Wow, I can't believe the flat 12 in Paul's pic is cantilever mounted to a standard Porsche engine stand! (IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif)

Thanks for starting this thread. I am in the same process right now.

Question to all: is there any advantage to which way the carbs face? Specifically, having cross-bar closest to the cockpit vs closest to the trunk? I've seen picture of both installs.

hope this isn't a hijack

look are where the drop links are positioned in that picture (under the rear lid? (IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif) ). you have to stand on your head to dial the carbs in. what keeps the bar centered? a couple of springs?

Having the arms to the rear is no big deal... you set it up properly once and that's it. More time is spent adjusting fuel mixture and synchronizing both carbs... then adjust your drop links to fit with the throttle arms horizontal without any side to side preloading of your final carb set up.

It also makes for neatly routing the stock length throttle cable.

Yes, the arms are centered with springs in each end of the bar.

The only issue with arms to the rear is if you have a tall mount linkage - it may interfere with the trunk torsion bars- mine are gone as I’m using 944 rear hatch shocks.

An-10 feed?!?! Good grief, this is a 914 we're talking about, not a top fuel drag car...

Way overkill. You'll need one seriously hefty pump to deliver enough fuel at enough pressure if you use -10 lines...

Yes, I made it- 18 years ago. You can make one too. Some scrap metal, cardboard template (I'm big on templates) , hacksaw, drill, grinder and files. It got thrown into all of the parts that got cad plated.
