i gotta back kawa up. seen this on a nonturbo wrx before.

was tits.

The throttle bodys are normally partially open so at low RPM it is feasable!

These guys. They know.

Well actually I am a mechanic by trade and I've prob rebuilt more engines then you have seen.

Your whole concept is flawed, that fact you think running lower comp on an n/a motor is better just shows you lack of knowledge on how to get power out of an engine. You dont see TRD or Spoon selling decomp pistons for n/a's. The higher the comp the bigger the bang = more power, low comp equals fail town for an n/a, the reason guys decomp to go turbo is for greater protection from detonation so they can run more boost.

So stupid were you earlier comments I thought you were just f##king with the op, Maybe I should go and bash out my air flow meter and gain some killer wasps on my n/a.

This just doesn't make any sense. I mean. You don't want big bangs in your engine. That shit would get hot. And melt shit. Fark that. Small bangs mean less heat, and everyone knows less heat = moar fast. Are you sure you're a mechanic? I played with lego once...

Anyone who disagrees with this simple logic isn't a mechanics sphincter.

I'm not going to justify this mod anymore after this post.

The pics are there, the write up is there and the dyno sheet is there.

The engine won't grenade if you gut the AFM as it will richen the mixture enough for the small amount of boost generated.

End of story, anyone who knows a car from a bar of soap will agree and it's obvious who the dickheads in this thread are.

What if the bar of soap is shaped like a car? Cos it gets hard for me then...

SIMPLE LOGIC!

THATS IT IM OUT OF SIZES NOW. SO YEA. I GUESS WHAT KAWA SAID. IM GOING NOW. BECAUSE IF I KEEP TYPING THERE WILL BE NO MORE ROOM FOR YOU LOT TO ARGUE WITH THE MASTER!

Op - if you want to try this mate I have a spare de throttle body that I was planing to use to make this set up on my old rb25de motor until I spun the big end and bought the LS, if your in se qld mate you can have it as its no use to me anymore :)

no...it doesnt make sense...the simply logic is that the car simply wont run above idle with the 2 throttle bodies closed...therefor I cannot get enough air velocity in the intercooler to open the first throttle body..so my question is

how am i supposed to overcome this...??

i can not ask this question any more simply and if you cant answer it, then you neither are a mechanics sphincter...

Are you serious?

Throttle bodies are never completely closed, the one on the engine opens up with the throttle cable, it sucks air passed the slightly open throttle body on the cooler and acts like a normal car.

The pipe work between the two coolers takes a short amount of time to fill up with air, but it's not noticeable in a real world situation. It's probably the equivalent to the lag experienced by fly by wire throttle set ups.

Once the car is moving and the cooler fills up and the first throttle body is forced open, it acts very similarly to a turbocharged car coming onto boost.

where are you getting this garbage from....throttle bodies are completely closed you goose...until you push the accelerator air is bypassed through your idle control valve and that is what makes it run...when you push the accelerator the throttle body opens and air rushes into the engine cause the revs to rise so the car can move....its simple logic...but in your setup when i push the accelerator according to your "logic" there will only be a small amount of air in the pipe that wont last very long at all and thats assuming you have a leaky throttle body..so i very much doubt its going to last long enough to get the car up to a decent enough speed to create 6psi of boost in the intercooler.. I guesstimate this would take at least 20 mtres of driving...where is your air supply coming form for that 20 mtres?? and its going to take even longer to build up pressure if you have a leaky throttle body....

Obviously you have to set the first throttle body so it's not completely closed but not open enough that it lets the air passed prematurely.

If you're really worried you can warm the car up, disconnect the IACV and increase your idle speed so you can move without touching the accelerator. It's not necessary, though.

on a side note has anybody seen the BMW4219ELi...

its utterly amazing..It's made to fulfill a small boys dream. The BMW 4219ELi, It’s powered by 19 Porsche boxer engines, each producing 459 horsepower for a grand total of 8721 it has 42 wheels and a Motorsport spoiler.

Due for Le Mans 24hr in 2014

I wonder how many throttle bodies it has??

I still can't see how the system gets ANY positive pressure.

The air is trapped inside the cooler and it can't escape until the throttle body is forced completely open, then the air rushes into the engine.

The dyno sheet doesn't lie dude.

Only needs two.

The dyno sheet doesn't lie dude.

but how does it get into the intercooler in the first place when there is nothing there to suck it in???

It's forced in there through the pod filter.

Air takes the path of least resistance, but if there is a duct going to the pod, it has nowhere to go other than through the filter and into the cooler.

well i dont see any duct on your car and the car has to move first until then it cant be forced in...and unless your have your IACV set at 2000rpm, until you open the throttle body the car cant move...do you see where i'm going man....

anyway i have to duck out for a bit just think about ok...

    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
    • OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
