Project Civic on the Dyno

Project Civic was put on its maiden dyno run at Pro Dyno in Kuching last Saturday, tested on the very 1st dyno machine brought into Kuching, if not the state which, was only set up & commissioned recently. The availability of these test machines would definitely give a big boost to the local tuning scene; as prior to this, to get a thorough quantitative & qualitative gauge on their engine performance, enthusiasts could either a) take out the engine, pack & ship it to KL, b) ship the whole car to KL, or c) put it on a trailer, or drive it to Brunei ~ just to put it on a dyno test *maybe PUSPAKOM would have one, but they're strictly for inspection only*. For a start, there are rumours that 2 more of the dyno machines are being shipped in ~ that's just a testament of the maturing tuning scene here =)

It took quite a while to prep the car up for the dyno run & getting machine calibration settings set. The machine is a 2-wheel dyno manufactured by Dynojet. Okay, i'm not going to bore you guys with anymore mundane details, but a couple of amusing dramas did unfold during the session; here are some photos & captions posted by the Pro Dyno guy himself, Clement Chong:

this is a scary car, why!!

kanasaii!! THIS CAR IS SO SCARY UNTIL MY TWO NUTS NEARLY DROP OFF MY PANT.

guess how much the tuner want me to rev the car???
6000rpm... NO!
7000rpm... NO!
8000rpm... NO!
9000r...pm.... this is the max rpm range on the rpm meter....NO!
10000rpm...... you must be insane............NO!
i finally rev the car pass the 9000rpm mark and over the mark which has no more readindg and continue until about the 0rpm mark. walau A!!! i only show this type of engine in japan magazine many year ago and thats a SPOON for honda . scary neh!!! i rev it i think pass 11000rpm, i myself cant believe it, can you???

He was behind the wheel, while my friend Ricky was busy dialling in the tuning for the Hondata S300 via his laptop in the passenger seat. Though, my dyno session did came to an abrupt end following a bang complemented with a spectacular exhaust flame sprouting antic ~ did my engine blow up after repeated rev runs to stratospheric 11,000rpm?? Fortunately no, *phew!(in relief)* the upgraded valvetrain assemblies & strengthened block held its worth against the abuse. It was actually the stock ignition coils that got toasted on the last dyno run... *now i know why modded hondas run pricey aftermarket ignition coils (MSD)* and that was the only extent of damage...

Here's a clip of one of the dyno runs

& the result which, i wasn't too enthusiastic about:

158.55whp @ 8,800rpm; 137.79 Nm (14.05kgm) @ 5,800rpm
~ which, translates to
193.35bhp & 168.04 Nm (17.14kgm) ~ estimated output at the crank / engine, assuming transmission loss of 18%.
Compared to the stock output of B16A 1.6 liter naturally aspirated engine on papers of 170bhp @ 8,200rpm & 157Nm (16kgm) ~ there are some considerable gains, but still leaves much to be desired as the current setup is supposedly capable of pushing over 200bhp at the crank.
The max torque figure isn't exactly impressive too, although it is quite close to the mark of a 1.8liter B18C GSR. There's an apparent torque dip around 4,400 to 5,200rpm that needs to be remedied with further tweaking. *may be running slightly higher profile tyres of 195/55/15 compared to the standard 195/50/15 does play a bit of reducing factor in the torque output to the ground*
The hp curve towards the higher rpm range is expected to spike higher, but it could be due to my current setup not giving sufficiently high (crazy high like 11.6 or higher) to fully capitalize on the potential gain of the hi-cams... currently in the progress of addressing this compression issue, hopefully it will net more gain to achieve 170whp on the next run.
Since the peak power has been shifted upwards to almost 9,000rpm, the B16A stock, & relatively long gear ratios (compared to aftermarket gear ratios la..) will make it a little tricky to keep up & stay in the powerband when shifting gears. In short, the real sweat-in-pants action only happens beyond the 7,000rpm & it literally it takes ages for the rpm needle to swoop past that magical mark with my current gear ratio!! After all, how much horses your engine makes should take a backseat to how much horses your car can effectively put to the ground... *the gear ratios surely determines how the power gets delivered to the ground, but i'm not sure to what extent it will affect the max hp output as well??
From the low to mid range, the power delivery feels a bit flat (& torque-less too, ~ inherent characteristics of small naturally aspirated engines; the mantra "there is no replacement for displacement" reigns here). Maybe i felt it increasingly so, coz i drove it right after i took Ricky's impressive 211whp & 233Nm FD2R for a spin... xp


Among the other 2 Hondas on dyno that afternoon was Ricky's K20A FD2R (superb output !) & another Steven's NA1 NSX which netted 218whp & a whooping 300Nm!

I just had to settle being the slow-poke for that day.... Until the next dyno run....

Pasar Tamu thru 50mm

From Miri

Tagged along with my good photo kakis in Miri ~ Micheal & Unker David for photoshoot at Pasar Tamu Saberkas yesterday evening. I have never actually participated in a full-fledged street photography; i thought i would be really to be whisking out a big camera & start snapping pictures like a paparazi in a local market ~ imagine getting awkward stares from the people around... well, not unless i'm a tourist in a foreign land. Thanks to Unker David's impressive PR skills in getting the stall owners to warm up to the idea of having their photographs taken, of them doing their routines ~ first, he made his round, generously handing out prints of the photos he's shot there the week before to the respective stall owners who pleasantly suprised by the gesture... to which they responded by eagerly accommodating our photography antics =)
Unker David mentioned that his mom used to be a market kuih seller for many years but never had any photograph of her taken.... now this is something very meaningful
~ to have a candid snapshot of us in our working heydays to fondly reflect on, later in our golden years.
For the full set of photos, please visit my FB album link HERE.
Props to Unker David for the great shoot, & Mike too for extending the invitation! *i owe u guys a couple of PS tutorials... hehe =p

Project MG Exia ~ Completed!

I'm finally back in the business again after a month long hiatus; to my Gunpla followers, sorry for the long wait. Here are snapshots of my recently completed MG Exia:

I'd rank it as the 2nd best looking Gundam in my humble collection after MG Strike Freedom Gundam
