Actually looks a little funky in the first 10' or so. It looks sorta soft and then really takes off. Are you hammering the throttle or are you squeezing it out of the hole? I think you key to a 10 second pass is in the 60'. What's the drivetrain combo? Looks really strong after it gets moving though - that was a nice pass. Keep the video coming. Now the race is on between you and Jeep - who gets into the 10's first Twisted Evil . By the way was this the first time out since the "incident" a few years back? Clay

Not the first time out since accident....but is for this year.

As for the "bobble" on the launch. I always had a traction issue or three Confused
First few runs it was sticking great, then it went away. Lots of people had issues and the track was resprayed then drug....great traction again.
I wasn't hitting the N2O until 20'-60' out...but that time I nailed the gas, it stuck,so I hit the button (I was late on the juice)... on the 11.30 I hit the button almost on the launch.

Thats why the double wheel hop Rolling Eyes

11.75 off the trailer with traction.

low bottle pressure (800-900psi) on 100 jetting 11.30 about 5' out.

I would hit it off the line but traction is hit/miss Sad

One thing I can point out is the rear gear / tire combo. A 4.11 rear with drag radials is going to be VERY tough to make work on a street car - power delivery is too quick to be controllable - much more so with nitrous. With what you have a set of slicks and spray from home would be the way to go. It should be able to stick a 150 shot from home with a 28" tall slick. Might have to do some shock tuning as it's hard to tell exactly what the rear end is doing in the video. Clay

i didnt realize you were running radials. spraying out of the gate would be a waste. what kind of shocks are on the car front and back ?

We have a similar package. I have the Caltrac Monoleaf springs with the Rancho rear shocks. I don't remember off hand but I think they are set at 3 or 4. I bought John Calvert's own brand of front shocks. I had Comp Engineering 90/10's on the front. I found John's front shocks worked better on my Nova. I was really impressed with him he was very eager to help me. With me in the driver seat I believe we have the bars set at 2 flats.
Seems to work well for me. I run the 275/60/15 Mickey Thompson ET Street Radials. That's the biggest tire I can fit without moving the springs inward. That would also require cutting the stock gas tank, which I'm reluctant to do. I've had a best 60 foot time of 1.48, they are usually around 1.50.
My problem, I think, is that I have too much 1st gear (3.06) in my 700R4. With the 4.10 gear if I try to leave harder than 2400rpm I unload the tires. I can footbrake the car to 3500rpm but it just blows the tires off the car. I have a rear end noise so I'm figuring on going to a 3.73 to see if it helps. I want to keep the 700R4 because I drive the car on the street quite a bit, especially back and forth to the drags.
Please keep us up to date on your quest for the 10's.

I have 4 leaf springs out back which could account for the shock settings ?
Once these 275/60's ware out I'm looking at the 295/55's which will fill the wheelwells Smile


BTW what you run and your set-up ?

The car is still heavy enough to warrant the setting below 90/10.
I would go with 80/20 or whatever the setting is below that. The car takes too long to react and the slower rise will generate a better launch. Cal-tracs and a set of mono leafs would help too. What you running for tire pressure might need to be reduced. I was running that and never hooked. I lowered the pressure to 12 lbs and low and behold the front end was 3 feet in the air.
