Saturday night points race. The truck runs very consistant. Won first round against a red light and ran a 15.049 on a 15.05 dial. A win is a win. First rounds this year are easy. It's the second round I'm having problems with. Last week I red lit in the second round with a -0.027. This week with a -0.026. Tomorrows racing will probably be rained out. Forecast doesn't look good. If it looks ugly at 8AM, I'm staying home. I hate sitting at the track waiting between rain delays.

 

how far atre you from the track? and i have a nother thing to ask you . i see you have a pretty stout bbc under your hood . i am building a BBc for my camaro . people are telling me i am going to have a hard time getting the car to hook? i am useing a 29x10.5 slick. with all that weight under the hood how do you get it to hook?

 

I'm about a 10 - 15 minute drive to the track.

I run MT ET drag slicks 29.5 x 10.5. Traction depends on how much torque you put to the wheels.

My engine puts out an estimated 770 pounds of torque. I'm putting that through a 1.76 first gear powerglide then through 4.56 gears in the diff. That works out to 6180 pounds of torque to the wheels at peak torque which is about where my launch rpm is. I'm launching at 4500 rpm but my converter stalls at 5700. That gives a slight buffer as the converter flashes which softens the hit.

Without blowing the tires off, the track needs some good prep and I need good weight transfer. Proper suspension setup can keep the tires planted to the ground. If the track is poor then I don't hook up but if the track is good and sticky, I launch really hard. Large oversized tires in a tubbed out car help in traction but are mainly for consistancy. The less chance you have in spinning the tires, the more consistant the 60' times are.

My car is very nose heavy 60/40 weight ratio but it's not front end heavy. It's rear end light. The heavy rear glass and deck lid were removed last year for Lexan and a piece of sheet aluminum. The front weight of my car is about the same as a factory car but there's nothing factory about the front end. It's all race car.

 

thats a lot of TQ. to the wheels . do u pull the front tires every time you hook ?

 

Yes, even with a nose heavy car.

You got to love them Big Blocks! shout out to all them 3rd geners with rats under there hoods ! holla!...LoL

 

You need to soften the blow on the truck. Change the air pressure, leave the line at a slightly lower RPM...

 

Soften? I was so used to launching the car that the first few T&T passes with the truck were .2xx reaction times until I got used to staging deeper again to get down into the .0xx range. I managed a perfect light last week. I haven't gotten one of those with the car ever. The red lights were just a slight jump at the light. Over anticipating the light.
