What is everyone gaining in ET with spray?
I went to the track the other day and was running 13.5 all motor. I sprayed a 50 shot for the first time and it netted me a .5 sec improvement in the 1/4.
Is that good? Or should it be more?
I have not sprayed any higher because I need to make sure my A/F and timing are ok.
On motor I ran a 13.4 at 96 with a 1.77 60'. On 150 shot I ran a 12.2 @ 107 with a 1.64 60'
Is that with a stock 5.3? A 3600 stall and no cam?
So you gained 1.2 with a 150 shot or roughly .4 for every 50 shot. So I am headed in the right direction so far. Can't wait to spray 200.Quote:

Sounds like you sir need a stall haha .5 is pretty good for just 50 a lot of people say they can barely feel a 50 shot(fun bc so man claim a huge difference from CIA which net a 10ish hp gain haha) 13 flat with a 50 shot aint bad through a stall and 200 shot and you are prolly looking at some high 11's if you can hook.
Yea mine is with a bone stock 5.3 with a 3600 stall. Before the stall my 60' didn't change with spray either Bc it kicked in after the 60'. Get a stall buddy and put the 150 shot jets in it and smile lol
I ran a 13.1 on motor then ran 11.8 on a 200 shot with all my crazy popping issues, my 7.40 1/8th mile equates to about an 11.4-5, id say .5 on a 50 is good, one thing to know is nitrous creates its own atmosphere so when its hot outside your times should stay relatively the same, take this for example last year in perfect weather i went 13.1 on motor, this year at the same track in 90 deg. Heat i went 13.9 on motor a 12.5 on a 100 shot, my best ever on a 100 is a 12.1 so your 50 shot seems to be right on track :thumb:
I would get a 3000+ stall but I am going to be installing a turbo and was told not to stall or gear it to high. So, stock 3.73's and my 2600 stall for now.Quote:

Does anyone know where the stock fuel pump runs out of steam rwhp wise?
That's a really good question about the stock fuel pump, I would like to know that too. I think I'm going with the new aeromtive 340. The Camaro has intake and headers only and my best pass was 12.6 @ 113 with. 2.0 60'.
Also interested in stock pump RWHP limit.
Im surprised that just a 50 made that much improvement. Maybe its just cause I don't know too much about N2O.
I race my brothers 2010 Camaro and my best was a 12.81 with just headers and tune. Then with a CAI installed I ran a 12.59.Quote:

The stock O2's were in the 900mv range so I think I ok for now.
I went to the track today and managed a 12.59 on the 100 shot so I am still on the .5 sec per 50 shot path, lol.
Next I will take it up to 150 and check fuel pressure A/F and timing along with swapping out the TR6's for some BR7EFS's.
BTW, the DA was 1800 and my mph went up by 8.
15 flat on motor. 13.8 on 100 shot.
