Dragster 503, The overdrive limits come from the SFI 34.1 spec. The idea is to insure that the rods exit the engine while the blower is still...
The highest overdrive that I was aware of on a T/F dragster last year was '56 over. Man, did that thing thunder in the pits! About knocked several...
Bounty Hunter, Read the thread in which I talked about the stiff mag drive shaft. It's not the MSD 44 itself that tears things up, but if the mag...
Mike, I know it'll be tough for you to heed your doctor's advice, but take it easy and don't wreck that rectum! [img] Best wishes, and a...
Wow! Did I ever sink the hook with that one! Just call 1-900-555-JERK ;) . Just kidding! But from the amount of E-mail I've gotten asking me to...
After fixing the mag drive gremlin and thanks to Brian Scollon at GRP for developing a really good connecting rod, burning up the intake adjuster...
Mike, You lucked out. In a blown engine, as long as the port runners in the heads are larger than that in the intake manifold, it won't affect...
You've probably all noticed the abrupt jerk that happens when elevators finish inching to achieve floor level alignment. They aren't going very...
Will, have you ever noticed that every so often you'll make a glass smooth run with a really good set of incrementals, ET and MPH, yet the...
Sorry! I didn't intend to stop the harmonic dampener discussion. My apology. Norm
I wouldn't want to constrain this one, because to do so might kill a new idea. Here's a real riddle: One of the mechanics on a fuel car was...
Hey! I've just thought of an interesting and noncontroversial one to chew on. How about crankshaft deflection? Norm Drazy
Wow! This was like leaving a cherry bomb behind as you casually leave the high school auditorium! :cool: On a serious note, I'd like to see...
Also keep in mind that the MSD 44 with a rev limiter can be a real parts killer if the mag drive isn't torsionally stiff. The armature in the...
A comment regarding the need to change the rotation of the Promag 44: Do you by chance run a Fontana engine? If so, the cross-axis gears in its...
Gene, You'd think that all you would have to do is look to the TAFC class for the answer, but once again it's not so simple. The TAFC performance...
Nuts! What a time to make an error with the confetti flying! Bobby Taylor went 5.54, not 5.56 on that second pass. Sorry. Norm :D
Ladies and gentlemen! (Confetti falls from the ceiling, fireworks go off, and an audience of thousands scream.) Both Mike Kosky and Chris Demke...
Jim, Today's belts are all Kevlar, which has an amazingly high modulus of elasticity. This number determines how much something will deflect when...
Since Duane now runs an A-fuel car, it's probably okay to talk about this. He used to run a 4.310 bore X 3.9 stroke engine with very high...
