Typical Ah Heng’s Mojo

You see, I was only supposed to fetch the Pocong this morning and enroute for slaving activity on this non-working day. But it turns out I had to spend the entire day at Ah Heng’s for his team to complete the work and troubleshoot issues of the new add-ons. Yet, I’ve no regrets because it was worth in the end.

And I won’t beat around the bushes anymore so here’s the list:-
1. Custom FMIC – Used Evo3 intercooler, all-new custom piping from turbo to intercooler and intercooler to manifold, plus relocation of DV.
2. Open-pod K&N filter with custom heat-shield.
3. Custom 2.5” catless downpipe.

Yup, typical Ah Heng and his crew mojo, awesome touches on every single thing making what I’ve paid twice the bargain! No kidding! As for the drives, well, what I can tell though there’s a slight (very slight) lag of 300-500rpm for the turbo to spools but once the revs past 3k all the way to 5.5k, the car pulls with fatter torque figures and more rush feeling at high revs. I just can’t wait to get the whole thing settled down and visit GT for another dyno exercise :)

2.5" downpipe locked and loaded on Friday

It's as noisy as stock so no complains...

Some adjustment on the inlet/outlet needed, if Evo 7/8 intercooler of the same size, it would be ideal

80% of the job completed on Saturday morning

AH relocated the DV to the front-left of the engine bay for more cooling

Amazing work on custom heatshield

The old Evo 3 intercooler seems to be working well which defies its age

AH managed to make a hole when I didn't think it can be done

Got to love the welds done by the Myanmar national staff, reminding me of seeing these things in the US

Pocong full of blues hahaha

Initially I couldn't flat on the throttle because they've forgotten to include the boost sensor but all is well :)

Tadaa...

Yup, the Pocong dah merajuk!

Just two days after having test driven the Megane RenaultSport 250 Cup, the Pocong has started to merajuk! It was last Monday morning when the weather was raining, this car decided to throw overheating tantrum by twisting its radiator fan to pieces. I was left without a choice but to wait for some hours for the car to cool down before cruising at crawling pace towards Alex’s Ever Auto. Luckily, upon checking, the cylinder head and gasket are all ok hence I ‘only’ need to fork out almost RM1k just for that. And while at it, all major service essentials like timing belt, tensioner, water pump, fluids which resulted in RM2630 bill. Yeah that’s the price I had to pay this morning and following are the detailed breakdowns:-

Engine Oil: Q8 Formula Excel 5W-40 RM195.00

Oil Filter: VW 1.8T (06A 115 561 B) RM35.00
Spark Plug: NGK Platinum V-Power BKR7E (Own - RM50.00)
Fuel Filter: VW 1.8T (6Q0201051J) (Own RM48.00)
Air Cond Filter: VW 1.8T (1J0819644A) (Own RM70.00)
Timing Belt: VW BJX 1.8T (06B198480) RM195.00
Timing Tensioner: VW BJX 1.8T (06B198480) RM325.00
Water Pump: VW BJX 1.8T (06A121012G) RM550.00
Auxiliary Fan Assembly: VW BJX 1.8T (6X0959455F) RM850.00
Coolant: G12+ (2 bottles) RM90.00
Labour: Rectify front left door rattling RM75.00
Labour: Timing belt change RM230.00
Labour: Auxiliary Fan Assembly change RM75.00
Service Tax RM20.00

Total RM2640
And upon collecting it, I handed it over to Ah Heng for some essential upgrades which will help it the car to be more ‘cool’ and breathier than now. God willing, it’ll be ready in 3 more days provided he can work his magic party peace asap :)


The radiator fan somehow seized to perform harakiri on me

Ah Heng's boys started to do their job

I guess you know what will be sitting in between the crossbar and radiator/condenser :p

Too big!!

Mégane Renaultsport 250 Cup – You've just messed up my mind!

Judging from many months of sabbatical leave of absentees here, some of you might have thought that this blog is going to rot in the blogger.com hosting facility. Well, while I can’t deny it has gotten rusty around the edges and I can’t help but to use cliché excuse of work commitments which partly comes with a hell of a nightmare in getting ArcGIS software to work in an clustered Solaris zone which I would say the OS behaving like an 100 year old senile old man. And for a fact, I’m still working to sort it out …. with a sledgehammer soon!

Having slept last night at 4.00 am and woke up at 6.30 am (to send wifey for hemodialysis treatment), it’s almost like ordinary F1 GP live telecast time. That’s just not enough time at to have a short dreaming exercise. Radioactively speaking, this has somehow short circuited my daily SOP whereby for the first time in my life, I had a big mug-sized brewed black coffee in PMC to stay up which I haven’t had any before. And I also just had a different perception on a car I initially thought as overhyped. And my fellow blogger Azmir’s latest posting does pour something in the caffeine that stimulates me in getting interested in asking for a test drive.

