here's a link to a HUGE jpg (1:1 scale) of the shroud/channel outline ...
i'm going to clean this up, run it through adobe streamline and make it a vector graphic EPS. then, i'll have the shroud lasercut out of aluminum sheet metal ...

more "babysteps" ...
got off to a slow start, didn't get to marks until noon-ish. (IMG:http://www.914world.com/bbs2/html/emoticons/dry.gif) so i decided to just cut out the new front support brackets. mine are shot (dumb PO (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif) ) and i got two replacements from John at EASY. of course he didn't drill out the spotwelds, he just cut the frontend around the pieces i needed, so i had to drill out all the spotwelds to separate the bracket from the junk ... here's a before picture (yellow! (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) ): Attached thumbnail(s)

mark convinced me those would be much nicer all cleaned up, so we started up the bead-blaster box ...
turned out really nice, except, it takes FOREVER ... (IMG:http://www.914world.com/bbs2/html/emoticons/rolleyes.gif) Attached thumbnail(s)

and then some primer, so they don't turn into a heap of rust by next weekend.
by the time the blasting was done, it was 6pm. time to call it a day. i didn't get any of the other parts that i had planned on working with today, so this is going to be a short weekend. hopefully more progress next week. including welding those babies in place ...

curious in your method...
cut 3x, fold 2x..... seems like the cut once and louver punch is easier (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) cant wait to see it... |

quick and dirty photoshop mockup ... 3 cuts, one long horizontal, two short ones on the side (about 2" total) ... then, bend front part upwards and bend rear part downwards ... that way, each cut (louver) has a lip that will create suckage (neg. pressure) ... this should help with the airflow ...

I like the louver idea, but your air funnel looks big enough for a radiator on a V8 car. If you tilt the oil cooler forward a bit then you could have the funnel match the hood line much more closely and recoup more front trunk space. Just a thought, maybe it's just how it looks in the picture, I wasn't there, blah blah blah (IMG:http://www.914world.com/bbs2/html/emoticons/cool.gif)
Mark, congrats on getting Andy to clean his parts (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif) |

ok, here's a small JPG of the oil-cooler shroud lineart ...
the original is a Adobe Illustrator EPS in 1:1 size that Mark will use on his plotter to cut a template. this should be fun ... (IMG:http://www.914world.com/bbs2/html/emoticons/type.gif) Andy Attached image(s)

Andy,
I may be able to cut your shroud for you if you can supply material. Send me the file when you are ready. |

CFM flow for the hood louvres looks to be much higher than the CFM flow for the cooler. Simply based on surface area the cooler is 21" x 6" (126 sq. in.). Andy's using 3" openings so two 21" openings will equal the surface area of the cooler, and Andy's using three openings. So it's already bigger. PLUS, (yes there's a bonus) the oil cooler obviously isn't going to flow nearly as well as an opening of equal area. BUT the air will expand as it's heated. All in all, I think these three louvres will give more than adequate air flow. |
