does anyone else have cam problems? i broke another cam today that makes the thrid. the right side of the intake value everytime. does pami make better cams than RWR?

 

DSmike you might check the clearence on that side. Also make sure that spring is sitting down perfect.

 

i check all of that stuff GOOD before i put it back together. i broke 2 cams with the stock springs and this is the frist with the woods springs. how can you tell if the spring is setted good?

 

Are you slamming a valve into the piston? Overreving?

 

more than likly, i was racing a drag banshee and missed a gear. but wonder why it don't bend a value? i know i'm not the only one that misses gears or am i?

 

DSmike,
Maybe you need stronger springs? Steel cams?
I have missed gears too[img]i/expressions/face-icon-small-blush.gif[/img] ......but it has never caused any problems except.....I spun a timing gear,broke a cam,broke a titanium retainer which dropped the valve into the cylinder...and blew a tranny
All 4 items happened at different times non related to each other.

Anybody make a CDI with a programable rev limiter?
What happened to the rumored MSD box?
I curse my rev limiter but maybe not so loudly anymore.

 

What is your piston to valve clearance with those cams? How are you measuring? If your using a dial indicator it probably isn't the most accurate way. I'd try using clay. That way you can measure around the eyebrow of the valve cut in the piston. Usually it is recommended to have .100" of clearance on the intake valve and .080" on the exhaust side. If you have that and your spring pressures are still in spec, then your spinning it too high. You will need a CDI with a rev limiter to keep you from going over 9000, 9500 rpm.

 

ROCKEY,

i used clay to messure the clearance. i can't tell all my secrects to the motor or i would tell you what the piston to value clearance was.


JEFF,


how long would it take to get pami cams?

 

AHH yes the secrets to making a stock bore DS as fast as a 760! We all want to know!
