1/8 9.767

mph 90.36

Both of these runs i had massive traction probs I spun the tires through 1st and halfway through 2nd I wish I wouldn't have done the Burnout for the crowd

 

My car runs low 12's @ 110 and my best 60' EVER was 1.65..

I think the 1st time slip was bogus or a clock malfunction. I've driven 11 sec cars that don't 60' in the 1.6s

Based on your ET & MPH if the 60' was 1.64 your car must have lost 2 cylinders past the 60' clock.

Just curious.. how many total runs have you made with that car..

 

I made 3 runs the first run the car grabbed and took off like a bat outta hell and spun the tires shifting from 1st to second the next 2 runs it was like I was on water and had no traction at all. I don't think the clocks were messed up at all the guy I raced none of him times were funny we'll see if it was a fluke in 2 weeks but next time I run i'm gonna put a set of skinnies on the front and lighten the frontend a little bit cause i think it can do better also I'm gonna try and find a set of 16" DR's so I can launch at a higher RPM the tires start spinning at 1300rpms
so I know with a better set of tires I can launch alot harder. I think the reason my 60' was so good is alot of you guys have high stall converter that over power the tires to quickly my car has a more gradual approach and it hits really hard after 10'

 

I looked over your times and your second and third runs are more realistic. I realize these 2 runs are not perfect passes down the dragstrip and you experienced excessive wheel spin but overall they are not off by much when compared to hundreds of other times slips in the 8 and 9 second 1/8 mile range.

Something I have not heard mentioned much is that it takes a pretty strong engine and setup to run 1.65 sixty foot times. If a car doesn't have a lot of power and it sticks the tires really hard it will typically bog off the line which hurts performance.

Where I see the problem with your numbers is that with a 60 foot time of 1.6 you not only have to stick the tires hard (which will hold your RPM tighter and lower) but you have to keep making up time and distance very quickly which requires additional speed which you don't have in your 1/8 mile run. I do not belive your 2nd and 3rd runs are ideal runs but I do think if you made 3 more runs with similar conditions you would find a sixty foot that is higher than a 1.65 and probably pretty close to 1.90 to 2.0.

Have you considered shifting the car around 4,800 RPM into 2nd and 3rd gear? I am not saying it will set the world on fire but if your car really makes torque and not horsepower you may be further ahead to try to keep your car into it's most useful power band. I did read others mentioning shifting higher and I understand the logic behind it but typically that is related more to horsepower than torque. I think if you shift it lower where it is actually making it's torque it will pull the car harder and it will run a better overall ET and MPH.

Let us know how you do.

 

right now I'm open to any suggestions I would really like it duplicate that 60' time if it's possible. so next time out i'm gonna run a set of skinnies up front and remove the front and rear swaybars also remove the rest of the smog equipment. I guess I'll find out if the 60' time was a fluke right now I'm real skeptical just looking at what other cars pull 1.6 60' has really got me worried that the clocks messed up. but they didn't have any probs with the clocks all night and noone complained. all I know is it launched harder than anything else I've ever felt. I' will be sure to update after I go out

 

How the heck can you pull a 1.6 and still run those times? Either I suck at launching or that could have been a track time error. Once at the track I was at, the slip said I did a 1.2 60' but it probably was a 2.2. The best 60' I ever got was a 1.8 on BFG DRs. They are really sticky when heated up. kwik ta has them now. I don't wanna kill my D36 anytime soon.

 

I am with you regarding the clocks being messed up. This may sound hard to believe but the clocks could have been messed up for a single pass only. I have seen it happen with reaction times, 60 foot times, 1/8 miles times that don't match up with 1/4 miles times. Here is one that will get you: I have seen races where the guy gets a better reaction time and runs closer to his dial in without breaking out and still loses.

 

I remember when my old CRX ran a 12.16 @ 917.14 mph. It was really 117.14 mph. They should really fix those errors because they can get really annoying. Ya with that ET, I should have set a new landspeed record.

 

I run a dana 44 with 3.33 at sea level.
60' time is 1.60 to 1.64 that brings me in at 104 to 105 ,running a 12.50 to 12.70 at sea level?.
Everyone says it looks like a rocket taking off, with no noise.
Stock exaust.
Rear tires are MT Streets 28 tall 16 by 9.5.
700r4 trans go kit and 2800 stall.
This is on a 100 shot of Nitrous and the car is dead at the 1/8 mile.
I mean the engine just hum's.
No more RPM no power and you just wave to the other guy as he goes by.
I can say not even the 10 sec car beat me off the line.
They are at 1.54 60'
I think if you are using a dana 36 ,it is about done.

 

Actually it's in my 88 Iroc I have a 10 bolt out of a 98 6spd Z28 with 3.42 gears

 

I agree 100%. It would be almost impossible for those 330 and 660 times to be on the same pass as a 1.64 unless you coasted the last few hundred feet. Timer malfunction, while not incredibly common does happen and I have lost races (fortunate enough to get a re-run when the math doesn't add up) due to it happening.

An earlier post about elevation jeopardizing ET I also agree with. However, I've run in incredible air where the DA was below sea level and run in the high 90s with insane humidiy and the ET difference is .4-.4. Based on my experiences, I still find it difficult to believe that if the altitude was impacting ET that much, that it also wouldn't impact the 60' time.

I realize it sounds like people are ganging up on you here, but those that have been around the drag strip a lot realize this ET slip would be one in a million if legit. I've made roughly 10,000 passes down the drag stip (no exaggeration) and traveled with numerous other races with 8 seconds cars to 19 second cars and not seen a 60'/ET combo like this one.

