WoW can you believe this?!?!?
 

I just got back from Englishtown Raceway in NJ. this is the second time i hit the track since i got the G. I broke into the 13!!!!!!!!!!

Second run of the night
R/T____ .346
60' ____ 2.183
330____ 5.985
1/8 ____ 9.071
MPH____ 80.50
1000 ___ 11.711
1/4 ____ 13.938
MPH ___ 99.58

i scanned the slips just to show that the times are legit. i was in the right lane all night and was number 824.

sorry the quality is bad. had to use low quality to get the image size to fit.

Very nice. You'll only get quicker. 6MT I assume?

One thing that's odd is your ending trapspeed. You're only gaining 19mph in the last 1/8 mile which is a bit slower than average. I would have expected 101mph traps if you're a 6MT and are getting 80mph in the 1/8. My 5AT is getting 21.5mph in the last 1/8. Oddly, my 5AT is trapping about .8mph faster on average than my friend's 6MT sedan.

What are your shift points? Are you decently quick with the shifts?

yes its a 6mt. and i shift at 6500 rpm, but on that run i hit the rev limiter in 3rd. and yes i am very quick at shifting. lol or atleast i think i am.

Thanks
Jay

Nice!!
You got in the 13s 3 out 4 times with only intake and plenum?

I was actually going to go to Englishtown on the same day as you with my 05 6mt but something came up :(

i have never been there before but it was a very nice track. if you are interested in going up again soon i think i will prob go to this. http://www.my350z.com/forum/showthread.php?t=125746

Thanks
Jay

oh and sorry yes i got into the 13's with only plenum and pop charger

Thanks,
Jay

I fail to see how its impessive when you have it modded, isn't bonestock brealy off 14? like 14.1?

well if your not impressed, then find someone else that is running as fast or faster in the 1/4 mile with only plenum and intake.

Thanks for the support,
Jay

Actually 13.93 is pretty impressive. Keep in mind that those magazines are using professional drivers to track 1/4 mile times, and 14.1 is the best time out of many runs that they got. With only a plenum and pop-charger, he has knocked off 2 tenths of a second.

jblade - what rpms do you launch at, 3.5k?

i launched at diffent rpms each run just to get the feel for where to launch. and i have come up with launching at about 1,500 rpm or 1,700 rpm. the reason is because the first time i went the track i launched at 3,000 rpm and had to much wheel hop. however i did run a 14.2 like that. and i found that if you launch between 1,500 and 1,700 and ease off the clutch just enough to get traction and then dump it that you will have a better 60'. but thats just the method that i used to get the time i did. keep in mind this is only the second time i have been to the track in the G.

Thanks and hope this helps,
Jay

Thats pretty good. Condsidering you don't have very many Performnace upgrades.

cool. i live like 5-10 mins from raceway park!

Congrats! With a good driver and ideal weather dipping into the 13's can be achieved.

Hmm....I'll try the 1500-1700 rpm launch the next time i'm out at track.

My first time at the track with the G, I was hesitant to launch anything below 2500rpm thinking this would produce slower times and traps but noticed too much wheelspin and crappy 60fts in the process. I didn't think launching at daily driving rpms would produce better 60ft times?!

BTW, congrats getting into the 13's!

Nice job! I wish I lived near that track. It seems as if all the best Z/G times are coming from that track. Me=Jealous...

Dang . . . ZOOOOOM! Very nice runs. Keep it up.

thanks for everyones support. i think i am getting my A.A.M test pipes installed on thursday and going back to the track friday. however my kintex plenum broke so it looks like i am gonna see how the car does without it.

Thanks,
Jay

sorry kinetix*

How did it break??? I am beginning to think the Kinetix plenum is not very durable. On my350zforums, someone's Kinetix plenum melted! What is up with this Kinetix :confused:

the coolant block on the back of the plenum broke and ripped my coolant lines. but they are sending me a new one. the performance of the plenum is awsome. and it sounds great. i had to put the stock one back on and now i had not having the kinetix on.

