well guys from personal experience racing a modded 350z, well this is what happened, roll from an 80 mph, i was 3rd gear he was in 4th? maybe not sure, well we went i pulled maybe a car or a half a car and was beating him off the line, once we hit about 120-130 mph he passed me and kept going and pulled like 4 cars on me till we hit about a 1/4 mile

 

you raced from an 80mph roll? lol

 

I was drivin home to NC from Texas and i had my cruise set at 80 and some guy in a Honda Accord V6 kept trying to get me to run and im like ******* im going 80 right now there isnt much more to go.. i top out at 108 and im not doin that **** with semis on the road and only two lanes of traffic

 

Yeah, startin at 80 just doesn't seem right. I would have slowed him down to a better speed. Not really gonna show anything from those speeds.

I think the 350's and the G35's are sharp, but around my way the owners all seem to be some preppy pecker heads that deserve to get whooped up on.

 

well, no preppy z owner here. I get my hands greasy everday and work on my own car..

There are alot of stock z's around here also. i get alot of looks from other z owners when i pass them, but it's always someone alot older.

 

he didnt wanna go any slower, b/c supposidly he had his mods all for top end, and in the long run i still got him off the line with a car or so, and then jsut passed me but then i got him from a dig too, he pulled a car on me and then jsut got further, DAM TIRES GO SPIN SPIN SPIN and wheelhop like a mother!!!

 

I doubt a car. even okay, but a car that is not right. couldnt have those mods. IF your car does 13.4 in a 1/4 this is what I know. my car would be able to do the same time with drag radials alone or close to it. How do I know that? our cars are hard to launch (FWD). with dr's my car would go from a 2.25 60' to a 1.9 60' that is 0.35 quicker. then the improvement compounds as you get down the 1/4mile. I would hit a 13.5 easy. 13.4 is not out of the question. so from a roll if the driver was any good you would be even. and if the cobalt was slower something was wrong or the mods were really not on the car or this is just not a true story at all.

By the way I love your car (just because it is a 350Z).

later.

 

i dont understand how you won while you were in 2nd at 25 our cars a pig at 25 in 2nd

 

Dude it is a time slip. My 60' ('=foot) was 2.25 seconds and with Drag Radials (DR's) I could get 1.9 seconds in a 60'. that is 0.35 seconds quicker in 60 feet alone. that multiplies. 0.35 seconds is easily 0.5 seconds in a 1/4 mile. now with my current setup I go 13.9 seconds. with the Drag Radials I could get it down to the same time as the modded 350z. With that knowledge I questioned what the real truth is about the modded 350z vs. Cobalt SS/SC with GMS2 story. Is that clearer now. sorry for the confusion there.



I was #43. see the other time. same as me pretty much but a 1.9sec 60'. the other vehicle was a truck with dr's RWD with some power and more weight, but I played catch up with less weight and likely more HP. The driver stated how I would have wiped his backside if I had tires like him. and he is right. He only trapped 93mph to my 101mph. that is 8mph better with the same 1/4 time...LOL I could reasonably get 108 and go faster. look at 350z MPH trap. his car gets out the whole better but from a roll I would take him and leave him behind up to 100 for sure. you can see that I have a stronger car cause of the trap and times. He only did 103. there is more in my car too. my best trap is 102.5 but a bad start caused my time to be higher than my personal best. If our cars were able to get out the hole better I would be able to beat 350z. from a roll I definitely could beat him. I wish he was in my area so I could prove it to him if he doubts.

He may only have a few bolt ons and is N/A. but were a little 2.0L that is faster from a roll than his 3.5l with a few bolt ons. there is no argueing that displacement is king. we all know that. but come on man. look what were bringing to the table. a $23,000 car with $1000 in mods and were faster than your $45,000 car with what ever else you spent (this is in Canadian dollars). To be this competitive for the money I say is pretty good. You have an awsome car though and I would buy it. be proud but be real.

 

nice kill man. i tried to race one from a dig and i lost both times, hence the loss in my sig. i have never raced one from a roll. i should try some time.

 

I have not either. I never said I raced one. the other vehicle on that time slip is a drag truck with big slicks.

as far as 350z my encounter was stock for stock from a light (assumming the 350z was stock) the car took me and then it was dead even to 50mph.

I am just showing how a start is important to your 1/4 times and comparing these times to 350znal's time in his signature. with the right tires we could be as fast as his car out of the hole which would equate to being overall faster in a 1/4.

 

Trap speed is a better indication for roll on encounters than ET. The guy in the 350Z above is trapping a couple mile per hour faster than yours, so I would still expect him to pull slowly on your SS, all else being equal.

