318 in the tens
Something else to ponder..It's much easier to go from 13s to 12s, then 11s to 10s. If you're running say 13.0s, and 150 shot get's you to 11.80s, that's 1.2 seconds faster. If you add another 150hp, you will not get the same "amount" of ET loss. Because it takes a bit more to get faster at the 11s level. You may only get another .8 out of it. I dont think 50hp at the 11.80s level will go much faster than 11.40s, assuming all traction and stuff stays the same.
