Well we have achieved all
our initial aims for Project VE getting it into the 12's but
as usual we want more .
Before progressing
further into the cammed combo's it was time to look more
in-depth at intake options
as more come onto the market , last issue we looked at the
new CSV intake which worked well but we also have been
testing both the "Russo" OTR and the "Orssom" OTR , all
showed potential in different areas .
CSV intake
The Orssom intake looked
to be a winner with its factory integrated look , the large airfilter and a smooth intake passage showed potential
, future plans call for it to be made from moulded plastic
but initial prototypes are fiberglass the same as all the
other intakes we are testing ,fitting was easy utilizing the
factory shroud mounting points and a rubber bellows to fit
the intake in place .
Dyno testing showed gains
over a normal intake or pod setup but marginally down on the
CSV intake we used as our baseline , removing the top cover
to expose more of the airfilter found the power climb to the
same as the baseline power of the CSV intake, on the track with the cover
trimmed to increase airflow we achieved a
12.79@109.7mph . Further testing showed that trimming
the cover fixed the slight power discrepancy.
Orssom Intake
The Russo intake looked
like it had lots
of potential with its design calling for the radiator to be
laid back so the intake could scoop cold air from in front
of the radiator , also featuring a larger airfilter design
than the CSV which helped it to recorded the best hp on the
dyno of 251kw and the best track time to date
with a 12.65@109.8 .Fitment
of the Russo intake was a little more complicated as the
radiator needs to be laid back and brackets fitted to
support the radiator but there where gains to be had from
sucking ample cold air from behind the grille.
Russo Intake
All the OTR's tested
required a intake air temp sensor to be wired in as they
where all tuned Mafless to optimize the airflow into the
engine
To finish of each OTR was
tested on the road to see what sort of heat soak effects
where evident , all maintained a few degrees above ambient
on the road with both the CSV and Orssom units heating up by
about 15 deg when stationary but where far better than the
std air box setup that saw 40+ deg above ambient when
stationary.
All the OTR's tested work
effectively and fitment will come down to personal
preference and if the car is a street car or a strip weapon.

Next issue we will swap
some diff gears and a cam into the car to unleash the
engines potential.
