Description:
Racing velocity stacks developed on dynotune (Dynojet i250) and tracks,designed to use on circuits and driveways. Prohibited use on public roads
-
Increase power and torque at the mid and high rpm
-
Greater rapidity of the engine to increase the revs on the whole power range
-
Greater reactivity of the engine during the throttle openings
-
Reduces the power decay of the engine toward the limiter
- Amazing intake sound
Dynamometers results:
Power/Rpm
Torque/Rpm
Test info:
Triumph Speed Triple 2009, Zard slip-on with map Zard exhaust
Blu line = Stock kit with AFR tune
Red line = Venturisystem kit (no AFR tune)
Contents of a package:
- 3 racing velocity stacks racing made by CNC machines
- 3 rubber gaskets
- assembly instructions
Warnings:
The kit increases the air intake into the engine so may need to adjust the AFR (air-fuel ratio)
More Air = AFR lean
Others results:
Power/Rpm
Power/Time
