Alright, I know it's not the coolest thing in the world to post street racing results on the org. But I just have to share this with everyone!

So it's late Friday night around 2am and I just left my friends house after helping him lower his car & installing a stereo system. So I'm tired as hell from being up early & just want to get home & hit my bed. Well my friend lives out in the middle of know where & some guy in a like a 99 or 00 Cadillac STS pulls up next to me & keeps trying to get me to race with with him. I wasn't worried that I didn't have a good chance to beat him or anything I was just tired & was having a difficult enough time keeping my eye's open. So finally after about 3 or 4 times of him gassing it & letting off I make the decision to see what he's got. He had some D&D muffler sticker in his back window & it sounded like he had duel flowmaster's on his car. So we end up stopped at a red light, the light turns green he takes off slow & I do the same. I guess he got the picture that I wasn't gonna race with him, so he floors it my guess to just get where he's gotta be. So the minute he floored it I nailed the accelerator pedal, he had about a 1/2 a car length on me before I hit second gear. Once second clicked I pulled about a car length ahead of him & was holding. So then we get caught at another stoplight, I flip the switch to open my nitrous bottle, the light turns green, we take off, I wait until I'm in second gear then hit the gas & leave his *** very badly. I wish I could say we had a chance to stop again so he could ask me what I got, but we couldn't because I must have been atleast 15 cars in front of him when he had to stop for the red light I just missed. If I would have had to chance to tell him what I got, I would have said something like 15hrs of sleep to catch up on. Anyway, thats my weekend kill story. Don't worry fella's I don't plan on posting anymore of these, because I don't want to hear any crap about how street racing is illegal or anybody else's nonsense. I just though, you all wouldn't mind hearing about how some moron though he was the ish, but found out the hard way that there's always someone bigger & bader on the block...

 

so..what do you have?

 

ooooh thats my best part. yeh keep it safe but nice kill those sts are no joke.

 

very nice gotta love the spray... i want some

 

My Max is equipt with,

INTAKE
Injen (CAI)

EXHAUST
Custom Y-pipe w/ 2-1/2" downpipes not pre-fabbed
3" Flex section / 3" hi flow Random tech. Cat
3" B-pipe
3" inlet ES creations straight thru muffler

NITROUS
35hp NOS dry system
nozzle is placed 2ft. from throttle body
AEM adj. fuel pressure regulator

TRANNY
Automagic
Drop resistor mod
Hayden #403 trans cooler

Also, I just put on a set of 18" Nissan Murano 5 star rims I picked up off ebay for $100. I think I might have beat the STS even worse N/A if I had my stock 16" SE wheels with 215/50/16 tires. I did notice quite a loss in performance when I went to the larger 18" wheels. My auto is suprisingly quick off the line with the stock SE wheels & 50 series tires. I'm happy with it, the car is plenty fast for me. Besides it's my daily driver, not my track star.
Ya, those STS Caddy's are quick. My pop's used to have one & it was deffinitly no joke. If I remember correctly the advertisement for the STS back when my father bought his was how a STS Caddy could spank a Corvette. I'm not sure, but at the time the STS was one of GM's fastest production vehicles for the year. I think it was 1993 or 1994. I have to say I don't think I would have got him if we had started from a dead stop. But since we were rolling when we got on it I had a better opertunity while driving N/A. Once the bottle became a factor, there was no contest.

 

Wow, 3" exhaust? What the hell for? Sounds like you're actually proud of yourself that you beat a car cause you used ***** juice.

 

Big D don't rain on his parade. A wins a win. Good job...must of been lovely to pass him. His face must of been priceless.

 

Sorry Big D, I don't see what your trying to get at hear. If you read carefully you will see how I bested the STS while driving N/A & then destroyed him once the bottle was on. Anyway, the statement I was trying to make has nothing to do about bragging or anything of that nature, but how idiot's out on the road don't know when to call it quit's. I appologise is my post was confusing to you, I tried to explain it to the best my knowledge can allow.

 

Isn't a 3" exhaust setup recommended for boosted setups rather than 2.5" to accomodate the additional exhaust being generated by the engine?

