at what RPM is your turbo on full boost by?

I'm seriously considering keeping my .48 instead of going upto a .63...

What are your views?

thanks mofos

 

go for a .55, best of both worlds, that's what i had

edit: plus each engine will differ at what they come on fully boost at; e.g different cams etc

 

take it ur onabout T34 owners.............

 

If you want more power go for the .63, if your not fussed then there's not much point?

 

my gt30 is nearly as good as a t34.63 for boost threshold

 

3550rpm on mine @ 31 psi iirc and gradually drops to 22psi @ 7040rpm

Pulls well enough from 2500 mind.

 

if you keep your .48, you will need to get your chip spec changed by stu...

i would personnally opt for the .63 in yours mate, which is what your chip is already specd for.

 

thats what i was thinking J.

Whats the difference between a .60 and .63? would i need to get the chip changed for that?

 

.48, .55, .63 are the t34 exhaust housing variants mate,

your chip is speccd for a .63, the compressor maps are vastly different between the types, so its important to have the correct chip for your chosen turbo to get the fuelling spot on

goes well on the .48 tho eh?

 

yes mate, couldnt believe how much different it drives. Just feels more "alive" like its got loads more ignition in it and its boosts SO much earlier. Well good fun.

I can get a T34.60, with a maram shaft. i didnt think they made .60's?

 

they dont mate; its either .48 (standard), .55 or .63 on a t34

 

never heard of a .60,

if your happy with it as it is, simply give stu a call, and see if he can change the spec of the chip.

you could get that maram shafted turbo, and stick your .48 on it...or live with a little less response and gain 20 odd bhp at the top on a .63,

 

maybe the guy means .63 then????

fook knows

J, Think i'll still go for the Larger housing

 

i would mate, tbh it may help your traction issues a little bit, the .48 makes power so early we had wheel spin in 4th gear as it was wet

then just get a fuelling and det check and job jobbed, should be a really strong car then

 

Use a .63 as the T34 works best in that spec.

Cheers lads.

 

mine comes in at 3500 rpm

...????.....u mean full boost dont ya

 

 

can of worms.........

 

thats compressor housing


i would personally go for the .48 you wont see much power gains over the .48 or the .63 imho

the .48 is the housing we use on our 380hp conversions and they fly

 

go for the .63 in my experience.... they are or they were a massive pain in the ass to get hold of though.

 

My 3dr that Karl mapped had a T34.48 and it was a fantastic road car imo, very punchy, was peaking @ 32psi, holding 28.


My mate Martin aka BUD-WEIS had the .63 housing in his saff, when i went out in it it did feel a tad more laggier, BUT pulled bettter up the range, so i guess it all depends on what you want boxxer...

.48 For me...............

 

ive already got the .48 housing anyway.

How can you tell what size the exhaust housing is? is it stamped or something?

 

Yes, from memory there,s a stamp on there...

 

Its stamped.

Jimbo, did your dad ever use the .55 housings, got a similar specced engine here to Mikes original T34 engine and its obviously stamped .48 but it was rumoured it may be a .55.

Whichever it is its a very driveable engine but I need to get the chip checked that came from Stu as it looks like its designed for a .63 housing which ofcourse this engine definitely doesn't have

 

cool. Where would it be stamped then?

say it DOESNT have a stamp, how do you measure exactly what a .63 housing is???

 

I've not got a pic to hand but if you look on the outside of the exhaust housing you should see it, I am 99% sure its easily visible.

Can't answer the other question but wouldn't mind knowing that myself !

 

I'd like to have a go in your car please one day soon rich... I might go for one of these soon on current engine before going for nutty bhp

 

Of course lee. Once the diff is fixed, the alternator is fixed, the tyres dont scrub the arch and any other problems that i need to fix

 

and 450hp isn't enough in a Westfield

Crazy

 

lol,

Lee are you in danger of making the Westy too powerful or is there no such thing in your world?
