Gott's mod, 2nd version
 

Hi all! First post on the forum since getting my 07 s-crew (courtesy of a little old lady who ran a red light and totaled my Vic right before Christmas).

Doing some upgrades and decided to do a cold air mod. I went to Lowes fully intending to do the Gott's mod to the letter. They were out of stock on the PVC, but I found another solution that seems to work just as well.

One piece of flexible exhaust duct. Note - this is NOT dryer vent! This is flex aluminum duct meant for hot exhaust ducting. It's crenellated solid aluminum, not spring-loaded aluminized plastic. I found it in the (gasp!) vent & duct section.

The coupler was over in the PVC pipe & fittings dept. It's a rubber sleeve wrapped by a stainless outer sleeve and two worm clamps. Came in the exact size to fit the ducting. It's also the exact same size as the end of the intake plenum.

Except for the PITA it was to get the air horn and flex link off the intake, installation takes all of about three minutes. The flex duct must be reshaped (i.e. squeezed) ever so slightly to make it fit but is otherwise the same size as the opening in the fenderwell. The coupling must be expanded to it's maximum to fit the plenum but slips on without any undue gyrations.

The only warning I have is to take your time trimming the duct length. I got a little overzealous on the first try and crushed the tube. I also left the tube completely collapsed into the crenellations to keep it as strong as possible. I tried expanding it but it became a lot flimsier that I cared for. 60 seconds with a pair of shop shears (or even heavy scissors, for that matter) is all it takes to get the length right.

It's not as slick as the "real" Gott's mod, but it works.

Looks good man. Welcome :)

w/o that being smooth on the inside, the turbulence is screwing up the velocity pressure.

Better than stock!

Nice work. Totaled your Vic...are we talking Vic motorcycle?

^ I'm voting Crown Vic

Yeh what he said I also vote Crown Vic as the victum.

I also hate to steal your thread but for my mod on my 04 I just used a 4" outside diameter schedule 40 pipe 8" long, sanded the fender end to fit in egg shaped opening in the fender and hose clamp around other end. total cost $2.78, time 15min.

definitely crown vic because who rides a cycle in winter? and who gets in a cycle accident and lives? Very few

My auto teacher when i was in high school got side swiped by some old broad while he was going 65 down the highway, all he had was a little spring in his step for a few months haha, he got lucky, the bike was totaled.

back in '87 i killed a 9pt bike on my hurricane 600

That would be me. On both counts. :coffee:

Been riding for over 40 years ... and am still here to pester y'all redneck youngin's :lol:

OP - listen to Phil. He knows his chit. You want smooth internals. Aluminum is a very poor material to use due to heat transfer. PVC is a much better choice. Smooth stainless, polished on the outside and dull on the inside, is best. It's been shown to shed heat fastest after a heat soak.

Lots of people ride motorcycles in the winter time. I know of many.

More people get in motorcycle accidents and live than get in motorcycle accidents and die.

25 years of riding motorcycles and have 3 deer kills with 2 gsxr1000 and 1 sv650.
I'm still here also but the bikes arent.
Winter is a PIA around here but I still ride my Harley when I get the chance.

lol ok sweet. Even in the 10 degree winter weather? I have never seen anyone on a bike this time of the year up here.

Well thats good to hear. The past 5 years i've mostly heard of deaths on bikes,though other people up here drive stupid.

Yeah, I sure as heck wouldn't ride in the winter. I have no windshield on my bike so anything under 60 degrees is cold for me. The guys with the heated seats and grips will ride down to around 30 degrees as long as there is no snow/ice on the road.
