Did any of you notice a nice soft hum while in lower gears, and at lower speeds ( Below 30mph ) ? I now hear a nice soft hum, kind of like a turbo, sounds very sexy.. anyone else get this sound?

Also, I noticed a big difference in how smooth the car is in idle, not sure about power gains, because it's very hard to tell if power was added (1-3hp) by sitting in it, but it does seem to have slightly better accleration, not sure if it's my head, or really does.

 

Read the fine print in my sig...

 

Ricky - I don't hear any kinda hum... just a slightly fuzzier overall exhaust note. VERY VERY miniscule, barely noticeable. No hiss.

Droid, I call BS on that.

Do you realize you would see that kinda difference just between running 2 dynos, about 5 min apart from each other ? The car is very sensitive to heat and many other factors.

There's no way you'd see such a specific gain/loss unless you ran many tests within the same parameters. Why don't you clarify how you got those results ?

 

I will GLADY quantify those results!

Read this thread. Make note of the mention of the conditions, almost identical with the temps being 1-2 degrees higher on the second series of runs. Pay attention to the baseline with the K&N (runs 001-003) and how I gained < one (1) HP on each successive run. Pay closer attention to the Paper element runs (004-006) where I hit 241.2 HP right out of the gate.

Still call BS? I guess SKiDaZZLe's ZERO gains from the INJEN is ******** too, huh? I tell you what is ********, putting mods on while the car is strapped to the dyno and claiming victory. SKiDaZZLe and I both ran our respective "mods" in for a good number of miles before going back to the dyno. I dropped that paper element in a full seven days in advance and put ~275 miles on the car. The ECU does not adjust in 15 minutes of driving as some manufacturers are claiming.

Note: SKiDaZZLe's runs were actually 002 and 005, one month apart, not 002 and 003 as I erroneously stated in that original thread.

 

Droid,

Whens the NISMO kit going on? I am eager to hear your opinion on the NISMO suspension vs. the stock bounce. Check out the thread on the Eibach install. Kinda of interesting.

 

Droid,

You think the Nismo air filter will make any difference ?
