the '98 or '97 Q45? I had a small run-in with one late last night on the beltway. They are rated at 266 hp or so and 278 ft-lbs toruqe. Aren't they highway monsters?

BTW, if this is OT, sorry.... it can be moved.

 

97-98 Q45: 266HP and 3890lb

Despite all the weight and relatively not all that much horsepower they still manage to be pretty quick because of hella good gearing for both 0-60 and 1/4 mile runs.

They definitely qualify as highway monsters. Their 3rd (1.00:1 exactly) gear takes them north of 135 mph before they hit their crappy OD and go nowhere.

 

How'd you compare this to the 2k2? Given, it seems the 2k2 dyno's show on average 265-270 lb.ft of torque at the crank (based on a 15% tranny loss).

 

A 2k2 Max (stick or auto) would smoke the old Q. 3200-3300lb vs. 3900lb and they both have about the same power.

Dynos tend to show a greater amount of torque than horsepower probably because there's greater loss at the high end where peak horsepower is measured. Since peak torque occurs earlier where there is less loss, you probably wouldn't use a 15% figure for torque. Maybe more like 10%.

There are higher losses in the drivetrain at high RPM than at low RPM. So horsepower numbers would be most effected on the dyno (hence they always seem low compared to torque) and torque numbers would seem high (hence they always seem high compared to horsepower). So I doubt that the VQ35 in the Maxima is making 265-270lb of torque. It's probably right around 246 lb-ft as specified.

Does that make sense?

 

Lots of it. I never thought of it that way

Thanks for the explanation Steve.

 

They are high-mid 15's cars. I drove a new 02' Q45 for a weekend and it felt faster than my Maxima. The car pulled like crazy above 3500 rpms. The only thing I didnt like about it was it didnt shift at redline and the Steptronic(dont remember the Infiniti name) is useless.

 

Nauman was referring to the older Q - not the brand new one

 

yeah, it was definitely the older Q, a '97 or '98... it had no HIDs either. I was minding my own business cruising around 75 when I see this guy coming up fast and tailing me. I had just moved into the third lane to get past a slower car. He follows close and I gun it.... I get some separation between him and then he shifts over in the lane next to me and hits the gas the same time I do. He had his front bumper at my front door when I started pulling slightly. He ended up at my rear bumper when we hit traffic and had to slow down. It was close, but I thought he would kill me bad given the reputation of the Q being a highway killer.

 

modz own3d him

 

I heard the first generation Qs were faster than the second. (The third, 02, is SICK)

 

PW

heheheh

 

\

I was referring to the last gen Q running mid 15's. The 02' Q runs somewhere around 14.7 i believe.

 

Get a SC and walk him. Hehehe

 

Oh. It sounded like you were talking about the new 02. My bad

 

pssshh...PSSSsshhhh

Nauman - nice kill by the way

 

Exactly.

Go Nauman! Hehe

 

My friend has a 92 Q45 and we race a lot. so far I havent been able to beat him. When we are both in first gear we are nose to nose, then once I shift into 2nd he walks on me. the earlier Q45's have 278hp I believe and are very fast. But he says that his car is faster than the 97-99 Q45's. Does is seem right that he is faster than me? his car is much heavier.

 

This may very well be true but check out this chart : http://www.frankencar.com/product_i/...hart_large.jpg . At 5500 RPM HP and TQ are about the same, the HP is at about 205 FWHP at that point and then goes up a little bit more. I still think nissan is underating the TQ.

 

It's a mathematical certainty that HP and TQ will be equal at 5252 RPM, about where it is on that graph.

Horsepower = [(Torque x RPM) / 5252]

 

thanks guys... I didn't think it was much of a run since we had to slow down so only after a little bit... it was fun though The older Q's with the 4.5L engine were faster than the ones that came after.

Pshhh Pshhh? Give me some time

 

 

they'll give u a run for your money
