d4d more power.

**jrn29** · May 30th, 2013 01:31 PM

^ yun nga kaya gusto ko sana ,madagdagan ng power lalo na sa acceleration. at kung sa top speed din sana kahit 10-15kph , mataas palagi ang rpm kahit nasa 100kph pa lang , mataas din sa kasi FC yun .. medyo kulang sa duluhan ang takbo ng m/t 2.5 d4d parang nang hihingi pa ng kambyo .kasi ang mga a/t naman ang mababa ang rpm kahit nasa 160kph na .

i try blanking plates and k&n air filter muna bago yung race chip, obserbahan ko muna

i was able to drive an innova 2.5 d4d j when my friend bought one, 1st gear acceleration was fast as if parang gas engine lang but pag dating sa 2 and 3 medyo mabagal mag accelerate but you will notice it has a lot of torque which is the norm for a diesel engine, but compared to old school diesel it's a leap beyond.

in my opinion nasa driver siguro yan kung gamay na niya yung auto, cause my friend who own that innova, he's usual cruising highway speed is 150kph -170kph and in the city way above the normal driving limit (never rode with him again)

The 2KD-FTV gets you to decent speeds faster than the VVTi without really pushing it. Yun nga lang wala masyadong top speed.

Parang contradicting paps, kasi it will be impossible for a D4D innova to get into a decent speed faster than a VVTi, kung from stop, I will agree, but kung parehas nakabwelo, it will be impossible. Mababa ang rpm ng diesel engines so it will require more time para makaipon ng enough energy to gain speed.

may limit ang speed ng M/T na innova, hanggang 165kph lang ang top speed.at kapag lumapagpas na ng 120kph masyado ng mataas ang rpm nito. kaya nga mas mainam kung i mod ang d4d madagdagan na din ng top speed kahit 10-15kph para kahit nasa high speed ka , mababa kahit papaano ang rpm , para tipid sa diesel .

You cannot change top speed without changing the rpm, for the rpm to remain constant and you want a change in speed, change your differential gear box.

RPM is directly proportional sa speed in every gear ( 1st, 2nd, 3rd..), so if you want to change your top speed, it means red line speed, change your gear box.

Btw, I am talking here in ideal conditions, ie. negligible wind drag, flat straight road.. etc.. or sa isang salita sa speedtest laboratories.

^Yeah, it's the gearing that determines the rpm at a certain speed. One way around it is to place larger diameter tires.

A stock Innova D4d m/t will be hard pressed to hit 160kph on a flat road. I wouldnt even think much of running at that speed either; 120-140kph is pretty much good enough for those open stretches so it's really the acceleration/passing power where it would be best to improve on when you go into doing mods.

You are probably right. I did 140kph at sctex on my mt d4d and odo is almost at 4K rpm.

Wilcat is probably talking about accelerating from stop as you mentioned. D4D is also better at doing overtaking at lower speeds because of its higher torque than the vvti. I experienced this myself when I travelled to isabela on two close occassions using a vvti rental innova and my d4d. A chip mod would probably be a good idea for a little more umphh.

**siopaonatoasted** · May 31st, 2013 08:00 PM

I cannot contradict your statement as I have no experience with a D4D engine.

Yung masishare ko lang is yung experience ko with the VVTi compare with a regular diesel engine like 2C, pero dahil nakasakay na rin ako sa landcruiser, wala binatbat VVTi sa hatak ng landcruiser hehehe... Joke lang sa pagcompare ko ng dalawa..

**jrn29** · June 1st, 2013 03:24 AM

ah akala ko kasi, magbabawas ng rpm , nag research ako effective daw talaga yung mga chip na i-install ,may napag tanungan din ako dati nadagdagan daw ng 10kph ang top speed niya sa innova niya

ito nakita ko sa diesel tuning philippines, medyo pricey nga lang

Stock horsepower :102HP

Tuned horsepower : 167HP

Stock Tourqe : 260NM

Tuned Torque : 380NM
