Anybody able to get their stock ct26 to spool quicker than 2500 rpmish? I can't remember what my stock spool was like with no exhaust mods or intake mod, but I know it wasn't much worse. Since then, all that I can think of that really affects it was the 3in exhaust and the removal of my airbox to a k&n with adapter onto the maf. Now I also have a spearco intercooler and 2.5 inch lines. Anybody else get better spool times with the stocker? Its in good shape, but I realize that the ct26 isn't that great. I am still thinking my car is a little doggy until boost after the build, but I think I am imaginaing things. Any way, just looking to get some ideas on what the spool time is stock and what it should be about after exhaust and intake.
I'm not even sure what "Poochy" means. But I'm very much in the same camp as funky_monkey58. Turbo's are derived off exhaust gas, what could you possibly expect? I mean 2500rpm? If you want instantaneous boost levels lose the 7M and find something with a supercharger.

Who came up with this 500px wide BS?
well your car must be kind of poochy then. But I guess that is the price you pay for more top end.
I would not really call my car "poochy" considering anything above 20 mph, I can be in the correct rpm range in a second or less and have full neck snapping boost.
Well thats good. I guess what I am trying to say is I would rather go with a turbo that may be a tad smaller, and with a clipped wheel. But then again, I don't plan on going over 15 pounds. I want my spool to be fairly reasonable.
Well, all the twin entry does is add a little more flow to the waste gate. I was thinking about it, but its alot of work just to put the same turbo back on.
Well, okay, I am not trying to be a prick here, but under your logic, more exhaust gases being diverted away and out from the exhaust turbine would somehow create more force and spin? The dual exit* exhaust housing only allows you to achieve *desired* boost more efficiently, not faster spool in general. If there was no waste gate, and the engine was spewing plenty of exhaust gas, well then, the exhaust turbine would probably spin up pretty fast, but then of course it would continue spooling until the turbo blew. But with the dual exit, the actuator/boost controller has efficient control over holding desired boost levels with more exit area.
Allows gas to escape more efficiently when opened, holds boost more accurately. This port allows exhaust gas to bypass, not enter the exhaust wheel so that it slows spooling.
The twin entry turbo was designed for a 4 cylinder, so it will spool faster, but it will choke on the top end. LOL who am I kidding the CT26 chokes on the top end anyway!
