ight guys, I dont have a maxima or even a nissan for that matter, but my friend has a 1990 maxima i dont know all the details and stuff but i know it is a 5 spd manual and has a comfort shift and overdrive and he thinks that he hit 104 mph in less than a 1/4 on the street. I was wondering if that is at all possible since I couldnt say not knowing much about maixma's.
thanx

mmmm it could be possible with upgrades...if his car is stock and he saying he getting that fast, and its a 90....means its a VG engine...Id say he needs to re measure how long his 1/4 is.....no doubt he would run it in 15.something seconds

There is no comfort & overdrive button for a 5-speed manual.
Please clarify.
Also, any mods?

those numbers seem way off for a 90 max

I have a 94 max. What exactly does the overdrive and trany comfort does? And how does it effects the life of the tranny? Should a person drive with these on all the time or not?

tell him he needs to calibrate his **** dyno again.

he'd have to be doing low 14's or even high 13's in the 1/4 to be hitting that kind of speed within a 1/4 mile. unless he's boosting or has a big shot of n2o that won't be possible with simple bolt ons.

COMFORT setting shifts gears at a lower RPM than normal.

POWER shifts pretty close to redline.

Overdrive locks out 4th gear. This is good if you're in stop & go driving, or not going much over 40mph for a while. Don't leave O/D off if you're gonna be driving on the highway.

You can leave comfort/power on either one all the time. Shouldn't do any harm.
I wouldn't leave O/D off for an extended period of time though.

power doesn't make it necessarily shift at redline since you can have the power switch on at lower rpm's. it just holds the gear longer, which at the end of a gear helps make it shift at redline. it will still keep it in gear longer even when not taking it to redline.

how come its bad to leave o/d off on highway?

Less wear and tear on the engine, as well as better fuel economy when using the O/D - thus allowing the car to shift into 4th gear. Using O/D will run the engine at about 2000 RPM at 65 mph, for example, compared to ??? without the O/D on. I'm not sure because I typically don't do it, but it would be much higher rpms!

Thanx for all the help guys. mayb someday i will have one too.

Yea, you're 100% right. I was saying redline w/ racing in mind. Sorry, lead foot. hehe

well in the case if it does have a comfort switch with a 5speed. someone had to do a trany swap or some dam idiot put the button in but it does nothing with a 5sp tranny

I just think this guy's not sure what he's talking about. After all, he owns a VW. LOL

in some cases its better to leave o/d fuel consumption wise. you actually want to try running these engines at around 2500-3000 rpm for the best fuel economy. if you ever take long highway trips you'll notice that you get better gas mileage when giong 75-80 or so compared to when going 65.

reason being is that between 2500-3000 rpm is where the peak torque of the engine is. the peak torque is where the engine is most efficient at burning fuel and air. this is where the peak gas mileage occurs.

i haven't found out quite yet but rpm's will probably also play a big role in fuel mileage/torque. If your peak torque is at 5,000 rpm or even redline it would have terrible gas mileage and it would be very hard on your engine. having peak torque lower is nice since you aren't making the engine work extremely hard and its getting good gas mileage as well.
