Within 2 weeks im buying a full mevi kit and JWT ecu from a org member for 900 bucks. (Crossing my fingers I dont get scammed). I Did order a mid-pipe from frankencar.com about 2 weeks ago and STILL WAITING for it to come. My question is with these mods how fast will my car be:
(95 5-speed with 102k miles)
-Stillen intake
-frankencar midpipe
-MEVI
-JWT Ecu
-Stillen y-pipe
-Gready Cat back
-Performance cat.
-Light wieght 15's with street tires
-Stock clutch with about 10k miles on it.

I want to shut up a couple of kids at school who think there 4 bangers are fast. All of them claim to do 14.5 and this modded sentra on spray does 13.8 So I want to know if I would be able to beat these kids.

 

This is the ALL MOTOR forum not the bolt ons forum. And again, why in the world did you WASTE your money on a mid pipe?

 

Thread's been moved.

Has the midpipe been proven not to help?

 

first you ned a shortshifter and upgraded clutch kit. then you need a lightweight flywheel and pulley. the cat wont do anything for ya .
hope you got it lowered with springs and shocks.you wont get the sentra unless you supercharge or

 

Those Sentras are no joke when properly done .... they can haul ***.

 

I am lowered. KYB/AGX. Thank you for moving this topic. IM SORRY if I didnt know where to post it. I know I need an upgrade clutch kit. I have put my car on a dyno once and It said I would run a 14.3 on the 1/4. Im guessing with the mevi and ecu I should be at 14.0. No spray for me, never will do it. From what I KNOW, that sentra has a JDM motor with cams, a header, and stright pipes with the whole car gutted out. He wanted to race my friends trans-am but backed off maked up excuses put spray on his car over the weekend and blew his motor. He has a nice crack in his tranny but says it will do nothing but leak fluid and racing it wont do anything to the case. He's a shady person. Anyway I think he would race me without spray. Im guessing he will end up with a 14.2 car without spray. Makes sense now?

 

you will be fast as lightening.

Why don't you look in the 1/4 mile time data base and see what others with those mods are running

 

Sentras are nippy 4 bangers, but I personally think they are ugly.
Its like driving a fast soap around, with no luxury.

 

About the sentras, aren't there tons of them with a crapload of mods and all they can run is like 14.9? I remember seeing a thread before showing a list of them with mod lists that go on forever and the fastest was barely in the 14s?
Stephen, on a N/A car it's a waste of $30. I remember there being a thread with a dyno and the guy had lost like 1ft/lb and gained 1hp and I don't think there were gains under the curve either. I also remember someone, a business owner or worker, come in a and say they replaced the cats on an ARMADA with midpipes and they lost somewhere in the neighborhood of 30hp or ft/lb.

 

You could run in the high 13s but I think it's far more likely you run in the 14.2-14.4 area.

 

Wait a minute. Are we talking about intake midpipes or exhaust test pipes?

 

With those mods, assuming your car is running well - - low 14's are likely if you nail the launch and shift very well.

 

the man said he is running 14.3 after dyno if you add cams,fidanza flywheel, clutch, pulley, mevi,and jwt ecu you should be doing mid to low 13's .

 

With those mods you should be in low 14s (possibly high 13s but very tough) with a good launch and quick shifts. Get them at the track after you get your mods. Don't just tell them "They said I would run 12s" or whatever. That doesn't mean much.

 

I did 2 runs on a mustang Dnyo jet in my school. I didnt care about my hp and tq yet because I didnt have a mevi and ecu installed. Both times from a stand still It said i would run a 14.3 Dont forget its inside a school building, hot air all over the place, Im sure if it was outside the numbers would be lower. Its winter time where I live the dyno jet corrected its numbers but still isnt as accurate as if It was outside on the road with temp. at 23. Im sure with a mevi and ECU I will be 14.0 or 13.9 with a new clutch I will be 13.9-.8 all the time. Im not bluffing up a storm I may not be as popular as these other guys on the forum but sure will be after I start posting slips. (Thats when I get everything and get them installed.)

