Forged Performance: Stillen SC Custom Tune and Review
 

This is actually the first Stillen SC we've gotten our hands on for tuning. This local client does much of his own work, and after wrapping up most of the installation he brought it down for me to tune.

Stillen provided a basic 91 octane UpRev map that was pretty rich out of the box which resulted in that pretty low 290whp baseline you see there. After a few hours on the dyno, the car was a completely different animal. Good kit, nice fitment, not too noisey and consistent power after tuning was completed. End result was 373whp (stock cats). For reference, a typical stock 370Z does about 250-260 on our Dyno Dynamics.

Enjoy the photos. :tup:

Great results with a good tune, would the car put down roughly 400whp on a dynojet then? It would be awesome if you guys had some video too!

Nice numbers. What's going on with all the missing body panels?

Sharif, adding this build to the finished build list.
What year is the car?
Transmission?
TQ?
8PSI?

Thanks.

decent power for having stock cats. I'm interested to know if thats the bigger pulley too...

thats gotta be low boost! is so then good numbers

Z looks low.. It may have needed help to get up and onto the dyno.

The SC kit looks better than I originally thought. I like the rims too. Vid would be awesome! In the meanwhile I'll wait for the answer to the other questions.

Customer had just finished the install, so bumper was off and new side skirts were out for painting. And leaving the stuff off did make it a lot easier to mount the car, given it's very low ride height

2010, 6MT, 300lb/ft, 9psi

This is the one boost level....9psi. Our dyno reads very low, so this is a pretty solid number.

Once John has the car completely back together, I'll make sure he brings it by for a few photos. :)

whp losses through the heavy wheels and tires he is running, as well...?

Thanks for the info Sharif.

This is so much more important than people realize...heavy wheels SUCK.

Desent numbers Did you return it for 93? Or leave it at 91?

Sharif,

By comparison, I know you guys have a few GTRs roaming around there. What does a stock GTR pull on your dyno?

The tuning was done for 93 octane :)

Stock GTR's put down around 380-400whp on our dyno.
