How much nitrous will I need to run 8's?
Based on my 2 most recent runs below (NA and 150HP), how much nitrous do you think I would need to use in order to break into the 8's? I think my converter is still too tight even with the 150HP hit I have been spraying, so i suspect my sixty to improve a little when I up the jets... I currently have a ring kit and am thinking about trying a 300HP shot... current race weight is 3325lbs with a full bottle. My future plans involve getting rid of the ring kit (replace with DP) and A4 tranny (replace with glide & Tbrake)... The air was around +2000FT DA, we see 0FT to -1000FT DA here in the fall... I would love to see 8's with the A4 and ring kit, but don't know if it's possible?
What do y'all think?

How is the A4 doing for you? I would think if it's still clicking off clean shifts then the swap to the glide might pick up a little for you. But hopefully the transbrake would help with the 60' if your setup takes well to it. But you will save a little weight so factor that in and the better weather helps, but not as much on the bottle as a NA setup. I would think you will need every bit of the 300 shot to pick up that last .7 tenths though. Good luck on it, keep us updated!
On edit: After reading your post again, I think you will definately need 300+ with that being your only change to have a chance at hitting 8's as it sits. But if you swap over to the new parts I think you'll have it in the bag with the 300 shot

I am going to race at another track that is at sea level in about 3 weeks... I have already gone 147.9MPH there... Since then I got new tires and the car is ~100lbs lighter and I'll have 250-300HP jets installed... I might still have the A4 in the car and will shoot for 8's... the DA should be better than it was my last time out...
Here are my runs from when I was at that track 4 weeks ago...

Your motor is making great power with your current MPH. If you're shootin for 8s with the current setup I don't believe a bigger jet is the answer yet. Your short time (although the 330' doesn't show) really needs to be your key to quick ETs that will match your MPH.
Good luck and race videos kick ***, so keep 'em coming.

No doubt, with a better 60', that killer mph, the PG w/ brake swap, a better suited converter, your recent 100# weight loss, and some good weather at a good track you will be REALLY close to your goal already without adding a thing. THEN add some nitrous accordingly, IF you still need it, and 8's it is!

The cam seems like it's definitely doing alright Probably a good choice on holding off on that change as you know small changes will help you understand the results.
Patience sucks when power is just a jet away

My goal is to see 9's NA and 8's with my ring kit... Hopefully the glide with the trans brake will help make this happen... the glide itself is good for 40-50lbs weight savings, I also plan to get rid of the door bars, bumpers, pop up lights, wipers and anything else I can pull out without affecting the car's integrity. This should bring my race weight down to 3200lbs without the bottle... I still have 2 full months of racing left

Yes I do... It's good for a couple mph and it helps bring down the rpms at the big end whe running on the spray... You can see the shift light come on 100ft before the traps...

Thanks I am hoping it will 60 foot better with the 250hp shot.... The car hooks well, but the converter is so tight that it seems to launch better with more power... I drop about a tenth with the 150hp shot taking me into the low 1.4 range... It's gone 1.40 once... I think the 250hp shot would take it consistant 1.3's. I would lock it up...

IMHO if everything is right(with a glide or th400) and the car sixty foots decent (mid 1.30's) then you will need about a 350-400hp shot to get it there. If its a really cold day maybe 300hp will do it if you can hook it up. When you get into the 8's lets line up for a little cash at TMP? What do you say?

P.S. I will spot you the bigger engine and the better cylinder heads. Race weight 3200lbs on ET streets with one system??? OSCA True street rules????

Didn't your car already run well into the 8's? I think your carbed solid roller SBC makes as much power NA as my hydraulic cam LS2 with a 100hp shot neither me nor my car are up to the challenge this year... We'll see how things go this winter .
