O.K. so i built this big four banger. a 2.4 l,big bore four. all the goodies,rad cam,big valves,dual springs,103mm pistons on stock stroke rods.lightened flywheel and 44idf webers. the engine wouldn't run on the 50 mains, but the 60's seemed to make it screem. and screems it does! great low end tork and the top end comes up fast.
the engine is great, but the mileage sucks. i put 8 gals for a day at the race track.usually plenty for the drive up and back, two drivers with fun runs. so hear it is, low on fuel at 100 miles! less than 10 to the gal,more like 8 something. do i have a issue going on? the engine seems to run like a raped ape,but i expected a bit more on the mileage dept. any ideas? |

+, must be 100miles round trip just driving to bremerton and back. they run quite long courses at bremerton, with lots of 2nd gear. 2 drivers=6 passes (minimum) + fun runs. wide, sticky ax tires. long line ups and idling if you don't shut it down. a bit of stop and go from your place to I-5. it adds up. not surprising that the milage seems low.
