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? |

Triaddave... did you forget you have a 5th gear? (IMG:http://www.914world.com/bbs2/html/emoticons/lol2.gif)
I can believe that low of mileage on a 2.4... Do you drive it in the high RPMs all the time? With the 44s open all the way, you really can flow a lot of air/fuel through there. If you keep it at 3000 - 3400 rpms when crusing you should see a lot better mileage. Your motor sounds hot... I need new undies. |
