I'm currently getting Sarah ready for Bowling Green.
I took her to US41 today to get some base line runs with the regular radials. Yeah I know, they don't hook. but I told myself, that if she runs anywhere in the 12's I'll be happy, even if I just barely break into the 12's that's fine. I was tuning for mph today and wanted to get close to 110. All runs were made in the left lane, car # 48. Weather was absolutely perfect, clear skies and 52-60* with a slight tail wind.
1st pass.
.773 O2, Zero KR, boost was on 19psi, fp at 43.5# static, 100 octane unleaded, 295/50/15 radial T/As set at 30psi. +10.9% fuel added at WOT, timing 1st & 2nd was at 21.7*, 3rd & 4th was at 19.7*. I foot braked to about 2400, it hooked but once the boost kicked in, it blew the tires off for about 40ft. Not too bad and was kinda what I was expecting.
2nd pass.
.761 O2, .5 KR, boost was turned up to 20psi, fp same, I turned the WOT fuel up to +12.5%, and upped the timing to 21* in 1st & 2nd and 21.1* 3rd and 4th. Launch was the same, foot braked to about 2400 and let the car pull herself off the line and going WOT about 10 foot off the line. I was letting the car cool down for about 30-35 minutes between passes.
3rd pass.
I got a little more serious with the tune this time. .757 O2, .7 KR, turned up the boost to 24psi and turned the WOT fuel up to +14.1% fuel. Turned up the timing to 22.1* for 1st & 2nd and 21.8* for 3rd & 4th. I left the same as before, basically creeping off the line and boy did she respond. Picked up 3mph on that run. To this point, everything was doing exactly what it should do, mph was going up, et was getting slightly better (even with my wonderful 60ft times
) and things were looking good. She wasn't yelling at me either, she seemed like she was actually having a good time. As was I. Tranny was/is flaring on the 2-3 so I knew I only wanted to make one more pass before calling it a day. And I knew I needed to go through the brakes because she was pushing at 1 psi.
4th and final pass for the day.
.757 O2, .5 KR, boost was at 24psi, I turned up the WOT fuel to +15.6%, lowered rear tire pressure down to 28psi, but this time I launched with 1psi showing on the gauge. She hooked up for about 5 feet, but when the boost came on, it was all she wrote. Spun for about 50ft but the short time dropped a tenth. Not too shabby.
All in all, I learned a few things today. She definitely responds to a good tune and she likes boost. This is a good thing. Tires should be here Tuesday and am planning on going to Tri State in Ohio next Sat if the weather holds out. I came home and swapped out front brake pads, they were oily & greasy, duh, no wonder she wouldn't hold any boost, I kinda had a feeling. This week, I'm going to install the front braces, 6piece body bushings, remove front sway bar, repaint my spare wheels, mount tires, install dual air bags, install new B&M Super Cooler, buy some C16, relocate SM to top of dash, adjust back brakes and head to Ohio Friday after work.
My battle plan is to make my first pass with the same boost, with pure C16 and turn up the timing to 26* in all gears and launch as hard as possible. Then turn the boost up to 26, adjust fuel if needed and E-brake launch if need be. I know at this power level, I'm gonna need to get my short times into the 1.60 - 1.57 range to get anywhere near my ultimate goals, and this will take 12-14psi launches. Might have to do the larger rear wheel cylinders and long shoes all around on the back tho, but we'll see. If she runs 12.00s I'll be happy, besides, I can't expect much with a flaring 2-3 shift. If she runs faster, well that's cool too, but I have a feeling I'm gonna have to get an emergency tranny freshing before BG. Hey Lonnie, if you read this I might be in need of your tranny services soon. Locals were freaking out over the regular radials and horrible short times and the mph. We had a good time tho. And tuning at this level really brought back a lot of old memories. So much easier than the old grey car. Not as fast of course, but I don't have any worries driving home either.
Thanks for reading and sorry so long.
