60' times also 1/8
Below u will find my 1/8 times, the first pic is my old number 480 rwhp n/a with a couple of nos runs bogging down. The second pic is my newer numbers 507 n/a and 675 rwhp with the 200 hit. The motor is a 415ci and a th350 4k stall and a trans brake, Rear is a 9" with 4:11 and a spool mt drag slicks with tubes 28" tall. 40psi front and 15 in rear. I don't know if the difference in times from n/a to nos is normal or should I be expecting more. I'm launching @4200 off the brake and 2 step, the nos is coming on @4300-6800. As of right now I forgot where my Viking da front and rears are set at though the rears are stiff. I know that's crucial but really I forgot. I know I am lacking motor wise on my 243 heads that are p&p,also my headers that are 1 3/4. Nos is an outlet 102 plate kit.
Where and how can I improve?
How much faster is a 200 hit vs a n/a run?
Lastly again I'm new to this and know I need more experience/intelligence to get all this down.
Also I think I will be running outta gear if I do a 1/4 mile pass with the nos? I think I was almost on the limited when I crossed.

On a 3650 pound stick car that makes 450/420 on motor we pick up right at 7 tenths as well and around 10 mph in the 1/8th

I quoted the wrong person should have been the comment below. Sounded like he thought 100 shot was equal to .7 always, so I was explaining the different effects on different cars with nitrous. In his later comment I seen he understands.
"I'm not a nitrous guy, but I always thought for a 100 shot you would gain around
7 tenths."

oh yeah, upper 6.4's with a car making 507na at the tires plus 200 shot seems slow to me unless it's a 4000lb car. I think it should run that with 80-100HP less.

Well I think your 60 foot times are the issue. Not sure what your car weighs in at? Nitrous could be causing the convertor to blow through resulting in higher RPM's with 28 inch tires on the back you should have plenty of RPM's left in the 1/8.
My car usually picks up .5 tenths in the 1/8 mile on a 125 shot of dry at the air lid. I am not sure what that is at the rear wheels! Also my car usually picks up a solid tenth in the first 60 foot between NA and nitrous.
Hope this helps!