 

I would put very little stock in what the dyno told you+. If you want to know how fast your cars is then take it to the track

 

I will once I get everything. I dont doubt the dyno at all.

 

Of course you believe it. It's telling you that you will run low 14's with an intake and y-pipe. I bet if it told you low 15's you would not believe it.

So with your present mods, which I am guessing are intake and y-pipe, the dyno told you that you would run a 14.3. Then you say that outside with colder temps you would run lower....say 14.2. So you are claiming to have the fastest known intake and y-pipe maxima ever....without even going to the track


Have you ever been to the track?

 

Bro can you read?
-Stillen intake
-frankencar midpipe
-Stillen y-pipe
-Gready Cat back
-Performance cat.
-Light wieght 15's with street tires
-Stock clutch with about 10k miles on it.

I got a lot of other mods but has nothing to do with the speed of my car. Yes im lowered KYB-AGX's/H&R. I dont want to be ignorant, I do trust dyno times. It was AE corrected. No im not bluffing up a storm I dont have a magical intake nor a 200hp y-pipe. Enough said. And No I havent been on a track Have street raced with 14.0 cars that ran on the 1/4 and I have beaten them. Closed street racing Im not stupid to race on a highway with cars around me. Like i said Just because im not AS known As other org members doesnt mean im going to be proven wrong When I myself Know what my car does. This thread is just for me to know IF i will hit high 13's which im sure I will.

 

Did you actually weigh your car for the dyno results, or did you guess?

 

I removed everything from the trunk which was pretty much the spare tire and audio stuff. That was a good 300 pounds lighter. Then left the car pretty much as is. I dont know how heavy my car was after that. I do have after market rims, they are heavier than the stock steel rims with hub caps. I do have a GXE base model. Im sure all 95-96 maximas weight in about the same thing.

 

Don't you have to put in a vehicle weight for the dyno to estimate the 1/4 mile time?

If you didn't actually weigh your car, the results it gave you are meaningless.

 

I think what people here are getting at is: *IF* you were to take ur car to the track AND run low 14's consistantly with ONLY the performance mods u have NOW. (the ones quoted in this thread), you would probably hold one of the fastest n/a maxima 1/4 miles times. Can you see why some of us are skeptical?

 

From all that I recall, One teacher was setting up my car strapping it down to the dyno, another one went under the car to check for leaks or anything else that might be wrong. That same guy was looking under my hood for god knows what. I kept turning my back away from them to talk to all the students that came out from their classes to see me dnyo. Im guessing one of the teachers checked it, I wasnt paying much attention intill they told me to check around my car like as in the straps to see if they were tight and to hop inside my car and let warm it up by going up 2 3rd gear normally and letting it coast to a stop. Then he showed me the screen where it shows the track lights, once it hit green I took off. did the run 2 times and called it a night. I didnt want to run it again.

 

Hmmmm So yes, I can read. You don't have one of the mods your listing. Ordering a mod is not the same as having it on your car...and a mid-pipe won't really do anything but that is a whole other discussion.

So you have intake, y-pipe, and cat-back. and are claiming that you can run lower than a 14.3....yet have never been to the track.

So your beating 14.0 cars...so why are you not claiming to run 13's right now? That would be about the same as claiming to run less than a 14.3 because you did it on a dyno wouldn't it?

It's not about being "known", it's the fact that your car will not run that fast period. Nealoc187 ran a 14.4 w/ a 2.18 60' with those mods.

Stop with the ricer math and post #'s when you go to the track

 

WTF?! 1/4 mile dyno? since when can you run the 1/4 mile on a dyno? I'm really ****ing lost here guys. does it factor in arodynamics and drag or something? I dont know if i should laugh or choke someone......i thought dynos measured HP/TQ only.

 

yup thats right mike, you know everything and im just a kid that knows jack s h i t about anything, and that the dyno was 100% wrong and your compairing my car to someone else, when it all depends on the driver. Nothing is ricer math. I expect more Respect from you, concidering you are 25 years old. Im not going to Get into a fight over the internet because its worthless and im more mature than that. Ive never seen another car forum where people rag on their own fellow car members unlike this forum. There is no respect for anyone here unless your a "Big dog". I got nothing to prove to you guys, this maxima forum is suppost to be like a big family and not being a b i t c h to everyone because of what they post or say im doing RICER math. Thats uncalled for and you should be more professional with replies. I will continue to respect everyone as I see it, I still think your replies were uncalled for, and shows me that you have no respect.

