I have 12&1/2 to piston,web cams,valves and springs, and head work.I run honda radiles most of the time, What is the best gearing you guys have found for 300ft drags.

 

I have a raptor and the best gearing for 300ft (100yards) for me is 14-40. I take out in 1st and 3rd is right at the top of the power at 300ft. It runs 52-53mph in 300 feet in 3rd. Hope that helps you some. The raptor runs 5.7


I also race a 250R big bore (350) on alcohol. I run a 15-36 gearing take out in 1st and go through the end in 4th at 63 mph running 4.7 seconds.

Usually the quicker the revs the faster it accelerates so i would try stock gearing to begine with. From there you should be able to tell if it runs out of gear to fast then go larger on the front sprocket.

 

Which is best up or down?

 

i am running a 14/43 with 22" tires. i leave in 2nd and not for sure what gear its in at the end i think 5th.

 

Where are you geting your 43 rear from im haveing problems finding that combo i buy all my setups from sproket specialist and they don't make the 43 im bummed!

one more thing the regular aluminum lasted me about half a year it was 52.00.So i would suggest buying there harden anodiezed one it will last twice as long for only 10 bucks more!

 

WOW ill try again last time i ordered i told them one of evey sproket they make in the titan tough series and alls i got was 40,41,42,15,16,17, but ill try again.any other sugestions?

 

i get all of my stuff from ron woods racing.

 

Can you get away with running a 15/43 combo without adding links? I know you can run a 15/42 combo fine.
