So I went to the track for the first time in my life, and it wasn't pretty lbs. I drove an hour to the track in charleston in 100 degree weather. My first pass was my best pass and I don't even remember it but I made 9 passes most back to back to back.

The first pass was
Reaction time .9469
60ft 2.4280 and it only got WORST from there
330ft 7.0799
Et @ 594 ft 10.0911
1/8 et 10.7531
1/8 mph 67.97


Did a small burnout.i have street tires Pirellis all season 245/45/18 rear 245/40/18 front Went from idle in drive and let it shift on.
I tried burnouts and non burnouts manually shifting and letting it shift automatically. The most consistent was foot brake to 1500 then let it shift from drive.

And I got what I asked for, and bit off more than I can chew lol. I raced an ss. He had slicks and a year of experience under his belt at that track.

I was so determined to beat him I floored it. It felt like something just grabbed my car to about 3000 rpms then i went flying but by that time he was gone .

Reaction .9669
60ft 2.7279
330ft 7.4701
Et @ 594ft 10.5752
1/8 et 11.25
1/8 mph 66.68

Ss with slicks
Reaction time .9449
60ft 2.1513
330ft 6.31
Et @ 594 ft
1/8 et 9.6272
1/8 mph 74.71

Temp was 100+
All in all I had fun. I forgot to mention i seafoamed my car like the instructions said to let it sit, drive etc then went and an oil change a few hours later. I got 10w40 and Lucas oil and it fixed my lifter tick. I left my subs in the car because I wanted to see how fast the car is as it sits. On the street it just hooks and goes cant break the tires loose if you paid me. At the track it was the complete opposite. I think I may need new plugs and wires because it stuttered and smoked when I was leaving. But on the road home it was strong 60 felt like i was barely moving and 80 to 100 was about 3 seconds

Oh I typed a lot. I know I need help just don't laugh to hard.
If you didn't laugh one of my runs was
60ft 3.0561
1/8 12.61 at 56.10

 

Sure you didn't get a 4.3 L99 instead of a 5.7 LT1???

 

get some real tires and try again.

 

Lol. Yeah, I'm sure it's from a 93 z28.

I pulled on a Harley today from 60 to 100.
And put a fifth gen mustang on my heels on the highway.

 

You think it was the tires bogging me down? Or drs for my 60ft?

 

ever .1 drop in sixty is ~.2 drop in 1/4 mile et. that thing should sixty in the 1.8 range or faster. get some drag radials.

 

If I get some drag radials is that all I'm going to need to get 1.8 60ft or lower?

 

assuming everything is in good working order. i just seen you also have 2.73's. what about torque converter? still running a stock one? even still, upper 1.9x's shouldn't be out of the question.

 

Yup 2.73s and its a one wheel peel or a worn out posi. 1500 stall so I'm guessing stock. I feel like I can get a 1.9 on the street lol because it just takes off.

 

yeah, street tires on the racetrack are like tennis shoes on ice...just not the right tool for the job.

 

You need tires that don't suck, but more than that, you need to learn how to launch your car. I used to cut better 60' times than that with my 2.8 camaro. Until you get better at launching the car, just take off easy from idle, just like you would at a stop light. Ease into the throttle.

That said, based on your trap speed, there's something seriously wrong with your motor.

 

Which is why I asked if it it was a 4.3 by chance. Considering it has been 20 years since that 93 Z28 was built, ANYTHING could have happened to that car, including having a "LT1" L99 installed in place of the original engine. I have seen it first hand with an Impala SS that ran like crap, didn't have the power it should have, and low and behold it had a 4.3 that had been swapped into it.

 

I believe you a completely stock chevy Malibu was getting better 60fts than me, and beatme while i tried to play catch up ( it was my worst pass.) Every pass I just floored it because I didn't think I could get a lower 60ft by barely hitting it.

And I thought the same thing about my trap speed, thought maybe because I was bogging or spinning it affected it greatly since its only 1/8. But by judging my mpg an seat of pants feeling its the best it's ran since I got it in February. Besides my launch it feels strong once I hit 3000rpms. I trapped at 67.98 for my best pass with a 2.4 60ft and a new ss with slicks i think they were trapped at 74 with a 2.1 60ft. And he has about 50 to 60 more hp than me. But if I'm wrong please help me fix it.

 

I asked the seller before I bought it how he know it isn't the 4.3. He said he pulled it hisself from a 93. Then I had my mechanic look at it before he bought it, he said the numbers checked out so I took his word for it. I'm not ready to have a heart attack so I believe it's the lt1

 

There is something seriously weird going on...

An 11.25 at 66.7mph means you are hitting 60 in 9.5 to 10 seconds, 2.8L V6 territory.

 

I did a little video on the way home from the grocery store.
Maybe it can help.

 

is it firing on all 8?

 

After 3000rpm it's a different animal anything before that its a dog

 

well, proper converter and gearing will help that.

 

That's kinda what I was thinking after reading around. I'm bogging at launch and gears are suppose to fix that.

I'm looking for 373s but I don't want to keep my weak drum brakes, and its hard to find a whole axle.
And I just don't have the budget for a $800 converter right now.

