Who would be faster and by how much? I just want to see just how big of a difference this mod makes...

 

I would inagine not enough to take off .7 seconds in the hands of a skilled driver. There's only one shift 0-60 for the auto, and the VB wouldn't cut .7 seconds off of a shift that takes less than that. This is of course making the assumption that the 5 speed does 0-60 in 6.7 and auto does it in 7.4. Anyone else?

 

i wanna see what he has to say...

 

Even if the auto had the VB mod it still have 10fwhp/10fwtq less than a simular 5spd. Since the 5spds 1st and 2nd gear are way shorter than the auto's 1st/2nd. The result is the auto gets walked hard. But vs a stock VB auto, the VB equipped car would pull 1/4-1/2 during each shift. Basically in the 1/4 it should be good for a carlength more or less. In order to beat a 5spd you would need a torque convertor, VB and at least a 4.0 final gear (which is the same as using 205-50-15 tires). Even then once you hit 3rd gear the 5spd will still pull on you. However the 5spd would have to catch the auto first

 

I do know that the auto will shift twice (not just once)...1-2 is one, and 2-3 is two...unless you run to 8500rpm's.

Its all speculation until a stock 5 spd is run, then, with the same driver, same conditions, evaluate the difference. Its hard to compare evenly because of the different launch technics for auto/stick, so it may never be known.

But I can tell you that you can see a significant difference in the auto before and after the VB upgrade. The most important feature is the increased protection on your factory clutches


Don

 

What i'm trying to get at don is whether its possible for an auto to be as fast as a 5 speed with the vb being the only mod stock vs. stock?

 

There's only one way to find out.

 

doesnt mean the driver knows how to drive it....
i was running the same times as a 5spd(with an intake)
@ palmdale......when i get my VB mod..i'll let you know any ET time differences sweetsound....

 

don, may i ask what you had done to the engine when you ran 14.2 n/a auto?

 

when u gonna get the vb mod buss? man i must get a job this summer...

 

very soon

i havent ran with my cai and yipe @ palmdale though. i want to run to compare to with the vb mod. i should go this friday..i also should study for finals...

decisions decisions...

 

u planning to get b-pipe & muffler as well? if u go this friday let me know your 1/4 mile time. thx

 

I used to think that the 5spds were much faster, but I've recently realized I was a bit off. Honestly, when it comes to first and second gear they're almost the same. Even with an aggressive launch the 5spd doesn't come out too far ahead of the auto maxima, but the 5spd really just walks, actually more like runs in the freeway gears. I ran with Chris off the line and he has 18's, but I had an extra passenger. We were almost dead even to 60, I pulled a bit in 2nd gear.

However, on the way home that night we got some good runs on the freeway. In 4th and 5th it was two different cars. I'm sure he can attest to this, but in 1 and 2, and kind of 3 the auto's are quite impressive.

 

Sound like Don still think 5 speeds is faster than auto.
Why not you test both?

How about this..

I have never seen a Auto Maxima with CAI, Y - Pipe and VB Mod run 14's..

hope that answers your question

however.. i have seen 5spd Maxima's with CAI and Y Pipe run 15's..

so as Don is saying.. its not every 5spd thats going to run the same times, some cars are faster, some drivers are better.. every car is different... tracks are different .. altitudes are different..

but the only real comparison i can comment on is the 97 year..

97 5spds i know off running 14's with little mods

Brian V. - Intake / Pipe
Me - Intake / Pipe
theblue - Exhaust

97 Auto's I know of running 14's with little mods

Don, are you talking about the 1/4, because at 60, an auto can still be safely in second, but if you are talking about the 1/4, then 3rd would be the right gear.

 

of course I'm talking about the quarter-mile. Is there any other reason ?

Thats the only way to verify the gains from any of these modifications. True quarter-mile timed runs


Don

 

Don, What is this VB mod? I've heard a lot of talk about it...you seem to be the person to ask...What does it entail? What does it do for the car? What is it???

Thanks!

 

in simple terms, it makes the 1-2 and 2-3 shift a hella lot faster. this results in lower times. the VB mod is a tweak done to the valve bodies of auto trannys. Don in Texas does the modifications through either core swaps or you can send yours down. visit his site at mobiletek.net for more info. (Don, hope you don't mind me answering the question for you)

 

Oh, and BrianV 2nd is the auto's killer gear.

 

Check out his website. It will give you what you want to know.

Aha! it's finally up

 

Iwas just about to ask what the VB was standing for...looks really cool, but I can't afford it yet either. Ah well. Max will be okay with a tranny cooler and a cattman POP for now! :}

 

Ok...why is everybody so hung up on straight line accelleration? While the Maxima is fairly peppy, it's no 1/4 mile champ. When I picked up mine, I was looking for several strengths. Handling being one of them. Beating someone or another car in a straight line accelleration contest is just about the least skillful race I can think of and it only tests your pure horsepower. I guess nobody here is doing SOLO or other types of competition that tests the Maxima's overall abilities.

Or maybe I'm just in the wrong forum?

For that matter, how about comparing an Auto with a 5-speed on a curvy race course or road. Guess the 5-speed wins there.
