Heat lances for Asphalt Crack Cleaning are designed to blow hot air into cracks to remove debris and dry cracks in asphalt pavement. Hot Air Lances are ideal for cleaning and drying cracks in asphalt pavement, providing the optimal condition for achieving maximum adhesion when applying hot or cold applied crack fillers and sealants. Hot Air Crack Cleaning is the best method available for crack preparation when crack filling or crack sealing cracks in asphalt pavement.
Turba crack
Turbine housings can crack from an improper tune which causes high EGT (exhaust temperatures). Another reason why they crack is due to improper cool down of the turbocharger. It is important to let the automobile idle for a few minutes to let the oil recirculate through the turbo charger to remove the heat from the turbo charger. This cool down period is even more important in the winter time. During this idle time exhaust system will also release heat. Turbine housings cracking is not covered by OEM manufactures due to falling under the category of miss use of the turbocharger. This is also something that is out of our control.
Most manufactures use a nickel additive in the turbine housings, the help prevent cracking of the turbine housing. This significantly reduces the chance of the turbine housing cracking. However Often the turbine housing will still crack on sharp edges in the turbine housing.
Some companies have also used pure stainless steel turbine housings, which also reduces the possibility of the turbine housing cracking. However, sharp edges of the turbine housing still tend to crack. A way to try and prevent cracking is to use a porting tool and sand the sharp edges of the turbine housing smooth, which I do to the best of my ability. However I have no control over improper cool down of the turbocharger.
Subaru of America issue a recall for certain 2015-2016 WRX and 2015-2016 Forester XT models. Subaru says the turbocharger air intake duct on the 2.0-liter engines may crack and possibly result in an engine stall increasing the risk of a crash. 18,200 potential vehicles are affected by the recall for WRX and Forester XT turbocharged models sold in the U.S. The recall will likely spread to Canada, Australia and European models.
If there are any leaks, cracks or poor seals between the compressor and the engine, the turbo will have to work much harder than it should have to increase this pressure. This will reduce the efficiency and boost delivered by the turbo.
I you are feeling particularly ambitious; you can also check the exhaust side of the turbo. First, remove the exhaust pipe all the way to the turbo, so you can see the turbine wheel. This should look clean, with no carbon build up, scale or oil along the surface, and the blades should be free from cracks, wear and damage.
Extreme heat can kill anything, right? Well, the same goes for turbochargers. Prolonged exposure to 2,000 degrees Fahrenheit will eventually take its toll on the turbine (exhaust) side of the turbo. Common failure points due to heat are: stress cracks in the turbine inlet flange, eroded edges of the turbine inlet volutes (pictured below) and deformation of the tips of the turbine wheel blades.
This is our third revision of our simple bolt on larger upgraded turbo for your 1.4L turbo Cruze/Sonic. After extensive R&D testing with the stock frame we discovered that the outlet going from the head/manifold to the exhaust side of the turbo was THE restriction. We have increased the inside diameter in that "penny choke" area resulting in a 50% larger AR, going from .40 to .60. What this means to you is actually faster spool over the V2, which is a-typical with an increase in AR, however the restriction is so bad on the stock frame that this increase means an easier and more efficient path to the turbine wheel. You will also see significant power increases without having to lean on the turbo as much, expect around 30-50whp than a stock turbo at the same boost level. Past the new cast exhaust housing the compressor wheel (inducer/exducer) is 18 percent, and the turbine wheel is 12 percent larger than stock (these remain unchanged from the V2), and finally the wastegate diaphragm is 2psi higher than stock. The dyno graph below represents two very similar builds, one on our old V2 and another on our V3; you'll see that even at the same boost level the V3 makes more peak power and torque, as well as a considerable amount of power under the curve. While the V3 is a great stock frame replacement, if you're looking to make power on your 1.4 we highly recommend our Z04 turbo kit, found here. The factory turbocharger is known for the exhaust housing cracking or the wastegate not being preloaded correctly causing slow spool. When you only have a 1.4 liter engine, you know how important spool is, our goal was to make an upgraded turbo that doesn't spool much, if any, slower than stock but still makes more power.
Your stock drain line is likely frail or may crack during removal of the stock turbo, we sell an upgraded replacement here.Many customers like to do the upgraded bypass valve spring mod at the same time. The V3 has a different tone and pitch bypass sound than the stock turbo, the upgraded spring changes that sound to something more similar to stock. Upgraded spring can be found here. This turbo has a different sized bypass valve assembly than the stock turbo. Aftermarket bypass valves for the stock turbo WILL NOT fit the V3. Continuing on from the great success of our MSD buyback program, Zoom wanted to put another offer out there! Starting now if you own one of our V1 or V2 big wheel turbos for the 1.4, and then purchase our V3 turbo you are eligible for our turbo buy back program. We know those with V1 and V2 turbos are leaving power on the table, and we want to offer a more affordable way to get into a V3. The program works like this: purchase a new V3 big wheel turbo using the same account/email address that you did for your V1/V2. Once you've received your V3 and installed it, return you original V1 or V2 turbo. Ship it back to ZZP after you've received an RMA from customer service and you will receive 100% of your original V1/V2 purchase price in ZZP store credit. This is why you continue to stick with ZZP, no one supports their customers like this. Email customerservice@zzperformance.com if you'd like to start the upgrade/buy-back process. Update 3.17.2020 - V3 version released. 2ff7e9595c
