EVENTURI EVE-FK8-CF-INT Intake system HONDA Civic Type R FK8 (carbon fiber)

Performance Increase : 14-20hp, 22-29ft-lb
V-Box Acceleration : 60-130mph Reduced By 1.2 Seconds

The Honda FK8 Type R intake is the result of extensive design iteration through dyno testing and flow analysis. It was developed to achieve two objectives – 1) Maintain low inlet temperatures. 2) De-restrict the turbo inlet path. The first objective was met by enclosing the filter inside a carbon airbox and using the stock seal against the hood to block out the heat soak from the engine. Since the intake sits directly behind the radiator it is crucial that the filter is not exposed which would result in a loss of power through high IAT. The second objective was met by removing the flexible tubing and optimising the inlet path with a Venturi stack connected directly to the filter. Furthermore, we added a second inlet to the airbox with a scoop pulling in air from the inner wing area. This almost doubles the total cross sectional area through which the turbo can draw from as compared with the single entry on the stock system. Our carbon airbox enclosure has been designed to maximise the use of the available volume and block all sources of heat. The resulting performance gains and aesthetics are industry leading for the FK8 Type R.

The standard airbox draws in air from a single entry duct behind the front bumper. The size of this inlet is very small at approximately 35cm^2. The demand from the turbo results in this opening becoming a restriction. However, simply opening the filter inside the engine bay is detrimental since the filter position is directly behind the radiator and once the engine warms up - the filter will become quickly saturated with heat. Our intake system solves this issue by keeping the filter enclosed inside an airbox and adding a secondary feed which opens the inlet area by another 28cm^2. This coupled with our Venturi Filter stack for smooth flow results in an immediate gain across the entire RPM range of 14-20hp. The dyno graph below shows the comparison between the stock airbox and the Eventuri intake system on a standard car with standard map and exhaust. Dyno runs were done back to back on the same day and with the hood closed. The following dyno results are from independent tuners around the World:

__BR Performance - Belgium__

__Road Testing__

We also carried out road testing using a Vbox unit to record the acceleration from 60-130mph (also 100-200Km/h). Testing was conducted on the same stretch of road - again on the same day to keep variables minimum. Results show that with just the intake added, the acceleration times from 60-130mph and also 100-200Km/h reduced by approximately 1.2 seconds which is a significant change at such speeds.

Acceleration results summary:

• 60-130mph with Stock intake = 15.45 seconds
• 60-130mph with Eventuri intake = 14.27 seconds
• 100-200Km/h with Stock intake = 13.04 seconds
• 100-200Km/h with Eventuri intake = 12.17 seconds
