dual throttle body intake??

dual throttle body intake?? Reply #1 – January 31, 2009, 02:01:54 PM Never seen one on a 5.0, but i know some older pontiacs and newer vipers have a dual snorkel intake - maybe the same idea? Quote Selected

Reply #4 – January 31, 2009, 04:31:48 PM Quote from: DVP;254650stock bottom it looks like.I wonder what the inside looks likeThat's a square runner lower, so it's most likely an aftermarket....could be from a truck but it looks like it's for an 8.2" deck.FWIW one 90mm throttle body has more area than 2 60 mm throttle bodies. The linkage would be a PITA to set up on that as well....Anybody ever work on the old 6-pak setups from Mopar? Quote Selected

I wonder how it would respond at part throttle tip in...The potential for maximum flow compared to a 90 mm TB would be less (by around 10%) but flow with the blades say......at a 10 degree angle may actually let more air in. If the lower could support the overall max airflow and the rest of the supporting combo were built for it, that might be one hell of a setup for average torque...Quoteyeah, but he says they are already connected on a pulley systemI saw that. I'd want pictures of that linkage and a pretty good description -- or better yet some type of presentation -- as to how it works....The fact that it's not shown made me think that it may not be finished. It will probably need adjustmentsat regular intervals... Quote Selected
dual throttle body intake?? Reply #8 – February 01, 2009, 01:49:35 AM im sure its just a hollow box.the trucks dual tb's have a rod linkage. For all i can tell, the cable might pass through the intake via a tube since it would be the straightest shot. Why does it look like there are two tps's?I like this sorta stuff so im bias., however it looks butt ugly. He could have achieved the same thing with an oxegen bottle and a tb at both ends.

Seems like you would never reach the proper stoich without the right setup like you said. Quote Selected
dual throttle body intake?? Reply #10 – February 01, 2009, 02:24:36 AM Quotepie R squared x h = v (for a cylinder) That's volume....For ease of math, we'll round ¶ to 3.14Using that # we get 6,358mm^2 for the area of a 90mm bore opening WITHOUT obstructions....For (1) 60mm bore we get 2,826 which multiplied by 2 equals 5,652mm^2Assuming equal airspeed between both setups, the single 90mm TB has more airflow potential -- provided the engine is up to the task of using the airflow. VE of the entire induction system would come into play. Quote Selected
dual throttle body intake?? Reply #11 – February 01, 2009, 02:55:50 AM but we are dealing with volume. I know the math using area comes out your way but the two are TB are working as one together. I think this is how the truck TB's get the low end torque made possible by the two throttle bodies allowing stoich to be reached at lower rpm typically expected from a truck.so your radius number would not be 30,,, it would be 60 (for the dual 60 math)assuming a 3'' tube of air representing the trottle body.....pi r2 3'' = volume of 33,912this puts the two 60's at more volume of flow.common sense tells me if i have two 6'' holes in a water tower, they are going to leak more water than one 9'' hole.two 60's would be less volume and less area if we were discussing dual plane intakes since each piston bank would only see a 60mm opening. In our cases , 86 and up, both banks see one opening for air volume. Isnt volume what its all about?I dono man,, i just look at things differntly, you do a lot researching and things so its your ball, just asking what you think. Quote Selected
dual throttle body intake?? Reply #12 – February 01, 2009, 10:13:10 AM The volume IS needed, however it becomes important at the intake runner lengthhttp://www.musclemustangfastfords.com/tech/mmfp_0501_ford_modular_motor_forced_induction/intake_manifold.htmlQuoteIntake runner length is one of the primary design features that determine the effective operating range of the motor. Longer runners will produce peak power at a lower operating range than shorter ones. This tuning effect is present regardless of whether the motor is turbo or supercharged.The volume of air taken in by an induction system will also be dependent upon it's ability to flow as a unit. This is where volumetric efficiency becomes an important factor asss well as Dynamic Compression ratio.It's similar to exhaust in that we want to get as much air in as possible AS FAST AS POSSIBLE. If I double the cross sectional area of the intake tract without doing anything else after (leaving stock heads) the average HP and torque of the engine combo WILL falter. Quote Selected
