Taurus fan

Anybody have the Dimensions of the taurus fan. The depth or clearance I need between the radiator and the motor is what i'm after. I have the ron davis radiator and i think a spal fan. It's just not cutting it (or cooling it) here in july in orlando. The fan I have is pretty low profile and i don't have much room. The pics i see of the Taurus fan make it appear to have "thicker" motor.

HUGE!!!! I had to cut my front nose panel and slant it forward. [You must be registered and logged in to see this link.]

Thanks - I thought I saw that somewhere

The inches are the radiator measurement, but there should be enough for you to figure out how HUGE that sucker is.

Here's a web site that might be helpful in understanding why a car with cooling issues can greatly benefit from air being ducted to/from the radiator properly. [You must be registered and logged in to see this link.]

If you look at the demonstration window and create a flow that starts small, opens up, then chokes down again, you can see how the flow volume is the same, but the speed can be manipulated. Think of the NASCAR Cup cars with a small opening in the front facia. Air enters in at a high speed, then slows in the cavity that contains the radiator, then picks up speed as it exits. The slowing of the air gives it a chance to absorb the heat. The volume of air entering and exiting is equal at all times.
My 914 V8 only used the fog light openings and the space between the bumper and air dam to let air into the radiator housing we built. The car never overheated, even when tracked, idling, or in street traffic.

late 90's 2 Speed for those with AC Fits the 944 space fairly well lows on with AC and low temp

high only only with high temp by using a late 944 rad temp sensor made for the 2 speed Porsch fans

Stupid question: Why not just use the 944 rad and fan setup?

944 radiator and fan would have a hard time in hot climates (impossible with a N/A radiator). I have the Ron Davis radiator (which is much larger than the stock 944 radiator) and it had a hard time cooling my LT1 in summer heat (w/ no a/c) (it stayed at 210-215 with the fan on) with the fan that RH used. I put the taurus fan on it and on the LOW speed setting it keeps my car at 180* at 100+ temps. The car actually gets hotter on the freeway when the PCM shuts the fans off over 45mph. But that only happens in "dirty" air.

If that above fan works in the space, you can use the lows and the high's from the LT1 PCM very easily. I wouldn't use that stupid fan switch in the radiator....

In my 355 V8 S10, I just left the stock 2.8l radiator in and ran without a thermostat. That thing NEVER over heated (avg. @ 160-170*). In the winter, I just reinstalled the T-stat. I'm going to try this when I get there and see what's up with the NA radiator run this way. In 104* temps this week it would have been a good study.

hey thanks for the help. The turaus fan looks to be too thick for my car (i can't tilt the radiator without a lot of work) The concord one looks good I'll need to find the thickness. I'm going to work on some better baffleing/duckwork with what I have now. The single fan that comes with the RDavis radiator doesn't cover the whole thing and i got some space on the sides that probably should be blocked. I'm in orlando and am gonna need to hook up the AC at some point. It's hot and I'm getting old. I have the fan controller from dakota digital which works great and can control 2 speeds I think and turn on with the air. Works great in the winter. The original porsche fan is too thick with the RDavis radiator.

I also am running the taurus fan (actually its the licoln MKVIII fan) and also use Eric's(admin here) tubular crossmember. Its a sweet thing.

See theres this nasty triangular xmember right in front of the radiator in these cars that just block and redirect air flow. And its huge! So, Eric makes these tubular ones that really help the air to get to the radiator.

Heres a pic of what I have. The lincoln fan fots perfectly behind my radiator (ron davis) and is the same dimensions of the rad as well. I guess my fan is a bit smaller than Tim's.

Thanks for posting the pic, I have the same thing in my car with a stock turbo radiator and the Taurus fan, It runs 180 all the time

That looks like the ticket but...... time is my enemy right now. I can't see having the car that apart now and then getting back together any time soon. Switching a fan doing some baffle work is even a push. I'd rather have it in the garage running as is for the next 6 months than sitting in the garage in pieces again . It would just piss me off. And.... there's no air in the garage... and then my wife's personality will go all to s**t. It ran great in the winter.

I picked up an intrepit fan. The thickness is good but it looks too wide. Has anybody used this with a ron davis radiator? Before I start chopping it up it'd be nice to if I have a good chance of it fitting. The input and output for the radiator seem to be problematic.
