Hey guys, just got my '13 STI and loving it, especially running an intake, TBE and protune. The only thing that bothers me is coming from an '11 WRX it seems like I have to get much higher in the RPMs to see any power. I know it's to be expected with a bigger turbo. But this is troubling because a lot of my driving is stop and go city driving, and with my SPT exhaust it just draws a LOT of attention when I have to rev above 4000 to get any power. I liked that the WRX had plenty of power in the low end (after I went stg 2), and was expecting the same with the STI but I'm just not seeing it. Would be nice to not have to downshift two gears to get the car off it's a$$ and moving, ya know?
I've done a lot of reading the last few weeks and it seems a lot of the info out there on this issue is grossly outdated, so I was hoping to start a new drivabiity thread to share new ideas and experiences with the recent (08-13) model years.
The one thing I've read a million times is "Get rid of your catted uppipe!" Well, I don't have a catted uppipe so that's not very helpful. Is there still any noticeable change in spool for the non-catted years? I'd bet it's far less dramatic.
Would headers help noticeably? I don't want to spend the $1000 if I'm not even going to notice the difference.
A shortblock, turbo, etc are not out of the question if you have any insights on those, but they won't be happening any time soon...and I like power, so I don't want to downgrade to a smaller turbo. Maybe one with faster spool that can still handle high boost efficiently, if that even exists.
I've also thought about e85, but heard from a few people that with those torque levels the OEM clutch goes pretty quick. Anyone have any experience with running e85 on the later model STIs? While I wouldn't mind the additional power, I'm more concerned with shifting the power band to the left a little or leveling it out a bit than I am with just getting higher peak numbers.
Looking for more area under the curve. Thanks.
