Default Residual fuel in intake, normal?

About to hit the dyno tomorrow so I put 100 shot jets in and did a pull. Car went good. Good AFRs, linear power increase, super low timing.

Got back to the shop and pulled the intake and noticed there was residual gasoline in the throttle body/air intake. Not a lot, but def there.

Is that normal for a wet shot?

I would think so since you are spraying both nitrous and fuel before the TB

I agree, I wasn't overly concerned, especially since how well it went.

But in just wondering if anyone else has noticed that

That doesn't sound right. Any gas that may not immediately get sucked into the intake should evaporate very quickly if exposed to airflow. I would check that the fuel noid isn't leaking by giving it a quick test signal and see if the gas stops afterward.

If it's leaking a little then you'll need to replace the piston in the fuel solenoid.


It looks like you're using some of our solenoids on the setup. If you'd like to give me a shout here at the shop I can go over what it would take to get those rebuilt/checked. That away you can have a worry free setup.

I keep checking the noids for leakage, but it seems to be fry even at its highest fuel pressure.

I assume the only reason the lines/noxxles dont empty them selves is because they should be tight to create a syphon.

Im wondering if one of my lines coming from the noid to the nozzle is not sealing right
