610 Turbo

[JonKing]

I have heard that the turbo on the 610 '05 has a larger exhaust housing than previous years. Does anybody know the spec's on this turbo?

 

[johncameron]

I'd like to know too! Anybody?

2003-04 turbos have a 9cm turbine housing and a 3. 5" approx exhaust downpipe outlet. The compressor wheel is around 56-58mm.

The 04. 5-present have a 9cm turbine housing also and a 4" exhaust downpipe outlet.

The 04. 5-present turbo has a larger 12cm compressor housing along with a 62mm compressor wheel.

Williams,

Thanks for the info. What are the spec's on your Phat Shaft 66 and how does it spool?

 

[jwilliams3]

66mm compressor wheel and a 70mm+ turbine wheel, 12cm +/- compressor housing, 14/15cm turbine housing, dual valute wastegated (yes this thing will move the air!).



The turbo spools very well for its size. I run a 6 speed. I dont know how it would run in an Automatic, but the guys that make it run auto's and seem to have really good luck with them!



The Turbo has impressed me and several other that run it on this site.

Have you dyno'ed with that IISPS66 yet?

 

[jwilliams3]

Not yet.

Probably dyno up at Scheids Event.

 

[OT-OF-HERE!!]

04. 5 and 05 turbos I've been told are the HY35W. They are 60MM. If that's wrong then I've been misinformed. Hope that helps. Both Piers and HTT gave me that info, fyi.

 

[lmills]

I have always heard 62 mm also.

 

[jwilliams3]

HE351 is the model number, 62mm compressor wheel. Same size as the B104 and HTB2's.

I could always be off by a mm or 2! :-laf :-laf

 

[lmills]

I believe the first time I read 62 mm was in one of the TDR magazines

 

[JonKing]

What would the ratio be on the stock turbo at 50 psi? Am I going to send it thru the hood at this pressure?

 

[speedyjdl]

I've heard the new turbos are running a 10cm exhaust housing, but i don't know anything about the turbine sizes or compressor housing size.

sooner or late yes. most likely sooner.

RE: Stock Turbos 03-05

These turbos DO NOT like to be turned up much on fuel. The small turbine housing sizes along with small turbine shaft sizes, overdrives these turbos. We see a lot of these stock turbos fail with modest fuel increases. When we build our Phat shaft turbos we use only extreme duty bearing. These bearings help keep the turbine wheel, shaft and comp. wheel centered in the turbo. The large shaft size also helps with shaft flex, at over 50psi pressures. The bearings are damn expensive but worth every penny. Third gen head gaskets will hold 50 plus psi. But will fail also at some point. Some guys get away with a lot and some don't. Thanks I hope this helps.