On the Kuhmos, the 2.0X 60' times and low 15s/high 14s sound right for a car not making decent power in the higher RPM ranges. After selling my Nova that I alluded to earlier, I bought this LT-4 vette. As an example, on Firestone street tires, my best 60' is a 1.94 and the accompanying ET was a 12.93 at 108 MPH. If I had the power and traction to get that 60's in the 1.60s, this would be an 11 second car.

 

I've been doing some searching and have found a few other Irocs that have pulled 1.70 60' with 14-15 sec ET's One guy in my Car club has a 89 Iroc L98 and consitantly runs 1.7 60's and 15 sec ET's
2 examples just to shake thing up

My IROC-Z ran 15.209 with a 1.702 60 ft. at 86or87 mph I have my time slip or you can look at Ultra-z's when he ran the 12.2 I was against him that run so my numbers will be on that slip. Also I'm hoping to have a new time this friday wish me luck.

I somehow managed a 1.78 60' on USED firestone tires i bought for $30 mounted on a 15x7 rim. It surprised the hell out of me but everyone else was running average times in the low 2.XX, which dosn't rule out an error in the clocks 100% but they seemed to be working fine all day.

I went 14.1 @ 98. Didn't pull at all on the top end.
Thinking of those days actually makes me miss my thirdgen for a minute

 

I've had the same thing happen to me... according to my timeslip, I've run 1.2x 60 fts....(my car is a 1.5x 60 ft car).... what happens is that sometimes the timer misses the front tire, and your 60 ft starts on your rear wheels, in otherwords, you now have a 8 foot rollout, thus a 10 mph headstart into the 60 ft timer and you only have to travel about 52 ft or so to boot...... this would easily knock off 3 tenths off your 60 ft time. As a note, this happened more than once to me on certain tracks when I ran my weld draglite rims.... not sure if it had something to do with the rims shiny reflection or not.

A quick tell on this is to look at your reaction time.... if it was particularily late, thats probably what happened. (your rt would be very late considering your car now had to move somewhere around 8 ft)

Your car more than likely also ran its best et to date as well considering you are now racing 1312 ft and you had a 8 ft rollout..... I think my mid eleven car could challenge the 10's with those conditions.

We all agree, tpi motors are torquey motors, but unfortunately, for a 90 mph fbody, it takes more than off-idle torque to get to the 60 ft timers in 1.64..... however get yourself up to 100-105 mph and it becomes doable.

I went back and looked at your reaction times... and on your 1.64 60 ft pass you had a very late .700 rt, your other two passes with 60 fts in the range of 2.00 you had .200 reaction times.....

I'm convinced the start timer missed your front tires and started on your rear tires..... it happens every now and then.

 

Very possible

 

I've never heard of that one, but it makes sense. That would make all the times, all the way down, fast also. His ET WAS quicker on that run than any others. The one thing *I* have experienced, is a piece of paper blowing across the track and blocking an "off" beam (shutting that timer off early) before the car actually gets to it. I have a time slip with me doing 444 mph in the 1/8th. In that case there isn't really a "clock malfunction".

RACE ON!!!

 

I'm thinking some kind of timer problem as well. I know with my car on runs where my 60' is quicker my mph is usually a bit slower, yet on your slip the mph is dead on on all slips even though your 60' is .6 seconds quicker.

 

Hi CFI,

Yeah it happens, but not very often. When its happened to me, it was always sunny days with things sparkling everywhere, but I dunno if they had anything to do with it or not. Its happened to me twice at Irwindale raceway in southern california and once or twice at Carlsbad.

I'd get my slip and see a rt .850 1.25 60 ft 11.15 @ 116 mph......I would have loved to claim the slip as valid, but unfortunately, I've raced far too many years to know my car is short a couple of hundred HP to run 1.2x 60 fts. And in fact that slip would have been a more realistic 1.5x - 11.60 @ 116 mph...... everytime you'll see your reaction time was exceptionally slow, and of course if you're a bracket racer..... and you hit the tree hard and the slip shows a .850..... you know the slip is garbage at that moment.

MPH doesn't change.... simply because it has nothing to do with what happened at the 60 ft timers.... you still started your charge to the last 66 ft of the track from the same point.

This has happened to me twice at Irwindale Raceway in Southern California. You may remember me telling you about it from email a few years ago.... one of the times it cost me an elimination round in the semi's of Summit et points series event. I hit the tree hard and I had my opponent easily covered and dumped a bunch of et at the stripe, but when I got the slip... it showed I was way late and I broke out. I went to the tower and explained to them my car couldn't run a 1.3x 60 ft time..... they would have none of it, and I lost. However, when I was changing tires, the track manager made the point to walk out to me way out in the pits and apologize and tell me he believed me, but his hands were tied and couldn't do anything.... because of that I wasn't too upset... I guess I could see it from his point of view.... a lot of people could make the same claim I guess.

My personal "theory" is that on sunny days with the sun in the right spot at a certain time of day, the reflections can tease the timers.... but thats just a wild guess, I just don't know.

cheers,
Beach Bum

 

Beach,

You're absolutely correct about the mph being unaffected.

Your "theory" on the sun is correct, too. It depends on the orientation of the track and the time of day. Up in Boise, the regulars know to load their front chrome wheels up with polish or put a matte finish on them, just for that reason.

I DO remember you complaining about that incident. Good to hear from you.

RACE ON!!!

 

The polish is a good idea !!!