 

Guys over a ls1lt1.com think its because the humidity, 100+ degree weather, and tires.

 

check out the jegs brand converters. they're good stuff, they're built by Transmission Specialties out of PA.

example:

http://www.jegs.com/i/JEGS-Performan...rentProductId=

 

I have a Jeg's converter in my th350. works great.

 

I guess I know not to ask those guys for technical advice! Humidity doesn't cause a 50-60% drop in horsepower. Likewise, bad tires will effect your times, but generally not your mph (or at least not much).

 

I ran my 5,600 lbs Titan last night in similar conditions and ran 9.4s at 72-73 mph.

I saw a nearly stock TPI 350 run low 9s last night

 

Opticrap gone bad?

 

Well a new ss with slicks ran 9.6s all day trapping at 74 mph with a 2.1 60ft

 

Told me i slid too much and it was too hot to troubleshoot. Get better tires and try it again.

 

I hope not. Nor do I know how to check.

 

Ss what? If Camaro then it's way down on power to. There not terribly fast but should run better than that.

 

Ss camaro. It was 2 running between tenths of each other depending on launch.

 

Something is not right, a 9.6 1/8 mile is around a 14.8 1/4. The ss I raced last summer in 100 degree weather ran 13.7s all night. Do you know what the DA was that night?

 

On the highway my ipad said 674ft or something like that. But I didnt pay attention once I got to the track.

I raced a awd charger with a hemi and he trapped at 69.73 with a 2.65 60ft. It was test and tune it may have been poorly prepped too.

 

I didn't know they made awd chargers. Unless your talking about the 4wd ram chargers.

Spinning off the line usually won't affect mph much. Look at it this way, lets say you spun the first 60ft then hooked. It would be like taking 60ft off the total track length. So running 600ft vs 660ft is not that big of a difference, because there is very little acceleration going on in that last 60ft. Plus your already moving when you hit the 60ft mark so you have alittle head start. The difference would only be 1 or 2 mph.

I think this the year he had.

But about my car so what does 67 mph but me at hp wise?

 

Somewhere around stock tbi 305 numbers. Can you take some pics of your engine bay, and block numbers.

 

My guess is the da was really high, those ss camaros should be a good bit faster.

 

what track were you at?

 

Enough about the car for just a sec. Let me give you a pointer about your R/T which .9xxx is SLOW. If you wait for green before you put your foot down you are half a second late... When that third yellow goes full, stomp it. You will cut .6xxx all night, then just keep getting braver and going earlier. If you red light, you will still get an accurate time, just don't back out of it. A lot of people redlight and back off because they feel they screwed up. If all you are after is slips, keep your foot in it, the overall time will still be accurate.

PS.. .500 is considered a perfect light on tree..

 

Took a video for you. Block number picture posted earlier

 

It's in charleston il. I think it's called cole drag way it's an 1/8 track.

 

I was leaving after the last yellow light and was still slow lol thanks for the advice.

 

You want to leave as soon as you see the third yellow. Untill you get the car running right that is irrelivent though because a stumble when you nail it will affect reaction times. There is no point in trying to get it perfect now, you would need to relearn when it's running right.

I was talking about the casting numbers on the back of the block. I don't know what or if those numbers mean anything.

It's hard to tell from my phone but the first video sounds like its not running on all 8. The second one seems to be idling high and possibly an exaust leak.

 

Also could you take a picture of the y pipe? My old car had shortys and an exaust shop y pipe. When I took it off it was very poor work, hole was not big enough where the passenger tube connected to the other pipe. You could be leaving some power on the table with a bad quality y.

 

Oh no. The y pipe is nice. They knew I was taking pictures so everything was nice and pretty. I had pictures on my ipad but lost them on a update.

It doesn't run as bad as ya are making it seem. Wot launch is the only weak part in decent weather. Half throttle on the street I take off like a slingshot. But I may have to change my plugs and wires. The plugs and wires I don't know how old they are came with the engine.

 

The high idle you hear is because I just started it up after giving it a jump so the car was trying to give a little juice to the battery. The exhaust leak you hear is actually the puffing sound of the turn down under the car. I chased the sound until I found it. No casting numbers for the back of the block.

 

get slicks on the car before doing anything else. the 2.72 60' is so terrible that it's eating up mph too i believe.

fwiw, our 2.8 car way back in the day ran 11.50's in the 1/8, so yes, i believe there is something not quite right with your setup. but taking lack of traction out of the equation first will allow us to analyze what's going on a bit better.

 

I'm gonna get new plugs, wires, and a fuel filter this weekend. And see if that helps my bog. This maybe a stupid question but can I go to any tire place to get slicks or dr?

 

probably not. i was talking with the m/t reps at the xdrl race this weekend about becoming a m/t dealer and they said it's really tough, which is why i've never been able to find them locally. if you have a big speed shop in the area you may be able to get them that way, but my suggestion (and m/t's suggestion too) is to get them through JEG'S.

 

I have 18s on my car now. But I never see people with 18in slicks or dr. Would I have to get new rims?
