1/4 mile times seem off

[mean green s14]

ive read from a couple people on these threads that they have ran 14.8- 15.0 with the nsport stage one kit! i know theres lots of variables but that cant be right, nsport claims 240 hp at the wheels with there stage 1 kit, lets just say for some strange reason you only make 240 hp at the crank! you should still run better than a 15.0 or even a 14.8?lets compare to a 1988 mustang gt 5.0== 215 hp and about 300 ft/lbs==3200ilb and they run 14.8-14.9 all day long, 1997 240sx nsport stage 1, 240hp==and lets say 260ft/lbs==2860lbs,lined up side by side at the track they would run the same 1/4 mile time i dont think so!!! i know alot depends on the driver and other variables but a 14.8 seems high. i guess what i would like to know is what is the average 1/4 mile time acheived in a 240sx 95-98 with the nsport stage 1 kit????and while we are at it whats the meaning of life???

sorry for rambling on and on im just curious.

i bet its the tyres, as someone else said, they lost to a srt-4 due to traction problems. I hope once my turbo is installed it will pass somewhere into low 14s, hopefully high 13s... ah even if it doesnt itll still be very cool and faster than a lot of other cars out there.

[mean green s14]

yeah but going by the numbers and weight they should run high 13,s mybeee the low 14,s but a 14.8-15.1 is way high i think!

[WDRacing]

There are far to many variables to compare 1/4 mile times with different cars, with or without the same turbo kit.

1, Does the driver slip the clutch or drop the clutch?2, What tires, what compound, what pressure?3, LSD or not?4, Weather and elevation?5, Time between gears, speed shifted or not?6, What suspension?

Thats just to name a few of the big ones.Even dyno's can very by large numbers.

yea i was dissapointed last week at the track my best time was 14.8 at 8psi,nsport stage 1. with my auto and stock motor i got a 14.3 and that was with no spark after 4500rpm. but then i realized i have lower compression and 3psi less now. also i couldnt launch at all, when i tried my clutch slipped terriblely i got a 24 and 25 sec 1/4 that night. depends on a lot of stuff

[Nebraska240sx]

true that is weirdwould expect better?

me too

[mean green s14]

i know theres a billion variable but my 97 auto with i,e,pulley,and nsport stage one should run low 14,s to high 13,s i would hope.i mean think about it an extra 100 ponies to the wheels thats way more than a stock jdm s14 and thats about a 14.8-15.0

[mean green s14]

i guess ill find out when the track opens up this spring. but i guess eitherway it will be a whole lot quicker than most cars cruising around here!

[Structure240sx]

yea on my best run that night, again with a horrible launch like 2.4 60' i beat a yellow 5.0 mustang that thought he was fast. he finished first but his reaction was .1 while mine was .5

[Imissmyturbo]

Lets not forget that differnet engines will put out different hp depending on it's compression,carbon buildup, and state of tune. You can't claim that you WILL make xxx amount of HP if you slap on this "kit" with "these" parts with out any tuning. But also track conditions, suspension setups, and driving skills are all variables.

[HIGHLIFE]

your time has a lot to do with the track itself some tracks are just crap. plus everything that WD said. it was my first time racing at the track, i'm sure with more practice it will get better. i'm boostin 5 psi and got the 14.crap. but i had fun so thats all that counts for me

[3rD GeAr]

i finally took my ka24et powered 240 to the track in carlsbad, ca. my best run of the day at 11-12psi was

Reaction--.987 60ft--------2.256 330ft-------5.920 1/8 e/t-----8.938 1/8 mph---82.33 1/4 e/t-----13.698 1/4 mph---101.77

that was with an open differential, 195 passenger tires, and stock suspension.

[mean green s14]

dont get me wrong a high 14 is still fast ,i just think with the amount of hp a ka24de makes with any of the turbo kits available that a s13 and s14 chassis should run in the high 13,s on 7-8 psi

[SingleCamSam]

If you can pull sub 2-sec 60' times you can do low 13's with 240whp.

[tony/ka24de]

I ran a 14.69 at 8psi. But the turbo spools up fast and dies down to 6psi after 4500. So when I'm running the 1/4 there is only 6psi.

[HolyShiznit]

If you can pull sub 2-sec 60' times you can do low 13's with 240whp.

