Hey what should a 97 240sx do in the 1/4?
I ran a 15.9 best at 87 mph
My 60 ft was bad 2.4 - 2.5
Thanx

mrace240sx

Im no drag expert, but if your car is stock I would say those are #### good times.
Running a high 15 seems right with a stock 240sx and from what I know, 2 seconds is a great time for 60ft in any car, and you arent that far off with your stock 240sx.

I could be wrong but those seem like pretty impressive numbers, congrats <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

holy cow your car is radical.... just keep up the car and add on! and show up those honda boys

ditosx

I'm not sure where you live, but I live in Rapid City, South Dakota. &nbsp;The elevation here is 3300 ft. and yeah, it sux!! &nbsp;Anyways, I have the basic bolt-ons, Injen intake, custom 3 in. cat-back exhaust and Greddy header. &nbsp;In the 1/4 mile I run 15.4 @ 94 mph. &nbsp;I've done altitude correction and if the info I have is correct that's a 14.8 @ 99 mph at sea level. &nbsp;Just goes to show what a few bolt-ons can do. &nbsp;Keep it up and you too can whoop SI ass!! &nbsp;If you aren't already(I'm sure you are!)

That's not a bad time at all...I ran a 16.0...only ran one time though and even had the Injen intake on....nice!!

LanceS13

The few places I've seen 1/4 times for stock 240's put around 15.9-16.1...so that looks like a pretty good time. &nbsp;Good job :biggrin:

That's a f(bleep)ing awesome time. You sure your car is stock?<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'>?

Oh, and do you have an LSD?

Jeff240sx

Dito. &nbsp;Your altitude correction seems off. &nbsp;14.8 is blistering for a basicly modded 240. &nbsp;I have seen people with a turbo kit run 14.6.
I dunno. &nbsp;That is mindboggling.
-Jeff

Yeah, hello, how come I didn't catch that one? An exhaust and an intake CANNOT take you from 16.4 to 14.8-definitely!

RacNgi

My has a cone &nbsp;intake &nbsp;and thats it .
No lsd I wished sick of doing one wheeled burn outs

Wow. That's pretty dope. My boyfriend has a '96SE with headers, intake &amp; exhaust and an aluminum flywheel which all deliver power to the wheel. The best he ran was a 15.7. That's really good then <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>.

xLSTONEx

your b/f sucks at drive no offence but come on, but acctually the problem was probably the flywheel. On not very highly tuned cars light weight flywheels slow you down. Make your rpms drop down to much inbetween shifts and you lose all your power. He should have saved that mod till the very end.

LanceS13

I don't think the lighter flywheel would hurt times if you shift right...that is, shift quickly w/o fully releasing the throttle. &nbsp;It should help times by reducing reciprocating mass and parasitic driveline loss.

Exactly. It averages to about 10% more power output to the wheels. I'm thinking underdrive pulley is a little easier to install and does the same thing, but hey...
Nice use of English, Lance! <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

Thanks! I try;) :biggrin:

I don't know if it's been proven, but there's a possibility that a lightened underdrive pully will damage the crank shaft in the long run b/c of its lack of a harmonic damper. &nbsp;Don't know if it's true or not...but I personally wouldn't risk it for a couple of horsepower.

misnomer

Another thing about that 1/4 mile time, a car's power varies by altitude pretty significantly. Higher up, less air pressure, less air getting into the motor per stroke, less power, lower 1/4 mile times <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt=':p'>

RacNgi

well this time was at E-town in NJ

ditosx

Well, like I said I don't know if the altitude correction is correct. &nbsp;Even when the car was stock I never ran a 16.4, why did you assume that I ran that? &nbsp;15.7 and 15.8 were the norm when it was bone stock with a drop-in K&amp;N filter. &nbsp;I did forget to mention that I took off the clutch fan. &nbsp;But again, I got the altitude correction off of this site: <a href="http://www.prestage.com/carmath/NHRA_Correction_Factors.asp

So" target="_blank">http://www.prestage.com/carmath/NHRA_Correction_Factors.asp

So</a> I don't know exactly how accurate that is. &nbsp;But what is certain is that 15.44 and 15.47 gets me into the 15.4 club. LOL!

