Default For tC owners looking to hit 14s with an N/A setup

Ok, so I was looking around tonight and I saw several posts where N/A guys are in the 15.4 to 15.2 range with their setups. First I want to say I commend you guys for striving to reach the 14s with your setups, guys like Aarontrini and SenseiTurtle look like they are close. I know there are others as well, I just dont want to write a novel here, hehe.

So, for those of you that are close, or others that plan to get there, here are my questions. What power mods do you guys currently have and what suspension setups seem to be working best for this purpose? Do you have any ONE particular mod that you guys think may have made the biggest contribution to your goal?

Please chime in

N2O. Aside from that....

Lighten the car up signifigantly... tune A/F... and get the intake and exhaust breathing well and you'll get close like they have... No one's done too much MAJOR engine work yet... so it's all bolt-ons, plus as much tuning as you can do with camcon or Apexi...

I know you might find this hard to believe... but it is ALL down to driving.


But really... the 15.4 is with JUST a homemade intake (a hacked airbox) and taking out the back seats and everything that looked like it weighed over 5lbs.


Lowering tire pressures helps, but I didn't. I just got a very good launch and drove it like I stole it. Partially might be my shifting, as I never let the throttle go below 80%. Every time the clutch grabs, it pushes the car forward while slipping ever so slightly.

It was also a colder, drier night at about 30 feet above sea level. About 50 degrees and around 10% humidity.

Strive for that 2.2 60-foot, and keep practicing the shifting until you're sure every ounce of forward energy's being harnessed. Tiny chirps from the tires = perfection, but peeling out halfway down the track loses lots of time. Try keeping the throttle depressed while shifting, aiming for smoothness.


It'll happen... Mods are no good unless you practice and know how to use them. Hopefully, you'll have me on video hitting the 14's within a few months.

I know it sounds like just a freak run, but I hit 15.5 twice before hitting 15.4

It's all down to the 60-foot.

90% is knowing how to drive i have only been driving stick for 1 year this is my first car with a manual tranny but what i did is picked up a apexi rsm and practiced launches at almost every stop sign and light on my 1 hours drive on country roads to work that was for about 1 year 5 days a week. other then that i had a custom intake we made with some 2.5 inch pipe (the tc doesnt need 3" like every one else is making them infact the injen drops down to a 2.5 in the middle so its useless for the rest to be 3") also i had just sold my injen and couldnt find my stock exhaust so i was running with out a axle back portion on my exhuast and a trd coils and sway witch do help with the launch a bit the fact that there a little more stiff helps prevent weight transfer and i also had them align my tc to have the largest contact patch on the tires possible while the wheels are straight not the best for handeling but great for straight line traction. i had also gone to a larger tire a 225/45/17 rather then the stock 215/45/17 slightly bigger side walls and at the time i had mitchmatched tires bfg geforce in the rear real stiff sidewalls and in the front cheap ___ berums witch have a soft sidewall so i droped the tire pressure on them to 12 psi i belive and that help alot with traction i was able to launch at 3k rpms with no sliping of the tires and that is what got me to 15.2 i now have alot more mods on and coming in the mail so without removing any thing from the car no weight reduction at all i should be able to hit a 14.9

yeah turbo trix does good work. So I've heard (from a very reputable source)

Best way to improve 1/4 et's is most likely some nice racing slicks or just bad ___ rubber.

INSANELY cheap if they do... I'd bet it's just the headwork... install and removal must be extra... That's super cheap for all the work that would be involved in removal/reinstall of a head on our car... I would have done the ZPI head, but the labor at any local shop was WAY too expensive and it's too much for a normal tuner to undertake.

Has anyone hit 14.9?

I'm sitting here clenching my teeth trying to will a tC into the 14's naturally aspirated. Or is my mind just not strong enough?

Ok, everyone always rags on the moron guy with a beat up CRX who throws out everything in his car and drills holes in the floor to lighten the car - why can't one of these so called ricer boys with a tC do the same with full bolt-ons and just eek into that last two or three tenths of a second?

If you want on topic, the topic has already been answered by senseiturtle - it's mainly down to technique... but DAMN, it's so close.. Oh well, maybe next month.

BTW, why should it matter who buys what for whom? Attitude should be what matters.

WDS, heh, sorry, I don't think I brought it back on topic any further.. just.. 15.2 has been hit.. just 0.3 more seconds, dammit.

yes back to the topic. ZPI has some all-motor pistons that I'd look into in the future. My goal is hitting mid 14s with a full interior with the expection of the spare and all that good stuff in the trunk. ZPI also offers a head package for $550 after your deposit is returned.
Maybe we can tap into 15 flat or high 14s with I/H/E <<(full exhaust) pullies, lightweight flywheel, camcom, and some better tires. Bolt-ons are good but in the end its compression that is the key of N/A horsepower.
