Legitimate Fix For Heat Soak

It's no secret that heat soak is a problem for our cars and is, what I believe, the biggest thing holding these cars back from being all they can be. It's also so secret that the real problem is the intercooler. Not so much the heat exchanger, a reservoir helps by increasing capacity, and chillers I'm sure work, but many including myself, don't want to mess with chillers or refrigerant. I'm just wondering, what way can heat soak be combated so that it doesn't heat soak much more rapidly then the GT500, or ZR1. Is there a way to upgrade the intercoolers? Is the only way around this to swap the blower?

honeslty why would you even think about that with products like the chiller on the market or just he fact that unless you are doing sustained hight speed work just an upgraded HX will take car of it.

I think your buying into the hype too much.


now on the flip side if you want to raise the boost to 15spi and run lap after lap then yes I would would run a different blower.

even the GT500 guys that do a ton of roadcoarse work swap the 2.3L eatons.


for 99% of poeple $800 in mods will fix the heat soak issue for normal driving habbits. I mean you can spend 6k on a new blower if you want but that is not how I would address it on this car.

I've read a lot of posts about how the ZL1 is more prone to heat soak than other supercharged cars. One of the posts I read directly compared it to the GT500 and they stated that the ZL1 heat soaked much quicker then the GT500 and the GT500 would leave the ZL1 like the ZL1 was "tied to a rock" due to the heat soak on the ZL1. For racing on a road course, would a bigger hx be enough? From what I was reading, it won't help enough and the biggest problem is the intercooler.

answer for this is active chiller "superchiller" . I, personally met with the guy who designs these for our cars. He impressed me as very honest, sincere, and intelligent.
He had a demo version, that he showed me, that was made from all high quality materials, it appeared to be very well thought out and professionally made. Mine is due sometime the end of the month. The designer (David) told me he is dealing with a full plate of personal issues right now, and that is why I will need to wait 2 weeks for him to put the kit together. (which is understandable). I was impressed that although I waived a few hundred dollars in front of him as a down payment, he told me, he didn't want anything from me upfront. I heard a different story from someone else, but I believe he treated me this way because I am dealing with a performance shop that is going to install the kit for me. So I am going to pay the shop and the shop will pay him. If this kit does work the way it is designed too, I am going to have a huge advantage when summer time gets here in FLorida. I look forward to posting the results soon. This is his website url.

It's a very ingenious and creative idea, but after doing some reading on guys that have done superchillers, I'd rather not molest the A/C lines of the car.

You will not hack your car into pieces with this kit, he showed me the fittings for it, it was all high quality aluminum connections and lines. I can tell you that David had a partner a few years ago that has tried to steal the design from him, and that this person's name is Tracy. This person lists the same product that David showed me when I met him, on this website http://www.revxtreme.com/rx-super-chiller This is exactly what David showed me. From what I hear from David, You DO NOT want to buy this kit from Tracey, apparently tracy can put a pic together but not a kit. He will take the kit and assemble it like crap from what I have heard. So this is what the kit looks like, again I would not trust this tracy person, but I will post this for Pictures sake.

Here's a thread I put together based on some research I did. I am setting my car up for road racing and cooling is one of the things I will be doing soon.

I had the "Superchiller" from Tracy Lewis @ RxPerformance on my old Camaro. The system cooled my intake temps to around ~65 degrees F, but my goodness the system had some serious issues and was the biggest pain in the a$$. It leaked freon! The fittings were pretty crappy, some were even cross threaded and loctite was used so it wouldn't come apart, I'll see if I can dig up some old pictures.

so has anyone done a dyno pull with this on consecutive pulls to really put a load on the engine? whats the power with it on and without it off like to see how much it makes with the a/c putting a load on the engine while its on.

I believe for what the superchiller will give back in consistent performance, will easily off-set any mild losses in Hp from using your a/c.

So what did you end up doing to combat the heat soak? Did you get the Lingenfelter pump? I can't believe the reservoirs actually melt when the fluid flows into it.

In my opinion, heatsoak as they generally define it...where the heat from the motor rises up and warms the intake charge to the point it pulls timing and you lose power is not really a problem. I have upgraded my cooling with a new exchanger in the grill and a new reservoir from the start. With those upgrades I would not worry about the heat from the engine soaking into the supercharger for drag racing. For road racing and I'm turning my supercharger at around 22,000 peak rpm, the supercharger is the hottest item on the car. It gets so hot it will boil coolant passing through the brick and if you can't re-condense it to liquid you will melt anything plastic in the system and and boil out all of the water. I know this from experience. The brick intercooler in the supercharger is a weak link....at least in the stock blower...it is pretty small, if you increase the rate the water is pumped through it you get the same effect as a larger brick.... The way IAT2 temp pulls timing in the stock car it is a self limiting problem. The car pulls timing and reduces available power until the heat is reduced. If you have so much power that it cannot pull enough timing it will just turn the engine off and you will have to wait 5-10 minutes to restart it. I have been there also.

A dyno run lasts about 5 seconds. Even if you do 20 consecutive pulls, this will not equal putting the car on a road racing course and keeping the tachometer between 4 and 6000 rpm for 30 straight minutes. I have many hours of road racing in my car and have been on the track with the ambient at 106 degrees. Now let me tell you something I figured out running laps when it is over 100 degrees, the car turns off the a/c compressor whenever you exceed 3/4 throttle. I know this because when it is a 100 degrees out and I have a helmet on my head and long sleeve clothing I keep the a/c on. The way I drive, the throttle position sensor will turn off the compressor for about 80% of the track so basicially if you plan on using the stock a/c compressor to cool the supercharger or anything else while road racing forget it. At least not unless you do some modifications.

When you hit the throttle it turns the a/c off so you don't lose any power to the a/c compressor.....but you don't get any cooling when you actually stand on the gas. The chiller really is a good system for heat sink... will keeps intake temps down at the drag strip when idling or when your car is off.... but at sustained speed it will not work.

anyone have an idea/guess of what the water temperature leaving the intercooler would be approximately and what it might be returning back to the intercooler with a stock Hx on say a 90 degree day?.

Won't work with the standard CAI though. Only the New Era Race CAI.

That's exactly the problem I want to address. How did you go about fixing the problem? What is the best way to fix this problem? Is a HX and reservoir enough? And the reservoir will melt in these conditions according to what you say, which even further complicates things.

Seems like the best way to go about this is to simply swap the blower. I just don't understand why the blower is so expensive. Usually a supercharger kit for a N/A car is about 5-6 grand, and that includes lines, piping, HX, everything. Why does a simple blower replacement cost just as much as an entire supercharger kit??

I wish I would have taken pics of the reservoir I threw away. Part of the problem was the way the coolant lines were routed but I don't think anyone thought about this stuff much until I really started pushing my car. If you route the line directly out of the supercharger (where it is possible to convert the coolant to steam) and then stuff it into the bottom of a plastic reservoir.... Once you get enough steam heat and pressure the reservoir puffs like a perfect balloon and then the filler neck melts in grooves to vent the steam..... I would recommend if you do any road racing, to put your reservoir after the heat exchanger in the grill where it will take cooler water instead of steam.....and then plumb it to the intake....and then if you decide to ice.... your ice water goes into the supercharger instead of the heat exchanger in the grill....as many standard systems do.
