MichaelP Posted June 23, 2011 Report Share Posted June 23, 2011 Hi - Im getting conflicting advice. Some racing motorsports shops saying a bigger heat exhanger will not help for road racing since it (heat exchanger) will never really be able to keep up with cooling demands... other shops saying it will help.. Is there anyone running a S/C on their 'stang on road courses during the summer that can say Yeah or Nah on this ?!? I know Revan racing likes them for their cars.. Thanks, Mike Link to comment Share on other sites More sharing options...
clark17357 Posted June 23, 2011 Report Share Posted June 23, 2011 My experience has been that the Revan Racing/Shelby cooling package (the whole set up which includes the big radiator) has been very helpful in my road racing adventures. I had my car supercharged in 2008 and ran it on the track for two summers before getting the Revan Racing/Shelby cooling package. I tend to prefer shorter tracks with very little in the way of straightaways so I am building serious heat all the time. Bottom line, I have seen a significant difference. I was used to heat soak robbing me of power in the later portion of a track session. Now, I do not notice any heat soak issues under any conditions. The highest ambient temperature I have run at is 95 degrees. I will be interested in the experiences of others. Jim Link to comment Share on other sites More sharing options...
03 DSG Snake Posted June 23, 2011 Report Share Posted June 23, 2011 I would say the more cooling you have for the road course the better. Right now I have the Reische Thermostat and 'older' AFCO heat exchanger. ECTs are ok, but IAT2s really heat up, especially after sitting in the pits after a session. I am looking to swap to the Revan H/E. I think the fans alone will help me with my issues. After running a session, and coming back into the pits, even letting the car run for a few minutes will leave everything heat soaked until the next session. Fans would be huge in cooling it back down before going back out again. Link to comment Share on other sites More sharing options...
07SGT4578 Posted June 23, 2011 Report Share Posted June 23, 2011 +1 Jim. I can attest to his statement. I have driven his car on the track both before and after the cooling kit was installed. There WAS a significant diference in when heat soak started to rob power. Link to comment Share on other sites More sharing options...
OsirisGT500 Posted June 24, 2011 Report Share Posted June 24, 2011 For me the radiator was key. That was the cure. I do have the LFP HE as well. Link to comment Share on other sites More sharing options...

DaFreak Posted June 24, 2011 Report Share Posted June 24, 2011 I ran the C & R radiator and AFCO Dual Fan HE with AMSOIL Coolant booster for a full on track day (5@20 min & 3@10 min sessions) last month at PIR and had 0 issues with heat soak. I never did a track day running the stock Rad and HE so I've got nothing for ya there. Personally, I'd be more worried about your brake cooling (assuming you get a larger HE/Rad).

Thanks, Mike Mike It's not a 'bigger' heat exchanger that makes the difference. It's the efficiency of the core. I developed the heat exchanger and radiator initially for my own personal use in my GT500 running the road courses of Florida in the Summer. Anbody that says a heat exchanger can't keep up with the demands of running on a road course well, they just have not seen my product. I've got both in stock. If you have any questions or want to discuss the products give me a call and I'll give you a detailed explanation and describe my own personal experiences.

clark17357 Posted June 24, 2011 Report Share Posted June 24, 2011 Personally, I'd be more worried about your brake cooling (assuming you get a larger HE/Rad). DaFreak is spot on with this point. Having an SGT, it was not "born" with a supercharger. But even NA, I toasted the stock brakes (which are not the match for your GT500 guys' Brembo front brakes) at the track event at the first Shelby Birthday Bash in January 2008. In 2008, Shelby and Baer had not yet gotten their heads and rear ends wired together on a big brake kit that had big brakes front and back so I went with AP Racing and have never been sorry. The GT500 is a heavier car than the SGT so the brake issue is even more important. My philosophy is that you are well advised to spend as much for brakes as you do for a power adder if you want to have things work well on the track.

