The Mega Supercharger 4AGZE thread, using twinscrew charger

[nick.parker]

Nice result. Certainly proves the efficiency of the twinscrew over the stock unit.
My car (4AGZE) made 150rwhp with SC14, cams, water to air intercooler, bigger throttle and piping and about 14psi! It now runs 18psi, but havent dynoed it. Why didn't you give it more herbs for the low rpm part of the dyno? AFR lean?

Wow, I thought I was going to be the first to dedicated twin-screw an AW11! I'd definitely be interested in the brackets/tensioner/blower, but I can fabricate the rest (intake manifold, W2A in the boot, etc) and are planning on running a different TB.
I'm definitely looking forward to some pictures my friend!

Thanks.
We have not experienced any lean conditions below 3500 rpm, just up top and more then likely a result of maxing out the stock injectors. We will be swapping in 440's and bigger afm in hopes to gain more hp at the current boost level. Just to note, the bigger blower is spinning quite slow to attain these power levels.

We are using the stock intake manifold and will sell the kit in a fasion that most will fab their own intercooler piping. Here is what is included in our 4agze kit:

2 Stage bracket, Solid Billet Aluminum S/C Inlet Manifold, Billet Aluminum two peice outlet (able to turn 180 degrees if desired), Billet fuel pressure regulator relocation mount, Billet tps adapter to throttle body mount (allows us to use stock 4agze tps on massive throttle body), Billet bypass valve (attaches to inlet and outlet pipe), Massive throttle body, Billet throttle linkage bracket (connects throttle cable to throttle body on Aw11), breather/filter for twinscrew, Billet 2 peice support bracket (mounts inlet to manifold for additional support), spring loaded tensioner, belt, hose and clamps. 1.33L or 1.7L Twinscrew supercharger and pulley.

Optional Parts:
Remote IAC relocation plate (Allows one to use stock IAC), A2W Intercooler for Aw11. 6 rib water pump and crank pulley for max boost without slippage, Intercooler piping for Aw11 stock intercooler or A2W. Smaller S/C pulleys for More Boost.

Power levels with the two blowers will range from 160whp to 500+whp so long your engine can handle the boost!

Do you have pictures?

[johan_oern]

Do I need that IAC relocation plate or can I safely ignore the IAC altogether?

It is fine to run without it as I have done so, but I do like using it as it makes the idle more stable on cold starts and stop and go.

I think it is safe to say that the twinscrew s/c if far more efficient then the stock blower. All we did was use a bigger filter and removed it from the engine bay. We also added water injection at 6k rpm to help the lean condition we where having up top. Still using stock injectors, stock afm, and stock 2 inch intercooler. Blower is still spinning slow and not working hard at all which means alot more power to come!!

RonRob, I'd sujest doing some pre throttle body pressure measuring. The standard AFM is stupid small and a stock 4AGZE will have it max out early.

[TERRA Operative]

Imagine it on a MAP 4AGZE......



My rebuild is inching closer, which will include a new charger..

[RonRob]

Not sure how to do the test you speak of but I will say that map based Ze's will surely benefit, but first must combat the 5500 power dip that is nearly impossible to figure out exactly. Guess you can pick your poison. I must say the since I am able to power to redline with the stock efi intact, my choice goes to afm. Looking at one of those translators the Supras use with so much success to get rid of the afm and replace it with a Maf.

Here is the Ae86 Twinscrew inlet design. Of course I will refine it and countour the shape like the one for the Aw11/92/101. But this gives an idea of how the tb will mount. From here most can use their stock Intakes which saves from making a new one.

Not sure how to do the test you speak of

Simply plumb a water manometer or a sensative pressure gauge that has a maximum deflection of 1-1.5psi in between the AFM and the throttle body. Then drive it flat out and see how much pressure drop you get between the AFM and the TB

I'm using an E-Manage Ultimate on my twincharged AW11. I currently use it to fix the output of the bigger AFM (SW20 turbo size body, but it's actually from a 2.2ltr turbo Mazda with the 4AGZE circuitry).
It can be used to provide a false AFM signal, so can the AEM fuel/ignition controler.

The fun part about the Toyota flap type AFMs s that they use a dropping voltage to sho an increase in air flow. I've not heard of any MAF meter that work like that.

At this point and time there is no need to do a pressure test on the afm. Its too small to give me the S/c Ve I need when I start to spin the blower faster. The afm is only good for my needs till about 175-190rwhp. After that the Ve of the s/c begins to suffer and is begging me to get rid of the afm. There are a few translators out there that can not only convert afm to Maf, but can also reverse scale to make the ecu think its seeing 5-0v. I don't want to endorse any piggybacks until I give one a try. A bigger afm would work better, however there is no afm big enough to support the Twinscrews Tb which means any afm used will become a bottle neck.

how much further away are we now from the development of a saleable kit?
