Ok I want to know Who has dynoed their Autotragic's and what Hp and TQ ratings you got, also what gear where you in when the dyno was done, IE 3rd or 4th, I want something to compare to b/c not many people have dynoed their auto's so anyone that has post your #'s and what mods you had when you had it done.

So Far I am at 150 hp and 167 ft/lbs with CAI, GReddy sp and Rt Cat, I will also have my car dynoed tommorow after about a couple weeks with the warpspeed y-pipe on also the oil was changed last week too. I will post the new #'s tommorrow.

99 sel, 157hp/176tq, last month, 3rd gear

I'll looking for a good intake and then will dyno again.

any recommendations (don't want to cut holes though)...

 

hey guys...shouldn't a STOCK auto dyno about 150whp????

 

Dynoed my auto (3rd gear) this past summer

164hp / 189.5 ft-lbs
With CAI and Ypipe.

 

I dynoed my stock auto at 155hp and 173tq last summer.

 

I Also dynoed at 155 and 173 but I had a cai.

aight i got my car dynoed again this morning and my best run out of 4 was, 167 hp and 195 ft/lbs, i gained 17 hp and 28 ft/lbs, I am very happy with the improved hp and very surprised with the TQ, but I still think somethin is wrong with my car and as soon as i get some money im gonna do a compression test, let me know if anyone has done this and how much it costs.

Have you considered Hybrid?

What should i look for when checking my Knock sensors, ie what is good/bad, let me know.

The link above does not work, try this one.

My stock 1995 GLE dyno'd out at 152 fwhp and 175 fwtq.

 

I'm not trying to flame cyrus by saying this, but as a whole you need to look at other problems with a car other than the KS. I was having a KS error and found out it was a bad fuel filter and dirty injectors.

 

Here is my dyno, with CAI and Y-pipe:

Even though I only dynoed 164hp, you have to look at the HP curve, You'll notice that with mods you have more horsepower all through out the power curve.

From looking at the two graphs (estimating):

RPMS : Stock : Mod
4000 : 123 : 130
4200 : 128 : 136
4400 : 132 : 144
4600 : 136 : 151
4800 : 141 : 157
5000 : 146 : 163
5200 : 150 : 163
5400 : 145 : 161
5600 : 142 : 159
5800 : 136 : 156
6000 : 125 : 148

If you look at the curve after peak horsepower, you'll notice that the with the mods you hold your horsepower, and don't loose power as quickly.

 

my auto dyno'd 171 hp and 183 lbs torq

cai,y-pipe,cat back

 

I feel so incomplete, I dynod the same with the a 5spd...

 

well, "I" think I have a "factory freak".... but who knows...


and remember there will always be faster/more HP cars than yours..

that's why we mod, right?? to improve and get bigger/better numbers

 

I think that is pretty low for a 5 spd with a CAI/Y-pipe/cat/catback?
I think I should be somewhere else on the chart. I was looking at yours and I was almost line for line with your car. Mine was done in 3rd and I topped out at 173@182lbs. I think I need to redo it.

 

Dang Guido, your torque curves are way different than mine. Your torque starts off good at 3400rpms (175fwtq), but then it falls into the 165fwtq range from 3800rpms until 4600rpms and then begins to drop. Your HP falls off at 5200rpms too. My torque curve stays at 170fwtq+ from 2200rpms (start of the run) until 5800rpms and then starts to fall. Peak tq (193fwtq) occurs at 4400rpms. I hope that Y-pipe made a big difference in torque for your car. YOU ALSO NEED AN INTAKE!!! You need to get that thing to breath better up top.

We'll see how she does at the dyno on Sunday.


Dave

 

Anachronism - thanks for the intake link...

dafro - did adding the y-pipe increase the cabin noise much?

thanks,
rob

 

And how did you figure that out?

 

157.8hp and 174tq. with CAI, UDP, Catback and Ypipe.
230hp and 260tq with CAI, UDP, Catback, Ypipe, test pipe and 100 shot.

 

the y-pipe alone won't add much more noise but if you add it with a Catback and rt cat it is pretty loud.
Ryan

 

Ryan,
I dynoed at 165hp and 183ft/lb. I will have to post my dyno sheet so we can see how the curves match up. You have more torque so that must explain why your max pulled ahead slightly when we raced.
Ted

 

Ya we will have to compare sometime, i tried to take a pic with my digital camera to post it but it came out really sh!tty, I need to get it scanned then i will post, I was also talking to nigel today after he put on my Agx's and he said that i might have a timing problem, and that i could be losing a little hp from that, cause according to what some poeple are puttn down stock i should be up around the 175 range, we will see i am also thinkn about changn the spark plugs to see if that makes a dif.
Ryan

 

Yeah, I'm eager to see how she'll do, it definitely pulls a heck of a lot harder than it did before. One mod, one dyno.

 

Didn't anyone else notice this? That's more torque than any bolt on 4th gen I've ever seen, auto OR 5 speed. Whats the deal...?

 

Ya When I saw my graph after the dyno was done i thought that was odd but the 2 runs in 3rd gear where really similar, the other was 165 hp and 191 ft/lbs, I will post my dyno graph very soon, there is something a little odd though, there is a spike right off the start in 3rd, so i dunno if they did it correctly, once i post the pic let me know.
Ryan

 

Mine has the same characteristic
http://www.bryanb.com/site/maxima/dyno1.jpg

I think it might be when they started the computer, if they hit the gas and the button to start the reading at the same time, then the computer can't balance itself out?

 

I don't understand how or why auto manufacturers are allowed to post horsepower and torque numbers as they do today. I'm not sure if they all do it: maybe someone on this site knows. I've read F*rd does it with their M*stang. Since 1971 or 1972 manufacturers were required to measure figures at the wheels so "gross" HP numbers from years before became "net" HP numbers and of course figures were much lower as a result. My '72 Olds 442 had a "net" rating of 270 HP: maybe i should start telling everyone that it's 340 HP, which was it's "gross" rating in '71. Now i'm finding out that my autocrapic Maxima only has 150-160 HP at the wheels? Big whoop!

 

Marketing.

 

Here is my dyno for anyone that doubted my 195 ft/lbs tq.

[img] c://dynograph.jpg [/img]

 

I dynoed at only 267.7 HP and 271 ft-lbs....next week it'll be better . Dude was that you I saw racing down Harmony? Did you hear my new horns?

By the way your pic links don't work, you can't link it to your local drive, you need a server.

Nigel

 

Ya that was me , my girlfriend and had just eatn dinner and when we came down harmony i saw you pull out of the safeway parking lot and decided to gun it to see if you would bite hehe. I couldn't hear your horns my engine was roarn pretty loud. I'll hafta really race ya sometime to see how much i loose by. Ohh ya Iv also decided to do the 5-speed swap (need to save some money though), I want to get it done sometime in the summer. Just wondern if you know anywhere I can get a 5-speed tranny with low miles.
Ryan
Ohh ya do you know where i can post pics so they will show up, or how to set up my own server.
