2500cfm is weak for the size, and that one is probably too wide for our radiators. I'm going to try and squeeze dual 12" fans onto a custom shroud, not sure if I'll be able to get them in or not. I think Rangerbob had the measurements in his e-fan thread, and I'm pretty sure our radiator was 23" wide in between the end tanks.
When I did the shroud for my SPAL installation, the height (between top and bottom tanks) was 18" and width was approximately 24" between the OEM shroud top hanger hooks.
A friend of mine with a Colly here in Ontario, has the exact fan, and he's happier than a pig in shit.
If you are interested, I can get those fans for like $20 off the price you see on PerformanceCenter. And their shipping is only like $11 or somehting, cheap.
Will these fans help or fix the rises in temps that I seem to be having out here??
What I mean by this is; I'm running 20's that are 9" wide. When driving on normal flat ground or slightly hilly everything is fine even with the A/C on. But as soon as I start to climb any type of hill that's slightly higher grade the temp goes up with the A/C on OR not. Now "normal temp" on "my" truck is just a hair under the half way mark. By the time i get to some of the hills out here it could get as high as damn near 3/4's. IMO I think it's getting to high. It used to do this with the stockers, the extreme 18's and now even worse with the 20's. Now I do understand bigger wheels more weight etc. etc. so it will go up a little. It's just that it went up even stock.
