Tdi feelin the heat

[extreme90]

hell yea,
ya no that intercooler is there  :lol:  full width, the low down power is unreal
and it throws 35 inch simex with ease even on std 90 gearing  :shock:
will nearly tone up altho i dont reccomend it  :lol:
only testing them  :lol:
its just abit 2 fast in low tho  :(  so need alter the diff ratio's
still pondering what ratio best tho  :roll:
any ideas ? tim ? 4.11 or 4.75

I got my manifold on my old two and a quarter series 2a glowing bright red trying to do 70mph then realised that the radiator muff was fully up when the temp went of the scale.... :shock:  :shock:

[extreme90]

:lol:
matt had a experiance of the red stuff last night  :lol:
when his 300 overheated and he ran it for 5 mins aswel right in the red  :lol:
lucky sod no damage been done
if it was me there b a big gob off ally in the engine bay  :roll:

cuz we lucky  :D

I've seen pictures like this before on development engines, it's not uncommon for them to glow but a bit of air circulation works wonders you know.

That's not hot....

You want to see the manifolds and the exhaust on an engine on the test beds at work when we do full load work...
They get that hot you can virtually see through them!!!

On a petrol you just dump more fuel down the exhaust (i.e. run it rich) and/or adjust the ignition timing....

But on a diesel it's the other way around... more fuel = higher temps (thus EGT)

Anything above 800 degrees on a Tdi or Td5 and you start getting towards the material limits for the cast manifold (hence why you get warped manifolds on badly tuned diesels)... much more than this and you will also find the fins on the exhaust side of the turbo will start to break up, and in extreme cases so will the exhaust valves!!

In saying that, in the short term, and for short blasts you will get away with higher temps.... I've known 300Tdi's that peak at 1200 degrees!!

on hill climbs ect ian ?
im sure on a 2 mile run at that temp, the next morning its gonna b goosed  :roll:
ive just been suffering with the oil pump shaft coming out of place and getting no lube another new turbo
and then the oil cooler pipe burst resulting in another engine rebuild and another turbo  :roll:
all good fun
spare engine and turbo now  :lol:
for when things go t**s up again
but its sods law now i got um itll never happen again  :roll:

 where i used to work they had a rolls royce genarator set at full chat in the dark you could see the shadow of the pistons going up and down :shock:  :shock:

[extreme90]

now i bet that looked good
a 27kva diesel gen does that aswel in the dark after its been running all day  :lol:
might have a dodge over the farm tomorrow night and take a piccy and one of my 90 after a thrash  :lol:
see how much it scares me  :shock:

our fan belt ripped itself to bits the other day... can i have a prize?  :D been on its way for a while, along with the power steering belt.. had replacements just not been bothered to do them... gave me a bit of a push and did them today lol.

who the hell designed the alternator without one of those little square holes to fit a ratchet in?

Why an EGT guage is handy  :lol:

so was that a standard camera? not low light or owt?

standard mobby cam,1.2 mega pixle on normal settings
on night mode it was too dark :lol:

[Evilgoat]

After a long, hard motoway burn the Audi used to glow like that. Who needs under-car chav lights. New exhaust setup all I get is a dull red glow now.

Had a pic of a cossie being hammered somewhere.

Yes, thats WHITE hot :)
