In all reality all you need is the 3200 spring. Teh VE does not make any real power over that. Anything over that and you should look at 60# Valve springs. And I would not spin the stock internals more then 4k.

Here are the part numbers and different rpm defuel specs for some springs.... there are alot more. You can even get a spring to fuel up to 5200 rpm.
1-464-650-386 spring = 2800rpm spring *Stock*
1-464-650-366 spring = 3200rpm spring *Best Over All Mod*
1-464-650-374 spring = 3800rpm spring *May need to trim to Stock Length*need 60 lbs valve springs*
1-464-650-354 srping = 4200rpm spring *May need to trim to Stock Length*need 60 lbs valve springs*

I'm in the process of making a mechanical TDI pump for a VW TDI. I'll use parts from the stock electronic VW TDI pump, a mechanical VW pump, and a 4BT pump. I'm interested in finding a 5200rpm spring, also do they have ones that go higher? Could i use the those partnumbers and contact bosch to order springs?

I might also note that a few overseas guys have more available mechanical pumps. Several have installed 12mm plungers and had them sieze from high rpm high fueling conditions. Might be something to think about for you guys.