Hope this helps,
Jay

13.9 @ 99mph is pretty sad with all those mods
 

Nothing against you personally. I just think it's sad that we (yes I have a G35 Coupe, a 350Z before that, and a 300ZXTT Stage IV before that) can spend $2000-$3000 on aftermarket parts for our cars and get basically nothing out of it. I mean come on, I've seen stock G35 Coupes run 99mph in the quarter mile, and your telling me that with all those mods the car is basically just as fast as it was stock. That just kills me. I was just at the Stillen day and watched a bunch of 350Z and G35 Coupes on the dyno and with the exception of the forced induction cars, the results were pretty sad (when you take into account how much you spend on a $1200 exhaust, $250 spacer, $150 intake, $150 grounding wires, $600 T-square ECU, $500 cats). I guess I'm just venting my frustrations with the aftermarket companies. They need to come up with some better products. The only car that impressed me was a kid with a red 300ZXTT with a few bolt on mods. I talked to the guy and his car was similar to my old 300ZXTT. He put down 401hp and 450tq and spent about the same as I did when I modded my last 350Z.

I agree with much of what you said, but some of these mods you listed are questionable when it comes to adding true useable power. That's why you don't see huge gains on the track or on the dyno.

1) $1200 exhaust. I haven't seem any reliable third party dynos that suggest that Stillen/Borla true dual exhausts add anymore than 5-7whp. Lots of people swear they're faster, but added noise greatly increases the sensation of speed. My G feels quite a bit slower than my old 96 Maxima because the G isn't remotely as loud as the Maxima was with a y-pipe and intake. On the track there's only about .15 difference between the Maxima and G. According to my butt dyno, the G feels well over .5 seconds slower.

2) $250 spacer. Spacers truely do add useable power and seem to be one of the better bang for the buck mods. 8-10whp across the powerband is pretty substanial.

3) $150-350 intakes. These are a total waste of money on the G/Z. The stock intake already flows more than enough air plus the location of the intake and the design of the intake path are ideal. The system pulls ambient air from a high pressure zone of on the car. Why mess with it. If you want more sound, add the Z pipe. Intakes are purely noise makers.

4) $150 grounding wires. Grounding wires don't add power. All they seem to do is improve shift feel and throttle response on the 5AT.

5) $600 T-square ECU. The ECU adds a useable 8-10whp across the powerband. Not exactly one of the better bang for the buck mods out there, but it does work and doesn't increase noise or affect driveability.

6) $500 cats, $350 Y-pipes, $250 UDPs. Total waste of money and it blows my mind people invest all this money in mods that have proven time and time again that they don't add anymore than 0 to 3hp. The stock cats flow fine. This isn't the 1970s. Catalytic converter technology has progressed to the point where they are not restrictions in the exhaust. NA dynos constantly show that a cat is about a 1-2hp restiction. On turbo cars that flow a ton more air, the cat does become somewhat of a restriction, but not on NA cars. In the 1970s and early 1980s, the cats would suck out 15-20hp. Not now. Y-pipes are worthless too. The stock pipe is ugly and does have some crimp bends, but these bends are not enough to cause a restriction on a 260-300hp motor. Ugly doesn't necessarily = restricted flow. The debate will never end for UDPs, but every dyno I've seen for the VQ shows the UDP makes 1-4hp of which the average gain across the powerband is 2hp or so. With a set of cats, a y-pipe, and an UDP you'd be lucky to see 7whp and an average powerband gain of 4whp. You'd get more of a performance gain out of running 15-16lb lightweight 17s.

The 350Z vs 300ZXTT comparision doesn't apply. Forced induced cars always stand to make huge gains in performance with minimal money. That's the hard truth. $500 in an 03/04 Cobra results in a 60whp gain. $500 in an NA G/Z gets you 10whp. If you want cheap power, get a turbo/SC car.

