hot side is hot

[D1 WTF]

i have a t70 single tubby, is it normal for the hot side to be glowing red hot, when i stop.  

i popped the bonnet and it was glowing away.  i havent been REALLY booting it, i was a little but not all the time.  i was only driving for about 20 mins.  (and it had been not run for about one and a half hours previous to that.  eg it will have cooled down majoritly by the time i got back in it)

like i said is this ok, are the bolts that go into the hot side supposed to be a white ish colour?

Its possable if you have been giving it some stick, worrie if it does it all the time of load as well as on.

You may want you put a Turbo Blanket and Heat rap round it, may be causing a Visous Circle.

Has it all been set up now??

[D1 WTF]

yes, except on the way back my exhaust (rear section) where the pipe is welded onto the back box if you get me, has started blowing where there must be a hole, can feel it blowing if you put your hand around it.  
insidently this cat back is the only part of the exhaust system which i havent changed in the last 2 months, dont know how old it is as it was on the car when i bought it.

[D1 WTF]

may be causing a Visous Circle.

in what way?  make it hotter.  

when i popped the bonnet i didnt expect to see this big red glowing thing

Well we are getting closer to Xmas you know.........wasn\'t a Reindeer was it. :flamed

LOL, all Turbo\'s glow if you abuse them, the Twins do it but its so cluttered you can\'t see.

If its just been set up ring them up and ask about it? It could be that its Running Weak but as i say its more likly its just been abused.

in what way?  make it hotter.  

Basicly becouse the Turbo is right next to the Lower Inlet manifold, Turbo gets hot and warms the Inlet charge up causing the engine/Turbo to get Hotter etc.

Thats why its a good idea to rap the Turbo up so the heat stays away from things that should be kept cool like Inlets,Pipes and wires.

[D1 WTF]

but then surely the tubby stays hotter

[Grizzly]

The Hot side stays the same temp, Think about it all you are doing is keeping the Hot bit Hot and that heat away from things that should stay cool.

Its better that the Hot side of the Turbo/Exhaust gets hot rather than the Inlet on the engine side of the Intercooler.

[D1 WTF]

so are these bolts suppose to be white (from heat i think)?, i am assuming so?


my exhaust is blowing from here, my perfectly to scale acurate drawing.  grrrrr, do you recon it could be repairable

[Grizzly]

Urm i\'m not seeing your Drawing at the mo (but i\'m downloading so it may be me)

Thinking about it if its a New turbo the Bolts may have some sort of Anti corrosion coating (like zinc) that makes them white when you heat them up?? (just a guess).

Are you using a V-band Clamp on the Exhaust?

[D1 WTF]

my only worry about all this is something sounds funny when i was driving this evening, it is when ,my foot is  on the throttle (not floored just accelerating) thought there is like a tapping (prob being paranoid), but there is a blowing sound that sounds like it is coming from up front not back, but the back was never blowing before, i think it is just that and i am being very paraniod.

will see if i can get someone to look at the back section tomorrow, see if there is any chance of repairing it.

That "tapping" noise you describe is exhaust blow for sure.  Just a case of finding where.

If the gasket has gone on the manifold/turbo, that would make the noise and blow hot air around the tub which might make it hotter ??

[D1 WTF]

will have to check tomorrow, seems odd that the gasket would have gone as it is all brand new and fitted 3000 miles ago

Could be comming from anywhere.  May even have developed a crack in a minfold or something.  But I would be v confident that is an exhaust blow..
