Just wandering. Which is faster? An auto Max or a manual Max?

 

manual, no contest. i think its about a 1sec difference in the quarter mile.

 

I believe manuels are faster in all cars, not just maximas... Not for sure though.

 

for maximas:

5spd is faster because it has closer gear ratio than autos.

auto loses more drivetrain power due to torque convertor, that's why stock dynos on the autos are already lower than 5spd by a considerable amount.

5spd has driver's error whereas auto does not. a skillful 5spd driver is also a factor as well.

hope that help.

 

you guys are right about a stock maxima but just think about pro 1/4 mile drag racing. The auto is the choice of top drivers. No matter how fast and well you think you shift a manual, an auto is still faster and never misses a shift. Though the manual loses less power its not as fast under certin circumstances. jime and blubyu2k2 are great examples.

 

In my case for My 68' cutlass, manual was faster till i hit about 400hp then i built a full on race auto tranny and i got even faster. so i say Lower hp Manual is the way to go once you get higher hp i would say an Auto. But in the case of my old maxima being an auto i would say a 5spd is faster.

 

well that would be irrelevent since no maxima will be a pro drag racer

 

Automagic OWNZ all.
Don't you wish you knew the Magic of the Auto.

 

i think pro drags are autos because its had for the driver to control all that power and make the shifts at the exact right time with the exact right pressure.

Also, which car has the higher top speed? I thought one thing that hurt the auto vs the manual as the auto was gear lower which slows it does but gives it a higher top speed theoretically.

auto is better for drag or flat out track quarter mile racing just b/c of consistancy and the rule out of human error.. although a five spd trans allows more power b/c of the loss of the heavy tourque converter..

blake

plus>>> from wht i have seen on the org a 5 spd max has better gas milage then the auto... but i guess thats with any auto vs 5 spd.. ??

 

Auto maximas suck





Eric

 

what he said

 

I agree.

Although autos are good for fast hole shots.

 

dont hate on the auto's veah they can be slower but we will never miss a shift and with FI or nitrous we rule traction.!!!

 

Bullet proof auto with high-stall TC and VB OWN

 

Actually I have a stock one that hasn't been beaten yet in 60' by a modified auto or 5-6 speed.

 

agreed........

 

what happyricefob said^^^

 

blah blah blah. A 5-speed maxima still holds the record for fastest time


Enjoy your granny auto max

no matter which is faster, 5-spd is always more fun. plus it always makes a chick hotter if she can drive stick.

 

If moving your hand back and forth gives you pleasure let me introduce you to alternative sport.

 

hahaha,, autos rule

 

Another "5-speeds rule! No, autos rule!" thread...

Scoff-O-L

 

lol. i'd much rather have a free right hand than have to shift while in traffic, especially when my girls with me.

 

Both have their advantages and disadvantages. Stock the 5spd is generally faster. Modified, they can be equally fast. Consistency is higher with the automatic. If you want you could make an automatic transmission faster than a manual (faster shifts at precise points), however this would be impractical for everyday driving and nobody I've ever heard of has it on a street car.

Well I had both... My 95 max was an auto. I hated the fact when driving uphill, the transmission seem a bit lazy when down-shifting. Plus you need to deal with drive-train loss... You must remeber, that torque-converter robs plenty of hosepower. And that Sucked.. Yeah people swear by VB Mods... But its not the same as the five-speed.

So I then decided to convert the old 95max into a manual... Got a 5speed gear-box, quaife diff, act clutch kit, Fidenza flywheel, and short-throw shifter... Once I turned on the ignition and headed for the open highway, it was a WRAP!!!! The car corned better, accelerated better, decelaretaed better, brake better, shifted better, and redline better... Overall the whole dam car was better... Even the front-end seemed a bit different when cornering... Becuase the auto-tragic gear-box is about 40-50 pounds heavier than the manual... Weight tranfer was better with the 5speed.

But lets just face it... With 5spds, you have full driving control... Rev-matching gears under any circumstances is an advantage when it comes to daily street performance... This is what makes driving manuals fun...

 

I got a great deal on an auto that I couldn't pass up. Just because I have an auto I do not have misconceptions about it compared to a five speed though. Auto weighs more, has more loss of hp through the drivetrain, is hard to launch, has longer gears, and shifts slower with an inability to rev match as compared to a five speed.

It really depends on what your goals are. If you get a turbo and a built auto tranny I could see where you would could be faster. But for the average NA guy a 5-speed is the way to go. They are just rare and if your only goal is to beat up on most NA imports (ie: civics) a bolt on well maintained auto maxima will do fine. If you can find a 5-speed grab it.

 

D@mn couldn't of said it better myself.

