I have had a lot of people inquire and ask about why there is such a difference with a Shelby dual fan heat exchanger versus heat exchangers with out fans.

The answer is in ambient and convective heat soak from the heat generated within the engine block.

When our cars are cold and we start them up and get going they are crisp and have tons of power because they are obviously cool. So what happens to many of us is we drive the car after it has gotten up to operating temperature and then we park the car. Whether you run in for a sandwich or whatever the car is sitting in a parking lot or your driveway after being warmed up and the operating temperature of the car is likely close to 180-200 plus degrees. When you let the car sit all of the heat from the block permeates the engine and subsequently the intercooler and the fluids within the intercooler and radiator causing those fluids to rise significantly. So an 30 minutes, an hour or two hours later you fire the car back up and it's completely heat soaked because nothing has been done to reduce ambient temperature because of the convective and ambient heat of the engine permeating and heat soaking the cooling mediums within the engine components.

When you utilize a Shelby dual fan heat exchanger the fans kick on and start to pull the heat from the heat exchanging and intercooling system immediately. Without fans you will have to drive the car for a good amount of time in order for the air to flow over the heat exchanger and cool the intercooler/heat exchanger fluid down to a point where timing is not pulled if you can get it to that point. Usually a long cruise on the highway can remedy the problem however stop and go traffic is brutal and difficult reduce the ambient temperature after a re-start.

The concept of the dual fans is that after the car has sat and gets heat soaked from sitting you immediately begin the process of removing the heat which gets you back into the power band much faster and gets the timing and spark advance retard point back to a point where it is under control and allows the ECU to provide you with maximum timing and spark advance.

In multiple data logs I have seen that the recover time of the intercooler fluid is much greater with the fans versus a non-fan heat exchanger. This is even faster when distilled water is utilized versus anti-freeze which is designe to retain heat, thus the reason why it is called 'Anti-Freeze', it holds heat.

A lot of people have said that I don't 'Race' my car. You don't have to 'race' your car to experience and utilize the benefits of a Shelby Dual Fan Heat Exchanger even if it is a daily driver.

Get the heat out as soon as possible and as quickly as possible.

Many drag racers use my heat exchanger with great success when they run back to back to back runs in something like True Street. For example, a member on Team Shelby, Kostas, actually improved his ET after each run at the NMRA event at Bradenton. His driving was good and his car wasn't pulling timing even as he went through the waiting time between rounds when you are not allowed to open your hood. And he doesn't have a trunk reservoir where you can access the trunk in a true street event. If he had no fans on the heat exchanger the idle temperatures would accelerate and his ET's would have been lower due to heat soak.

Please feel free to post your questions and I look forward to answering them.

Thanks

Great post Van.

Thanks for sharing.

Another reason to JetHot your exhaust headers ... if you have them.

Also, I always try to give my girl a cool down mile after a run. Then when I pull my girl into the garage, I prop the hood open.

I can testify that the Dual Fan Heat Exchanger and the larger radiator Van has developed; works. Van stands behind his products. I had the radiator and dual fan heat exchanger installed and it has made a marked improvement in my supercharger performance in this Texas heat.
I have had various mods done to my car this past year by different vendors and have had problems with all of them except Vans.
The best part about this story is when everyone else screwed up my car , I could call Van and he would get me out of trouble. He is +1 .

Just make sure you use a shop that knows what they're doing or know how to install it yourself. I had the heat exchanger and radiator installed at a speed shop that I'd used previously and thought was pretty good. They charged a lot for the heat exchanger install. They claimed that it was a bear of an installation and that they had to custom fab brackets. The heat exchanger came with no installation instructions, which probably didn't help things. They managed to mess the wiring up big time in the process.

After a very short time, the car wouldn't start and one fan was out. I ended up having to take it to a specialty electrical shop to fix all the wiring and replace the fan (with all the associated towing, hassles and costs).

I haven't had any problems since and don't have any beef with the product. My installation experience just turned out to be a major headache that hopefully others can avoid. I would recommend that installation instructions (including wiring diagrams) be included with the product.

FYI, it also draws a fair amount of electrical power. I ended up upgrading my alternator as well since I was running out of margin.

I have a SGT/SC with the Whipple 550 h.p. and i don't race the car. If i were to install just one improvement to the cooling then which would be the best choice, the radiator or the heat exchanger. If i went with the radiator would i need the tanks? Also how much does most people charge to install the radiator and or heat exchanger. Thanks.

Great post, and this makes perfect sense to me. I have a couple of questions though.

1. Does the heat exchanger conflict with any other items or accessories, for example, brake cooling duct installations?

2. How long should it take the shadetree mechanic to install?

3. What does the finish install look like, i.e., do the SHELBY letters show up at the lower grille area or where?

Thanks!

I just had SA install my Revan heat exchanger in Las Vegas. Prior to my car going to SA, I checked locally with a couple of speed shops and was quoted from $150 to $200 for the install. Since my car was going back to SA, I had the install done there. The install instructions are pretty straight forward, and a "shade tree mechanic" should not have any problems installing it.

The heat exchanger does interfere with the front brake ducts, if you have them installed, but from what I know, the ducts can be modified to make them work. ( I do not have the front brake ducts.)

The Revan exchanger is very well made and is paint-stamped "SHELBY" across the front which is visible through the lower grill opening.

