hi a rs 500 t4 with a ar 48 back housing would 400 bhp be its limmit because of the back housing

 

A 5litre V8 would possibly be its limit because of surge.

 

 

It will be surge-tastic

400bhp seems a lot for a .48 housing too, would have mental backpressure.

Shittest combo ever IMO

 

so a 63 would be a better

 

A .48 housing won't fit on a real RS500 T4..

 

 

 

 

why not?

 

 

Turbine wheel is different.

 

why all the remarks i was asking a question

 

DaveAVT
your right it wount .its a t4 comp housing and comp wheel and back plate bolted on a t3 with a 48 back housing

 

Different to what?

And how does the fact its different to something stop a .48 housing from being available for it too?

 

This will no doubt be why your asking the question?

i take it he only means a .48,we usually associate on the cosworth engine wont physically fit as the T4 on the RS500 has a much larger diameter exhaust wheel i have tried the combination he has mentioned,basically a T3 style turbo with an RS500 compressor on and never had any results worth writing about,thats my opinion anyway

f@ck it,put it on,at least it will look good

ok any more info on using it with a 63 back housing

 

Different to the other 99% of cars that all use the same 59/48 T3 turbine, saabs, volvo, renault, ford, buick etc....

The turbine in the RS500 is a T31 HL wheel, larger exducer, heavier trim. They never made 0.48s to fit this wheel, as it was a mainly motorsport application - 0.63s upwards... The same unit was used on the Renault 21 Europa Cup cars...

Any more questions???

 

..so, any 'RS500' style turbos you see with 0.48's are simply Cosworth 2wd turbos fitted with a T4 cover, backplate and comp wheel...

 

DaveAVT
so will the t4 front end be ok with a 63 back housing .its got to be better than a t34

 

my magical hands can make a t4 shaft fit a .48 cos housing












Would be a waste of time though

 

Yes, it will be roughly the spec of a T38..
