VICS Sucks!!!!

[BlkZoomZoom]

I know I couldve used this info a month ago...I was a hurting man for traction lol.

I did a booboo last night too...I put too long of a bolt into the oil pickup tube support. When I started the car for the first time with this motor it was making a horrible ticking sound from the bottom end. It took me like 1/2 hr to realize what was making the noise. The bolt was touching the rod end as it went around. lol

So what would happen if you left them open all the time? Would you notice more low to mid range power or loose it?

good question Tim I am interested in the answer of this as well, I have been debating if I should remove mine or not

The graph that is higher that I posted... that is with them open from start to finish... you can see where on the low end it's a tiny tiny bit lower... but not much.

EDIT: Only shows a small "apparent" loss between 4200 and 5200 rpm's... may be boost related though instead of VICS, but also COULD be the VICS being open that caused that loss instead of the butterflies being closed until 5200 like stock.

You got it backwards buddy, they open at 5200, not close.

That's what i thought....

That's what Terry figured out a few years back on his dyno runs.

Any link for that?

So if I just unhook the vacuum line to the solenoid and plug that line so there's no leak, that should do it? I may try this the next time I dyno if it's that easy.

Yep... it is that easy.

vics?

Variable Intake Control System. At low RPM the air goes through long runners for more torque, at high rpm the butterfly's switch so the engine breathes through short runners for more top end hp.

close, but alittle off.

Variable Inertia Charger.

No short or long runners here, just plenum sizes and such.

 

[Mallard]

Are you sure it's plenum sizes? You've had yours off the car so I assume you know what you're talking about, but my friend and I just talked about this last weekend. The casting looks nearly identical in shape to his Eclipse dual runner manifold. We didn't take it off the car though.

Do you have any pics of the inside?

 

[TurfBurn]

yeah.. no dual runners.. the butterflies switch whether or not a dead end plenum is used or not...

 

[Kooldino]

Nah, he just told me on the phone back in the old spool days.

 

[Kooldino]

VICS is Variable Intake Control System last I checked. It's also just an extra plenum...it's just another chamber that opens up.

 

[Lord_Zath]

subscribin for the answer to the universal question of butterflies, air, and runners

Nope Dana .

 

[Kooldino]

Doh, I mixed up VTCS and VICS.

VTCS = Variable TUMBLE Control system....and I just replaced the T with an I (intake)

 

[duMb KeoLa]

so what if we just remove the butterflies in the intake manifold like we did with the vtcs... would that work as well??? hope you can answer this soon as i am doing my intake manifold today... also, would it help if we port/grind out where the vics originally is? i mean... less manifold = more flow right???
