drag launch

[Famouspork]

1/8th mile drag racing starts april 1st in my area!!!!
I have experience drag racing, but with the svx, I wanna make sure it lasts, and that I get the best results on the track.
Any advice on launching the svx without overheating the tranny or breaking anything?

Be sure your AWD is working. You don't want to blow a front differential on the track.(or anywhere for that matter)

TomsSVX or Chiketd would most likely be the most experienced inviduals in giving advice for drag racing the SVX.

I have done it myself, but only at a 1500-1700rpm powerbrake launch. I have run the quarter mile just over ten times (on three occassions) with two different SVXs, usually achieving about 15.7-15.9.

out of all cars for drag racing, I would not choose a SVX. they are rather a slow snail, its the 3800 pounds that is not so great. its kind of a waste of your time doing so. you will not beat a thing, and it will cause a failure fairly soon to your car.

thats what I'm afraid of, breaking something. My AWD is working, the car doen'snt feel too slow either..I might do one or two races and that'll be it.I'll take my maxima, I know it'll take it all without complaining.

5 or 6 speed helps a lot with this, I launch really nicely with my 5 spd, I beat a ton of people off the line, only problem is the weight and keeping that power moving, turbo or s/c and all that would really help, especially with a fg hood n such.

If you're automatic still, it's fairly easy. Obviously you don't want to be taking your car drag-racing if it's not in good mechanical shape, but here's what I do to get the best launch when I'm at the strip.

1. Put left foot on brake
2. Right foot on gas all the way down
3. Let off when the tree turns green
4. Enjoy going down the dragstrip in a heavy, cumbersome, altogether sexy car

Then, let it cool off as much as you can between runs. In the 2 or so years I've had my SVX, it's been down the strip maybe...15 times, and if I let it cool down while I'm in the staging lanes, it can make up to a tenth of a second difference. Heatsoaked manifolds are NOT your friend, so just turn the car off and pop the hood to help it let out the heat. This is where a set of phenolic spacers or a bag of ice would come in handy. (or both!)

Putting your right foot all the way down on the gas while you're on the brake... well that's your torque convertors "stall speed." On my SVX this occurs at approximately 2600 rpm. It may vary from car to car a few hundred rpm, but that'll be the general area.

Anyway, my best so far is really not even that fast, (15.5@89) but considering the weight, the fact that it's an AWD automatic, and how few mods it had at the time, that's not awful. A manual swapped car would be faster because of less physical weight, better gearing, and a more efficient driveline. Consistancy is the SVX's friend though. When I could keep it cooled down to the same temperature run after run, it was within .05 seconds each time. My 60' times are generally right around 2.3 seconds. I don't know for sure, but that's probably normal-ish.

And that's how I do it. Now honestly, you can't go drag racing and expect no ill-effects to happen. Unfortunately, that's just the nature of the beast. However, keeping your car in good shape, and knowing the warning signs of catastrophe can keep you going back time and time again!

I'm hoping to crack 14's this season on the stock tranny. I have yet to install a shiftkit, ECUtune 2v7, and I recently added my tomsvx style intake. I know it's a bit of a stretch, but I also think this car's got plenty more power in it to open up!
