S&S flywheel assemblies have established more 1/4 mile drag strip records and Bonneville Lands Speed records, than all the other companies combined times a factor of 100.

Never had an issue with Tech Support... Good guys....

 

Their 5 piece TC wheels were a bust. Have had 2 spread, One was rebuilt by dark horse and is spreading again.. The other went in the trash and was replaced with a 3 piece SnS.. I guess I supported their RnD..

 

As did JIMS, as did S/E, as did others, in the early stages of the press-together fitment.
We witnessed it/lived it as well.

I've heard they S&S valences their wheels to 50-52 %. Any truth to that?

 

For twincam, that is correct. I would expect a solid mount evo motor to be balanced to more but I seem to remember my SnS 113 motor was at 50%..

 

Here's the dyno chart from S&S if anyone cares. Great numbers and it's awesome to start seeing the M8 stretch its legs.

That power dip at ~3200 rpms though ...

 

Doesnt an identical TC 124" make 140/140 without the dip?

I guess you have to work with what they give you.

 

Not on an S&S dyno- It depends who's dyno, what parts, and what and who is trying to sell you something...
Apples to Apples, you can compare with this-
As far as the dip, again, S&S is trying to bundle their own pipe in this package to sell it. I'm pretty sure another pipe would and could smooth out the dip quite a bit...

 

Oh with a carb too? (Lol) yeah some power on the table there
