i am in serious need of some......what do you launch at?,where do you shift... techniques? tire pressure? suggestions? i spin spin spin, which is why i am asking.... am i letting off too fast ?

 

Put a LSD in the car. A whole world of difference
Different tires may help grab the track better as well

 

i have the factory upgrades....from what i was told those are good tires....

 

bump, come on track junkies...

 

Good tires for all year driving. Track you want slicks to grab the ground.

 

let a little pressure out of ur tires...and since u seem to only have the ARK DT-s...try launching at 2k RPM's

 

If your tires are spinning, here are the 3 best things to do:

1) Get some great tires (those who know me know I recommend the Toyo Proxes 4)
2) Put on an ingalls engine torque damper (stiffy) - world of difference - keeps the tires on the ground
3) Learn the clutch and practice practice practice

 

im spinning though..is it better to spin? is that good technique?

 

Is it better to spin your tires are you asking? No, you don't want your tires to spin. When they are spinning, they are not gripping. What kind of technique are you referring to? Are you trying to figure out how to take off hard from a light or something? You don't want your tires to spin out of control, you want them to grip..........this seems so elementary, i'm not sure what you're asking

 

okay, so i rev up to 2k and then moderatly let out the clutch? cause i have been just reving up to 2.5k and letting go on green.....

how bout shifting i usually shift at 6k and then it grazes 6.5k is this good?....

 

When you are trying to get max power out of your car, you want to bring it up to 6,000ish rpms and then change gears. In normal driving, you want to gear up at 3K rpm and down at 2K rpm for great gas mileage.

You are spinning your tires because when you are trying to take off hard, you are spinning your engine faster than the transmission can handle to firmly plant your wheels on the ground and transfer the engine power to the wheels. You only want to have the rpms at about 1K and then add throttle as you begin to come off of the clutch. You are spinning because you are overloading the tires and the clutch - it can't put that much power on the ground at once.

What you want to eventually want to be able to do if you are a drag racer or something, is know the cars limits. For max takeoff, you want to be able to know where the car begins to spin and give it just a bit less throttle than that.......You shouldn't be doing this however all the time. It is horrible for gas mileage, dangerous, and a guaranteed ticket.

 

no worries im not a traffic light racer, just an enthusiast who wants to get better times.

i was just trying to figure out if a little spin was worth the extra jump you get on the other car... idk. just looking for tips... any exact tire pressure?...psi?

 

I would HIGHLY suggest not spinning your wheels if you are looking for times. Tire PSI is based on your individual tire. I am running toyo proxes 4 225/45-17 and I run all 4 at 33psi cold. I find that very comfortable.

Like I said though, if you upgrade your tires, add an ingalls stiffy and practice launching, you will notice a significant difference. The stiffy helps to reduce wheel hop and transfer more torque to the wheels that normally gets lost in engine movement.

 

also for shifting gears...6k rpm's is a little too far. You wanna shift around 5600 - 5800 rpm's for maximum potential. After 5800, ur car doesn't make any more power and it's not gonna help you with ur time

 

How can you maximize the power zones of each gear? I've noticed that 2nd gear between 3k and 4500 the car accelerates better and in 3rd gear between 3500 and 4500. What are the power curves on the rpm scale?

What about tire slippage when engaging from 1st to 2nd, I get some tire screech when I lay it down, a lot less in my Fuzion ZRi's over the stock Yokohama's. I'd would think a little suspension work, springs or even coilovers would help drive the power straight to the ground.

What about a little more wild driving:
Cornering/Drifting
Mid Range speed accelerating
- moving from lower to higher speeds while shifting (up/down)

 

it was my understanding that our cams make power untill 8,800k am i mistaken?

 

Just because they have the potential to hold that much power, doesn't mean ur gonna reach it. The rev limiter will kick in way be4 8800. Usually the peak of your shifting can coincide with the rpm level noted at the peak of horsepower in a dyno chart. Stock dyno's (check one on the main tC page...the pdf form) show that around 5700 rpms and with a few mods like exhaust and CAI have been seen around 6200 rpms. So a good place to shoot for in maximizing power in shifting, would be in that range IMO.

 

thanx for the info, bump for any other suggestions....

New suggestions?
