- Hilux Ute - Vs Ecotech Engine
For those that have seen my posts before - you will know that I have been pushing the Blos mixer pretty hard. I fitted one around 6 months ago & I have done over 20,000 klm so I thought it right to post what I have found.
I have three vehicles, two run Airod variable mixers & the third runs a Blos - all three ran std ring mixers originally - so I am in a pretty good position to see the differences all round. I tune all vehicles by reading the oxygen sensor & driving the vehicle.
The Airod is great for most vehicles - with a VS V6 std engine it runs like it was on petrol with a std dual map LPG / Petrol memcal. (With the std Mixer & petrol only memcal it was a pig to drive with a huge loss of power.) It doesn't affect revs at all & it will rev right out as if its on petrol. Though it does not give the right draw down low for easy starting.
The Blos is fitted to a 2002 2.0L 2wd Toyota Hilux - always carrying a load - minimum of around 500kg. Its fitted with twin LPG tanks with a useable 128L. I get a consistent 1000 klm's per 128 L on LPG which is combined highway / town (not city - I don't get stuck in traffic) this equates to around $80 per 1000 klm depending on the cost of the LPG at the time. I drive pretty sedately though but keep to & exceed the speed limit at times.
I have been recently driving my Mothers Mazda 2 which is a 1.5 L auto & it costs me around $60-70 per 500 Klm - so the Hilux is pretty cheap running cost especially considering the weight I carry all the time.
A std ring mixer will not give enough draw on the LPG at low revs & is a restriction at high revs whereas the Blos gives the LPG the RIGHT draw right across the rev range without being a restriction at high revs. This makes starting much easier & drive ability of the vehicle at low revs - high engine load especially considering I run the engine on the lean side of stoichiometric.
I believe its as good as vapor injection in drive ability & fuel economy - its far cheaper than Vapor / Liquid injection & I don't have the expense of computers / injectors failing at a later date - ultimately its easily adjustable & very reliable. I have not changed the mixtures at all since original setup. Obviously its not going to help people with later model vehicles that require Vapor injection to comply - it can easily be fitted with an LPG computer system though so as to comply with most vehicles emission requirements.
Its certainly something to consider for people wanting performance though after doing research on other systems including a GRA system. The Airod as most of you know is not produced anymore & the Blos is available on Ebay.
