Ductwork

[Overcenter]

Here is some simple fab I did on my personal S13. The ductwork is highly effective in keeping temps down on the street and the track. The shape of the duct help speeds up the air as it passes thru the core face. By sealing up between the IC and the radiator my water temp average about 175-185F. It's a good addition to any car that is in a hot climate. Good job on the fab forum, its nice to have a place to come less the typical interweb drama.

This is a cheap and easy project that could be adapted to any car. The duct is made out of 6061 T6 .063" thick. I bent the curve in the aluminum by pulling it around a parking pole.

thanks Kevin, that look a treat and will be doing something similar to my car when the new motor and IC go in.

have you any shots with the bar attached to the car?

and regarding the seal between the IC and radiator - how did you run the mounting to give an idea to the rest of us

Noice1 Craved ! I think I'll have to put a lil' panel between the very bottom of my I/C and the bottom of the radiator, to stop air bleeding out between the 2 cores.

On the 37deg. trackday I did at winton, 3 hot laps in a row saw the water-temp up around 110Celsius plus ! ! !

just a side thought, wouldnt you be cutting off fresh air to the radiator as well? or do you think the air passed through the cooler is sufficient..

It wasn't really any better or worse. I was worried that air that'd been crammed through the FMI/C by the front bumper intake, would bleed out the bottom of the gap between I/C and Radiator - into the lower-pressure region behind the front bumper.

The PowerFC showed a peak water Temp of 116deg.C this time . . . . 8-O

116 degrees is way too hot - was this at a track day? looks like you need a radiator flush or a bigger alloy one
