stage 1 Rotrex Supercharged 90 s2

Strapped her down on the dyno today..... 240hp at the wheels = 275 at the crank
This is a very safe, simple, inexpensive stage 1 setup with a 100mm pulley on a Rotrex C30-94. Stock injectors, Ostrich 2.0, and Gm alternator to make room instead of that bulky heavy original one.
Dyno sheet says 3.5psi, my gauge said 4, but whatever. Both runs were almost identical, even blowing the o2 sensor out of the exhaust.
The stock injectors are limiting the boost that can be used. We are pretty much maxing them at this point. Stage 2 will have 36lb injectors, an intercooler, and twice the boost
