The whole 1/4 mile scene is another language to me. What kind of MPH does one need to get into the 11's?

[themyst]

I've seen N54's trap 114 get into the 11's. It's all about how fast you can get off the line.

edit- you have an Xi. You may be able to trap 114 or even lower to get into the 11s

Technically,113- 115 if you can get off the line hard enough.

[Q4P]

Your AWD so just for the hell of it; i'll tell you Evo's can hit 11's with 116 / 117 trap speeds.

You better be getting off that line like a champ...

[jpsimon]

ok another question, what do you guys think I can trap? FBO+93 octane only, full weight (~3900lbs with me in the car)... and I'm talking on the street (in mexico), not a prepped track.

Ive seen some Mustangs cut some 1.3 60's

JP I would hope you trap atleast 120 with upgraded turbo's.

[jpsimon]

my shitty turbos aren't anything like RB's.

no meth, straight 93 octane

lol, vbox eh? Just make sure you find a road with minimal slope straight as an arrow.

I have no idea what kind of power you're putting down, but you do have upgraded turbos. I say 11.8@115 without meth with a high 1 second 60'.

I recall a FBO 93 pump JB4 xi with 6AT run 12.2@112 local around here. so I'm overestimating.

[Q4P]

I haven't seen too many xi's run, does anyone know the XI n54 record? 3900 lbs is a heavy car though but given your mods I would say in that 114-115 or so range especially with no meth.

[bigdnno98]

Myst, what meth kit are you running with the Cobb? i can't wait for ATR to come out so I can put some meth on the car!

Plain Jane pressure switch activated basic kit with a single CM10 nozzle. I have a failsafe that vents vacuum during a low flow condition but I haven't gotten around to installing it.

If you want the best, HFS-3 by Aquamist. But in my testing along with another who run basically the same meth kit, the basic kit works just fine for all intents and purposes.

yeahh, it's toughing finding a good stretch of highway. Everything is very swoopy around me. half a run may be going downhill the other half right back up hill

If you're ever down in the NYC area, let me know. I'll tell you about a great stretch of road for both 60-130 and quarter mile. The 60-130 road is a 2.x% slope so it'll give you an advantage AND below the 3% "verification" limit. You could run there all day without any problems

Launch with good wheels and tires are key. Aim for 1.7 - 1.9 sec 60' times, with your mods 11's are easily acheivable. I've had bad launches, 2.2 sec, and had traps at 120 that still didn't break into the 11's (that thats with my street trim 19" wheels + street tires).

Yeah, making WAY more power than anyone here.

And their rear tires are Hoosier balloons compared to our tiny 275's.

I have 19's with toyo t1r's. 275 in the rear (19x10). Traction is starting to be an issue even with AWD now that the temps are dropping. I need to launch at lower RPM with these summer tires in the cold weather i think.. i'm getting a lot of 4-wheel-hop when i go for too high of a launch

The question was what trap was needed to run 11's. He never said what car or what driver or what power or if it had a solid rear axle, skinnies, a parachute and slicks

But there are trap speed calculators on google. That is what I used. Either way JP should have no problem hitting 11's with a nice launch.

I have a 2008 335xi coupe automatic and with 93 octane and cobb stage 2+beta, helix fmic, ar catless dp's, and Injen intake. Here is my slip. I expected better numbers considering I ran a 12.6 with just cobb stage 1 and no ther mods.

There's nothing wrong with that slip. You are trapping nearly 115 MPH on pump gas with a heavy ass xi. Trap speeds indicate the power you're making, ET means how fast you can get to the end. I would also imagine launching with the extra power is a bit more difficult as well.

With that trap speed you should be able to crack into the high 11's. Keep practicing!

I think he was saying that he expects JPSIMON to get better results than that, seeing as he did a 12.6 on stock turbos and COBB Stage 1