And because PMC was nearer to PJ, on the way home, I told wifey that I want to take a slight detour to PJ to stroll back some memory lanes with an intention of dropping by a place carrying an address of No. 5 Jalan Semangat. The Renault showroom. Upon walking to the showroom, I was warmly greeted by a guy named Amos who brilliantly manages to make me feels at home in there even though I was donning a VW GTI t-shirt with French cars prejudice tattooed in my forehead. This I can explain.

You see, I’m coming from over the years witnesses pretty much of horror experiences from my relatives who own Frenchies among which:-
1) A clutch assembly decided to disintegrate itself from my uncle Citroen BX while I riding it to cross Johor-Singapore border.
2) The very same car has appetite in leaking its hydraulic suspension lines, any new replacement will only be leaking the following months after.
3) My grandpa’s then ancient Mk3 Cortina has better reliability than his another always sick Peugeot 305
who ends up staying at workshop than at home; and {the best of the lots}
4) My cousin’s Renault Mégane decided to auto pilot itself after cranking up the engine even the gear lever still at P. That was in UK.
Not that I’ve anything against Frenchies owners out there but hmm yeah, now you can see why I always stay away from it…….

Now however, the introduction of the new Mégane Renaultsport 250 Cup has started to get many chuckleheads throwing away Evos, Scubbies, Type Rs and GTIs for this striking and flowing hot hatch as their preferred sunday drive weapon of choice. And that has irked me a little considering from thick skull of mine, Frenchies comes with preloaded disintegration package for free of charge.

Gone by the days of the R26R was packaged with somewhat no holds barred, stripped out, anything other than air-cond being considered as luxury add-on with its sole party piece was all about thrills. Now, I feel Renault has modified the sporty Mégane’s angle of attack, nosed it a fraction towards the mainstream led by the mk6 Golf GTI, the hot hatch class seems intent on becoming all things to all drivers, with cars so polished that much of the texture has been worn away on concentrated Clorox formula inside out.

Sitting on my wish-list 6-way adjustable Recaro hugged seat with the engine on, I had to spend ¾ of an hour with Amos to understand how the electronic appliances, from radio, pedal cartography, digital gauge, g-nometer and main control console which resemblance a mini Gran Tourismo gadgetries of the CBR35. On the Godzilla, it’s ok but on the Frenchies, my gut feeling would say it ‘might’ just break after minutes driving out of the showroom. Again, I’ve let the prejudice got the ahead of me. But unlike the ubber reliable run-of-the-mill Golf GTI, this Megane has 6-speed manual box with mechanical LSD harnessing 250 odd horsepower from 4 potter 2.0 turbo engine upfront. A recipe that resembles a finely crafted mechanical watch which every tick gives a sense of bonding not some Playstation joystick.

Having said that, it’s a good thing that I can grasp how to alter throttle mapping from “Progressive” to the very “Extreme” on-the-fly before starting giving the car a good spanking towards Hartamas and back using E23 highway. To kick start this test drive session, I opted for “Linear” as I was told the delivery is ‘pretty brutal’. Check on that and next. The first impression upon getting the 18” matte black wheels rolling was the short-pressed clutch bites sharp and early; and the gearchange kind of stubborn to cog which some might struggles for balance a bit.

Going for ‘town’ drive towards Jalan Sultan Abu Bakar proved to be a little compromise. Having played back and forth from “Progressive” till “Sport” every hundreds of meters, the power delivery is very docile and very smooth with very much NA philosophy than outright forced fed stuff. And of course, typical French, on the rough surface and potholes, the Mégane is perhaps even more impressive. Never once being crude and frantic like typical JDMs and MCS, it soaks everything with 235/40/18 rubbers in its stride, utterly unruffled by quick progress. On the other hand, the clutch’s bite couple with the ‘need’ to swap cogs in between revs often might give daily driving especially on start-stop traffic something to think about. Nevertheless, those who’re used to aftermarket super single clutch will probably say it’s still a friendly puppy. 

With all that sober driving, the car stops at a traffic light junction besides Phileo Damansara with what separating me and E23 was less than 50 meters. Having ‘mastered’ the right hander scrolling technique, I opted for “Extreme” and began counting the moment to let it rip just a little bit.

Green pops up, immediately dumped the clutch, short shift to 2nd somewhere at 3k rpm, then only flat 2nd and 3rd at 4.5k rpm with gearchange started to show its true colour of giving satisfaction rowing through the cogs with precision but something has left me somewhat a little bit flabbergasted at first. Make no mistake this car is rapid and ubber responsive and smooth to an extend it doesn’t feel the G-excitement we normally get from force fed, in fact the meager chipped Polo GTI has more of that at midrange.

