Glen, I do not have the post in front of me, but I will make an effort to find it.

95MTX, 3.0, stage I cams, 80mm, CAI, y-pipe, catback, UDP's
[email protected]

The Stage 1 cams you speak of are from Sho SHop, correct?

 

[RJ-92]

NA (3.2, cams) = 14.42 @ 99.5 MPH
+ 75 shot = 14.07 @ 103.0 MPH The vid

Time slips are available if I can figure how to post them.

Here is my post to the SHO lists back on 10/28/2000. I still have the timeslips in my files somewhere if someone wants to see them. Conditions were near perfect (actually, about as perfect as they could be!!), as was the track condition. That means I was able to get a few feet of wheelspin on the ATX to get it into the power band. I had run a few 14.9xs a few weeks earlier, and had run some in subsequent dragstrip trips.

I had bought the car new, and broke it in "properly". It had a UDP, the "Porterized" intake, bypassed TB coolant, K&N panel filter, and turbo mufflers.

Scott also ran his best times. he had a Gen 3 with Nittos and a 75 nitrous shot. he did a best of 13.80.

+++++++++++++++++++++++

Scott Waters & I went out to Lapeer Dragway today. Better Conditions than a
few weeks ago (for me), running without the 20-30 mph headwind helped. The
stats were:

Weather: 49-50 degrees and sunny, around 56% humidity. Winds NNE @ 12-17 mph
(the track faces NW), barometric pressure 30.36-30.42 (I checked The Weather
Channel @ 8AM & 5PM).

Car Prep: I changed the ATX fluid this morning (6 qts Mercon V), plus an oil
change (Kendall 5W-30). I've been driving around in D2 (non-OD) for the last
couple of days trying to burn off the tank of gas I put in for the car
weigh-in last Monday. Usual weight out (mats, spare/jack, loose stuff). Only
new thing was running without the wiper arms, as I pulled 'em to Rain-X the
windshield. Approx 4 gallons of 87 octane gas to start, Low Fuel light came
on after a few runs. 50#s air in the rear tires, fronts varied (see Notes
below). Also note that on the last 3 runs, I covered the Swiss-Cheese airbox
holes with duct tape, and just drew air through the PVC intake.

There were more cars running today, and more hot cars (water burnouts, etc)
so lane-to-lane traction varied.

I raced Scott the first two runs, who ran without NOS, and he had his
exhaust closed. He can fill you in on those times (he ran well, but I
won!!). R/Ts for all runs varied from .557 to .793, but I didn't care as I
was looking for ETs. Lanes are Tower (T) or Spectator (S).

2.163 9.661 77.26 14.845 94.69 S 36#s, plus covered airbox holes
------------------------------------------------------------
Avg ET/speed: 14.859 94.92

Observations:
The car was touchy to tire pressure, 40#s in the front was too much, 36#s
felt good, 32#s didn't feel great, although the 1/8 mile stats were
consistent....but trap speed seemed to drop.

Covering the swiss-cheese holes in the bottom of the airbox (14 1/2" holes)
made no discernible difference in times. They are staying covered, as the
"drone" while cruising can be annoying. It's obvious (to me) that the 3" PVC
pipe feeds enough cold air to the 2.75" TB (along with the K&N panel
filter).

The 14.673 run was perfect!! (almost) better than sex!! It was the perfect
amount of wheelspin, and the motor never dropped any rpm when the tires
caught! It was the best 60' and the best ETs & mphs across the board I've
ever had. I wish I could duplicate it, but it was more the lane condition
than anything....you can't do much when you just punch it off the line!!

Overall, a fantastic day for my last runs of the season. When I bought this
car, I never expected it to be a runner, but it does damn well for an ATX.

Dang! What I wouldnt do for a 2.078 60'. If I ever get one of those in the turbo, that would equate to a 12.8 or better.

 

[RonPorter]

Yep, 60' times are where it's at!!. I got a 1.983 in the Subie for my 13.90 run. Besides the additional power from my reflashes, to get the ETs to at least the 13.60s will take more care in the launch to drop the 60'. After that it's just a ride to the finish line (well, unless you blow a shift!!).

 

[SHO-93-ATX]

Wow ron, when you pulled the 2.0x 60ft and 14.6 1/4 time what car was that in and what mods?

thats excellent running weather to in michigan

That was in my '99 that was mentioned in the sig at the bottom of the post. had 25K on it at that time.

That car had a LOT of 14-mile runs on it, starting at about 2,000 miles at the '99 Atlanta Convention, up until I sold it in late '01.

Basic mods were the UDP, TB coolant bypass, "porterized" intake (3" PVC from the stock airbox into the fender, with a K&N panel) and turbo mufflers.

I never made a big deal of the 14.67, as I didn't back it up with a close run (but I know why the car did run that well on that run). What impressed me about that day is that all 10 runs were in the 14s.

 

[DavidT]

those times are phenomenal! Is that solely due to the 50 degree weather? I have never ran at temp. below 75 degrees, and there is NO way I could sniff your times w/o FI.
I see that was at Lapeer... I know recently, there was some screwy times there... are those times you ran back then dependable? (Not doubting you, but wondering about the quality of the racetrack)

 

[Silver95]

perhaps it was a factory freak? or "porterization" really helped. just a quick q for you gen 3 guys....how much time will be knocked off with a VAK system?

First off, there's nothig "scewy" about Lapeer. Times have been verified against other tracks. Some folks (like the F-body crowd) claim that the times are "slow", in fact!! The track surfqace used to be terrible (as I hear), then they completely resurfaced it in '99. When I started going there, it was nicer than Milan (the IHRA....former NHRA....track).

