2002 Turbo Maxima 404WHP & 393FT-LBS
FINALLY ALL MY HARD WORK PAID OFF!!!
Custom Turbo setup using Cattman Headers and Y-pipe with 3" Cattman exhaust. Precision 6266 Ceramic Dual Ball Bearing Turbo, Turbosmart Hypergate Wastegate, Turbosmart BOV. Tuned with Haltech 350z Platinum Pro with Dual Channel Wideband Controller. 8PSI 404whp & 393ft-lbs http://farm9.staticflickr.com/8155/7...79003a61_b.jpg http://farm9.staticflickr.com/8151/7...79b1d574_b.jpg RT Tuning hooked it up!! They were having a couple of problem on the dyno. Problem 1: As you all know I have been having problems with these widebands since they were installed. On top of NOT being calibrated they were installed backwards. Someone installed Bank 1 Sensor in BANK 2 and vice versa. Vince pointed out to me when you put the Haltech in O2 sensor control the 2 widebands go the opposite way...for example AFR on bank 1 starts to go to 19 then the AFR on bank 2 starts to go low like 12. When O2 correction was enabled this is what was happening. Vince, the tuner, thought this was because someone put the widebands in the wrong bank. So they swapped the widebands and that was IT!!! All this time the IDIOTS put my widebands in the wrong bank.....so what was happening was this: Bank 1 sensor would try to correct to 14.7AFR but it wasn't seeing it because it was actually correcting Bank 2 so it would continue trying to correct...and VICE VERSA. This is what caused AFRs on both banks to run away from eachother. Anyway simple fix with a swap of the widebands. The second problem was spark plugs were installed and were not gapped for turbo so they were blowing out........was making 360whp on 6.5psi with spark plug blow out!!! Anyway they were removed and gapped properly. After the problems were ironed out the car ran hard on dyno and tuning went very easy. The car runs SUPER SUPER hard!!! The thing sounds like a freakin transformer from HELL when the turbo is spooling!!! No way to explain it you just have to hear it....pulls hard ALL the way to redline. Had about 5 people from the Philly crew show up to support. We all went for a test drive and with 6 PEOPLE in the car thing pulled HARD AS HELL!!! I can actually really feather 2nd so it doesn't peel thanks to those fat 245 tires. 3rd and 4th gear are just WICKED!!Driving normally you can barely hear the exhaust note.....what a sleeper!!! Vince did say torque is probably dropping off because of the 2.5" downpipe I used. He said its fine but if I wanted torque to remain more flat then a 3" downpipe would be good! But he said the car makes GREAT power. The shop that installed the turbo installed a manual boost controller and RT Tuning used that to turn up the boost 1 PSI so I could get to my 400whp number. Glad I bought that :D I'll try to get some videos later. Its my 3rd wedding anniversary so I cant be messing around with the car all day....have to spend some time with the wifey!! So this post ws kind of written VERY fast so if it doesn't make sense thats why...... |
definitely a fun day spent at R/T. Glad you got to enjoy the car on the way home after you left lol.

congrats man!!!

Congrats! 400 WHP has got to be fun on a fwd. I'm not sure I would even do anything else to it.
|
Nice, an electric cutout may solve your problem. Did the pipe go from 3 to 2.5 then back to 3?
|
Glad to have ridden with 5 other people for its first drive!! Why? Because 6 people.
Congrats javon! |
Really nice numbers. Now start saving for some tires. I had RE-11 255/35/19 and could roast 1st, 2nd, and most of 3rd what a freekin blast. Had so many kills with that car.
Taking it to the track? Again congrats. |
"like"...lol

wicked congrats mines will be terrorizing queens,Brooklyn and long island streets late nights coming soon.:D
|
:eek: I'm jealous.
Congrats! :thumbsup::thewizard: |

Congrats!!!
Amazing what a quality turbo can do at such low boost. Let me tell you 400+ hp is a whole lot of fun in our max, even with no traction. What was your final AFR and timing? |

AFR was anywhere from 11.5-11.8. I have to connect the PC up to the Haltech to get the timing. But the tuner did say he could have leaned t up more but he went conservative...which is fine I don't care. Thing makes GOBS of power and torque. |
Damn Nice Numbers, cant wait to see some Vids, get your homie to cruise by you like the other Video......:D

Acceptable AFR, it would be great if you could share the timing map/table when you have a chance. I am curious to see what timing your tuner went with. I am guessing he kept it at max 16-17degree's.
|
killer numbers. made what i expected it would.
also interested in the timing curve. probably like 18 degrees |
That power is crazy, the curve is just nuts. That setup is barely being pushed at all, turbo isn't even breaking a sweat @8psi.
|
Sick numbers man, did you do any custom internal work to the motor? I always thought about going boost on a 3.5 but im afraid of blowing the motor

I willing to beat your not even it that turbo's range yet, 12psi would be crazy.

time to change your sig
a good tune and you would be aight...stock 350z pushing 500whp on stock motors with a good tune I don't know if I'd want to push that much on my daily driver. If it was just a weekend car I would turn the boost up. Actually it IS a VERY good tune. I have a manual boost controller in the car but Im not going to touch it.....:D

Yeah 12psi would probably would net me around 450-470ish......with 430-450ft-lbs torque..... I video a 3rd gear pull last night but dont want to get banned so Im not going to post it.....BUT I do have a link to my youtube account below (HINT HINT) :D |
just saw the 3rd gear pull on youtube.....ridiculous :eek:

Links...... Contests broski

Nice fat chevy LS curves, that's what I'm talkin about :thumbsup:
Good ish' |
i couldnt get my car to hook at all with 374whp so i cant imagine what yours must be like. i would be daily driving on a radial if i were you lol

Go out and race some vettes, cobras, :D highway fun!!! great #s... OH and if you can race a 12 psi SC 3.5 any gen max so i can show the vid to a friend lmao... he still misses his old V1 kit .put it on FB
|
well if I do it will be a 4gen on e85, stock motor, sheet metal intake, fender exit cutout and hopefully 500fwhp
again congraz enjoy the car, get a oil cooler .. and I wouldn't change anything less it's just to get a # on the dyno |
I thought this was VERY interesting..
I took my fully bolted on and tuned ALL Motor Maxima tune and laid it on top of the Turbo tune......:eek: Before (All motor): 275whp @6000rpm & 258ft-lbs @4700rpm After (Turbo): 404whp @6200rpm & 393ft-lbs @4500rpm DIFFERENCE: +129WHP & +138FT-LBS @8psi :eek: :eek: http://farm9.staticflickr.com/8433/7...416e3d4c_o.jpg As you can see there is no lag at all. At 3000rpms Im making 148whp & 260ft-lbs vs. 127whp & 224ft-lbs. At 3500rpms Im making 192whp & 288ft-lbs vs. 154whp & 231ft-lbs. Basically increases through out the ENTIRE RPM BAND!! SWEET!! |
Glad to see its all come together! It takes a while to get there but once its right its all worth it!
