Tube vs after-cooler for comparison.....
I thought I either heard or dreamt that Dreadnought was pretty close to it's limit as well. As you mentioned varying speeds, sure it could've been pushed forward, flat out, all the time, but it wasn't necessary. 426 average, I assumed 435 was TOPS. Considering the fastest she's put down was 459, on the old course, with the tall tail, and the old timing (add about 10mph to today's speed), that sounds right to me...
I think Will and I share the same concerns of 125" without Allison rods. It is good to hear that the 2019 set was bad bearings, not beat during the race. I'll have faith that with how well she ran at 110", 125" should be doable.
Keep it coming Mark!

Never got the rundown on what was changed in the scoop/doghouse prior to last year, but assuming it has to be a mix of both of these to be able to run the Dago/RRIII style scoop, and still get ample airflow to everything inside. I may be wrong, but I don't think the current scoop has an oil cooler exit door (or at least don't see any photos of it open). That would lead me to think the current setup is similar to an H-model heat exchanger that solely cools the oil, and the aftercooler takes on it's normal functions with the radiator - I just don't know where this oil cooler/heat exchanger is on MA (or on the H for that matter although I think it's just behind the engine). There are definitely some experimental changes that were done, and continue to be done going into this year.
Was Fresno the location where Dago was repo'd?![]()
