Faster..Faster......Faster...........FASTER
I get on the highway this morning and I am cruising along at 65 and tap the throttle. Instantly the car responds and goes faster. What is this? I never noticed this before. Is it the new TPS? Is it the colder air? (60F) I tap the throttle again and the car doing 80. It just jumps to 80 with no effort at all. It talks to me. Yea lets go faster.... The car wants to go faster. I can hear it talking to me.

I was wondering when someone was going to bring this up...
For the past six years, I thought I was the only one subject to this phenomena. Most times, I find that if I drive normally (read: hard) the car has sluggish response! After coming from a long road trip (sustained high speeds, 90+ MPH) the car responds instantly! What's even more strange, her handling goes up a notch as well. The bushings suddenly feel tight to the point of almost no slop, as if a bunch of performance elves installed delrin and carsan bushings while I was asleep.
My conspiracy theory is partially cold air + moisture. I'm thinking that maybe cold moist air causes the bushings to swell and harden removing the slop from the suspension. The benefits to engine power go without saying. As far as how suddenly the condition sets in and goes away? Well, that's where the elves come in... |

on hot humid days.......forget it.
right now in memphis it is about 70 and no humidity. my car is like a rocket. powerlight comes on immediately and the car seems to really pull throughout the entire powerband.
like seraphim i too sometimes cannot get my powerlight to disengage. it really is odd. sometimes my car launches from a dead stop and spins the tires and other times i feel like i have 200lbs of bricks in the trunk. it feels completely random, but thankfully it usually acts right so the car feels responsive and is fun to drive.

Air charge density and performance
Even a small difference in the density of the air charge can make a significant performance difference. I once installed a better intercooler in my Buick (dropping air charge by about 3 deg C), and picked up 1/4 second on the G-Tech!
As temperature and humidity both fall, you SHOULD notice a change. Temperature for the obvious reason: denser air. Humidity because the more water molecules per gram of air, the fewer oxygen molecules, hence more O2 at a given density. There's also a seasonal increase in O2 content - that's really slight, but again, it doesn't take much. |

You don't have to floor it to get power mode engaged - you just have to press it quickly.

i agree mr. pockets.
but sometimes in my svx it doesnt matter how quickly you press the accelerator the power light will not come on.

I agree with Mr. P. Remember the SVX has a learning computer - after enough times of seeing certain inputs it adjusts its programming to be more in sync with driver demands.
I remember my SVX and how it responded. These cars were one of the first few that used variable intake manifolding. As such you'll find that not flooring them from a light will yield a much quicker response. The cause of the delay when flooring from low speed is the sudden air dump without the benefit of an accelerator pump, ala carburetors. The mixture is lean and it takes the computer and fuel system a little time to catch up. I think you'll find that just pressing the pedal down about a 1/3 and waiting for the engine to gather itself up before continuing to floor it will show you much better results than just stomping it down to the floor.

hey beav.....
that was a different perspective than i have heard before. i think i actually understood that. because it does seem like when i hit the gas about half way and then really get on it is when it responds best. thanks for the advice.

Yeah, it's kinda like what the ricey-bike pilots call 'getting up on the pipe'. Due to camshaft and manifolding, timing controls and exhaust the bigger and more wild bikes are fairly strong to about 4000-6000 r's then look out! That's when everything comes together and the bike tries to fly out from under you. Now you can understand the lay down position - it's not for starting from a standstill as much as it is when you're already going 60+ mph...

Maybe the oil in your struts has leaked out and they're starting to bind up from all of the friction...heheheheh
