Quick Question

[sdcarguy]

I installed my AFE this weekend and it was great until I got out of the truck just now and when I turned the key off you could hear it continue to pull air for a good 5 seconds. Its never done this before and now does it each time. Anyone know what its doing? It almost sounds like the turbo is slowly spinning down and pulling air...

The truck doesnt have anything but the AFE currently

no spartin or straight pipe? mine does it too, and i have the same intake. but i assumed it was the exhaust.

where are you at in san diego? it'd be nice to see another spartan truck

Just got all the other parts yesterday and was going to install this weekend. The afe went on last weekend. So its bone stock except the AFE. Well at least someone elses does it to. I just started the truck and when I shut her off it made the sound for a good 10 seconds and sounded like it was ramping down...

Im in between el cajon and la mesa...

gotcha, im out in mission valley until november when i move back up north. tip on the exhaust, start lubing the egt sensors early, be careful with the pressure sensor, and take your time.

yeah im hoping with only 1500 miles they wont fight to hard...

It's normal

Since you put the afe on its letting you hear what you couldnt before. Its not really doing anything diff its just that you can hear it cause its not baffled by the factory air filter and the fender vent.

Yeah thats what i was thinking it was just really weird that i didnt hear it for the first 5 days its been on then to hear it tonight. Thanks for all the replies!

The sound you hear is the turbos spooling down. If you were spinning at 20,000RPM, you wouldn't want to come to a sudden stop either. It's normal and I think it sounds pretty cool.
