Valve stem seals

Was wondering if anybody knows a company that makes valve stem seals that will be held by the bottom of the valve spring... As mentioned and pictured in the link below: http://www.skf.com/files/867381.pdf Looking for this type seals for a Pro Mod application. Any help would be greatly appreciated!! ...

Then they would be able to do a good job... The above mentioned link... http://www.unimeasure.com/jx.htm are the wire ones. The ones i am warning for... Especially if you are orientating yourself in data acquisition, you should shop around, but certainly be on the look out to get the right sensors, ...

Yes, i use the liniar sensors even on our roadracing motorcycles to get more accuracy... Have had experience with the wire ones, and they just don't seem to "see" the acceleration... Especially as i explained, the wire ones seem to slacken on dragrace cars, just due to the speed in the ext...

Please steer clear of these kind of measuring devices and check-out the Racepak liniar sensor. I'll tell you why..... the precision this sort of device is not good enough for dragracing. Since the spring in the sensor determines the maximum acceleration the sensor can "see". During the fir...

Okay, that being said, i gather he means that from all the input channels it puts together 12 datapoints per second. But can actually handle and show you 1000 samples/second on for instance one channel... Let me put it this way... 12 samples per second, is 1 sample per 0.08 sec. So in actual fact yo...

To seriously SEE anything concerning dragrace shocks, you need a data logger, capable of doing at least 100 samples/second... I know the LM-1 is introduced as 44 minutes worth of data at 12 samples/second... But can you crank it up to more samples per second and less data time??? Cause you really ne...

Racepak(now MSD brand), has some really good, precise liniar travel sensor in different strokes.

Also race-technology.co.uk sells real good tested and proven liniar sensors.

What is the framerate of your datalogger???

I've dug into the formula, and ran into something interesting... First of all i didn't realize removing a coil has such an inlfuence on spring rate. Done several calculations, with different EM's and so on. Only to realize that whatever material your spring is made of. Removing an x amount of coils ...

The spring rate doesn't really change, when removing a coil from a liniar spring. It is a determined and set specification for a certain spring. Removing a coil, will only affect the free height(uninstalled height) and the ride height. So if you want to alter your spring rate, you will have to acqui...
