As topic says I am a noob, so please no flamming :)

This morning car felt fine, this evening went out and when I put my foot down to accelerate there is no power when the turbo usually kicked in at 2500 rpm. I haven't done anything differnt than earlier in the day. The turbo gauge is going from -1 to 0 and no further. Had a quick look under the hood and couldn't see any leaks etc. Any idea's what could be going on?? Im thinking a trip the mechanic is in order.

Thank you for any advice

I concur with hyper gear, take of the dump pipe and look at the exhaust wheel

Im assuming this would have been the first thing you would have checked and as noone else has mentioned it have you checked all your cooler piping. When they blow off they can make a loud bang and then no power. Other than that it sounds like it icould be a turbo matter.

could also be a wastegate issue. if the wastegate is stuck open then that will dramatically affect performance. i had a boost controller once that would hold pressure between it and the wastegate so when you changed gears you would have no boost in the next gear.

so undo your wastegate actuator and see if it is moving freely.if it is, then also check you vaccum lines to make sure there are no blockages between the wastegate and the intercooler pipe.

then if that is still ok then pull off your dump pipe and check the exhaust wheel

Nope, it wouldn't be the cooler piping as the slightest leak in the cooler piping, and the car will not idle normally.

The fella mentioned it's idling normally....

Either the gate is stuck open, or the turbo is f'd

    • Kinkstah, no, coilovers aren't illegal, especially as a bolt straight in. The illegal part will be if they're altering suspension geometry beyond factory limits, or the ride height is not legal.   Sounds like the blue slipper just didn't want to deal with any later possibility of mods appearing on the car.
    • The problem has always been that coilovers are able to be adjusted, almost at any time, to be too low. Most people who ever get/got defected for/with coilovers were actually afoul of the minimum ride height rule. So the interpretation by cops/inspectors was always that it is pointless to allow numpty to raise his coilovers and get the car inspected/cleared, then just drop them back down again as soon as they get around the corner from the inspection station.  This led to the interpretation that they were illegal unless rendered such that they can't be adjusted (ie, collars welded to the body, that sort of thing). That may or may not have ever actually been the official line, but I'm pretty sure it's not considered to be a solution these days. Coilovers themselves fall under clause 3.2 b of that manual, because they are an "installation of a variable ride height system" and they don't fit the exclusions in that clause (which point to air springs and other pneumatic adjusters). So, as per previous statements, they require engineering cert to be legal on the road. Once you have such cert, provided you do not adjust them outside the height range covered by the cert, you are OK. Without, you have an unroadworthy vehicle.
    • Here E10 is the cheapest fuel. And general advice is to not use it unless you hate your car. From what I remember it clogs up stuff in the fuel system or injectors?  With US/Canada being E10 across the board, does that mean that all fuel there is terrible?
    • Sorry, are coilovers ACTUALLY ILLEGAL in NSW? They aren't in Vic, as long as they retain 70% of stock travel and the car is above 100mm off the ground. Does NSW actually have a law making coilovers actually illegal? RWC/Blue Slip/Engineering people not knowing the actual f**king laws boils my blood. Demand them to point to the documentation that states a coilover is illegal. (it may exist in NSW ) Edit: I checked. They aren't. https://www.nsw.gov.au/sites/default/files/2021-02/RMS-infosheet-light-vehicle-modifications-manual-suspension-and-ride-height.pdf
