keybaud Posted September 9, 2012 Share Posted September 9, 2012 Is there a recgonised way of marking up a hole that needs to be cut in the bonnet? I need to change the shape of the existing hole for the throttle bodies that will now be fitted as if they were DTH and not horizontal like the carburettors.

The Pikey Posted September 9, 2012 Share Posted September 9, 2012 If you happen to have a Duratec on raceline mounts then I have a template. Link to comment Share on other sites More sharing options...
keybaud Posted September 9, 2012 Author Share Posted September 9, 2012 Quoting Jason Fletcher: If you happen to have a Duratec on raceline mounts then I have a template. It's a Vx, C20XE. Link to comment Share on other sites More sharing options...
Harry Flatters Posted September 9, 2012 Share Posted September 9, 2012 Mine is a VX on tapered Jenvey TB's. If this looks like the sort of hole you need, I'll do you a template. Link to comment Share on other sites More sharing options...

I reply to every thread Posted September 10, 2012 Share Posted September 10, 2012 EFA uses some method involving, tape, string, smoke and mirrors which is extraordinarily accurate Link to comment Share on other sites More sharing options...
charlie_pank Posted September 10, 2012 Share Posted September 10, 2012 I used a lino stencil. Was pretty nerve wracking doing the cutting. Just remember 2 things: - You can always make the hole bigger if necessary, smaller is more difficult - Measure 3 times from at least 2 different reference points, cut once Link to comment Share on other sites More sharing options...
Chris Cardwell Posted September 10, 2012 Share Posted September 10, 2012 Would it be posible to experiment with a small sheet of aluminum positioned where the bonnet touches the nose cone. Otherwise add an industrial robot to the EFA list of techniques . . . Link to comment Share on other sites More sharing options...
k.russell Posted September 10, 2012 Share Posted September 10, 2012 this is how i did mine, take off the trumpets leaving the backplate bolted on, using a square on the back plate you can mark through where your existing hole relates to the backplate and can also mark how far up the bonnet you need to cut to get the filter airbox through.

k.russell Posted September 10, 2012 Share Posted September 10, 2012 this type on snips/ nibblers is the best for cutting ali, i bought mine from RS but they are available widely. suggest as have others cut below line then dress with a rotary flap wheel in dremmel or drill.

EFA Posted September 12, 2012 Share Posted September 12, 2012 I did it when I first did the ITG on K2RUM by fitting the filter then running string between the nose and scuttle, marking the points where it intersected with said panels. Measuring the front and rear position was easy. I then plotted all of that onto masking tape stuck to the bonnet, and guestimated the corner radii. Worked on that car and filter plus all of the DITP airboxes I fitted. Link to comment Share on other sites More sharing options...
