Dear azzkkr2600 (ronn):

Sir Great Pics!

I am trying to get in touch with Rico Colayco - I hope they still have the book, keep your fingers crossed!

Ok - for those who wish to order filters, please bring a sample and the cash for the filters - will bring it to you next EB.

To those who drove my pickup:

Guys - there is a misunderstanding - the Alcohol Injection was NOT ON during your test drives!!!

The switch for the Alcohol injection is in the upper left part of the dashboard and the computer box beside the steering wheel will light up like a Christmas tree when turned on.

All that performance was just the engine tuning and the diesel fuel additive.

Remember get the basics right and use the additive and your truck should perform similarly.

I'm actually disappointed with the Alcohol injection - I need to run nearly pure methanol (expensive) to get results.

BTW I filled up with Total diesel fuel (and additive) just after our EB - I'm getting about 11.5 - 12 km/liter city driving kasama na hataw natin.

Not bad if I do say so myself.

Dear muneng:

Nice Pick-UP!!! Magpapalit ka ba ng makina? If I were you, dun na ako sa WLT-31 kaysa RF - balita ko di hamak na mas malakas siya na makina.

Dear pump_mann:

Welcome to our thread! Great to have you on board.

Sir, your suspicions are correct, the standard tires are 215 R/70 14 not 15. The bigger tire will cost you some acceleration and performance.

As to the sluggish performance, try to get the basics right first.

1) Replace the air filter, oil filter and fuel filter with every oil change. Clean the air filter every 1000 km (or less depending on conditions).

2) Change oil with a good oil, every 5000 km - any oil rated SAE 15W-40 and API CI or higher is a good oil.

3) Make sure you have no air leaks or water in the fuel lines.

4) Have a trusted calibration specialist clean out the filter on the injection pump (if you don't know how to do this yourself) and check the pump.

5) Make sure your valves are adjusted properly, your tires have the right pressure and your wheels are aligned.

6) As to the exhaust pipe size - is your engine turbo or non-turbo (like mine)? If non-turbo, 2.0 inches (ID) is enough, if turbo use 2.5 inches (ID).

A lot of people are too enthusiastic and oversize the exhaust system - this is worse for a gas vs a diesel engine, keep to those sizes and a good muffler - the 'turbo' muffler is a good design.

Too large and free-flowing an exhaust pipe and system will remove your low-end torque and kill your fuel economy - No Good for a work truck.

Balance is the keyword in exhaust systems.

If all of the above does not fix your hard starting replace your glow plugs.

Hope this helps.

Regards,

Dusky Lim

use semi-synthetic motor oil and VIC oil filters (these don't crack/break). if you currently have 15" wheels, just get 215/75 tires. it should increase the truck's acceleration -- or stick with the 235/75 with 15x7 rims for looks. i'm using 31x10.5 MT+ tires though. hehe.

do not forget engine/water temp too as it affects your trucks performance. use only distilled water (absolute or wilkins) and a bottle of shell coolant. replace every 6 months-1year.

transmission and rear axle oils? yes, these also need to be replaced every year or two or depending on the manufacturer's standards. since our trucks are more than 10years old, i guess it's better to have frequent fluid changes. SAE90 oil is cheap anyway. we only need 2 litres for the rear axle and 7 (to 12 for 4wd) litres for the transmission.

thanks for the very informative reply!

every time i buy a 2nd hand car, even though the seller will tell me the vehicle just got an oil change, i always have all the fluids changed ang replace all the filters. i had the mistake of buying a Mobile1 mono grade oil, but next time ill but a semi-synthetic one.

i did have the fuel system bled, but i still have yet to have the injection pump checked by my suking tayer. ill have this done together with the valve adjustment on the next oil change.

its a B2200 NA, so i guess a 2 in pipe would do.

sir, regarding the pipes, when ill have them changed it is still ok to use the stock primary and secondary muff?

also, regarding the speed, with the 235/70/15 tires and current hard cold start problem, my top speed was only 90kph with my pedal to the metal, is this normal or should it be higher?

thanks!
