[Fot] max. TIR for TR4 aluminum flywheel?

["J.C. Hassall" <jhassall@blacksburg.net>]

Amici,

What is the maximum flywheel total indicator runout you'd feel 
comfortable with?  I was finally able to remount the Fidanza f/w on my 
TR4 engine this afternoon, only to find that it has 0.005 TIR.  I have 
no record on my build log of the previous runout, so I need advice.  
Given that it's for "fast road" / autox, red line 6K (nitrided crank, 
lightened and balanced rotating bits, PP and f/w balanced as an 
assembly), do you think 0.005 is too much?  Since all mating surfaces 
were clean and smooth, of course I was shooting for 0.000, so needless 
to say I was disappointed.

TIA

jim
