Wow, I actually never looked at the date! I will admit that I am a dumba** for adding to this thread that is that old.

tx77015ls1 must of searched for LS1, then replied to this thread.

 

Wow this is old. I just looked at that...

DayblueZ got down to 13.1's now.

 

Ya, whats funny is, I saw his name, and I saw his time posted in this thread, but I knew his car was faster then that. Like I said I just never really looked at the date. Not a lot of people bring up such old threads in the drag section. Usually that was an issue in the street racing section, but thats another story!

 

Leaving a second before your oppononent is called a red light....

 

LOL, wow, this is old. Damn Ray, i saw your times. 12.1 that's great . Zach only managed a 12.8.
Yea, my auto does just fine.

 

Pu t a turbo or even a supercharger on your car and you can put him in his place.

 

Same could be said either way.

 

I had a MT 99' SS and ran a best time of 12.823 when it was still bone stock to the paper air filter. But there's a lot of factors that come into play with any car. Altitude, driver skill, air and car temperature, even the tolerances held on the engine and drivetrain components when they were produced (which is why some cars can be naturally faster than some others that are exactly the same), among quite a few other things.

I haven't taken my stock MT 07' Z to the track yet, but I know my SS would've smoked me off the line (60' times were like 1.8xx on stock tires). However, I've raced several SS's at high speeds already, and much to my amazement, I have left every one of them at least 10-15 cars behind me by the time I hit 150+. We ran about even from 70-80 up to 95, but when I hit 95 and shift to 4th, I just start pulling on them like mad. I run about even with my friend's 99' vette at high speeds (same engine but has 350 hp stock, 18k miles and just a K&N in it so far). But he'll start to overtake me after 145-150 mph and also has a top speed of 178 mph, so not a chance for me. Maybe I'm a good driver, maybe they were poor drivers, maybe both. But either way, my new Z is performing well beyond my expectations and I'm even happier now than I was the day I bought it.

 

10-15 cars?? You know that's rediculous to believe they were still going... speed limited at 160mph and without the limiter a stock LS1 Fbody will see a few ticks over 170mph... If a 350Z had better trap speeds I could see it maybe pulling a length or two up top but 10 - 15? HA

 

Actually, they are limited to 157 mph, I should know, I owned one. And believe what you want, I just know what I've seen. I seriously doubt any of them were modded in any way, and the drivers had probably never been to a dragstrip either. I don't even know if they were MT or AT. Also, if the 07' Z is running low 13's in the 1/4, why's it so hard to believe that at high speeds it will pull on a SS? The Z isn't a dragster, it's a top end sports car. Which means it shines in the top end, not in the first 1/4 of a mile from a dead stop.

Edit: Forgot to add... The B4C Interceptor (Florida State Trooper Camaros) have a much better performance package than a stock SS and aren't limited, and have only been clocked at a top speed of 168 mph. Since you're so keen on the Camaro, there's some trivia for ya.

 

wow, you're a bit on the hostile side?

 

FWIW..several different sources site the limiter different and not one of them has 157mph listed... Edit: Number is Officially 160mph as verified by a tuner a few moments ago. Also...a B4C does have the same speed limiter as verified by several B4C owners... unless the department that owned it had it removed it's still in there.

The B4C package from the factory was not any more powerfull than an SS (the fact that you said this definately amuses me as well.. I bet you think a Z28 is significantly slower than the SS) unless someone added something. Not to mention added weight and a few items that create extra drag. They only came with 1LE components and a heavy duty alt. I would be curious to know...was the b4c you mentioned clocked with a light bar on top? I actually went to 171mph in an Auto LT1 with just a tick over 300rwhp. Since the LS1 actually had slightly better Aeros and more rwhp it isn't hard to see 171 happening.

Also the fact that I've seen 1 car run a 13.3 I still have to comment that the MPH is NO WHERE NEAR what an LS1 car can produce running the same ET (AKA top end is not as good).. LS1 cars rarely see better than a 2.1 60ft so it's really a matter of horsepower.. granted your aeros are better (.31 vs .34) but thats a lot of horsepower to make up for.

I will sit back and wait till I see summer times posting up before I comment more.. but you guys are getting way to excited over the 07s.

 

I don't know what sources you're looking at, but my 99' SS cut the fuel at 157 mph and you definately knew you hit the limiter (not like the Z which just won't go any faster).

Here's a direct link to a sale of a B4C on Ebay, directly from the people that purchase them from the troopers here in Tampa. It has all the specs on the B4C listed, but sadly the pictures are gone due to the age of the listing (I lost the bid by $100 at the last minute ).

you will also notice as you read that it clearly says, "the Camaro is the fastest production Police car around, the car has been clocked up to 168 MPH stock." I would say that "stock" is un-modified, wouldn't you? Meaning that it's not limited by the same limiter as the rest (if limited at all).

