Available nitrous plates for the SV1 that do not require a spacer under the SV1 for blade clearance are:
1. HALO for the SV1 (# 22750 for 95mm blade and 22760 for 110mm blade)
2. NX Gemini Twin (Use the 4150 for the 95mm blade and the NX# 60570-00 for 4500 bolt pattern intake)
3. ZEX Perimeter (use 4150 for 95mm blade and 4500 fits all sizes).
The Halo has made some great power to the 500 h.p. level and the Zex is good to about a 350 shot
The NX Gemini is a solid player for the 150-300 range
