ACIS Info (good stuff) (Moved over from alf's 'Darth Vader' thread)



green/blue is the longer torquey runners
red/blue are the short runners

the short runners are useless till higher RPM as you can clearly see here

yes that is a 45 hp and 60 ft lb of tq difference between the two

look at the area under the curve alf see what boostjunkie has been missing

i can point to a thread where he states that you should run them open all the time and loose all that torque under the curve

then go a step further and realize that the manifold he made for his car was compared to an ACIS manifold that had the butterflies removed and against that one it lost 50 whp and 50 wheel torque in the meat of the powerband


so had he compared that shiny useless intake mani of his to a functional ACIS manifold it would have been an even greater loss

seeenow? you would have paid 600 dollars for a manifold that would lose you like 100 hp and torque!!!!!!!!

i hope you do not become oblivious to obvious knowledge as he seemed to become

please realize i only want to see you go faster

So that 50 hp and tq loss he had was compared to that of an ACIS manifold with the butterflies removed? WOW....and all this time I thought it was against the ACIS manifold hooked up properly. So on a average then, we are talking close to 100 hp and 100 ft.lbs lost in the lower rpm band up to around 5500rpm? Thats insane........................

and i quote from the useless intake manifold thread

Quote: Originally posted by GT_REVVA  
that :censored: is frickin BEAUTIFUL Denys! definitely a show/magazine worthy piece - and you gained 20 more peak hp in the high rpm range.

let's talk tech though: sleepyrz analysis of the dyno graph was spot on - the FHE intake outperforms your new intake throughout the power band up to 6800 rpms - in both hp and tq, peak and width. you actually lost about 50 hp at 5500 rpms and, at 7800 rpms, both manifolds make the same power. so, in all, you made ~20 more hp in the last ~700 rpms and, you made less peak tq .:deal:

don't you think you could have gotten the same or better performance from an FHE manifold with a 70mm throttle body in place of the 60mm Nissan body you had.:dunno:


now i need you to read that last sentence again and realize we told him this before he went and made that manifold

trevor is just nicer than i am and is saying "see! i told you so" in his own way

In this diagram:



I'm not quite clear as to the use of the 3 way solinoid/valve...

Does the line which comes from the brake booster with the
"one way valve" (check valve?) feed one of the 3 legs of the 3 way
solinoid valve... and if so, do the other two legs controll the
opening/closing of the ACIS's butterflies when the RPM reaches its
target?

OR...

Does the line from the brake booster go to the intake manifold's
plenum by way of the "one way" (check valve?)

Also what would be really helpful would be a parts list, where to
source the part, part # etc. for both the 3 way solinoid and a relay,
as I've read the signal (voltage) coming from the RPM moduale is
not enough to controll the solinoid.

Is a vacumm canister (something I've read about) also needed and if
so, where would it go and how would it be connected?

alf :dunno:

PS: ...and FINALLY: What's with the 'leg' of the 3 way solinoid which
PS: goes to the air filter?

ok, here's my interpretation of that diagram (bear with me, i dont have the wicked photoshop skillz so, hopefully my verbal interpretation can create some kind of visual and NOT cause confusion in the process:doh:)

ok, plumbing the 3 way valve into the brake booster line eliminates the need for a vacuum canister.

see, the brake booster line acts as the vacuum canister because the one way valve (in the booster line) is open in vacuum but closed in the absence of vacuum/presence of boost (thereby storing vacuum in the booster). confused yet? no? ok...:lachen:

now, the line from the 3 way valve with the check valve on it uses the vacuum from the brake booster line to keep the actuator closed. the check valve (on the 3 way valve) keeps the air from flowing back out of the actuator until the rpm switch is used to open the 'leg' with the air filter on it at which time the air stored in the actuator flows out of the 'air filter leg', thereby opening the actuator at the desired rpm.

i damn near confused myself writing that crap :dunce:...if my computer wasnt shiat, i'd try to work some photoshop magic but, i'm pretty sure this thing would just freeze up.:lachen:

hope that helps or maybe an interpreter could jump in here and translate further...i mean i get it but, i think my explanation maybe still a bit too technical to be useful.:lachen:

I think the confusion with that diagram comes into play when you try to think about where the system is getting vacuum to begin with....

I understand your explanation completely, and can get you something from paint, but like I said, I am confused as to where that system gets vacuum to begin with. I know right now the brake booster is hooked up to the manifold and thus draws vacuum, but in that picture, there is no original source. :dunno::dunno::dunno: maybe I am talking out my butt though

I am assuming that the brake booster creates enough constant vacuum to open the butterflies?

What type of switch (green area) is openned by the RPM (window) switch.

the brake booster is a vacuum reservoir

it holds vacuum in it because there is a one way check valve so the vacuum doesnt get filled by the atmosphere it gets stored


the brake booster gets its vacuum suppply from the engine when it is at idle

at idle the motor pulls approx 20mmHg of vacuum which gets stored in the brake booster again due to the check valve


now when the solenoid is opened or closed by the rpm switch this allows the vacuum stored in the brake booster to act on the ACIS actuator

when the rpm switch deactivates this closes or opens the solenoid and this allows the atmosphere from the small filter (no vacuum) to act on the ACIS actuator


now here comes the part that may be confusing you

that air filter is NOT THE AIR FILTER FOR YOUR MOTOR

that is a separate air filter so stuffdoesnt get in the lines and stop the solenoid from opening/closing

its one of these

By the way, that diagram is not my creation but, was taken
from HERE <- clicky!

More stuff HERE <- clicky!

By the way, because of the excessive Mid-Atlantic heat
wave, TERCEL1 was not tuned this past Friday/Saturday
but, is expected to be tuned either tomorrow (07-25) or
Tuesday (07-26)... at THAT time, it will be tuned with the
buuterflies closed and then with the butterflies open...
a strategy will then be devised for to take advantage of the
ACIS manifold...

While I realize the dyno-graph floating around show a nearly
50HP gain with the 3 way solinoid etc.... can THAT HP gain be
expected in ALL applications?

I think that I finally understand how to make this work but:

"now when the solenoid is opened or closed by the rpm switch this allows the vacuum stored in the brake booster to act on the ACIS actuator"

I need to know where to get this solenoid.

This says that it is normally closed but opens with the switch.
