yes, the 85lb is just the block as it is running now. The FF, dry, will be 170lb. Keep in mind it is 12A based. The 13B based will be a bit heavier.

 

 

Hi Richard,

 

Do you have a weight for all of your redrive components?  I'm trying to get a comparison to Tracy's 45 lbs weight, which includes everything but the flex plate itself (I assume).  When you add the Hirth drive, mounting plate and hardware, input shaft, drive coupling mechanism, what does it come to?  

 

I think I guessed that would all be about 30 lbs.  Tracy's drive could fairly easily be reduced to about 40 lbs, and possibly a bit lower if weight becomes critical.  Fortunately, it's not critical for me at the moment.  It's also yet to be seen how the RD-1C will cope with the pulse frequency of the single rotor near idle.  There may well be some dampener durometer modification to be done.  I won't know until I fire it up, which should be around the end of the Summer.  

 

Thanks,

Rusty (climb test will have to wait until tomorrow)

 

Hi Rusty,

 

you could not use the componet weights of my set up because the externals of my side housing have nothing in common eternally with the MAZDA housing. My mounting plate for the redrive is much smaller than what you need. My flywheel is 10" dia, and the mounting of the adapter plate is very close around the flywheel. Essentially, I have nothing further out than the tension Bolts, or for that matter, the rotor housing outer contour.

 

Sorry to be not of more help on this one.

Richard,

Thems good ideas, I had wanted to use a smaller flywheel myself and found the Subaru to be the same tooth profile - but as luck would have it, I had to make it compatible with the auto flex-plate, as that's what most are using.
