Fitted boost gauge and now manifolds glowing red! (Now sorted!)
Can someone shed some light before i torch the fucking thing 
Been doing various work over the last few weeks but one of the changes was fitting a boost gauge.
The actuator seemed to have too much preload as it snapped the bit off the top of the wastegate arm that the actuator hole hooks onto.
So i slackened the actuator arm off. Welded the top bit back on to make it stronger. and hooked the actuator arm back on.
Ive wound it down to 20psi which is what the gauge is reading. but its now glowing the manifold red hot and popping and banging on full boost.
Is there a chance the T-piece i used to plumb boost gauge in is a wrong size and causing this?
Im also running the same amal valve as i always have.
I can remove the t piece and go back to original but then i'll have no gauge and will be wary it may change boost pressure and go bang
Any ideas?
Want to take it to USC and fordfair but not at this rate

Put it back to how it was and if it cures it you've found your fault.
Wound it down to 20psi, what were you running before and how sure are you if you had no boost gauge? Are you sure you haven't wound it UP to 20psi?

No it was set up by Jano at Oddkidd with an oil filled boost gauge to hold 23psi. Its a T34 on greys. Ive never run a gauge because i had it set up properly and didnt plan on having to play with it.
Hhmm maybe boost gauge vacuum pipe has a kink so its actually a lot more boost than 20psi. will go check it out quick.
If not i'll just wind actuator right down to what would be around 8psi and remove t piece to see if it boosts ok.

That's where they're normally connected to give a vacuum reading as well. It'll normally read higher at the turbo as you have inlet restrictions between there and the manifold. On an old car I had there was 3psi difference.

Oops just realised ive always ran it from take off on inlet on my rs turbos so dont know why ive ran it this way now 
Will sort it. Guessing thats why ive been getting a false reading and its maybe been boosting a lot more?
Still running really hot though? Ive put new rad on but its not blocked as i ran pressure washer and hose pipe through it fine before fitting. bleeded it all correctly and its not burping anymore so guessing all the airs out?

Right.. So im a retard..
Luckily had the right fitting to pipe the boost gauge to inlet properly. just been out (to my neighbours joy) and set the boost to where it should from when it was set up to be and its boosting perfect!
So the scary part is that when i was out earlier and was getting such a false reading from the gauge it must have been boosting silly psi to have made mani glow and pop and bang. luckily it was just in second gear a few times. but in 3rd upwards i could have easily blown my engine it was so lean! So thanks guys for your speedy late night advice
Bled coolant again and its much better but still hotter than id like. gonna replace thermostat in the morning and cross my fingers.
Right off to finish a million other things on it now.
Thanks again

what temps is it running mate? mines always hit damn near 100 degrees before the fan kicks in and is running hot all the time at the mo (not overheating) due to the hotter weather we are having, in winter cruising i rareley go over 80 degrees even on a run and thats with a 500 style cooler blocking the rad lol

Sadly i cant say what degree it reaches as i only have factory ford gauge.
if its warmed up and i boot it through the gears then stop, it will have crept up to 3 quarters on the gauge. I have my fans on a switch so often have them on. im just dubious as last year on track at ford fair it was just below the red for the whole time and that was with water wetter in it too. Not sure if its worse or not.
its a new rad that doesnt leak. fresh summer coolant, and tomorrow morning im gonna replace thermostat. nothing else left to try really!

ford guages are not very accurate at all mate, id fit an after market one, at 100 degrees mine on the ford guage is less than half way but i have mates that show 70 on aftermarket and two thirds on the ford guage
mine doesnt even start registering temp (on ford one) until its hit 70 degrees
might be worth investing in a new coolant temp sensor as well
