ok i ran my car on the dyno at maxus. i put down 192 whp. i'm a 2000 5 speed with a GAB intake, wsp ypipe, 2.5"catback, and an UDP. i just read that the stock numbers for my car were 190ish to the wheels. i pulled a code for a rear 02 sensor and a knock sensor. my guess that it's the knock sensors that's really hurting my power, but i wanted some other input on this.
also on the first runs we found out that my VIAS wasn't working(it wasn't the cup, it my dumbass wiring in my VAFC wrong and splicing into the VIAS wire.) the first runs i put down 178whp and 195 ftlbs. then we took the rod out and my car put down the 192 and 178. i got home and fixed the problem now. so i have the best of both worlds. but still i know my car is down on power. i'm ordering a timing chain tensioner as mine needs to be replaced, and also i'm getting the o2 simulators for both of the rear o2's and i guess a knock sensor. i'm just really hoping that's the problem and not anything else that would be major. if anyone has any suggestions let me know. thanks

 

Seems like a typical problem with A32's. Not as much A33's (knock sensor), but they are getting 'older'.

192 is nothing to scoff at, I have dynos of DEK's with ECU's putting elss than that.

Do you have the runfiles? (Or am i being a lazy and not finding them in the Maxus thread:


o2's shouldn't have much of an affect @ WOT ( aon a dyno)

 

agreed...at WOT, the o2 sensors are ignored...you can have them unplugged and they will still work the same at WOT

 

well SR20DEN has my run files and i've tried to contact him and get them from him. but i just thought that mine were kind of low considering my mods and the fact that stock ones put 190 to the ground. or atleast that's what the FAQ's said here http://forums.maxima.org/showthread....442#post275442. also the runs were made in a room will heat in the upper 90's and in texas humidity, but other guys were making really good numbers. two guys made more power there, so it's not the dyno reading low. thanks for your help.

 

Is that # (192) corrected, if so what was the CF?

The 'other' guys put more, what were their mods compared to yours? I'm hoping they were also DEK's...

Short trip to the dyno slip forum and saw average anywhere between 180 and 184. So your #'s maybe a tad low with re: to your mods. Essentially all you have is a y-pipe since the GAB is better than stock, but not as good as a real intake (JWT, custom, Berk) at least for the 3.5 this would hold true.

 

that number is corrected, i have no clue what the hell CF means. sorry what i meant by they put down more was that they set new records for themselves. like brad92se put down 315 which is his personal best, and SR20DEN put out 265. i know that brad turned up is boost a couple psi from his last dyno, but i don't think that SR changed anything, i could be mistaken though. hope that helps some.

i was the only dek car to dyno, everyone was either a 3.5 or a boosted 3.0. so another words i had the lowest dyno numbers for the day. yeah go me

 

CF = Correction factor. In this case it could be either SAE, STD, JIS, .. Or a numerical value. (1.01, .98, .99 )

Without any sufficient data (i.e ob2 scan dat logs such as timing etc) you can't really make any assupmtions.

Try specing(resistance) the KS (Knock Sensor) Though it still may pass, it might be on its way out as many sensors can 'test' out, but still turn out bad.

What grade of fuel did you use?

 

LOL

so how much money did you spend to gain 2whp?

sorry.. just had to do it!!!!!!!!!!

 

Until anyone can show me a stock A33 5MT putting 190 fwhp SAE on a DJ248....

 

it was sae for the CF thanks for all the help. one question, could the fact that my timing chain is a little loose set off the knock sensor since the timing chain is making noise? just curious
