Which turbo has the quickest spool-up time? I am trying to decide still. HRC or star. I hope to be boosting by next year. I want to get the body mods first. But I have that money saved already. I jus wanna know which spools up faster? I like the HRC super 16g, but I was thinking, would the star bb turbo spool up at lower RPM's?

From what I understand, the Super 16G from Hahn spools a tad sooner. Hahn hits full boost around 2700-3000 while the Star is in the 3000-3500 range. Sound correct guys? (of course, this also depends on other things, like amount of boost, backpressure after turbo, etc.)
'99 Eclipse GS yeah, I know...they called me and said "they don't make those is gunmetal 5 lug" grrrrrrr. http://www.rokitlabs.com

I have a T3/T4 Ball Bearing and I get full boost at about 2,600rpms. And Thats without an Exhaust!! Ya, Don't laugh, I still have the stock exhaust cause I am VERY picky with the sound of my Exhaust:-)
I just tested my 0-62mph time and I got 5.9 sec at 4psi!! And I don't consider myself that good of a drag racer. yet.
I GOT 3rd AT MY FIRST SHOW!!

Alot of that is due to the ball bearing option. In addition to a drastic decrease in spool-up time, a ball bearing turbo can withstand 50 times the loads of a typical turbo armed with a conventional thrust bearing.

...that they would include ball bearing options with thier turbos. They're expensive. If you were going to get a ball bearing turbo from HRC, i'd get the BB Super20g. Why spend the xtra money to get ball bearing if you're not going to go all out with it ?

The theoretical advantage of a BB S16G is some mad spoolup and low end, but I agree it would be more beneficial ona larger turbo. The BB is not actually THAT MUCH more really. It is going to cost me about $200 more or so to upgrade to a BB S20G over the standard S20G. The BB option will not rreally offer any improvements in power, just in theoretical spool time, which remains to be seen. I will try it to see what happens and I will have a S20G non BB to compare too, but I am putting this upgrade off until I have all my other new mods worked out and finished which means I will not have it until after the shootout. I hope to do well on the S16G anyway.
