what is needed for dual throttlebody intake?

[pocket-rocket]

Meh, I'm used to no aftermarket anymore... Aftermarket is overrated TBH.


Off topic (slightly). Ben asked me to try to think of a name and slogan for his company years ago before it officially came to be. One slogan we came up with was "Because stock sucks!" lol.

this thread isnt about what is better for what app, its what is necessary for 2. if you are trying to prove why one is easier/better than 2, your wasting your time because im just asking how to make the OBDI MPFI computer able to handle 2 throttlebodys.

regardless of when where why or how, id like to know what is required to make the computer able to handle the dual tb's.

to be fair i never said jack about the car or trans, for all you know it could be an jacked up LQ1 mounted to a 94+ T-56...

[robertisaar]

basically, there is not much difference required (electronically) for it to run correctly on an OBD1 computer...

[no_doz]

how is there not much difference? wouldnt the values need halfed? or would it just require the person doing the tuning to know & account for the dual tb's, & to use only one map sensor & assume both values are equal?

[robertisaar]

if making a common-plenum design, than MAP sensor would be no issue at all.

making the TBs feed seperate banks with no connection between: that requires some trickery...

[no_doz]

im referring to no connection between, as straight of a line from air filter to intake valve as possible-no 90* angles, 120* max.

[robertisaar]

MSPaint...

theres LOTS of ways to go about it, which EXACT one do you have in mind?

[no_doz]

ill draw something up a little later

Porshe trannies are Borg Warner. You should remember them, they make the T-5 "World Class" (more like world class piece of shit.) Major case deflection failure problems.

also, I talked to the makers of Raptor Transmissions..http://www.transmissioncenter.net/

They make a bullet proof 700r4, I've bought a few from them in the variing stages that they have available. We put a full raptor in our 1990 Ford Explorer 4.0L v-6 blown and nos. yes 4x4 and 4-door, it did 12.s. But we couldn't keep a ford A4LD together. every 3-4 passes and boom, another tranny dead.

Anyway, i talked to them about building a 4T65e with a northstar case, tranny in the Olds intrigue, because it would bolt up to my dreamer of a project, a 4.0L Aurora powered Achieva. The told me i would have better luck with them building a 4T80, that the 4T65e couldn't or wouldn't hold up to the toque and power output of the modded V-8. They said a 4t65e, built, could take around 450 hp, but it ain't going to live long, and under race conditions they wouldn't chance depending on it, maybe 6 passes and it's dead.

Now, since Getrag 284's are hard to find and I really want the consistency of an automatic, I'm kinda screwed. the motor and engine assembly is 6 inchs wider then my front end! Not the removable sub-frames, the main box steel that runs under and is apart of the strut towers. Also, my master cylinder needs to be moved 8 inchs to left of car to clear the head. Maybe some kind of linkage?

284's hard to find? Pssshh, I'm 2 of 2 when it comes to GM vehicles in my drive

I know about the A4LD. It has a bad rap on TRS. The Ranger guys hate it. Raptor transmissions huh? Fords SVT team made an off-road truck named the Raptor. It's really ugly if you ask me, but I would ride in it.

ECM isn't an issue. Even with separate plenums, you can still tie the 2 together with a small vacuum line to feed a single MAP sensor. A single TPS would be possible as well by just connecting the throttle plates together. About the only thing I could see an issue with would possibly be the IAC, but again, you could create a standalone IAC enclosure and feed both plenums off of a single IAC.

See a drawing I did almost 2 yrs ago...

[no_doz]

what would be needed to be done with the iac & where is it located at in a stock configuration?

[robertisaar]

on the 3x00s its integrated with the TBs, so i'd look around there on a 3.4. since the 95-earlier ones have the TB cast into the intake itself, its a little more confusing to me....

[bszopi]

Here are some shots of an IAC adapter me and another guy designed, wow, I guess 3 years ago. Give you an idea of what to do. http://60degreev6.com/forum/gallery/...p?c=17&userid=

And here is a thread (pics don't work ) discussing IAC adapters. http://60degreev6.com/forum/f109/mak...on-3500-t29285

I've read this thread start to end a few times and I'm still completely lost on what is to be gained from having two small throttle bodies. Seems like a huge pain in the ass. Wouldn't it just be easier to bore out the original and put a bigger plate on the existing single?
