Wich ones are stronger the ron woods are rated to perform up to 9,500rpm but what are the pami spring's rated at???

And is there any other company's that make some and what are they rated at?

 

there is web but no info on there springs

 

Our springs are good to much more than 9500, but we don't recommend running the engine any higher than that.

 

Where can i get the pami's?

 

I'm not in business any more, so I have nothing to gain or lose, but I would like to offer this objective, honest opinion.

Team Pami uses a spring that is designed to work entirely differently than the RWR spring. It uses a thinner bottom "washer" that allows use of higher lift cams with less risk of coil bind. This also allows lower seat preasures while maintaining equal or higher preasures at full lift. The advantage of that is the fact that it will not be as hard on your valves. Valve float is prevented at lift, but lower seat preasures will keep the valves from "tuliping" and causing the need for replacement.

Just my honest opinion. I haves several sets of RWR valve springs sitting around my shop, so I've had plenty of chances to check them out compaired to Team Pami spings.

In complete fairness, I'm not going to compair preasures due to the fact that all of the RWR springs that I have are used. All springs will lose force as they are used and there is no fair way to compair used springs. When you are compairing one spring to another, use preasure, not RPM rating. As Elliot stated, RPM is a factor of the whole motor, not just the valve springs. The same springs, in the same motor, with cams of the same lift, could be used up to different RPM based on the "ramp" of the cam.

 

You can get the Pami ones from Gary at TVI or directly from Team Pami

 

Can you give me a phone# for tvi or a website,thanks.
