Just curious why you want the spacer? I build a wood spacer once to try on a single plane to test for more power, but i couldn't bring myself to install it...lol. I did try several aluminum one's but on the street didn't feel any ''seat of the pants'' gains so i did away with it.
Good question. I am not running the spacer for HP as much as I am running fuel injection and the spacer apparently reduces noise from the injectors that is common with the sniper systems.
