My FC Getting Better With Low RPM

[iagree]

Hello guys,

Last Sunday, when i drove back from Msia to JB 2ndlink to SG with 110km/h & 2000 to 2200RPM, my FC has increased back to 17.5km/L.

Song!

Regards.

reason : aerodynamics

That's very good fuel economy. 

What's your tyre pressure for front and rear tyres?

hi bro iagree, tot u r Mr Cheong lei.. . Must be damn sian rite!

Hi jazz, it's positive. Tried few times b4 in NSHW but can't hit anything near whenever in Sg...

[david1881]

maybe can get 20km/l if you travel 80km/h?   

[Jazz]

So maybe FC is for on traffic condition prior to our right footer then.

i think so...still finding the theory behind all the FC things..currently try to increase the tyre pressure to 250 and 235 (vs 240 and 220 b4) as recommended by bro fri13th and RG on another forum...Mine in Sg, so far can hit only 13km/l.

Hi LatioR,
Besides increase your tyre pressure, maybe you can try to make your car leaner or lighter.

done b4 by removing the bady seat weighted >7kgs to smaller one at <2kgs i guess...the FC has slightly improved after this. ====> Next Target, to reduce the driver weight which is ME lah...OK   currently at 75Kgs to 70kgs that will be great

my pressure is 245 and 235 for front and back tyres..

but will going up to 250 be dangerous?? less contact with the floor, skidding.. etc..

Defintiely more dangerous if increase tyre pressure...some more our latio CG very high...on wet or windy conditions road....becareful....also watch out for small deris on the road when driving with such high pressure tyres at high speed....a small stone or rock can send ur car spinning and skid....

please correct me but won't overinflating our tyres make our ride more bouncy thus decreasing ride comfort?

hee, now post also very stressful in case give wrong info

yes...the same analogy can be used on bicycle...if u pump ur bicycle tyre to very "full" (high pressure), it becomes more bouncy but less grip on the ground...tat is why usually those 4X4 off road vehicle has flatter tyres...to improve grip...but this also means more drag which translate into consuming more fuel....u have to see wat is ur tolerance for personal safety to personal bank account safety is....varies from person to person...

Why stressful? 

Overinflating your tyres also causes unever wear on your tyres. The centre of your tyres will wear out faster.

With less cushioning and shock absorbed from the tyres, your shocks also wear out faster to an extent.

Most important thing to note about overinflation of tyres is the safety aspect. It reduces the amount of contact your tyre has with the road, resulting in lesser grip when you need it most.

Like i mention in another thread, I hope TLC will remain friendly just like before, those who had also surf mycarforum will realise how unfriendly it is nowadays.

I think there must be some misunderstanding between you and some other bros, perhaps it will be good to tone down or maybe attend some meetups so that people will get to know you better thus diffussing the current situation.

I am sorry as I may not be the right person to say all these as I don't attend meet-ups myself.

The different opinion was a result of individual definition what is over-inflating. By car manufacturer recommendation or by tyre specification.
 
I agree there will be uneven wear due to non optimum setting for any product but we have to be practical. You notice the design different for car tyre and motorcycle tyre? The cross section shape is different. IMO, car tyre have ticker, harder and flatter rubber on the road contact side thus have the resistance to flex at that section that cause centre of your tyres wear out faster.
 
When you pump more or pump much less, you first notice the side wall change shape much obvious than the flat contact point right? Say the centre part will bulge and wear out to an extent, but by how much? Just look at your own old tyre when you change them. If centre part wears more, ok you really over-inflate; if side wear out more, ok you can pump more; if you still have thread all over, then don

Hehe....I dun attend meet-up also....actually, attended meet up in other internet forums many years ago...then found myself so out-of-place....somehow can't "talk" as freely as on forums....i guess it is the security of hiding behind my user names tat makes me open up more....hehe...

Actually, pumping more air is much safer than having not enough air. The common misconception that pump more air will lead ur tires to bulge is because last time tires were poorly designed. Now new tires have steel belts in them, so its perfectly ok to pump more air.

I pump 300 on all 4, and combined with slower driving at 90km/h, I achieve FC of 19+km/l constantly. There's other techniques as well though.

People often complained that my ride is  bumpy. Yeah, it is, but when I told them I'm getting 19km/l, they go "oooh". So its a matter of whether you want to ride comfortably or save money, and considering the roads in SG are already relatively smooth, I'd go with saving money anytime.
