Roofrack ideas

[colin s]

Hi all,
Just had a Rackmaster roofrack fitted to my 130 and have now got an awful drumming noise from the turbulance as wind gets trapped between the roof and the rack.:eek:
There's a gap of about 60mm between the rack and the roof. Just wondering if its a bit too much or will the air get between even if i lower it because of the slope at the front of the roof.
Any ideas are greatly received.
I'll post some pics of my Fender if i can sort out how to do it:)

I am not familiar with the Racklander , but I have a Jaram roof rack on mine with a perspex air dam on the front ... i had the drumming too nyting over 80km per hour or cross winds

I took the legs off it and cut them down so the rack has next to no gap the difference was amazing , re worked my awning so it fits really nice and tight between the rack and the side of the body work

mind u I have no where to slide my table now .. it used to bolt up between the roof and the rack :p

Easy fix buy a 4bd1.
My roof rack has never made a noise.
I have heard they make pintle hooks quiet as well.

I have fitted an alunminium or stainless folded section to the front of my racks for years.

Don't think I have one now though as the Isuzu fixes all other noises!!

Will tray to expalin; 20mm section flat to fix to front of rack.
Fold 50mm long section to run down at 45 degrees towards front of vehicle.
Return fold at 90 degrees to run back at 45 degrees to rear of vehicle.
Return fold at 45 degrees to make flat section at 20mm at base of profile.

Not sure why it works , I justy saw it years ago on a tradies rack and got them folded up.

It may be something to do with the air rushing around that 90 degree proifle and not closing the air patern until it's past the rack.

Colin,

I have the 2 meter windcheater from Dolium, (which I believe is also marketed as the Rackmaster from O/L) on my 110, its mounted over the rear flat section up about 60-70 mm. I haven't noticed any noise from it at all, however when I got it they gave me a small square (40cm x 40cm ish) of aluminium plate with a little lip that they called a wind deflector, and I installed it as they suggested, underneath the front of the rack. Do you have this?

I have a Rackmaster on my FL2, at first I drove without it and the vibration made it impossible to go over 80km/h. Once fitted normal highway speeds were possible again, if you don't have it you need it.

Yeah Guy's, i've got this "wind deflector" fitted. It was a rack that i had on my Troopy and there was no vibration with it when it was fitted to that, although it was fitted at the flat part of the roof.
Maybe because i've got the front of the rack fitted plumb with the front of the roof its causing the problem. As i say, its heaps better now i've put the roof tent on but i do need to be able to take the tent off. Going to see how it goes this week with a trip to the city and then decide what to do from then.
Thanks for your input.
