Girgor sent me a PM today saying about this.

Anyone ever heard of this being done?

I think this is how it goes....

Open the wastegate on the turbo and the exhaust gases should go out of that instead of spinning the turbo which stops making compressed air and results in the slowing/disabling of the turbo?

Does this work?

Does it do damage to your car in any way?

What is it like when the turbo does kick in if even?

Any info would be great as I'm a little confused

Thanks

What you said is right, goes out the wastegate hole before spoolin up the turbo, just not all of it.

No damage to the car just less air going in so ECU will fuel-up as necessary.

How you would do it i don't know?

Why would you want to?

Cool, ah it's just because I'm a inexperienced drive and would rather ease the boost of rather than start off with it fully boosted. It depends if I'll do it. If I can control the power than it will be fine and I'll just leave it.

Maybe you should of purchased a different type of vehicle if your in experienced? Like said above a civic.

exactly.. shouldve bought a civic... its ppl like u (not directly u) who go and purchase hipo cars without even knowing how to drive (any monkey can steer a car, thats what driving is about) and then go and get urself killed and other ppl giving the rest of us a bad name

u should sell it, and buy a civic champ b4 u do anyone any harm

i had a problem with my boost controller where it was holding the wastegate open when you changed gears. so in the next gear you would start to get positive boost at about 5500rpm. it was gutless. there is a hill just out of town where if i boosted it from the bottom i could normally hit 100kmh by just before the top, but i was boosting up it when i first discovered the problem. i hit third at about 80kmh and no boost. by the top i had dropped back down to about 60kmh. it was a pretty steep hill.

yes disconnecting the wastegate flap will give you no boost, but it will also make the car completely gutless. it would be like driving a natro that has done about 1,000,000kms and is due for a rebuild.

if you are really worried just disconnect the high boost solenoid. but it standard form they aren't that much of a handfull. i went from a manual magna to a stock manual 33 and was rather dissapointed. i thought it would actually notice a decent performance difference but i didn't. it wasn't until i started modding it that it actually seemed to have any go.

its just mate if u cant control the wow of a R33 gtst which in my opinion is a gutless overweight barge like all R33 then u have issues with driving.. how old r u..?

but having the GTST will make u learn quicker.. now try holding the right down at full sing in a GTR around a 40kph corner in 2nd.. and that is where ur schooling takes effect.

Yes, replace the actuator spring with something that opens at 0psi and then use a boost controller of some sort to make it run more boost when you want it. It won't damage the car - with no extra air going through the AFM the ECU will still find itself within its standard parameters. It might throw up error codes if it notices that its not boosting when it should, but in a pure "mechanical failure" perspective it should cope with being run permanently off-boost.

Of course, your car will drive like shit. You need to run a certain amount of boost to make up for the intake restriction that is the compressor and intercooler piping. The engine would run worse than NA if you set the wastegate actuator to open at 0psi. Couple that with the taller final drive from a car set up to expect more midrange, and you'll get something that even a Camira driver will think is slow.

But, as other people have said, if you don't think you can drive a turbo car then don't. You had another thread trying to get some kind of electronic speed limiter, and now you're trying to un-boost a turbo car. Have you considered that the common thread (and the easiest thing to replace) in all of your car-related problems is, well, you and your choice of vehicle?

not only the added restriction of the turbo and the cooler but the lower compression of the turbo motor. at 0psi boost even at 5000rpm they couldn't pull a drunk sailor off your sister.

just take off the hig boost solenoid, leaving it at 5psi. if the car is only stock and at 5psi you won't be much quicker than a commodore. if that is too much power then i can sell you a push bike.

I've always wondered about that phrase.

Considering how long he's been out at sea with only his hand for company, I reckon it'd be really hard to pull a lonely guy on shore leave off any piece of skirt that showed an interest and a pulse.....

And yeah, I forgot about the compression ratio thing.

yeah i always wondered too. it is a bit like "cheap at half the price"........ most things are cheap at half the price.

      Biggest thing is you're okay!   It sounds like between the accident, and the drive home, it was a pretty torturous trip again! On the bright side, you took the opportunity to enjoy the event more from the perspective of a spectator, than as an entrant!   Sad to see so much damage to the car. It really has taken a HUGE hit in the front end. If/when you choose to repair, hopefully the rails are straight (At least from shock tower backwards). Hopefully the extra cage coming through there has save most of the chassis rails, and HOPEFULLY saved the motor too. Best of luck when you eventually get motivated to start pulling it down to check it all out

      Slight brake pedal stutter after new pads

      By MBS206 · Posted

      Sounds more like what Brad said, that it's mainly transfer. What pad bed in procedure did you use, and did you replace/machine the rotors, or just swap pads?

      By PranK · Posted

      The stutter is almost entirely in the pedal. I don't feel the brakes release and reapply as you would with ABS engaging but the pedal feels that way, without the brakes releasing. It only lasts for less than a second and the pedal is fine again. It's hard to explain, sorry.  I'll get under this weekend and just double check everything is tight. Fluid is at max where I left it.

      What bedding in procedure did you use?   When you say stutter, what exactly do you mean? Like it feels like someone letting go of the brakes momentarily and regrabbing them again to get you to stop? Re-reading your post, and that is what it kind of makes me think you're explaining, like theres a little bit of a jolt, likely just as you're reaching a stop. I've only had this issue once. And if its caused by what caused mine, you will want to get the car up on stands again and check it over. Mine was a case of a caliper mounting bolt coming out and letting the caliper rotate on the other remaining bolt and gave play in a wheel as it came to a stop. But not every stop either!

      Yeop... binned it   This will be a summary will not many pics atm and cbf  Fixed the samsonas - it was totally munched Put a new precision 7675 T4 on with proper split pulse mani Got to Sydney to get to car - drove to canberra to get racecar - drive back to sydney that night Next day all day at Plasmaman putting on new clamps cleaning some things up and adding another large engine oil cooler sitting at the rear above diffuser to keep things cooler Next day - Tuesday - on Dyno - killer wikid awesome pumped out really good numbers - more mid range and on lower boost levels Wednesday - first prac - all day again getting the suspension right - had to borrow front suspension again - out do a lap come in - out do a lap - in - what i had just couldnt handle the load at the more consistent higher speeds - got a lap in at the end of the day that was pretty reasonable  Put it this way that lap wouldve had me in 4th in Pro am for the whole event - with only 700 hp and used tyres Thurs first official prac day - lap out warm up - then entered a hotlap with above setting and 80% effort took corners 1,2,3 and into 4 car felt awesome -  rear came around out of nowhere bang into the wall near front on at whatever 140 kmph Done, over, gone Just one of those how did that happen apparently as all indications show nothing out of the ordinary Got to spend the rest of the time at the event like I hadnt done before - was actually Ok mainly as I had my family and my boy is 9 and got treated like a rockstar Long trip home, lost a trailer wheel in nowhere land, X5 airbag suspension gave up half way across nullabour and rode on bumps stops (its now completely fine) had to do a 19 hr drive day on day 3 as accommodation got screwed up so just had to keep driving till found a town with some Now to reassess - hopefully the motor and other things are OK but yet to be seen too. There is no easy fix there is no i'll just order that part and get it sent - we'll have a talk to people see what can happen and what the go is but at minimum its rebuild from scratch struts forward and alot of time effort and $ should and if I return and if but maybe/ when  I have the cage tied into the front strut towers - if I didnt have that things couldnt been worse you can say its just a front end but if you know what goes into these cars... you'll know what that actually means in reality   Car was very fast. Disappointing we just didnt get to show it Effort doesnt win you races though     Apparently this is motorsport !