Decided to give another poke, I headed towards second part of the E23 towards Hartamas for another go. Flat 3rd till 5th, once you go past 4.5k all the way till 6.5k rpm, that’s where the 250 horsies comes to play ball nudging 200kmh on a short stretch before pestering after road hoggers. That’s what I call power! Combining with well stacked ratios of the 6-speeder, I’m not surprise if it can keep up with the 300bhp Focus RS at that range. So in terms of power, though not brilliant but that’s a check alright.

Moving on to dynamics, well honestly, I would prefer to have a nice flowing Ulu Yam to endorse but today’s session is good enough to note that it has most immediate, crispiest and very well weighted steering feel of all hot hatch I’ve ever driven yet. And even though it has close to 1400 kg of weight, going through rapid lane changes didn’t indicate it any heavier than the 1200 kg Pocong. To further add some spice, I flat it on a right hander just after Royal Selangor Club at 170ish, you know what, it just glided effortlessly and remains planted with a little bit of hint of its tail getting excited on slight liftoff courtesy of slower car going into the fast lane. If I want to be a bit more picky, I would say steering a little bit ‘numb’ at 15-20 deg of initial steering movement but then again so to all fwd cars. If this car were to let rip in Ulu Yam, it would be very very hard for many to keep up much less to overtake!

At this moment on, I’m left with a conclusion that no matter how much mods and fine-tuning on the Pocong’s suspension, it will never ever be as good as this Megane. And this has messed up my mind a little bit. Considering the price of RM228k which is steep I can deny, but given the ‘GT3’-like driving experience and mouthwatering pace on straights and curves, it make perfect sense for anyone having enough dough to buy this. Should I get one of these, it's going to don the colour of Oyster Grey with maybe the powder coating the wheels to bronze. Power upgrade might be inevitable and stock exhaust has got to be ‘upgraded’ for more rotty and pop character but suspension and brakes would stay stock. And I would name the car as Langsuir where unlike stock Polo hops in between, this car just serenely and goosebumply glides! :)

Sorry folks, I'm not being a fan of yellow. Oyster Grey is more stealthy!

The best place to look at this Megane imho

Journey in meddling with Car Dynamics

Words like control, response, precise, grip etc. are …yeah… very much cliché whenever some blokes blabbering on car handling. But it is undoubtedly the key ingredient in making driving enjoyable enabling you to grin from ear-to-ear as you kiss the apexes after another. And I believe in that absolutely 100x100% before tax and excise duty.

My yuppie driving days started with the Waja, Satria GTi and now coming to 3 years of ownership, the Pocong (Polo GTI), I’ve always trying to meddle with things to get the word like responsive, precise, tenaciously grippy, and adjustable on the limits to be associated with these cars. Because having mediocre technically sounds, things I meddled doesn’t always ended up to be rosy as hoped. Nevertheless, trial & error exercise is a good thing to know which worked and which won’t.

I can still remember the first time I drove the Polo GTI. It was torquey little car courtesy of the ancient but potentially potent VAG 1.8T. But I suspect things just got half cooked plus trigger happy VAG cost cutting exercises, the car’s achilles heels are in the dynamics department. On stock form, it drives with reasonable feel from the steering (mimicking Mk1 Golf GTI which my parent used to own two decades back), city car nippy through the turns and very adjustable on the limits which I love very much. Ok that’s the brownies but now is the BUT part.

At high speeds, it’s just frantically nervous upon lane changes hence the main reason I named the car as Pocong, it doesn’t glide but it HOPS! Reasonable feel doesn’t mean precise or responsive, that’s what the steering feels, and in today’s hot hatch world, it falls back on the loathering line of the people’s mind. And when I had it reflashed for more grunt, Ulu Yam is a scary place to be because it shows how mad it behaves. I had lots and lots of goose bumps as I prayed it didn’t hops or hell somersault into the ravine should things goes south and thanks to stock brakes I always have to second guess whether I can brake on time not to kiss lorries upfront. I even took it to the no nonsense place – SIC. It was worst! But I knew it has the chassis that is good enough to be explored, that’s where the ‘what if change this’ wish lists went on like a disease rotten up my mind and my pocket.

The first thing I did was to replace the stock spring with H&R’s. Cosmetically, it lowers the car by about 30-35mm from stock 9N3 Polo. That’s good. With lower CoG and less axis movement, the car corners flatter, more rapid and precise through the turns just like a normal run-of-the-mill hot hatch is supposed to be. Although H&R’s is progressive by characteristics, because its shorter and stiffer spring rate, it doesn’t gels well with the stock dampers. That’s where it rides noticeably choppy on uneven highways.

