come to the strip where we will see real results.

Why do you like the strip so much?

Dyno's accurate enough, can't brake g-boxes and clutches that way...





Actually go to the strip Alex, i would love to see your wagon chop a rex

I would love to go to the drag strip but i'm scared i'll break my fragile little car and not be able to get home

there there its ok you dont have a strip in adelaide so your forgiven anyway.

Alex will chop you .. then ill chop him

Off topic but how much does a VF18/VF13 turbine back housing go for? Looking for one in good condition for a good price.

[Jimbo]

people nearly give away TT turbos these days, im sure you could find a cheap bargain, wouldnt be anymore than $100 surely.

[robt]

Interesting though Jim as my turbos are vf20-21's. And I know they cannot be found on this planet. But If I blew them up 27-28 or thereabouts would suffice. After I drove my mates Blitzen I want those compressors as they have a bit more lag but fork me they go off on sequential.

[Alex]

25/27 for the autos, Rob, or 26/27 for the manuals. Either pair would be sweet. Singleforthewinzomg

Gen3 B4 S401 32/33

Gen3 B4 (Oz) 32/33

Im not 100% but im pretty sure thats accurate.

I can confirm that is 100% correct.

But using the VF33 (Primary) and VF32 (Secondary).... The VF32 has a larger intake diameter, so therefore, not a bolt in proposition. Your best bet is the 25/27 or 26/27 combo.

[B4TT]

How much more power (I know silly Q) would the 32/33 provide over the 26/27 combo? big diff or negligable?

According to Billsy who's tried both combos... the difference is negligible.

Another interesting fact to note is that the secondary turbo is indeed roller bearing turbo.

[B4TT]

Hmmm cool... interesting that you say it deff is, I have heard this before yet the spec sheets for the B4 say its brush....... not saying your wrong either because I've heard it from a few techy people that the secondary is roller bearing

I have read that too, Says both the 32 and 33 use a "Floating Metal" type bearing (quote from the B4 tech specs)

With the exception of the VF25,VF26 and the VF33 which have thrust/2 sleeve bearings, all the other twin turbos are BB.

Incorrect.

Where did you get this information from?

All TT turbos are thrust bearing. BB TT Turbos are VF32, VF27.

[zanzarah]

With the exception of the VF25,VF26 and the VF33 which have thrust/2 sleeve bearings, all the other twin turbos are BB.

This can be easily verified by
1.Using code break on Turbo Master list ie RHF4B. B= BB if there is no B ie RHF4 then it has a Thrust/2sleeve bearing.
2.If you have a free turbo remove the oil drain pipe and look inside the oil gallery of the CHRA.
The BB have a smaller internal port which has a spring separator crossing inside it (compression spring to separate the bearings).
The sleeve bearing turbo have a larger port, no spring and substantially thicker turbine stem.

The VF26/27 will easily out perform the VF32/33 combination significantly.
The VF32 approx!! equats to the VF27.
However the VF33 falls short of the VF26 due to:
1.smaller compressor wheel
2.P11 turbine compared to P14 of the VF26.(more restrictive/less run out)
3.VF26 has better exhaust flow (8 blade performance wheel therefore more run out)
A comparable match up is the PE1016F/VF32 (PE1016F=VF31 on P16 exhaust housing)
Primary turbo guide PE1016F>VF26>VF25>VF31>VF33
Billsy has achieved 107/229Kw ATW with slightly modified (exhaust port)set of VF26/27.
