Double Throttle body

[KeWLKaT]

His theory:

Why bore a TB to 58mm when you can have two 53mm ones!

My theory:

Can you say overkill?

And on top of it this is in an accent!!!!

I see you drooling Ford :tongue:

[tharptroy]

that kind of setup isnt done very often, and the reason isnt because it works well
=P.

[KeWLKaT]

you know you love it :D

no more making larger throttle plates!.

No risk for hydrolocking if one of your intakes is shorter :D

[tharptroy]

the amount of fabrication that it took to make that setup is WAY more than making a larger throttle plate, lol.

the sad part is that it probably doesnt give you much more power (if any).

[KeWLKaT]

Hmmm... Well, I hope I can add my question here though.

The fact that it pulls ''more air'' or maybe more like the fact that it CAN pull more air.. Doesn't it make it possible to add some larger injectors without boost? (like they do on mazda rotary engines?)

[tharptroy]

the cross sectional area of the throttle body is not much of a limiting factor for this application.

so in actuality, you probably wont be pulling that much more air, and consequently, you wont need more fuel

to determine if you need a larger TB, keep an eye on the MAP sensor readings.

if you have alot of pressure drop at higher RPM (WOT of course), then you may want to think about an upgrade

[KeWLKaT]

Ok, I got what you mean.

Here's one other question though: how could it be that things like these happen to cars? As in, one mod would apply to me but not to you? You know what I'm trying to say? Is it because of the way it's driven? Or because of external factors such as climate and atmospheric pressure?

[FordFasteRR]

the manifold pulls in air and creates vacume, if you open up a 2nd source of air it reduces the velocity of the air and causes turbulence which in turn yields less cylinder filling.

The only way that I see that design gaining any reasonable power is if the motor is built up with bigger cams and higher compression, no less than 12:1 static + big cams...

Otherwise it can't make use of the higher volume and the drop in air velocity would kill the power.....


pointless.

and on that note:

shawn :)
