How much HP can a 38mm wastegate handle?
Drlee50. If it’s located properly, 38mm will flow enough to keep you in the 500-560hp range with low or high boost.
What is a wastegate dump pipe?
The dump tube is usually just a pipe that is flanged to go on the wastegate and then it leads down so that it isn’t dumping the exhaust into the engine bay. You can mount an external wastegate on the O2 housing, or on some turbos it can be mounted on the turbine housing.
What is an open dump wastegate?
Open wastegate is more efficient and is the best method to hold boost at a consistent level. The trade off there is, its loud. Think of it as a huge exhaust leak when you’re in boost. A Recirc’d dump fuctions the same way as an open gate, but instead places the exhaust gasses in the downpipe.
Are bigger Wastegates louder?
What is a Wastegate pipe? If you have a large turbo and only running 10psi of boost then the waste-gate noise level will be a lot louder than if you are running 30psi of boost because the waste-gate has to vent more volume (exhaust gas) to keep the engine running at 10psi.
What does a turbo dump pipe do?
A dump-pipe is as stated; a pipe connecting a divorced wastegate either back into the exhaust (post turbo) or out by itself. It is to bleed exhaust pressure around the turbo.
What is open dump turbo?
open dumps…. they take the exhaust gases that are by-passing the turbo via the wastegates and dumping them straight out to the atmosphere. Generally turbo setups reroute these gasses back into the exhaust system. By dumping them rather than rerouting back into the exhaust, you are relieving backpressure.
What is an open dump downpipe?
This downpipe features a vent to atmosphere wastegate dump for an intimating sound at wide open throttle. This downpipe has been engineered to be one of the highest flowing downpipes on the market with a CNC tapered flange that matches the turbine outlet perfectly. Features: Split Wastegate and Exhaust Design.
Is a bigger wastegate better?
An engine that produces a lot of exhaust gas but runs low boost levels will require lots of exhaust to be diverted away by the wastegate, requiring a bigger wastegate. Higher boost levels will need less exhaust to be diverted away from the turbine, so smaller wastegate.
Which wastegate is the best?
For a turbocharged car that sees primarily street use, most people think the smaller 38mm wastegate would work best, and although it is not a bad choice, ultimately the 44mm would work better for most street applications. A street car will not be running the turbocharger at its peak efficiency all the time.
