VF34 First time at the 1/8

JonR · 05-26-2007, 10:11 PM

Couple of the better (relative) slips:

RT .251
60' 2.186
1/8 ET 9.147
1/8 MPH 80.826

RT .860
60' 2.311
1/8 ET 9.407
1/8 MPH 82.059

RT .425
60' 2.352
1/8 ET 9.495
1/8 MPH 82.109

So, basically, I suck at launching the car, but at least from what I've read, the trap speed is consistent with the mods (according to hotrod's conversions, it would trap around 104 or so in the 1/4).

In the 1/4, I know a tenth off of the 60' is .2 in the ET, I'm guessing it's not quite as much in the 1/8 but I figure I could have easily run 8.5's if I can get it off the line cleanly. Mainly it was bogging it that was holding me up. Fortunately, this track is pretty empty each week so I can get lots of practice in, which apparently is what I need.

Engine mods:
MRT TBE, high flow cat (probably holding me back most of all, all ceramic and clogged over the years)
JDM catless UP
VF34
Pinks
Walbro 255
APS fuel rails
Ebay TMIC
Prodrive IC hoses
APS splitter
STI scoop
APS inlet
DIY intercooler spray
DIY PNP manifolds
Accessport Protuned by Boxer4racing (road-tune only)

I have an 18g 8cm to put on but I figure I'll try to get my launch down before I add more power. Also, the car has not been tuned since the fuel rails, which I understand can add about 1 point to the fuel maps.

For comparison's sake, here is a recent 1/8th run from my vf39 car, most other mods very similar...

60 - 1.94
1/8th ET - 8.487
1/8th MPH - 82.268

Now my car has fairly weak top end, and finished that run with a 13.2@102

what are you putting down at the wheels?

It has only been road tuned, so I'm not sure.

you need to be more aggressive on the launch. At almost sealevel, I am able to pull:

1/8 --8.7 @ 84mph
60-- 1.75
with stock TD04.

I'm sure your car should be closer to the VF39 numbers posted above.

-Added, do you have wheels? When ever I run my car at the strip, I use my stock wheels wrapped with low pros. This really allows me to launch with out bogging down the car. The lower rotational mass makes a difference as well.

With my VF30 I am going 8.1 at 86 with a 1.80 60 foot. With 1.9 60 foots I am between 8.2 and 8.3 very consistently, never slower than 83.

2.0l
VF30
UTEC not running any launch control

TAPOUT · 06-08-2007, 09:54 PM

When my car was stock, I ran 8.3 @ 82 with a 1.80 60 ft.

It's all about the launch. More revs, quick slip of the clutch.

60': 1.83
1/8 ET: 8.54
1/8 MPH: 80.40

02 WRX stock turbo @ 15.5psi, catless uppipe and turboback, tuned. Made 243whp 240wtq on a Mustang dyno.
