Thread: What RPM does your VVL activate at?

The last car I played with a month ago gained 6whp from activating at 5000 to 5400 during tuning on a dyno jet using Nismotronic. (Single activation) It had a N1 Cam and 3inch exhaust with megan header.

Have mine both activating at 5000. I used to have problems when I had them set at 5500 with falling off vvl between shifts from time to time. Ever since o switched it to 5k , its been great. I will have to experiment on my other b13 when its done since that one is turbo (vvl+t) to see what rpm point is best and to see if I can benefit from individual activation.

your probably going to get mixed votes between stock and n1 cams. for n1 cams, 5000 +or- a little for both seems to be the most popular with stock internals and normal bolt ons. i did a lot of searching and asking, and talked with Greg V about it when he came to seattle.

my car likes 4900 for the cam switch point.

Its a stock motor with bolt ons

6k switch point, i also go on temps above 150*F and over 60 TP load in the NEMU. 2.1L VE, 12.5:1 comp, and N1s.

How is your acceleration at around 5500RPM?

Better than it was before the dyno and i did not change any fuel settings down low, just cam switching. No dip in power until after peak. The dyno graph is smooth all the way up.

6k both cams here too, it bogs down if set bellow that.

Kelford 184c cams, stock bottom

n1's@ 5800in/6100ex. 12.5 cr/87mm bore. using a pair of 8969's.
seems to work pretty good for me.

6.5k for both of them, could do with raising them, but having issues at the moment...

that is N1s, in a N1
