NOISE BOV *
for street or track conditions at a twist of the
until now, making your machine quiet for normal
street use, has meant pulling your BOV off and putting
it back on when you want track conditions.
Not surprisingly, it's been every enthusiasts dream
to have a superbly engineered BOV that has absolute
maximum throttle response and power in Full Blast
mode for the track ... and with a flick of the wrist,
runs quiet for the street.
this amazing breakthrough is now a reality, the
latest in a string of Aussie innovations from Sydney-based
hybrid technology experts,
GO FAST BITS.
It is, as its name implies, the ULTIMATE
performance breakthrough in BOV technology, pioneered
in the GFB developmental lab. It is ...
The PERFECT stealth blow-off valve!
By utilising a unique air diverting system you control
exactly how much air you dump to the atmosphere
for noise, or the inlet for silence.
sending the vented air back to the inlet (rather
than muffling it), there is no restriction and the
still operates at maximum efficiency.
cars with sensitive air flow meters, the valve can
be tuned to vent just enough air back to the inlet
to prevent backfiring whilst giving the loudest
possible blow-off noise. No more guessing which
valve will work on your car - this one will do it
Now here's the cool part
turning the GFB world patented ratchet style head,
you can finely adjust the amount of air that goes
to each venting port, giving you complete control
over how loud your gear changes are!
advantages of this system, combined with GFB's other
proven features are numerous...
control over how loud your shifts are!
By simply turning the lower ring of the cap, you
can adjust how much air is vented to the atmosphere
or to the inlet, giving you complete 'noise control'
over your shifts!
cars with sensitive air-flow meters,
you can dial in the valve to eliminate common
problems normally associated with aftermarket
valves... and still get a great sound.
tools needed for spring adjustment.
Spring adjustment is achieved by a unique
mechanism contained completely within the valve,
meaning that no tools are required for adjustment.
This also ensures the profile remains as low as
possible, as the cap does not move up and down
piston seals achieve the best possible seal
on both ends of the piston. Now, as well
as our acetal piston seat, a low friction, lubricant-impregnated
polymer piston ring is incorporated. This system
is far more reliable than o-rings, which require
frequent maintenance and replacement.
engine bays are NO problem!
The vacuum nipple is free to rotate through
360 degrees to make fitting easier.
