If you've got this arrangement, what are you getting for MPG's? Curious to see how you do.
Thanks. |

Ljet. She ran great this past weekend, 400 miles each way. I'm just not thrilled with my uh, fuel economy.... (IMG:style_emoticons/default/hissyfit.gif)
37 mpg is incredible! |

Last summer I was getting somewhere in the low 30's at 85ish on the autobahn. The Germans put ethanol in their fuel now so it could be better. I am running D-Jet and have the mps adjusted to run pretty close to 14:1 at cruising speeds.

D-jet. I'm getting 25 in town and around 32 highway. That is, when I can keep my foot out of it.

Don't expect better fuel economy than stock.
After all, more power=more fuel. |

Well after the 800 mile weekend excursion, I was getting 23 mpg on the highway....kinda low in my estimation. At 4 bucks a pop for a gallon of 93, it adds up.
It's still a blast to drive, although I really need to get an AFM installed. |

I'm running a 9580/w carbs, and my mpg's suck!

Mine has a 9580 as well (IMG:style_emoticons/default/sad.gif)
Hoping the Carb Clinic on the 25th. helps to get it dialed in. Ordering 32mm venturis and some additional sets of main jets today. I'll report back. |

Be careful if you lean it out at cruise to watch your head temperatures.
I don't have that combo, but I get my coolest temperatures around 13.5:1 at cruise, which yields around 28-30 mpg highway. I could go leaner and get better fuel economy but it's worth it to me to keep the engine cooler / last longer. If this was my only car I might experiment with a leaner cruise, but since it's the "fun car," this compromise is ok. |

" At 4 bucks a pop for a gallon of 93, it adds up. "
I'm running my 2316 with Raby 9560 cam, SDS injection & ignition & A/F/KA/S/Z gearing and can't seem to do better than 8mpg at DE's. At over $8.00 per gallon for 100 unleaded you're right it adds up--like a dollar a mile! And averaging about 60 works out to a dollar a minute.....definitely worth it!

I'll report back. Let me know how it works out. I have a narrow band o2 sensor, but it's useless. I'd invest in a wide-band (I am now) first and maybe a couple cht's (1-per side). Good luck! |

If you've got this arrangement, what are you getting for MPG's? Curious to see how you do. I'm not hep to all of Raby's cams. Is the 9550 a carb cam, or an FI [compatible] cam?It's the famous Webcam #73 + 5deg on exhaust to help keep heads temp down. It's good for both stock FI and carbs, although you can use a cam with more overlap with the carbs. |
