Picked up a 2000 Formula about a month and a half ago, been to the strip 3 times since. First two times I managed 13.3s around 107, but it wasn't till I did some datalogging and put on a wide band I found a problem, it was horribly lean! Turns out the MAF was all gunked up, screwing up WOT fueling to the point where it was at 16-17:1 at WOT! Cleaned it up and car felt a lot better, so back to 131 Motorsports park in Martin MI I went.

Its a V8 6spd hardtop, 48k miles. Came with an SLP lid and K&N. I have unlocked the computer with HPT, made sure it hits its AFR targets with the wide band, and gave myself a few hundred extra RPM. The car has yokohama YK420s on it still. Rest is stock and it weighed in at 3610 with me in it:

60': 1.99
330': 5.56
1/8th: 8.42 @ 86.35
1000': 10.87 @ 100.15
1/4: 12.93 @109.60

Backed that up with:

60': 2.02
330': 5.60
1/8th: 8.47 @ 86.35
1000': 10.92 @ 100.81
1/4: 12.98 @ 108.81

2nd run there I left in 3rd and banged the limiter the last 30-40ft just to see if it made a diff. Probably a wash. Didn't do a huge burn out, but did roll through the box and cleaned them off pretty good in 1st gear. Still learning the car with bearly 20 passes total, and im REALLY happy with the results so far. Planning the normal bolt on mods for now and hopefuly will get mid 12s pretty easy.

nice runs. I have a '99 formula M6 t-top car with an SLP lid and K&N filter but dont even come close!

what did you raise your rev limiter to? I had a buddy raise mine to 6400. we were going to do some datalogging with a wideband but decided to wait until I do headers.

Congrats! Gotta love a car that's fast right out of the box.

I picked 6500, it helps in 1st and 2nd mainly, also helps at an autocross with longer courses. Looking at the datalogs, I shift around 6400 on the 1-2 and 2-3, the first 12 second run I shifted to 4th at 6000 so I could acutaly have some time to run it out.

On a side note, anybody notice that both the tach and speedo are horribly laggy? I was quite suprised at hitting the limiter while the tach was only around 6300 rpm er so. Rather annoying if your trying to be consistent. Speedo was bearly past 105-106 at the end as well.

Thanks! I was fairly happy with the lower 13s, but after fixing the MAF issue I knew it had a little more in it. The strip was in darn good shape as well, so that probably helped. Would have been nice to have a sub 1000ft DA though

op... how much do you weigh?

About 255ish. First scale I was on was a scrap scale, said 3560 with 3/4s tank, spare/jack and me in it. The drag strip scale on my first trip EXACTLY the same way said 3660. The 3610 was the drag strip scale, only with bearly enough gas and the spare tire out. Between the 2, the strip scale is probably more accurate. I could see a scrap scale read a little low on purpose. Puts the car around 3300-3350, which is about right for an Fbody, or is that kinda light?

you what you dumped the clutch at? and are you running drag radials?

It wasn't a dump realy, I held about 1800 rpm at the lights and did I guess what would be a medium speed clutch release, and as it caught, added in throttle. The first 12 second run stuck out to me as it happend, I knew it was good, hardly a bog and it just clawed its way off the line right at the edge. I love launches like that The 2nd one had a bit to much clutch slip to be as good, and I called it a day because of it.

Tires are craptacular Yokahama YK420s. Not sure if they're original to the car or not, but I've never been that impressed with them. Also not sure about drag radials yet. I'd rather have the tires be the fuse vs. the clutch or 10 bolt.

Your car is pretty strong to be dam near stock. congrats on your et.
