Re: Cooling

I have entered, its a 1966 Nova with a Automatic so you can put the cooler in it before you send it to me. Thanks

Re: Cooling

How do you determine what radiator is needed when you are going to step up to a kind of racing where you'll run at or near full throttle for extended periods of time, think Silver State Classic. Currently I run an older single pass two core aluminum radiator of approximately stock size along with a Ford Mark VIII fan, 55 GPH water pump. Engine also has an Earl's oil cooler which hit 200 at about the same time on the road course.

Its fine for drag racing, cruising and has stayed within 200-210* for 3-5 lap road course runs at 9/10th's. But I don't think it'll be good for a 3 mile LSR course (dry lake) or the Silver State. A think a change will require some surgery on the radiator cradle so I'd like to get it right once. The engine is a 582" BBF that makes approximately 900 HP.

Recommendations?

Re: Cooling

Interesting question. On cars I've seen cranking out around the HP (usually less) that you do in the silver state have HUGE radiators alright, look like 4 or 5 row aluminum jobs. The BeCool website says after two row the efficiency of the air flow through the radiator drops off, but it may be off set by the higher speeds?? I think the record holder's engines crank out around 800HP and that's right at peak to make 220mph, iirc.

Re: Cooling

Distilled water or deionized?

Re: Cooling

We have a few land speed and roadcourse customers that run about that kind of h.p and they have reports of running between 185-195 degrees. Our radiators with the proper fan size and cfm rating we cool anything from 400 to over 2000 hp. Be Cool also now has a biodegradable coolant that is ideal for anyone with any kind of hp rating. With self sealing capabilities for cracks in engine or cooling systems and a 7 year or 300,000 mile life expectancy. I have personally put it in every vehicle i own as well as all of Be Cool company cars, and a friends 04 ss truck with a leaking water pump, drained the dex cool out and replaced with Be Coolant and 8 months later no leaks. Also saw a collant temperture drop with this as well. If a custom application is needed we build many custom rads and can build anything you would need. And guarantee it to cool your vehicle.

Re: Cooling

Thank you for the reply. Regarding the new coolant, an increasingly common issue for those of us who go to the drags and now some other venues, is the ban on "anti-freeze" that many tracks are enforcing. This is usually targeted at at ethylene glycol formulations as they are very difficult to clean up.

Any experience or advice with your new product either from a track acceptance point of view or in the alternative any harm from drain, save, re-fill cycles with straight water in between?

To HEMI's question above which kind of water is best?

Re: Cooling

Our coolant is a new generation propolyene glycol, but as far as at the track im pretty sure all coolant is banned. And if you drain, save, and re-fill there is no problem at all as long as distilled water is used.

Re: Cooling

Any cooling issues or questions?

Here's an odd one:

If you could design any heat exchanger setup for a turbo car from scratch, would you go with an intercooler mounted in front of a conventional radiator, or a deeper radiator and intercooler core mounted side by side, and why?

I've seen the side by side arrangement used on some turbo cars like K-cars, as well as tractors (a very demanding cooling application, since you're running wide open throttle, full boost - at 6 mph). But it seems pretty rare, so I was wondering what the pros and cons of the two approaches are.

Re: Cooling

To maximize core surface area and if possible use puller fans that cover as much core are as possible. Location of intercooler to cover least amount of radiator core area so your no preheating occurs. Remember thickness restricts airflow.

Re: Cooling

Does BeCool make water/air intercoolers or the related heat exchangers (think Terminator Mustangs or Lightening pick ups?

[88 Vert Stang Dan]

Re: Cooling

Not for a regular production item, we custom build many intercoolers etc.

Re: Cooling

One more fan question. I'm using an OEM Ford/Lincoln Mark VIII fan that reportedly pulls 4500 CFM. It certainly works at least so far. It is an integral shroud type with a large single central fan with large larger rectangular shroud extending from it in to the corners of the radiator core. I had thought that to keep good flow through the entire surface of the radiator it was important to keep the flat portions of the shroud some distance form the core. In this case its about 1.5". Given your answer regarding electric's fans is that right? Should I cut down the fan shroud?

I know BCT said a 1/2 inch, but my friend from Ron Davis told me 1 inch, which is the spacing the fan shrouds he made me have.

I would think that 1 1/2" would be ok to, main thing is to make sure the shroud is "sealed" to the radiator. I used some weather stripping from Home Depot to seal the out side edges of the shroud to the radiator.

Also if your running dual fans you'll want to put a divider in the middle of the shroud between the fans so they pull more evenly across the radiator.

Re: Cooling

Are dual pass radiators significantly better than single pass assuming both are cross flow, and have 1" aluminum cores and the same size cores? This goes back to the Silver State question.
