I haven't got a chance to dyno my max yet and i was wondering what horsepower at the wheels my car puts out. This is my setup: cai, y-pipe, rt cat, greddy cat back.
I am asking this because i have seen different charts on people's hp and they all varied. Thanks for any numbers you can figure.

 

185-195 WHP

 

If a stock 97 SE 5-speed does about 160 at the wheels, a GLE would be automatically a few HP below that because of the auto. So we're at 150 stock. All together, I think the bolt-ons would add 20-35hp, for 170-185 at the wheels.

I'm just going off the top of my head on this, so anyone feel free to correct me.

 

I was wondering because i saw someone without cai, just pop intake, and without the rt cat have something like 180fwhp. So i was wondering what the difference in the cat and cai would make my hp. Anyone have this setup and has tested it?

 

DynoJets read differently. You can only go by your numbers on the dyno you test on. You can't compare your numbers to some other guy three states away on a different dyno. When you add mods, you need to test your car on the same dyno. Dynojets can vary 5% between units or 10-15hp and torque.

Simply put, don't compare numbers or you'll be disappointed.

I dont know about 150 to the wheels. My 97auto had 165hp and 180tq to the wheels stock(with the filter out)

I think 95-96 have a little bit more power from the factory. I know it says 190 but the 97-99 is like 185 or somthing. Dont know why I think that I saw it somwhere.

 

WoW 98MAX, that is a very respectable auto q/mile time!! Gotta respect that!!!!!!

 

With my setup I can get under 15 sec on 1/4mile right?

 

There is a calculation problem that gives you a rough estimate of how much HP and TQ you are putting down. Anyone know of any sites? I found one be accident about a week ago and i tired it. It asked for my weight of car and 1/4 time and trap speed. It said i had about 171hp... forgot the torque, didnt look. So i figure im pushing aroung 169-172 or so give or take a few HP's. This on my 99 Cali auto Maxima and just a CAI.

 

There are a few sites that have that hp calc and q/mile estimation one is importspeed online and another is from one of our very own members, I don't quite remember his name but he has a s/c Max and is from Chicago and runs a 13.5 auto!! I think and another is from Justin Gadaladge w/ a link to Altanta chassis Dyno or something like that, it is on his home page, check it out.

 

I had mines on a dyno a few days ago.. I have a 97SE she was throwing down 159hp w/ 169pt @ 133mph... Second run she made it up to 163hp w/170pt @ 137mph
Which I don't think is to bad for a Stock Max..

 

I dynoed at the Dallas Max meet a few weeks ago and I ended up with 164hp and 183 ft/lb torque. It seemed a little low, but a stock Max dynoed and he ended up with 150hp so I figure a 14hp gain from intake/exhaust isn't bad at the wheels. Everyone likes to see high numbers, but don't you lose something in the neighborhood of 15% to the wheels?
Here's my dyno chart if you care to see.

Hey do you notice that your car is slower with your 18in rims or is it not noticible.

 

I don't think that my 18"s make that much of a difference in speed. If it does I'm sure that it's negligible. On a dyno wheels don't make a difference at all because you're measuring power not acceleration If you want 18"s get em because I'm sure they weigh less overall than your stereo setup. My 18"s are supposed to weigh in at about 19lb. or so which is pretty light for 18" wheels.

Probably not... you will be doig good if yuo can hit low 15's.

You do drop in HP from bigger rims/ heavier rims. SCC did an article about it w/ a Honda Civic w/ a couple of diff size rims. They lost power the bigger they went. 19lbs is very light for a 18". I sure hope that isnt with the tire b/c i would find that hard to believe. My 16" chroms w/ tires weighed in at 37lbs each.

 

Actually, heavy wheels will make a difference on the dynojet. A dynojet measures the power by way of how quickly your car accelerates the drums. Your wheels will effect your power even if they aren't that much heavier than the stockers because of the loss to inertial mass (ie more weight is on the outside of the wheel).
