Project "Marginal gains..."
Turbo Mini Forums

could you not fit a tubde from inner sill/main hoop to inner sill/main hoop on the other side under the seat base to stiffen it up?

Yeah absolutely, a tube across is a perfect way to stiffen things up except for the weight put back in will end up very near if not the same as the ally box section I took out. It's pretty well 1200mm inner sill to inner sill and even going down to 1.2mm wall 38mm tube (too wide a span for a smaller diameter to add any useful amount of stiffness I think) it comes in at 1.3kg before I think of adding any bucket bushes or gussets back to the mount points.

As I say I want to improve exhaust clearance where the tunnel meets the heelboard which the current ally box section obscures. I decided I'd only pursue this route if I could solve the clearance issue and save a reasonable amount of weight at the same time, I couldn't justify the work involved if the only gain was clearance and very little or no weight saving.

Looking good mate! I love the thought that is going into this car.

I have started posting on Instagram also my name on there is turbomk1golf

Nothing is impossible it just costs more and takes longer.

Looking very neat. Keep the updates coming!

Cheers Simon and Jonny

Hopefully I'll be able to make some steady progress over the coming months

Cheers

I decided I'm happy with the overall idea so started to weld up in stages while I keep it bolted to a straight edge and using the ally box section as a jig and checking it still bolts up so I know it hasn't moved too much after welding.



I think I might calculate the weight of adding the same sort of section in the centre so this increase in section depth goes all the way across the heelboard like a continuous box section again.

Cheers

Looks nice and neat

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!

More ‘marginal gains’ in the post



106 grams, down to 14 grams

This is FORD country, on a quiet day you can hear Vauxhalls rusting.

Thanks again Steve, if only I could make the same percentage gains on everything else!

Cheers

What are the carbon discs for?

Air vent blanking plate I believe

This is FORD country, on a quiet day you can hear Vauxhalls rusting.

Surely not blanking them is even lighter!

In the 13's at last!.. Just

Any updates?

Any progress on this?

What happened to this? Any updates?

One of my preferred builds to read on this forum. Be nice to see what progress has been made.
