it's been a while since i had any involvement with bentley

i was just reading about the arnage T having recently changed from garrett turbo's to "42 % faster reacting" mitsubishi ones "with 52% less inertia"

was the T fitted with 2 T4's, or is it te R & RL that have a single T4?

I allways thought it was x2 T34's they had fitted bud. Got a lot of mates back home who work at Bentley. A good mate had fitted a Bentley spec T34 to his saph if you get me.

I can find out for definate next time i am home if you want. A bloke i knew a few years ago made the engines on the Conti GT but not sure what turbo's they run.

Just asked my Old man and he's sure they had a T4 on the old Turbo R but doesnt know if they Changed this for the Arnage T.

He also thought the Turbo R only had a single turbo. I told him the Arnage has 2, he said i havn't got a fooking clue then

They not T34 or T4s as we know them, ie they not the same as Cossie ones.

T34 and T4 means nothing really, just general designation for a rough turbo size.

An RS500 "T4" is a T3/4 too, large T3 sized exhaust, small T4 sized compressor.

Without seeing the exhaust manifold flange you wont know if they true T4 (id expect they are at least in single turbo form though), but the ones ive seen certainly have T4 sized compressor sides.

Small T4 size tho, like EscCos, RS500, and RS200, turbos.

i was just posting in case the information may be useful to anyone who has or is considering a t4 sized (whatever that is) turbo and can find out more about a more responsive version

Rick

T4 surely designates the exhaust wheel size. A t34 is a t3 framed turbo, the t4 on a 500 is larger everywhere.

rick an rs500 to4e is a t3 core with bigger bits on each end

Rick

the bits at each end are the important bit lol.

Does that make it a T3?

With GT's - at least the naming scheme makes sense!

Stavros

No, T2/T3/T4/T6 (no such thing as T5 it seems) designates FRAME size, ie HOUSINGS.

Both EscCos turbos and RS500 turbos have T4 compressor sides and T3 exhaust sides.

Is the manifold flanges on them turbos T4 ones Rick?

Just RS500 ones are bigger than EscCos ones.

But both are some of the largest "T3" exhaust sides around, and some of the smallest "T4" compressor sides around. Some T4 compressor and exhaust sides are capable of over 1000bhp.

T04B is EscCos compressor housing isnt it? (ie 2.75inch in, 1.75inch out?)
T04E is RS500 one i think? (ie 3inch in, 2inch out).

Please excuse my ignorance, but am i right in thinking that what you are saying is T3, T34 and T4 are all fundamentley T3's but with differant exhaust housings and compressor housings?

Carlsworth

yep
and dfferent compressor wheels, and back plates..


hence the 3 in T3....and T34....
also, a RS500 t4 part no is T04E/T3
carl

Stavros

As per what i said earlier, read my posts, i explain it all.

None are full T4s, but only the T3 is a T3 as such, the other two are T3/4s.

I even already explained the T4B/T4E thing earlier that Carl has just repeated again, but in more detail.

phill2400

I have a new t4 to fit a bently mulsane if any body wants one.

Carlsworth

elaborate on

if anyone wants one


if its "in the way"

im happy to take it off your hands...

Twellsie

iTrader: (1)

so can you convert a T3 into a T34 just by changing the housing?

Carlsworth

yup
and for a good price

also needs different back plate and compressor wheel

lol

phill2400

would take £50 for it could be handy to you .

Carlsworth

you have pm

Stavros

jesus you never heard of ebay

idve took it if i thought you wanted 50notes
