2008 G35 Sedan-Blue Slate/Black interior.

Just wanted to announce my mod results so everyone will know what the 07-08 G35 sedan is capable of achieving with bolt on mods only.

MODS

STILLEN 3rd Gen. Long Tube CAI
STILLEN 2nd Gen. Cat-Back Exhaust
STILLEN High-flow Catalytic Converters
STILLEN Long Tube Headers

These mods alone added 45 WHP and 40 ft/lbs trq to the wheels.

TUNE

UPREV OSIRIS-Tune done at GoodSpeed Performance Lab in Scottsdale, AZ on the MAHA LPS 3000 dyno, the most accurate dyno in the world.

Tune added 20 WHP and 15 ft/lbs trq at the wheels.

OVERALL RESULTS

Boosted G35 from its factory 265 WHP to 330 WHP
Boosted factory 235 ft/lbs trq to 290 ft/lbs trq at the wheels.

***With the G35's 15% drivetrain loss these results translate into 380 HP and 333 ft/lbs trq***

Side note: MPG's have taken a hit under city driving only. I am averaging 15 MPG city (Less under hard driving obviously), however highway cruising MPG has been un-affected.

 

You have a dyno chart for this?

 

No I do not, apologies.

 

Then how are you determining how much HP you gained?

 

I was shown the computer graphic of the dyno result and it showed 330 WHP and 290 ft/lbs trq. The MAHA LPS 3000 dyno has the capability of factoring in the drivetrain loss and after the translation it came out to 379.5 HP and 333 ft/lbs trq. I should have asked for a print out, but forgot.

 

Question:
How can you have high flow cats and long tube headers? Long tube headers generally are cat-less on our model.
Maybe you mean the short tube, "high flow"?

 

 

tim2rice sticker addd hp too

 

How much was the tune alone? I live near there and looked at their site for options for my 911 turbo and it was insanely priced IMHO.

 

I would take any dyno reading with a grain of salt. The only way to really tell is to take it to the track.

 

How did you get baseline numbers?
Why couldnt their advanced dyno output a graph for you?
How did you get Stillen long tube headers that they dont make? Did they make a custom one-off pair for you?
"Boosted" implies forced induction, don't use incorrect terminology.

I think you either remembered the number incorrectly or their dyno is super super generous.

 

G37s with Stillen intake, Stillen headers, ART Pipes (better than Stillen HFC), Stillen Exhaust and Osiris tune. Almost 100% idential to your setup, except better engine and better cats. 323whp 262 tq



Either your tuner is a god among tuners or numbers are inflated.

 

Got em

 

Also stillen doesnt even make long tube headers.

Maybe a ploy to get people to that dyno in AZ

Who knows
