does anyone know whose car this is and if this person is still on the org?

if you do know who that car belongs to , is it a cali emissions or a federal emissions car>?

 

mine is 99 SEL i know mine is fed cause i checked by the VIN and i dont have the link that show you if its cali or fed

 

Is my car Cali or Fed spec?
Raise your hood. Look for a shiny metal identification tag fastened to the passenger side of firewall. The top row is the Vehicle Identification Number, starting with J. The second row is model information. The first five characters are BLHUL. The 12th character is the destination:

N = Canada
V = California
U = US, not California

That's my buddy Szymon from Chicago, its a fed spec and his name on the .org is max7, he doesn't post much. I drove his car at the 1/4 once.

 

my vin indicates v for cali but i thin its fed specs, when i ordered my y pipe and cat they from WS they told me a o2 sensor behind the cat is fed specs , also isnt the y pipe bent different for a cali spec car? im 96 btw

 

His Car is my fav max of all time and how come it's so fast, i think its the fast 99 i have read about on the org. he is running 14.6 with 2.3 60ft @ 96mph. i bet if he got like a 2.2 or 2.1 60ft. fround what i seen and what i know now i am sure he could run 14.2-14.4 as it is now.

anyway the reason i ask is i notice he has an underdrive pulley and i wanted to ask him if he thought it made a diffrence? he has the same mods as myself but he also has a UR underdrive pulley so i am guessing that may account for the little extra "go" needed to achieve those times that he has. if you know nealoc let me know

other than my car being Cali emissions and not having the underdrive pulley, i think this is a good benchmark for me to work to since everything else is kinda the same.

 

His car is actually faster than that he ran a 14.1 or 14.2 on my slicks late last year, only ran on them twice though so he never really got a good launch I think his best 60' was a 2.1 or 2.0. On that day he ran the 14.6 back in 2001 I drove his car and ran a 14.5 on like a 2.25 60' but he didn't want to post up that time or timeslip because he didn't run it himself.

Look at his dyno compared to yours, he's putting down like 15hp and 15tq more than you are and I expect that that is the explanation why his car is significantly faster than yours. Also realize he was running at byron which is a fast track and on the days we were there it was like 40 degrees out.

The main question is why is your car down on power. I don't know enough about cali emissions cars but it has always seemed to me that they put out a bit less power than fed emissions cars. Cali emissions cars still keep one of the precats don't they?

 

well the only other thing i can suspect is that my car may have been broken in incorrectly by the original owner why else would i be suffering now. I believe also it is because my car is a california emissions car as well, and that extra precat on the front engine mainfold was not removed with the y pipe install. this has to be holding some power back. My car does run extremly well, i have done a tune up , knock sensor, plugs, and fluids.i also believe that maybe my 02 sensors are getting tired and old. i did replace one a while back at a cost of $120 so i am not just going to replace the other 3 unless they throw some codes. The only other thing i can assume from the information that i have is that the under drive pulley does add some gains, look how fast his car is for the mods he has. i wish someone would dyno before and after on the under drive pulley install to be sure. i am going to get an UR under drive pulley next and dyno to settle this once and for all, i hope this will help close the gap on the hp diffrence.
Currently i am at 176whp and 190wtq. his car does have 12 more whp but only 3 more wtq.

ultimatly my goal is low 14's but i am fearful once/if i get there i will wanna go faster. for now though i feel proud of my 14.7 . let me know what you think. does he still own his max.

 

Yes he still owns his max last I talked to him which was this spring but he doesn't really mod it or race it any more, he's got a boat that he spends all of his time and money on.

The precat is your main problem. The ypipe gets most of its gains from removing the precats, but since a cali spec ypipe only removes 1 precat you are reducing your gains right there. Also contrary to what some people on this board say, the UDP does free up some horsepower. It's simple physics.

Also don't judge power by your times but rather by your trap speeds, trap speeds are indicative of the power you are making. Remember what I said about the track and the conditions. You trap 93+ he traps 96+. Then remember that he is running at a fast track (1mph) and running in exceptional weather (1mph) and is making 10hp more than you (2mph). That would account for the difference in your trap speeds right there. The simple fact is that as a cali spec car, unless you figure out how to get rid of that precat you are never going to make the same power as him with the same mods. I don't see anything abnormal about your trap speeds given the above criteria as compared with his trap speeds. He just ran at a faster track, on a faster day, in a car making a significantly more power than you (extra mod and the fact that he doesn't have a precat).

Things like o2 sensors and the like do not affect your wide open throttle power so don't worry about those as far as your hp numbers are concerned.

 

Sweet thanks for the information Nealoc, well for now i am just going to get the UR underdrive pulley. I am very hopeful that Technosquare will be able to alter the 99 ECU's(fuel,timing,rev limit) and we may know today. so maybe i will be able to get MEVI and ECU. if everything looks good from there Maybe i will get the Cattman Header because this will get rid of that pre cat fo sure. so that is the plan. i was able to find the dyno of a stock 99 max 5speed as well and it belive it is Cali emissions. this is VQuick's dyno. i don't have a baseline for my car so i am not sure but if this is what 99 cali 5speed are putting down stock them my #'s are bad considering my mods.

 

dont tell me that thing is auto

 

no that is a stock 5speed dyno , i am guessing its a cali emissions car

 

here is another 99 5speed with cali emissions http://forums.maxima.org/showthread....=1#post3328177
