D3PE, here's a setup I made for my car. Much more room for superchargers and can be cut down 2" for the dewitts radiator. I was able to move the fans out and down because my shroud sits on the edge of the tanks instead of the inside. No shown, but I clocked the left fan motor 90 degrees for more clearance on the sway bar. Making them this way, might appeal to a bigger market.

Totally different fans. Different power setup. These probably flow 2x what the spal downgrade fans flow. What you have moves less air than stock.

They're the same 11" extreme HO fans they use and same relay.

No they are not. If you are talking about yoursetup posted above, yes.

He is talking about the off the shelf spal dual fan setup.

Default You need to look at these under load

This dual fan set up here by D3 flows 2,680 cfm (1340 x 2) at 15 mm of restriction whereas the spal 2 x 11 flows 1,770 cfm. So 50% more flow using the 15 mm restriction. However does take more current 56 amps versus 35 amps. People get caught up in the free flow that has nothing to do with it (unless you have nothing in front of it). These cars have a radiator, ac condenser, oil cooler, and intercooler for some people - this all causes restriction and can severly eliminate flow from a low powered fan. In fact at 20 mm the difference is even more with only 1263 cfm for the dual 11s versus like 2400 cfm for these - pulling 60 amp though.

My C6ZO6 set up is DeWitts radiator with the Dual Fan Upgrade ( Total cfm 2760 ). So if I would go with your Dual Fan set up by D3 the car would run cooler then my set up?

Only if cooling at low speed/idle is what you are going after. Once your moving, fans are doing very little, so if you are going for cooler while cruising on the highway at 75mph, then no.

Like posted above, CFM without a restriction means nothing.

I'm going after idle at traffic that my concern. Since I don't I use my AC I removed the Condenser and I think I have less restriction.

If my car runs around 225-245 with AC on in 100 degree weather cruising at 80-85mph, how much should my temps drop after installing this setup?

Car is a ERL 427 with a Novi 1500 and ECS SC intercooler kit.

Default 80-85 mph

The fans will not help too much as Unreal said by that speed the air should be pushing through at that point. The D3s are very helpful for under 40 mph with all that stuff you have in front of it. No one thing I noticed on mine is that it runs cooler in 5th gear than in 6th by about 10-15 degrees in that speed range you are talking about. I am not sure if it has to do with water pump speed or the engine lugging at a lower rpm but it runs cooler in 5th. Now I am naturally aspirated.

Great info in this thread. I have an A&A t-trim kit coming for my c6 z06 and I am looking to upgrade the fan setup. I know that A&A's kit comes with a different radiator (not dewitts) so I was wondering if anyone knows if this will fit? It's slightly thicker but not sure on size. If I remember correctly, their kit does utilize the stock fan units, just not sure how much modification is necessary to get that on that would need to then be done to this kit. Thanks for any help as this restricted flow increase will really help me in the summer down at the beach and slow cruising in traffic.

Is D3 still selling the fan setup alone and if so, will it mount to a Dewitts shorty for a ysi application?

THis looks to be the ticket for those hot 117+ degree days here in Phoenix

Would be nice to know if D3 Prospeed is making a version for shorty Dewitts or if badass68 wants to make me one.

Man, I wish I had time to make some. At the moment I'm way busy. Maybe in a month or two I can make it happen.

They released a short radiator version, but once again, no reason to run the short radiator for a street car. Stay full size with this fan.
