nitrous oxide boost

[charlietuned]

Hi ,,
I am the proud owner of a 1999 Toyota hilux twin cab with a standard [Long] bak on the back , It has the naturally aspirated 3 litre motor [the 5L] When I first bought her I was driving a 3 litre Ford bakkie and got very frustrated by the lack of power from the Hilux , I wrote about it on this forum and the chaps on the forum convinced me to rather learn to live with the motor as she is. I have lived like that for a few years now ,but am still frustrated by not being able to overtake a slower vehicle on an uphill, she just looses too much speed because of the lack of power, It actually sometimes becomes a bit dangerous!!. A friend and myself were coming back from Jefferies bay Yesterday and were discussing the viability of using nitrous oxide boost , for just a little extra overtaking ability only when needed, i am not looking for masses of power and eccelleration, just a slightly bigger safety margin . Kits are available for that , but , why I am writing on this forum is to find out if anybody has done the conversion , and what people think of the idea
PLEASE let me know
thanks
Charlie

The quickest way to break a motor is to use Nitrous Oxide, the sudden extra strain on all the internal moving parts is too much and you usually break a piston or bearing.
I would not recommend it, as the nitrous is not to be used when the motor is already under a big load, like over taking on an uphill.

Drag cars use nitrous, but they are racing down a level road, they have also built the motor to take the extra strain, and if you chat to anyone using nitrous, in the end, the motor breaks

Don't like the idea of using nitrous either. Rather look at other options. Maybe fit a KZTE motor. What tyre size are you using?

it sounds quite funny, but i had always wondered about the use of that quick application of extra power only when needed and wanted to once ask about the possibility of using a 300bar dive cylinder linked up to the intake somehow and get a little forced induction somehow from the compressed air, like you said, only when needed, I just wasn't sure if it would even make a noticeable difference though. the only thing that would bug me would be the idea of a permanent cylinder in the car somewhere which might always get in the way.

Bear in mind that a properly installed nitrous kit also adds extra fuel to keep the mixture correct, if you just add extra air you will run lean and break the motor even sooner.

[Sven]

to be honest i wasn't really wondering to much about increasing pressure the same way a turbo does, more along the lines of helping the engine out a little so it doesn't need to work as hard to suck in the normal air, so the carb would still correct the air fuel mixture. but wasn't to sure if it was even a possibility. and the thought of a pressurized tank in the car 365 days of the year is a pretty cuck one. ha ha.

Nitrous does work when done properly with a proper controller and preferably linked to the ECU to pick up WOT. It's these badly done installations or user error that puts pistons through the block. With that said only a certain shot of nitrous can be used on stock internals because the 75kw+ (or more) gain might be a bit much for some motors

Everyone I know that ever had a nitrous kit (myself included), sooner or later, broke the motor, even installed by a reputable tuner with a Unichip controlling it all.

IMHO its really not worth the gamble

Unfortunately it is never that simple. Nitrous is a bad idea unless you want to be rebuilding engines every so often and sadly there is no simple solution. That engine was designed with a specific output and the moment you start increasing performance on that engine it comes at a price. Fuel consumption and reliability. There is no such thing as a free lunch. The easiest way to improve performance on a diesel is to increase the amount of diesel injected. Other than with a petrol engine a richer mixture means hotter ignition temperatures and higher EGTs as a consequence. You want to increase power at the worst possible time for the engine i.e. At the time when it is labouring the most and you are going to get the biggest increase in temperature.

My best advice is to make sure that the engine is well maintained and in the best state of tune possible. I.e. Clean filters etc.

If you really want more power consider an engine transplant. The 2.5 mazda/ford engine comes to mind. Ideally a 3lt D4D would be the best and most expensive.

Driving a diesel is an art, and a lifestyle..

You need to know when to hold them.
Know when to fold 'em.
Know when to walk away.
Know when to run.....

And have the right gear selections for each of those way in advance. If you are going to rush a diesel you are going to break it.. guaranteed!! So my advice is to relax, take it as it comes and live with it... or go and buy a petrol engine vehicle.

...or get a proper diesel motor and kick ass, "Petrol is so last century"
