drag launch
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? |

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.

Re: drag launch
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.

Re: drag launch
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.

Re: drag launch
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.

Re: drag launch
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!

Re: drag launch
^^I would expect 14's easy with that set up with launching. Last summer I finally got around to bring my 94 down. Me, full tank of Shell 93, no spare, no jack, my 18's, Perrin light crank pulley, PRW radiator, and OTom's brake upgrade wieghed in a 3720. 4 runs. Second run was fastest of the night. 16 flat, with no launch, taking off in 3rd with a temp of 68 degrees I think. I"ll have to pull out the slips. Weight reduction is the biggest key on the SVX. It's got the power and throtle responce just needs to get that fat ass moving.

Re: drag launch
I wish I could lighten the car without losing the beautiful interior.All that torque could be put to much better use.

Re: drag launch
I am a fan of weight reduction don't get me wrong, but for this car I've decided that I want to know what it can do in full street trim. The car has a very lightweight 17" street wheel/tire combo (rota slipstream) and the overall diameter of the tire is actually slightly less than that of the stock tire. However, I do also have a set of black FD rims with some 245/45r16 bridgestones that I may take along and try out.
I just like knowing what it can do realistically. Weight reduction is great, but I'm not going for an out and out drag car. I just want to know what mine will do on any given day. Also, I was recently checking out ecutune's site and noticed he offers performance valve body kits now... Very tempting!
