yeah it should def. have a clip to keep the rod from coming off

 

hondan00b: do you know the part number for that spring from mc master?

 

why would you go through all that trouble, and ruin the wastegate???

 

Just a quick question for everyone. Why doesn't anyone ever just slip a light wastegate spring over the actuator rod with a fender washer, compress it, and hold it in place with a rod clamp? If you don't know what a rod clamp is, think --> micro C-clamp. You can make your own with a short piece of tubing or nut that will just barely fit over the flattened of the actuator rod, drill and tap a hole in the side, and insert a set screw. Or just grind a slot in the nut so it slips over the rod from the side and it'll be even easier. All comments are welcome. Please feel free to knock it down if it's a dumb idea.

 

So uh, anyone ever tried anything like this ^^^^? Seems like a cheap easy practical idea to me? Just wondering...

 

why would it mess up the waste gate by putting a spring in it???

 

how are you gonna get the spring in?

thats much cleaner and reversible than cutting the can apart. good idea, it would work great.

 

i can easily get the can apart and the spring in there.i just need to know which one to use...how would you know what pound spring to use with the method right above this w/ the rod clamp?

There are two methods:

1) Major league guesstimation, i.e. trial and error. Exercise CAUTION! Be conservative at first, then up the boost a step at a time.

2) Find out what force (a) it takes to open it right now (fish scale?). The opening force (b) of the diaphram is (boost pressure you want) x (area of the diaphram in square inches). (a) - (b) is the amount of spring tension you will need to add on the outside towards the wastegate for it tp open at the desired psi. Find a spring that has a nearly constant spring tension over 1/2" - 1" travel at the desired force. Hint: ---&gt; a larger OD and/or more turns make it more linear. If you use a spring that is only compressed 1/4" then you will have mad boost creep after the rod moves more than 1/4". I know that will be obvious to most but I thought I'd remind the noobs just in case.

 

sounds like a cool idea... i just don't know if it would be easier for me to switch the internal one rather than trying to guess about the outside method
