On a stock car, seeing whp gainst of 15-20whp is very common, and really good gains with other modifications such as a cat-back exhaust and/or high flow cats is documented all over the place.
For example, a full write up and dyno: STILLEN Longtube G3 Intakes. Review, Dyno and Impressions.
Our fascia is not necessary to achieve gains such as that, we've never had anyone see the fluctuation that motoiq did on their testing, and never got enough information from them to see why. We do not feel the difference should be nearly that dramatic, and may point to other things, their fans, etc.
Import Tuner just did a test on these components, and saw gains as well. The magazine issue should be out soon, but others have sneaked the results: Watch for Import Tuner Maazine - 370Z Mods Evaluation, Stillen/Uprev
The car will NOT run lean just with these intakes installed, and a tune is not required. If you do a full setup, including long tube intakes, cat-back exhaust, with the addition of headers AND high flow cats, it will create a lean condition that should be tuned for. Without the combination of headers and high flow cats, the A/F ratios are safe.
I hope this info helps.. |
Well Josh,
Glad you jump in straitened us all out! LOL
One of the reasons I went with Stillens G3 intakes was because of the higher than average gains, and the locations of the filters, plus the fact that the filters were made by K&N didn’t hurt.
I have already decided to order my CBE from Stillen , had in mind the FI, CBE but they seemed too low for 18” stock wheels.
Also felt the Stillen CBE were designed closer to OEM design, that I did not take for granted, many of these other X, H duel strait pipe designs , have issues with
drone and require large resonators to compensate for design issues at additional cost , just felt for me it was a matter of substance over style !
Plus I felt the Stillen gains were just as high and better documented!
I also felt it would be best to have continuity with intake and exhaust design.
Stillen also offered a better price and free shipping which also made the offer attractive for me.
Kinder late in the game, I’m just wondering if all of this CAI,CBE,HFC would be too loud for day to day driving”.
The mechanic from Nissan that installed my G3's said the same thing concerning the tune as you!
Well josh I've decided to throw my hat in with Stillen , so far the G3's intakes have worked as advertised. Once i install the Stillen CBE next week I'll decide on the HFC then I'll do a tune and go for a dyno!
Thanks,
Alex
