The biggest Single SPAL Fan I can squeeze in?

I am going to take off my front clam and I want to take this opportunity to redo my fan setup. To minimize down time I've been doing some research but I cannot be 100% sure what is the biggest fan I can squeeze in - I dont mind cutting some not visible structure.

Current Setup: Exige S
AC & Pro Alloy 3pass & Sector111 Dual top mount fan

Fan is SPAL VA07-AP7/C-31A measuring
Depth (Motor) - 2.011811 Inch
Depth (Fan Wall) - 1.10236 Inch
Diameter - 9.68504 Inch

I plan put to bigger fan in under the center Spine. Can someone please advise with AC and Pro Alloy, what is the single strongest fan I can put in.

I looked at SPAL web and I guess I could squeeze in a 11-12" diameter, ~3.7" depth (motor) fan.

re: biggest fan

And why do You want to do this?

Is Your car running very hot at idle?

In other words, why bother, if what yo have is sufficient?

Two pullers are better. I use 2 SPAL VA07-AP12/C-58 12V.

I used a single Spal 30101500 11" Straight Blade Low Profile Fan -- It was the biggest that I could make fit. It took a little bit of dremel work on the fan cage to get under the shroud on my Exige.

It works very well, pulls the temp down 15 degrees in less than 10 minutes at idle, don't think a dual fan system would do any better.

Maybe you didn't read my post. Dual pullers are better. They cover more area and are more effective than a pusher/pushers. If pushers were better I'd still have them.

Not sure why you say the dual system is better, but I know the single 11" puller on top works very well.

Because I want to it to be optimal for track use - the fans only block airflow at high speed. Thus I only need 1x fan to hold the temp for road use, in a traffic jam.

Thanks Ron. Finally found help. I have a few questions.

1. Is your single 11" placed in the center, under the spine?

2. Can your single 11" hold the temp in a traffic jam? ?n what ambient temp?

3. Which part of the cage do you have to cut? Is it the end towards the front of the car because the clam slopes narrows.

4. How much more clearance do you still have at the center of the motor?

5. Can you take a pic with your cellphone and share so I know how much clearance from the side you still have.

Thanks alot!