Second on the list was the braking. Audi TT’s 312mmx25mm vented solid rotors with ATE 54mm single potter plus steel braided lines brings more stopping power especially from 200+ kmh. Even if the car punches out 200whp, it should do fairly well in assuring me not to kiss cars upfront. Higher temp pads and heavy duty slotted rotors would be a big plus on further complementing this setup. The only gripe for me is the rear. At 232mm diameter, it looks horribly pussy.

Other things like Seat Ibiza’s solid rubber bushings on the front wishbones build up on more solidity feel in nursing the trigger happy torque steer coming from 253nm flat from 3,000-5,00rpm. And more impressive is the Federal 595 RSR. Who would have thought that someone from Taiwan can make good tyres. It’s like this thing has gotten a great spell by the great Merlin in masking Pocong’s achilles heels by instilling very direct response from the steering and provide very very tenacious grips. Throughout my stint with these tyres, I’ve never been in overcooked situation on sunday drives. In fact the more it loosen the thread, the more grip it gives unlike AD07 I heard.

When the car’s mileage went up to 60k kms, I was short on cash for H&R coilovers and reluctantly ended up with SuperSport. It was the cheapest dampers I managed to get hold on to at €200 including shipping. That’s 50% cheaper than originals. What I didn’t know is it does its job unexpectedly well even compared to Koni yellows/Biestein B8. It rides with more immediate feedback through the steering, it corners flatter and cover more ground in terms of lateral grip with more fluidity rather than outright harshness. And speaking of fluidity, I sense that the SuperSport dampers give much more composure dealing with uneven and bumpy roads which means I don’t need to slow down to readjust the music volume and my wife shouldn’t get sick every time traveling on long distance. Well that’s until I ruined it when upsizing the wheels.

I’ve always wanted to copycat Mini Cooper S’s wider chassis allowing the ability to mesh the juice from the engine and it should stick to the road ala AWD rally machines hence the reason why I wanted to upsize the wheels. In doing so, I’ve to admit, this has ruined the ride fluidity, fuel mileage and much more damage on the credit card. But in essence, it does resulting in wider track, it corners with lesser flexes and this setup serves as a good foundation for more lateral grip once I ditch the ‘geli’ RE001 for RSR. Not now but soon.

With all that in place, I’m very much content with the car’s dynamic behaviour on the winding road and it’s ‘liveable’ on day-to-day driveability. Now, it gives MCS-like chunkability when approaching corners, good steering feel and covers more ground in terms of the lateral grip (would be even better with RSR soon). And yet this still retains the adjustability on the limit characteristics in which saves the car few times from t-boning the lamp posts as it tail out at speeds. Having done some joint exercise with friends on sunday mornings, I could sense that the car should be able to smell FD2R’s exhaust fumes on medium-high sweepers of Ulu Yam without being left out too far behind. That’s good enough in my mind as FD2R is a legend precision tool on that area of expertise.

The only problem is to get the power down cleanly on tight sequence of corners like Batang Kali to Genting uphill stretch. That’s where it couldn’t tight up its engine gut to defy the laws of physics unless of course LSD fitted. Second thing is I need to find ways to soothing the mid-corner braking reaction where it just wants to dance, great feeling but can get me a little off-guard. Hmmm…having thing long and hard, should I want to go further on this car dynamics subjects, it would be these things on my mind:

1. Heavy duty solid rubber or PU bushes on rear axle beam, rear spring perch, ARBs.
2. H&R monotube coilovers and get tuned by someone who obviously know what he’s doing and that would NOT be me.
3. H&R ARB 26mm front and 28mm rear.
4. VF Engineering End Links.
5. Wierchers CF struts bars.
6. Peloquin or Quaife LSD with automatic torque biasing.

Hmmm going to have a very sweet and wet dreams tonight!

Journey on fine tuning the dynamics still far and away...

Thanks to Mugil, I've learnt a thing or two on SIC

Alcantara

This is something worth salivating after…hmm alcantara-ing the steering, dashboard and centre console; easily make the car a serious gym machine for sunday drives and track day. Can’t wait till the hire-purchase loan come to an end so that I can do something like this without flinching…

67.5k kms service

I just sent Pocong for a schedule 67.5k kms oil change at my regular place today. So happen that they run out of stock of Castrol Edge 10w40, I decided to have a go on Liqui Moly Synthetic High Tech 5w40 which is about the same price RM218. Everything went normal except the mechanic pointed me that FL top mount’s nuts (yeah all three of them) are loose …. really loose… like I can unscrew using my bare hand with zero effort! Luckily there’s no damage spotted. Can’t believe I went for 4-5 sunday drives with loose nuts … I was nuts to do that!

Just another day of TLC-ing the Pocong

I was told it's a good oil, let's see how it performs at upcoming GTJ
