Just thought I'd share this for a few laughs. Took the old girl for a Power Run, just to get a base line before I make any changes. It's a NA Diesel, so be prepared for..
That's about 36kW in today's money
The right hand side of the graph is "Tractive Force" in ft/lbs, so if anyone has a decent formula for converting that to torque, I'd be interested. I've found a few examples, but my maths is a little rusty and the Imperial figures just aren't sinking into my brain this morning
Assuming a rough 35% drive train loss, it's down about 7kW from factory, which taking into account the 33" 4WD tyres, is in reality only a few down.

I don't have any achievements planned, don't really care about figures, but will be looking at bolting a turbo to give it some extra power on the open road.
I have some things planned and have been collecting fuel usage statistics for the last 7 months. I may post up a thread when I have some solid information.

Yeah, but the big test will be green mount hill on the way out of Perth. I'm pretty sure I chopped and changed between 3rd/4th last time I went out that way!
I'll mostly be interested in how it effects fuel economy though.

them tiny things you know pulled 65rwkw stock!!!
Andrew, have you actually put your smart onto the dyno? I'd like to see a graph if you have.
I have a Roadster and ForTwo and I can tell you neither of them gets close to that number. The Roadster with a Janspeed exhaust and Pipercross intake only gets 53kW at the wheels.

I'll look for it but I may have tossed it when I sold the car. The difference though is that my car was 1L so it has 33% more capacity than the roadster.
It's been on the dyno heaps 2 seperate types the 1st time I think it made 63rwkw even the 1L non turbos make 50rwkw but they are slow as. Mercedes gave me one for the day and I tested it out and that was consistantly 4 seconds slower to 100km/h LOL but used was less fuel.
Damn I miss the smart now I'd swap the soarer in an instant for it back lol

i found one here it is after all day on the dyno 2nd day testing where the ecu tuner couldn't get pat the computer and actually made less power than stock, it took them 2 months to overcome this and get the MAX power back to std! but at least gain 5rwkw down low i had the ecu reflashed back to std and took it to protek (dynamic test systems dyno) and it made 64.9 or 64.7 rwkw with the stock file... note also they are limited to 145km/h so the dyno runs to 500rpm less than redline in 4th... after the whole time the boost was increased 1-2psi peak and came on a tad earlier, also we found a way to unlock the speed limiter... the difference in driving was amazing... although note that the 451model hasnt had the development that the 450 model has had yet as they havent been around as long..... the 451 model uses a 1L made by mitsubishi 3cyl 2 cam 4 valve mivec engine, and runs only 7psi boost std.... ive heard of roadsters running over 20psi.... but the engine electrics are far more tricky in the new nodel and wont allow you to increase the boost, otherwise it cuts out and goes into limp mode.... really tricky ••••• not able to be bypassed easily or at all, and all the UK and europe tuners make up their reflashing claims as we got a file from europe and it did nothing... such a shame as the 1L with 14+ psi would go awesome.... as it was it was violent to drive, very fun

simon here is a comparison run between the smart with ecu mod (note the really slow gear shift time!) and the soarer when i first got it with catback exhaust and BFI
yes some say that app is crap etc... but if you calibrate it right its very accurate, i have a new gtech pro rr and the same times are confirmed, but i broke the cables and cant connect it to the computer
note how that if the smart had have had a dsg box or something that shifts faster it would be faster than the soarer, in real world driving it was awesome, great response and pulled hard at any speed any gear, really surprised a lot of ppl

Add a turbo, a decent intercooler and then a LPG kit.
I didn't realise it until recently, but a blend of LPG + Diesel on those old kind of diesels are actually pretty clever, the LPG acts as a catalyst and burns up the rest of the diesel. We all know those old diesels exhaust out some black smoke when you put your foot down, thats all unburnt diesel, and people say thats up to 30% which hasn't been burnt, the LPG acts as a catalyst and burns it all.
So that in simple terms is 30% more peak power, and 30% more fuel efficiency (and a tiny bit of LPG cost).

Well I'm going to test a Hydrogen Kit, that a few mates of mine have been fiddling with. I've heard good things, but I've seen no hard evidence. Hence why I've been collecting stats and had a dyno run. The gas kits, unless you have first hand experience to tell me otherwise, do help, but a couple of guys that I know that have them said they'd probably not do it again. But that may have been the type of kit, lots of computer problems (with the kit, both were Diesel, Hilux and an old Land Cruiser) with the gas kit, which they have spent more time getting it working than using. One of them, the shop went bust, so he's had to pay someone else to try and fix it. Probably says something about that workshop, but I'd need to hear some positive first hand stories about a particular kit and the workshop before parting with my cash/time.
Date: 07/11/2009 Odd: 236399 Fuel (L): 70.56 Cost/L: $1.189 Distance Since Last Fill: 612 Ks/L: 8.67 L/100: 11.53 Avg Ks/L over 3 tanks: 8.53 Avg L/100 over 3 tanks:11.73 Avg Ks/L overall: 8.72 Avg L/100 overall: 11.46 Fill Cost: $83.90 Cost/K: $0.137 Cosst/100Ks: $13.71
One of the tanks in the average over 3 included a run out to wedge island and up the beach etc, which was 12.06 L/100

Well we're doing the gas to a hilux surf, if you're interested I'll let you know results. It will be his second gas powered vehicle, the first one was pure LPG no mixing with other fuels. He's had a few issues with it but generally it was electrical based. Some poor earths were fixed and all good as gold for 130 000kms.

Straight Gas/Dual Fuel has been done to death, so I know the deal with most of that. The mixed Fuel/Gas is interesting, so would be happy to hear your results.

Hehe well I'll do my best to document what I can, but most of it will be done by a shop. There are a few benefits of a mix, one of them being that you don't use so much LPG that you risk it exploding in your intake piping!
What started me being actually interested in it was a few articles like this one.

Probably a better 1/4 mile time too!
