LS1 Fans vs Flex a Lites

[Sleaper]

Just like the title says, which is better? How many CFM's do the LS1's move? Do you have to get a bigger alternantor with the LS1's just as you would with the Flex a lites? Thanks in advance for the suggestions!

What about Spal fans?
I think the 145 amp alternater is a must for any fans but that is only an opinion.

If you have a system in your truck,I would go with the bigger alt...the fans will use all they can get

I don&#39;t have a system for my truck, but was told that a stock 105 amp alt will do for the fans only. Does anyone know the cfm&#39;s of the LS1&#39;s? Thanks for the input&#33;&#33;

I have the stock alt too. I&#39;ve got a 450.1 Kicker amp pushing 2 CVR 10&#39;s...with the Flex-a-lite 292 Monster fans and I have not had a problem at all. But then again, I have the smaller crank and alt. pulley. I am not sure is the smaller pulley allows for the alt to create more amperage, but with my system and the fans on, I typically run 14 amps on the gauge...

IMHO, I like the Flex-a-lite fans. Easy to install, easy to wire, etc. But they are more expensive than the LS1 fans. They are more expensive because the LS1 fans are typically a used set-up, where the Flex-a-lites are new... I know that the 292 (for the 28" radiator) and 282 (for the 34" radiator) push more CFM&#39;s than the LS1 fans do because of the fan size...



Once you do get fans, a Nelson fan harness is also an option...

Thanks&#33;&#33; I found a good deal on some LS1&#39;s fans that I will try and I already emailed Allen for a harness&#33;&#33;
