Need to find the big filter that has the pleating of the small filter. size isnt everything.
you are right the small pleating Does flow better. Oiled gauze is the best flowing media, paper being the worst and synthetic media in between. The more surface area you have the better it flows as your not pulling as much thru the media and have lower velocity.
Oiled gauze also allows the most dirt thru. Paper and synthetic are better at filtering which means they both get clogged faster.
after all our testing on the dyno and research I believe Synthetic is the best over all choice if you have enough surface area.
what you can’t see in this photo is the larger filters pleats are 3x the depth of the smaller filters pleats. If you were to spread these filters out flat the larger one has 12x the surface of the smaller one.
that being said this is all a guess as we have not ran the new Slarger filter yet. Testing and ultimately the first race will tell us if we are right.
We are adding a MAP sensor in the filter so we can see if we create a vacuum at any time in the race or testing.
I try new things but we test and verify everything we do. Data matters.
the intake tube and velocity stack we are using will for sure be the best it can be. I think we will pick up at least 10hp from the tube and velocity stack alone.
hopefully we do not get less flow and less power with this larger new filter. It can’t flow better than our oiled gauze but it can flow worse. If it flows as good as it should then it will give us more flow at the end of the race as it can take more dust load.
