OK, so I went to Irwindale last weekend for the Match Race Madness Solid Gold race. They had a T&T Friday night. I was not planning on doing the T&T because it was $100 and I did not want to drop the coin. Already spending quite a bit on fuel etc. But then I realized I had the car set on kill still after coming back from Legions. Literally nothing was changed. AND, I knew the DA was coming in. Lower humidity and pressure building up some and with the Low humidity the Tempature was going to DROP after the sun went down. So, I went for it. My rival Walter had run Three 6.16's the night before. I ran into him on the way in and he challenged me to beat his time....... First pass with minimal (insufficient) warmup was a 6.18. I got this. I came right back around and now fully warmed up and a little heat soaked waiting, I ran a 6.14, DONE! Now I cooled the motor (Blower) down with fans and went back out there and the car chattered the tires all through 1rst gear with a minor 1-2 hiccup. Of course! I was pissed because I spent all that time getting the car ready and the DA was -125 Feet. But, I figured what the heck and went back to the lanes for another run. I ALSO noticed the Power Chiller was not working. The car is usually a little slower with a worse 60 right at that transition point of 55 Deg. Car fully warmed up and no power chiller and I had it shut off and had to move it up 3 times. I am in the bleach box and I pull up the race cooldown Page and the Intercooler loop is like 20 deg above the target temp. Oh well. NOW here is where that 1.32 60 foot comes in. The DA is good but the car is not optimized at all. But I was racing a Camaro and he was staging with one of those bump devices way up on the RPM and he bumped through the beams. I was way up on my converter too and I thought the starter would activate the tree. BUT NNOOOOoooooooo. He just let me sit there trashing my converter and trans. So I went to an idle and backed out. By that time that idiot was staging again............ I was pissed and took my time going in now that he was fully staged......
With the Demon you can stall it up and when it gets to about 1800 RPM the shear or charge or something like that changes inside the converter and the RPM will jump up higher. It always freaks me out and I have a tendency to back off the throttle because I think the car is going to push through the lights. If you think about it the RPM is jumping up because it is torquing less and that should not push you. And, I thought I tried this with my other car and it did not seem to help any. So, I was pissed and I went way up there on the RPM and left it. And that guy was already fully staged. So I was likely 2100-2200 RPM and I staged shallow as luck would have it. Those 2 added up to a 1.327 60 foot and a 6.10 in that good DA with a car that had no chiller and was a little heat soaked (considering the conditions, not like in the summer).
What is especially good is I confirmed this in +900 foot DA the next day. 1.330 sixty foot with a 6.17 at 111.67. So a slower ET and Speed because of the higher DA. But the 60 foot! I made 10 passes and had four 1.35's, Two 1.36's and Two 1.37's. But just those 2 were at that extra high RPM staging shallow as possible (difficult with the RPM that high). Not sure if I want to do that all the time or not. But in good DA and on a PB it sure seems to help as long as the track is on point. Irwindale is usually not, so I am a little perplexed on that point as well. Maybe the compound they are using and these Hoosier 28X10.5R17 DBR's were grooving........
