Im not sure what ima do at this point. Might tune with utec just to go back to dyno and see how it runs. Even though that wont help with EVT not being hooked up. Edit, your wanting to go 350z haltech right?

yeh, I decided to go 350z Haltech. Sold the UTEC to a worthy owner already!

Oh cool, I can do pnp 350z haltech no prob!

I bought a custom length intake from knights, then had a local iron shop fab up the maf block for me. Total cost 60 bucks out the door from them. If you buy it from him and have it sent here I can knock that out for you as well and even powdercoat it gloss blacc for u.
Only have gloss black and clear. Waiting on candy and Chrome powders now.

Went back to the dyno to see how its running! More normal graph now!!


280hp / 253 tq (uncorrected was 283/255)


notes: changed rev limiter to 7200, didnt make utec correction after 6900 rpm, afr was 14's+ up around there. The run was with cutout taken off! LOUD!


Best thing from going back is seeing the 5k to 6k gains! was making 180hp at 5.2k now making 245 ish. car runs so much better then it did before.


This only on utec tune, timing not messed with much, mostly fuel. NO EVT hooked up still!






Comparing my best run on the first dyno trip to todays!

my God, those numbers are better than ****!

Wow nice! So are the only differences between the two dynos an intake, bbmaf, 3" y pipe, and tune?

WOW!!! So much power left in that thing!!!! You should hit 300 no prob!!! Nice seeing the progress man!!!

thanks! it was around 271 with cutout closed! it was open for 280 haha so i had to post the BEST numbers !!! haahahh


ya ive added since last time, 3.5 intake and maf, utec tuning, and had cutout open. which the grap is just as decent with it closed!

Main thing is the 5k rpm range looks a lotttt better

goal is get close to 300 on stock cams as possible!!!


I really like how the power is not falling off too badly after 6k!!! on the street it really pulls till redline, well if im not spinning! the cold road around here have me spinning quite a bit in 2ed now.


im still not shifting hard at all! Still a good way to go with the car but its getting there!

What are you planning on doing with the two vias?

If you get a UD pulley that would help free up some power, can't remember if you got intake spacers or not and perhaps deleting the VIASs and getting BOPS for both? I thought you were going with the Haltech ECU?

He's getting as far as he can with the utec as he has it in hand already. Good numbers darren

The 02 ecu is currently controlling them, i might do something with intake manifold stuff later on

I wont be getting a ud pulley, if anything a ATI damper, which is not needed really, so ill leave it stock. Its running stock intake manifold setup.

I might eventually run a haltech but utec was easy and cheap. Ive got all this osiris ecu swap stuff too, thats what ima try and run next.



Thanks!!

Sick numbers.

Grats.

thanks!


Remember that was with the cutout open! No restrictions at all! AND HOLEY SH** was it LOUDDDDDDDDDDDD

Also thats with the new 3" collector ypipe!

Dude I didn't see this! Awesome... You should have let me know you were hitting the dyno so I could video tape. I told you it felt like 280whp....

Ya, thats with cutout open. Ima hopefully go back in the next few weeks with osiris this time!!!!!! Hopefully!


Txt me bout them 18s.

NIceee!!

Thanks!



Crazy i know! But im really trying to get in the 290s with stock cams!

holy bumboshyt!!!! now this was more like i was talking about...... yooooooooooo this has the posibility to make some good maxima NA history... get sparks IM

Yeah! The new graph shows how crappy it was running before! Im hoping it will make NA history! Far as dyno and track! Im a noob at the track so i dout times will be worth a crap for a while! hahaah I actually might get a Custom I/m but that would be WAYY down the road.

nice numbers...

didnt jay_pee99 make 280 and 267 tq before the cams..and didnt sparks03max dyno 280 as well?...both 02 vq35de motors.....maybe im missing something

Im just in the early stages of this! The tuning is street done, and the motor still isent 100% right. no EVT hooked up either (which could be hurting overall power some, or not)

I have not seen a dyno run of a EVT equipped motor, working then with it unplugged. So im really dealing with a LOT of unknowns with this motor. It will take more time to get it figured out. But when its figured out, this motor is a improved DE version, so there should definitely be gains over the older DE's


Overall dyno dont mean a whole lot anyway when comparing to others. What im interested in is comparing my car to itsself. The first time i went compared to this time is TOTALLY different!

Oh also, look at how the power is so flat from 5800 to 6800 it does fall after that but i think its due to the utec tune in that area (i changed redline and didnt change fuel in utec map)

I c

change it change it change it!!!

^ haha hoping to get this Z ecu with osiris in actually! Got the car on jack stands for a lil bit tho. Tidying some stuff up. Moving my battery ground (its in trunk now) checking things over, adjusting the coilovers up, for my wheel change. Going with G35 18's painted gunmetal with 245 45 18 KDW's Looking to get Z Forged Tracks tho hopefully!

This is the dyno shops youtube





Was not a open cutout run but just a quick vid of the car on the dyno

hah dang, looking at the engine when i let hit the redline and let off the gas, it really dont move at all! wow

it climbed RPMs so much faster this time.

climbed like a regular 5.5 does to me

Compared to my first dyno trip, its totally different!


Once i get EVT hooked up and more tuning, we will see what its really doing!


Even now 5700 to redline is a lot better then 02 with a regular i/m, shows the stock 09 flows good uptop

tq gain @ 5200 rpms = omg. Nice progress

Hey I forgot about that text, I'll get back to you.

Ghustle I don't know what you consider a regular 5.5... If you're using JP and my custom IM dyno runs for "regular", that's kinda silly.

A regular VQ35DE with the same boltons (and even same UTEC) that he has looks more like this.

^ ya that's a better comparison, stock manifold and basically same mods

Sure he made more power, I'm just saying the way it climbed was the sam as a "regular" 5.5.... not hating on the swap cause I do love it, I just don't see how it climbed oh so much faster, but eh
