| Subject: | Air Ramp Cracking |
After a mere 60 hours TT I have noticed cracks around rivets on the F867 ai
r ramp on my RV8A.- The cracks are at the outboard rivets that attach the
air ramp to the center F867D stiffener.- I suspect there is a lot of vib
ration from the engine exhaust pipes that end just about in that area.- I
have the standard Vetterman exhaust bought through Vans and after about 20
hours or so I added a set of 20 degree turndown exhaust extensions from Ve
tterman.--The extensions-seemed to help overall noise and vibration i
n the cockpit, but obviously there is still a significant amount of vibrati
on causing the ramp to crack.- It looks like I'll have to replace the ram
p, but that is not addressing the root cause of the problem.-
-
Has anyone else seen and solved this problem?- Additional stiffeners on t
he air ramp?- Longer exhaust extensions?- Any help would be appreciated
.
-
Thanks in advance.

I just sheered a piece of stainless and popped it in place. Oh I also bonded it
with Pro-seal to hopefulle stop any vibration. It runs the full length and width
of the exhaust ramp Its a simple fix that actually looks good with no paint.

I had the piccolo type extensions on mine. Good sound and no cracks in
365 hours. Otherwise ramps were stock.

Strongly agree on using pro-seal around the edges of the ramp. It reduces
vibration and seals oil and such from inside of the double floor.

ACS says "3db" noise reduction, but I wonder what HP reduction? Those look pretty
restrictive...?

I gained 10 knots and fuel burn decreased 1.5 ghp. Just kidding. I put
them on early, and never got around to testing. I had typical RV-8 speed
numbers and had no problem keeping up with the others, so if there was a HP
loss it was negligible, IMO.