Also, how do you know you went exactly 171 mph? Using the speedometer in another car that's with you, or guesstimating using the Camaro is not a very good gage at all. The accuracy of any speedometer is questionable at those speeds, unless it's been clock verified at those speeds.

What do you mean a lot of horsepower to make up for? The 07' Z is rated at 306 hp, and from what I've seen and read this is clearly underrated. For the sake of it, let's just say it's 315-320 hp at the flywheel. The SS is only 330 hp at the flywheel. Then there's other factors like the aeros as you already mentioned, drivetrain loss, weight, not to mention that the Z has a 7500 rpm redline which means that it can go to faster speeds on lower gears (since higher gears require more power this would also give an edge at the top end). Plus the cars I raced might have also not been running at peak performance (they are 5+ years old you know). 1/4 mile doesn't tell you as much about top end as you think. Look at a Lambo, their 0-60 times aren't that impressive considering their power, and neither are their 1/4 mile times. But it'll go over 200 mph with ease, and much faster than most cars which will smear them in the 1/4. There are so many factors which can come into play for this that I can't even think of them all (and really don't want to).

We can argue this all day, I just know what I seen. Regardless of why or how. But I was also doing 155-160 mph at the time, I only glanced at the mirror. It could have really been 6-10 car lengths, I didn't look long enough to try and count them. I was more concerned with what was in front of me than what was behind me, if you know what I mean. But I clearly seen them through the rearview mirror, and they weren't in the same lane. They were also right along side of me when we hit it (which is how I know for a fact that we ran even until I hit 4th gear at ~95 mph, and started pulling away at about 1/2 a car length per second). Some of my information may not have been 100% correct, the only things I am 100% certain of are the limiter on my SS and the fact that I have looked at 3 SS's in my rearview mirror so far, since I seen it with my own eyes.

I think you're just stuck on your older Z and don't want to admit that the new Z's are a big improvement on the top end. Either way, I know what I've seen and I will continue to put the Z to the test. I'm done with this argument since it will lead nowhere in the end except for a waste of my time, which I have little to spare. I hold no grudge against your opinion, you are entitled to it, as I am to mine.

 

My sources are from HPTuners... I spoke with Keith at HPTuners yesterday and he confirmed that every 98-02 Fbody has a scaler value equal to 160mph. I myself have seen quotes all over the place from 159mph to 162mph.. the only thing I can figure is the scaler value has a +/- % offset of a few mph (which means your 157mph may have been correct now that I think about it...but then that means other cars can reach above 160mph as well.)

This was also another thing that I spoke with a tuner about as well as 3 owners of B4C cars that post on LS1Tech.. the factory limiter isn't removed for the B4C option which means the one in question may have been stock... but someone at least removed the limiter. As far as my other comment about the aeros being affected.. I see this one had the spot light deleted but they commented about holes drilled for lightbar. My guess would be they are quoting a magazine review or michigan police test report. I can't exactly shoot that into the dirt without knowing if they had a good source but knowing tuners and owners of other factory B4C cars have stated the limiter is still present I have my reservations.


I will admit that it wasn't clock verified via radar...but simply calculated based on engine RPM and gear ratios (which as far as I know it a fairly solid base). Just shy of 5400rpm in 4th gear with a stock gear 4L60E and 3.42s out the back with factory tire spec.


The reason I stated this is that (you should really know this) the LS1 fbody was severely under-rated and makes roughly 300rwhp vs what I've seen from the 350Z cars (260rwhp I think was the highest Ive seen and it was a new 07) not to mention torque differences... thats a difference of 40+rwhp you have to make up somehow. With the corvette we actually dyno slightly higher due to their higher parasitic loss through IRS.. in their case we are just up against their much better aeros (.29 vs .34).... against you guys we have more power and worse aeros but a corvette with close to equal power and better aeros doesn't easily slip away from us until well past 120mph and even then it's by a few car lengths in the end.

I won't fault you for your experiences... I have a lot of time spent north of the 150mph mark as well and years of experience dealing with F-Bodys... Being part of a Chicago Fbody group and having access to several very well respected tuners as well as guys who have years of experience to enhance my knowledge.

