haha yeh..i think most people went thru a ricer stage sometime in their life. I sure as hell did...to bad my ricer days are over though...ha

everybody's hatin. hopefully he's also swapping lug nuts, wheels studs, brake nuts and bolts, axle nuts, that'll make a big impact. i'm also curious how much total weight this will reduce.

gotta love s2k owners haha...in for total weight savings

Aren't there some safety issues just swapping steel for TI? On a race car where things always get taken apart, inspected and replaced I can see it but for a street car it might be a liability especially on suspension bolts. I have no problem at all with someone spending cash on details to drop weight.

We just took 388lbs off a '70 Nova at work. No titanium was used.

There are. Titanium galls and causes galvanic corrosion around other metals because it is typically lower on the galvanic scale. Depending on the alloy it may be weaker than steel. If these bolts were cut and not properly formed then the stress concentration and crack propogation issues would be a big red flagged cause for concern. It also becomes brittle with heat when in an atmosphere containing oxygen. Titanium is about half as stiff as steel, (~110 vs ~200 GPa). That's off the top of my head, there's other concerns as well. There are alot of places to save weight before possibly compromising an engineering design, hopefully the guy did his homework if not: more money than brains I guess.

Thank you. Residual stress is a killer in Ti products under any additional stress. Eventually something critical will fail with his car.

McMaster Carr has some titanium nuts and bolts.

Heres how I dropped a 1000 pounds off a normal car

We've all throw plenty of money away on bullshit in our lives. This guy has a goal and he's working towards it. If Ti bolts were so ridiculous then most high end race cars wouldn't use them. Believe it or not, Ti bolts can safe a pretty good amount of weight over steel bolts when done in qty.

At least he's not buying crack or something...</TD></TR></TABLE>


so crack is bad tony?

How do you keep those things from galling? Anti-seize on all of them?

duckmanEG

Tastynuts.com has a good selection of TI bolts.

http://www.tastynuts.com/site/...e.htm

Did he buy throw a source or did he have these custom made?

Either way i am with Tony. We all spend money on our hobbies. To say one expense is not good because it might not be what you would do, doesnt mean it is wrong. But people raise good questions about how its going to react.

I was going to say something to the same extent, but I figured I'd get "OMG Ti LUG NUTZ FTW!!!1" or something along those lines.

new2novas

pretty cool actually, are the threads cut or rolled, gonna add 5 pounds of antizeize though haha....sounds like a fantastic customer....i will pay you to replace bolts, sounds good to me....

heres the rice stage i went through, understand this was a bit over 10 years ago now

fusion210

I think it's cool. I even have a few on my car.

Has your customer also considered nylon and aluminum fasteners?

worn titanium retainer=drop valve
worn suspension bolt=dropped car

If I knew the size of the bolts, I could source them out.

Doesnt the KTeller site list their Ti hardware at Grade 9?
I might be a little noobish in the Ti arena, but isnt a grade9 bolt stronger then a grade 8?

I don't think you can match the shear strength or having anything close to the elasticity (stretch) required by steel for use in critical components. It would be just plain dumb to run Ti bolts where driver safety comes into play.

I would NOT use Ti bolts for suspension/brakes, anything inside the engine/gearbox.

I would use Ti bolts for all the misc. crap inside the engine bay, like valvecover, all the little 10mm bolts that fasten wire harness sections...you know, the unimportant ones.

Omniman made ti bolts for BVTEC cam caps for a member on here. Worked fine.

ti fasteners are very common in mountain bikes. Have been for a long time. Would I use one for a LCA or shock? No, but there are acceptable places to use them on suspension and brakes.

I'll call BS, I make bolts for a living, your customer doesn't have the $$ to have bolts made. Not saying he couldn't source them, but I'll guarantee he didn't have them made. The pictures you showed would have over $250 000 in tooling associated with making them. He can buy them though, and realistically if you guys knew how much steel bolts cost per piece, I'd bet that those Ti bolts don't cost all that much more.
