Spool reaction time is about 500 rpm difference. At least thats according to d-sport magazine. I have an article comparing the two. My shop however does all their turbo set ups with *** ball bearing because im told of longetivity.

i ahave a ball bearing and it seems to spool hella fast. plus in the case of a turbo rebuild, ball bearings are much easier to replace. according to turbonetics.

I don't know if this is true or not but I've heard that phoenix turbos micro-polish the inner shaft which will spool just like a ball bearing turbo. Is that true?

More HT hearsay but, i thought that to rebuild a bb turbo, you need to replace the whole center section. Once the bbs are out, the dont go back in

all i know is i bought 4 Journal bearing turbos last year.
i just bought a 35R and i am so glad i wont buy another turbo for a long time
definetley worth the money

Re: (streetsold6teeny8)
Time to boost will be reduced but so will throttle response when above the boost threshold RPM, don't just look at one angle. You end up with a turbo that is more responsive in *every* respect.

yes
the better spool time is only like 20% of what makes a ball bearing turbo awesome.
trust me i run both and i would NEVER EVER run a non ball bearing turbo EVER. it's just that much better yes.
i've had t3, t3/t4, and gt28rs w/ .82 ar
the gt28rs OWNS!

ATPturbo.com I have purchased two turbos from them (GT2871R & GT4088R), and exceptionally good customer service and great shipping/packaging. I am all the way up in Canada too.

You can't judge the improvement of spool time like that. It is a percentage, so it could only be a percentage improvement over another turbo of another size in another engine. A larger turbo on a small engine would probably see a greater improvement than a smaller turbo when it comes to BB vs non-BB.

Soo the rest of you guys are telling me that is the same Shyt only 500 RPM's That it will Spool Faster On A T3/T3 </TD></TR></TABLE>
Yes, in some cases only 300rpm

Re: Ballbearing Vs. Non Ballbearing? (streetsold6teeny8)
Spooling quicker isnt the only benefit of a dual ball bearing configuration. Posted by Jeff Evan's recently.
<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by "boosted hybrid" »</TD></TR><TR><TD CLASS="quote">The purpose of a ball bearing CHRA is not for quicker spool in a semi steady state condition such as the dyno. "Semi steady state" meaning having the engine accelerate over a fixed time and letting the turbo reach a given pressure. The biggest difference between a standard bushing turbo and a ball bearing turbo is the transient response on the street. It doesn't drop out of boost as quickly between shifts. The time for the wheel to build momentum to give positive pressure is much less. The dyno does not show the response and driveability of this turbo on the street. The particular car you referenced (making 610whp) had virtually no response and would drop out of boost so quickly between shifts. If you were to datalog a timed acceleration run where multiple gear shifts were made, you could overlay rpm vs. pressure plot and see how much quicker the boost builds on each gear change.</TD></TR></TABLE>

the major benifit isn't the quicker spool.
a good setup with bb turbo is just a hell of a lot more fun. you can throttle the boost very well. the response difference is amazing
