I remain on the Ford Focus , first because I had a car full of nothing and then because if I use a completely new engine and all new to me and I can not even have a lot of help here in the forum.Maybe in the future.
Anyway guys , you have to decide to know how heavy the Mabbs. One says 460-470kg.Another says 550kg. There someone who knows exactly?
My 17 inch rims weigh 7.2 kg.Das is a good value , I find.

I want to make changes to the engine, for example compressor.After this.
But as it was explained and not a question of money , but my Hobby. And do not even want to have quarrels with members of the forum , but only an exchange of ideas and solutions.Is this a risk you can take.I will do everything possible.

The correct answer 545kg as per the plate shown on a picture on this page. mevowners.proboards.com/thread/563/mabbs-build?page=27Matsmev believes his is the lightest built to date at just under 500kg but had a 1.6 engine I think, certainly not 2.0 anyway, which would save a lot of weight. Jimk was the heaviest at over 600kg but he used a lot of stainless mesh panels. |

I'm using the Duratec & have already purchased an aluminium flywheel & heavy duty clutch from Spec Clutches in the US. This will be to replace the original dual mass flywheel & clutch.
Its about half the weight.
I'm also converting all the suspension over to use imperial bolts & using the same for everything I can (everything except the drive train) as I have purchased a whole heap of chrome moly tubular bolts, by "Racebolt". They're 1/2 to 2/3 the weight of the equivilent standard bolt. They're also twice the price. If you were to go to titanium, you'd be talking AT LEAST 5 times that again.
For basic fixings like the dash, sheet metal, and holding non stressed components, I'm hoping to use aluminium fasteners, like they use on bikes.
1 of my businesses though, is retailing racing car parts. So its more because I can source this stuff easily, rather than any other reason

Aluminium flywheel is interesting, what about the starter ring and the wear from the clutch plate? Titanium exhausts are very light and durable, however expensive, the material is difficult to form (tube and sheet). Interesting thread... They use a still ring gear & a steel insert where the clutch runs. Both bolted on |

In my opinion, trying to save 100kgs from a car that only weighs 550kgs to start with will take a huge amount of effort and money.
As with any process of lightening, you need to look at the items of largest mass, to make the biggest saving first.
Engine/Transmission
Driver!!!
Wheels & Tyres & Brakes
Thats where your biggest savings will come, if you're really serious
Good luck, I'll follow this with interest

Kiwicanfly: Thanks for the information about the weight. In fact, my reference was the car of Matsmev under 500kg.E then would be about 50-60kg I should drop weight. Driver: 68kg..But it remains so.....  When the drive shaft can pick out some.Do I need to take a closer look die. I am very curious to the titanium bolts. I hope arriving today |

At £7 each that's nearly £120 for 18 bolts.
I spent £110 for every nut, bolt and washer used on my build and I still have loads
of them left.
I admire your commitment to your build and also your very deep pockets...
