Working out a couple bugs, tunes off, 700 psi in the bottle with the dry kit. Think I need some bigger tires, shifted 4th around the 1100' area. 26 inch Hoosier radial with a 3.42 gear. Click the pic for the video.

 

not bad. But dont run that bottle with less than 900 PSI.. not worth the issues.


Dont mess with the setup. Get yourself a GOOD nitrous tune (make sure your AFR is dead on with nitrous) fill that bottle up, heat her up.. drop the hamma and enjoy!

 

I would be more worried about reading the plugs then making sure the AFR is dead on, esp with a dry shot. Plugs will tell you a more accurate story of the run and tune.

OP, what was your tune like on that run? Timing and all.

 

Please tell me that 700 psi was a typo....

And I agree with what Josh is saying here, you need to be reading the plugs then comparing that to the AFR readings you're getting. The AFR gauge is not something you live and die by, it's a tuning tool you use just like looking at your oil pressure gauge seeing that it's low and then checking the oil level on your dipstick.

It also doesn't sound healthy the way it jumps up and down with rpm under load.

It was a good first pass, at least it didn't spin or break. Now just focus on the tune and get it cleaned up.

 

Yeah I should have added the plugs readings.

 

I know all this stuff. Just wanted to hose it down and see if it would pick up. I'd attribute the surging to the cold bottle. I didn't really hear it in the video, but I sure did in the car. Regardless, still picked up 10 full MPH, which makes me hopeful that I'll get closer to my goal. Planning on trying it next weekend with another kit on top.

 

So you're not going to try to clean the tune up?

 

Oh the tune will be cleaned. Don't you worry. I think it's actually more of a trans or converter slip issue. That was just quick and dirty, this weekend will be actual testing and tuning. I think 10.60@128 is a good starting point.

 

Car looked dam good in the parking lot at KOTS with the new weld wheels on it!! Dark blue ls1's are my favorite.

 

Good deal!
