    Real World Test 3.2 VS. 3.6

    I have a 2004 3.6 CTS, and my dad has a 2003 3.2 CTS. Today, I was following him on the freeway. I thought it would be fun to see the difference in power. I pulled up next to him at about 65mph and smiled. I motioned to go on three. We both punched off. I jumped a car length right off the bat. By 100 mph, he was several cars back. When that variable valve timing kicked in at higher rpms, it really pulled. His 3.2 seemed to run out of steam. It pulled so hard on him that it seems like the 255 hp might be a little underated. It seemed like a lot more than just a 35hp difference.

    that's what i thought when i pulled on a 04 maxima (more hp and torque) w/2 passengers in my car. Unless my volant intake is giving that much more power which i highly doubt, our cars might be underrated.

    I would have a fair amount of faith in the 255hp estimate; The SRX is rated at 260hp, and thats probley due to exhaust. 15hp, which is not a lot, is still wishful thinking if you're expecting 270hp out of an engine rated at 255hp. This isnt to say that the engine isnt capable of of 295+hp with mods. From my experience and education, I can tell you all there are a lot of variables in what your final output at the rear wheels is:

    Air temp and moisture, a/c on or off, power curve and shift points affected by transmissions hydraulic pressure, computer determined shift points, octane, weight of passengers and various options (heavy sunroof), wheel/tire/rotor size all affect unsprung weight, and numerous other variables.

    A lot of people who have added or modified their air intakes think that they have drastically increased HP. While it may seem or feel like 7-12hp, its realistically 2-5hp. What you've done by increasing airflow is actually adjusted your power curve. You effectivly utilize more available power at lower RPMs than previously.

    I can see how you toasted a 3.2CTS with a 3.6CTS, but the Maxima experience has me baffled. I would attribute it to poor driving, and a/c running for the Maxima; good shifting by the computer, and a little luck for the CTS. I will not discount however, that the CTS may be a faster car than the Maxima, but I'd like to see a few more shootouts before I decide on that one.

    Both our cars were in sport mode with A/C off. The A/C shuts off at full throttle on most cars anyway. Including the Maxima.

    as i said in other thread, i was expecting to lose and i won not once but twice. Which was pretty weird. I know for a fact that intakes don't help at all but i just couldn't belive that a my car beat the maxima.

    Didn't someone dyno their 3.6L and get 22hp @ the rear wheels? That's about 27xhp @ crank.

    Dont be surprised if it's underrated.. Ford advertises the SVT Cobra @ 390hp, throw it on a dyno, it made 381@ the rear wheels, which equates to 448hp.

    I was the one. It put down either 221 or 228 at the wheel. However this place sucked (took 1.5 hrs to set the dyno up with my car. Technician put 100,000 rpm as maximum value and thought machine wasn't getting my revs properly) and i didn't really trust their figures.

    I think the valuable lessons that we've all learned here today are:

    3.6l CTS is faster than 3.2l CTS,
    Maximas suck,
    We will never truly know the ponies that reside under the hood,
    and racing other cars in your CTS is very very fun.

    Drive it like you stole it and dont let anyone tell you otherwise!

    Not true...all we need are a few more dynos. the more the better

    Re: Real World Test 3.2 VS. 3.6

    Closest thing I could find to an apples to apples comparison comes from R&T mag. Current road test review lists the CTS 3.6 at 6.6 0-60, 15.0 @91.9 in 1/4 mile, and 18.9 0-100. The Maxima 3.5 SE is 6.5 0-60, 15.0 @95.4 in the 1/4 mile, and 16.5 0-100. The variables encountered when playing around on the street are vast, which probably accounts for the favorable showing against a Maxima which is clearly making more power. This can be discerned from the trap speed of 95.4 against the CTS at 91.9. Also, note the fairly large 0-100 difference. I may also have been incorrect in my assessment of my current CTS's performance against the BMW 330xi I got rid of. I had been using the figures of the manual cars instead of auto to auto comparisons. It appears that the CTS is at least as quick as an auto trans equipped 3 series Bimmer. As my CTS continues to break in (less than 7k) it continues to amaze me with its performance. It's getting noticeably quicker. Not a bad thing!

    Re: Real World Test 3.2 VS. 3.6

    Im beginning to think people lack balls and dont know how to drive. I take pride in the fact that I'm rather fearless and wreckless on the road. Chastise me later. I drive with full confidence and no inhibition. The only thing I can fathom at this point, is that any car we've beaten, that is known to be quicker, has been driven by an absolute pansy. Sorry guys, but tests are tests, and numbers are numbers. If we're beating '04 Maximas and BMW 330s that every car mag out there insists is quicker, im gonna have to say that these guys are holding back and too afraid to exceed the speed limit. Like i've stated previously, theres a million variables involved in power output, we could or could not be faster... bottom line, I think we end up racing ourselves. Would you race a Civic or an Escort? Nerp; If I was driving a car that I knew was statistcally faster than a CTS, I might not bother to prove any points. This may be what we've come up against. Se La Vie. Drive hard anyways, and continue to prove em wrong....

    Re: Real World Test 3.2 VS. 3.6

    You guys talking about mixing it up with the Maxima 3.5 SE brings me to offer these thoughts. I love my CTS for a variety of reasons, but . . . I'd never put it up against my wife's '02 Altima 3.5 SE (unless she was driving it) cuz it would eat the Cad for lunch.
    Here are some car mag test numbers on it: Zero to 60 mph 6.3 sec - Zero to 100 mph 16.1 sec - Zero to 130 mph 27.0 sec - Street start, 5-60 mph 6.7 sec Standing 1/4-mile 14.8 sec @ 96 mph. From my personal experience of driving her Altima pretty hard (when my wife wasn't in it) those numbers seem pretty accurate. I'm not sure of the weight differential, but the Altima is fairly light.Even has an aluminum hood and rear deck lid. But the torque steer is brutal until the front wheels hook up. The VQ engine is sweet, but the rest of the car is very uninspiring (read that as cheap). Those are my experiences, for what they are worth, in case you line up next to one on your local boulevard.
