Could you run rrm's stage 1 turbo kit with a twin throttle body? Because i read that you cant run a quad. But i havent heard about the twin. I am just curious

 

It would be hard as hell, dude.

Run the turbo on one TB. You'll get more than enough power.

Once again, multiple TB kits are for N/A motors trying to squeeze out more HP. Turbo applications don't squeeze HP. They create large amounts of it.
To repeat myself from the other thread, just because it's a good N/A mod doesn't mean it'll make a turbo better.

 

well that one guys twin tb has a single pipe going splitting into 2, which apparently helps. i asked him about this when we found the new twin tbs
heres what he told me:

It would be very easy to work with a turbo setup, as both throttle bodies are connected to one pipe which leads to the intake/mas. I could also weld the charge piping that connects air intakes instead of using silicone couplers such as on the n/a setups. I make quite a few of these setups for 1.5/1.8 mirages and I have just built 2 setups for the 2.0 lancer.

so it can be done, i dunno what point would be though, i forget why he said the twin tb was better even though it went into one pipe, check the site

 

Yea i dunno i was just wondering didnt know if you would have to custom fab the piping or what

 

well lets think about this for a second. why is two throttlebodies better than one large one? two smaller throttle bodies have more area to let air pass through than one large one. take two 2.5" circles and compare them to one 3" cirlce. that's 9.81 square inches vs 9.42. also, air will flow faster(though not always particularly more in volume) through a smaller opening than a larger one.

so then the last concern(in regards to flow) would be whether or not the pipe that connnects the two throttlebodies and the intake system together flows enough. as Dave at RPW commented, you'd only be holding potential back with a joint intake system for the twin throttlebodies. i only believe this up to the point of designing the whole intake system to flow enough. Ford has twin throttlebodies going to one intake system, albeit their throttle bodies is in one assembly with both inlets side to side. with a well designed system, twin throttlebodies is great for an NA app.

in regards to turboing with twin throttlebodies, what would be the point? air delivery has changed from pull to push. with the pipe joining the two throttlebodies, you're creating more volume air has to fill before boost (positive air pressure) is created into the engine. larger amounts of air will be able to more freely enter a larger throttlebody than two(depending on size).

so do your homework and stop adding two great ideas thinking it'll make one better idea. it doesn't always work that way unless you've ironed out the details. happy studying.

 

Wow ok that explains it alot better. Rhyzin your the man

 

Tune one system at a time.

I have seen quad and twin TB systems for SR20DET on ebay, and I haven't seen one person in the US has ever tried it. It should tell you something.

Also, from past miragers, no one had any success w/ them. In Aussie, yes, because they have closer tech support.
