Ok, guys look. Im not a pro in cars but im kinda interested in makin them go faster. I was reading though maxfaq questions about Y pipe. I noticed that this line "the combination has been dyno'd to produce 20hp at the wheels." about Y pipe.

1.
What is meant by saying at the wheels?
I know maximas 4th gen have like 195 horsepower.... is it also at the wheels or, dunno, at the flywheel?
how to convert horsepower at the wheels into like normal horsepower i got used to hear about?

2.
How fast are 98-99 Maximas in 0-60 (we talking about auto)? My friend got 99 camry and it takes him 0-60 in 7.5 seconds. I would really wanna beat him. Will the Y pipe and intake help me with that? Or will I need anythng else? Anything inexpensive and healthy for auto tranny?

Thank you all guys!=]

 

4th gens are rated at 190 bhp. Then there's drivetrain loss when that power is transfered to the wheels. That number of power lost varies. Some say it's a percentage, some point out that the number stays relatively the same when bhp grows very large. Probably some complex function. Also depends on whether the car is FWD, RWD, AWD. The losses typically stack up in that order. Auto's also experience more than stick, having to put the power through a torque converter. I think 4th gens are dynoing 160's or so stock. But dynos are unreliable also. Dyno on a different dyno, or a different day, and there's always that variation.
Same goes for track times, depending on conditions, driver, etc.
But you should be about the same as the camry. It is a 6, right?

Simply put, hp at the wheels is all that matters. flywheel hp, which is what you see in ads and listed at car stats, are the higher numbers used to sell cars.


It is all relative.

 

ok.

one: beat him at the track. I beat a 2k1 Camry V6 (1MZ-FE = ) 16.3 for me... 16.9 for him. The auto kills it.

two: horsepower is not cheap.

three: fwhp -> whp does not involve a static reduction. numbers vary across the board. if you really want to know, dyno. even then, it varies (humidity, temp, etc.)

 

Okay, up until the early 70's engines were rated in bhp,which stands for brake horsepower, which is power at the flywheel with no accesories, etc. Around '72 the standard changed to SAE Net, which is Society of Automotive Engineers. This is measured at the flywheel, but with all accesories, emissions equip., and exhaust installed. This is why you see such a huge difference in HP ratings from '71 and earlier cars and '72 and up. Finally HP at the wheels, is just that. Eveyone is right that results very depending on weather, etc. A good rule of thumb is to take the advertised rating and subtract 20% for an autotragic and 15% for a manual. Hope that helps clear things up. BTW: Y-pipe and an intake will have ur friends Toy eating ur dust.

 

oh ok, now i understand it, thank you!
Then what is the stock 0-60 times for auto 98 and what will be 0-60 time with extra 20 horsepower at the wheels?

Camry 99 is the fastest year of that generation and they have 7.5 0-60......... will i beat it?

omg... i have the greatest idea!

You'll beat it..the Toyota that is.

Just go find out...at your local track.
If you lose, I doubt you will, you'll know what to do next time: work on your racing, add the a y-pipe+intake.

 

can you like compare maximas 98-99 0-60 before and after Y pipe and intake to camrys 99. 99 is the fastest year and they manage to run 7.5 in 0-60.
anyone?

 

you'll still beat it. ypipe? priabbly 15 flywheel hp? I forgot, wheres SteVtec with the dyno plots

 

comon now. you will own that camry. coming from someone who has owned both, the camry isnt even a match. i highly doubt it does 0-60 in 7.5 secs. possibly with a very very skilled stick driver. but they usually run 0-60 in the mid 8's. and quarter mile...well yeah nuff said.

the 95-99 stock max auto does 0-60 in about 7.4 secs. stick does it in about 6.8-7.0 now given a 1/4 and the camry will just get smoked. even a bad driver could beat a camry. im not saying they're slow, but by no means are they fast. thats why i got rid of mine. i needed something with some guts. hope this helps. be safe. peace out.

btw with a y pipe and intake your probably looking at low 7's 0-60.

 

v6 camrys of that year make slightly more power and weigh within 100 lbs of the maxima. Small enough difference so that options on the car, weight of the driver, and how much gas is in each car could swing the power/weight advantage either way. And the power curve of the maxima isn't great, drops off after 5500 rpm. The cars are damn near identical. 4 door grocery getters with a v6 and limited aftermarket support. After a pipe and intake, you should pull 1 car or so, depending on how far you run. But I wouldn't call it "owning" anything. Driving a 16 second car and showing no regard for other 16 second cars is the mark of a ricer. Also, don't worry about 0-60 times. Those are hard to measure and vary greatly from rag to rag. Bench racing is dumb, just go run the guy and find out.

 

ok....im pretty sure if the 99 auto V6 runs 0-60 in 7.5, and an auto max runs 7.6+, it will come down to the driver. i hate to blow it for you auto guys, but the cars are pretty identical. the V6 they have in those cars is pretty stout. things like maintainence, tires etc could make all the difference so make sure your car is running perfectly before you race him or else you could lose. i would get the y pipe before you race him so you have some room for error. practice torque braking, and take it to the track.
4th gen 5 speeds usually put down 160 at the wheels...so to turn that back to fhp, multiply it by 1.18 or so.