Take care

p.s. admins can delete this thread because I dont want people to start a fight over nothing.

 

You can do 1/4 on dyno's if the dyno is programmed to do so.

 

Just post some slips then they will get by u... go to a track and do a run there cause the traction on a dyno and track is different, plus u got aerodynamics issues and air temp... does the dyno take those things into consideration?

 

Just go to the track and you will find out

 

dyno 1/4

your missing the key element's here
part of your cars performance comes from the driver
going to the track trying to turn fast #'s
instead of assuming with unreal comparison

 

i agree with post #31. lots of things to consider but the main thing you want to do is to spank those 4 bangers. hit the track, make some passes, then challenge those guys and introduce them to the VQ, lol !

here is a nice reference:

good luck

 

My car has 339whp and 285tq - what will it run in the 1/4 mile?



Sorry guys - I feel like post whoring tonight....flame on.

 

Nippy 4 Banger Sentra? The car is gutted to nothing with Drag Radials. The dude thinks he is a super duper driver but has broken motor mounts and a cracked tranny because of all the wheel hop. How good of a driver is that? I'm the Trans Am guy he pussed out too... he's a *****.

Yes, a Mustang Dyno will tell you your 1/4 time if you run through the gears. I have heard of several cases it gets within .1/.2 of the real track time.

I have read on this forum by plenty that an intake and y pipe do wonders for this car.

Why WOULDN'T a mid pipe help? His intake right now is severely restricted by another filter, why wouldn't a straight pipe replacing that add more suction which in leighmans terms would... create more powah!!

A 14.0-14.1 should be very feasible with a MEVI and ECU with his supporting mods I think. Why is everyone ragging here?

 

14.0-14.1 is possible at a good track in good weather with a good driver and a good run, however the likelyhood of those four components coming together all at once for a person who has never, ever, even been at a track, are slim.

He is getting ragged on because he thinks that dyno #s equate to 1/4 mile numbers, and refuses to acknowledge the fact that there are people on this board with actual track experience (years of it in some cases) who know that this is not the case. He keeps saying "I know what my car will run, and you are all wrong" when the guys who actually know a little something about track racing, are saying "don't be so sure until you actually get to the track."

A dyno can't take into account the most important part of the 1/4 mile, the launch. Especially for someone who has never launched their car on a track, this is the wildcard. His car may have the power to run a 14.3 under perfect conditions which I don't doubt, but his chances of perfect conditions on the track together with a perfect launch, are pretty small. A mediocre launch can turn a potential 14.3 into a 14.8 or worse.

The moral of the story is, don't claim a 1/4 mile time until you have a timeslip showing that time in hand. Until then you are just assuming, and you know what they say about assumptions.

 

And what "other" filter is this one? You must be reading the 4th gen forum too much. I weep for you.

It is feesable but that is not what we are talking about, at least not me. What I called him on was running a 14.2 with an intak, y-pipe, and cat-back. Without ever making a 1/4 mile pass in his life he suddenly has the fastest maxima.

The worst thing to do is get on this forum and start claiming times that have not happend.

 

One other factor your leaving out is your car reacting with track conditions. The rotational mass of your wheels along with wind resistance and reaction time. Wheel spin and deff your launch. None of us are here to tear you down. Instead we are expressing the unknown variables that can only be equated at the track.

 

Yes a large part of it is driver skill. There are a couple of NA guys on here who are in the high 13's...theblue I know of for sure, and I dont think he has a MEVI either.

 

I think 1/4 mile is stupid at least for the most part. I like to see that 4 banger top out right as you pull hard on him. Granted its not safe but ive gotten borred of drag. Not bashing anyone that does like it.

 

Haha, maybe he took out the spare and subs then subtracted that 300lbs
from the base gxe weight to get the low numbers on the dyno.
