Default first 1/4 mile runs for my wrx, SUCKED!

Took the WRX to the track last weekn on opening day. My times where quite a bit less than I had hoped for. Part of the problem was I didn't expect the track to be open for a while and had just filled my tank with 91octane pump swill, so I was forced to keep my boost below even the stock setting. Other things working to slow me down was the fact I left my 19inch wheels on, "basicly I just wanted to get some base line runs".

I learned a lot form my first trip out however, one of the things I learned is my car will not launch at all on the tracks sticky starting line. Even at 6k+ launches I got nothing but BOG!

All of that said on to the times,

1.96 60' <- I told you 19inchers + sticky track = BOG!

13.68 1/4 time @ 101mph

My performance mods are k&n, hks cat/back, vf22, I am running all three cats still and stock ecu.


My next mods are injectors, pump, and re-installing the stock wheels. I think after this short list of things on good gas and higher boost mid 12s should be easy.

All the cats and no engine managemnt and an upgraded turbo that is doing about nothing right now for you. Don't mean to be a jerk but a upgraded turbo on a stock car just doesn't make sense to me.

LOL, I hope your not serious....Thats a good number considering u still have all your cats, and NO CHIP.....The whole boggin issue, u must be doing somthing wrong....oh and DONT launch at 6k please unless your looking for a way to get rid of your tanny quick....with the proper fuel and chip/engine managment your easily into the 12s....anyway, arent those wheels heavy as f*ck too ? that could easily be slowing u down...Friend of mine has a similar setup with no managment and a vf23 and he managed to get a 13.5 on stock wheels....so dont feel so bad, dont take it out on your car by launchin at 6k. =)

Peace

That is pretty good times and trapspeed (101mph) considering you only have a few mods.
Good 60ft time, even with the 19" wheels.


Get a unichip for the vf22 turbo w/fuel sys. upgrade and you should see your times drop.

Those times should drop drasticly!!! You aren't using that turbo. You need to not have so many cats, have some management and but the stockers back on and you should be in the 12's.

Default thanks for the ride

I just got a ride in the car today. I'm sure all of you guys are right, but the car seemed to behave well. It seemed to lack midrange power, but made nice power up high. I think that when the uppipe and downpipe are replaced there is the potential for more problems, however. Hopefully the car will also get a Unichip and some injectors. That will cover most of the "GO".

The car already has plenty of "SHOW". You could eat off of it. The violet HIDs look great. The wheels, even on lowered spring, rode pretty well. Another lightweight set of wheels might be better for racing, though.

Default I forgot

ktrends,

I noticed that you don't have a Knocklink. I highly suggest that you install one. They are affordable and easy to install (one bolt). I'd offer my help, but you can install stuff better than I can anyway. What kind of security system do you have? I forgot to ask.

I'm surprised that nobody suggested that the reason for your bogging may be the restrictive exhaust with the large turbo.

Probably also slipping the clutch a bit more would help bring the 60' times down.

If you're getting those times/traps with an almost 2.0 60', I'd bet you can shave a ton with a decent launch.

He knows that he needs an uppipe and downpipe to unchoke his turbo. I was just wondering if the lack of the uppipe and downpipe is keeping the turbo from flowing too much air that would then cause him to go lean and get knock.

I agree, bogging might be a problem on launch, even at 6000RPM, with too much traction because the car would fall to midrange where there is a lot less power.

There's a dude in Atlanta (WRXeFEX) that runs a vf22, 3" catless turboback, intake, uppipe, and unichip (maybe a few other mods also). He turned out ~250whp on turboxs' dyno. He had a hard time breaking into 13's this past Friday (i did a best of 13.40X with highest trap of 101.3)...funny thing is the week before he was running 13.6-13.7's but on his last run (without any cool down) he ran a best of 13.2. I think the BIGGEST factor keeping him from low 13's-high 12's is the fuel system. We were racing on the freeway and we were DEAD EVEN. Until 5th gear. (which I missed).

The wheels are too tall and heavy for getting a good launch and slowing acceleration in general for the strip. Though they do look nice I have to say So next time put the OE wheels back on.

Anyways, Launch at a more suitable 4500-5000rpms and slip the clutch just enough to get you going off the line. As soon as you start to roll let it all the way out and you'll be at a low 1.8x for sure.

All in all though, a 13.6 isn't too bad. Considering the turbo is making more power than the OE turbo in the higher rpm range and I think your trap speed reflects that. That VF22 running the stock mapping and ignition is somewhat dangerous I would think. Plus, I wouldn't go too high on boost until you get more fuel going on regardless of fuel/ign mapping.

You are right. He needs fuel. When he has fuel and 1.3 bar he will blast into the 12's.

I find it hard to believe that someone with 250WHP has a hard time breaking into the 12s. Does he really need more fuel? I thought the WRX tends to run rich as you increase the boost. Please clarify for me.

He has a VF22. Stock Fuel system is WAY under spec for that turbo.

That's true but what about all of the Honda guys with hubcapless steel wheels in the front. I laugh everytime I see most of those guys driving around because they think it makes their 16.99 Civic DX look like a drag car. I mean most of those guys doing that look DON'T have slicks on them which is why you'd have ugly black steeel wheels on it anyway. Oh well, to each their own world.

By "fuel system" do you mean the pump and the injectors?

I thought they did that to try and challenge WRXs in bad weather? I mean throw some all-season tires onto a Civic (in the front) and it will probably have better traction in inclement weather than most performance tires...

In his application, yes, just a pump and injectors will help out TREMENDOUSLY. FPR (something like cartech), upgraded fuel rails, fuel controller (ex: along the lines of an apex'i s-afc...or some ems or unichip would do), colder plugs, etc...etc... would be beneficial also. I took a look at his dyno sheets and he was running pretty lean. Injectors were going static towards upper rpms.