 

i dont want to sound ignorant to what you guys are saying, but honestly, coming from someone who has owned both cars ( i had a 98 camry v6), the max wouldnt have a problem taking it. yeah sure the HP specs are the same, but the toyota is not built for performance like the max. its a very smooth engine. i can honestly tell you it was sluggish. didnt have that UMPH my max has. and now with my y pipe and vbmod, the difference is day and night between my old camry and my max. peace out.

 

i hate max vs camry threads because they've come up before and went to over 7 pages. depending on the years, their specs are near identical. there was even a guy, glok, who ran a 14.7 stock if i remember correctly in his 5 spd camry.

don't make me pull up a link to that! too many people argue what they think and it just ends up being a waste of space with misinformation coming from both sides.

 

Maybe you just got a lemon, but the camry's engine is slightly more powerful. Not that it's all HP. You can have lots of power in a suburban but it's still not fast. Power/weight is what matters. Weight is real damn close too. The max is not built for performance either. Both are FWD with boatlike handling. Both have a 3.0 v6. Both weigh right about 3000 lbs. Rag times, camry forums, they all post about the same 1/4 mile times as a maxima, stock for stock in comparison. It's almost uncanny how much alike the 6 cyl camrys, maximas are. Those are designed to compete with each other, in the same market segment. The sportier side of a non sporty market.

 

point taken. maybe there was something wrong with my camry. either way, the max still has one up on the camry... its WAY more fun to drive and a hell of a lot better looking IMO! lata

 

MaximaTodd , what year camry did u have?

I had mark8 previously, lincoln... very fast but not reliable. I took 04 maxima in it heh....

 

i had a 98. (hated it)

...04's arent all that great. they are heavy beasts and a modded 4th gen could easily take it.

i got my *** handed to me once by a mark8 right outside my school in front of everyone. it was embarrasing.

 

Here's a dyno comparison of the 97-01 Camry V6 vs the 95-99 Maxima vs the 98-02 Accord V6.



The one with the yellow curve that's way above everybody else? That's the Camry engine. The Camry's "" 1MZ-FE engine is more powerful than the 4g Nissan VQ engine thanks to higher compression (10.5:1 vs 10.0:1), a variable intake manifold (Maxima has none), and two knock sensors vs one (lets them run a little more timing safely). If you drop a 1MZ-FE in a 4g Maxima, it would be faster with the Toyota engine than with the Nissan.

Yup, gLok (camry dude) was able to run a 14.7 with just an intake, which is just as good if not better than what most people are able to do here with their 4g Maximas. And I've seen stock times for the autos as good as 15.6, which equals the best stock times here for 4g's. The Camry is about 50-100 lbs heavier, but that's it. Auto gearing is pretty much the same, tire sizes comparable, and the mauals have similar gearing also. They're pretty much equal cars.

Our Highlander has a 1MZ-FE in it with VVT-i. For a 3900 lb AWD SUV with an automatic, the "" 1MZ engine moves that sucker pretty darn good. Better than the VQ in my Max could, or the J30A1 in my Honda. Go search in the 4g forum for the "old" Camry thread with all of the old-school guys arguing. There's lots to learn in that thread. If you're talking smack on the Camry, you're really talking smack on the Maxima too because they really are pretty much equally matched cars. Just the body is different and the badge on the hood.

 

That's news to me.

A few with 04's have run 14.4 stock with the auto, and one even ran a 14.2 with a dealer loaner car. It'll take a lot of mods on a 4g to beat that, and I don't think it'll happen "easily" either. Hint: the 6g is under-rated and most likely has a 350z engine in it.

 

I was waiting for you to jump in here. From those dyno plots it looks like the Camry has a good amount more HP and TQ than our VQ. So then why did the VQ win all those awards? I remember you saying you were gonna have a real in depth report on this at some point....is it done yet? We all think our V6 is so torquey, but the Camry V6 sure has a lot more TQ than we do

 

in depth report? haha...maybe someday

The VQ won (IMHO) because it performed just as well as the Camry V6 (due to being lighter) and blow the 1MZ away as far as overall character, smoothness and feel. The VQ begs to be revved. Not that the 1MZ is unrefined or anything, it just sounds dull and has a dull character. Toyota bland and boring, although very brawny for a 3.0L. The Honda is somewhere between the 1MZ and VQ in terms of all the "feel" stuff, but has by far the weakest torque of the three which results in the poorest performance. Despite having the highest peak horsepower rating.

 

Are you kidding me? Talk about the blind leading the blind. BHP stands for brute horsepower. The rest is correct but the bhp is not. Also, bhp is still the common measure of power for foreign cars such as Renot, Monero, Noble, ect...

Edit: I was having a brain fart and am totally incorrect in this statement.