The hard truth is the G/Z VQ35 is well designed. There isn't a whole lot to improve upon. You can gain ~15-20whp with $800, but after that it's going to take quite a few mods. Honestly, if people would stop adding heavy and wide 18+ rims to their G/Zs, they would get significantly better times. Everyone seems so concerned about performance yet they add heavy and overly wide rims to their cars which hurts acceleration, ultimate handling numbers, braking, and ride quality. I'll never get that.

i also agree with what is stated above. however i think the plenum, pop charger and z-tube helped me improve my 60' a greet deal. but who knows for sure. i also agree that the G/Z was designed extremely well, and yes aftermarket mods less turbo or supercharger show minimal gains.

Thanks,
Jay

It depends on the track and outside conditions at the time. Me and a 04 G were running constant trap speeds of 97mph, both stock. There are people who can run 99mph stock, but the track will have a big factor in it.

the track conditions seem to be a huge key in drag racing.

Jay

like its modded" I see some very good driving here. Understanding that drag racing a 3475 pound car that is geared for almost 195 mph. The driver here has done his job. Great job.

i think we deserve those numbers.
it's like making 10sec civic with less money into it.
since our car is more expensive than other cars, we deserve to put more money into it to bring out the true power of G.
if you wanna blame everything on someone else, you should consider yourself to get a civic. i bet you will see better numbers just by putting money on what you've already spent on your G. (around $40,000?)
some of you just dont understand the connection between G and its numbers.

Back in tha day...
 

:o This is not like the "old days" of the Detroit Vee eights, a poor design that could be easily improved apon with a few "bolt-on's". Those old motors had restrictive intakes and exhaust manifolds, poor valve trains, push rod motors that were (in stock trim) limited to 5500 RPM. You could bolt on a new high rise aluminum intake, a new carb, some headers and a low restriction exhaust. and get 50 HP easy. You would spend no more than $1000 for this. To get 50 HP more from the VQ35, which has Over head cam's, four valves per, smooth straight intake runners, and fuel injection, with "bolt-on's" is damn near impossable.

congrats great times

thanks everyone for your support hope to see you all at e-town raceway this weekend.

Thanks,
Jay

Actually to see how big the improvements are for him he might have gotten his times for doing the 1/4 without mods.

Then the times with mods.

14.1 is with professional drivers and ideal track conditions.

Even though Jay is running 13.9's his track conditions might not be ideal nor is he a professional driver. For all we know he shaved a full second off his bone stock times.

Until you go FI or huge mods like that you are not going to see 2 and 3 seconds shaved off your times. Maybe 1 second or 1/2 seconds at a time if you are lucky.

Nice work though Jay. :)

i consider myself a descent drive, not a pro. i guess we'll see what times i put up this weekend. Hope to see you guys there.

Thanks,
Jay

I have to say, impressive, but you need to work on that launch. You should be able to get that 60' under 2.0 that would be awesome. get it down to a 1.90 and you will see some big numbers.

Great job and good luck.

Yes, you are a pretty good driver to be pulling decent times with your car with a few mods. There is no telling how many runs the professional driver did to get the 14.1 times with the ideal track conditions. :)

You will get better with more runs.

Congrats on a nice run!

Oh, and Dave, looks like you had some stuff to get off your chest, lol :) Good post...although I feel that my G is signifigantly louder than my 95 maxima, weird...

IMO, it's impossible to get below 2.0 60' NA. I've never seen it done...ever. That's on a G, of course.

If you like that you'll love this thread Randy.

oh boy!

I bet a g35X with a stillen superchager and about a 3200-3500 stall would get 1.9 60ft

I think 1.9s on 17" drag radials would easy for the 6MT sedan and 2.0s should be fairly easy to come by on OEM tires with the right track prep in the 6MT. The problem is we have a lot of "green" racers in here who think dropping the clutch is the way you get done the 1/4 mile the fastest.


I'd think upper 1.7s would be possible. 350Z autos are pulling 1.9s stock. A G with a lot more power and a heck of a lot more torque multiplication should be able to do a lot better then a 1.9. Sounds like a fun ride to me :D
