Re: Nearly a 10 In My Mildy Modified 06 Viper - 11.19 @123.80 - A Heartbreaker Read
Great times. Any secrets you want to share on how to drag race the car? I just had a test n tune and my paxton viper could only muster up a 12.7 at 122. slipping all the way through 3rd gear. I have almost brand new PS2s as well ad it was sunny at about 55 at the track. Any ideas?
I have a little experience, what is it that you want to know?
For starters, the PS2 needs to have the tire pressure in the low 20's (24 psi, and work your way down if you need to). I know some friends with Invo's that run in the teens (18 psi). If your tires start to cup in the middle, you have gone too low.
Secondly, you want to get some good heat in the tires. I typically drive around the waterbox, and back up into the water. if you have street tires, when you drive through the box, the water will get stuck in the grooves, and leave a trail of water all the way to the launching area. This will cause you to spin. For the burnout, I usually put the car in 2nd, and drop the clutch at around 5,000 rpm to get the tires spinning at a very high speed to build heat quickly, while the car is rolling forward. You WILL have to steer the car if you do this, and remember to lift throttle and stab the clutch when the car starts to move a little faster. You don't want it to grip and snap something in your driveline (or worse, lose control of the car and wreck...and yes, I've seen that happen in person). If you have a line-lock, or can get from the clutch pedal to the brake pedal pretty fast, you can just break the tires loose and sit while they spin, until you have a decent amount of heat in the tires (smoke coming out). I know a LOT of people will tell you that with a street tire, you just want to wipe the tires to get road dirt off, but I've made enough passes in my car to know better. This should hopefully solve your spinning issue.
Most people on street tires will run a 2.0+ 60' when launching. The biggest change you can make in your 1/4 mile E.T., will be in that first 60'. If you are shooting for a certain time slip, disregard the person in the lane next to you, and the tree. When the light goes green, focus on lifting the clutch and giving enough throttle, to maximize power at the wheel, without overpowering the tire, and also making sure you have enough throttle to keep the car from bogging. THAT, is a very hard thing to do, as it requires you to hold the clutch at a certain point when the car starts to move pretty good. You lift the clutch too fast, and you either spin, or the engine bogs. Not enough throttle, car bogs, and too much throttle, car spins. Fun, isn't it?
The timer doesn't start until you actually trip the beam, so don't worry if you sit there for 5 seconds after the light goes green. If the car does roll a little forward though, the clock is ticking!
Let me know if you have anything specific you want to know, and good luck!
