1/8 mile ET w/ Tazzo

The urge hit me on a short trip tonight and I pulled out the Tazzo and done a few 1/8 mile runs. Muggy night and 77 degrees at approximately 1500 feet elevation.

60ft - 2.55 sec. to 2.63 sec.
1/8 mile - 10.40 sec. @ 72.0 MPH to 10.58 sec. @ 70.8 MPH

Traction was pretty much awful as you can probably tell.
 
RE: 1/8 mile ET w/ Tazzo

JP, Just to give you some more Tazzo comparison times, here are a few of mine taken over a five month period and the temps. They were taken at about 50ft elevation. The temp and the humidity are usually pretty close to each other in numbers around here.

Temp-----60 foot-----1/8 time-----1/8 speed
_________________________________________
48-----------2.31--------9.47---------78.9
55-----------2.38--------9.64---------77.7
59-----------2.36--------9.62---------78.1
60-----------2.40--------9.78---------76.5
86-----------2.52-------10.05--------75.5

My mods are basically a chip and exhaust. As you can tell, temps and humidity make a big difference.

RE: 1/8 mile ET w/ Tazzo

Picking the closest temp and comparing the two:

---------------- Bill -- JP
Temp -------- 86 -- 77
Elevation --- 50 -- 1500
60 foot ---- 2.52 -- 2.55
1/8 time - 10.05 - 10.40
1/8 speed - 75.5 -- 72.0

No chip nor exhaust for me(yet). I think you have me beat Bill, but I'm higher than you.;) It was muggy(as a matter of fact it's raining now), but I still feel I have poor launches.

The Tazzo rocks.:)

2.55 60fts? You're losing four tenths right out of the gate...

Get them down and you're right there on Bills behind.

RE: 1/8 mile ET w/ Tazzo

Wouldn't higher temps = better traction? I know there's a lot more that goes into a launch, but I just thought when the pavement's cold it's harder to get traction than when it's hotter. Or am I just all wrong?
 
RE: 1/8 mile ET w/ Tazzo

I’ve got several 1/8-mile time slips from the track that show 9.9’s and 10.0’s humid heat. Then I’ve got others that were run in 40 to 50 degree temps that are 9.5 to 9.6’s at 76 to 77 mph with 2.2’s sixty-foot times.

I can tell a big difference in weather conditions in normal driving. On cool days it feels like there’s another 30 hp under the hood than on hot muggy days. Same thing at the track, on those hot muggy days I hardly get any wheel spin but have traction problems on the same track when the temps drop 20 degrees.

While the Tazzo is a really neat “toy” to play with and my times have been very similar to what I’ve run at the tracks, I do have to wonder about the sixty-foot times it records. They do seem to be off from my track times. One day I’ll take it to the track and see how it measures up. It is easier to use that my old G-Tech was but now there are several other models out there that look interesting also. The Cincinnati Microwave folks who make the Escort Radar Detectors have come out with a new performance meter as well as the new G-Tech Pro which can download charts and graphs of your runs to a computer. here's links to several of the meters:

RE: 1/8 mile ET w/ Tazzo

I have had better 60 foot times, the best being 2.34 seconds, still nothing to brag about. But in my defense, I've no track experience at all and the '93 seems to prefer cooler weather for sure. I still have poor launches IMO in cooler weather with more wheel spin but better times. It is just obvious to me my weak point is the 60 foot time. Should I ever find myself at a track, I'm sure my 60 foot times will be my demon.

I don't know about the Tazzo's ability on 60 foot times compared to the track. I can say both the Tazzo and my Mark VIII have seemingly good repeatibility with no erroneous readings from the Tazzo as far as I can tell. If it feels good on the launch, the Tazzo time does reflect it. I do know that should there be a discrepancy with actual track times, the Tazzo can be user calibrated for ultimate accuracy.

Now with all this discussion, what is the concensus for the best bang for the buck as far as the single mod that will do most to improve my 60 foot times(besides the driver!)? My gut tells me gears would do more than a chip in this regard, but I would appreciate other opinions. I have a chip that needs programmed to my EEC, so that would be the least money, but even a new chip would be less than a new set of gears. But what about shift kits, J-mod, higher stall converter, drag radials, etc... remember, we're concentrating on 60 foot times for now.

On cold days,
#1 Humidity is very very low, which is the #1 Enemy to a performance engine, or any kind of engine for that matter.
#2 Colder air = more power.

That’s why they refer to intake mods as "cold-air kit" or “ice box”
Owners install them to shield hot air coming from the engine from going back into the intake.

There’s a big difference in performance down here in Florida on cold days… Right now, humidity is around 95%, which degrades performance big time!

hope this helps.
 
RE: 1/8 mile ET w/ Tazzo

Basically humans breath a lot better as well when it’s colder as apposed to when it’s humid. And by cold I mean around 40F-60F.
 
RE: 1/8 mile ET w/ Tazzo

Gears are gonna be the best bang for the buck, second only to the jerry mod. But making it shift harder isn't going to help your 60' times. Get 4.10's, drag radials, and a big stall, and you'll be putting down some really nice 60' times. Lighter wheels will also help.

JP, sorry I didn’t get back to you sooner but I been out of the country for the past few days. My very best 60-ft time is only 2.29 at the track on a 14.68 @97.42 run during the First Heavy Weight Shoot-out down in south Florida two years ago.

As far a “Bang for Buck” mods, there are many opinions on this and the following are mine based on my vehicle. For me the best mod was a chip. That was my first and I was able to feel the gain immediately. “Seat of the pants” dyno felt like 20 hp at least. Next I drilled out the stock airbox, which felt like a small gain but gave a much better intake sound. Removing the in-fender air silencer will probably to as much or more good for this and I have since done that. “Seat of the pants dyno” feels like 3 to 5 hp (LOL). Depending on you make, base model or LSC, exhaust can help a lot. Originally I only changed out the mufflers on my LSC system. The sound was better and I picked up nearly 1 mph at the 1/8-mile track. Next I did a LMS 900 CFM Megameter MAF which felt like around 10 hp or so. I have since done the XX-Pipe and LMS mufflers. The sound now is very exotic and I probably “sold” about 10 systems for Geno at Carlisle two years ago based on people wanting to hear mine (LOL). Opening up my exhaust system to 2.5” and installing this very free-flowing system seem to lose a little torque on initial take-off but it’s a killer from 25 mph on up. At my local 1/8-mile track I picked up 2 mph over the stock system. “Seat of the pants dyno” says 10 to 15 hp in the upper ranges.

If I were going to do anything else it would be gears in the 3.73 style. Different years and different models my vary. A true dual system on a base model will probably feel better than on a LSC and some early model computers don’t take to chips as well as others. What I laid out above worked for me and my 95 LSC.
