what's everyone, just took my car to get tune uprev but I wasn't really expecting 330whp on a dyno jet..!!
2005 350z 6mt:
vortech v2 kit-3.12 pulley
550cc DW injectors
stillen dual exhaust 2.5
edge racing resonated test pipes
kinetix v+ intake pletnum.

weather was a about 60% humidity and 101 degrees. it was tune using 91octane
my tuner said he made everything he could to get the most out of it on a safe side. Now ive had heard a couple of guys making 10psi with the 3.12 pulley and mine was making 7psi I'm gonna double check everything in case I have a boost leak but I don't think I do. I just don't know if it's my car or the tuner since it was his first time working on a 350z. any suggestions are welcome.

 

Who's your tuner? What's you're Pulley combination?

And OP, you may want to have the mods move this to the FI forum for better help...

 

330 whp isnt that bad man to be honest. Especially if its an AT car.
I mean, a stock z or lightly modded is like 220-260 at the wheels lol.

You dont have very big injectors, so i im agine you dont ahve much in the way of a fuel pump either. Just throwing out ideas of where to start looking is all.

Those will limit your tuners ability to make power.
Pulley as well, but i dont know much about what pulley you have listed.


Im huge single turboed, but i believe we went 850 injectors and a 400 fuel pump and still it will be THE factor that limits me for now.. should be around 5-600 whp. MAYBE.. but w larger fuel flow capacity, they can dial up boost ( or in your case perhaps up the pulley as well) and make more and more power.

Id look there first.. im sure other more experienced folks will chime in if you have a mod move this to the FI section.

 

With your small exhaust small injectors and I'm assuming 3.3 or 3.12 pulley in 101 degree weather 330 is right about where you should be. When it cools down you will probably pick up 50 whp or more

 

Your numbers look to be about right. Just need to get a better tune. My 2004 350Z with similar mods made the following numbers below.

First Tune stock Vortech Pulley:
320.56 whp
271.21 torque
5.38 psi

Second Tune with 3.12 Pulley:
378.76 whp
316.21 torque
8.76 psi

 

was a shop called tuning technologies in Colton Ca . umm I don't really know how to move the forum since I'm kind of new in here.

 

it's a 6manual tran. and yeah I know it's not that bad 330 but I've seen guys doing close to 400 with the same mods.

 

well the injectors and the fuel pump should be able to handle close to 450whp sine there's members from here that have the same mods. and yeah I have the 3.12 pulley.

 

woow man.. thanks for the info now I don't feel that upset. seon d tune 8.76!!?!! what pulley do you have??

 

Not in 101 degree weather with 60% humidity. Those numbers are mild 60-70 degree weather I'm sure.

 

I had the 3.12 pulley and here is a list of my engine and exhaust mods.

Engine:
-Vortech V-2 SQ SC-Trim Supercharger with 3.12" pulley
-5/16 Motordyne Plenum Spacer
-ARC Cooling Panel
-Sun Hyper Force Ignition System
-Crawford Headers
-Stock Injectors
-Custom oil cooler from Zcargarage

Exhaust:
-Amuse R1 Titan Exhaust

 

u making right #'s for 7psi, u definetly have a boost leak if not geting a full 9

 

true.. well I'm prob gonna go e85 with with 850cc and upgrade pulley for more boost.

 

yeah I think I do.. I'm gonna make a leak inspection hope that was is the problem..

 

Your running on stock injectors? Do you have Orsiris?
That pretty good with 375whp

 

Yes, Rob at ZcarGARAGE tuned my car with Osiris.

 

i just got my car back from Rob at ZCG. i have a 3.12 pulley with 660ccDW injectors, 255walbro pump, MD 5/16" spacers and Up-rev GT maf. he tuned with Osiris for me and my car made 390Whp and 336Wtq. im still running stock exhaust, stock cats and stock front bumper so you should be doing better numbers than what you ran. i highly recommend goign to see him.
heres my dyno sheet. and this was @8psi on a 91 conservative tune.

 

nice results, yeah that's the same thing I say I should be making easy 400whp. where is that located?

 

no I have 550cc DW injectors and yes he used uprev -Osiris

 

Seems like a boost leak.. the tuner would have had to pull a metric crap ton of timing to get results that much lower than usual.
