STILLEN Exhaust & Gen 3 Intake Dynos - 18hp Each!

Denny McLain

Hi Josh and your welcome for the post. Watch what ya ask for regarding independent testing.

The car goes on the dyno tomorrow for baseline testing with 150 miles on the car. High flow cats, Y pipe and high flow intake filters have already been ordered and dyno time scheduled for Saturday to see how they work. Each will be tested individually and as a combo. Consistent cool down, consistent water/oil temps, etc. etc.

Trying to figure out the tuning as it is different, but next step will be tuning software/more dyno time to optimize the system. The majority of people leave a lot on the table due to lack of optimization of what they already have.

Maybe headers, full exhaust after that to see if there is any additional gains to be had. Intake?? We'll see how the mop flops, but I've owned three turbo cars and for sure, that works.

Even though there is a big difference between a small block Chevy and a Nissan motor, the same basics apply. Air in - air out - optimal fuel ratio - optimal timing = Horsepower. The good ol boy school of hot rodding still applies and dynos don't lie......Operators of the dyno do. It's a science and sound clips/butt dyno's don't work. Don't tell me it "feels faster", measure it under controlled condition and tell me then.

I have zero financial nor special interest in anything, just a passion for fast cars and what really works. Don't mind spending a few bucks nor letting others know.
