</p><p>Well, the results were:<br>
- 137.0 RWHP with a generic pod filter <br>
- 145.4 RWHP with the Racecraft intake<br>
<br>
Just to provide some brief detail on the test..<br>
<span style="color: red;">Disclaimer: This test is done by me and i'm
revealing what is displayed in the chart. But please don't take my word for it
It is a very rough guide and it's not very detailed. It may be bullshit. yes,
yes, there are many factors that contribute to the results, etc etc. Take it as
a referance or something to read about if you wish. So, possible skeptics, i
respect your comments but if you with to comment, please think before you speak.

Before Processs:<br>
-Generic pod filter with no heat shielding from the engine heat<br>
-Air conditioning turned on<br>
-Dyno was done with the bonnet closed..<br>
-Temperature sensor place near air filter pod<br>
<br>
engine compartment temperature near the intake area in length of 5 minutes was:<br>
53 ~ 58 degrees celcious with the auxilary fan on simulating driving<br>
70 ~ 75 degrees celcious without auxilary fan on simulating jam/idle<br>
<br>
137.0 RWHP<br>
202nm<br>
</p>
<p><br>
After Process:<br>
-New intake fitted<br>
-Aluminium hose channeled from grill area into intake opening<br>
-Air Con turned on<br>
-Bonnet closed<br>
-Temperature sensor fitted into intake<br>
<br>
engine compartment temperature in the intake area in length of 5 minutes was:<br>
32 ~ 33 degrees celcious with the auxilary fan on simulating driving<br>
33 ~ 35 degrees celcious without auxilary fan on simulating jam/idle<br>
<br>
145.4 RWHP<br>
204 nm<br>
<br>
~ 8 RWHP increase is pretty significant.... <br>
<br>
Disclaimer 2:<br>
Possible contributions could come from the not-so-clean generic air filter
pod, closed bonnet enviroment, limited air from auxilary fan, air temperature,
air density, engine behaviour, engine condition, clutch slip, technical aspects,
technician's consistency, etc<br>
<br>
<br>
As dyno to dyno are pretty different in terms of readings, <br>
the dyno in different facilities revealed different figures....<br>
This is after the MAF conversion and before the new intake where i got:<br>
165 RWHP in Visworks (JB - Dastek Dynamometers)<br>
137 RWHP in Links (Sunway - Hyper Power Dynamometers)<br>
<br>
hmmm.... but i'll take the one with a lower figure <!--emo&

</p>
<p>Verdict:
<br>1) Performance Figures:
<br>Seriously, the gains achieved seems almost unbelievable. There will be doubts
and suspicions I'll leave it to the dyno chart for you to decide. There are of
course, crucial factors to consider, in terms of the enclosed engine bay
enviroment which produced huge amounts of heat and especially when tested right
after heat generated under such condition. Again the results are as above.
<br>2.1) Feel: Scenario 1: Low Speed cruising to full throttle
<br>I noticed a difference in increased acceleration especially during
accelerating while cruising at low speeds which most probably, is due to the
pressure collected in cool, dense air buffer contained in the intake barrel.
<br>2.2) Feel: Scenario 2: Full-throttle to partially closed throttle to
Full-throttle
<br>Significant difference was also felt during re-accelerating from partially
closed throttle back to full-throttle which, due to the similar fact of the air
buffer collected.
<br>3) Sound:
<br>Sound wise, for loud induction freaks, sorry to disappoint, but induction
note has been significantly muted. Compared to other open-type pod filters, like
my sponge filter pod before, you would notice a decrease in induction note
though deep-throat noises still does linger in the barrel. It is actually due to
the fact that the sound absorbent fibrous nature of carbon fibre barrel
construction as opposed to the nature of plastic cylinders which amplifies
sound.
<br>Pros:<br>
-Practical choice for performance upgrade<br>
-Value for money
<br>Cons:<br>
-Might not fit smaller cars<br>
-Induction sound sacrificed
<br>Summary:<br>
Overall, I love the product. I love it for the wow-factor, the price, the
performance gains achieved, the fact that I now have a carbon fibre product in
my car and most importantly, there's nothing i don't like about this product. So
that's my summary. </p>
