960/90 cam timing revisited S90-V90

Hi Poolman
Looks like we are using the same cam setting. I have to agree I really like both cams advanced. I'll play with it some more, try to dial in a little more advance and see what happends.
Im not sure if this link applies to our engine exactly but it is interesting none the less.

Cam timing simulations

I've had my airbox modified for over a year now. I removed the whole Y shaped mechanism where the cold and hot air meet at the air flap and replaced it with a 3" wide heater duct from in front of the grill all the way to the air box.

My airbox

The 960 intake is very restrictive in stock form in order to reduce intake roar. With this intake passers by definitely notice when I blip the throttle and power is up throughout the rev range. The heater duct is flexible so I've had it pointed forward to meet the oncoming air and to the side. Aiming it forward (pseudo ram air style) returns more kick on the freeway at the expense of more dirt and rocks in the airbox. After the novelty wore off, I turned the neck behind the grill sideways.
I ran a draft tube for about 6 months. I liked how it kept my TB clean but on the down side I could smell the fumes when sitting at the lights. And they are not exactly health. Every time I stopped the car I would have to turn the AC to recirculate. I used an in line fuel filter in the draft tube to prevent any dirt from getting into the crank case. But after a few months I returned it to its stock form. Next time I will experiment with connecting it directily to the intake manafold through a PCV valve.
