EDIT: I left off the word "turbo" from the title.. oops


Freshly rebuilt Turbonetics t3/to4b s-trim w/ .63 a/r stg 1 clipped.
First off, I have a few questions..

1.) What's the advantage (or reason) for having a clipped wheel?
2.) What's the s-trim?

Now on with the pics:








What does this # mean?!?!

 

the clipped wheel is the cheap way to basically increase your turbine size, it lets the exhaust side flow better with the expense of spool time

 

the s trim refers to your compressor..
here is a map http://www.majesticturbo.com/20330.html
it flows 37 lbs/min

 

So would this turbo be as good or better as a t3t04e?

 

How do I figure out how much air my motor uses/needs at 8100rpms?

 

I just plotted my #'s using BlueSi2k's turbo sizing utility, and it looks like this is the perfect turbo for me.

Pressure Ratio: 1.578
Air Flow: 21.5lbs/min (at 7psi)

im famous!!

 

Infamous is more like it...

Hey, why does your calculator get a runtime error (Type Mismatch) when I raid the underhood air temp?

 

oooohhhh cool, where can i find that utility. looks pretty damn cool, and helpful
Thanks

 

BlueSi2k
there are some bugs in the utility
(changing the temperatures causes 'Run-time error 13': Type mismatch')
other than that its pretty good
he still got a good grade on that project anyway

 

here's mine...just got it the other day from cheapturbo.com

sorry about the error...i made that quick i dont know whats up w/ it. Wasn't for a class or anything, just made it for the h-t guys. Maybe when i get time ill make one w/ built in compressor maps that plots for you, that would be cool.

 

It would be even cooler if I could raise the air temp... since it's consistantly hotter than 85 here in sunny Florida (bleh )

 

thats a big bish<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by REMUS 13 &raquo;</TD></TR><TR><TD CLASS="quote">here's mine...just got it the other day from cheapturbo.com

why did u get an on center housing? fitment issues??

 

actualy i know remus, i personally saw this turbo, the cold side says .70 not .60 , the a/r is 58 tho, kinda funny cause my t4 section from my t3t4 looks bigger

 

It is .70...I just hit the 6 instead of the 7 by mistake I guess. Sorry folks.

 

so if its a 60-1 why is the wheel a 6 blade, and if its a hifi housing why is it a .70 a/r?

A 60-1 is a 7 bladed wheel and a hifi is a t04e .60 a/r housing. Maybe i am missing something or looking at something incorrectly

 

dunno but he told cheap turbo he wanted a to4b 60-1 hifi, and it says .70 on the cold side, 58 hot