 

Your right but your not looking at the numbers. He is RWD. I expect his 60 to be 2.0 or better. 1.9 is highly likely as seen on dragtimes.com. that allows him to do 103 in a 1/4. I almost do that in 1/4 with a time of 13.9. if I get my starts to 1.9 I will trap more speed and my 13.9 will be the same or faster than a 13.4. I would expect faster.

A colbalt that did get 1.95 60' trapped 104 and 13.35 as found on dragtime.com.
http://www.dragtimes.com/Chevrolet-C...slip-8644.html

Here is a 350z with a similar time as 350znal

and mine

can you not see that 0.35 second start difference would equate more time for my car to generate more speed trap and in the end a faster 1/4. 2.25-1.93=0.32 that would be 13.96-0.32 = 13.64. 13.64-13.4?= 0.24. the 0.24 would easily be taken up in my better start. I have had countless people who experienced 0.5 sec. taken off there time with the right tire.

keep in mind I did not say I would kill him but I would pull away a little in a roll or stay with him at the very least and I wish he were here to prove it. IMO anyway. and it is backed by numbers as I have. if you see the #'s differently that is ok.

 

Oh I agree, a few tenths or mph here or there is no biggie - can be down to differen weather conditions. track elevations, etc. BUT 60' time has little, if anything, to do with trap speed. Actually I find I usually trap a little higher with more wheelspin/poorer 60' time.

Main thing is to have fun and respect the other guy...it's all good!

 

true I have had faster traps than 1/4 times but that proves to me I did better on the later half of the 1/4 than other my personal best 1/4. that way I know the car can go faster if I put the whole 1/4 together. If I had my perfect reaction time, the best 60' of 2.18 and the best 1/8, best 1000 foot I would be at 13.8 or 13.7. I know the car can do 13.8 for sure. just with a different person behind the wheel or I continue to learn. I brought this car from a 14.3 to a 13.9 with practice and 20 runs to get it down. there is more to a 1/4 than a 60' you have to put it all together. YOUR TRAP TIME IS AN INDICATOR of whether you car is capable of going for a faster e/t. if you trap faster on a slow 1/4 then imagine what the trap would be if you put a good start together.

I have shown respect all along. I have said I love his car, I would buy one, and displacement is king - always. where did I show disrespect? I have lots of fun.... thanks.

Taken from the link above see these times it would appear slower e/t vs. faster trap speed all the time but the fastest trap speed does not have the slowest E/T.

Run, R/T, 60', 1/4, MPH
1, 1.192, 2.642, 17.663, 77.31

That's what makes going to the strip so much fun (and a challenge) IMO - getting everything to work just right...launch, shifting, tuning - to set new PB's. Even though there's always a car in the next lane, I find in the end you're always racing yourself to get the best run you can out of the car. And as you've pointed out, driver mod improves with practice and is the most important factor of all! Drag racing? I just fackin' LOVE it *L*!

 

see my edit to last post.

and yah your right. I just use my slips to find where I can improve. I remeber shift points etc. I wish I had a computer to monitor all that to have a better comparison of what my inputs were and wheel slipage and stuff. I do have fun. comparison of slips from other cars do not dictate what your car can do but it is out of more interest sake.

 

LS1Tech.com is a great website - used to spend a lot of time there when I had my '98 WS6 Formula. That's where I first leaned about a neat little item called AutoTap - allows you to log all your runs so I could compare shift points/speeds/ frorm each run and save them to a log file to pick apart later when I got back home. I don't know if they make a version for the Cobalt, but it's a great little all round tool that allows you to capture all kinds of various data to be used for tuning, drap strip, etc.

P.S. here's the product website... http://www.autotap.com/

 

OK.. now my input as to what has been said. SS you are somewhat on the right track as to breaking down a timeslip... What you are failing to see is i am getting to 103 at 13.4 secs(on streets) and you are getting to 101 at 13.9 secs. In a 1/4 mile that would equate to about 2/3 cars easy. To lower your track time and get the mph takes more than just driving. The better you grip the lower the mph. The more you spin the more mph you have. If you ran a 1.9 60ft on dr's vs your 2.2 You may get to a mid 13, but your mph will be around 98/99 vs that 101. Here is one example. I tried dr's and got a 13.3@102 and street tires i got a 13.4@103.69. I lost mph, but i ran a faster time only cause i hooked up better.


Your trap speed is a indication of what you can run. With you running a 2.2 60ft 13.9@101. If you hook up you will probably run 13.4-13.6@98-100 max. There is alot of stuff that plays into this factor. I've been racing at the dragstrip for about 7 years. I've had my share of fwd and rwd cars.

