The Blue pump is more than enough for the smaller plate systems. 100hP is well within the reach of those pistons, but you really need to know what the ring gap was set at. KB recommends lots of extra clearance, due to the piston's high top ring land. If this was done, you're fine. If it wasnt, you may not have had any problems, but you may with any NO2 system use. Follow the kit guide lines..retard timing 2* for every 100hp, and make sure the fule pressure stays over 5psi WITH THE SOLENOID OPEN. I ran as low as 3.5 psi in my 150hp kits, but leaner means hotter, and more chance to detonate..You'll really understand detonation if it happens with those pistons.
