AT Power direct to head Ford Duratec Throttle Bodies. Ran on a modified duratec 2.0 engine at Scholar Race Engines to compare to other systems available. The graphs show our straight 42mm system making 268bhp, and the tapered system with 50mm trumpets making 271bhp. The 45mm conventional throttle bodies made 263bhp.
Sorry I didn't get any high load video, I was busy watching the screens.

Honda K20 Throttle Bodies engine
Same Z-Cars mini. Aparently this car ran 220bhp before we touched it on
another rolling road, but the RR we used said it was 196 (different RRs,
different figures I guess?). Anyway it was upto 231 atf on the lower
reading RR, with the injectors at 100% max duty cycle at 3.5Bar fuel
pressure. Gives an indication of what it might make on another RR...
Sorry about the imagine quality, was pretty dark in there!
