I took my car (2K2 auto) to the track the other day and was very dissapointed with my times and noticed something had to be wrong with the car. It was running slower than before since I could not break into the 14's, and the 1/8 MPH's were at 72/73. After discussing with other members of the board I decided to get a dyno to see if indeed there was a problem. My mods are franken style intake, y-pipe, and custom 2.25 catback to the stock muffler.

Here are the two runs that are shown in the links

1- HP 187.3/Torque - 201.8
2- HP 189.3/Torque 199.2

The graphs are very choppy and the shop believed my car was running rich. I have spoken to others (You now who you are and thank you) and they believe that my variable intake is malfunctioning. Any help would be greatly appreciated. Thanks

 

Yeah, your top end is dropping off like a 4th gen. I couple of people on the org have had problem with the VIS. maybe you should contact them. You probably should have the dealer examine this system.

 

Did you get your's done at DRT Racing in Queens?
Cuz I got my dyno done there and my chart looks exactly the same as yours... I have a 5thgen too..

 

Yeah I got it done at DRT in Queens. I am afraid it might be the VIS too but I really hope not.

 

187HP WTF, Baggs with 4th gen put down 177HP. Yes there is something wrong with your ride. where did the rest of the ponies go? they may be asleep. You should be in the 14's no problem.

 

maf maf maf..haha its probably being stupid..like mine

 

Damn I just recently dynoed my 2K1 Auto with UDP, Ypipe, Intake, and got 183.7whp.

Damnnnnnnnnnnnnnnnnnnnnnnnnn

 

I think the HP looks about right - 255hp - 25% drivetrain loss = 191hp to the wheels.

As a comparison, my first Dyno , I was at 200hp+ or so at the crank (stock + Y-pipe + Pop Charger), and because I'm Auto, put 155 down to the pavement.

Yep - looks pretty normal....For an Auto.

It seems you guys are missing the point here. One look at Juice's dyno plot tells me there is something very wrong with his car. Take a look at theose lines, the are all over the place. I've seen this before and I can't really remember what the problem was. Could it possibly be his VTC going bad? Or could a nock sensor be to blame?

 

Yeah something is messed up. I doubt it's VTC's going awry, but it could be timing getting pulled if the engine is detonating, which it shouldn't be. Possible symptoms: bad coils. bad gas. MAF? other... There's definitely something up, though...

 

I think you just hit the nail on the head Steve The "coils" are likely the problem.

 

ya it sonds like the coils to me too, now try and get nissan to fix that, be like umm i had my car dynoed and it's lower then it should be. they'll be like, did you know dyno's void your warranty. bastards, i'm not gonna miss nissan service.

 

Thanks for the input guys. I actually called my dealership and told them I had the car dynoed because I thought soemthing was wrong they said make an appointment and bring down the paperwork from the dynto for them to look at. I guess I got a decent dealer

 

sup man....who in hell is your dealer?

I know it ain't those f*ck face **** s*cker mother f*cking sh*tbag
scum sucking son of a ****** On Staten Island right?

 

Actually it is, they usually are pretty cool when I have gone to them for stuff

 

holy sh*t!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

amazing....

those guys treat me like sh*t.
