Out of curiosity, I was wondering what the differences are between a single blade throttle plate (LS1) and something of a 2 blade throttle body setup (LT1). I was wondering about the fluid mechanics of it: flow ratings of similar areas (if the single plate setup had the same area as the 2 smaller plates combined), also would there be any discernible difference in power, given the same engine but different throttle body setups? Finally, is there a distinct advantage of using one over the other?

 

Yes the ls1 tb flows better I believe the main reason for the twin lt1 tb was for hood clearance, but I could be wrong

 

If you go to a monoblade any advantages of the LS1 are gone.

 

The LS1 does have a single blade.

 

he is talking about the monobladeLT1 TB that arizona speed and marine sells

 

Ah, I didnt know there was such a thing. I went to their website and it looks pretty sweet! Are there any members here with it on their car?

 

Plenum volume mean anything?

I would think the separation in the middle of the two throttle blades would disrupt some airflow.
