high speed 4x4 (4H)

[mosso670]

My ride is strada 4x4 glsv mt*14000km.mga sir paki share sa mga experiences nyo using 4x4 at hi speed or 4hi..at ano ang speed limit ng 4hi. When to use 4h.in my experience when the road is wet madali mag spin ang rear wheel so i use 4h for safety.tnx in advance..

Sir mosso670,

GLS V MT here, Sa experience ko po using the 4H, kung sa speed, hindi sya nakakatulong, (dry and wet road testing) more on traction sya applicable, kung hindi basa kalsada, mabigat na yung steering, hapit na hapit yung gulong and very reactive na ang steering, then yung acceleration, Non-V na ang dating.

sa wet road condition naman, na test ko one time na mag-engage during high speed (80KPH at biglang umulan) almost the same din pag dry road, hapit din yung gulong, mas smooth pag tumakbo and no problem up to 100KPH,

Nasa manual po yan, activation ng 4H during driving (shift-on-fly) engage dapat before reaching 100KPH, kung low speed, papasok na yung 4H at 40KPH then kung medyo mabilis, 80KPH.

Sa strada ata is easy select, then sa montero naman, super select.

hindi applicable gamitin yung 4H for long period sa dry pavement sa easy select, (parang katumbas ng 4HLc sa super select)
applicable lang sa wet road condition at sand road condition. (part time 4wd) nasa 2H lang lagi

then sa super select, pwede gamitin yung 4H all the time either wet or dry road condition, yun lang, mas malakas ang FC saka yung wear and tear ng gulong.. (full time 4wd pag naka-engage na sa 4H)

kaya most of the time sa 2H lang lagi para FC efficient and gamitin lang if necessary required.

you can go upto 150kph on 4H safely

Same model tayo. First of all, it is not safe to drive fast on a wet road on a rainy day. Bear in-mind that our roads are not exactly even and there will always be some puddle of water pooling in certain areas of the road. Once you pass this puddle of water at high speed, there is no 4x4 technology that could prevent you from hydroplaning.
Yes 4H will provide better grip on wet but at the expense of fuel consumption. However I did enjoy the benefits of a 4H while driving high speed in a loose gravel/unpaved road in bukidnon Ma feel mo talaga gumegewang yung rears mo pag hindi ka naka 4H, lalo pag may malalim na lubak na madaanan or turning on curve part of the road. Feeling rally hahaha lalo na when you see dirts fly and clouds of dust behind you.
:bounceD:

Hi guys tanong ko lang, may 4wd warning light / icon ba sa instrument panel? wala kasi ako napapansin sa Mitsubishi 2008 4x4 gls at. hindi ko tuloy alam kung naka activate na ba ang 4wd. thanks

[mosso670]

Tnx mga bro for sharing your experiences using 4x4 at high speed.thumbs up!

[mosso670]

Yes sir meron.color green.

[vhyken]

Nagtataka lang bakit walang indicator sa instrument panel ko, blown fuse kaya?

Posible... Pero you should feel the difference in handling pag naka engage na yung 4wd di ba?

If you're going in a straight line, no.

You will only really notice if the roads are very slippery (in which case, you shouldn't be going anywhere near 150 km/h) or in very tight turns where you might experience wheel-binding.

4H should never be used at high speed or on a dry road, it's pretty bad for your tires.

[LN106G]

Also, using 4H on dry pavement will not only wear out your tires faster, but more importantly, your gears (the 4WD system that is) will bind or it will grind on itself.
If you want full control during high speed with twists and turns on dry or wet pavement, all-wheel drive is the way to go...

Sir niky & Sir LN106G,

Applicable lang po ito sa Part time 4wd? or even sa mga full time 4wd? sa super select po, pwede sa 2H at 4H, in dry road condition. (yun po ang nakalagay sa manual even dun sa sticker na nakadikit po sa gilid ng pinto sa driver seat)

Since under-used po yung sasakyan namin, minsan ginagamit ko po yung 4H, sa dry pavement para ma-lubricate yung gear sa transfer case, (80 KPH Max) then sa wet road condition naman, nasa 120KPH, in a short period of time. (5mins)

As mentioned above sir nakakasira daw ng gulong at drivetrain yang ganyan. Sa amin naman, ginagawa ko ineengage ko sometimes yung 4H or 4L dun sa part ng office parking namin na may gravel. Malapit na distance nga lang pero at least nagagamit yung 4X4... Hehehe..

The Strada uses a conventional 4wd system designed for use on surfaces with adequate slippage (loose surfaces, mud, slippery surfaces). Otherwise, 'binding' will occur and can damage the drivetrain.

The Montero Sport uses the Super Select system and can operate on paved roads in 4H because it has a viscous center differential to eliminate binding on dry surfaces.

Lock the center differential and it operates no differently from a conventional 4wd system.

Agree with Doc here. For the Mitsubishi Super Select system, 4H is different from 4HLc.

4H is "4WD, high range, viscous coupling, centre differential free for safe, highly stable driving on roads in virtually any conditions". 4HLc is "4WD, high range, centre differential locked for extra traction while traveling on rough roads or other low-grip surfaces at normal driving speeds".

Amen on this.

I have tried using the 4H on our Strada GLS Sport V on our way to Sorsogon last December. The steep and sharp twisties were a real proving ground for the car. It felt very much more planted and secure than in 2H mode. There seemed to be less body roll and corners were taken with confidence and poise. On the straights I was able to push it upto around 110km/h. Acceleration was definitely not as quick as in 2H. According to the MID, FC increased from around 9+km/L in 2H to around 7+km/L in 4H. Same driving style, in the twisties.

One word: Understeer.

Placebo effect lang yung handling.

Sir SiRbossR,

Correct me Sir if i'm wrong, Similar po ba sa "Pivot"? once na high speed straight pavement (dry) at biglang steer, even sa max steering angle, once na hindi po na hindi ma-correct by means of brake or slowing down? deretso po ba ito sa explain why?..

[niky]

If the Montero Sport is a viscous system and full-time, then there is no problem... as you can't switch to 2WD, anyway.

But such systems can still benefit from a 2H switch. The Nissan X-Trail comes with one, and that actually makes a huge difference in economy and power.

If there's less roll, then the car isn't cornering as hard. Hmmm... don't recall ever slaloming the Strada back-to-back in 4HI and 2HI... would be an interesting test.
