Adjusting PTE Actuator

[tbauer03]

Last time I went to track I used a bleeder valve and had crappy boost control. and everyone recommended just using the pte kit. I still got the bleeder in the system but the spring is unwound and pretty much useless and the pte actuator is doing all the work. So if i want more boost, all i got to do is shorten the rod to increase the pressure. Anybody control boost like this.

Re: Adjusting PTE Actuator

you can increase or decrease boost by manually tightening the wg rod, however most people end up running 18+ psi at the track, and dont feel like getting dirty just two alter the boost level a few pounds.. Setting the base boost to 17+ psi would require a heavy duty actuator and most likely compressed air to freely move the actuator rod.

The only reason you may be expiriencing crappy boost control with a manual bleeder is b/c a) your bleeder is broken or b) you bought a cheap home depot style regulator.

My recommendations is to buy the turbonetics manual knob if you want precise boost control with the pte wg.

thread jack!------mike, wheres the best place to get boost signal for the turbonetics controller? ive got one but no matter whick way i turn the knob doesnt seem to do sh!t. and it acts like a centrifigal(?) blower. boost goes up with rpm to around 10-12? any ideas?

Re: Adjusting PTE Actuator

anywhere you have a positive boost reading.. ie compressor housing, intake manifold before or after the TB. doesnt really matter. Just make sure it is not after a check valve (cruise, hvac, vacuum ball, charcoal canister, etc) They only see vacuum.

FYI, you should only be seeing boost when there is a load on the motor (in gear), and it will climb with rpm.

the inst say the signal must be after the tb, and i no that no load=no boost but with the stock setup itll go to 15lbs at say 3k rpm and stay there but with the controller it slowly ramps up to 12 or so at the top of the rpm range.?

Re: Adjusting PTE Actuator

well its fairly simple to troubleshoot if you have a broken controller or not.

pull the line off the compressor housing to the wastegate actuator so nothing is hooked up.. It should overboost VERY quick. Hook back up the line directly to the wastegate. SHould make 8psi steady.

Seeing an overboost with no line, means the wg is shut and doing what it is supposed to.. If not you have a boost leak. By applying manifold pressure to the top of the actuator, the wg is now opening (not stuck) and if it holds a steady 8psi, chances are your exhaust is in order and you probably dont have a gutted cat.

At that point i would think bad regulator.. Just blow into the "IN" side of the regulator and while blowing turn the knob.. you should feel it gradually getting easier or harder to blow.

hope that helps.

Re: Adjusting PTE Actuator

thanks ill try the troubleshhot this weekend, im 99% sure the wg in good but ill check the regulator. btw the ghettosled is badass! nice work
