I just bought the Zex kit, and was wondering if anyone has had the NOS RPM Window Switch adapted to their ZEX kit.

With this setup I could keep it from spraying off the line (to avoid wheel spin), and keep it from spraying while my auto shifts.

 

For those interested, I talked to Holley.com and they mentioned that this can be done. For just under $200, you can get the modified RPM window switch that works in conjuction w/ the ZEX kit.

Results: you will have to be at WOT and w/in a certain RPM range for the kit to activate. This allows for even more control over when you spray.
