Benefits of a 18G wheel

[Ryan]

What are the main benefits of a 18/20G wheel over a 16G wheel? Looking at buying a TD05H-18G instead of the standard TD05H-16G.

More output higher in the rev range without sacrificing spool up speed?

[Ryan]

Just a bit worried it will take away some of my bottom end..

[Guest]

Are these china turbos your looking at?

They are bigger so they can make more power potentially. It will take longer to spool up.

Your probably not at the limit of the 16g atm.

What about a 22g wheel? Lag special?

22g 20g even 18g will not suit a stock or mildly modified ride, a 16g will outflow a stock GC STI setup.

There was a thread recently on an english forum that they managed to safely pull 396hp (295kw) out of a td05 big 16g with supporting mods so they are a pretty potent turbo even in that form, the 18 and 20g are likely to be under less stress at that power tho.

22g seems to be some other wheel Steve M uses, maybe a garrett of some sort that is a bit bigger than a 20g?

Dyno numbers are just that, over time with averaged results you will find the 16g will do "about" 340-360hp, 18g 360-390ish and the 20g 360-420ish depending on setup of cause.

You will start finding limits of the td05 turbine at some point with the 20g or bigger, some have found good results using the 18g - not lost alot of power over the 20g but gaind better spool.

The best i have heard of with a td05 20g is 440hp at the engine on a 2L but that was with some other fuel, maybe lots of meth.

I believe Steve offer's a 22g TD06 comp housing upgrade, a few of them have popped up here and OZ.

Can't say what the wheel is based on though, he is certainly doing good work with later gen VF series turbos.

311kw@wheels with IHI VF36.

[Guest]

Wasn't that 311kw with nos ? and a RX6R wheel ?

Yes there has been some good results but there is not alot of vf36 left.

And race fuel!

Anything's possible. Probably 240 without all that

[BC5RA]

Read it.

311kw without NOS.

The Steve M one ive been offered is a td05/td06 mix with a 22g wheel that your talking about. You think it would be a good upgrade? I have all the mods to support it and i would say the fueling is the only hold back i have. I would need bigger injectors and a new pump prob

[BC5RA]

More info on your set-up would be good.

You wont go too far wrong with one of steve's turbos, just make sure it is one of his and not some china rip off.

anit tdo5h 16g good for 250kw atw with right fuel set up?

[Guest]

230kw sounds more likely.

250kw would be abit much for the average car.
