Doesn't the V5 figure allow for a full tank of fuel and a 75kg driver @1979scotte ? < maybe I have that wrong dunno

[Gibla]

Did you ever do your weight reduction guide for dummies? @Petrus - if so would you link here please as a reminder .

Open a thread on ´Performance mods´ and we will take it from there.

Will do, maybe not today but soon

That one I'm not sure about but my turbo car was corner weighted at 1050kg.
I know some quoted weights include a 75 kg driver which is bloody stupid.
Give me the weight of the car with full tank and all fluids and I will take it from there.

Mr Google throws up a multitude of weights and scenarios, I should go and look in the engine bay + see what's on the metal plate + note what that weight is referring to.

Well played.
Can I just make out a centre zip?

Yes.

DI don't have the gumption to do it.
But well executed.

Thanks!

Tbh I don´t recommend it.
It is a AWEFUL lot of work.
Also had my heart in the throat more than once when drilling in the panels.

More a cool thing to have/do for the heck of it than a functional one. I think it makes more a near ideal parking cover* than a dríving thing in the light of the way Í like to use my car.
Looks very cool and intriguing though. Tótally classic too.

* even though pulling up the soft top, it makes the interior a fúrnace over here under the sun. Yes, the tarp is still black but there is no direct sunlight beaming heat in through the glass anymore. Especially the windscreen makes for a hothouse.
Leaving it down is exposing it áll to the sun, passers by and debris.
Pulling the tarp makes for a sometimes usefull extra.

That's gumption right there.

Oh my, thát has been a while 

Currently with a lightweight flywheel, new clutch, revised engine and repaired front end. While parked a myopic elderly man in a too large wheeled luxury SUV ran over that side observing that he had not observed it because it was too low...   Yes, he had his insurance sort the money side. Phew.

This is the flywheel btw; Competition Clutch Ultralight, saving just over 3 kgs.  The SMT copes seamlessly with it. From the picking up first movement driving  off you would not know its there. On the move the shifting is just that bit smoother and ´faster´.
With lightweight crank pulley, larger diameter yet lighter alternator pulley, airco delete and lightweight flywheel. the engine is responsive adding even more nimble feel to the car.

Today took the rear bumper skirt and crash bar off.
Deleted the black heathield, lightened the crash bar just a bit, faffed. with the license plate base & holder so I could use only the plate itself, screwed directly to the tabs on the crash bar, deleting two now superfluous parts.
Added just over 2 kilos of lightness.

Any issues with rear bumper "melting" due to black heat shield delete? Thinking of doing the same, have a stock exhaust so far, planning to upgrade in the near future.

Also what was the thinking behind cutting but not completely removing the rear crash bar? Do you think it adds to structural integrity or?

[Petrus]

No heat problem whatsoever. If anything is runs cooler because of improved ventilation.


The rear bumper máy add some rigidity but I am pretty sure it is not. The bolt fixture is simply not solid enough for that; it is designed to deform.
The reason I left it is convenience as mounting point for cable, license plate and the rear bumper skirt. I did take parts of the flat inside out and the outer ends.

Thank you for the swift reply! My reasoning is to remove the rear heat shield to minimise parachute effect, add lightness and improve heat dispersion. Ill probably remove the rear bumper grey plastic insert too due to same reasons. Need to see how will it look like and decide.

Cheers!

Also remove the drip tray and ... go for a lighter, smaller battery; that blocks air flow from the side vent a lot less.

Already got the lighter battery in for a year or so now, 5kg led vs 12kg stock. Not the lightest but more of a  best buy option

[Petrus]

Slowly, distracted by life and gfs, but surely... Now cutting off the bottoms of the spotlights 
Oh and they weigh just over 250 grams the two incl. modded fittings.

I haven't visited this thread for some time, but surprised to see that you have a big wing on the rear.

For someone who is as single-minded as you in the pursuit of efficiency, that wing isn't going to do anything on a road car but add weight and drag. Both of these things reduce efficiency.

Thanks for the information.

p.s. the confusion about ´road car´ is the weight assumed

So, believe it ... or not; tant pis 👌

Meanwhile sourced and bought a lightweight alternator. The idéa is that it has enough amps for my use and saves 2.5 kg, of which 1.5 rotating.

[Petrus]

ITV (Spanish MoT) passed. The handbrake was áwesome! and the emissions    0.02% while 0.3 is permitted.

Meanwhile sorted the lightness again 

Only motorbike no-muffler still to swap ad then the lightweight 40 amps alternator.

Also could not resist buying a replica TRD strut bar    Never liked the bent wonder currently fitted.

Yes, and then the bonnet. Should really REALLY kick myself under the butt and apply myself to making a GRP mould
