Capone Posted February 25, 2005 Report Share Posted February 25, 2005 I'm running coolhead 18cc domes (180psi) compression on a stock crank with new seals & bearings. Obviously its not going to hold up, I'm planning on a weekend of a complete teardown, powder coating, and i want to replace the crank to something stronger, or i'm going to have to switch domes. I really like to drag, and the bike feels insane with the power its got now. I would rather switch crank than domes.. How would the hotrod's crank do? Or should I just have the stockie trued & welded? Thanks. Quote Link to comment Share on other sites More sharing options...
Blacksmith Posted February 25, 2005 Report Share Posted February 25, 2005 If you can handle the hit in the wallet, I would go with the HotRods, but if not just have the stocker welded. Any good shop should be able to do it for you. Quote Link to comment Share on other sites More sharing options...
PUSH THE THROTTLE Posted February 25, 2005 Report Share Posted February 25, 2005 Just be careful that if you send yours out for a true and weld they don Quote Link to comment Share on other sites More sharing options...
Capone Posted February 25, 2005 Author Report Share Posted February 25, 2005 how long you think I got on the stocker now? Quote Link to comment Share on other sites More sharing options...
PUSH THE THROTTLE Posted February 25, 2005 Report Share Posted February 25, 2005 From what I've read it could last forever or fail tomorrow just the same. STCLARK was running a stock crank with 180psi and had no problems for quite awhile and only switched because he went to a stroker motor.

richwuest Posted February 25, 2005 Report Share Posted February 25, 2005 A friend of mine went about 8 or 9 years on a stock crank (not even welded) with about 165psi and ported runing pump gas (dyno at 60 HP). It started running bad as the bearings began to get too much play in them, but the motor never grenaded. I have heard of others that did not last near that long though, so you just really never know.

Bansheeman1121 Posted February 25, 2005 Report Share Posted February 25, 2005 My crank went with me only running 20cc domes, the bearing came loose and it was over, those stock cranks are a joke before you risk your pistons and domes put a new one in it Quote Link to comment Share on other sites More sharing options...

Capone Posted March 2, 2005 Author Report Share Posted March 2, 2005 bump. I've been reading about crank pressure, and how much it can handle. As I stated above, I believe my crank is pretty much at the end of its potential, and I'm looking for an upgrade.. since I'm going to bump timing soon. I found some hot rod connecting rods, for 80$ a piece; http://www.pro-flo.com/proflo_wiseco_hot_rods.htm If I replace stock rods with these, then have the crank welded, will it be bullet proof? Thanks.. Quote Link to comment Share on other sites More sharing options...
