Do I need a wastegate on my Diesel?
The wastegated turbo is great because it’s got a housing on the exhaust side that will spool that turbo up quick, but at the high rpm, when it’s spinning fast, it’s just too much for the compressor wheel. So, we need a wastegate to control the speed of the turbocharger.
Does the 6.7 Cummins have a wastegate?
The 6.7 Cummins turbo system does not have a wastegate and it has a 60mm compressor wheel. The exhaust flow varies over the turbine wheel, which allows the system to respond more quickly at lower speeds.
Do I need a wastegate?
If you’re fitting an aftermarket turbo, you may need to invest in an external wastegate to effectively control the additional boost and power (and many larger aftermarket turbochargers aren’t fitted with internal wastegates anyway).
What happens if you block a wastegate?
The wastegate OPENs to let excess exhaust flow bypass the turbo, it is held CLOSED and pressure from the boost side controls it. Blocking the flow is essentially all a boost T does, by turning the T boost up it restricts the pressure into the wastegate control ‘tricking’ into providing more boost.
How much boost can a stock 6.7 Cummins handle?
When pushed to its absolute limit, the OEM fuel system on the 6.7L Cummins (lift pump, CP3, injectors) can support as much as 530rwhp and roughly 550rwhp with a turbo upgrade.
Can I run a turbo without wastegate?
You don’t need an external wastegate. While, in theory, you could run a turbo system without a wastegate by carefully choosing a turbo that will only reach its maximum turbine speed and desired boost pressure at the engine’s max RPM, it’s not practical in the real world.
What happens when you run a turbo without wastegate?
With no wastegate the turbine is even more of a restriction at higher rpms and boost levels so 30psi with a welded wastegate could be no better than 25psi in a normal setup.
Can you block off a wastegate?
Premium Member. As long as you don’t exceed 35 psi boost it won’t hurt a thing blocking off the wastegate. Of course this means you must have a boost gauge.

How much horsepower can a stock 6.7 Cummins transmission handle?
Does a wastegate add horsepower?
False! A wastegate is possibly the only component in your whole engine package that can be made smaller as you increase your boost/horsepower output – in certain circumstances. A wastegate drives exhaust gasses away from the turbocharger to regulate turbine speeds and boost pressure.
What’s the purpose of a wastegate on a turbo?
The wastegate is employed to control boost pressure via bypassing a controlled amount of exhaust gas from interacting with the turbine wheel. It consists of nothing more than a disk that closes against a passageway that redirects a portion of the exhaust flow.
What is a boost fooler Cummins?
The Boost Fooler will allow you to increase turbo boost to compensate for the added fueling modifications you have made. Enabling your turbo to produce more boost will increase overall horsepower and torque and lower your exhaust temperatures.
