Try service throttle body dulu bro, kebiasaannya lepas servis ok suda...
senang saja... kasi bersih saja bahagian dlm tempat adjust skru itu...

1) "What are Unorthodox Racing adjustable cam gears?"

An Unorthodox Racing lightened adjustable cam sprocket (Ultra T) is an
adjustable sprocket that enables enthusiasts/racers to adjust the
relationship between the crankshaft and the camshaft, allowing for
optimized cam angles. These changes in relation to cam and crank can
dramatically affect the peak HP, its placement in the rev-band, and HP
characteristics throughout the rev-band. Unorthodox Racing lightened
adjustable cam sprockets allow for cam degree changes of up to 10
degrees positive or negative. These sprockets are manufactured to
tolerances (.001") traditionally reserved for aviation, military, and
professional racing use and the timing marks on are cam sprockets are
held to within 1 minute of a degree (60 minutes being in a degree).

The timing marks are also engraved in the hard black anodized outer toothed
section, which vastly improves readability during adjusting because of
the wider spacing and the silver on black contrast of the marks in the
anodizing. Our Ultra T sprockets are lighter than their non-adjustable
OEM counterparts, following our tradition of reducing rotational mass
for enhanced engine performance. We use only the highest quality
stainless steel hardware (washers and bolts), 5 for each sprocket, so
you can enjoy years of flawless performance and looks. The 5 bolt
pattern assures that our sprockets will remained locked in place once
they are set.

2) "How do Unorthodox Racing adjustable cam gears give me more power?"

Changes in the relationship between the crankshaft and the camshaft can
increase HP in DOHC cars from 8-16 HP for normally aspirated engines
and 12-24 HP for forced induction engines. SOHC owners can expect small
increases in HP (2-4 HP) in certain parts of the power band. SOHC owner
can also shift their power curve from the stock setting to low-rpm
improvements (off the line enhancements) or high rpm improvements.
Adjustments vary depending on whether the engine is SOHC or DOHC and whether it
uses forced induction or is normally aspirated. We have found for stock
and mildly modified DOHC engines, whether forced induction or normally
aspirated, that 2-3 degrees negative on the exhaust and 1-2 degrees
positive on the intake (again varying slightly from engine to engine)
produce the highest overall gains throughout the engines RPM band. SOHC
cam owners can adjust their cam for optimized low-rpm performance
(amount of total adjustment varies from engine to engine and should be
done in one degree positive increments until peak low-rpm performance
has been achieved), by advancing their cam.

SOHC cam owners can adjust their cam for optimized high-rpm performance (amount
of total adjustment varies from engine to engine and should be done in
one degree negative increments until peak high-rpm performance has been
achieved), by retarding their cam. Owners who are beyond the basic
bolt-on parts would find themselves best served by having their
sprockets adjusted while measuring engine output on a dyno or at the
track.

3) "Will the adjustable cam gears void my factory warrantee?"

Actually the answer is fairly complex. Car Manufacturers state that if a
specific component is not designed by the original manufacturer, or an
OEM supplier specifically for use on your vehicle from the factory,
then that component voids your warrantee. This is an area that has been
a hotbed of controversy for years. SEMA has been working feverishly to protect owner's rights on this issue because many aftermarket products are viable replacements if not better
in design and function than the factory component. The federal
government has passed a law, the Magnuson Act, which forces
manufacturers/dealers to prove that the after-market parts installed on
the vehicle have caused the specific problem/s that have brought the
owner in on a warrantee claim.

Unorthodox Racing adjustable cam sprockets are one of many such products, from air
intakes to computer chips to exhaust systems. The simple truth is that
most dealers are looking for any excuse to avoid working on vehicles
modified with aftermarket performance parts because of their lack of
technical experience. If a product is CARB compliant, the component
being deemed a replacement part, it is more difficult for
manufacturers/dealers to reject warrantee claims and emissions
compliance.

The key is that owners must be aware that
these situations can arise and this is clearly stated in the back of
their owner's warrantee manual that non-OEM products void the
manufacturer warrantee. This not surprisingly includes performance
parts designed by car manufacturers (i.e. Ford Motorsports, TRD, Mazda
Competition and GM Performance to name a few). Owners must be aware of
the legislation that has been enacted to protect them from random acts
of warrantee voiding.

4) "Are the adjustable cam gears hard to install and how do I adjust them properly?"

Installation of adjustable cam sprockets is one of the more difficult bolt-on
installation. The key to the difficulty is the importance of sprocket
alignment to the factory specified alignment marks. These alignment
marks, installation marks, are only correct if the engine has been
located at TDC (top dead center). Add to this equation that some
engines use balance shafts and the alignment procedure can even more
difficult. Each of our sprocket kits comes with model specific
installation instructions, including torque specification on the
factory mounting hardware. But we feel that this installation is better
left to a professional installer unless the owner of the vehicle has a
good deal of mechanical experience (i.e. having done engine
disassembly, or camshaft installation before).

