FFFFFFFFFFFUUUUUUUUUUUUUUUUUUUUUUUUUU

Ran it 9 times this evening. 3 times all motor, the rest nitrous. All my nitrous runs were on a 65 shot, and I turned it on in 2nd (well, one run I forgot and turned it on in 3rd). When I had started running it was like 92 out, my last run it was 72 or so out. Track temps were 108 at the beginning, and 100 at the end.

First 6 runs I was doing burnouts, holding the e-brake and then dragging it out, but it started wheel hopping pretty hard. The last 3 runs I just hit my two-step and launched out of the burnout box and let off when it started to grab, it worked really well for my DR's.

Here's the spreadsheet.

Every run that I used nitrous it was back firing when I'd shift 2-3 and 3-4. The last run it backfired really hard going 3-4 and then bogged so I let out, that would have been my 13 second run. Every run I shifted around 73-7400.

The setup is looking like this:
Stock 98 block with 104K on it
milled .030" stock 01 magnum head
Crane 004 cam (.355 lift, 282 duration intake, 272 duration exhaust)
Mopar DOHC ECU
Crane ignition box (used for 2-step and high limiter)
OBX long tube header
2.5" no cat exhaust
Thermal muffler
Magnum intake shortened and converted into a tube intake
52MM TB
3.94 trans
Phantom Grip dif
ClutchMaster's stage 3 clutch
Full race inserts
Solid bobble strut
No A/C or P/S
No rear seat
205/50/15 Drag radials on stock 2gn 7 spoke wheels for front tires
Zex wet nitrous kit with 65 shot jets

do you have any pics of your car jerry? id like to see how your car looks...

It's a sleeper dude.

The port-a-john's really sell this pic.

The only difference is right now it's sitting on a set of 2gn 7-spoke wheels with drag radials up front.

Well, my track started enforcing NHRA rules tonight, so they said I couldn't run the nitrous without a fire jacket. I ran it 3 times and they pegged me on the last run at the burnout box, said I could either take the bottle out, get a jacket, or leave. I waited for my wife to get there and then took out the bottle lol. On my 3rd run I was late hitting the switch since I had turned it off before the run.

Bottle pressure was somewhere between 900 and 1200 (best I could do was with a mirror and kinda looking) so it wasn't running it's hardest. The only thing I changed since last week was the plugs, tightened the o2 sensor, took out the passenger seat (just to see) and took out about 25 pounds of random tools. I also had my two step set at 4200, when I thought I had it at 5200. It seemed to work pretty well, it scared me my first run, when I launched it wheel hopped so bad I thought I was breaking everything. After that it stopped doing it and would just hook and go. I tried shifting at different points, on my higher traps I shifted around 7300 on 1st and 2nd, and 3rd I shifted around 6900-7100.

I was so stoked when I went a 14.8 all motor. When I went the 14.660 I was ecstatic. After last year of a 15.1@93.5 I wanted a 14.70 on the motor. The air was pretty good tonight, but the track wasn't quite there. In 2 weeks I'm going to Cecil County dragway which is supposed to be a full tenth faster. We'll see what happens between now and then.

Also, hit a scale at the track. It said the car and driver weighed 2660. That's without AC or PS stuff, the passenger or rear seats, trunk carpeting, and a half rad. I know there is 70 pounds in the driver that could be take off, but still, it weighs 2360. I need to find where all this weight is in the car and get rid of it. I'm thinking about taking out the crash bars, but I drive this car on the street and don't want to get totalled when someone else does something retarded.

Here's some vids my friend took of me:

The first video is my first (and fastest) run of the night. When I went to 4th and backfired my buddy I was racing in the SRT said it shot 3 foot flames out. His car eventually went a 13.50 after we reset the ECU.

Well, took her to the track again today. I went up to Cecil County since a bunch of guys from work were up there. Here's what I did today:

First run: I ran my street tires (195/60/14 Falken 329's at 32PSI) and it was wicked wheel spin.

60': 2.433
330': 6.405
1/8: 9.555
1/8 MPH: 80.54
1000': 12.200
1/4: 14.414
1/4 MPH: 102.44

That run, everyone was saying the track was hooking, etc etc. I launched off my two step and obliterated first gear. I wish there had been a vid of it. I was bouncing off the limiter, went to 2nd and then started spraying. My buddy came up to me after the run and said "I don't know how you went anywhere, your tires were on fire through first. And it looked like the car exploded when you went into 2nd gear". It really hooked when I banged 2nd gear.

This run, I borrowed my buddies SRT-4 slicks (M&H 24.5x8.5x15) and used them. My other friend kept yelling at me to spray first gear, so I did.

60': 2.062
330': 5.737
1/8: 8.773
1/8 MPH: 81.55
1000': 11.354
1/4: 13.539
1/4 MPH: 103.32

I turned off my two step so that it wouldn't cut spark going down the track, launched around 6000. It spun a little, kind of bogged, and then I just turned the nitrous on and held on. It was so !Muffler Belts! fun. I really need to get a good set of slicks for my car, but in 22" or so. The M&H slicks are 1.5" taller than my street tires, so it was killing my gearing. At the line as I was revving up I noticed I was rolling forward, so I just dumped it hoping I wouldn't red light. I ended up with a .031 light, it was bad !Muffler Belts!.

All in all, I had a great time. The car runs 13's now, gets 30-32MPG, and has a badass corbeau seat I got from RandomZero (pics later).

setup a line lock on the rear brakes that is controlled by a switch on the shifter. before you stage, push the button give it a little brake pressure and then bump it in.

or use the e-brake like i did. just a couple clicks is all you need.

I was thinking about using my e-brake switch (the one that turns on the BRAKE light) for my two step. I figure if I tape the button down, hold it when I stage, and let the spring bang it back down when I launch, it should be good to go, and give me a few miliseconds of pre-load on the two step to get the car moving.

how is your car so heavy? put that thing on a diet

INVUJerry · Post by **INVUJerry** » Sun Jul 19, 2009 10:53 am

I gotta put the driver on a diet

. 300 lb driver FTL.

The car still has full interior from the seats forward. All carpet, airbags, dash, sound deadener, everything.

I took out the rear seats, the trunk carpet, the AC, the PS, and have a half rad. I still drive it to and from work (30 miles one way) so I don't want to FULLY gut it just yet.

I see you have an Obx lth. How do you rate the quality of it? Any fit and finish problems with it? I'm considering getting one for the coupe and I value your opinion.

INVUJerry · Post by **INVUJerry** » Mon Jul 20, 2009 7:22 pm

The fitment of the OBX header is better than my original AFX and my Fast Fab v2 header. The finish is pretty decent.
