OK, I did search, and couldn't really find anything.
My basic question - when does the 914 2.0L intake become a restriction to power? I have a built VW 412 - 2056 cc Type 4 * 9550 RAT cam * LE-180 heads (914 2L combustion chamber, 42mm intake, 36mm exhaust) * Mallory Unilite vacuum advance distributor, Mallory Promaster coil, Mallory Hyfire CDI * Stock 412 heater boxes & Thunderbird exhaust * 2L Bus plenum and throttle body * 2L 914 runners * Ford "Design II" F1TE-D9A (Bosch 0280150947) 24# injectors (modified) * SDS programmable EFI * Oil bath air cleaner housing modified to use large circular filter element I have a pair of IDF manifolds, and some VFR throttle bodies. Roughly equivalent to Weber 40IDFs (maybe a bit better in terms of flow). Engine made 115hp at the wheels. I'm just wondering if the (improved) stock intake is a cork or not?

I don't have any current ones, really, but I'll try to take some at the shop. The paint has faded since these and there is a parking lot bump in the left front corner, but you get the idea.
EVERYTHING in this 412 has been upgraded and built. The trans was rebuilt, all the bushings were replaced with custom delrin, bronze steering bushings, BMW E30 M3 front springs, Audi 4000 front struts, double rear sway bar, Porsche 944 brakes all around, etc etc etc. My plans are to install a Scheel drivers seat, better looking wheels (may require flares), fix the sheetmetal a bit, and drive it. May eventually sell, but it's a fun, unique little car. (IMG:https://i61.photobucket.com/albums/h43/greggearhead/VW%20412/73%20412%20Coupe%204-speed_zpsqlqx1tap.jpg) |
