Frequently Asked Questions
-
Q: Will this kit work on a non-LT4 superfcharged engine?
A: This kit is specifically designed for GM LT4 superchargers and includes a billet LT4 lid, retrofit to other superchargers would require custom adaptation. -
Q: Can I run just the nitrous and skip the water/methanol portion?
A: Yes, the system is built with both; however, using the water/methanol portion will help cooling and may reduce detonation risk under higher boost/power levels. -
Q: What tuning do I need after installation?
A: A proper tune or calibration is essential when adding nitrous or water/methanol systems. Consult your tuner to adjust fuel, timing, and boost mapping accordingly.
Shipping & Handling
