Yeah, I know about the hard lid. As a 12.7 truck the lid was always taken off at the drag strip. Here in oxygen rich western Washington the truck was a consistent 12.7 truck. Anywhere from 12.73 to 12.79. That was with a canned Predator tune.
With the MafIA and a custom tune the Wizard massaged that puppy to a 12.51. Two tenths came off its time. That's with the lid on so yeah I feel good about a 12.4 without the lid. In general every 100 pounds is worth a tenth so without that lid on it should be worth somewhere between .07 and .1.
The lid has stayed on for CCCA bracket racing as to me it's more about consistency than the best ET. One of these times though maybe I'll get the lid off and see what she'll do.
That 6 lber makes me nervous as I see from 14 to 16 PSI with a 4lber. Again, generally speaking it seems the stock rods can get real unhappy real fast with more than 16 psi pushin' agin'em. Doc, comments ?
Rather than push the boost on the Eaton causing more heat to the intake charge by overspinning the poor thing a better option would be a Whipple. A more efficient design and less heating of the intake charge. I'll pass on a KB as one, they're ugly, two customer service seems questionable and has for years, and three it seems to many of them have to get sent back in for "issues" too often.
With that out of the way a pair of them new TFS heads with these cams I got layin' around and a set of rods and lets pump up that Whipple.......for the 11 second zone......
