Im hoping to use titanium for my exhaust, a chap who i work with makes titanium silencers so going to tap him up for one. Titanium tubing is very expensive but may look into buying a system from another car and making it fit.

Also if you want some titanium bar to take to the engineering firm to cut the cost, i may be able to get you some ;)

Thanks Ste, that's appreciated.

Out of curiosity, do you know the like for like weights of titanium vs. mild steel? i.e. if the exact same item was made in each material, what would the weight difference be?

I can find out for you colin, obviously there are differant grades of both materials. I will get you some comparisons this week from the titanium we use.

That would be great thanks. Not after perfect accuracy, just a broad brush figure e.g. titanium is roughly 50% of the weight of steel.

Yes.

I haven't explored that one yet.

cracking car colin, after seeing it today i cant help but wonder if you could fit a 16v head from a 1400 corsa to give you that little bit more.

cracking car all the same mate

nice to meet you !

Good to meet you as well.

The 16v head is a possibility, the big question mark is whether the very narrow bore size will give enough surface area to fit 4 valves into! This is something that we'll measure next time the head is off.

A few other things on the shopping list now, although they may be a long way off before I can fund them;

Titanium driveshafts
Titanium flywheel
Centrelock wheels (as far as I know never seen before on a Nova?)

Hi colin, still waiting for an answer back with regards to steel vs titanium.

Who will be making the centrelocks? Would it be x sport racing?

Has the enginereing firm whos making the parts mentioned the life span of them?

No, it's not X-Sport.

I will share more details with you after I've had a chat with them, which should be today if all goes to plan.

I'm only going to go with centrelocks if it offers a weight saving. Although they would look incredible it's going to cost a lot of money, so it would have to offer a tangible benefit!

The tubed titanium driveshafts look like they will give a significant weight saving, and one assumes are stronger as well.
