What is boost spike WRX?
Boost spike is when the boost level quickly jumps up then goes back down to where its suppose to be. If you upgrade a wrx turbo without a boost controller, watch out for some crazy boost spike…
How do you know if you have Boost creep?
If your car is suffering from Boost Creep, what you will see is at some rpm after your boost begins to taper as normal, your boost pressure will begin to build again, and if it does, it most likely won’t stop until you let off the accelerator. It will also most likely build well beyond your target boost.
What is boost creep?
“Boost creep is a condition of rising boost levels past what the predetermined level has been set at. Boost creep is caused by a fully opened Wastegate(s) not being able to flow enough exhaust to bypass the housing via the Wastegate(s) itself.
How do I get rid of boost creep?
Boost Creep is not a condition that can be corrected solely by making tuning changes as it is a mechanical limitation. The two easiest ways to address boost creep are to either port the wastegate housing of the turbocharger in order to allow it to flow more air or to switch to an external wastegate style uppipe.
Does Catless downpipe cause boost creep?
Catless cars cause boost creep which takes away my ability to control boost at high rpm. So on a stock car if you zero out the wastegate duty cycle it will run 8 psi flat all the way to redline.
How do you solve boost creep?
What can cause boost creep?
Boost creep is caused from the lack of back pressure and the physical wastegate hole being too small to bypass all the exhaust gas. Since the exhaust can’t fit through the wastegate hole, it is forced through the turbine wheel which causes the boost to uncontrollably rise.
How much HP does a pound of boost add?
Boost and Horsepower The general rule of thumb is that, not accounting for temperature-induced power losses, a turbo will increase horsepower by about 7 percent per pound of boost over a naturally aspirated configuration, and a supercharger will increase it by 5 or 6 percent per pound of boost.
