Default 12 Sec 1/4 Mile Stock Turbo/Fuel Record

The mystical 13.00 second barrier has been broken. I did this tonight at Atco raceway.

R/T ... .847
60' ... 1.843
330 ... 5.362
1/8 ... 8.297
MPH ... 86.29
990 ... 10.841
1/4 ... 12.981
MPH ... 107.00

Before going to the track I removed the spare and all mats. Took everything out of the car but the seets and my laptop.

My first attemp went pretty badly so we won't talk about 14s I hit the rev limiter and messed up my shift to 4th gear (got me 2nd instead). My second attempt was much nicer and got me 13.131.

I had delta dash plugged in and running during the 1st two runs. Between my first and second run I upped my boost a little 14.5 to 16 psi. I normally can't run higher then this without getting knock correction. Using Unleaded racing gas, I was able to up my boost.

After the second run I checked the Delta Dash run and my timing was still good without any knock correction. So I upped my boost a little bit more. I'm not sure what it is but I think it went to 17.5-18 psi in 3rd at around 5000 rpm (only got to see it quickly during the run).

For my 3rd run a guy I hooked up with suggested we pull my backseet out. He had tools and helped me (pretty easy to do). He also suggested we take off the muffler. We let the car sit for a while until it cooled enough to pull it off. I wasn't sure about pulling the muffler off the car because it was "muffled car night". He said f*ck it and pointed to a couple of other cars without them so I agreed. I also removed the air filter for the 3rd run. I also put what was left of the 2 bags of ice I had brought (still in trunk getting free rides on the intercooler. I just shoved the ice in the hood scoop after removing from the bag.

I also adjusted the my tire pressure. I let a little out before the 3rd race and the pressure hot was 35 (f) and 32 (r).

Since I really wanted to break into 12s I did a bad thing. I let the cluth out very quickly, I dropped the clutch at 3500 rpm instead of slipping it at 3800 as usual. I know dropping it is bad but atleast it was only 3500 rpm.
Here is the shift points I used:

Drop Clutch Launch 3500 RPM
2nd Gear Shift @ 7000 RPM
3rd Gear Shift @ 6400 RPM
4th Gear Shift at 6400 RPM

List of Mod:
Turbo XS Stage 2 system with 94 octane map. The components of this system can be looked up at www.turboxs.com.

Other Mods:
TurboXS High Performance MBC
ATR uppipe
GFB pulley kit
Colder NGK Spark Plugs
Cat-less Mid Pipe
Samco IC Hose kit
Grounding Mod
Silencer Removal
Filter Removed from Airbox (racing only)
Knife Back & Porting of Throttle Body
Cleaned up (dremel) manifold & turbo inlet
IC elbow cleanup with Dremel
STI Short Shifter (edited 6/8)
"Special Gas"

The car has no N20. It has stock turbo (not FP), stock fuel system including injectors. Stock 16" Rims and tires.

Next goals:
12.75 with VF30 Turbo (being shipped),
12.50 with upgraded injectors
11.99 with N20

Sweet!! Thats a great time and a high trap speed too! It's interesting that you were shifting at 6,400rpms for 3rd and 4th gear, how come? Was the boost dropping alot after that?

I've been doing a lot of homework with a device called the AP-22 Performance Meter. It's kind of like a G-Tech but on steroids. It has a comm port so you can download all your info into the computer. I then created a horse power plot similar to a dyno plot only it's real world with wind resistance and all.

Then based on my hp plots and knowing how much RPMs are lost at each shift point I calculated out the optimal shift points. They are actually:
1st to 2nd: 7000
2nd to 3rd: 6460
3rd to 4th: 6440

I don't know about you but I can't shift at 6460 so I rounded it down knowing the RPM will rise slightly if I shoot for slightly less then 6400.

If I was going all out and needed a 4th to 5th shift it would be at 6300 RPM.

I very analytical and like to figure out every little detail.

Nice time on a stock induction system.

Pulling the air filter would not be my choice, but sounds like you avoided any FOD (Foreign Object Damage for you non-aircraft types)


Your ideal shift points match up very well with the shift points recommended some time back by a powertrain engineer on one of the threads where they got into that in detail.

good job!!! Those trap speeds (1/8 and 1/4) are insane!

