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.

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...

    • Nah. Was just wondering if you were having a small stroke or if there was some slur/gaf/inside joke that I wasn't aware of.
    • That was a fark up, it's Salamanca Place I was thinking of. And now I'm curious as to what potential slur/gaf I have caused with Salamander Road, ha ha!
    • Actually everyone on the roads was really well behaved. The only person that did any minor tailgating was a local hoon in a Turbo Focus. Unfortunately we weren't going the same way so there was no grand initial D touge battle. Lots of people pulled over and let me through. The amount of "Hey man nice car, omg skyline, nice 34 man woo" was suprising. Like really suprising. Like almost annoying. My partner was obviously surprised, she'd never seen anyone in the real world point out the car/like the car/want to chat about the car before, so to have like 3 people per day mention it was notable, I could finally say SEE? SOMEONE THINKS THEY'RE COOL. Everyone was also pretty suprised about the weather. Every day was dry and about ~13-14C. Mount Wellington had a sign that said they close the gates at 9pm and I was heading up there at about ~7:30. It was VERY apparent that conditions were getting significantly worse by the minute on the way up and down. The road on the mountain was terrible though, it's no driving road. I have various suspension related questions now. Luckily it was only about 20 minutes from where we were staying to the top of the mountain as said Google maps. We only had the 2 nights in Hobart. We went to the Farm Gate Market though which was really good - And went down to the Hastings Thermal springs/caves down there during the day. I'd definitely be up for going back again, so luckily there's a few more sights yet to see. Didn't get to do the west coast/queenstown/cradle mountain so this was supposed to be a 'scouting' trip anyway of sorts if I were to one day do/take part in/organize a more car-focused trip. As for the boat, it wasn't bad. Well it was bad, but not in the way you're thinking. We did the night trip which leaves at 6:45 (though you have to be there ~2 hours earlier) and arrives the next morning at about 6am. There is nothing to do on the ship. If you plan accordingly and bring a book/tablet/show to watch/charger you can just chill out, take some Travacalm and just sleep through it. The food there is an extremely basic buffet that costs $32 a plate, or $14 for a $3 pizza. The way back we had a travel kettle and a few different types of cup noodles and made our own tea/coffee in the room. This was a far superior way to do it. At the very least book one of the rooms with beds. I guess as we were in the off season we didn't have room mates. You get an option for rooms with 4 beds (2x bunks) or a room with just the two bottom beds. There's also some option for a deluxe queen bed but it's much pricer. We've been on sleeper trains in Asia before so we figured this is similar (and it was)
    • You just gotta be really, really, really clear and decisive with what you want your end product to be. 99% of people who want this conversion aren't "I want to run a 295 front tyre!" so they don't really need the widebody. They just want the OEM body to look a little less dumpy, so bonnet, bar, skirts job done with some camber, stretch, slam. It's when you want that, but then decide to pivot later you get big problems. See also if you're willing to get an all in one fibreglass bar, and you're willing to accept fibreglass problems like cracking the entire item on a driveway, instead of just a piece attached to the bottom, etc etc etc. Decide this all before buyin'.
