If you read Kawartha's gear rule closely,you will see the flaw!!!They say you cant be over 5.40 final,and if you run a glide,you must not have a gear no bigger then 2.73,with the 1.82 glide,well that only gives you 4.96,and you must weigh 50lbs heavier.
If you run the 350 or 200r,you must run a gear no bigger then 3.23,with the second gear of 1.52 in the 350 turbo,you have 4.91 final,or with the 200r you have 5.07 final.......all this is not even close to the final gear rule of 5.40...hmmmmm
Psst,ford boy!!How do you know what the 3.08 gear turns???lol Okay,whens the last time you seen any racetrack with a gear rule,verify the trans ratio,we all know there are more, then the 2 comman ones..
2nd last night broke my 273 in practice. Ran the 308 rest of the night...didn't like that much rpm with the 602. Also didn't like all the extra engine brake. Rolled better through the corner the next week with a new set of 273.
2008 season Mosport DQed a thunder for the wrong gear/ other that that never seen gear rule enforced anywhere!
Another 602 eh?? How much did you have to weigh Mr. Fordarama??? ;DAnd isnt the gear rule just for the built engines?
