Default What modifications for 12 sec. 1/4 mile?

I just was interested in what modifications the big boys were running that are in the 12 sec club. I figure I might as well pattern my car after the guys with the experience.

I highly doubt that it is RiftsWRX with a stock TD04. I have not seen this either.

it isn't yet but the numbers are... 239+HP and 250ftlbs.... the + is another 10 with the cat back. I've seen subies with less than that run 12's.

Shiv's stage 1 is supposed to make near, real near the 300fwhp. Maybe more, their are guys on here running mid to low 13's with a stage 0 and an EBC. So I could easily see the stage 1 running into the high 12's stock turbo, fuel sys, IC, i'd have to say that for the money that is a very nice way to go. Besides I don't know of many sompanies that are more concerned with their customers, and haveing a great product even if that means taking your time.

I will be vishnuing my WRX all the way.

^ true dat (referring to jmott, I just lagged on typing)

From what I've seen, people have run very near 12s on a stock turbo with only intake, exhaust, some fueling, and tuning.
I would think it would be easily possible with the following (I'm armchair dragging here, bear with me.)

up-pipe + turbo back
Samco IC hoses
larger injectors
fuel pump
<Insert larger than stock turbo here>
Tuning (Unichip or otherwise)

I don't think it matters what turbo, from FP/vf24 low lag type to 1820 high power type. You could get DEEPER into 12s with larger turbos, FMIC or upgraded TMIC, etc... but I think the above is all that would be necessary to guarantee 12s given a decent driver.

People have gotten so close to 12s on the stock turbo that I imagine you could break into the 12s on the stock turbo if you really tried.

I really think that a Vishnu stage one will push some people into the high 12's, especially with a cat back. Even if you don't take the dyno numbers literally, you can still use them as a comparison. The stage zero increases horsepower by 30, and that took over a full second off of many peoples 1/4 times. Do you think adding another 30 horsepower could take off another half a second? I think so. VS1+good cat back = 12 sec. club. Now I just need to buy a rex. waiting--->

I beleve stage 1 cars with a very good driver will be bracking 12's very constently. I ran the old stage 0 map with only 15psi and did 13.6 and better all day long, with $hity 60 times. I have a very good Idea about what is going to be in stage 1 and I have a good feeling that the stock turbo will support 320hp@crank. The Vishnu cars are perfectly tuned for 91oct so if anyone is running better than 91 they can put the boost up to 16 and with stage 1 do 12's all day long. And with there future intercooler I can see the stock turbo pushing 14psi to 14.5 at readline. At 16psi I push 13psi at redline right now because of my intercooler hoses. I was able to gain 1psi just because of the hoses. Plus the stage 1 are putting 50ftt and 20 more hp. And as far as how much power this would be a AWD, try 226@wheels=282@ crank

I'd tend to agree with jmott, I can't see Stage 1 doing consistent 12s regardless of gas.

IF you add an upgraded IC, fueling, catback and potentially standalone management you could probably hit 12s consistently with the stock turbo, but then you wouldn't be running Stage 1, would you?

You know I'm very opptimistic (Spelling). But for me to lay out the money I need to be. But Dug-e-fresh ran a 13.3@101 with just stage 0. And every one I have run on street I have won by over a car lenth. I really think stage 1 will do 12's.

Well I guess we just have to wait and see who's right until the stage 1 comes out. What is included in the stage 1 anyway?

well i ran 13.3 at 99.7 mph. I think going 12's on stock turbo will be easy. I didnt say cheap i said easy. im putting on the cusco header and iridium plugs this weekend. im crossing my fingers for 12's with bolt ons only and no boost controller or cpu yet. i just have a stronger wastegate that holds 13-14lbs of boost. i think with 16lbs mid to high 12's is attainable.

Try page 2 of this thread for a look at what i had when i was running 12.3. I am not running that setup any longer... i expect i've gotten a bit faster. With any luck i'll have dyno numbers and track times from a totally new setup late march.

Ok...here is my 2cents. I don't think the Stage 1 can hit 12's but I think the stock turbo coupled with the right mods can hit 12's...flame suit on!!!

I checked this link and I didn't see any transmission modifictaions (you did mention stock clutch). So am I correct in assuming you did your low 12 second run with the stock Transmission?

You know what, Time will tell. I'll have stage 1 when it comes out and the very next day after it will be installed I'll be on the track.

Al and Nathen are making big power with monster turbos and fuel upgrades. Like 660in, stand alones, Supra Fuel pumps and pe1820 and now t03/04. In a perfect world Nathen would have pulled a 11 flat and Al would have gotten to is 11.9. These cars are hard to drive with that much twist. With the stocker I really think 12s are in it. EMS is the key to it all.

I ran the 13.332 on Vishnu Stage 0...

and yes I ran it with 98 octane...

98 octane that had probably been sitting underground for the last 5 or 6 months. According to a couple tuners in the know, for what I have and the state at which my unichip is tuned for, 98 octane is not gonna make a difference... I will find out though, for the skeptics...

But, I mean how many people pay $4/gallon when the drag race season has not even really began yet. That 98 octane mikaust and I used was probably a real bad idea... it was old and probalby was less than pure....

I am thinking about running again tomorrow... I will have ony 93 octane.... if I run I will let you guys know what I got.

But in regards to Stage 1 running 12s... well, I think its possible. HP isn't everything when running the 1/4 mile.

I have heard through the grapevine that I should not be running the times I am running with the theoretical HP my engine produces... but guess what? I am.

At 13.332, and that being only my 2nd run of the season, I think I can improve those times by abit as they are. Nothing major.... but I think I can take a sneak peak into the 13.2s with no other mods! Hardly anything more to do than just drive better, eh?

Stage 1 will at the very least pull 2 tenths off my time!! I also think most people are caught up in the peak of this versus the peak of that.... and peaks are important....but, the area under that entire curve is a more telling story in regards to overall power and performance increases.....

In a 1/4 mile charge (even nmyeti) you use 1st, 2nd, 3rd and 4th gears only...

Shifting at 7000rpms (instantaneously) in 1st would drop you to about 3900rpms in 2nd

Shift at 7000rpms in 2nd and you will drop to about 4900rpms in third...

Shift at 7000rpms in 3rd and you will drop to about 4900rpms again in 4th.

So in a 1/4 mile run you need good power all through the RPM band because of the launch in 1st.

From there on out you need power from 4k and up...looking at Shivs dyno curves of the Stage 1 over Stage 0, theres huge chunks of area under the curve between the 2, especially in the 4k to 55k range.... right in the sweet spot where the tach falls when redline shifting!!
