i know you high hp guys see gains from using a diffuser....but im curious if mild setups the average guy may run would see any from running one?

 

This is my TPR rear diffuser.

 

Holes in the bumper will help any vehicle no matter the power level.

Think of the rear bumper cover acting as a parachute, scooping up air going by under the vehicle. Causing drag and reduced fuel mileage.

These "diffusers" are just an esthetic cover for the holes cut out in the bumper to complete a cleaner look rather than just having random holes cut out.

 

When I got dyno'd I didn't have it on there yet, but between the fans and my exhaust that's pretty much an open dp with a turn down the bumper looked like it was gonna rip off. Hahaha

Is There any difference @ 1/4 mile?

 

Never cared for the round holes in the middle of the bumper.

I ended up with slits, and while not exactly perfectly scientific, I did go from 135mph to 139mph afterwards.

 

Lets see one on a del sol

a few more of ours on different chassis

 

Thank you 4 MPH that is fine !
How did you drill holes?

 

When doing this, did you have to support the space between the "slits"? I think I like this much more than the holes!

 

This is an RC Autoworks flipped with an FBM sticker on it.

 

Mine.
We've spent 5 hours to drill and fit it!!

 

Heres my ek which cost nothing other than a half an hour with a 2 1/2 inch hole saw.
