I got $15,000 trade in for my 98 I30 and I paid MSRP on the new car. All in all it's like I got the new car for about $500-600 over MSRP, not bad! Plus I save a grand on tax's with my trade in.

25% loss??
Hey all, never posted here before but this thread peaked my interest. I don't know much about Nissans, but a 25% parasitic loss of power from the crank to the FW's seems way high to me. FWD cars are the most efficient at putting power to the wheels, followed by RWD then AWD. Everything I've ever read and seen indicates that FWD cars lose no more than 15% of crank power at the wheels (and that is pretty conservative). 25% sounds more like an AWD correction factor. Although the car in question is an automatic, 25% is still too high IMHO. Is there something I'm missing here? Are Nissans an exception or something? 189HP is corrected for altitude and everthing right? Sounds to me like something is not right, either with your car or the dyno run.

15% loss is about what you would have on a manual tranny. Auto tranny's are less efficient and usually have losses of around 20-25% or slightly more.

Seriously, though, if those are final numbers for a 2002 auto (ie the numbers don't increase for a broken-in motor), that's pretty sad. What, don't 2000/2001 autos make ~180 HP? Seems pretty fishy to me...that'd put the 2002's right around 240 HP at the crank, not 255 as advertised...the same figures as the Pathfinder and I'm guessing the Altima, too.
Bummer.

Re: Re: yes please go back and have them redyno in 3rd
My 5'th gen with just a crappy flowmaster muffler, a custom intake, and a y-pipe made in 3'rd gear runs of:
1. 202/187.4
2. 203.9/190.4
3. 208.0/? a/f was on the graph
thats not much done to my car. I do have my AIT sensor rewired in front of my radiator, so my PCM is thinking its always colder than it is, needed to do this since i freed up some air going in and out so this would most likely lean out the car, so if it thinks its colder it will add fuel. So, hearing those dyno plots on an auto may be about right, but on a stick those sound bad. Where's all that HP going? tourque sounds good though!
