When using the el cheapo boost controller made from a ball bearing, spring, and brass fittings screwed together, do you need to poke a small hole in the line from the boost controller to the wastegate to relieve the pressure once the controller closes?

 

FYI: My slightly more than $5 Hallman BC does...

 

i have heard of boost spikes with this set up when the spring gets hot

just FYI

 

I would think that as the spring gets hot the spring rate would go down and the wastegate would open sooner since the modulus of the spring steel decreases with increasing temperature.

 

well like i said that is what i heard. or maybe the spring rate (as you said) would go down so much that is would block the signal to the wg. not sure, but that is what i heard throught the grape vine
