At the last race in October I broke the 9 in. center section in my D-50. That night I ran my quickest E.T. and 60 ft. so far. I run 1/8 mile and it was a 1.34 60 ft. ,6.34 @ 108 mph. I had another center section with a mini spool and 3.50 gears so I put them in for now. How much do you think it will slow it down. I had 5.14 gears last year. It is a Indy 360-2 headed pump gas 394 c.i. with mufflers and Drag radials. It weights 2950 lbs with me in it. I will be going to T&T tomorrow.I will let you now what it runs. Glenn....

I have not put the 1050 on it yet. I have not bought a fuel pump yet. Plus I do not want to change more than one thing at a time. I wanted to see what it runs with the gear change. When I had the 360/380 HP crate motor in it I did the same gear change. It had run a best of 7.46 with the 5.14 and ran a 7.60 with the 3.50 gears. I had a 1.53 60ft. with the 5.14's and 1.67 with the 3.50 gears. So maybe it will run some 6.50's in 2nd gear.

8 in. PTC flashes 5200 - 5500 it seems to be looser with the higher gears. I was shifting at 6800 and crossing the finish line about 6800 with the 5.14's. I am not sure where to shift at tomorrow, I am sure I will go through in 2nd gear. I have another center section that is borrowed that has 4.56 gear in it. I might try in a couple of weeks. I am afraid I will break the cap in it too.

Is your 8 3/4 back braced.. also if you put load bolts in the back, that really helps the stock caps

The 9in. is not back braced and it has a 727 in it. I am leaving now to go and see what it will do.

Just got back from T&T and the 3.50 gears did not slow it down that much. The best pass today was 1.42 60ft. 6.46 @ 107.60 crossing the finish line in 2nd gear.
