Thanks for the info David, I wonder if you might be able to weigh it when you get a chance. I was talking to Chad Block about his new rad/fan setup and he only knew the weight of his entire rad/fan vs stock and did not have the weight of just his fan. But with a bit of math we found that his fan weighs 1lb, but that seemed too light to be true.

I do see the 12" fan on your site. You also have a 9" listed there, do you think that would be too small?

Hey would you happen to know the approximate accuracy of a CAT scale?

 

I would guess they are not that accurate. I mean you are talking about weighing vehicles that are several tons and where 50 lbs really means nothing.

I have gone to the scales at truck check points before and have found that they can be within maybe 30-50 lbs or so.

The scales at the race track are much closer, and finally corner balance scales are what I base these comparisons on as I assume corner scales are spot on.

 

In this thread there is a link to a 4.5 lb battery:

If you have the money this could shed 10 or more lbs from the other lightweight batter setups.

 

yea i saw that battery a couple weeks back. I spoke with the company to try and get a discount, they gave me a better price, but its still way to expensive. I was thinking of going with the lightest of the decka batteries but I don't think it will start the car in cold weather.

My current battery is 12lbs, I want to find a lighter one but $100 is about my limit.

 

Stock radiator only 9.7 pounds, very freaking light.

Small radiator, Fluidyne, that we sell when using a BIG turbo, 6.8 pounds.

 

DB/Dudical/Fred- I know the stock fan and shroud weigh a lot. My question pertains more to the fan controller - Do you eliminate it when you swap to a lighter fan? What is the purpose of this controller and can it be eliminated....I would much rather do that if I could. Its such an awkward piece...Thanks!

 

We do not eliminate the fan controller.

 

I have heard that everyone keeps the stock fan control unit. I have read into what the fan controller actually is and apparently someone dissected it and found out that it is basically just a couple relays. They said that it had a two speeds for the stock fan. I don't remember if the person actually replaced the unit but they said it could be replaced with a simple relay.

The fan controller is kinda bulky and might weigh a couple lbs, although I've never weighed it.

Second post has a wiring diagram of the controller. Basically it can be replaced with a simple relay, much smaller and lighter. I broke my scale, any one wanna get a weight on the fan controller?

 

Yeah I got nothin... I did take the front bumper off to measure somethings for an oil cooler project and in the process took out one of the horns. Still plenty loud with just one.

 

Thanks, guys. I wish I knew more about electrical stuff to wire up a relay. I am pulling AC on the car, I think. Keeping heat, though for defrost use.

I am considering using 2 pusher fans instead of 1 puller and thus eliminating the fan on the inside which should provide ample room, I think.

 

Why do you want to eliminate the inside fan?

I pulled my AC and the pusher fan. I am going to be replacing the stock puller with a slim line puller.

I don't think you need two pushers.

 

for turbokit clearance - I am planning on going fluidyne - thicker (CBRD seems nicer, but worried about road race use) and just having 2 fans on the outside to allow for more clearance with a turbo kit!

 

Do you really need a fan if your just road racing, I thought fans were really for sitting in traffic or stop and go driving.
