Mystery modification!!

gchemist · 06-19-2008, 07:50 PM

I started work on a mystery modification. I only had my cell phone for pictures. Here is a tease picture.

I'll post the rest after it's complete. Hopefully tomorrow!

Home made Intake. Good luck, post pics

gchemist · 06-20-2008, 04:27 PM

Stealth ram air intake for the 4.3!!
What ya think?

I finished the installation today. I'm driving nearly 150 miles this afternoon. I should get a good feel on how it works. I hope to increase city MPG to 19+. The Jimmy averages 18.5 MPG since PCM programming.
The snorkel costs $17.50 at a local performance shop. I had to buy some 3" hose clamps. Everything else was sitting in my garage. The black hose is actually race quality brake cooling hose. I used it on my 83 Chevy ram air intake too.

I had an intake on a WAY dropped 91 Civic hatch Si thats filter was about 4" off the ground, with no skid or bottom plate. And never had a problem... Sold the car, it now has a b16a1 in it with the same intake setup driven as a DD and still no problems. Ive heard of people hydro-locking engines with intakes...But I guess I was lucky...

sonomanator · 06-21-2008, 01:59 AM

aem sell something to stop the water.

last year on the way back from itb it was pouring rain the whole 10 hrs home. the 2 other trucks i was with both had no inner fenders with cone shaped filter right by their tires. neither one had a problem.

that bullshit....my blazer has no inner fenders and i had to make a shield to deflect the water off the filter cause it ran like shit cause the filer sucked in water

gchemist · 06-21-2008, 10:30 AM

I love doubters.I have this on my 83

I've driven it in rain. It's carbed. Absolutely no problems. Who can complain with 18.5 MPG with 365+ horse power! Ram air works.

Take a look a the filter housing. Wonder why GM enginers installed a box with the filter located at the top. Any moister (actual water droplets) will fall to the bottom. A small hole at the bottom will let the water drain out.

As people complain about gas prices, why don't they do something about it. I'm not driving less. I'm making my vehicles more efficient.

Yogi · 06-21-2008, 12:10 PM

Looks like a good set-up! I only have one complaint.

When you hooked the hose to the airbox, it looks like you used the stock snorkel for an adapter. That snorkel necks down to only a 1.75" opening which is very restrictive. I did something similar (click here) but I took off the snorkel and ran 4" tubing into the airbox.

Nice looking mod!

gchemist · 06-21-2008, 03:55 PM

I wanted to cut the original snorkel. However, clamping the hose was a problem. I do plan to look for a 3" option. A 3" snorkel replacement would take better advange of the setup. Next time I'm at homedepot, I'll try to find a nice 3" adaptor to fit.

At least the K&N filter will stay cleaner a little longer. I installed new oil cooler hoses a while back. Unfotunately they leak. The stock setup sucks. I need to find a better option. I'm happy with the air flow. I noticed the engine ran a little cooler too.

Yogi · 06-21-2008, 04:10 PM

I used 4" clothes dryer flex duct and cut out a hole in the airbox to fit the duct. After fitting the duct I caulked the joint with RTV. I think that between the friction fit and the RTV that the duct is not going to move.

I think that Home Depot has 3" hose connections in the dryer duct and vent supplies.

gchemist · 06-22-2008, 10:18 PM

Thanks! I'll check for 3" dryer duct.
