T28 makeing car jerk after boost dose it supose to do this?

[l3igl3ang]

yeah when i boost my car and take my foot off the gas a little then push it back in the whole car will jerk is this normal?

When i remove my foot from the pedal then push the gas it dosen't do it.

Uhh what ?

 

[MountainDew]

That's pretty normal for any car.. considering you're not keeping the throttle consistent nor smooth.

I don't see a boost guage in your profile. Do you know how much boost you're running?

 

[viperlp01]

Ya that is normal because your at that power range under boost. When you let your foot off the gas you lose boost and when you push the gas again you are at that power range with-out the same boost levels. You are going to jerk until the turbo matchs it. All turbo's i have been in does that.

Not ALL turbo cars do that. Just ones that have poorly tuned part-throttle areas.

could also be a bad motor mount causing the motor to shake/jerk

You say you have a T28, but it's not in your profile. Update your profile. That will give some of us more to work with.

 

[viperlp01]

well i haven't been in a super tuned turbo my fault but you get what i mean

 

[l3igl3ang]

yeah got a boost guage doing around 10 to 11 psi

Supras cut fuel if the boost goes too high. He's talking about the fuel cut defender which will prevent it from cutting out like this.

What the thread creator was talking about sounds like it's just a poor part-throttle/low-boost tune. Easily fixed by someone who can tune good.
