'07 Exige S Fan Location

Just removed the front clam on my car to swap hoses, SS brake lines etc. etc. Plan on changing the radiator as well. A recent post of an Exige S clamless with an all aluminum rad has the twin fans on top. My stock rad has the fans on the underside. Is the top mount a better way to go? If so would I have to order a different year rad?

puller fans are aftermarket. They use the same radiator. If you are not seriously uprating hp and tracking, I don't see the point.

you ought to do your heater fan resistors while you are in there

The aftermarket puller fans don't have to use the same radiator. Mine don't.

After market puller fans are not as effective as the stock fans. Been there done that. No reason to change from stock. I've run 3 different configurations and stock pushers (with homemade shrouds) and a deleted AC condenser is the most effective cooling.

Last season, with a 400ftlbs/450whp compound charged set up, temps only got as high as 207 on a hot day.

I'm using a Laminova setup with a large aftermarket radiator and dual SPAL puller fans. Same setup as Jack's 211, except I have AC, done by VSA Motorsports. If you check their page they're using large pullers (single) on the Cup Rs as well. https://www.facebook.com/VSAMotorsports/

Racecars don't spend much time at zero mph which means their fans are mostly just in the way of the airflow. If you have a high output auto-x car or a street car, you need fans to do work.

I'd like to see some pictures of those homemade shrouds. My understanding was always this mattered more than the fan setup.

I didn't take any but basically, it's thick rubber riveted to the side of the fan shrouds that close down the space between the fans and the radiator. I've removed the AC condenser and reused the OE fan brackets, thus the need for shrouds to close back down that space.

I added foam even with the condenser in place for the same reason
