Progressive Nitrous Controllers And Crank Durability

I had read several years back that the latest wave of progressive nitrous controllers were going to change the face of nitrous in every bracket for which they are ran.
One of the key benefits of the system was the perceived 'gentleness' of a progressive system on crankshaft, main (and bearing) durability. The logic was this; the crank would flex much less going 50-100-200-300 over a course of a second than a an instant 300hp hit.

Was there any validity in this perception?

Thanks

tuneup is gonna make more difference

Like Jon said, crankshaft durability is a matter of tuneup more than anything.  That and using good parts to begin with.

We have customers with up to 64's in the foggers and even with the progressive they are all in by .4-.5 into the run.  So I don't see that making much difference.

And there is not a solenoid out there except from England that will pulse slow enough to turn a 300 shot into a 50. From our dyno test you are lucky to cut power by a third of the kits value.

Wouldn't ramping an MSD box be a better idea (and easier on the 'noids) than using a progressive/pulse anyway?

we do both. Never had an issue pulsing system.

Could you explain ramping the msd?  Are you just talking about ramping timing in to control power?  Sorry for the dumb question.

Yes. We run crazy timing maps to control power. Especially with the radials most of our guys run.