Look back at the conditions, they were probably perfect. OTOH, there's a whole history behind this one day. I had probably had well over 100 runs on that car during that season, documented for conditions, as well as experimenting with various things. The car run a few 14.9Xs a few weeks earler with a headwind. I also ran 14s after that day. That particular day was unique in that all the runs were in the 14s. We also got Ryan Dudek's black '98 in the 14.90s with the same setup. There's a bunh oflttle thins that were tried, but sufficient to say, this was not an outing for a track newbie.

FWIW Gen 3s are more heat sensitive than the Gen 1-2 cars. It correlates to about a tenth per every 10 degrees of temp from 40 degrees to about 90 degrees, with the other factors equal.

Also, even though it was an ATX, there was two tenths to be gained just for driving. When Dudek first took his out, I was two tenths quicker than him in either car. After he got 75+ runs under his belt, that two tenths went away. Driving experience DOES matter, even in an ATX car.

 

[RonPorter]

It was defintely on the quicker end of gen 3s. But then, every new car that I have bought since the late '70s has been broken in with the "drive it like you stole it" method, and every one has been on the quicker end of the scale.

There's a whole bunch of little things about running Gen 3s, as wel as some differences of opinion about what works or not. Even though other folks disagree on certain mods, I have (in my mind, anyway), validated my opinions with getting two cars into the 14's. OTOH, some Gen 3s are just dogs.

One test that seems to hold true (if you are considering buying a Gen 3). If the car easily spins it's tires off a launch (and the tires are in decent shape), it's probably a dog, and can't run below a 15.5 going downhill with a tailwind. If it barely chirps 'em, you have a better chance of getting a quicker one. Don't ask me why (lthough I have a few thoughts), but a few of us have observed this over the years. BTW........my car couldn't spin a tire on the street, except in the rain!!

 

[Ian Macoomb]

I believe Lapeer's times are legit. Their 1/8th mile trap speeds are suspect though.

 

[Ian Macoomb]

Nah, I don't buy the factory freak thing. It's just conditioning. Beat on the car regularly and take it to the track in the right conditions. Avoid heat soak at all costs and it will be fast.

And the VAK, I'd guess that it would make a car maybe a half tenth faster at the drags. All it does is **** the field to the alternator, **** the A/C and **** the SARC making the struts firm and the power steering less (???). The same thing can be achieved by not running the AC (which you shouldn't do at the track anyway) and pulling the SARC fuse. You could also pull the fuse to the alternator but that will lower the voltage to the ignition system. The beauty of the VAK is that it does all this for you on the fly. Better for everyday driving or road courses than the strip.

 

[RonPorter]

Occasionally, for cars that turn between 80-90 trap speeds, the speeds will print about 10 mph low.

 

[DavidT]

in the 1/8, I approximately gained 1 mph in the trap, and MAYBE a tenth in the ET, iirc. (I ran a 10.2 at 71 mph in 80 degree weather with a 2.4 60 ft.)

As for spinning the tires (gen.3's)... I must have THE factory freak. Unless I am on loose gravels, I can forget it

Ron, how did you pull off a 2.0 with NO wheel spin? That is amazing!

Also, your right Ron, I was referring to Denny's trap speed in his 3.2 mtx (82 mph, iirc)

 

[Ian Macoomb]

That too. But I was talking about the 1/8th traps. I ran 75+ mph traps with slow times. At every other track I ran much slower 1/8th traps with similar or better ET's.

For example, this year at the convention I was running 15.3-15.4 with 1/8th traps in the 72-73 mph range. I ran the same ET's at Lapeer with 75 mph or better traps. Even my runs in the 14's didn't have 75 mph traps.

I think Ron is saying that he had a good amount of wheel spin. If you don't get any wheel spin off the line the car will bog. Too much and it goes nowhere. If you get the right amount the car gets into the powerband and takes off.

And my car can barely spin the tires and it's one of the quicker ones.

The entire trick with an ATX SHO s that you must get light wheelspin at the track. The ideal is light spin until the secondaries open up. You want the rpm to be rapidly rising without the tires in a free spin. The factors for this are having good atmospheric conditions for the engine to run right, but then you need good (ie: not sticky) track conditions. You can affect it to a point by playing with tire pressures (as in; go a lot higher, 45-50-55 psi), as well as moving over in the lane to get away from the heavy rubber areas. You are basically doing the opposite of what the traction-limited cars (like MTX SHOs) are doing.

Some days it's just not possible, you can't get anything beyond a chirp. However, a quick look through my old posts shows that I had gotten to at least the 2.17x range (possibly to 2.158, but my notes weren't definitive) without tire spin on a sticky track.

The details are all getting fuzzy, as this ws all from 4-5 years ago (and I do have most of the posts from all of the drag days we did through that period).

There's a whole flock of other things we did, from running the tranny fluid down to the lower hash mark (count on 3+ tenths if you run it overfull....tested & proven), car prep with removing weight and low gas loads (but seats in place), 60+ rear tire psi, trying to pick good weather days, buying good (non-alky) gas, proper lane staging, proper launches, etc, etc. And obviously, driving experience.

it's no one single thing or mod, but a whole bunch of little things that add up.

And you have to be seeing a sub-10-second ET (more like 9.8 or better, IIRC) and more than 72 or so trap speed in the 1/8 to even think of a 14-second slip in an ATX.


Yeah, his 82 trap speed was really a 92.
