Intake Manifold VRIS points

[SuperK]

I didn't see this in the faq or when I did a search, so if someone posted this up, I'm incredibly not sorry but woops anyways:

Not sure if the K8 is correct, since it's got two more than usual:


K8:
RPM:
0000-1900 #1 Closed, #2 Closed
1900-2600 #1 Open, #2 Open
2600-3900 #1 Closed, #2 Closed
3900-4700 #1 Open, #2 Closed
4700-6300 #1 Open, #2 Open


KL-DE:
RPM:
0000-3250 # 1 Closed, # 2 Closed
3250-4250 # 1 Open, # 2 Closed
4250-6250 # 1 Open, # 2 Open


Curve Neck:
RPM:
0000-3750 # 1 Closed, # 2 Closed
3750-4250 # 1 Open, # 2 Closed
4250-6200 # 1 Open, # 2 Open



Long Neck ZE:
RPM:
0000-4062 # 1 Closed, # 2 Closed

KLG4


RPM....0-3750....3750-4250....4250-6250....6250-7500
1..........X...............O................O..... ............X
2..........X...............X.................O.... .............X

#2 is the big one in the middle
X -> closed
O -> open

Are those numbers correct? As far as I knew nothing happened until like 4250 when #1 opens. Blow my lips off.

I'll look for my dyno papers. The VRIS points were set that way, by reading the dyno peaks in the various open/ closed positions, and setting accordingly..

Any information for B6DE?

[Josh]

Why does the klg4 close back up at 6250? I would think that it would remain open until redline

The VRIS tubes aren't designed to flow, they're designed to resonante.

B6DE will be in the manuals.
