Just got back from the track. I keep beatin' my old records every week. This thing is haulin' a$$ now!

New best:
2.027
5.795
8.989
76.64 mph
11.720
14.224
92.28 mph
Now, my old best was 14.35 at 95.3mph. The reason in the mph difference. Well there's a few theories behind this. The track, about 800' down it goes uphill. OR my fuel curves (stock computer) aren't supporting 16psi.
I went out in M&H 23"/7.5"/15" slicks, open downpipe, 7 gallons of 94, 3.21 gallons of 110 octane, 16psi boost, 40psi rear tires, and anywhere between 17-12psi in the front tires.
My next pass after my best looked like this:
My Spirit..........My older bro driving our infamous Hemi Charger
.762................ .494
1.968 :cheer2:....2.079
5.786.................5.888
9.017.................9.011
75.49 mph.........78.41 mph
11.774..............11.649
14.302..............14.003
91.59 mph.........99.68 mph

Okay since my first best pass I turned the boost up a little more, dropped the tire pressure from 15psi to 12psi. So the tires SHOULD hook up better; trust me they did! God 1.9 shorties slam yeh back in your seat! So why did I slow down a tenth when I should've gained 2/10?
Theoretically my car should be 13.8's. Why? Look: (this is why I included the Charger's best time of today) I had hm by 1/10, kept pulling away from him until the 1/8 mile where he caught me and proceeded to pull away. Being 1/10 out of the whole on him, I SHOULD have him by 2/10. Meaning 14.003 - .2 = 13.803.
I'm thinking my fuel curve isn't supporting 16psi of boost, the race gas is just helping it slow down a little. I run it fine on street gas (94) with no detonation, I have real clean plugs. So tomorrow we'll by slapping in a FWD Performance Stage 3 computer. See what that does. If not we'll slap in +20's and an AFPR.
Last year I had many problems at the top end, past the 1/8 mile. I solved them by swapping in a 255 l/hr pump and a brand new torque converter (both our guesses of what went wrong).
Whew, sorry so long, lots of information to process.
I'll post a few videos later. :eyebrows:
