nothing glued into position yet. overall i think it's gone well. I'm more relieved than pleased at the moment.

Just perfect mate well done, there are some curves to encounter arn't they
Thanks Steve. Just the boring bit left; sanding and glueing. Which particular Sikaflex did you use? I'm looking at the 512 on ebay.

People that attempt this deserve some kind of medal for bravery
i was shaking making the first cut. it was much easier than i thought it would be. normally i cut galvanised steel at work so the bonnet was much easier. the NACA duct was quite tricky. 3 practises on other pieces before i had the confidence to cut the bonnet.

512 should be good, i had a general purpose sikaflex about 2years old ! but when I cut the top off it was solid!! so I used some thing else that was handy called master seal.

Paul ,it looks like you are placing the vents onto the bonnet rather than flush fitting?? tell me more
the final pictue just shows them in place. I've made a "frame" underneath. I'm gonna glue the frame to the bonnet then glue the vents to the frame. masking tape is holding it altogether at the moment (purely for show). that's why i went for 1.5mm ally. with your 3mm ally i'm guessing you had to put some packing between the bonnet and the supports.
they will be flush fitted. i was tempted to place the NACA/ NANA duct on top and use filler cos it was easier when cutting. don't think i made this clear in previous post
Alpina Style Bonnet
Where did you get the pats for this mod I have someone her in Vancouver who has the louvers made for $300,But what about the NACA Duct.? I ask because I am in process of moving back to the UK and this was one of the mods I wanted to do now that I am retired. I haqve a 1991 LHD 850 with 44000kms I an bringing over.The attached was a mock up of one idea I had but I want the Alpina model really. The diagram is of the louvers from Vancouver
Bonnet vents
Sorry these were the vents I had made for $50. These are the Alpina style I can get for $300. Are you glueing and not welding the bonnet?
i'll be glueing for 2 reasons.
1. i've never used a welder
2. if you search this forum you'll find that welding the bonnet will damage it
your vent measurements appear to be correct, though i doubt alpina designed them in inches
sorry nick. didn't see your first post. the NACA duct was £12 +P&P from ebay. I don't think it's the same shape and size as the alpina one. there are plenty of options available.
