What is the advantages of having cut back blades what do they do

 

Pm Wilky. He knows a lot about turbos

 

from cutting back the blades i think it allows the turbine to flow more gas through it so there will be less resistance there, but it will be laggier as the surface area of the blade is smaller.
i may be wrong but i think thats what its for, to basically make the turbo so it can flow abit more air and make abit more power at the expensive of abit of lag.

 

It was to reduce turbine shaft speed at high boost levels the by product was increased exhaust flow and an increase in power
They were laggier obviously but were used in the early era of als

 

Ah right ok I have just got a rebuilt t34.63 with cut back blades and now the boost doesn't come in till 4.5k and it's horrible lol would a new chip and setup sort this out?

 

Would I be better selling the turbo and buying another std one?

 

I'd change the housing maybe?? Surely a .48 housing will improve spool?

 

i think you should swap it for my T3

 

Dan,

TT Stage 2 T3 is a cracking blower bud

When mine was on the NMS Gunship live map i loved it

 

What would it be like over a std t34.63

 

I used to love my t34 untill it started to smoke bad so bought this one

 

Well obviously you're not going to make the power Of a T34.63 for starters, BUT you'll have instant respone but it will die at 6-6.5k revs.

Depends what you're after and what you want to use the car for, imo a live mapped TT Stage 2 T3 car is a great, punchy road car, but as said you'll make 310-320 max, if you want 360-390 then stay with what you have.

Hope this helps

PS, T34/48 is a great inbetweener

 

I love the punch my .63 gave me and I like a bit of lag I want 360 plus as well so I will prob sell it on and get another one or change the housing for a .48 and keep the .63 as a spare

 

i would say it will be the best of both worlds.
with the 0.48 housing you will have the smallest housing to aid response but with the cut back blades you will have a more efficient turbine wheel to help it flow better, dare i say it may respond like a standard t34 on a 0.55 housing maybe ?

as you are now you have the potential of maximum power from the turbo but maximum lag to go with it.

 

You're hard work, all that you've posted above is what this thread is about

Leave it on then if you love your .63 and lag

 

Lol I mean I loved my old one it came in full at 3.5k that's a bit of lag this one tho is too much lag for me lol

 

Would there be any way to get this turbo to come one earlier

 

2 bar through a T34.55 aint bad either

 

yes, as said above fit a 0.48 exhaust housing.

 

I mean with the .63

 

roller bearing core??

 

you'll just have to rev higher

 

Might just fit my old smokey one for now and sell this one on an with the money get mine rebuilt

 

as said the cut back blades help stop reduce over speed when restrictors were run on rally cars

 

Gonna chuck a 48 on it and sell it on I think

 

Cut back blades were there for the high boost levels in rally cars to prevent the blades touching the turbo housing and causing all sorts of trouble.

I had on my saphire stg 2 cut back blades and it gave this all or nothing effect awesome in the dry scary " for passengers" in the rain.

 

so you have increased the size of turbo and the amount of air being produced is greater.

Hope your not running the same amount of boost.

More air = more fuel and any turbo change will require a chip change.