Van van@revanracing.com 561-445-7702 Hey Van and Everyone- Thanks for all these replies. I was 100% set to do the mods (with Van's components) and I was a little shocked when my local racing shop said "well, we can install but it will not make a difference and we will just be taking your money..".... hence the post on this forum.. Im going down to the performance shop this weekend to take a look around.. they are a huge outfit in my area and do A LOT of SCCA racing..

Thanks, Mike Whoever said it doesn't help on roadcoursing your Shelby doesn't know what hes talking about -- it will be a night-and-day difference from the stock HE and radiator as far as losing power 15-20minutes into each session on the track (heat soak)...with the upgraded HE and Rad, you will NOT experience this and your car will be at full power the whole session...

Hess Motorsports Posted June 28, 2011 Report Share Posted June 28, 2011 Here is my 2 cents after road racing boosted cars since 2003. A more efficient H/E design helps all the time. Especially at speeds when the airflow is at its highest. Shrouding and ducting can adda lot to the overall efficiency as well. A larger core doesn't due much as does a larger reservior. All that does it make it take a minute or two longer to heat up. Fans are great during slow speed (25mph or less) and when in the pits to help pull the heat out of the core. But any real racer can tell you that fans do NOT DO ANYTHING above 25mph which is why all NASCAR, ALMS, and World Challenge cars don't even run them on any of the coolers or radiator. The RR core deisgn works well and the fans help during pit stops and at street lights for the non-racer guys. Link to comment Share on other sites More sharing options...
MichaelP Posted June 28, 2011 Author Report Share Posted June 28, 2011 Ok.. Here is a question. I have an AIMS unit installed with a sensor for engine temp...usually runs around 192 maybe a little over.....when Im running around the course. Is there any sensor to be installed that will measure S/C heat soak or not? How do you really measure this BEFORE and AFTER the mods are done? Is there any way to measure? Just curious. All my other mods to car have worked really well and this was kinda the "last" item on my list. HA! Is there ever a "last" mod?!?!? M. Link to comment Share on other sites More sharing options...

That's all you need to watch 'heat soak' really. Link to comment Share on other sites More sharing options...
tony356 Posted June 28, 2011 Report Share Posted June 28, 2011 I have Van's HE on both my 500 and my GT350. I would buy both again. I will tell you this about the 350. She will run with anything on street tires for about 40 minute or so before the car starts to pull back timing and therefore pull back the power. If I could only keep off the boost a bit..........

I will look at data.. My AIM's unit will not have IAT2 listed as that but I can probably figure it out if I know what the temperature is roughly.. since it is pulling all the data from OBD. Any idea what normal is in Farenheit for the downstream air temp? M. Link to comment Share on other sites More sharing options...

EXCUSE ME!??! I don't know where you got your information from but I have "a little" first hand experience with NASCAR race cars from local dirt tracks (Street Stock, Late Model and IMCA Grand-Am) on up through the Regional Featherlite Southwest Tour on to the National Craftsman Trucks (Camping World) Series, Busch Grand National (Nationwide) Series and Winston (Nextel/Sprint) Cup Series with a couple of different teams and some fairly well known drivers. And on the way to WC I got a little experience with SCCA, USAC ASA and ARCA teams. I hate to be the bearer of bad news but on ALL of the full bodied Stock Cars I've ever helped build or worked on, we had more fans on the cars than Jr. had in the stands...INCLUDING the radiator cooling fan. Perhaps you saw tonights Daytona race where one team reported that their radiator fan was melting and causing a overheating problem on their car? And then Larry Mac did a short presentation on the radiator cooling fan showing it on their cut-away car and describing it as a "plastic or carbon fiber fan"? I can't speak for ALMS or World Challange but I know people in the Petite LeMans and could certainly find out but i can say with 100% certainty that NASCAR indeed DOES use fans on their coolers AND radiators (And C&R Radiators too!). Sorry dude but your information is just not accurate at all. Been there done that and seen it with my two own eyes, Phill Pollard Link to comment Share on other sites More sharing options...
