Intake manifold questions

If you do, I'll want one.

You could just hook up the VICS solenoid to a regular switch, but that would be a PITA when driving to use. The real trick would be to get it kicking in @ 0PSI at perfect no vacum. if you could do that you would be guarunteed to make more power.
A turbo is load based. so you would have to use a pressure switch of some sort that would turn the solenoid on @ 0 vacum. it can be done. Id love to see someone do it.

I'd love to see your GF naked, but everyone has already see that.... Her nasty messed up trunk area esspecially.... eew yucky

That's what I thought too, but wouldn't you reach 0 PSI at about the same RPM every time?

You do not. Those variables are quite independent. You could use either the RPM or the boost (using a Hobbs pressure switch) or both to trigger the solenoid depending on how you set things up

I would think it would be better to have both. Have a preset RPM so incase you for some reason aren't seeing boost by a certain RPM, it opens anyway. Just my thought process.

TO make it easier I would just do it so it opens around 3000. By then you are done with torque anyways

I would want to force it open by then if it hasn't sensed boost for sure.

If you quit making torque @ 3k or your torque peak is @ 3k then you need to do something different about how your motor is running.

No I mean if you look at it, by 3000rpm in any gear you pretty much have all your stuff moving, so above that is when HP is important rathar than Torque.

probe/mx6 guys use a 'window switch' to control their VRIS, im sure you can use something like that and just hook it up to open VICS at WOT.

because if you're not driving spirited you're obviously trying to save gas, so there wouldnt be any benefit of having the VICS activated at a certain RPM.

personally, i'd keeps VICS and add a window switch, or splice your TPS so when you reach WOT your VICS opens to let more air in etc...

just my 2 cents, i dont know a lot about FI, but i can try, right

MSD sells an RPM activated switch. Wire it with a boost activated switch and you have the two conditions needed to activate VICS.

That could be a solution...

[Lex]

the way a turbo motor revs under boost (or even an NA one) you'd have a very hard time hitting a switch as it climbs through the rpms

[FE3-323]

just get a pressure switch & set it for whatever you deem. that would be your fix there. im sure you could do it for under $25.