 

How can you all bring up 1/4 times and all that BS when he wants to know which one is FASTER, not quicker (at least thats what I think he wants to know)....The auto probably has lower gears so theoretically it could have a higher top speed (I dont know if we have limiters or whatever, just got the car, still a newb :P ). The auto I got shifts hard and smooth so im not crying too hard right now.

 

stock for stock, manual is faster, but if u get 2 cars with the SAME whp, one auto and one 5spd, the auto wins.

 

thats what i thought he meant.

 

but you still have to account for the extra weight and shift lag on the auto.

 

Not true... To my understanding, the autotragic is 4 speed with a slightly longer final drive ratio. So yes the gearing has a higher top speed. But you must also take into consideration, drive loss in transmission is a factor... You loss about 10-15 whp though torque converter... So lets put numbers into play; if all things remain equal you tune an autotragic to 300hp... You need to subtract 10-15hp from these numbers... Then your left with 285whp...

5speed setups, drivetrain loss is 5-8hp. Tune this with 300hp, the loss equates to 292whp. Thats about a 7whp difference to the ground between the autotragic and 5spd... Thats BIG power difference.

And with the 5 speed transimssion, you could also gain an advantage if you were to get a lighten flywheel and a high performance clutch kit... This alone will reduce loss another 2-3whp, giving you 295whp for the 5spd... Something an autotragic can't do!!!!

Then to top that off, autotragics are heavier, and can't handle high HP loads because they will break... Yeah invest a **** load of money into bullet-proofing that transimmsion, in my opinion that's a wast of money...

So if you say "stock for stock, manuals are faster".. Power for power manuals are still faster... What ever power enhancements you could do to an autotragic, manuals can do way more!!!

The only way an auto would win is due to driver... And thats the bottom line!!!

If you have a need for speed.. You gotta shift for it!!

 

Your concepts are good but you have quite a few flaws in your work. Firstly, drivetain loss in an automatic is 15-20%, meaning at 300hp the whp would be around 240-255. Manuals lose 10-15% meaning 255-270whp. This is definitely a noticeable difference and accounts for a good bit of the time difference in auto vs. manual.

Now the weight load difference DOES exist, but can we honestly say that the affect makes the car slower? 50lbs is NOTHING if you look at the car's net weight. I'm sure some of the fastest times out there are driven by larger people.

But let me tell you something about a rebuilt auto transmission. Not only will it have less drivetain loss than the factory auto (possibly near those of the 5spd), but they would shift FASTER than the manual transmission. Contact Level 10, they will tell you that any of their rebuilt automatic transmissions make for a faster car than the vehicle's manual counterpart.

And if you think you just floor it and go in the auto to win everything, you need to drive one.

I think all the benefits of the 5spd were pointed out in this thread so I'm not going to recap them, but all of us can agree that stock there is a speed gain as well as driving experience cultivated from driving it.

Sorry if I'm just a little cranky I just get upset when every 5/6spd driver thinks they're God compared to autos. There are many modified autos out there tracking better than 5spds. But of course every 5spd driver thinks they're the one that will run 14.5. lol

WOW, lol. If you can make a manual trans that would only eat 2.66% (8/300) of a cars horsepower, you deserve the nobel prize.

 

I agree with the building up of an auto tranny. But has anyone actually driven in a built level 10 tranny? Very uncomfortable for daily driving as opposed to a slightly built 5sp...

It all comes down to preference. I feel more "with one" with the car when im shifting rather than not, but thats just me...


Eric

 

You will be crying when your auto tranny goes out after a while.
That would be my argument for the 5spd....Yes, it is faster. Yes, it is more fun to drive. And yes, if you take care of the clutch, it will far outlast an auto tranny. That is worth a lot more to me than just consistent launches. I mean, I can launch pretty consistently with my 5spd, I know how to drive it.

 

Built auto > built 5spd any day. Consistency for the auto is always there. Unless you're one hell of a 5spd driver, you're not going to beat the built auto. Daily drivability is lost though with the built auto. But the question really should be "who is the better driver."

Believe it or not, you can't just mash the gas on an auto and win. As my boss says it, you have to know your car. When you know your car, you realize how it works, and learn how to drive it. BTW this guy pulls a 12.7 in his 5.0 stang N/A.

 

Compared to driving a manual, an auto takes pretty much no driver skill. Dont try and fool yourselves auto guys. Ive driven/owned auto cars (including maximas) and its FAR easier to drive auto than a 5speed. I think you auto guys are trying to make yourselves think autos are just as hard to drive.

And obviously you cant just smash the gas, but with an auto, all you really have to do is feather the car in first (if you have enough power) and thats it. Your done. A 5speed is far harder to drive with mangaging the clutch, rpm launch, shift points.


Sorry auto guys, auto maximas are for grannies...