Jeff240sx

Lance. &nbsp;The problem with underdrive pullies is that it has no harmonic balancer. &nbsp;This is true. &nbsp;Also, the fact that our motors are serious strokers and above 2.0 liters makes a difference. &nbsp;The crankshaft wobbles from the &gt;2.0 liters, and is weakened structurally by the high stroke. &nbsp;Take off the only thing that is keeping the crank from doing bad things, and taking off weight that is a good thing to have on the end, and it is likely that disaster will occur. &nbsp;I have heard horror stories about ud pullies.
Then. in SCC a month or two ago, they had a project 300zx. &nbsp;They took off the stock pully, and put on an Unorthodox Racing under drive pully. &nbsp;Then they discussed the problems related to doing that, and somehow fitted a Fischer Harmonic Dampener to it. &nbsp;They claimed Fischer dampeners were made to keep Harley's from shaking. &nbsp;This supposedly cured the problem. &nbsp;And saved weight while maintaining balance. &nbsp;Possibly someone rich could try this out?
-Jeff

I'm really not ultra rich (otherwise, I'd have a '97 S14 with a turbo in it) but I'll start saving money to try that combo out. Somehow, I think Lance is right: it may not be worth the couple extra horses to the wheel. But I really like shopping... especially when it has to do with my car. Anyone who's actually tried the UD Pulleys?

misnomer

I remember somebody, I think West, saying they've used UD pullies for a long time with no trouble. . .

Jeff240sx

Sure. &nbsp;Lots of people have. &nbsp;But I believe this question came up, and West expressed that he knew about the problem, but hasn't had it happed. (Let me just say I don't like speaking for other people).
But... if you read up on 240sx.org FAQ, there are people there that have lost thousands of $$$ on a UD pully, and are now as adamant about not using UD pullies as I am about not using NOS.
But in the end, it's entirely up to you.

my240likenoother

i pulled 15.8 in the 1/4 with just bolt ons and i have 130000 miles on the bi*ch

custom240sx

I run a mid to high 14 sec 1/4 with 6 grand of all motor work. &nbsp;How can you guys say you run 14's with just bolt ons. &nbsp;Please be honest dont bs your times.

Wow! That's a lot of money for a 14-second-car. What'd you do to it?

ditosx

Yeah no sh**! &nbsp;Someone took you for an @$$. &nbsp;Six grand of all motor and mid to high 14's? &nbsp;Where do you live Pike's Peak? &nbsp;LOL. &nbsp;I'm kidding, but not about the six grand.

Jeff240sx

Yeah... I don't know what you did for 6 grand. &nbsp;I am assuming a lot of body work that you included in that figure.
You would only need about 220 hp in a 2760 pound car with a 240 pound driver (3000 pounds) to run mid 14's.
220 hp is easy to attain in our cars, and would run about half of that $6k. &nbsp;Unless it's canadian. &nbsp;I like the exchange rate there. &nbsp;I bought a burger, gave the cashier a $20 and got $35 in change <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>
-Jeff

Hey would those 20s work in the states??? (JK)

AJ

can you get to 220 hp without turboing?. &nbsp;U said half of 6000 meaning 3000, and turbo kits are easily that and more,, then you have to figure in install.. &nbsp;Just a thought, wasn't sure how u were getting that figure, let me know man, i'd love to get 220 hp in my NA 240 for 3 grand... or could i spend 1500 and get say,,, 180-190? &nbsp;that'd be real nice <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'> &nbsp;i just didn't think there was a way to get all that power wihtout turbo or boring our your engine. &nbsp;I want to run mid 14's. &nbsp;that would be the shit, you could take down some z28's if they didn't shift real good <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'> &nbsp;thanks again guys n girls,, -AJ
