Does anyone know what the CFM this engine flows throught he intake?? I'm building a air box for my desert car and need to figure out the right size filter.

 

3.5L what? J series or C series? That would help

 

Ahhh it's a 1999 Honda Odessy 3.5 I dont know which series!? Hope this helps.

 

its the j35a1 so go from there idk much about j-series but try another forum specific for the J-series

 

You have to pick a max. rpm.
But if you wanted to spin it to 7200, for example:
3.5L = 214 ci
214 x 7200 x 1.0 (VE) / 3456 = 445.8 cfm at 100% VE

 

Thanks sc_at_kfi that helps alot... I got it from here.

 

No prob. That's what I do.

The phone isn't ringing at the moment; if you want to go one step further, once you know how many cfm an engine can pump, you can calculate how much mass that air has (cfm x 60 = cfh / 13.07 = lb/hr air) and if you know what fuel you're going to run - you can calculate how much fuel you need to mate with that air. (this is how we fuel for engines that have never been "run" before, we do crazy combinations all day)

so 445.8 x 60 = 26,748 / 13.07 (13.07 cubic feet of std. atmosphere air = 1 lb) = 2046.5 lb/hr air

so if for example, you run pump gas and target a 12.2 WOT AFR

2046.5 / 12.2 = 167.7 lb/hr fuel
167.7 / 6 = 27.9 lb/hr per cylinder

whats the stock injector size, ~28 lb/hr?
