68Datsun510 Posted June 19, 2013 Report Share Posted June 19, 2013 Hey all, just curious about the average mileage you all get, specifically dual carb setups.Mikuni, Weber, SU With gas at $4+ a gallon everyone is more conscious of mileage... Post engine size/carbs/MPG??? Quote Link to comment

metalmonkey47 Posted June 19, 2013 Report Share Posted June 19, 2013 My L20B W/ Weber, header, and L16 intake did about 29mpg. Haven't measured my LZ yet, but I'm gonna guess I'll do about 18-20. Quote Link to comment

Tristin Posted June 19, 2013 Report Share Posted June 19, 2013 I got 39.xxx in my stock Sunny pickup powered by an A12 on the way back from Canby. Maybe I should do an A-series swap in my Dime. I bet it would really scoot. Quote Link to comment
q-tip Posted June 19, 2013 Report Share Posted June 19, 2013 76 kc 620 L20b automatic with stock gears. Emissions removed and a weber on top. I get 18mpg average, which is shit. 72 4dr 510 ka24de 5 speed 3.70 gears, about 25mpg average Quote Link to comment
Dguy210 Posted June 19, 2013 Report Share Posted June 19, 2013 Maybe I should do an A-series swap in my Dime. I bet it would really scoot. B210 crossmember and it'll bolt right in. I've wanted to do one of these just for the lulz. Quote Link to comment
datzenmike Posted June 19, 2013 Report Share Posted June 19, 2013 76 kc 620 L20b automatic with stock gears. Emissions removed and a weber on top. I get 18mpg average, which is shit. 72 4dr 510 ka24de 5 speed 3.70 gears, about 25mpg average . Depends on driving style and trip length. I would expect above 25 on trips. 18 seems low.

Im sure my 4dr. would be slow as balls though... slower than it already is. Would be interesting though. Quote Link to comment
Ratwagon1600 Posted June 20, 2013 Report Share Posted June 20, 2013 With gas at $4+ a gallon everyone is more conscious of mileage... Ouch, just did a quick conversion. Based on our current price structure, we'd be paying $5.67 a Gallon! Quote Link to comment

datzenmike Posted June 20, 2013 Report Share Posted June 20, 2013 Gas today near me was $1.30 a liter. @ 4.546 L per Imperial gallon that's just about $5.91 a Canadian gallon. Quote Link to comment
