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

Thanks.

At 52 hours TT on engine with passenger; 80-90 mph hiway and 120 miles city driving. Total miles 996 miles. Got 37 mpg.

Is that with carbs or F/I ?

Ljet. She ran great this past weekend, 400 miles each way. I'm just not thrilled with my uh, fuel economy....

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.

I have to fix my ODO and the the A/F dialed in so I can find out ...

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.

sounds like it running to rich.

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

Mine has a 9580 as well

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!

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!

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.
