Hi All,

Just wondering if anyone has tried the Vaporate fuel saving system at Repco?

If so, what are your thoughts?

This is just the cynic in me, but as with all of these sorts of things, if it seems too good to be true, it usually is.

It doesn't seem to be in the same league as the fitch fuel catalyst or brock polariser though...

Cheers

They are all absolute rubbish, don't waste your time and money.

The Repco catalog has a disclaimer that states to some degree that all the statements about
vaporate is quoted from vaporate not Repco. So I think Repco is just selling it without any
tech knowledge and proper research.

Hey all, I work with Repco and this Vaporate is the real deal...im not just saying that, cause honestly i dont care how much money repco make lol. Repco put haeps of cash into this project (so they say) but anyways having experience with them in my 3.5l i do recomend them....no performance loss etc.

These look like they could work....it makes sense.

In another thread on here about the Vaporate, someone said that if they work so well, why arn't they standard issue on all new cars? That turned me off them, but then thought that they are a patented design, so carmakers can't use them without permission from Vaporate and some sort of hefty money deal.

I am still deciding on wether to invest in them or not....seeing as petrol is 139 in Victoria (bloody government pocketing 55c a litre).

And just to let people know, if anybody cares, my last total K's from a tank of Shell Optimax was 640 which I think is pretty good. Although my driving is 90% country road 10% town, and my driving style is pretty enthusiastic.

This is a hard one.

Its the marketing of a potentially bogus product vs the word of a 'professional' engineer who worked on such fantastic engine concepts, yet is now setting up EMSs for cars (hardly what you'd expect from someone with such indepth knowledge about engine design).

Hrmmm....
Do I believe the marketing, or the words of a self glorified engineer. No I think I'll wait until Today Tonight do a piece on it, they'd be equally as credible.

Until somebody does an indepth comparison of a before and after on a Magna (2.6, 3.0, 3.5 and the 3.8), the jury will be out. No doubt the fuel savings (if any) are VERY dependent on the setup of each and every engine. It would also depend on the state of the engine, clean injectors means better atomisation (I assume), and these things may onlg give better performance with injectors thats are clogged up.

As for not being standard, why does my car come with restrictive cast headers, and not some nice mandrel bent extractors? It's because theres always a tradeoff between COST, PRODUCIBILITY, RELIABILITY and DESIRABILITY vs PERFORMANCE.

Does heating the fuel via the injectors work?

The inventor agrees that it works better on some cars than others. It depends on the type of injector, how it's fitted and if sufficient heat can be transferred from the engine.

It generally works better at lower revs, at launch and is good in city traffic. It helps keep your fuel system clean and can gradually reduce carbon deposits, improving rough idle.

At $289 plus fitting it's a little expensive but fortunately the 3.0L & 3.5L Magna engine design is suitable for a better system that simply attaches to the fuel rails.

I have personally used this system for 6 Months on a TJ2 and notice improved throttle response from off-idle up to 3K RPM.

Fuel consumption remained at around 9.8L/100k in suburban driving.
At $45 plus GST & delivery for the basic kit ($109 + for a full kit for engines with EGR ) it is also compatiable with any CAI.
Let me know if you want one.

Yes but it works much better if its heated before entering the combustion chamber.

You get improved vapourisation whereas on a standard engine the higher the revs, the less time the fuel has to reach optimum temperature. There is also the benefit that the fuel expands and increases in volume slightly.

Note: The new 380 will reportedly have 12-hole injectors in order to improve vapourisation but they will probably never have additional vapourisation equipment due to the cost.

What do these kits contain?

Hi RuSSiaN

The Kits contains a full set of ferro-alloy heat inductors that easily attach to the front & rear fuel rails. It uses no power from the engine, instead it uses the excess heat from the engine to pre-heat the fuel and gain a better fuel burn.

i have seen a beefore an after wooh its mad if u ask me

Like those used to make the quick-thaw plates for thawing frozen meat? I should be able to
make a set from the one I got. :badgrin:

u no when u just tap the gas it cuts out it gets rid off that an gives u stacks more go

Which ones you talking about?

Not in a multi point EFI car it doesn't, the fuel enters the combustion chamber via the injector, not the intake valves, they only let in air. In a carby or throttle body injection (one injector), the fuel enters with the air past the intake valve.

That only happenes in direct injection engines, in standard EFI setups air/fuel is premixed just befoe the intake valves.
