I finally got out to the 1/8 track last night, here are the results:

r/t .154
60' 1.64
330' 4.619
1/8 7.09
mph 98.86

My setup consists of NX DP kit ,Ported AFR heads 217 cc, ported lt4 intake,37lb injectors, 58mm t.b. , 240/246 cam, th400,art carr 3600 on t-brake na, hals shocks, skinnies, m/t 28 x 10, 3.73 gears. My raceweight with me is 3400

Last year when I had my vig 4000, I cut a consistent 1.47 - 1.50 60'. I played around with the shocks and tire pressure. I was running 10 lbs in slicks cold. This was on 150 shot, so If I can get my 60' down to where it was last year, ill be running faster on the 150 than the 250. How much pressure are you guys running in your tires that have t-brakes and nitrous. Do you guys think I could have a 10.50-10.60 car on the 150 shot? What else can I do to get my 60' times down? Thanks in advance, Chris

 

Nice times! close to triple digits and 6's in the eighth!

 

thanks, i guess it will just take some tweakin at the track, and a sticky track WOULD BE NICE

 

I've run as low as 10 but prefer 12-14. I found 10 to be too unstable once I got to 90+ mph (swayed too much). What kind of stall are you running and what does it flash to on the bottle?

 

I'm running a 9.5" art carr, it flashes to about 5300 or so, its hard to see, Im just trying to keep the car straight

 

any opinions on cuttin my 60' times? lower than 10psi in the tires

 

That thing is moving. Was that on motor? What pinion angle are you running?

 

I'd go up...sounds like you're wadding up the tires. a little bit of wrinkle is all you need. Try 11.5 psi cold.

 

I tried 12,11,10. 10 hooked the best, i'm, pullin the wheels 4 or 5 inches and carrying it out for about 30 ft, but my 60' time is only 1.64

 

damn mine stay on the pavement on 1.50 60'

id say theres something up, i ran very similar times with 306 cam only stock heads and 125 shot on a window from 4k-6400
1.50 60' and 7.0 at 100 all day, stock suspension 4.60-e with a 3200 stall stock wheels with mt dr

 

whatever works best for you then. I havent had much experience with 60'ing what you are, so take my advice lightly, lol.

If you go lower then 10lbs, i would run rim screws tho.

 

i do have screws, but no tubes