~THT

 

Why don't you say the same thing to Jime since he used nitrous to run his 12.1 when he had the 4th gen...


Oh ya...to the original poster, a 3" exhaust is completely unnecessary. Even people (with some sense) running over a 100 shot of nitrous don't resort to that wide an exhaust diameter, let alone your relatively puny 35 shot.

 

Thanks Takentomax, I wish I could have seen his face also. But it was very dark, his window's were tinted & it was hard to see inside his car. Thanks for the support, I have a hard time making post like this, because some people have a hard time with post like these. For what reason I don't know! I actually don't have a problem with street racing, as long as it isn't taken overboard. My idea of a street race is 2 people, 2 car's & some open road. Not 500 people standing on the track drinking alcohol & testing the limit's of immaturity.

 

At the track! That's where it should be used. I also doubt he ran that with only n2o and if he did it was a 100 or 150 shot. I guess I'm the only one that feels nitrous is like cheating. Oh well.

 

I'm sorry if my 3" exhaust is becoming an issue here. Maybe it's my old school opinion that any kind of back pressure is a very bad thing. I hardly think that using a larger exhaust will do anything to harm performance.

 

Big D,

I feel the same as you do about nitrous. I'm more of a person that would rather accomplish lower 1/4 mile times N/A. I only have the bottle in the car for day's like the one I was trying to explain above. I basically have the bottle in the car to check people when they step out of line. Hence the 35 shot...

Also when I said standing on the track, I was refering to the side's of local streets. Not the actual Drag strip. I appologise for the misinformation.

 

nice kill. I'm respresenting in my area. So far i have a dozen kills just in the past 2 days and i have people talking about maxima's like they are the newest BMW's

boost does a body good

 

You, my friend, need to read this article...

http://www.magnaflow.com/07techtips/faq/question10.htm

edit: Errr...it's not really an article

Thanks for the article. I read it very carefully & it seems that my 3" exhaust is still ideal for my setup. Please check the chart they give you to refrence you cubic inches & horsepower my requirement's are 2-1/2 to 3". Beside, I still have excellent exhaust flow. If you were to stand behind my car & put your hand in front of the exhaust tip it pushes the exhaust gasses extremely well. you can probably feel the flow out the tip about 4ft. away. Thanks again for the info, I always appriciate things like that. You are deffinitly a friend...

 

Actually IIRC 0 backpressure is bad. You need some kind of backpressure. I bet you that if you dynoed your car with a 2.5" exhaust vs the 3" you'd probably have more power with the 2.5".

 

If anything I would probably show alittle bit more low end torque. But on the mid & top end I bet the 3" exhaust has bigger gains.

 

^ Don't you think if that was true everyone would have a 3" catback? I don't even think it makes a difference since you have a 2.5" y-pipe.

 

You are correct I don't think these that big of a difference between 2-1/2" or 3" exhaust. It was just my prefrence to go with 3" exhaust, especially since I made a bigger then average Y-pipe. All I am saying is I don't feel like my 3" exhaust is hurting my performance. And if it is, it deffinity isn't worth replacing my entire exhaust system for maybe a 1hp increase?

Reminds me of Gone in Sixty Seconds. "Go Baby Go"

Nice kill.

 

Aftermarket y-pipes are ALL 2.5", except the 3" WS has.

 

I'm sorry but I think all the aftermarket Y-pipes are only 2" from the flanges down. You may want to re-reseach that...

My Y-pipe is 2-1/2" from each manifold & go into a 3" collector.

 

i also read that article and now i'm a little sceptical. For someone pushing close to 300 fwhp, what catback is recommended? I have a 2.5" y-pipe and was ready to go 2.5-3" test pipe w/ resonator then a 2.5" b-pipe and a 3" inlet muffler (dynomax super turbo muffler). That test pipe, even though it opens and closes the exhaust, will that hurt performance? I guess i'm in a little bit of a different position since exhaust will produce more than the regular 5 hp people normally get...?

in other words, will i be fine with 2.5 - 3 - 2.5 - 3? If not whats recommended?

