First round and out is the sweet spot in Top Fuel. Moe used to strive to qualify 16th and lose in the first round. That way he could at least break even.

There are two types of engine builders. The volume guys are NOT the power guys. I went for reasonable power, reasonable cost, and as few comebacks a possible. Someone like Foxwell, though I don't get along with him at all, is going to give you as much power as he can for a given application. Chris is in that genre as well...(he probably thinks I'm a butt too, but he'd be unlikely yo say it... :D )

Two entirely different worlds.
I'm going to take that as a compliment and say thanks.
You're getting soft in your old age. :)

It loped like a flopper, and that's all that mattered.
In the 70's I had GK grind me a cam for a 390 that would not even idle below 1200.
I revved that sucker to the moon (and I actually believed the numbers on the bouncy Sun tach...)
Felt like I was Don Garlits going up & down Woodward.
Car was faster when it was stock - but who cared?

If I were building and already owned the pistons I would "fill the groove" and go on with life.
If I were having pistons made I would look into the Mahle 1.0mm-1.0mm-2.0mm ring pack if it was available in your bore size.
As racers we are fixated on WOT, but there are gains at part throttle as well.

I'd like to find a test that would tell us if lateral gas ports really work. Mostly because a piston manufacturer I really respect once told me "lateral gas ports don't work."
The late Moe Mills for one, but many other piston manufacturers and real engine builders have the same opinion about lateral gas ports. Vertical ports will not plug up when utilized in a properly tuned race-only engine.

"Real" engine builders?!? ? ?

On this topic of rings... what would be the main decider choosing between - .043 plasma moly vs .9 AP steel?
Example... 15.5 to 1 BBC 20 deg 582, VP14+ fuel N/A. With one of the goals being low maintenance. Would the moly be easier on the cylinder walls? Or is the .9mm AP steel the way to go?

Who are the “many other piston manufacturers and real engine builders” that don’t think lateral gas ports work?

Face it - you are an "unreal" engine builder. :)

As for lateral gas ports - combustion pressure needs to get to the back of the ring for sealing function.
If you have old school .0015+ vertical ring to groove clearances the pressure gets there around the periphery - lateral ports might not be worth much.
But if you've tightened that up for ring control like the big kids do these days - the lateral ports are the only way to send that pressure back there.

Or the new rings with lateral grooves in the tops.

The cylinder pressure has to equalize the pressure that the positive twist top ring has stored in it, before any cylinder pressure can get behind that type of ring design.

Lateral ports enable cylinder pressure to get behind a positive twist or neutral ring, the instant that cylinder pressure goes positive.

The only way......other then vertical gas ports.

There will be 13,000 or so gas ports that don’t work in engines built by not real engine builders taking the green flag in Florida in a couple weeks.

Nah I just think you're you. We're all a little weird in one way or another. The older I get, the more I understand people. Not sure if that's a good or bad thing.

the .9mm ring pack is really a good price, readily available and should be utilized on most street strip engines IMHO. If not a power adder I don't see why I would use more ring.

we use a shitload of the .9/.9/3mm package in our NA stuff. Its a great ring that doesnt cost exotic ring package pricing, and just works.
