Rate my tune please
 

i want to know if my car is normal
370z Sport touring 2010 with 40k miles

290WHP 7AT with DynaPack with 91 Octane Gas

CBE Top speed Pro-1
Y-Pipe Megan Racing ( yeah i know.. )
Test Pipes Megan Racing ( yeah i know.. )
Cold Air intake AFE power Takeda Attack
Uprev Tune

is it low ? seems low to me ... 340whp seems impossible to get for me

futur upgrade i see to get more
Upper and lower manifold from z1
headers

Thanks !

Look at my signature for what components I have with the EcuTek tune that I just got last week.

so ? what do i need to understand

your gas?
wich dyno ?

Temperature can affect a dyno by as much as 15 hp. Also EcuTek > Uprev.

FWIW, I'm a bit skeptical of the design of the Takeda cold air intakes.

Just my two cents.

me too but it seems similar exeprt the filters

Yea ive had a difference of around 15whp and the only thing that changed was the temperature outside when it was dyno'd

I just had mine done with Ecutek.
I've got 115,000 miles.

K&N Typhoon intake, Z1 intake plenum, Borla CBE, Motordyne headers and HFCs and lightweight flywheel.

6 spd manual on a Dynojet.

320 hp, 259 ish ft/lb

Tire pressure, tire position on the roller, there are so many variables.The end number really doesn't matter much, you need to compare before and after numbers from the same dyno, preferably from the same day. There's always going to be someone with a high dyno sheet, doesn't necessarily mean their car is making more power it could just be that machine reads a little higher.

I'm using ECUTek, Berk HFC, FI CBE, Stillen G3 Intake:

Base run was: 303 HP @ 7400 / 244 TQ @ 5200
Final run was: 316 HP @ 7400 / 251 TQ @ 5100

My AFR wasn't too far off, so I was surprised by how much I gained actually.

This is a good read about Dyno variables if you have a moment, its not real long, and it gives actual examples.

ok thx for the numbers i understand now
i went to 1/4miles today

13.77 @ 105mph
i was unable to get a nice launch with those tire and auto tranny
i was drifting on first and second gear

285/35/20 ( GTR WHEELS )

some people post 12.9 @ 104 mpg so my reaction time + my start pas prob bad

Reaction time doesn't affect your ET

Think I found your problem, drifting and drag racing are two different kind of racing :D

I think its my gtr rims .. too heavy and big

Its not the rims. Its throttle control. I'm guessing you're to heavy on the gas. Everyone does it the first time they are at the strip or track. It fairly amazing how much faster you can go with the same car when you can smooth out your inputs. Getting to be a pro at that will drop more time that different rims ever could. That just my two cents. YMMV

You are running 91 octane... That might account for some of the issue. Others are getting more aggressive with their tunes with better gas.

My tune resulted in this
before after
Hp 293 338
Torque 245 266


stillen Gen3 intake
Z1 headers
resonated test pipes
FI Exhaust with 18 inch resonated muffers

cars has 50K on it....

gbrettin
yea.. our super here is 91 not 93 , i dont know if it makes a good difference

chuckles
youre probably right , i did drag like 5 years ago with AWD sti so its different.. yes i was giving to much gas , loosing a sec there probably ,

i was racing vs a stock G35X sedan ( 2008 ) . i want getting him back when i was doing wrong start so i have more powa but bad starts

you see? im pretty far from 338 lool and we have same component exept headers ( different brand )

im really wondering what could be wrong ... maybe takeda attack sucks very badly

i think since ive installed my CAI afe , my tranny is answering weirdly on D mode ( auto )
i have no prob with manual mode like paddle shift , but in D mode , tranny is shifting bad when driving slowly, could be a suction problem or somethin?

Stick will get 5% more whp than A/T (+ or - very little) & the 91 octane fuel won't let the tuner pull as much timing as 93.

keep your fluid clean & that will help.

There are so many factors that can have an impact on those numbers it's not really practical to just show final whp numbers. It's just as important to list initial whp numbers as final numbers even better percent increase/change. If your initial whp # was 270 then 290 isn't bad +5.4%. Where if your initial was 285, then 290 is crap +1.7%.

Alot of variables like everyone said can have an effect. One problem though is also the gas. Ive spoken to Seb during my tune and unfortunately 91 wont get us far unlike others who puts down decent #s on 93. I dont think ive seen alot of 300s on 91, alot of them being in the 290whp

Would be expensive, but an alternative would be to mix your own fuel...2 gals. of VP's unleaded extreme would give you 93 octane (17+2),as it's 110 octane.https://uploads.tapatalk-cdn.com/201...bc5e7451a5.jpg

Tires and drag times
 

Also be sure your running a good summer/ performance tire in the drag strip. I took my michelen all season tires to the strip and learned the hard way. Best time was 13.4 I was shooting for 12.7-12.8. Tires were completely runied by the end of the day. I slipped through first second and third it was ridiculous.
