boost controller

i was wondering if a boost controller was worth the money for the stock turbo. also how much boost should be run on the stock turbo.

yes it is worth it on the stock turbo! but what other mods do you have? its not going to be super effective without proper mods and tune! here is the typical mod path for a evo 8

-Boost gauge, first thing!
-Basic matience ie. Plugs wires and other general stuff.
-turboback exhaust
-intake
-BOV if you have the OEM plastic one
-Fuel pump
-tune

Optional:
-Intercooler pipes
-Front mount Intercooler
-Cams
-Retune if you get these parts....

You should be able to run around 22-24psi with those mods and no issues.

I have all this on my 03 stock turbo plus alky injection and I have about 400awhp and no lag time

you dont have to but your ecu can only compensate for so much extra air being forced in the motor. Honestly I think the only reason someone would run a MBC at the stock setting is to stop boost taper. To get the most out of your car you should def get a tune, even if its for the stock setup, this will lean it out a bit and give you better AFR. TBE, fuel pump and a tune should give you a decent bump in power.

just to piggy back on whats already been said..... you can get a good MBC off ebay for like 20 bucks... NXS makes on for 19.99 i believe.. a friend of mine made 500+ on his DSM pushing over 30psi on it..

i wouldnt trust my turbo and motor to a $20 boost controller. if the spring fails or there is a flaw it could be a a major overboost issue.

that could happen with any MBC.. Back when Slow Boy Racing first started Mike Hummel was manufacturing his own MBC's and selling them for dirt cheap.. i thought the same thing...he told me... alot of them utlize the same parts that forge.. turbonetics any name brand MBC... the design may be different... but the application is still the same.. more often then not your buying the brand name..

^^ i disagree i have been thru about 8-10 different boost controllers all with pros and cons. look around and search some do work better then others. i'm not saying buy the most exspensive one, just do the reasearch and see which ones work the best and are easiest to adjust. some still taper real bad and some spike to high. i will be switching to ecu controlled boost coming up because for the evos mbc's are a thing of the past now. great bang for the buck, but i have seen excellent results on numerous evos.

A Hallman is a pretty reliable MBC. But you would get better boost control and faster spooling of the turbo with ECU controlled boost.

A boost controller is a device to control the boost level produced in the intake manifold of a turbocharged or supercharged engine by affecting the air pressure delivered to the pneumatic and mechanical wastegate actuator. A boost controller can be a simple manual control which can be easily fabricated, or it may be included as part of the engine management computer in a factory turbocharged car, or an aftermarket electronic boost controller.