I thought with my 1.83X sixty foots that my traps were pretty damn impressive... but 107!! Wow....

I should have been there myself (12.99X), but my new clutch proved more of a challenge to launch properly than I figured, oh well.

I am gonna go tonight... not sure if I'll run or not, but if I do perhaps I'll be joining you.... got less than a tenth to go.....

Wow...

I haven't seen 107's with anything less than N2O or a big turbo...

Amazing how you did it with a 1.84 60ft time. I'm cutting 1.75's with traps that never go over 101-102MPH... somehow your getting 6MPH higher than me... How much weight do you think you dumped. I also took out my spare tire but not back seat.

I would estimate your making what? 250-260 to the wheels?

We'll have to meet up so I can check for N2O ports hidden under your intercooler great run!

For comparison sakes:

Code:
	Me	You	Diff
R/T	1.218	0.847	0.371
60'	1.836	1.843	-0.007
330'	5.364	5.362	0.002
1/8	8.340	8.297	0.043
1/8 mph	83.08	86.29	-3.210
	1000ft	990ft	
	10.907	10.841	0.066
1/4	13.097	12.981	0.116
1/4 mph	103.11	107.0	-3.890
Also to note... when I ran at Atco, the 990ft mark was generally about 0.05- 0.10 seconds faster than Cecil's 1000ft mark.

i'd be more impressed with a 12 second stock turbo that has full interior w/air filter..and a muffler than this.

this is really a race only setup..you're making good power to hit 107 though

I have never been to the track but might be going soon? Who else has shifted at or around these shift points? This might be the reason for the great trap speed if the motor was in the sweet spot longer. Also the reduced weight definetely helped get there.

Good Run.

Great Numbers!!!!

Here in PR I had run a 13.9 @96 with just a K&N drop in and an EVC set at 17psi, but the big trick I think that helped me was the bag of ice on the IC because I went the other that and something might be wrong with 2 of the cylynders (Getting huge ammount of blow-by but nothing else wrong) that with all my mods (Stage 2 plus pulleys, samco IC hoses, silencer mod, Completly cat-less) and did same times and MPH but no ice bag on IC. Humidity was arround 80-90%

Hmm,
has anyone else felt something is funny that he and Doug are both running freak times at the same track?

I don't hate either, if those times are accurate, then mad props. I just don't see someone with the same mods trapping 6mph higher.

Carlo,
What was the weight of your car with the backseat and spare removed?

Mine weigh in at 2970lbs without the spare tire, jack and fuel tank on E.

that's pretty light. Mine is always 3040 no matter how low the gas is (never totally on E). is yours wingless?

I'd say any given wrx could have a 6mph difference in trap speeds on different days. The stock ecu is very fickle.

True but we have never seen a trap even close to this high without an aftermarket turbo or N20.. not even close. My traps and Dougs traps are VERY consistant. Always between 100-102.

yup, and NO ONE gains/loses 6mph day to day. That's rediculous. I go +/-2mph but that's it.

But were you running race gas? At least in my car, the stock ecu *loves* high octane...

Power mods on the 13.097 run:

Vishnu Uppipe
Vishnu Unichip
Vishnu Crank Pulley
NGK 7 sparkplugs
(Stage 0)
SBC i-D EBC (16psi)
Removed Muffler
95ish Octane

Other Stuff on the 13.097 run:

STi Shifter Linkage
STi Tranny Mount
STi based intercooler sprayer (didnt really use)
Full Interior
1/4 tank of gas
225lbs driver, me

Currently have added the following:

K&N Panel Filter
Samco Hose
BPM Lightened Flywheel
STi Type RA Clutch
Replaced Muffler with bent pipe
w/tip

Soon to be added:

STi Engine Mounts

I think I will run tonight... but I have pre-turbo exhaust leak, so spool time has been hurting lately. I have all new gaskets ready to put on... just gotta get around to it. Hopefuly I will do alright... also, on the 13.097, I was running a 100% vent GFB BOV and my clutch was about done... slipping pretty good. I have been swtiching back and forth with stock/GFB BOV to see if it makes a big difference in 1/4 time... so far I have not noticed a difference, although my fastest time was with the GFB BOV.....

Yes... I've run race gas with my standard and even a remapped Unichip... I didn't pick up much.

Where are you going Doug?
