quick low down on the differences anyone? power also?

turbo's seem to confuse my small brain.

cheers anyone in advance

 

do a search........but a 34 and a 35 are the same..........t34's come with 3 exhaust housings.......48 .55 .63 and the power increases as u move up.......and a few companys do t38's..............with different sizes/power levels aswell......................bet ur even more confused now.............

 

thanx for replying!!!

indeed im more confused but a bit clearer too if that makes any sense....

so 38's are for more power than a 34? whats the most power you could achieve from a 34? would it need a .63 housing for maximum power?

 

also why do they call it t35 if its the same as 34?

 

T34.63 can do 400 bhp thats what i have on mine,but been told it won't last long at that power.

 

Yes you need a .63 housing to get max power from a T34

 

this is where u need to talk to a tuner about what u want from/out of ur car.......do u want low down response or do u want top end power.....or a nice inbetween...??????

 

ah ha i understand!!!!

 

in regards to responsiveness is this set up top end response. low down or inbetween?

 

not a bad choice if set up right.....................

 

the larger the ex housing the later it will make boost,ie a .63 will be more laggy than a .48......but the .63 will make more power as the boost is produced at higher rpm

 

there are also various forms of t38,but generally they are a .63 ex housing,with a modified t34 comp housing.which will flow more air.

iirc,they use a t4 comp wheel....

 

..........not entirely true.....most people think of a t38 as a big old t4 looking thing....it's the recent turbo companys that have modded t34's to make them more responsive....mine is a universal turbos t38.......t34 front (machined out) enlarged front comp wheel and a t4 arse end......(so i've been told)......

 

yeah....like i said.....63 with modified t34 comp housing

the tt t38,looks like a t4,but ut,or harveys looks externally like a t34.63 but they have a t4 comp wheel hidden inside.

 

The .48 housing i had was low down power but tailed off top end,.63 housing holds the power to the limiter,not much laggier than the .48 housing either.

 

...........was on about a tt t38....the big one.....(old school)

 

think there's turbo dynamics aswell......(big un)

 

ive heard a few peeps complain the big t38s surge...and need mapping live

 

wouldnt ever have one.....................would just go t4.....(new style)

 

sounds excellent with the .63 housing. probably gonna go down that route!

 

the t35 is only called that by turbo technics as its a t34 with the .55 housing,middle of the road job

 

i assumed so

 

a t38 is a excellent turbo pull low down and makes good power an overall brill turbo.
when specced right they will not surge and there is an off shelf chip for it also so no live mapping needed

 

How do people rate the .55? Will I feel enough of a difference to warrant changing from a .48 before mapping? I like the punch of the .48, but a bit more grunt would be nice.

 

u wont notice much difference i have gone from a .48 to a .55 no real difference in lag,it does hold on better then a .48 but not a big difference
