I ran again today. Weather was a bit warm (mid 70s) with a low pressure system moving in. I ran a handful of 14.7s-14.8s@96+mph. And then, after hot lapping 3 run back to back runs, I ran a 14.68@97.79mph with a horrible 2.301 60'. Has anyone trapped out this high in a NA 4th gen or even a 5th gen 2k1/2k2? I ran a whole .01 better, but my trapspeed went up a little over 1mph Most runs were in the 96mph range with one in the 94mph when I missed 4th gear running against a CL-S. I still won though. It's time for drag radials. I couldn't do better than a 2.29 60'.

Congrats to BSwithTF (Travis) and ShortChaz(Charles) running personal bests. Travis ran a 15.28@91+mph with a 2.3 60' in his GXE auto with a y-pipe, intake, UDP, JWT ECU, catback (?), and 17" rims. Charles ran a 15.6@90mph with a 2.30 60' in his 5 speed SE with an intake and a VERY bad clutch that slips on every gear change.

strong tailwind?

i don't see how you can ever get a 2.1 i only dragged 5 times in my life.. and i get consistent 2.1's and 2.0 twice

Dave B

Different tracks. Let me put it this way, on slicks most guys in F-Bodies and Stangs are pulling 1.8-1.9 60's. Drag radials you're looking at 2.0-2.1 60'. During the National Grand Prix meet, all the out-of-towners were slower by .3-.6 seconds and most of the gain in ET was in the first 330' (ie no traction). Take it for what you will.

As for a tailwind, yep it was a bit windy. The track runs southeast to northwest. The on-track weather station said winds were out of the west/southwest at a steady 10-15mph, temp at 71-74, baro at 29.6 and falling, 60% humidity. 2 hours into racing, the winds had changed to west/northwest. I can't imagine the wind would play too much of a roll in my mph seeing that most of the wind was a cross wind. I could be wrong though.

For comparison, I ran a 01 Mustang GT 5 speed (with drag radials) when I ran my 14.68@97.79mph. He ran a 14.30@98.90mph with a 2.2 60'. I'd think that if the wind was helping, it would have helped the Stang too. His trapspeed looked pretty normal for a lightly modded 01 GT at my track.

yes Etown does own man it takes a good 15 mins when someone spills oil on the track .. but the high tech equipment they have an prep just owns

VeeTec

That is impressive. I can't wait to run with a new cat. I wonder how much I was losing with the old one.

Congrats on the high m.p.h.

kit99bar

very nice runs dave!
my friend's bf in his VR4 got a personel best of a 13.0 @ 106
that's .5 better than the day he went with me in November.

man I regret not going now. I didn't feel the urge to go, and I had lots of stuff due monday

well I'm gonna go next weekend for sure
I got an interview with Cerner on Tuesday so I'm just gonna stay in KC till then

I ran today in Md.
When I started to drag my car(last year), I had 17in MOMO sports and a K&N POP Charger. My first run was a 16.2, I'm a 5spd I30t. I came back the next week and did a 15.9 consistantly with an occasional 15.7. I put a WSP Y pipe and I was doing 15.5's consistant with a personal best of a 15.3.

Today I was running on stock rims with 5 y/o toyo 215/60R15's with an additional Greddy exhaust.
my times were
15.080 @ 93.6934 / Rt 1.0937 / 60ft 2.3344
15.301 @ 93.3319 / Rt 0.8078 / 60ft 2.4595
15.056 @ 93.9904 / Rt 0.9445 / 60ft 2.3617
14.895 @ 93.7812 / Rt 0.5201 / 60ft 2.2614
14.785 @ 93.8438 / Rt 0.7853 / 60ft 2.2495

I do have a question though, how did I go slower and complete the 1/4 mile faster? I range in .5 sec time frame without going 1mph faster?

ericdwong

Hmm, very interesting indeed. I've pulled 2.1s before at my local track on a busted rear motor mount and stock suspension, but my ET is never above 93 mph, even when I ran my 14.6. Fortunately, the track is open again for this season, and I anticipate going this friday. One thing about my track is, the water box is almost unavoidable. At least one tire usually will get wet. Fortunately, I now have the Quaife differential to hopefully stop wheel spin. My home made polyurethane mount should be done by this friday as well, so we'll see what happens. I'd really like to drop the car, cause the stock SE suspension has way too much play and weight transfer.

Dave B

Congrats on the solid 14s. The reason you dropped .5 seconds, but added little in trapspeed is because you hooked up much better. It has been my experience that for every .1 you shave off you 60', you drop over .2 in the 1/4 mile. Trapspeed tends to flucuate very little vs ET. Trapspeed is a great indicator of "potential" ET.

I noticed that before, I could finish in 3rd gear with out hitting the REV limiter. Today I smacked it hard on the last run(14.7), is it better to ride it out or shift? It like in the last 100ft or so maybe less.

So do you think I should get a UDP Dave? BTW, awesome times! It would be great to see what your car could do at a stickier track.

Dave B

I'm of the belief that shifting to 4th is mandatory after multiplying out my shiftpoints from my dynographs and overall gear ratios. I shift my 1-2 at 6500, 2-3 6200, 3-4 6000. I'm shifting into 4th ~300ft from the final timing box. Make sure to shift fast. If you don't know how to hit 4th fast, post back. If you hold on to 3rd, you're making no power and are running close to redline. I don't even think I could hold 3rd now without hitting the rev-limiter.


Dave

Dave B

Definately, if they make one yet. I don't think I'd be putting a 95-01 pulley on the 2k2 unless Unorthodox says it's okay. I think the combonation of my Warpspeed Y-pipe and UDP really did make a big difference. Now if I could only put down the power

I am trying to figure out if they do make a UDP for my 02. I think the 95-01's fit the 02 since custommamxima.com has the 02 listed as fitting.

Next week I am going to dyno my RT cat and Greddy exhaust, I am also going to try a different intake setup back to back. After I do this I think I am going to get the UDP and get a real solid dyno done on it for once and for all! I would do them all at once but in the event my car is making less power or something I want to know exactly what is to blame

maxfreak_98

Those trap speeds are truly awesome, Dave. I've had no luck in getting my traps any higher than 94 (14.73). Shifting to 4th always lowers my ET's slightly .
I'd like to see what my car will run with cooler and less humid weather conditions.
Overall, I'm pleased with the performance of this car for what it is.

Like I said I bounced off the rev limiter twice on that final run. When I shift into 4th, I just pull it down into 4th. Is there a better way?
