I am new to this site and this is my first post.
I just did my first mod: stillen intake with Z tube and 5/6 motordyne spacers.

I like the high end power but is there a way to add more low end power improvement for someone like me without going FI?

BTW, I have 05sedan with AT

 

The 5/16 spacer is one of the best mods to get a little more tq. The only other option to get a lot more is NOS.

 

Probably a timing advance of some sort. ie.. reflash / tune with emange Ultimate / Utec etc...

 

you can get some lighter forged wheels as starter. It wont give you more low end torque per se, but you'll feel a big difference in launch and acceleration.

 

+1

If you keep your wheel size down to 17-18" and get some forged wheels you can shave off some unsprung weight which will help in many areas.

 

grounding kit, reflash ur ecu by technosquare to get 100% wot, some headers, lighter flywheel will make u accelerate faster.

 

You sure about that flywheel thing?

j/k.........

 

lightweight UR crank pulley

 

Get a carbon fiber crank shaft! Oh, be sure to have lots of money before you try it.

 

^^^$1100 and car down for 2 weeks might be next on my list... undecided for now...

To the OP - believe it or not a there is a particular TB spacer that has added low-mid TRQ on several cars including mine... there is still beta testing going on and I'm not going to respond to a flame war... I'm not going to tier my fingers with justifications either... take it for what it's worth. I have it on my car and it is staying.

Also, 3.7 FD adds a huge fun factor, just had mine installed yesterday and lovin' it more every time I drive the car.

 

Sorry....but whats a 3.7 FD?

 

final drive gear ratio... it's actually 3.692. It's the ring & pinion gear set. If you are MT OEM is 3.5, AT is 3.3... many 3.3 have gone to 3.5 and 3.5 have gone to 3.9

3.9 is an after market gear - 3.7 and 3.5 are OEM.

 

For nice low end torque gains you may want to consider high flow cats (i.e. Crawford) and a UTEC. I went with that combo before I went FI. I specifically asked altered atmosphere to tune the UTEC for more low end torque. Saw some nice gains, ~17 ft-lbs at two points in particular. Top end gains were nothing special, but there were some nice deltas between the baseline and post UTEC & HFC torque curves in low to mid range. I have the dyno printout if you're interested. I also had an intake, z-tube, and plenum spacer. The HFCs will add a few ft-lbs (freeing things up on the exhaust side) and the UTEC will bring your existing breather mods to life.

 

+1... indeed HFC add trq... I have Crawford as well... when added I had TS flash for Stillen CAI, Exhaust and 1/2" spacer (TS uses Crawford plenum specs for that)... the cats allowed so much air flow that I was running lean and the car was a slug! After tuning the a/f ratio I had noticeable trq! Posts are out here somewhere...

 

Here's the dyno printout, sorry about the quality. Baseline was done with a pop-charger, z-tube, and 5/16" plenum spacer. Adding the UTEC and HFCs had the most notable difference between 3000-4000 RPM. There are two spikes in particular where I gained about 18 ft-lbs. And I could definitely feel it on the butt dyno. I think the secret here was with the tune though, note that the top-end numbers are not that impressive (before: 228.43 hp, 206.71 ft-lbs, after: 232.91 hp, 211.50 ft-lbs). I specifically asked for this though, and they delivered.
