Making wirlwind pipes fit
Discussion
I got them with the GB a while back & when fitting them found I needed to trim the scuttle panel as was mentioned at the time so they would fit. However I have found they are still rubbing, but I'm reluctant to take too much more off the scuttle for fear of weakening it right next to the bonnet supports in it. Has anyone taken more than this amount off?
Incidentally the little tabs on the back corners of the scuttle where they should slot under the windscreen have always been broken, I guess if I actually got around to fixing them it may help hold the centre of the scuttle panel up a bit & reduce the rubbing. Any one tried that?

Trim the actual pipes down a bit. Take it of, move the jubalie cip down a little and do up, then run a stanley knife round and put back on.Incidentally the little tabs on the back corners of the scuttle where they should slot under the windscreen have always been broken, I guess if I actually got around to fixing them it may help hold the centre of the scuttle panel up a bit & reduce the rubbing.

That does sound like the easiest option, but on the old GB thread some one said they were buying some more because they had trimmed their first set down & they didn't fit properly any more. I guess just being very careful would be the key, have you trimmed yours successfully? That moving of the jubilee clip sounds good, would stop the blade slipping if I moved it up a bit before trimming... job done

You could also try remounting the airboxes by drilling new holes in the brackets.
My air boxes are as low as they'll go, they catch on the rocker covers if I try to take them any lower, I could space them out & move them down a bit but its the other end of the pipe where it rubs so it wouldn't make a huge difference. 
Buy a litre bottle of Orange juice in a round plastic bottle (choose one that is as close as possible to the size of the intake hose, and one that 'looks' like glass as they are a thicker plastic) Then cut a piece out of the bottle, the bigger piece you use, the more the load is spread over the hose. Bond it in place with some clear silicone where the scuttle touches the intake hose. You can make it as messy or as pretty as you want.
PS Drink the orange juice before cutting the bottle.

Trimming them was fine with the new blade & using the clip as a guide, cheers. Trouble was they still rub & if I take any more off I'll cut all the truly round bit inside away.
I do like OJ though, so will enjoy drinking it
Did you bond the bottle to the pipe or the panel? I guess the pipe, as the bottle would slide much more easily against the fibreglass as the engine moves.

Yeah, bond it to the pipe, it's a nice shiny, hard plastic so the scuttle just slides against it.I do like OJ though, so will enjoy drinking it

Thanks JensanA I’ll go orange hunting later & give that a blast. I think protection is the best bet because it’s hard to tell just how much the engine could move & so then just how much clearance would be needed to be safe.
Why has the PC only just seen fit to point out to me I've been spelling whirlwind wrong this far through the thread

i trimmed mine from both ends. Austec told me i had to do this anyway to make them fit
So Austec selling whirlwind pipes eh? How times have changed in the Cerb world.... Why has the PC only just seen fit to point out to me I've been spelling whirlwind wrong this far through the thread
Luckyone,
You must have a fairly old ish set of Whirlwind pipes as I seem to remember that it was ony one batch that needed trimming?
If you can't do what Steve suggested in moving the airboxes (drill new holes so they fit lower or further to the front of the bay), and you feel as though you've trimmed enough off, then the orange bottle sleeve is an interesting but good option, it shouldn't get too hot under there to melt the plastic.......I hope.

What's the Scuttle ? 
The yellow body work you can see in the picture, as far as I'm aware it's a generic term to describe that part of any car. I think I've heard it referred to as the F1 panel on here but I'm not certain of that. Steve_T said:
I think he meant that the ACT pipes are trimmed to fit also.
That would make a lot more sense!Juddder said:
Off topic (sorry) but Jules have I got your old 4.2 Cerbera?
Specs/Colour sounds pretty much the same :-)
Hi,Specs/Colour sounds pretty much the same :-)
Yes I owned your Cerb back in 2003, it was my first Cerb and I think has had 3 or 4 owners since.
Here's the link on James Agger's website when I bought the car, the previous owner Garth is also still on PH.

ps It was one of the very first Cerbs to have the blended Speed 12 type headlight upgrade (quite controversial back then!!)

Sorry Luckyone for the thread hi-jack, so back on topic now....
Here's a pic of the original prototype Whirlwind Induction

Sorry missed this yesterday & then your second post. I got the Whirlwind pipes in July 2009, I don't know if that old or not? Looking at your pics they are a bit of a different shape, the bit attaching to the throttle bodies looks longer, hence them catching. (if my server comes back I'll post the pics)I seem to remember these were the second generation meant to fit better? The air box outlet is touching the mounting plate at the end nearest the cabin, that's what's stopping them going any lower there.