Just something to think about.


As to 45000 car.. Not quite. I paid 26k for mine and put 600 into it when i was running the 13.4's... Now i have 3800 or so in it and hoping for high 11's.

 

Think about this. I will show you my time slip when I am done. Tires street tires that grip. then I will show you what another 1000 will do.

oh buy the way. there is no way my car will do under 100 in a 1/4 again. Your right about the car lengths, but that never was part of the discussion. I am just saying my trap will be higher and my E/t will be better with traction.


Either way my car right now will pull just as hard as yours with a roll or out pull you. But lets leave it alone. your not driving up here to meet me for pinks or something.
the 45000 was a quote of what the car runs new in CANADIAN not US. US it is like 35000 or so. but now your comparing your used car to my new car which I paid new for $23000 canadian or like under 19000 US or so. I am still way under your used car.

edit: read this post from another thread. I see this all the time. Our cars a bad out the hole but after that LOL .... just read on.

Nissan 350z Vs. Cobalt SS/SC

--------------------------------------------------------------------------------

so tonight a buddy and i were out crusin around in his 2003 Nissan 350z and we come across this 2006 Chevy Cobalt SS/SC (victory Red) and so we get goin on the high way just messin around and the guy turns around and we follow and he rolled his window down and asked if we wanted to race and my friend was like ya so we do the 3 beep and go and the 350z was pullin on him off the line then we got in to second gear and the cobalt ss starts passing him and at about 130 the ss has about 3 cars on the 350z. after the race we meet up at walmart parking lot and we talked a little bit and the Cobalt was bone stock just got it not to long ago. and my friends 350z has an intake manifold, k&n intake, exhaust and a new computer. my friends reason for loseing the race was cause his clutch was bad but when they guy with the cobalt said it was bone stock u should have seen the look on his face!! haha

*********= your cobalt . com

 

, I cant believe you took your time to write all this to me thats sweet , but if you read you will see that no where in this thread was i talking to you , read my ONLY post (other than this one) and then read the original story , now after all that i hope you feel like a real bad ass READING> you

 

For your trap to be higher than what it is now and run a better time. You will need to either shift differently or make more power. From your current slip you posted. To go any faster in the 1/4 you will lose mph.

Also if you look at your time slip. You will look that after the 1/8 mile you gain 21.4mph. That is average. The 350z slip you posted does the same 21.4mph. So there is now pulling that car down. The jump he gets on you he will keep or get wider. The z has better aerodynamics. You can't compare one persons run to another. There is always a better driver, better circumstances, motor is broken in better.


You will see to go faster in the 1/4 you either make more power to gain mph or go faster and lose mph. Btw.. My z stock did 13.8@102.7.. 1/8 was 8.8@80

 

Well I have written to you once. and that is because you did not quote who you were responding too. I could only assume it was to me for your post came right after mine. so YOU SUCK AT WRITING and READING as all my other posts were in general and to 350z. And the orginal story has nothing to my posts.

I believe it. but it is RWD. it is not comparable. and your coparing time slips when you say you cant compare time slips. I think you can compare time slips to a certain degree. as far as aerodynamics I would like to see the coefficient drag data you have to support it. I am not saying your wrong but it just seems like a nothing comment.

and as far as time slips go it looks like the cobalt GMS2 can keep up with a modified 350z from a roll then. thanks for pointing it out. and I said it will keep up and may pull on it. either way it is a mute point. the cars are very close at a roll and I would love to get rubber and meet to go for a friendly race.

and final point please dont take my comments as "the cobalt is the fastest car in the world why dont you own one" cause it is not. it is an economy car, not a performance car. but as a economy car it is pretty impressive. I will be the first to say a 350z has alot more potential, but this was not what were currently discussing.

 

well the coefficient drag on a 350z is .31 which is the same as the corvette. Research yours and let me know what it is. That does play a role in interstate runs. As does tranny gearing, final drive and hp/tq.. As i had stated before though, i took down a gm stage 2 balt with a intake on the interstate. Like i also stated you can't compare one car to another.

 

not going too. why? it doesnt matter in getting a 1/4 time as you stated. I know my drag is lower than stock though. We can compare cars though LOL I have the same MPH from the 1/8th as 350z that has similar time.

this is going no where. so where do you live. I may be driving to florida so if your on the way (going from ND down south). only way we can put an end to this but you have to have the same setup. doesnt sound like either of us will. I have alot of parts sitting on the counter for my econobox.

later displacement king.
