redlined loss of boost

[JamietypeR]

hi guys took my mazda out for a spin today, temp was normal 85c, was on a long straight at the bottom of my garden................. and was going thru my gears redlined it in third gear as i was about to take it back and park it up for a couple of days,  and after lost boost if i put my foot down i get no power, and temp went up to 105c, any advice would be much appreciated.

popped a hose clamp off intercooler?

as above : Check all silicone couplers on your intercooler setup one could have split or come loose,

Whats the spec of the car so we can give you better info?

Cool I didn\'t even think of checking the intercooler, it\'s running apexi ecu decat pipe and apexi exhaust.

[JamietypeR]

Jus checked the intercooler and can\'t see anything loose or off and theres a really strong smell of fuel when driven?

[m1tch]

Could maybe by the OEM wastegate actuator giving up and letting the wastegate open at high gas flow like mine does, whats the boost set to?

[JamietypeR]

Er!? Not sure dude, I haven\'t reached more then 8.2 bar boost so I\'m guessing around there.

If there is a really strong fuel smell then I wouldnt drive it if I was u, last thing you want is it to be a ball of flames.

On your apexi comander, do a sensor check and see if any are out, only other thing it could be is a rats nest soleniod, thats where my knowledge runs out as ive never had a car with it.

All sensors are fine on the apexi, where\'s the solenoid for the rats nest located? Could the standard intercooler of popped?

Take the bottom hose off the IC and check it for spliting as they are known to split.
Also check the coupler by the Y pipe as these tend to go aswell

Ok checked all the hoses that come off the intercooler n no splits, put it all back on and the second turbo kicks in ok but there\'s nearly no power from the first 1 on the apexi my highest point in boosting was +0.81 which I\'m guessing from the second turbo n the not the first

[JamietypeR]

Also my temp is going upto 98c is that normal?

[G@NDY]

High temps and no boost could also be a blocked cat. Ignore this however if you dont have one

[JamietypeR]

Yea no cat dude it\'s straight thru

[rx7boy]

Have you checked your coolant level, if its low that will be the reason for high temps,

Sounds like a rats nest issue, cause if the second turbo is coming on then its most likely a solenoid
