looks cool but i think its going to be sucking in too much hot air.

I think if you extended them further toward cooler air it would be worth it... ur just sucking in a ton of hot air..
Whats your IATs?
Prob alot higher than most FI guys..

Friend tried similar thing..sucked in too much hot air & pulled a crapload of timing due to it..it ran like crap till he changed it back to the normal location behind the headlight.

Looks cool though.

Hahaha, I've been running without that cover on the radiator for who knows how long and never even got close to higher than normal temps... I don't know if that's the sole purpose... Just makes it a little uglier.

looks good man, too bad there is no dyno results

I understand how the cooling system works. I titled the thread "hot air intake" as kind of a joke.

Lots of B-body folks run similar set-ups just fine. I did mention that I will eventually build a heat shield and run scoops from in front of the radiator. Or maybe route some tubing or piping over the core support and put the filters in front of the radiator?

I have no idea what my IATs are. I would like to find out though. Thechevyman122, do you have a scan tool or some way to read it? If not, maybe I can get somebody to ride with me with this setup to compare IATs and MAF readings with the stock intake with a K&N drop-in filter.

I have been able to get really good mileage with both setups though. There seems to be better throttle response and power with this compared to stockish.

And honestly, I don't really care for the chrome. I'll probably paint that with black undercoating to help reduce heatsoak from the aluminum pipe.

I do agree with the dyno results. I have a baseline from the stock intake with the only other change being switching from the stock 245/70R17 Generals to 275/60R17 Cooper Cobras. There was a noticeable mileage reduction with the shorter and wider tires.

I made it through the Texas summer with it like that without any cooling issues. I still have the stock thermostat and electric fans. There is a lot of grille area to get hit by air.

I would extend the tubing out closer to the fenders, then put some header wrap around it...

Build some air boxes if you want...

looks good but would be nice if the tubes were longer

When I saw this post, It made me think about my AEM CAI. I was curious about IAT's and my AEM CAI, so I did some scanning last saturday. Stock airbox and filter, IAT's hover between 90 and 100 degrees. I'd say it took about five to ten minutes to get the IAT's over 100 degrees. Ambient temps were about 85. It took about five miles of driving at 55 mph to get the IAT's back near amibient, lets say 86-87 degrees. Next I tried my AEM CAI. Ambient went up to about 86-87. IAT's after five minutes of idling were 127, but after driving at 55 it took about 2 miles to get close to amibent, about 87 degrees. To sum it up, the stock airbox will take longer to heatsoak, and raise the IAT's. But it took longer to cool off. The AEM CAI, got a lot hotter, quicker, but it cooled off in half the time. For the driving I do, stop and go, a lot of idling, and short trips, the stock setup or a fully enclosed CAI is better. For someone with a lot of highway driving, I'd say go for the AEM setup or the open style. I don't mean to jack your thread, but I though this might help give you an idea regarding the IAT's.

like I said, I KNOW IT IS SUCKING HOT AIR NOW!

IATs will go down when I get the box finished.

I have a feeling that the hot air helps fuel economy.
