Ok so ended up picking up a larger turbo than planned but I wanted to have room to grow.

This is the description:

60-1 master power with two backhousings .48 t3 and .63 t3. Specs: model #810039-048, a/r .70 air inlet 101.7mm air outlet 64.0mm, ind wheel 60.5mm exd wheel 84.0mm 52trim 6 blade. Exh t3 5bolt .68 and .48 included, ind wheel 56.00mm exd wheel 61.5 83trim 10 blade. turbo is rated for 600hp +.

I'd be running the .48 turbine housing. From my research I foudn its a stage 3 wheel. The trim of the compressor is 52 and the trim on the turbine is 83.

And lastly, will the turbo be able to make about 400-420whp on a 9.2:1 81.5mm b16 without being too laggy?

 

Here is a chart I found for the .48 housing im going to use. its the one outlined in the red box.

 

its going to be regardless. The compressor housing with the turbine wheel is rather a mismatch, but it will take over 15-18psi to get over 430whp w/ any efficiency.

good luck.

 

how is it mismatched? a t3to4e comes with a stage 3 wheel much like this turbo and comes with a .63 compressor housing and a .48 turbine housing (it is also offered with larger turbine housings obviously). is a .70 really that much bigger?

 

Well from what I can find this turbo is a tad bit larger than a t3t04e 57 trim if I use the .48 housing.

If someone else can back that up, or even correct me that would be awesome.

 

I think The Shodan is saying that a stage 3 .48 hotside is small and restrictive compared to the s-cover compressor its mated too. probably making it less effecient.

 

Yeah I'm aware its rather small, but I don't want to have a ton of lag.

Would the .63 housing spool by 5000rpm?

 

A 57 trim is a 50lb/min compressor wheel compared to a 60-1 61lb/min wheel in a larger cover. A smaller housing will not solve your issues in the way you think they will.

Your question is whether or not you'll reach maximum pressure on a b16 by 5000 rpms. The answer is yes, under 20psi. After that point, no.

Sorry. this turbo is mismatched for its power potential and use (at least from my experience)

 

After what point?

 

AFTER 20 PSI... Am I not being clear? please let me know.

 

Thanks!
