whats the best boost control

[Let Me Drive]

hay guys just like the title what is the best boost control for the R33 gts-t running aroung 240 kw at the wheels im on a fixed setting i want to be able to change it so i dont thave to run such high boost all the time

Prize: any

type : any

but need to know where to get from and who to talk to

thanks any info would be realy good

why do you want to run two types of boost? if i had a two setting boost controller i would just leave it in high mode all the time. ok so are u running 240kw at the weels or u want to ?

bleed valve is cheap and nasty way of doing it, as it bleeds regardless of pressure level and limits itself to a max setting that you choose

electronic doesnt bleed until it gets to its set level (user settable) and then starts to bleed pressure off. the electronic is of course better and more expensive and probably safer too

there have been cases (numerous) where the bleed valvle option goes over its set level ie if you set it to 8psi on a cold day it could goto as far as 12psi, now thats ok but if you so close to the limit if your turbine at say 14psi and its a cool day and you get whats called boost spike then it could be risky for engine (detonate / knocking) or for the turbo (too much pressure)

i believe the hks evc is the preferred among the 250rwkw ish gtst members

i would if it was me and i had 240rwkw i would look at the power fc and boost controller kit for it. the power fc as its full engine management and the boost controller kit is an addon for the power fc and uses the same setup as the apexi avcr its the same electronic valve

post your current setup and power and what you want and someone will suggest something

HKS EVC 3 or 4 are very good especially with external gates.

The right spring rate in the wastegate actuator, nothing else comes close.

I use the accelerator pedal for controlling boost, if i don't want to go so fast I don't push the pedal down so far. :jk: I really find it a pain when I drive cars that have adj boost settings on controllers. While I am fiddling around turning the boost up, the race is lost.

Ahh see, you're meant to estimate your opponents power and change the boost setup before you race! The less things the driver has to fiddle with or monitor, the more they can concentrate on actually driving the car.

Oh and for boost controllers, Blitz SBC-Id3 = the best

ahh yes i use a 1 bar wastegate spring for my low boost setting, but you gotta use some sort of ebc when you switch to a higher boost setting, eg i use 21 psi on high

Are you guys using internal wastegates with 1 bar springs. If so where did you get them from?

Thanks

At the moment im using; Profec A Greddy EBC, cost me $300 2nd hand, and so far i have no problems holes boost lvl very good, and also i can change to wat lvl i want in a second

ohh yeah and it uses a stepper motor which i heard r best (hks EVC also uses stepper motor)

NO 45mm external gate

...so if you wanted to run 11-12 psi with the stock turbo (and wastegate) for RB25, can you just change the spring - or do you need a whole wastegate replacement (like an rb20 one, for example) ?
