Race gas vs pump gas on lower compression street/strip motor

I was skeptical when I built my first low compression S/S nitrous engine on pump gas, but I've since built several and have become a big fan. Low operating costs give me a lot more seat time than my race gas buddies, that I see as the biggest benefit.

My current one is 4.03"x3.48" 9.36:1 static. Solid roller 251/261 114 LSA, flat tops with .084" quench. Dynamic varies quite a bit depending on the calculation method, but it pumps about 100psi on the starter. Set of 342cfm Brodix -11RI's w/ titanium valves from a 360 sprint car. Never been on a formal dyno, but I ran the spec's thru somebody's calculator at one point and it said 549hp NA @7473rpm. Down on NA torque vs a higher comp engine for sure, but how much torque do I really need driving around on the street when the car weighs 2525lbs with me in it? It gets 20mpg on the highway with locked timing, manual trans, 3.73 w/ 28" tires, no overdrive.

When I pull up to a spot where I want to stretch it's legs, all I have to do is reach behind the seat to open the valve, then flip the switch to arm the system. Currently spraying around 250 on Shell 93, plenty for the backwoods no-prep stuff that I like to do. That little low compression 355 really comes alive when I hit it with spray.
