415HP from 318ci IS POSSABLE!!
Shady Dell's RPM heads flow 288 at 28" and .550 lift. I am not sure of the volume. the flow was verified within 3% by a local shop and a different bench/operator. On the dyno (two independant ones actually because we were chaing an oiling problem and the first shop was being a twit), the 408 they reside on peaks at 114%VE at 6K, it passes 100% at 2800. It makes 557hp at 6500 rpm with a solid roller of .600 lift and 92 octane. The car it's in is a 3400lbs car (all steel car, mild steel cage, mildy overweight driver :D, 727, used NO2 convertor) with 4.10s and 28s that runs 11.20s on motor with 115° track temps(Vegas). This is a modern custom roller by Ryan at Shady Dell and it needs the reliefs with the 2.02s. I didnt build this one, nor have anything to do with machining other than direction from CT to CA on what they needed to do. This is why I say I see issues with your physics. Physics easilly can cover why the readings go beyond 100%. You already know this and you're just being cute now...lol. With your commenting that you may have moved beyond physics I guess it's time to just say "ok". I can compete with imagination. So, Ok Bobby, I will trust completely that you know more than any other person on 318s and 302 heads and getting Top Fuel results on a specatators budget...lol :D.
