Vararam VR-SDR GTO/Holden - Manual (Page 9)

FAQ
Q: Do I need to custom tune the car after the filter installation?
A: ANY vehicle benefits from a custom tune, but NO, you do not have to custom tune.
Q: My check engine light is on.
A: DO NOT PANIC, just allow the vehicle to learn the airflow this takes about 100 miles of driving in
low and high RPM operation
Q: How often do I clean the filter?
A: The filter should be cleaned about every 8-10,000 miles.
General Tech Info #1-
This kit was built from day one to incase the airmeter inside the air box housing to help shield the
MAF from heatsoak. The system was built as a cold air, however, in testing it proved that through
data logging using HP tuners software that it would deliver colder than ambient temps. This is caused
by forcing air through the airmeter, which shows some ram effect. This has been reflected in the units
high MPH improvements through the 1/4 mile, usually +3 mph on stock cars and +4 mph on modified
vehicles making 500 rearwheel HP+. Due to the GTO/ Holdens weight we concentrated the airboxes aero
package at shift recovery (4,500-5,500RPM) and in low end response to speed up engine windup, You
will find that in real world testing there is “NO OTHER COLD AIR/ RAM AIR SYSTEM AVAILABLE
ANYWHERE” that can match the VR-SDR Systems on road/ track performance, NOBODY, NO
WHERE! Sorry AUSSIES your kits don’t even come close! We guarantee it or we will take the kit back!!

General Tech Info #2-
The GTO/ Holden system (VR-SDR) has gone through one of our most intense development programs.
the reason we took the time we did with this unit was because the car its used on has a massive amount of
variation, from motor alignment side to side front to back etc... If you look down the center of the car at
the motor it is actually twisted in the frame. There is simply no clear geometry , so we designed the kit to
move around side to side front to back with high mount throttlebodies as used on a blower combination
and stock mount as well.
If you run into something we have not compensated for, simply give us a call at 713-477-8100 chances
are our R&D dep has a solution, they built over 24 GTO prototypes and street/track tested them all with
different mounting combinations so chances are we have the fix for your particular vehicle combination.
The filter - This may look small to some but make no mistake all VR filters are engineered to be as
compact as possible while maintaining minimal pressure drop across there surface area. We have spent
years designing street and race filters using all types of materials, foam,paper ,cotton gauze etc..Our
research has enabled us to establish formulas for every filter combination of pleat spacing and depth to
maximize both flow and filtration. The GTO Holden street units are rated up to a whopping 1500CFM!
(Race filters are available that can top 2000CFM)
