The weight saving thread

[richie]

   yes that is a carbon shifter handle[about half the weight] and alternator pulley [1/3rd the weight] 

[richie]

   Doors fitted to car with new hinges and handles, all works good

[richie]

More stupidity    Fuel tank clamps in carbon, steel 24g, carbon just over 7g each, 4 is 29g!!!

you just need to sell them with titanium or aluminium bolts, though aluminium might be a bit weak in a crash situation

I will try not to crash then   Did fit a pulley today to one of my cars and seems to work ok, will give it some milage and high rpm tests now and see if it falls apart

Still the best thread on the entire internet

Those valve covers are definitely cool, id bet you could sell those especially if you made a set thatd clear ratio / high lift rockers.
Only argument i might see against them would be heat transfer. How much heat is normally dissipated thought an aluminum cover though?

How much lift clearance do you need? these clear 650thou lift already, probably more but not built anything for a while with vw style covers that lifts more than that and I don't run aluminium covers anyway

Can't figure out how to lighten a Vw front
You can put lead in the front if you have to drive fast
Because having the front wheels 1m up in the air does not give good times

While i mostly agree, if we do more work on the front end aero to try create more downforce then we can safely run a lighter car

Bugwelder in Germany has 2 new Alternativ(Drehstrom!), old Style 90mm and 105mm
45Ah 12v

90mm =   2,5kg
105mm = 3,1kg

This thread has always been fun to read to see the innovations that come out.

Those carbon parts are awesome Richie.

[richie]

Been a while since i made anything new that i can show , had people ask for these in past but it was low down on my list, got to them now, weights are showing factory headlight ring and factory glass lense against carbon headlight ring and my plastic headlight lense, every little helps

I was talking to Eric Ballard last week and asked him about his lightweight car he ran in the late 80s.
He said he removed all the double skinning from the inside, such that you couldn't tell from outside that the car had been gutted.

In his gearbox, he lightened many of the parts.  He core drilled the mainshaft (but not past 2nd gear)  He said he removed over 1.1 kg from the ring gear alone.  The gears were narrowed and drilled.  I think he said the axles were drilled too.

The end result was that he had a drag car that weighed under 450kg without driver.  And that included a roll cage and wheelie bars.  And all steel body panels.

Hi Bruce

I now own this car, and it may have been that light but its definitely not all steel

cheers Richie

I would need 8 pcs of 12x45mm hexhead bolts with 1,5mm pitch made of titanium. Any suggestions?

There are a lot of China sellers on ebay that sell low volume quantities of Ti bolts. Most of the M12 bolts are 1.75mm thread pitch.
