Does anyone know where i can get a decent duct that will give a good fit for my greddy smic??

Pettit has a duct that will fit (with a little work):

Also PFS used to have a duct that would work as well:

You'll probably need to email them or get them on the phone.

 

It doesn't come with a duct because it's intended to be used with the stock ducting.

 

dude- use the pettit. Make sure you use some good weather stripping + ABSOLUTELY make sure you use a torch to reform it to fit perfectly. I cut off the flanged area and remolded the fiberglass and it fits in such a way that Greddy would be proud.

Keep in mind that the pettit form is old for the duct and one of the sides is collapsing and results in a 3/4 inch warp on the duct (battery side). Using a small kitchen/utility torch fixed this perfectly. Can't tell you how happy I am. Covering 99% of the duct area with a 95-97% seal. I also formed a plate for under the SMIC to redirect the radiator heat. Coupled with my SPAL fan I don't imagine a SMIC this size performing much better.. (well nitrous xpress is always an option.)

 

I have the stiock duct but I don't think it lines up or fits very well. Was thinking that the intercooler would work even better if I had a decent fitting duct.
What is the little work required to get a pettit or pfs duct to line up ?? I'm really looking a for a flush fit all the way around. Too busy to make one up myself.

Get the Pettit, buy some weather stripping (not the 90 degree variety), cut off the flanged side (intake side) off. Use a mini tourch to tune the form.

Don't cut off the bottom flange as this lines up with the IC and helps shield some radiator flow.
