Boost Controller

[fEkuaR]

Hey guys,

Just got my hands of a slighyly modified gtst r33 as far as i know the only mods are slightly bigger turbo, turbo back trust exhaust, slightly bigger intercooler so anyway ... today i connected a boost guage to check what its actually doing. It reads that it is running 7 psi till about 4500rpm then it hits 9psi. So i went and bought a manaul boost controller just a little t piece bastard and fitted it in.. I set it a turn and went for a drive i hoped that this would make it hold a consistent boost pressure i was on 9psi untill about 4500rpm again this time the bastard jumped to 16psi so i backed off went home and set the controller to as low as it goes so its running standard pressure again. Anyone know why its doing this?

Regards,

Dan

Have you bypassed the factory boost control? It pumps up the boost like you described (7psi then 9psi) I dont know if it would do the what you said to your manual boost controller but it sounds similar.

it sounds like you've plumbed the dual stage incorrectly and when the stock solenoid opens your controller interfers and the actuator doesn't see pressure properly so it basically runs unlimited boost, ie: you will cause damage

thats a possibility i had a talk to a guy who said that with the r33's you needed to take out the standard boost controller all together to run a manual boost controller but he said thats a bad idea? .. i tend to believe him as he has a 550rwhp gtst so he does know his shit

Manuals boost controlers arnt that bad if you dont and a grand to get a good ebc

just get a proper boost gauge and dont run more than 10psi with a standard ecu

You don't need a grand to get a good EBC.

The cheapest JDM one is only $450-$500 (GReddy Profec B-Spec 2) and you can find some used ones on sale here on SAU for even less than that.

Fided tho and its pritty close if you do all the things like gap plugs and gauge and dyno as well mine was 915 but better to bank on it being 1000 and it being 700 than 700 to 1000
