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...

Ah man... Kwaka man I love the effort you put into that, but I swear posts like that are what breed the next generation of simpletons!

Good son of rajab... Kwaka... I am just going to sit here and applaud. Why I never thought of cooling ambient air with ambient air is just a kick in the nuts. And I spent all that money on turbocharg

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...

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.

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 so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil

      Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.

      Unsolicited advice? Keep the engine as close to stock as you can. Nothing wrong with adding some boost and making a little more power, but given where you are, you really don't want to try to make it into a monster. I can't imagine the roads are up to it, and the lack of locla support when it grenades will be a ball ache. FWIW, If there is a dyno around that you can access, then brand new injectors are a good idea, which will lead you to (at least) putting a Nistune in it, which will allow you to put an R35 AFM on it, all of which will make it possible to make it much much nicer to drive and live with.
