couldnt help myself, got the book out and its a 3800rpm spring. Still want the p/n though?

 

YES PLEASE.

 

Of course we do...

I think a Cummins could take 4000 RPM for a minute or so, right?

 

cummins 5.9 marine engines will turn 4200rpm all day long

 

Ummmm.......guys, you might want to reconsider the usefulness of such a high RPM rating on the spring(s) you're considering...
Our engines are NOT set up to run beyond 3400'ish RPM on a regular basis....
You "can" run them higher on an occasional basis but you are strongly advised to install the heavier 60# valve springs to start with and to also make sure you valve set is DEAD on or you'll have some rather unpleasant surprises in short order.
Yes, you can "survive" a run up high in the RPM band but that is a "survival" event NOT a "safe and often done" event catagory.
In addition, you are also pushing that VE WELL over it's design limits and it WILL end up costing you some $$$$ to learn the lesson eventually...

pb....

Isnt the ve used in bmw's and vw's with a 5000+ rpm application?
