BillR1212- I am not running a Sniper, but am running a Holley throttle body with multiport ran by HP EFI with Holley's water methanol kit. I have water methanol injection nozzle in the carb hat and it works well. I have had an instance where the injection did not come on and I think I saw similar temps of around 140° F, but typically see high 90s°- 103°F during a 1/4" mile pass.