I did not install the larger radiator or tanks on my car.

Hope this info helps.

I'll be taking mine to Vegas for the install, too. UPS delivered all the components (radiator, HE and tanks) to me a few days ago. Since I've got an automatic, I'll also go with a trans cooler. I've got the time to do it myself, but I don't have access to a lift and don't much feel like putting my arthritic knees and back through the contortions anymore...

There is a lot of infomation that can be obtained from these forums if people would just take the time to answer. Thanks for the answer. I believe i'll probably go with just the heat-exchanger as i am really just concerned with the s/c cooling. Thanks again.

This is all really good info. Extremely informative. I'm going to save this for later reference when I get my SC. I'm planning on going with the Kenne Bell 550HP

Does anyone know if this heat exchanger provides much benefit on an NA car? Also, if a supercharger is added later, will there be any conflict w/ the heat exchanger, or will any part or section of the heat exchanger then need to be modified or re-installed?

If you do not have a supercharger than there is no need for the heat exchanger for it is specifically designed for SC applications.

Thanks! I was wondering, because there is always so much discussion re: reduction of underhood temps freeing up the horsepower.

NA cars dont have heat exchangers, just a radiators

I did not install the larger radiator or tanks on my car.

...


Same here, stock radiator and tanks; Shelby heat exchanger being installed with Whipple H.O. supercharger.
Also adding the driving lights. All mods being done at TASCA. TASCA will not install the lower aluminum grille if having the driving lights so I opted for the heat exchanger for the cooling and the SHELBY logo to fill in the space in the lower front fascia.

I have had a lot of people inquire and ask about why there is such a difference with a Shelby dual fan heat exchanger versus heat exchangers with out fans.

The answer is in ambient and convective heat soak from the heat generated within the engine block.

When our cars are cold and we start them up and get going they are crisp and have tons of power because they are obviously cool. So what happens to many of us is we drive the car after it has gotten up to operating temperature and then we park the car. Whether you run in for a sandwich or whatever the car is sitting in a parking lot or your driveway after being warmed up and the operating temperature of the car is likely close to 180-200 plus degrees. When you let the car sit all of the heat from the block permeates the engine and subsequently the intercooler and the fluids within the intercooler and radiator causing those fluids to rise significantly. So an 30 minutes, an hour or two hours later you fire the car back up and it's completely heat soaked because nothing has been done to reduce ambient temperature because of the convective and ambient heat of the engine permeating and heat soaking the cooling mediums within the engine components.

When you utilize a Shelby dual fan heat exchanger the fans kick on and start to pull the heat from the heat exchanging and intercooling system immediately. Without fans you will have to drive the car for a good amount of time in order for the air to flow over the heat exchanger and cool the intercooler/heat exchanger fluid down to a point where timing is not pulled if you can get it to that point. Usually a long cruise on the highway can remedy the problem however stop and go traffic is brutal and difficult reduce the ambient temperature after a re-start.

The concept of the dual fans is that after the car has sat and gets heat soaked from sitting you immediately begin the process of removing the heat which gets you back into the power band much faster and gets the timing and spark advance retard point back to a point where it is under control and allows the ECU to provide you with maximum timing and spark advance.

In multiple data logs I have seen that the recover time of the intercooler fluid is much greater with the fans versus a non-fan heat exchanger. This is even faster when distilled water is utilized versus anti-freeze which is designe to retain heat, thus the reason why it is called 'Anti-Freeze', it holds heat.

A lot of people have said that I don't 'Race' my car. You don't have to 'race' your car to experience and utilize the benefits of a Shelby Dual Fan Heat Exchanger even if it is a daily driver.

Get the heat out as soon as possible and as quickly as possible.

Many drag racers use my heat exchanger with great success when they run back to back to back runs in something like True Street. For example, a member on Team Shelby, Kostas, actually improved his ET after each run at the NMRA event at Bradenton. His driving was good and his car wasn't pulling timing even as he went through the waiting time between rounds when you are not allowed to open your hood. And he doesn't have a trunk reservoir where you can access the trunk in a true street event. If he had no fans on the heat exchanger the idle temperatures would accelerate and his ET's would have been lower due to heat soak.

Please feel free to post your questions and I look forward to answering them.

Thanks

How long would it take a shade tree mech to install this system?
I have a paxton and front brake ducts, will any of this have to be modified?
Does it come with all brackets I need?
Does it come with instructions for wiring and installation?

Thanks

I did it in a day but I had Van from Revan Racing in my garage helping since it was basically used as the prototype for the Shelby SGT/SC cooling kit. Count on a full day for the radiator, the heat exchanger is a couple of hours with wiring being the longest part.

The radiator is not an easy install with the Paxton but I consider the cooling upgrades the the second best mod I've done to the car (SC being 1st) because of the consistent performance improvements year round, big difference in power after the motor gets heat soaked (20-30 minutes).

I removed the lower radiator support bracket and dropped the stock radiator out of the bottom (no fun). Getting the wider radiator to fit with the Paxton requires a little fabrication but was totally worth the effort it in my opinion.

Power and heat go hand in hand so anything you can do to efficiently bleed off excess heat from your motor is money well spent, otherwise you are losing a lot of power that you already paid for in a supercharged car.
