All gassed up

Recent mods: new high flow thermostat, PERFECT! Warms up quick and stays warm, not hot.

Today I got the vette back after an LPG conversion. Pretty good, runs smoother than ever (although my carburretor did need rebuilding) There is less power, but I havent really tweaked anything yet, it doesnt want to shift up a gear when u floor it, so theres some stuff left to do yet. But otherwise, it doesnt smell, doesnt shake and its quieter (so whats the point your asking) well, today I topped up my 90 liter tank- 45liters and I handed over $15, thats nice.

Need to cheak out some better plugs, previous experience with Bosh super 4's run fantastic with gas.

I did it at The Gas Man in Alexandria, becasue JEff from our club did it there. Howevwer It didnt seem like they remebered anyway. Generally ok, but it felt a bit like that Sienfeld where there all waiting at the Chinese restraunt- "Oh, another 5-10 mins..." it was supposed to take 1 day but it took 3, but hey, its done! Cost=$2100- as per quote.

The whole power loss thing is more of an issue with dual fuel setups where u need to tune the car somwhere in the middle. In a new car, you can get a dual map Unichip and they can set it up so there is vitually no power loss- 1Kw difference- ive seen the dyno.

My vette is gas only, so it can be tuned for maximum gas performance. Havent done any engine mods yet. We'll see how it goes anyway. I'm going away for a week now, so this be my last post till after next week.

Have fun at Motorex!

Interesting, never heard of anyone converting a Corvette to LPG.  Got any pics of the gizmos you had to install, if any?  I've never paid any attention to LPG vehicles so I don't know anything about them, so I'm curious as to why you did it as opposed to all the other options out there.

Brutus:
There are a couple of reasons we do it over here. Mainly for the overall costs involved and also because that most of our "Gas" stations pretty much all supply LPG for cars as well as petrol. Compare the price of petrol at the moment of around 80+ cents a litre to LPG which is just over 30 c/ltr. Even tho the mileage of gas is slightly higher that Petrol it's still a good saving. Plus the fact that any equipment involved in the conversion process is tax free.
I'm not sure which system WR has in his car, but this one is one of the more popular systems in the land at th moment. They've done a lot of performance work over the years and their equipment can be show quality if needed.
Here's a pic of their twin carb system with a small blower...nice and pretty... and it's yellow too.

hmm .. I think that unless you do a heck of a lotta kms, I'm not sure on the value proposition of a conversion to LPG.

If we assume a tank a week on average, using Shell Optimax, we'd be spending $50. Factoring in WR's $2100 for install that's 42 weeks worth of fuel but let's say a year with some off road time.

Having done the conversion and costing $2100 whlist still using roughly the same amount of fuel would be $2730 for the first year and $630 onwards.

So what we're saying is that without conversion it'd be a consistent $2100 per year whereas converted it's cheaper after the first year.

Yeah I can see that OK ....

Ok that makes sense, and doesn't look bad either, especially with a blower in there :22
