Hilux 4x4 Forum

Hi all.

I have been looking to get a bit more bite from my 4.0l and the plans were
1. Chip. - Just not enough boost for the petrol
2. Super charger - To much of a modification and very expensive



And just as I wanted to give up

3. Turbo for my hilux.

From what my study has gathered
1. Driven by electric motor so no airflow mods needed
2. Can remove very easily when you sell your car and install on next car
3. 30% -40% increase in power and KW
4. Designed, tested and built for SA conditions
5. +- R18 000 installed and maybe cheaper with stronger rand.
6. Did test on my Lux and pushes more than enough fuel through for the extra boost
7. Patented unique design
8. Sole right to unit held by ex performance car technician. Been in business of Dino tuning for years.


I'm looking to see if the interest is there to run a test day.

ANYONE INTERESTED?

I wouldn't mind that at all

Any online info available for the unit?

We are working on a website and I'm meeting with the technician as soon as I'm back from Limpopo for test run.

The better description is that it is an Electric Turbo designed for naturally aspirated vehicles.

A car without turbo has a different compression ratio than one fitted with a turbo. how are you managing this? Is this unit not just a supercharger working of an electric motor rather than a turbo charger? Is the electric motor a variable speed driving unit or fixed speed?

MUST be variable speed - or it will need one mother of a blow off valve ....

and the speed at which it various the supply air volume must change FAST to keep up with the rev range en responsiveness of a petrol engine .... no use in gearing down if the electric pump is going to take a few seconds to wake up ....


I do believe this have been tried a few times.

Some very good reasons why so many mechanics still install turbos or blowers - both physically connected to the engine speed, or then at least to the volume of exhaust gasses in the case of a turbo ...

Compression ratios remain the same0.15 to 0.35

suppose you can call it an electric supercharger

I understand its connected to the pc box to regulate all you need.
There is some mapping involved as well.

Old school engines required you to drop the compression ration, on modern engines you can get away with it up to a point but I dont think the boost will be going to that territory where you will need to drop the compression ratio.

Which brings up the next point ... "turbo" vs "compressor" vs "Blower" vs "compensator" ...


This is starting to sound like a "compensator" ... offsetting low pressure high altitude, by providing a "bit of boost".

And the "similar compression" ratio seems to back this - though by definition compression ration is function of clearance volume to stroke volume, thus not a function of a turbo .... more correctly the increased air flow means more fuel can be burnt and more developed - thus more strain on the bearing surfaces. Again back to what older engines can tolerate vs newer engines .... Punch line - by adding "30 to 40%" to the power figures will certainly be pushing the limits of many engines ... But if this is only a low pressure compensator, then it will only be adding a small bit of power to that which the engine should have a coastal conditions ... well actually 25% increase to coastal conditions.


some of these figures dont seem to add up that nicely ...

would be interesting to see how this works in real life.

I hear you. Also looking forward to a test run. Seems like installation will be Thursday..............

I'm off to the farm first for some work. Will keep taps on the tread. Going to send all the questions to the technician as well.

My thoughts exactly.

This is just one of those posts that i have to follow...i'm keen.

Why has this been such a quiet subject?? Are those test still running?

Sorry, i have been stuck in musina with a contract and was never able to do the installation. It's still on the cards, for sure. Contract is done in October

Are you still planning on doing the installation? keep us updated...

Definitely planning on still doing it.

Any verdict....

There are allot of these type of videos on YouTube.

Mighty Car Mods did some tests so you don't have to :)

Here is the link:

Its a 4year old vid. Technology has come along way since then. I still have not been able to test. Just to busy at work. Will see how this week goes

Hi Stumps,

Have you ever had time to run those test...
