So on that 2nd vid with the Renault engine, are we watching injectors just spray into the intake trumpets right there?

I would've thought F1 had a more sophisticated fuel delivery system than that, but I must be missing something...

 

Sick Can we get a group buy?

 

This is one of the most efficient ways to get the fuel to mix with the incoming air for a NA car (will also work well with a ITB+ turbo car if designed correctley). The velocity stacks create a swirling action with helps mix the incoming air and fuel together. In addition by mixing the fuel at this point there is an increase of air density due to the evaporative cooling of fuel in air (latent heat of evaporation). The cooling of the air stream at this point is more effective than then cooling effect closer to the actual valves; the reason is the available amount of surrounding air that is able to be pulled into the increased densities boundary layer at the edge of the velocity stack. More or less no restriction on the amount of air that is able to fill the air hole that is left around the cooler denser air.


Another reason it is done here is the increased mixing time for the Fuel/Air stream then if the injectors were place closer to the valves.



If there was to be an injector(s) failure(s) during a race the hole array is replace more quickly then if they were in the intake runners.

The injector array is located farther from the hot portions of the engine bay leading to denser/cooler fuel at injection; less chance of a burn for the mechanics or flare up this way as well



Tried not to get to technical.

 

Daym MugenRioS2k, you answered my question!

Not technical at all, hehe

 

sick...i wonder if the Honda's V10 would ever make it into the new NSX

I was at the library listening to this on headphones, my poor ears

 

OMG i think im stuck to my shorts

 

WOW!!! That thing sceams!!!!

 

TWM makes a setup like this that will work on the S2000 throttle bodies.

that is nice

dont try to pass CARB

Build a box around them and then run FI