We have found through our testing of DOHC engines that 2-3 degrees retard on
the exhaust sprocket and 1 to 2 degrees advance on the intake sprocket
yields the best overall gains for stock and mild modified engines. SOHC
engines also gain HP, not quite the double-digit figures seen by some
DOHC engines, but they also have the ability to shift the power-band
from low RPM performance to upper RPM band performance. Advancing the a
SOHC sprocket will increase low rpm performance and retarding a SOHC
sprocket will enhance high RPM performance.

The adjustment or settings for both DOHC and SOHC engines can also be done
through dyno tuning which offers the most precise tuning of this
product. The additional money spent can mean the difference of more
than a few HP (or the shifting of the power band to a specific spot for
SOHC owners) especially on vehicles, which have more than the standard
bolt-on's.

5) "Do I have to change the timing belt's when I install the gear's?"

That decision should be based on a number of factors. First is the amount of
mileage accumulated by the belt, factory recommendations vary so check
your owners manual. If you have less than half of the recommended
mileage the stock belt can be re-used as long as there are no visible
deformities or abrasions. Anything beyond the half way point will
require close inspection and if even the slightest wear is visible the
belt/s should be changed for safeties sake, as the motor is most likely
driven aggressively and the recommendations do not take into account
the top ¼ of drivers (the performance enthusiast).

Safety is the key parameter in this decision as the additional parts and labor
cost at installation is much cheaper than engine damage at a later date
(many engines are non-clearance or interference and losing the timing
belt would cause major valve/piston damage). We recommend the use of
the factory OEM timing belts.

6) "Will adjustable cam gears cause my engine problems or to have premature bearing wear?"

This is a fear many prospective owners have and it is a valid concern since
we are dealing directly with the rotating assembly. This is a fear, as
far as Unorthodox Racing adjustable cam sprockets are concerned, that
is of no concern. Our lightened adjustable cam sprockets are
manufactured to tolerances (.001") traditionally reserved for aviation,
military, and professional racing use and the timing marks on are cam
sprockets are held to within 1 minute of a degree (60 minutes being in
a degree).

Unfortunately today there are manufacturers that offer adjustable cam sprockets but fail to follow the strict tolerances we hold in the machining process. The important fact owners
must understand, with rotating parts on the engine and accessories, is
that cam sprockets rotate at half the rate of the crankshaft. This fact
is of prime concern because it will take twice as long for an engine
problem to develop. Lastly our adjustable cam sprockets are lighter in
weight than the OEM sprockets.

7) "Will the timing belt cause wear to the teeth of the adjustable cam gear's?"

The hard black anodizing on our Ultra T lightened adjustable cam sprockets
is for long-term protection of the aluminum from the abrasion of the
timing belt. The hard black anodizing will not wear away on the belt
sections where the belts ride on the sprockets. This protection allows
for years of wear-free service and promises that your investment in our
products will be well rewarded with years of flawless performance.
Aluminum toothed sprocket sections must be hard anodized or they will
wear out in a few short months in a daily driven car and can cause
substantial damage.

8 ) " Is there any long term maintenance required with the gear's?"

The only maintenance required is to check and replace the timing belts at
the manufacturers specified intervals or sooner based on your driving
habits. In addition we recommend the periodic checking of the tension
on the five fasteners, we chose to use five fasteners for the added
security. The fasteners should be tightened in a star pattern and only
need to be hand tight; over-tightening is unnecessary and will cause
the threads to strip out over time. Other than these requirements you
basically bolt on the sprockets, adjust them to the desired settings
and forget about them.

hahaha.... bule-bule tanya '400m brapa ACP degree utk 4ag? Minta ampun lah saya soalan ikan basung tu tau! Urg adjust cam timing utk kasi increase loop degree supaya lambat tutup. Bukan bule tambah kuat pasang benda ni klu benda lain tidak di tukar. paling2 naik 2hp ja. Tapi klu suda brg cukup mcm injector, racing cam, titanium retainer, oversize valve, bule up sampai 15hp.

Buli tnya ka...??klu enjin myvi masuk nie barang ok kah????
skg myvi sy pkai surbo jak....
Juz want to noe...

Memang betul kalau psg retainer & valve besar/keras/oversize, racing cam & injector besar cc memberi banyak kesan kepada hp sesebuah enjin. Kena tgk juga darjah racing cam yg dipasang utk memaksimakan kemasukan bilangan angin & minyak masuk kedlm blok... terdapat banyak cam performance utk 4AG dipasaran seperti HKS, TRD & TODA Racing yg menyediakan beberapa darjah cam seperti 248°, 256°, 264°, 272°, 276°, 280°, 284°, 288°, 296°, 300°, 304°, 310°, 312° dan 320°. maka disinilah kegunaan ACP digunakan utk mengubah setting kedudukan cam samada advance +0.5 demi +0.5 atau retard -0.5 demi -0.5 sehingga mencapai kesan maksima respon enjin. Maka, sebelum setting 400m drag race ini perlu diset terlebih dahulu semasa membuat dyno test atau secara test run. Diharap jawapan yg tidak seberapa ini dpt menjawab soalan bro...
