Is there a way to calculate ideal throttle body size?

Is there a way to calculate ideal throttle body size?

Rule of thumb is to go 10% over because a naturally aspirated engine can go above 100% volumetric efficiency. Go above that and you will kill low end because of reduced velocity, go below that and you starve the engine for air at top end. 110% is volumetric efficiency is 319cfm.”

What kind of throttle body does a Mazda 3 have?

Mazda 3 2.0L / 2.3L 2008, Throttle Body Thermal Gasket by Weapon-R®. Brand has developed a special high temperature insulating gasket which replaces the OEM intake gasket.

Can you put a Q45 throttle on a 3SGTE?

In other words, the ability to just tip into the throttle a tiny bit goes out the window which is fine on a track car, but sucks on a “mellow” street car. Theoretically you could install a Q45 throttle on a stock 3SGTE and it would work fine but would give you a bit less finesse over low throttle modulation of airflow.

What causes the size of the throttle body?

From there on the principals are the same. Power, rpm, head design, cylinder capacity, the position of the throttle body in the inlet tract and the position of the injector all affect the size of the throttle body to be used.

How big is a H-D throttle body size?

I believe 54 mm is stock up to 2007. Then I think 58 mm is used 2008 on for TC-96 and TC-103 applications. I believe you can get 62 mm and 64 mm sizes for higher HP engines. Are there other sizes around?

Where are the injectors on a throttle body?

By moving the injector towards the end of the trumpet you give the air and fuel more time to mix. This gives results at high rpms, but the pay off is driveability and throttle response at lower engine speeds. You can run multiple injectors per throttle body. For most applications the two injectors will be in the same position.

How does an individual throttle body work in a supercharged engine?

Individual throttle bodies work with turbo charged and supercharged applications and provide the same benefits to the engine and driver as normally aspirated. A forced induction engine will still require a plenum chamber to feed the pressured air from the turbo to the cylinder with the throttle bodies sittin between the plenum and the head.
