Track Days/Motorsport

Lorbek?

 

Who else?

 

So, a bit exxy then

 

IMO a lot of money when a similar amount will buy a Inter-Continential Brabham BT23B with a Climax engine .

Unless there a significant car , period 60s open wheelers seam to be the same price value they were 20 years ago .

Much rather have the inter with a 2.5 or 2.7 climax….

 

Still looking for a climax?

Sicko.

 

Maybe next year...

 

Those were the days...

 

???????????????/

 

Yep these days if you push too hard you risk bearing failure and piston damage…

 

Piston broke.

 

Ahh the good ole days…Then I decided to buy a Ferrari…

 

There you go Indy 500 2021 ...another 4 time winner of the greatest race .

I’m always amused when people say “Oh, you must be rich because you own a Ferrari”; My reply is always “I’d be a lot richer if I didn’t have a Ferrari to support!”

 

Racing next weekend (yay) so brake bleed and corner weights today

As a matter of interest, what torque is the wheel nut and tool used to do it please ?

I was interested to here that 812s use 120 for their torque setting as opposed to 80 for the 355

 

400 foot pounds. I have a big air gun calibrated for it but at circuits use a 3:1 torque multiplier with a conventional torque wrench. Never had one come loose.

 

Thanks, the nut is titanium ?

 

80nm?

That can’t be correct. That’s sounds as low as 11psi.

I could tighten to 80nm with fingers.

I was always at 130nm.

 

Now I have to go and check again !!!!!

Thanks for nothing Wes .... go park a car

 

I wouldn’t want your wheels to fall off.

 

it’s more like 80ft/lb = about 100nm

 

I think he meant inflate his tyres to 80 ft/lb.

 

Yes and no longer manufactured. For emergency I have spare steel ones that are much heavier, get the titanium ones crack tested regularly.

I used to worry about work hardening of the nuts, but then I read "Skunk Works", written by the guy who ran the Lockheed special projects division. They built the SR-71 out of Titanium and were unsure about its life. After 35 years of flying, they were stronger than new.

 

Close enough Greg, my torque wrench is ft/lbs and I have it set to 85ft/lbs

The guy with the 812 was told to do his to 120nm

I'm 1ft/lb below spec, oh no, my wheel will fall off

Of course my wheel nuts are titanium so now I'll have to check that
