Precision 5857e CEA with Garrett .63ex housing

[bison]

Zero run time since freshening. Garrett .63ex for improved spoolup. This is a fast spooling setup with the high flowing cea compressor wheel. $725. $675 if you send in a stock ex housing.

How much more will this exhaust flow over a TE44 with precision .63 ex housing?

Idk exactly but this is an 57f1 turbine with 10 blades. The Garrett housing is gtg up to about 60lbs/min with the right wheel. If I had to guess this turbo would support at least 58lbs/min worth of mass flow and the cea wheel won't die off at higher pressure ratios for those guys that have stock heads and cam and need to run high pressure ratios to make any decent power.

That's me. I can get 28psi right when I lock the TC but other than that, I have a hard time getting it to 25psi. I have very minor port matching on the intake and heads and a 208/208 flat tapp but that's it. I know the TE44 is as good as done around 120mph in a full weight car. What gains over that could be had with this turbo?

 

[bison]

If you could get the 58lbs/min out of it it will probably trap in the 125-126mph range if the converter slip is low enough. idk where the 58cea starts making a lot of heat but with your combo I don't see it laying down till boost is over 30psi and over 5300rpm.

Arent those the same size turbine? In fact arent the compressors the same size too

Same as?

TE44 and the 5857 use the same size compressor wheel but the 5857 is the new CEA wheel. The turbines are different though. The te44 uses the old small wheel and becomes a restriction around 120mph leaving room for compressor performance but the hotside on the 5857 should flow more than a TE44.

what stall is recommend with this turbo?

I would want at least 2400@0 with a 10". With 2600@0 or more it would be a really fast spooling setup. It will make more power than any of the common cheap converter can couple if it's run for all it's worth.

OK. I thought the 57 trim would be the same as the T3 turbine on the TE44

Maybe it is, but I thought the TE44 turbine was a lot smaller as in 31 vs 57 mm?

The 57f1 flows more than a stage 3. How
much more is not published. They are basically
copies of the garrett gt turbines As far as design. Stage 3 is not 31 mm. The 2 wheels share nothing as far as design. They are totally different.

Bison, I have a 4431 on my car now. Would the Garrett housing spool faster than what it has now? Will my turbo or yours make more power at say 25 psi?

 

[bison]

It woudl depend on what your engine can support. The 5857 will flow more than the 4431 will without a doubt. Upon further reading it looks like a few import racers have achieved around 60lbs/min out of the 5857. That would net 10.70-10.80 power in a turbo regal with a good hook. The engine has to be able to flow it. At 25psi there would be some gain but from there on it would walk away till the compressor is out of breath. From about 50lbs/min up the 5857 should crush a 4431. If your trapping 116-117mph@25psi and looking for 120mph this turbo will get it done though it might take a couple more psi to do it. This turbo with the Garrett .63 should spool as fast if yours has a Precision .63 on it. If you had cleaned up bowls and a good valve job this turbo would really shine at 25psi.
