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*

Some guys are working on it. They were for the VE that they used in the VW diesels. The spring mount is a little different but guys are working on it. I would love to get my hands on a VW VE pump.

The 5000 RPM VE pumps used plungers half the size as our VE pumps; they went faster but moved a lot less fuel.

who makes our springs 12 valver

RSWORDS · #11 10-22-2008, 06:50 PM

For a 2nd gen 12 valve there are alot of places that can get you a spring. For those of us with 1st gen's you have to pretty much get it from Bosch.

**meclint692002** · #12 10-22-2008, 10:10 PM

I have a question what is the safest rpm to wrap a first gen up to with a factory motor? At what rpm do I need to get new valve springs?

RSWORDS · #13 10-24-2008, 05:04 PM

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.

if u wanna go above 4000 u need a fluidamper to keep harmonic vibrations from becoming catastrophic.
