Legitimate Fix For Heat Soak

[Blown355]

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

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.

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.

That's how I thought it was supposed to be set up. Hot fluid from the supercharger flows to the HX, get's cooled, flows to the reservoir, then from the reservoir back to the supercharger.

I think a good pump, reservoir and heat exchanger will hold everything you can throw at it until about 675 whp which is quite a lot on the stock blower. Power and heat go hand in hand. If you want to go above 675 whp and push it non-stop road racing then at this point I'm going to say you need a bigger blower. And I feel like an idiot because 6 months after I bought my LS9 set-up, a new blower comes out that blows away every thing else in terms of cooling efficiency and airflow design.... the new Heartbeat LSA is no joke. It looks like it has about 4x's the intercooler capacity of the LSA.

Here is my reservoir, it holds over 3 gallons in the trunk and sits right behind the battery.

I want to hear more about this new Heartbeat blower. I'm anxiously waiting more results from people that are utilizing it. If it does really well at fighting off heat soak and can pound out 14 pounds of boost without even remotely breaking a sweat, It would be worth it to me. Think about it this way, with the deals on ZL1's right now, you can get a brand new ZL1, upgrade the blower to the heartbeat unit, and STILL spend thousands less than the GT500. You'd still have money left over for intake, long tubes, tune etc and even then, still not be in for as much as the Shelby. Not because the Shelby is so enormously expensive, it just has a famous dead guys name on it. Dealers aren't going much below MSRP AT ALL, which is already more then the ZL1.

It is brand new so not very many out there yet. But it sure looks to me like you could swap that thing on a ZL1 with a little more pulley and spank the mustangs all day long.

I posted this before in the superchiller thread here: http://www.camaro5.com/forums/showth...=196968&page=5

why not use an electric A/C compressor so it can run at all times like the toyota prius uses

I had one of Dave's 1st prototype SuperChiller from Tracy@RX on my 10 SS & had no issues with it cause it is the original one that no AC line cutting needed, Boost was 11psi & drops to 6psi while tunning it on the Dyno & realiesed it was due to heat soak so we added the SuperChiller & never had any issue with heat soak .
On my 12 ZL1 we added the SuperChiller from Tracy@RX & had LMR do the installation, it worked fine at 1st but started giving headach leaking & had to go through 3 AC compressurs due to that & now i am getting the Original one from Dave soon & i am sure that it will work flowlessly like the 1st one.

Agree with Jessrayo - if superchiller isnt a route you want to pursue, the limiting factor is the intercooler within the supercharger. Much smaller than LS9 (twin brick) or GT500. The new heartbeat looks like it could be a good solution.

[Emvici]

can the intercooler be swapped out for the heartbeat one? or does the whole Supercharger need to be replaced?.

You have to do the whole supercharger.

how come noone has come up with another lid and brick design for the ZL1? Is the market just not big enough or is it just cheaper to replace the whole blower rather than the bottleneck of the TV1900?

Clearance issues perhaps???
