I was wondering how many of you had a To4 hybrid with a stock hot side on your cars? And when do you spool up? How hard is it to keep the boost down?

I have an S5 TO4 hybrid with a stock hot side on my s4 and so far I dont get any boost untill about 5K. So I was just wondering what boost curve people with a similiar turbo setups have. Thanx for the help!

 

Something way wrong... who did the Turbo? I have a guess.. but I would like to know.

Also is the turbine wheel clipped?

Turbo was just rebuilt! The rebuilder said there was a crack on the turbine housing by the wasgate and it would leak so I wouldn't build boost as quickly. But then Bryan at BNR said it was good. JUst a hairline crack no big deal. He said it was a really good turbo and rebuilt well. ( I had sent it to him to replace the housing but he said no need to)

What numbers do you do?
no turbines wheels are clipped. Hot-side is stock, and cold side is like 60-1 something I dunno. What ever goes into a ported TO4 housing

Oh the wastgate is ported to! Thanx!

 

What kind of clutch are you running with that turbo? I will be running with a simular setup. My engine is street ported, will have turbo-back exhuast, and microtech... so would that be good or too much for this clutch : http://cgi.ebay.com/ebaymotors/ws/eB...tem=2446545683

 

Clutch? Why don't you start a thread? I wouldn't be able to tell you, because my turbo isn't working right yet. So, can't help you there but any after market clutch should do it. I think there's a thread about clutches. Look there.

 

At this point I will leave someone else to give you advice ... I might get pissed and say somthing I don't want to. No offence to you, trust me.

Spend a few more bucks and you can get the ACT kit that includes a better (not stock) disk. In all about 20 dollars to be exact.
