I know it has been covered before, but I must ask... Are we SURE this will not cause further cooling issues with the partial blockage of the radiator with the bumper on??
Josh feel free to chime in on that also...

There may be a half hp difference...this is one of those things that makes no difference...

I agreed because its possible... I didn't think it would be this easy though.

Sorry, but things like these don;t make much of a difference. This is air we are talking about, not water. There's plenty of air and plenty of cold air flowing through there when the car is actually moving. If you want to talk about the details, you gotta take that into account too. The dyno is sitting still, granted there is a fan, but its never going to mimic the air flow it gets when you are actually moving. If anything it would have LESS heat soak and perform better on the street.

Yeah there's definitely a sound difference. I can hear them even at low RPMS actually.

Completely stock exhaust.

ok i have Question
If some water got inside the intake due to the place where they are . Is it going to effect the car i mean like while driving in the rain

Again, minor point that doesn't deserve any more discussion. Guys the ONLY time water will cause problems with intakes is if you are revving it when the intakes are under water. Otherwise stop worrying about the water.

But I must say, these results were somewhat confounding based on your earlier dynos. You said that when you dyno'd with no filters, you saw no gains. Suggesting that air flow through the filter was not a limiting factor. Now however, you see 15-20HP gains with the long tubes. If the filters truly make no difference in HP gains, then we are led to believe that 20HP gains are to be made by rerouting the air to the throttle body through these tubes rather than the stock airboxes? Is the stock airbox design that poor/restrictive?
Promising gains regardless of where they came from. I don't care if its some STILLEN black magic trick. This is a significant step toward the 300HP N/A mark. |
There's a few factors that lead to this. First of all, the corrugated section is gone. Second the bends on the intake are smoother and therefore better flow. Third the intakes themselves have a lot of surface area, more so than open stock intakes. 4th the diameter of the piping may have changed a little, tricking the MAF into thinking the AFR is richer than it actually is. Usually when you tune for these things in cars that need bigger intakes you do something called scaling, where you adjust for the bigger piping. Without tuning, the intake may be helping the car run slightly leaner (NOT DANGEROUS, don't jump to conclusions already, this isnt going to blow up your motor) which would be idea for making some safe hp. 5th, the placement allows it to draw colder air. 6th STILLEN designed this intake to work, that means lots of R&D on the design to make it flow and perform as well as possible with the motor.