 

Actually it's brake horsepower.

The thing in the 70's was gross vs net. Gross (no accessories, intake, not even exhaust) is about 25% higher or so.

And foreign cars are often measured in "kW" (kilowatts) and Nm (newton-meters) for torque. "bhp" and lb-ft are both English measurement terms, but the world is metric.

1 Nm = 0.74 lb-ft
1 kW = 1.34 hp

 

Yep. Thanks Steve. I was just falling asleep when I started thinking about it. I realized that I was totally wrong and got up to delete my post but you beat me to it. FNG, my apologies.

 

No prob, I've done it myself. Thanks to SteVTECfor pointing out the Gross vs. Net thing. Can't believe I forgot that!

 

Well said.

 

Didnt get a chance to race Camry yet, but raced in Mitsubishi Diamante with my friends' 99 maxima.

First race.
Mitsubishi didmante 98 with 2 people (the driver and me) and nissan maxima (1 person) started from the light. Both cars are stock auto. At first, Diamante pulled on maxima (like half a car) till second, on second maxima caught up, on third diamante pulled again. Race was till 60 then we had to shut down.

Second Race. This guy from maxima was racing in diamante, and me and my friend went from diamante to his maxima. As we hit the pedal, diamante jumps like half a car and nothing changes till 70 when the race was shut down.

Why Im saying this is that the day before i was racing mitsubishi diamante like 00-01 on my friends toyota camry 99 (the one im talking about), and camry took that diamante pretty easily and pulled on it like in 3rd gear. By 70 we were like more than a car infront of it.

:-\

 

mixonchik, your experiences mean very little. On the street nothing matters.

 

Street races don't mean crap. And since anything can happen on the streets, whatever conclusions you try to make about cars based on that are also "crap".

You can learn things from street races and make accurate conclusions. But you have to have a very scientific mind to be able to go back and analyze the race and the different cars to be able to figure out what really happened. That's beyond most people.

Go to a 1/4 mile track and then there's no question.

 

See Broan, VQ30DE = 10.0 compression...I wish it was 11.0...

Speaking of 10.0 compression, I still need to take you for a ride in my parents '03 5-speed AT Accord. It's loaded and amazingly nice. It will give you respect for Honda that you never had. Amazing interior and great engine (its ugly feminine engine bay notwithstanding). I'm sure my Max would kick it's *** off the line with my 5-speed MT and Y, but toward the end of the quarter-mile it'd pass me (until I get more mods). Thing is very powerful. 240 HP 212 TQ (haha, Honda torque still sucks), curb weight similar to a 4G Max. SOHC though, I wonder why they chose not to make it DOHC. SteVTEC?

 

Yeah man. Lets do that some time. The more you talk it up the more I start to wonder. A 3L vTec? Wow! Yeah I was totally wrong about the 10:1. Stuck my foot in my mouth with that egomaniac standing right there. And the Josh on the other hand was completely the opposite, I didn't get to learn a thing about SE-r's and was hoping he would demistify them for me. Also, I discovered my alignment is off badly so thats something I/we gotta do this weekend. Speaking of new cars with high HP, anyone heard about the new Acura RL. Its making 300 N/A HP out of a 3.5L. Now that is wow. But the article I was reading didn't declare if it would be RWD, FWD or AWD. I hope to god its not FWD. That would be the biggest waste of money ever.

 

By the time their top-end winds up a 4g could already be 2 cars in front of them, and you never get to 80+ on the streets. Yeah, they could run a 4g 5spd down in the 1/4 mile, but they're only pulling solidly once above 80 mph in the last 1/8th. The best stock times over at www.v6p.net are a bunch of flat 15.0's at 92-93 mph. But a 4g Max can do the same. Not bad for having a 50hp+ disadvantage.

Why SOHC? Because Honda is too damned cheap to design a DOHC i-VTEC head for the V6's and are content to stick with their SOHC architecture for now is my guess.

 

Wow, Maxima does kick @ss! 50 HP disadvantage, the Accord is only slightly heavier, and the Max still wins. I wonder why the Accord feels so fast when I drive it?
Although...I've only driven it once since acquiring my 99, so it may not feel so fast the next time I push it.

Thanks for straightening it out, Steve. Always appreciate your nice graphs.

 

The VQ gives you maximum thrust off the line but then dies slowly with speed and really starts crapping after 80. It's "quick" but not fast.

The Accord is the opposite. Weaker off the line but power and acceleration steadily builds with speed when you keep it hammered. It's not quick, but definitely "fast".

Both cars actually put down a maximum of 175 fwtq on the dyno. But the Maxima is a good 300 lbs lighter than the Accord is, and that makes a huge difference. That's reflected in those charts. Also, the gearing on the Maxima is more aggressive and that helps it even more. That isn't reflected there.

 

My bad, I was looking at the curb weight for the 4-banger Accord...the V6 is 3384 pounds in 2004. That's about right, the 4G Max feels way lighter. So yeah, good on the highway, "fast" but not "quick"
