How fast will my stage 2.5(vf39) wrx be?

**dalu3100** · 03-02-2010 10:20 PM

Hey everyone,

I hope this is the right place to post this question. I currently have a 2004 wrx w/cobb stage 2. Im soon going to upgrade to the cobb vf39/stage 2.5 map with vf39, sti tmic, sti pink injectors and walbro 255 fp. Now, my question is, with this setup, approximately how fast will my quarter mile time and trap speeds be. Im really curious to know before I head out to the track once I get this setup installed

Also, what will be my quarter mile time and trap speed w/ a stage 2.5 Protune.

Also, I know that the times and trap speeds will differ from driver to driver depending on driving skills and conditions, but I want to know what the most achievable times and trap speeds are with this setup considering that the driver is flawless and conditions are very good and the track is at a low altitude, etc.

Thank you for your time

Definately in the 12s, not in the 11s though. With a good driver and good track conditions id say mid 12s.

Mid to low 13's would be my guess.

The car in a perfect world with a proper tune and good driving might be high 12's.

I had a VF34 with the pinks on my first WRX. It's been a while, but it seems to me like there were many people with similar setups and Protunes that were well into the 12's.

What times/traps have you run on your current setup?

Not a single one.

I'm no drag racer, and have no intentions of going that way. I suspect that it wouldn't take too many hard trips down the strip for my current engine to shred my tranny.

The question was geared towards the OP, but since you chimed in, have you ever thought about letting an experienced Subaru driver run the car just to get an idea what kind of #s you'd be looking at? Someone who knows what they're doing would probably have a good chance of making it down the track safely.

Oops! Sorry, didn't mean to horn in with an answer that no one asked me.

I'm sorta past the bragging rights thing; it's a wonderfully quick car to drive, day-to-day, that's all I wanted. I'm not even that curious about what it would run.

He's into drag, just not racing. Plus, nothing is worse than a shredded tranny.

Thats how i look at my car, not a 1/4 mile monster, just a quick fun daily driver. Id have something with an ls1 or a f body 5.0 if i wanted something really fast.. and loud. I get to drive my dads z51 vette every now and then, so that gets the speed outta my system. Or if i wanna feel like a gorrila is holding me n the seat we bust out the 69 chevelle ss... its scarey fast n pretty much only goes straight lol.

I was trying to think of a smart remark about you answering, but everything I started typing made me out to be a DB

There's nothing wrong with your mentality. I haven't dragged my car either - if I was looking for a drag car, I wouldn't have bought a Subaru. I just figured for $20 (that's the cost to run at my track), it may be interesting to see what the car was capable of.

i'd guess with a decent driver and a good launch etc... and let's say you're making the average 260-280whp with similar torque range and depending on what rpm you get that torque to kick in looking at high 12s to low 13s trapping 105 +- a mph or 2. used to have a vf34 then switched to a vf48 because i was having issues made 280/275. hated it because of the 2.0L(piggish and no real usable torque for daily driving) now have a 09 making more power with just a downpipe and STOCK exhaust

and hitting peak torque 1k rpm sooner @ 2700. those are just my 2 cents though on basic quarter mile times. hell when i had my vf34(i was probably putting down 250 on cobb ots map before being protuned) i bogged it and ran a 14.2 @ 100 so...driver makes the difference haha. that was years ago though, can safely say i know how to launch my car now.
