Last I heard, the second TB would not open until a specific throttle position.

 

That's a peculiar design. I've never seen a sequential TB sustem, just a row of 2 to 4 TB's that all open symultaneously.

 

On a turbo application you're forcing in the air... This is an N/A mod.

Connect 3 straw together in a Y shape. Put the upper part of the Y shapped straw and start sucking air in? Are you sucking in more air than you would if you had only 1 straw.

Now take 2 straws and put them both in your mouths. Which setup breath the best

 

One Mirage guy spend a long time trying to make his car run with ITB and EMS. I believe it took a year or even longer and still couldn't get it right.

http://www.rpw.com.au/ has some more info on IM with twin throttle body setup reusing the stock MAF sensor!

It's entirely possible to tune an EMS (or any other standalone) with multiple TBs. I guarantee the person tuning either didn't know what he was doing or he had other problems.

 

I bet it's possible to tune ITB with EMS, I didn't know you can use TBS. Always thought a MAP sensor would have to be used.

 

TPS. Yeah, it's the preferred method for ITB setups, so I don't know why it wouldn't be for dual TB's.

You would probably benefit most from a TPS/MAP based tune, but I'm no expert. I just know what the manual tells me and what I've read elsewhere.

 

Just checked out couple of the old threads and 'yes' you were right. It doesn't seem like quad throttle body will make car not drivable on the street.

I stand corrected.




Everyone is saying that ITB sounds awesome, do you know where to find a sound clip or something?

 

I like my setup, but its hardly an NA monster. Still needs fuel management, flash/piggyback and a host of other things (hell I still need an exhaust).

 

my na setup on a certain budget

rmr intake-150$
rrm throttlebody-350$
4g93 mani (100 used) port urself-100$
head work-250$
rpw header + downpipe-550$
custom exhuast-200$
bored fuel rail-100$
pulley-100$
piggyback-400$

 

Id hold off on the fuel mods at first.

Extremely light-weight wheels (under 12 lbs each)
very good tires

Do all of the exhaust and Intake Mods. Headers, Downpipe, highflow cat, center pipe, axle back, intake, intake manifold, throtal body.

Then move on to cams and pistons, keeping in mind how one will effect the other when your purchasing.

Then remove your AC/power stearing belt (or the entire systems)

Lightened crank pully

Flywheel and clutch

Limited Slip

grounding kit

plugs and wires

FMU (greddy Emanage or AEM ems), piggy is okay but you are looking for the ultimate setup.

Port and Polish.


Then you can start to move on to some fuel mods tuning as you go with your stand alone FMU.

 

Of course if your are just looking at the 1/4 mile, which most of you kids are, you can try this method. http://crazyjim.ramelot.com/14seconds.htm Definatly the cheapest way to get a sentra in the 14's, and it can easially be applied to any vehicle.

 

AHHAHAHAHAHAHAHAHAHAHAHAHHHHHHHHHHHHHHHHHHHHHHHHHH HHHHAHAHAHAHAHAHAHAHAHHA

YES!

 

Hilarious. Best part was how they made it a convertible to impress the ladies.

 

Yeah, the Sawzall Sentra was my avatar back in the day. I'll cook up a list of how I'd build an NA Lancer, but when I do it will be done as if I had a lot of money.
