broke out
If I had stayed in it it would have run a 5.639. All-in-all a pretty good start to the year.
If I translate that 5.639 into a quarter mile time it would be about a 8.81 quarter mile time. But that is assuming I would have had enough RPM capability to carry me through the entire quarter. I shift off a timer. With the big tall old tires my 1-2 shift was timed at 2.6 seconds into the run, at around 6800. Over the weekend I gradually reduced the shift time down to 2.1 seconds. At 2.4 seconds the revs were around 7500 which is beyond my comfort zone for a mere bracket race 300. I suspect I'd be doing well over 7000 going through the quarter mile traps. I'm content to stay around 6800 so the valve train lives indefinitely.
But it is comforting to know it will rev to 7K+ without floating the valves.
I'm running a roller cam with 185# of seat pressure with lift at the valve around .660/.680.
I discovered a couple of additional advantages to the smaller slick set further inboard. I'll add to my original post.
A smaller slick set further inboard now aligns my tires in the same track groove as all the rear engined dragsters I race.
A smaller slick set further inboard now puts the tires completely inside the wheel tubs, eliminating splattered water and rubber on my helmet visor during burnouts.
On an entirely unrelated note I put the engine in my nostalgic Logghe altered together and fired it up in my spare time. There is a Nostalgia Comp race coming up in July for that beast so we're good-to-go. I have to get the engine in The Frenchtown Family Truckster RPU out of winter storage mode for the same race. My neighbor drives that one.
Stay safe. Race safe.
