Has anyone tried these things?? They say it spins the air charge to increase horsepower by 10-15. Sounds like a gimmick to me.

 

Kinda like the "ripoff" Tornando... just more professional looking. Even if it works, won't matter on our L. The s/c pulls air in and spins it. Doesn't matter if you spin the air, the s/c will only allow the air to flow the way the s/c wants it to.

I wouldn't buy anything from powerdyne....

 

Powerdyne LOL. Enough said.

Their 9 PSI kits make 5 PSI.

LMAO

 

does the air spin in the opposite direction, on the Australian model??
