LPG conversions,anyone own/converted their motor ?

had one quote this morning for £850 all in parts,fitting the lot - guy seemed pretty clued up to

Hmmm, anyone read the recent article on this in Car & Driver? They suggest it's not the wonder solution it's cracked up to be.

the way I've heard the Bio-Ethanol argument is that the US want to use big wodges of their spare land for growing the crops needed to produce it in large quantities... this will then shift the balance of power away from the middle east in terms of controlling fuel output, and mean the US get to set prices and decide who gets what.

personally, i keep out of the politics of it all, fill up with regular unleaded, grumble about the price a bit and keep on plodding along.

I read a little snippet in PPC on how LPG is the performance fuel of the future. Apparently works very well on High CR engines and produces more power than standard unleaded.

what's e85?? [/divvy]

I converted my Skoda Shop Hack 1.3L MPI east block to run on E85, just fitted a fuel pressure regulator on the return line from the injecion and turned it up to 4bar wich overrides the stock regulator set at 2bar, the milage went from 0.62 liter/10km to 0.95 liter/10km but with 13SEK / liter 95 octane versus 7SEK / liter E85 it works out quite good monney wise but there are not E85 pumps at every gas station, although they are growing in numbers. The car became real hard to start and in the winter it was impossible to drive on E85 and you had to go regular gas then so I gave up on it and live with the gas prizes and since it's quite good on gas I don't complain but when started it ran like a dream, much more pepp and felt overall more powerfull....

The Stripper RSV Mille R I'm building will run on E85 since it will only be used when it's warm and nice and another gain from running E85 is that the working temp on the motor is much lower and that way I can getaway with a 50% smaller radiator, this is a thing many Hot Rod builders here in Sweden has found out so you can slim down radiators and if you are supercharging you get some extra punch from running E85 and if you run a gaz guzzling supercharged big block the savings of running E85 versus gas is huge......

damn! my rg125 has chrome bores will it affect that too? i don't even know if it will work with a 2-stroke but it seem's i gotta try.

Running a 2-stroker on E85 is NOT a good plan, first of all regular 2-stroke oil will not mix with E85, you'll have to run verry expensive racing oils like Castrol 747 etc. Also you have to jet it up so much it will be verry hard to drive so E85 in a 2-stroker is not worth the effort, in a 4-stroker it's perfect.....

DP says: There's an E85 exposion going on over here, the best selling new car is the Saab E85 9/3.....

i all ready run all my 2-strokes on castrol tts

First of all I would never use TTS in a performance 2-stroker, it's not really up to it. I have had a major sesiure of a 2-stroker (on NOS) where even Castrol admitted to it beeing TTS that could not keep up with RPM's and heat bildup. The TTS will NOT work with E85 since it's a 85% alcohol & 15% gas mixture the only 2-stroke oils that will work with that ratio IS a castor based oil and with that wou'll not be able to use your oil injection, you have to mix it into the fuel or there will be NO oil film coating your motors insides......

DP says: Belive me on this we do some serious 2-stroke tuning at the shop and will ONLY use VP 108 octane.....

Winter in Sweden sucks badly!!!!!

has any 2stroke ever worked on NOS where was it injected in? <just curious>

You bet your ass!!!! I have 2-strokers on NOS for racing and daily drivers (kind of), the important part of running NOS on a 2-stroker is you must have fuel pressure so you must have a fuel pump fitted. On my racers I fitted fuel pumps that supports the gasoline side of the NOS setup. On the daily driver wich is an Aprilia SR50 DiTech, fuel injected 2-stroke moped scooter, the DiTech has a fuel pump that gives 8 bar pressure so to run NOS on that is childs play, on all the NOS 2-stroke setups I have done the Fogger is mounted in the intake between the carb and reed block and belive me it rocks!!!! Love to blow the doors of GTI's at red lights with a moped!!!!

what was the weather like when it got to hard to start the shop hack?

When it started to go down towards + 3-5 Celcius it was almost impossible to start without start gas (diesel start), between +10-5 it started but you had to grind it for a while and I could not get used to have to sit and grind the starter for a while all the time.....

DP says: NOS is one of my favorite drugs......

Indeed. The C&D article also made the point that the crop is fairly intensive in the amount of fuel it needed to grow, harvest, transport, refine etc.

so how long, realistically, before we can all get a sci-fi style waste disposal unit on the back of our cars to convert vegetable scraps, grass clippings and so on into fuel?
