it, I build it" approach... I'l start a thread on my forums where I'll give a list of goals and give a list of available components along with a list of objectives. We'll get everyone involved designing the engine online. Then I'll build it, dyno it and optimize it. But all that critical info can't be shared where I don't have all copyright control over it, unfortunately.. |
