The engine is a monster. I have not seen another 12 that will pull on it on the back straight. It just seems to run away from all the other 12 and 12 modified engines. Great engine!
It depends also on tuning. If you tune better than another guy (maybe he's rich or something) then obviously it's faster. I think that people put way too much emphasis on getting a high power engine. I do it too
Anyhow, I just thought I should mention something about that.
