Quetion about 4efte intake manifold vs 5eFHE asis admission

[Janki]

some body know the diferences between his manifolds of admission ?

trotel body ?

CMF capacity ?

wich one gain more whp ?

 

[Jay]

The ACIS is bigger and has additional flaps that open at a particular RPM to allow more air to flow. Bit of a bugger to get working but should offer performance gains.

Haven't had much personal experience with the ACIS manifold myself but if you search the forum for ACIS plenty of related discussions will appear.

Hope that helps,

Jay

IF you can get it to work it should be very good.

the jamaicans have done a fair bit of work with this iirc, as jay said best thing to do is have a search on google

Its designed to create torque lower down the rev range, it would not create more whp at the top end as the runners are not much shorter than stock then. If its just pure top end power you want, then a custon intake with short runners is your thing.

i am running axis myselve and u get more torque lower down u will only get a few more ponys top end but the torque is bigger its a good manni to get a bigger turbo going its all about the setup

When properly setup and activated at the correct rpm the ACIS manifold give smooth power delivery allowing for both low-mid to high rpm torque. The effect of the long runners accelerating the lower rpm intake airflow also enhances response. This has been dyno proven. A run with long then short runner at the same boost show the correct crossover point where the torque or power curves overlap. It's a worthy upgrade over the stock intake manifold. The throttle body from the 4efte manifold bolts right on. You'll have to drill and tap a hole for the air intake temp sensor and rotate the stock idle control valve to suit the mounting points on the ACIS manifold. It's also worth noting that fitting the ACIS also moves the throttle inlet a couple inches to the right. An extension for the throttle cable is needed and any IC inlet piping modified to suit. I'm also running an ACIS, it was one of the best purchases I've ever made.

you have some picture of you work with the modification of the you ACIS ? and the trotel body of 4efte and the ACIS have the same size ? 60mm?

here u can see my 1 i use the 5efhe iacv and reversed the spring in my axis actuator and used a aircon vsv valve to operate it ( the unit bolted over my chassi nr )
u can also see where i tapped for the ait sensor
i unbolted the pully from tb and made it rotate a bit so i can use 4efte cable

and the 4efte and 5efhe use same size tb 50 mm

how much whp you have?

 

[5e colin]

dont know how much bhp i am running i am running the ct9 atm till i get my acis setup spot on , went on the rollers to check my afr on the pfc fcon thats when i noticed that my acis actuator stays under pressure when i change gears fast so building another vsv system T pieced into the acis line and triggered on my trottle pully when at wot
( at wot the vsv will be closed from T pipe and when releasing the trottle the vsv will open releasing pressure back into the manni )
will be using a door switch on a bracket bolted to the trotlebody as trigger

will reply ere with pics on my progres to give u some ideas

below is the pic i am plummed in now but dont take any notice off the 1 way valve it dont work it dont release air thats why im working on another vsv system ontop of that

ACIS with a SW20 throttle body fitted, I use a shift light controller to switch runners.

Before you ask about whp figures, I changed to this set up at the same time I changed to 5E cams and a front exit exhaust. The car ran the quarter mile consistently 0.5 seconds faster than before, when it was dyno`d, peak power had dropped by 25 bhp.

at least you have plenty of horsepower to play with, many couldnt afford to see 25hp go lol

By the way have that bay looking factory John!

from the inlet and wrapped cooler pipes to that covert alloy radiator down the front.

Looks fantastic.

as said above...acis works great with larger turbos
the way we hook it up here (like newguye's set up) does not require any adjustment to the acis actuator

items needed
fully operational acis manifold and actuator---needs drilling/tapping and fitting stock AIT sensor
1 normally open VSV (it should have 3 ports, 2 "free" and 1 with a samll air filter connected most likely)
some vacuum hose
1 one way valve
1 vacuum canister (a sealed container with 2 ports on it:haha
1 rpm activation device

here's how to install
find a vacuum source/port in the acis intake manifold ---->connect vacuum hose to the source/port and run hose to one end of the 1 way valve (the direction of the flow is VERY important, basically you don't want boost reaching the vacuum canister) -----> connect vacuum hose to the other port/end of the 1 way valve and run/connect vacuum hose to one of the ports on the vacuum canister----> connect vacuum hose to the other port/side of the canister and run/connect hose to one "free" port on normally open VSV----> connect hose to the other "free" port on the VSV and run/connect to the ACIS actuator port

you are basically forming a "looped" system

the VSV will be controlled by the rpm activation device/signal, which will operate the short runners. basically when activated, the VSV will switch to atmosphere and allow the short runners to open. when deactivated, the VSV will keep vacuum in the canister to hold the short runners closed

Disclaimer---all risks are at you. i take no responsibility for any damages


will try to edit it as i find more time...maybe add some pics if newguye has some time

to the 1 way valve ,,,, it dont work ,,,, under boost ,, it doesnt release the pressure keeping the acis actuator closed under pressure

i figured out a way to get rid of it whit the help of dac69er ( supermod ) using a vsv no , and a vsv nc

usung the oem axis vacuum vsv to release the pressure triggered by a door switch at WOT ( closed TB disarms the vsv no to open releasing pressure )

left vsv nc operated by the rpm switch the right vsv no activated by doorswitch at tb at wot

 

[weeJohn]

You fit a 1 way check valve in parallel with the solenoid so the pressure can release from the actuator when boost drops. I found 1 on my car, on the egr system i think.

 

[5e colin]

is it like the picture of the axis diagram i uploaded john ???coz that didnt work with me on the rollers it stayed shut , thats why i had to come up whit the vsvno

 

[gorganl2000]

not sure what problems you are experiencing 5e colin,,,but the 1 way valve works great...all it does on newguye's set up is to allow only vacuum to fill the canister (no boost----boost pressure closes the 1 way valve)

you sure your 1 way valve was hooked up in the right direction or functioning properly or even able to withstand boost pressure ??

 

[5e colin]

""""" you sure your 1 way valve was hooked up in the right direction or functioning properly or even able to withstand boost pressure ?? """"


well my freind that i dont know i think it was the setup becouse it stayed the same when flipping the valve 180% OR mayby my valve wasnt up to the task ???? i dont know

i just ordered a micro switch from ebay in oz 1 that does both no and nc to operate my vsvNO so 1s that arives this setup will work to

my doorswitch idea does not work ha ha when pressed in they loose signal thats the opposite from what i need , had it all bolted to the car and wired up and got a surprise ha ha

I have recently installed the ACIS manifold and following the advice of gorganl2000 and iFur i have used the vacuum canister from an evo which has a one way valve built in and connected directly to intake manifold the other end goes to a NA 3 port solenoid which then runs into the diaphragm. One wire of the solenoid goes to ignition and one wire to a gpio output on my AEM EMS4. I set the AEM to activate the gpio at 1300 rpm and tested. Then 3300 and tested. Now I have it at 5500rpm. The one way valve stops boost from reaching the canister and allows it to be only filled when car is in vacuum.


Vaccum canister and solenoid and no I dont run an idle control valve.

Wires before tidying up.

One of the pink wires runs to the solenoid

Had to use a bicycle brake cable as an extention for the throttle.

I am running pretty low compression stock pistons in 5e and this manifold has down bottom feel so lively. Car feels light.

[5e colin]

nice 1 lad for getting it to work under vacuum works wel in the vid

i finished my 1 to but for boost aplication i ended up using a microswitch on the tb for my vsv no






this is the diagram so you get the idea



its working perfect now releasing the pressure the second i release my pedal a few mm im happy with it just neads to be tidied up a bit
