Here is a picture from last weekend.

How big in diameter is it? Printer will print 7.5”x7.5” but will do 9” high. So if it is more than 18” in diameter……or break it up into more mold pieces.

Where is my air cleaner Rhett?

At MIR two weeks ago. I have had the stub stack for years, but it never ran well and back then I wasn’t logging data. I knew it was hammering the air door open, but was afraid to really crank on the spring. Breaks pretty easy. First ran the CF housing at MIR, no stack. Needed to add fuel, then added the stub stack and it went 1 full point lean! Was already at .119 jet in the rear and .119 in the front with smallest rod. Pulled the rear jets out and went with a drilled .135 front jet. Then ran the 11.17, overlaying the .17 run and the this weekends run. It was a bit fat this weekend. I can go bigger rod to take care of that. Still have about a comfortable 1/2 turn on the air door left. It used to spike lean, then rich, then stabilize, with the changes. It spikes at the air door opening, then stabilizes. Lean spike lasts 1 1/2 tenths. Different bases from MIR and Cecil. Doubled the lean spike height with new one, but lost the rich spike. All this adds up to HOW IN THE HE DOUBLE HOCKEY STICKS, does Brian do this WITHOUT data logging!!!
 
The steel one I ran for years, knew it wasn’t ideal, but had no easy alternative. This is actually the first CF base, (Bill D. is now running it without the stub stack, but with his own CF lid.) the lids I made are 1/2” bigger in diameter. So we don’t need a skeletonized base. Pie tin still fits because the increase is outside the tin area. Will make him the improved base over the winter. He was too chicken to run the stub stack and Q fuel,told him to pull the rear .113 jets and send it! it would probably have turned his 11.03 into……..well, we will never know:):):).

Too much! A lot of effort has been put into making it lighter, but per the rules it is an all steel, all glass, full interior, all cast iron motor, full exhaust, factory wheels and tires 71 duster with legal roll bar and 2x3 frame connectors. 90% of the standard go-to's for lightweight I can't do.

Congrats on your low timeslip.

I actually still hold the New Zealand F.A.S.T. record here with my now ex. 1970 Plymouth GTX.

Fresh from a photoshoot and not long after a major car show - absolutely as heavy as it could be - the only thing different between then and when it left the dealership in 1970 was a set of BFG tires. - 275x15 rear and 235x15 front. No frame connectors or fancy mods at all.....pure stock, pump gas only, and it ran a 14.1 quarter mile.

Enough for the win over a similarly decked out 6-BBL '70 'Cuda.

The class has never been run since then, probably because I won it :rolleyes: That was about 16 years ago now.