 

Had a run in with a G35 auto sedan last night too. well it beat me... but i was at its door to about 80 and then mine shifted into 3rd (big gear). This was on sR 37 by 75th street. The kid.. yes kid, was ricing around a little.. so gave the gurgly 3.0 some gas and he heard me. Light turned yellow so we lined up. I heard him brake torquing a little... but decided to keep mine as a normal start. But yea... i have a 195 HP 192,000 auto maxima and it was right with a 280 HP new G35? I coulda useed my y pipe then... but that is in tommorw.

 

Well the only thing I can recommend is to do what you want with your vehicle. One thing I would deffinitly avoid would be to have sections of your exhaust 2-1/2" and other sections of your exhaust 3". You should atleast maintain the same size pipe throughout the entire exhaust system. Excluding the Y-pipe. It's not like your gonna put 3" exhaust up by the flange's where the exhaust outlet from the head is only like 2". Just keep in mind that if you go with 3" exhaust now, if you ever plan on boosting your Max then you won't have to replace the exhaust later. Just do what you think & feel will improve your car & the end result will be your happiness???


Lude AEM,

Isn't it sweet to be able to atleast keep up with these high hp vehicles?
I swear people bug out when I blow past them & then the find out I'm an auto with maybe 165whp. Maxes are the sh_t........

 

G35 sedan packs "only" 260hp. Good job keeping up with it

~THT

 

your right THT... my fault. But i was happy i guess.

 

i think that big d has lost his mind by saying that back pressure is a good thing.... its bad, its always bad. you want to reduce it as much as humanly possible. aslo if he gets good flow with a 3" pipe then i say let him run it. i have yet to see a dyno where a max lost power by useing to big of an exhaust.

 

i still find it very hard to believe that the maxima kept up with the G35, especially when they are both auto.

 

Back-pressure is NOT always bad. How do you tune an exhaust with a usable 6000 RPM range without it? In order to maximize power in all rpm 'ranges' you need back-pressure. Yes, ideally, an exhaust system would not have any. But unless you are going to build a infinitely variable exhaust system, you need it.

So you beet a V-8, equipped with an aftermarket exhaust system, which has 300hp stock? Last STS I raced grossed me in every form of the word. Only place I could take him was in the corners. But I suppose with your 3" exhaust system lowering your performance and a "35 shot dry" you would be pushing somewhere around 100 HP over stock. (Considering you have a lighter car otherwise you would need about 160 to take him as you described.) Though, that is not even considering your trany oil cooler.

"I am not proud of my ego and I know it is not cool to post threads on maxima.org about egos. Let me tell you a story about how proud I am of my ego...."

Logic defies many

I do not buy this story. Many will disagree with me and say I beat :alce car here::. An sts would gross your max and you do not have to accept that.

Does being cynical make me come across an ***?

 

G35 Sedans and coupes both have 280 hp

 

nice kill fella's
it seems i cant race anybody without gettin pulled over and given a ticket. for example this past weekend when some jerk in a tundra floored it past me and then swerved over in my lane. so i gun it and fly past him of course and about 100 yards in front of him when a cop in the oncoming lane busts a u-turn and pulls me over. 130 bucks and 2 points later im pi**ed. oh and the tundra got away.

 

That chart has been around forever and needs to be updated. Most modern 3 liter (183 cu in) engines are making power in the 200-300 hp range these days, so I would ignore the engine displacement column altogether.

Back pressure is always bad, but in sizing an exhaust to maintain good exhaust velocity at low rpm you have to put up with some back pressure at high rpm. It's an engineering trade off. The best exhaust would be one with high exhaust velocity and no back pressure.

 

guys i have to say i believe him totally. my boy owned a 95 sts which i think was one of the fastest one they made. i admit stock that man used to whip my a$$ like i was standing still. but when i put a 60 shot of nitrous he couldnt see me. i was running 14.6 in the 1/4 with that shot,so i see it believable if hes in that range. also a bigger exhaust will slow down a n/a car in the 1/4 but will give great top end results. im talking from facts i had a 3 in exhaust on my car and it slowed me down a little cause they told me it helped fi people better which i didnt have at the time.so the question is what is the max's 1/4 mile time if you ever went to the track here is the sts 1/4