I am not stuck on my older z (I have no idea how you guys can skip over this time and time again)... I honestly didn't know Nissan had a Z car in 1995... and after looking I laughed at the fact that you thought I believed it was fast at all (If that was my basis for giving you any grief I'm surprised you didn't just come right out and call me a moron)

You have my respect for keeping things civil... but I am going to retain my initial stance... a 350Z pulling a stock Z28 LS1 past 100mph by multiple car lengths??? It's a stretch to say the least... maybe that's been your experience (who knows what really went on)... Just knowing that 01 ~ 02 Fbody cars put down 305 ~ 315rwhp (98 ~ 00 cars seeing 300~310rwhp) and seeing the newest 07 350Z stick down 261rwhp tells me unless we have a major driver issue this isn't going to tip in your favor. The math just isn't there.

 

Bolt on Z versus bolt on WS6 T/A.

VeeTec - ??? LS1s have made 12 second passes stock... .the bolt on Z ran 13.1... Extremely pointless vid without more info.

 

rsx is still....ah nevermind.

 

There are about as many LS1 F body's that have run a high 12 stock as there are Z's that ran 13.6 stock.

Here's the same WS6 T/A, which had a few bolt ons.

My point was that it's still a drivers race, when the 04 Z has a few bolt ons

The 07 Z is plenty fast enough to be a drivers race stock, and for the record, I recorded LS1 kills with my stock 04, which we all know ran a 13.6 stock.

I still have to get the 07 to the dyno, but I have seen 07's dyno in the 270's completely stock. 261 rwhp would have to be one of the lowest yet, which can vary from dyno to dyno.

 

I'm not going to continue debating this, and I have no way to prove what I've seen. But there are a couple more things I want to point out which you should take into consideration.

5400 rpm in 4th gear = 171 mph. If this is true, then it clearly shows that the SS is turning a higher gear ratio somewhere in the drivetrain than the 07' Z, and that's going to eat a lot more power than the Z's drivetrain. In 4th gear at ~7500 rpm I'm running at ~145 mph (I'll have to get more concrete numbers this weekend, but these are very close). That's a very big difference in gearing. 2100 rpm less and 36 mph more... As has already been shown with the NSX, raw power isn't the end all be all of racing.

I've been a seasoned driver since I started going to the drag strip in 2000 with my 99' SS. I 'thought' I knew how to drive until I started going there. When I first started going my best time in my SS was in the high 13's (like 13.7xx). By the time I'd done about 10 runs, I was hitting the low 13's. Since then I've beaten cars time and time again that 'should' have beaten me, and also hit a best of 12.823 while still stock. I seen you say somewhere in a previous post, that most LS1's get 2.1 60' times. Well I was hitting 1.8's repeatedly on the stock radials at 30 psi in the rear, and a slight burnout to warm them up (after the water box). I launched at around 3000 rpm. MT too (in case you were wondering), I refuse to own an automatic sportscar. Takes the fun out of it, and some of the driver skill. This was also done at Gateway International Speedway near St. Louis, which is a pro dragstrip, so the timeslips were 100% accurate.

I wouldn't put myself as being as skilled as the pros, but I'm no slouch. I can't see how driver skill can have much effect over 100 mph though (unless it takes you 2-3 seconds to shift or something). I'll have to get out to Desoto Speedway here near Tampa soon to see how my Z runs, just so I have something to post to show how well I can run it. I was guessing it was a low to mid 13 second car (13.0-13.5) before any timeslips were even reported here (to my knowledge), which I stated in another thread here over a month ago. I've never been out there though, so if anyone here goes there, could you give me some info. Like what night(s) test and tune is, the times it starts and ends, the price to run, would I need a helmet or other gear for a hardtop Z, etc...

As far as being civil, I see no reason to not be. Not everyone is going to agree about everything, it's just a fact of life.

 

... That was actually with the 4L60E 4 speed Automatic (2200 built trans using stock ratios, kevlar clutches, 2200 stall, shift kit, manual valvebody, etc)... The top speed was limited to 181mph due to the lack of extra gears and ratios especially with the LT1s 5700rpm redline. On my LS1 6 speed 5400 in 4th gear is only 111mph. FWIW.

Don't sell yourself short you are actually a very skilled driver.... and I would never question that (which also means you could easily beat most drivers no matter what they were driving; obviously with exceptions like a 10sec car vs 13 sec car) I've actually beaten a few Terminator Cobras in the area but I still realize that their potential is superior to what my LS1 is capable of and respect that.

Once again this shows you have a lot of skill... in fact Evan Smith of MM&FF (who has run 12s in multiple showroom stock F-Bodys at E-town) has done so with 2.1 60ft times.

According to what you have posted you have actually matched what the pros do... I would say that puts you up there.

Good luck with this and let us know how you do.

World needs more people like this.