Yes and no...........http://www.nissaninfiniticlub....25365

Orion is at mid 13's with a ****ty 60' so I bet if he would have dropped it to a 1.8 or even a 1.9 he would be at maybe 13.1ish. And his is an S14 that weighs about 2800+ pounds.

But ya with 240whp I expect to be doing low 13's for damn sure.

BTW: singlecamsam, I do agree with you, with 240whp you SHOULD be in the 13's easy.

[lbrowne]

Just for reference on how important the track itself plays into your 1/4 mile:

The track I went to for the first time had me SO angry as to why my times were so high. Untill I took a breather and went into the stands to watch other carss I was like, wait a minute, I'm right where I should be based on what these other cars were running....

LS1 F-Bodies, normally a low to mid 13 sec car, were getting low to mid 14s. My LT1 was pulling mid to slightly high, (14.6) on the same track.

The track is 3500 feet above sea level and also the air density/barometric pressure or some craziness according to the performace shop that frequents the track said theres times the rtack effectively is like running at 4000-6500 feet above.

Granted if I never had my bling bling 18s on and some drag radials on my stocker 16s, my TA would have been neck n neck with those faster LS1s. I beat a 2000 SS m6 twice, both of which were my fastest runs my best 60' was like 2.3!!!

My car at sea level would probably net mid to high 13s (without those 18s of course )

[lbrowne]

oh and my TA prolly weighs a hefty 3600 pounds with those 18s if not more....makes like 290hp to the wheels

[mean green s14]

right now i have a 97 s14 240sx , it has intake,underdrive pully,header,apexi exhuast,plugs,wires,and safc, and its an automatic, i run 15.8-15.9 al day long,i recently got a nsport stage 1 kit but have not put it on yet, its winter in st. louis 33 degrees.im just hoping i dont put this kit on my car and go to the track and run a 14.8 or 14.9,with the hp the kit makes "-(APROX.)-" 240 hp at the wheels i should get a high 13 or low 14.1-14.2 in the quater mile or somethings wrong! nsport 8 psi~240 hp at the wheels~13.9,thats almost a mathmatical calculation. right?

[TachyonS14]

If you run it at the track and are not happy with the kit, give it 2 me :-P My 97 would enjoy a turbo.

[DaveEEE]

I believe my best with nsport stage 1 was 14.6 @ 98mph on horrible tires. That was about 7psi.

-dave

[nikn]

hey daveEEE looking at ur mod list... how much psi you running now? Any times with ur current setup?

[mean green s14]

how much hp to the wheels were you making with your nsport stage 1 kit?

[C-Kwik]

Keep in mind the NSport Kit uses a T04B. It spools nicely but is a bit lacking from a standstill. Turbo cars tend to be a bt harder to launch as it's hard to get a turbo to spool without a load. So typically you will launching the car with little to no boost. Bigger turbos are worse.

http://www.speedworldmotorplex.com/calc.htm

Use this calculator. Dave's car would be estimated at 220 HP at the wheels assuming 3000 lbs car with driver. Be more wary of the trap speed. It is a better indicator of HP than the ET.

[Structure240sx]

my car makes basically no boost in first gear. i believe its because i have a fidanza flywheel and 11lb enjuku driveshaft so there isnt too much load ont he car. i kinda like it tho on the street i can launch very well with no wheel spin. the track that i go to tho is very sticky makes a lot of people bog on the launches which i did

[SloS13]

Im having funky track problems too. I pulled a 14.1 a couple weeks ago at 7psi with crap clutch and open diff.

Now ive got a VLSD, stage III clutch and 9psi and best I could get yesterday was a 14.6!! I think its all about the weather. I need some alcohol injection

[Structure240sx]

thats really weird but makes me feel better about my times

[mean green s14]

im hoping for a 13 sec run

[mean green s14]

is it possible

[SingleCamSam]

13's are POSSIBLE with only 200whp (S14), but that doesn't mean you'll run them. Chances are, if you haven't been to the track that much you will be dissapointed in your times. Practice, practice, practice. And if you don't want to look like a novice on the line, find a nice deserted road to practice your launches and perfect them. Look at Greaser on FA, his S14 runs 12.80's with only 250whp. It's not because his car is special, it's because he's a damn good driver!
