How do I choose the right size throttle body?
There are several factors to consider when selecting throttle body diameter, power output, RPM, cylinder head design, engine capacity, injector position and throttle body position along the inlet path.
What size are Hayabusa throttle bodies?
45mm
Suzuki Hayabusa Gen 2 45mm Throttle Bodies.
Do individual throttle bodies increase horsepower?
When the throttle bodies have tuned velocity stacks, they can designed to produce much more horsepower for a specific RPM range. Individual throttle bodies also have lower pumping losses at partial throttle versus single throttle body systems.
What happens if you put a bigger throttle body?
A bigger throttle body means more air
And since the engine is basically a large air pump, increasing the air intake level will increase the engine’s power output as well, in some cases by up to 15 to 25 hp.
Does a bigger throttle body use more gas?
Speed Secrets: Does a Larger Throttle Body REALLY Gain Horsepower?
How much power do throttle bodies add?
Gains from a throttle body can be dependent on modifications. Generally speaking, anytime a throttle body is added, there will be some added horsepower. The amounts can range from 5-25 HP depending on what other modifications are done to the engine.
Why are individual throttle bodies better?
Individual throttle bodies not only offer superior response, but they also reduce these restrictions, freeing up power through improved airflow, with little to no trade off other than cost and increased engine noise.
How much HP does a bigger throttle body add?
15 to 25 hp
A bigger throttle body means more air
Is it better for bigger throttle body or smaller?
Another important factor when it comes to the power gains offered by the throttle body is engine combination. From the most basic standpoint, the higher the power output of the test motor, the larger the throttle body required.
Is a smaller throttle body better?
The smaller bore means you will apply higher throttle angle for the same power level–and that is a good thing because it increases the volumetric efficiency of the intake.
How much HP do cold air intakes add?
5-20 horsepower
Cold Air Intakes are said to improve your vehicle’s performance by 5-20 horsepower. This number will vary depending on the make and model of your vehicle. While this isn’t enough power to put you back in your seat, it will give your car or truck a little pep in its step.
Do I need a tune for a bigger throttle body?
For pre-2005 vehicles, a tune is not required with the addition of a new throttle body. For 2005+ vehicles, a tune is recommended for throttle body changes & updates.
What mods add the most horsepower?

How much hp does an air filter add?
about 3 to 5 HP
And if your engine is getting more air, then it can perform better. In fact, a high flow air filter can actually increase your horsepower by about 3 to 5 HP and increase your torque as well. At the same time, this can lead to increased fuel efficiency.
How much hp does full bolt ons add?
It’s not all bad. That may sound discouraging, but here’s some better news – you can feel a 4 percent increase in torque and a 2 percent increase in horsepower when you’re driving. If you think your car is making a bit more power, that’s because it probably is. Just not as much as you might have hoped for.
What happens if engine gets too much air?
To sum up, if the engine gets too much air, the lean air-fuel mixture will result in engine overheating. So, it is always better that the engine receives both the air and the fuel in the right proportion.
Can K&N filter damage engine?
We researched these filters and their impact on vehicles so you’ll know for sure whether they live up to the hype or are a detriment to your vehicle. If you properly use a K&N air filter, it will not damage your engine. However, those who accidentally overoil this filter may have some damage done to the intake.

Is it better to run lean or rich?
Q: Is it better to run the too lean or rich engines? An engine running slightly rich will give more power, but running lean will cause catastrophic engine damage. Running too rich can also cause severe damage to your engine.
How do I know if I am running rich or lean?
Looking at the stochiometric ratio again, if there is too much air in the cylinder, meaning the parts of air compared to the parts of fuel is higher, your engine is running lean. If your engine has a ratio where there is more than 1-part fuel per 14.7 parts of air, your engine is running rich.
Do K&N filters really make a difference?
He finds that on the dyno, the aftermarket filters do in fact make more than the OEM unit, with the most gains produced by the K&N filter (around four horsepower and five lb. -ft. of torque, or around 2.6 percent and 3.7 percent, respectively).
Are K&N air filters really better?
This reduced maintenance and cost would make K&N Filters attractive even if they supplied the same level of airflow as a paper air filter. But airflow tests on K&N products have shown superior airflow, even when the filters are at their 50,000-mile cleaning interval.
How much hp do headers add?
So how much hp do long tube headers add? If attached to a stock engine, you can expect about 6-9 hp over a manifold.
Does straight pipe add horsepower?
