Well, I only beat my best time by a few 10th's. But I wanted to get some input from ya'll, here's a few of my times:

60' 2.065
Trap 81.3mph
ET 8.638


60' 2.028
Trap 81.2mph
ET 8.600


60' 2.040
Trap 80.3
ET 8.677

Now, what i did different in this track visit, i had taller slicks, 24" slicks instead of the 22" slicks. pressure was at 13-14. The ENTIRE night the best 60' I could do was 2.0. Now i dont know if this is normal or if im doing something wrong. I was spraying a 50shot at the launch. Also I was doing better burn outs than before, on one run i spun the slicks big time. Whats the best 60' anyone has gotten out of a stock stall on 4th gen with slicks?

Also, how much different would smaller (22") slicks be with my times?

My previous time was:
60' 2.112
Trap 82mph
ET 8.62

So if I were to use the 22" slicks yesterday and got a 2.0 60', that means i would have seen a 8.5-8.4 ET?

The reason i didnt use the 22" slicks is because i need to have them at lower pressure, but the car is too low in the front and my turbo charge pipe touches the ground. so i need to lift the front a lil bit with blocks on the springs.

 

my best 60ft was a 2.04 with a 8.8 1/8miles, I have a 97 auto, stock tc with a 75shot and milliena wheels on street tires (225/60/15)

I ran the tires at 16psi

my best 60ft with a 55shot was 2.08 with the tire psi set at 18

 

these are the tires I run, bought them used for 20bucks

 

hmmm nice, so it seems that 2.0's is like the limit for a stock tc on us automatics. Thing is, didnt Jime pull 1.#'s on stock TC back in the day on his nitrous 4th gen? Unless it was due to his weight reduction, im on full trim no reduction at all. leather, elec seats, etc..

what are your mph's on the 1/8th and 1/4

 

Buy my TC

 

74mph with the 55shot and 77mph with the 75shot and a loose plug

the tires were at the limit, I think a 1.9 is very possible. I will just need to put some rubber stops in the rear springs and strap the front, so when I launch the rear does not squat

I did not know how bad my car squated till I recorded a run, look at my vid then look at one of jime's an you'll see what I am talking about

plus remember jime had a gle with no sunroof, racing seats, 22inch slicks, a 150 progressive shot which started spraying 10% at 1000rpm

oh yeah and he's just the man

 

what stall speed is it

 

I think he has a 2800. But I wanna go for 3k nothing less. thats IF i ever go ahead and buy one which dosnt look like it anytime soon.

 

oh yeah jime said he found that leaving at idle worked best for him, how is your setup for the track

I know arron, jime and I think grey all strap the front springs and use something in the rear to stiffen it up

when I cut the 2.04 and the 2.08 60fts I left at idle also, everytime I powerbreak and leave at 1500+ rpms it just spins

 

I was launching at 2800 last season......

And I rubber-block the rear Illuminas springs, but don't tie down the fronts....

Sorry - I just saw this conversation.

 

your input is always welcome, I knew you had a tc but was not sure if you strapped the front and stiffened the rear

 

No - but I had a date like that, once.

 

2800 like others have said.

lol ......

 

I really didnt try launching from idle at all, i should try that next time. My nitrous is setup to spray when ever boost is below 5psi. once boost goes 5psi or above, it stops spraying. Since im brake torquing im getting closer to boost from the line, so when i take off its only spraying for a split second since 5psi comes in very quick with nitrous. By launching from idle, its going to spray for longer period of time since the turbo wont be spooled up from brake torque. hmmmmm this might work.

 

spray the whole time


seriously though, were you bogging or spinning? I noticed you said you spun on one run, but didn't mention the others. I'd try running the tires at lower pressure if you can without scraping your piping on the ground. i like 11.5psi personally. in my experience I've had improved traction with tire pressures lower than 14psi and it plateaus around 11.5psi for me.

edit: also when you say pressure was at 13-14psi, when did you measure it. it makes a significant difference whether the tire is hot or cold. you can see up to a 2psi difference from a cold tire to a hot tire right after a burnout and 1/4 mile pass. i liked mine 11.5psi warm (like back in the staging lanes for a few minutes after a pass).

 

Well i didnt really feel bog, most runs felt good from the line, i got a nice jerk back into my seat, but 60' #'s werent really great. im scared of spraying the whole run though. im at 10psi, dont kno if 50shot would but too much considering I already have a mild head gasket problem that iv mentioned to u about. i'll have to keep experimenting with the pressure when i go back to the track. lowest i went was 13psi. i'll try lower next time, thanx for the advice.

 

For my All Motor runs, I found launching at idle or just above works best. It shocks the TC more and you see a higher flash. By stalling it up to 3K rpm, I usually see a slight bog first, then it goes. There's no bog by launching from idle.

For my nitrous runs, I have NO idea yet.

On my last race with the nitrous, I didn't have the front springs zip tied, even though I should have. I removed them a while back b/c they were getting old. I'll have them zip tied before my next track visit. Also, I do have rubber blocks in my rear springs. But I plan to copy what Jime did and put those hard plastic boat trailer rollers over the strut piston and remove the spring entirely. That is why his rear never squatted AT ALL.

I also plan to keep the motor from moving by making an adjustable rod that bolts directly to the motor from the frame. I have PU motor mounts, but there's no substitute for metal on metal firmness.

Edit: Oh yeah, on another note. I've tried launching with a 50 shot on my 22" slicks with 15psi and I still couldn't get traction. The car did wander a lot past half track. With my low race weight, I may be able to lower the pressure some more to see what works best with this strange stuff you call nitrous.

Mickey Thompson recommends going no lower than 16psi if the slicks are under 30" OD with the car and driver over 3000lbs. And going no lower than 8psi if the slicks are under 30" OD with the weight between 2500-3000lbs. Those are just to be used as a ballpark starting point for your car. It matters a LOT how much your car weighs. If you have a full race weight of 3300lbs, you don't want to run the MT 22" slicks at 10psi. Things would get a bit scary past half track when your car starts to wander. But it may be possible to run 10psi with a 2600lb race weight.

 

by looking at the vid's of this track visit, i notice when i take off you dont hear my car really open up, then a split second after that you hear it get loud and really take off, maybe stalling up the TC is causing a lag, im going to try and launch from idle next time and see what i do.

Im going to be using 22" slicks next time as well, i gotta figure out what to do because i cant lower pressure anything less than 16psi cuz my turbo charge pipe touches the floor, might have to do something about that, either put blocks on the front springs to raise it or something.

 

i didn't know you were using mickeys - my advice was based upon my extensive use of M&Hs though I have use MT ET Streets a bit as well. I don't have enough experience on them to give definitive advice but I had 3 runs on them. First run was at 15ish psi and I pulled a 1.92 and then the next two runs I went down to 11.5psi and pulled a pair of 1.82s - that's with no suspension trickery or anything like that - just lowering springs. There was definitely more wheelspin in both 1st and 2nd gear when I had them at 15psi - you can hear it on my youtube videos.
