Controlling boost for better traction, and other means of improving grip Options

[CilverSeliST205]

For a while i was considering buying myself a new toy, Turbosmart E-Boost 2, an EBC with a variety of features, one of them being the capability to map boost against time, rpm or GEAR. Now, I have noticed that breaking the traction on street tires is likely to occur not only on a hard launch from a dead stop, but also at WOT in 1st and 2nd gear short time after going over 10psi. Since this unit can control boost depending on gear i guess we could use it to stay within limits of traction in those gears! yes? no? suggestions? comments?

Since im still on internal WG and my actuator is on 13-14 psi, the EBC itself wouldn't help... Is there a way to lower WG actuaction pressure?? That is without welding the flapper shut and going external.

What turbo are you running? The stock ST185 wastegate is set around 7psi and the ST205 wastegate is around 9-10psi... The extra boost then comes from the TVSV bleeding some boost from the wastegate actuator.

its from '95 jdm sw20
i know i know my screename is misleading

its all about the tires. running less boost might give you more grip, but will also make less power. the best thing to do is to do is to get some slicks when you go to the track.

You can't just drive around in slicks all the time

as far as gear based boost control, all your really need is any ebc. the greddy typ-s i have has low and high boost settings. you can change the low boost to whatever you want in 1st gear, and then press the button to high boost when you are ready to go all out. they even sell a remote switch for your steering wheel so that you can press the button while driving.

Two settings isn't going to bring you to the limits of traction in each gear... but pretty close

for daily driving or street fun, all you need is a good pair of tires. im running kumho asx, and while they are not the best tire in the world, they seem to do a good job griping on a dry road. with 225-45-17s that i have, you can feel the car starting to want to break loose, but still keeping traction most of the time.

the last thing to remember is that its still a fwd car. you cant lauch at 5k and floor it in 1st gear like you can with an awd car.
