There is a big difference between Raw HP and usable HP.

Port Timing has a lot to do with this and like Jonothan said the prof is in the puttin. I run the "Argus" box stock in my truggy. i love the way the power comes on and there is plenty of it. the engine is fast with all of the grunt i want, right where i want it. My old truggy motor, a highly modded "Vspec" (witch i am sure would put up Dyno numbers with any motor out there) is sitting in a draw in my trailer.

the "Argus" A52 is my choice for this truggy season
